ABSTRACT: Early hepatic arterial thrombosis after living-donor liver transplantation is a cause of graft loss and patient mortality. We analyzed early hepatic arterial thrombosis after pediatric living-donor liver transplantation.
Since September 2001, we performed 122 living-donor liver transplants on 119 children. Ten hepatic arterial thromboses developed in the early postoperative period. The 7 male and 4 female patients of overall mean age of 6.3±6.1 years underwent 5 left lateral segment, 3 right lobe, and 2 left lobe transplantations.
Among 10 children with hepatic arterial thrombosis, 8 diagnoses were made before any elevation of liver function tests. One child displayed fever at the time of the hepatic arterial thrombosis. The median time for diagnosis was 5 days. Hepatic arterial thrombosis was treated with interventional radiologic techniques in 9 children, with 1 undergoing surgical exploration owing to failed radiologic approaches, and a reanastomosis using a polytetrafluoroethylene graft. Successful revascularization was achieved in all children, except 1. Four children died, the remaining 6 are alive with good graft function. During the mean follow-up of 52.7±18.8 months, multiple intrahepatic biliary stenoses were identified in 1 child.
Routine Doppler ultrasonography is effective for the early diagnosis of hepatic arterial thrombosis. Interventional radiologic approaches such as arterial thrombolysis and intraluminal stent placement should be the first therapeutic choices for patients with early hepatic arterial thrombosis; if radiologic methods fail, one must consider surgical exploration or retransplantation.

ABSTRACT: RIFLE criteria have been used to determine the incidence of acute kidney dysfunction (AKD) after orthotopic liver transplantation (OLT). However, no studies have focused on the incidence of AKD after OLT in patients with normal pre-OLT kidney functions. Using the RIFLE criteria, we determined the incidence and risk factors for AKD after OLT in patients with normal pre-OLT kidney function. We retrospectively analyzed the records of 112 patients who underwent OLT from January 2000 to February 2009 with normal prior kidney function. We investigated three levels of renal dysfunction outlined in the RIFLE criteria: risk (R); injury (I); and failure (F). Preoperative, intraoperative, and postoperative variables were collected. AKD occurred in 64 (57%) OLTs with risk, injury, and failure frequencies of 19%, 11%, and 28%, respectively. Compared with those who did not develop AKD postoperatively, those who did had significantly higher MELD scores (19 ± 7 vs 16 ± 8; P = .018), more frequently use of inotropic agents intraoperatively (54% vs 35%; P = .070), more colloid treatment (300 ± 433 mL vs 105 ± 203 mL; P = .007), longer anhepatic phase (88.0 ± 42.0 minutes vs 73.0 ± 20.0 minutes; P = .037), and a greater incidence of intraoperative acidosis (64% vs 44%; P = .047). Logistic regression analysis revealed that MELD score (odds ratio 1.107, 95% CI 1.022-1.200, P = .013), duration of anhepatic phase (odds ratio 1.020 95% CI 1.000-1.040, P = .053), and intraoperative acidosis (odds ratio 0.277 95% CI 0.093-0.825 P = .021) were independent risk factors for AKD. In conclusion, our results suggested that, based on RIFLE criteria, AKD occurs in more than half of OLTs postoperatively. A higher MELD score, longer anhepatic phase, and occurrence of intraoperative acidosis were associated with AKD.

ABSTRACT: Four children underwent living related liver transplantation because of Crigler-Najjar syndrome type 1. Three were infants aged 2, 8(1/2), and 15 months, and weighed 5, 8, and 10 kg, respectively. Pretransplantation unconjugated bilirubin concentration was 22 to 30 mg/dL despite 12 to 14 hours of phototherapy daily. Patient 1, the 2-month-old infant, with unconjugated bilirubin concentration of 30 mg/dL, had a high-pitched cry, suggestive of bilirubin encephalopathy; results of neurologic examination were normal. Plasmapheresis and urgent liver transplantation were performed. Patient 4, a 13-year-old girl, had learning difficulties at school and attended a special class. Three patients received left lateral liver segments, and 1 patient received a left lobe. Biliary reconstruction was completed with duct-to-duct anastomosis. Bile leakage developed at the anastomosis in 2 patients, which was treated successfully with cholangioplasty. In all patients, the unconjugated bilirubin concentration normalized by day 1 posttransplantation, and no phototherapy was necessary. After transplantation, the 2-month-old infant with suspected encephalopathy exhibited hypotonia, spasticity of the lower extremities, and lack of head control. He died after vomitus aspiration during sleep at 10 months posttransplantation. The other 3 patients are alive with normal neurodevelopmental milestones. Irreversible brain damage may occur early in the course of Crigler-Najjar syndrome type 1. Urgent treatment including plasmapheresis, exchange transfusion, phototherapy, and liver transplantation may not reverse brain damage. Young infants must be evaluated carefully for subtle signs and symptoms of bilirubin encephalopathy. Liver transplantation is curative if performed before development of neurologic dysfunction.

ABSTRACT: Hepatic alveolar echinococcosis is an infectious disease caused by the larval stage of Echinococcus multilocularis, which grows primarily in the liver of an infected person and develops as a tumorlike lesion. In advanced cases, the organisms infiltrate every organ neighboring the liver and spread hematogenously to distant organs such as lungs and brain. Surgical resection and liver transplantation are accepted treatment options for early and advanced disease, respectively. Herein, we present case reports of 2 patients with advanced alveolar echinococcal disease that invaded both lobes of the liver and neighboring vital structures including the inferior vena cava. Despite the technical difficulty of the surgery, both patients were successfully treated with living donor liver transplantation. Liver transplantation should be accepted as a life-saving treatment of choice in patients with alveolar echinococcosis for whom there is no other medical or surgical treatment options.

ABSTRACT: Renal transplantation is considered preemptive if it occurs before initiation of dialysis. In our experience and in the literature, preemptive transplantation has been shown not only to reduce the costs of renal replacement therapy but also to avoid the long-term adverse effects of dialysis. Preemptive renal transplantation therefore is associated with better survival of both the allograft and the recipient. Our aim was to evaluate the outcomes of preemptive renal transplantation experience at our center. Since 1985, 1385 renal transplantations have been performed at our center. We retrospectively analyzed the 16/1385 recipients (11 male, 5 female) of overall mean age of 28.5 +/- 15 years who underwent preemptive procedures. The causes of end-stage renal failure were focal segmental glomerulosclerosis (n = 5), vesicular ureteral reflux (n = 4), Berger disease (n = 2), polycystic renal disease (n = 2), and others (n = 3). Ten patients were adults, the remaining six, children. The mean creatinine clearance and plasma creatinine levels of the recipients before renal transplantation were 13.5 +/- 8.5 mL/min and 6.7 +/- 2.4 mg/dL, respectively. All renal transplantations were performed from living related donors. The mean preoperative serum creatinine levels, mean glomerular filtration rate, and creatinine clearance rates of the donors were 0.8 +/- 0.1 mg/dL, 61.6 +/- 6.5 mL/min, and 112.5 12 mL/min, respectively. Two episodes of acute cellular rejection and one of humoral rejection occurred during a mean follow-up of 48.7 +/- 14 months (range = 25-76 months). The two patients who experienced graft losses due to humoral rejection or chronic rejection were retransplanted 2 and 48 months thereafter, respectively. At this time all patients are alive with good renal function. In conclusion, our single-center results are promising for preemptive renal transplantation as the optimal, least-expensive mode of treatment for end-stage renal disease.

ABSTRACT: After transplantation, diarrhea may be caused by infectious agents, drug-specific effects, metabolic conditions, or mechanical complications of surgery. Determining the cause helps to determine whether to initiate antimicrobial therapy and the duration of treatment. In this study we aimed to determine the causes of diarrhea in kidney or liver recipients. Fifty-two diarrhea episodes among 43 solid organ recipients were evaluated. The cause of diarrhea was detected in 43 patients (82.6%). Infectious etiologies accounted for 33 out of the 43 episodes (76.7%) in which a specific cause was determined: Giardia lamblia in 9, Cryptosporidium parvum in 7, cytomegalovirus (CMV) in 6, Clostridium difficile in 3, Campylobacter jejuni in 2, Shigella sonnei in 2, Salmonella enteritidis in 1, rotavirus in 1, Entamoeba histolytica in 1, and Blastocystis hominis in 1. Non-infectious etiologies were found for 10 episodes (23.3%): mycophenolate mofetil-associated diarrhea in 5, antibiotic-associated diarrhea in 2, colchicine-associated diarrhea in 2, and laxative drug-associated in 1. Non-infectious etiologies seem to be relatively common causes of diarrhea among transplant recipients. Therapy was adjusted in 5 patients because of mycophenolate mofetil-associated diarrhea. CMV and C. parvum, which are seldom seen in the normal population, were frequent causes of diarrhea in this group. Evaluating the transplant recipients for non-infectious causes of diarrhea is important in prompt diagnosis and treatment.

ABSTRACT: The aim of this study was to assess the impact of living-donor liver transplantation on the donor's quality of life. Among the 48 performed at our hospital from October 2003 to June 2006, 46 (27 men, 19 women; mean age, 37.4 years) were followed for more than 4 months (mean, 16.5+/-8 months). In April 2006, these donors participated in a survey that included medical and psychosocial outcomes. Seven complications occurred in four of 46 donors (8.6%): two biliary leaks, two wound infections, one incisional hernia, one portal vein thrombosis, and one deep venous thrombosis. For the donor with portal vein thrombosis, the vein was recanalized, and she recovered without treatment; a bile leak from the cut liver surface and an incisional hernia also developed in the same donor. The biliary leak was treated with percutaneous drainage, and the incisional hernia was repaired surgically. Fifteen donors were housewives, 31 worked outside the home, and 94% returned to their work. A change in body image was reported in 4.3% of the donors. None reported impaired sexual function. Complete recovery occurred in 86% of donors, 94% of the donors said that they would donate again if necessary, and 97% believe that they had benefited from the donation experience. In conclusion, almost all donors were able to return to their prior jobs within a few months of surgery, and most donors were satisfied with the donation procedure.

ABSTRACT: Biliary complications are critical problems in liver transplantation. Herein, we retrospectively analyzed the early results of an intraoperative transhepatic biliary catheter insertion technique for biliary reconstruction. Since November 2004, we have used this technique in 66 patients (32 children and 34 adults). In the new technique, a 5- F Kumpe catheter is inserted into the biliary system in 2 steps. One step is completed at the back table; the second step is completed during the recipient operation. Fourteen patients received whole-liver grafts, 25 received a right lobe, and 27 received a left-lateral or a left lobe. The mean graft weight-to-body weight ratio in the living-donor liver transplantations was 1.6% +/- 1.0% (range, 0.8%-4.1%). Intraoperative transhepatic biliary catheter insertion was performed with a duct-to-duct anastomosis in 60 patients and with a Roux-en-Y hepaticojejunostomy in 6 patients. Five biliary complications occurred in 4 patients. Two of these 4 patients had bile leakage from the anastomotic site during the early postoperative period. Biliary stenoses developed at the anastomotic site in 2 patients and from a nonanastomotic site in 1 patient in the late postoperative period. In conclusion, this new technique of biliary reconstruction with intraoperative biliary catheter insertion has significantly reduced our complication rate. Transhepatic biliary stenting seems to prevent biliary complications and makes it simple to maintain percutaneous access in the event that problems arise. Intraoperative transhepatic biliary catheter insertion at the back table is a safe means of providing good biliary drainage after liver transplantation.

ABSTRACT: Immediate postoperative extubation may reduce the incidence of postoperative respiratory complications after orthotopic liver transplantation (OLT). We evaluated the predictors of immediate tracheal extubation in the operating room (OR) in our patients by retrospectively reviewing data from all patients who underwent OLT between January 2004 and June 2006. The patients were divided into two groups according to whether they had undergone extubation in the OR (group 1 n=52) or in the intensive care unit (ICU; group 2 n=48). When compared with the patients in group 2, those in group 1 had lower mean preoperative serum creatinine levels (0.9 +/- 1 vs 0.6 +/- 0.3 mg/dL, P=.04) and intraoperative transfusion requirements (packed red blood cells, 35.5 +/- 29.8 vs 25.6 +/- 19.0 mL/kg; P=.05, and fresh frozen plasma, 33.1 +/- 15.6 vs 25.7 +/- 14.3 mL/kg; P=.01). The incidence of intraoperative hypotension and emergent OLT was significantly greater in group 2 than group 1 (33.3% vs 13.5%, P=.01 and 45.8% vs 21.2%, respectively, P=.009). On logistic regression analysis, only emergent OLT (P=.009, odds ratio = 3.5) and intraoperative hypotension (P=.018, odds ratio = 3.7) were significantly associated with a lower probability of immediate postoperative extubation in the OR. Our results suggested that hemodynamic stability and elective OLT were predictors of successful immediate tracheal extubation in the OR.

ABSTRACT: Living-donor liver transplantation is another treatment option to cadaveric liver transplantation in adult recipients. We report the outcomes of 49 right lobe adult living-donor liver transplantations performed at our institution between April 2003 and June 2006. The mean age of the recipients was 41.7 +/- 12.5 years. The median graft-to-recipient weight ratio was 1.2% +/- 0.4%. In recipients, the mean operative time was 10.6 +/- 2.7 hours. The mean number of blood transfusions administered was 4.1 +/- 5.1 units. The mean time spent in the intensive care unit was 2.3 +/- 1.5 days. In recipients, five vascular and five biliary complications occurred during the early postoperative period, and four vascular and two biliary complications developed in the late postoperative period. Thirteen of the 49 recipients died within 4 months of surgery. The mean age of the donors was 36.6 +/- 9 years. In the donors, the mean operative time was 6.4 +/- 1.6 hours, mean residual liver volume was 43.3% +/- 6.1%, and the mean hospital stay was 9.5 +/- 4.5 days. Two donors required an intraoperative blood transfusion. None of our donors died, but six complications occurred in four donors. The mean postoperative follow-up was 13.4 +/- 9.6 months. In conclusion, in Turkey, as in other countries, organ demand exceeds organ availability. Graft size presents a problem for adult recipients, but right lobe living donor transplant may be a life-saving option for these recipients when performed by experienced surgical teams.

ABSTRACT: Cardiovascular disease, malignancies, and infectious complications are major causes of morbidity and mortality of renal transplant recipients. Mortality rates vary between 16% and 40% in an intensive care unit (ICU). The aims of this study were to identify the types incidences of respiratory problems that affected renal transplant recipients admitted to the ICU during long-term follow-up thereby determining the impact of respiratory problems on mortality. We reviewed the data for 34 recipients who had 39 ICU admissions from January 2000 through December 2003. Twenty-four admissions (61.5%) had at least one respiratory problem at admission or developed at least one during the ICU stay. The most frequent problem was pneumonia (n=18, 46.2% of the 39 readmissions), followed by acute respiratory failure (n=10, 25.6%), atelectasis (n=9, 23.1%), pleural effusion (n=8, 20.5%), and pulmonary edema (n=2, 5.1%). The patients who had respiratory problems showed a significantly higher mortality rate than those who did not have respiratory problems (66.6% versus 26.6%, respectively; P<.05). The overall mortality rate was 58.8% (20 patients). Thus, infectious and respiratory problems are the most frequent indications for admission and the most common problems during an ICU stay. The prognosis for patients who either have a respiratory problem upon admission to the ICU or develop one during the ICU stay is poor.

ABSTRACT: In this study we present our new technique, which will simplify reconstruction of even a small-caliber ureter. Our transplantation team has performed 1523 renal transplantation since 1975. From 1975 to 1983, we performed 300 ureteroneocystostomies using the modified Politano-Leadbetter technique. Since 1983, the extravesical Lich-Gregoir technique was used in combination with temporary ureteral stenting in 1141 patients. After September 2003, we began a corner-saving technique. Eighty-two (62 living related, 20 cadaver) renal transplantations have been performed since September 2003. The mean recipient age was 32.2 +/- 10.9 years (range, 7 to 63). Mean donor age was 38.9 +/- 13.1 years. For ureteral reimplantation, a running suture is started from 3 mm ahead from the middle of the posterior wall and finished 3 mm afterward. After the last stitch, both ends of the suture material are pulled and the posterior wall of the ureter and bladder are approximated tightly. The anterior wall is sewn either with the same suture or another running suture. Since using this technique, we have not employed a double J or any other stent to prevent ureteral complications at the anastomosis side. We have seen only two (2.4%) ureteral complications. In conclusion, due to the low complication rate, we believe that our new technique is the safest way to perform a ureteroneocyctostomy.

ABSTRACT: Intoxication due to eating wild mushrooms presents with a variety of signs, ranging from mild diarrhea to severe organ failure. We present the case of an 11-year-old boy with fulminant liver failure and hepatic coma due to Amanita phalloides poisoning treated with an urgent pediatric orthotopic liver transplantation. Successful treatment of patients with fulminant liver failure and hepatic coma caused by Amanita phalloides poisoning is possible using urgent orthotopic liver transplantation when conservative medical treatment modalities are ineffective.

ABSTRACT: Liver transplantation is the only curative treatment option for patients with cirrhosis and unresectable hepatocellular carcinoma (HCC) without extrahepatic dissemination. Criteria for transplantation in HCC are controversial. In this study, we evaluate the early results of liver transplantation for unresectable HCC. Between 2003 and 2004, 10 patients (three woman, seven men; aged 1.1 to 64 years) with occult or incidental HCC underwent liver transplantation. The inclusion criteria (independent of tumor size and number of tumor nodules) were: no invasion of major vascular structures and no evidence of extrahepatic disease, including that based on hilar lymph node biopsy and cytopathological examination of intraperitoneal fluid. Eight patients (80%) received tacrolimus and two patients (20%) received rapamycin monotherapy with early withdrawal of the corticosteroid. Four patients had neoadjuvant chemoembolization before transplantation. None of the patients received adjuvant chemotherapy. Two patients with hepatitis B virus cirrhosis underwent antiviral prophylaxis with anti-HBs antibody and lamivudine. During follow-up (range, 8 to 19 months), all patients did well with excellent graft function. There was no evidence of tumor recurrence on imaging studies, and there were no elevations in alpha fetoprotein or carcinoembryonic antigen levels. Low-dose immunosuppression and expanded criteria for liver transplantation for HCC appear to have beneficial effects on disease recurrence and patient outcomes, especially in regard to living donation.

ABSTRACT: The aim of this study was to compare incidence rates of mechanical and infectious complications associated with central venous catheterization via the internal jugular vein (IJV) versus the subclavian vein (SV) among 45 consecutive patients undergoing orthotopic liver transplantation (OLT) between January 2000 and June 2004. The subjects were divided into two groups according to the site of central venous catheterization (IJV or SV). We recorded each patient's physical characteristics, international normalized ratio (INR), partial thromboplastin time, platelet levels, number of puncture attempts, success/failure of central venous catheterization, duration of catheter placement, occurrence of catheter tip misplacement, arterial puncture, incidence of hematoma or pneumothorax, catheter-related infection, or bacterial colonization of the catheter. Senior staff anesthesiologists performed 22 SV and 23 IJV catheterizations for the 45 OLT procedures. The SV and IVJ groups both had minor coagulation abnormalities with slightly increased INR values at the time of catheterization. There were no significant differences between the groups with respect to success of central venous catheterization (100% for both), numbers of attempted punctures, duration of catheter placement, and incidence rates of mechanical and infectious complications. Both groups showed high frequencies of catheter tip misplacement, with right atrium as the site of misplacement in all cases. Two patients in the IJV group (8.7%) developed hematomas after accidental carotid artery puncture. The results suggest that, when performed by experienced anesthesiologists, central venous catheterization via the SV is an acceptable alternative to IJV catheterization for patients undergoing OLT.

ABSTRACT: Vascular complications are the major cause of morbidity and mortality after liver transplantation, particularly in pediatric patients, owing to their smaller vascular diameters. Between September 2001 and June 2004, among 21 (16 boys and 5 girls) pediatric liver transplantations of mean age 8.3 +/- 5.1 years, hepatic arterial thrombosis (HAT) was diagnosed in 2 (9.5%) patients, and hepatic arterial stenosis (HAS) in 4 (19.4%). Vascular patency was evaluated with Doppler ultrasonography every 12 hours in the first postoperative week and daily in the second postoperative week. When occlusion was suspected, conventional angiography was performed. Thrombectomy was performed in one patient, and thrombectomy and reanastomosis were performed in another patient with HAT. Two patients with HAS were treated with balloon angioplasty. A third patient was treated with balloon angioplasty and endoluminal stent placement at the same time. The last patient with HAS had an intimate dissection, which occurred 24 hours after balloon angioplasty, that was treated with subsequent endoluminal stent placement. Mean follow-up for the patients with vascular complications was 9.5 +/- 5.7 months (range, 4 to 18 months). The overall mortality rate was 14.1% (3/21); however, no deaths were caused by vascular complication. Routine Doppler ultrasonographic evaluation is an effective choice for diagnosing vascular complications seen after liver transplantation. Immediate surgical intervention is required for acute vascular complications, whereas late complications may be treated with balloon angioplasty and/or endoluminal stent placement.

ABSTRACT: Anesthetic management of orthotopic liver transplantation (OLT) in pediatric patients is challenging in terms of intraoperative bleeding, fluid management, and hemodynamic monitoring. The pulse contour cardiac output (PiCCO) system, a relatively new device based on the single-indicator transaortic thermodilution technique, may be useful for intraoperative hemodynamic monitoring in pediatric patients. This is a preliminary report of PiCCO use in nine children (aged 9.8 +/- 4.7 years) undergoing OLT. Hemodynamic volumetric parameters monitored by the PiCCO system were mean arterial pressure (MAP), cardiac index (CI), intrathoracic blood volume index (ITBVI), extravascular lung water index (EVLWI), systemic vascular resistance index (SVRI), and stroke volume variability (SVV). All parameters were recorded at anesthesia induction (T0), at the end of the anhepatic phase (Tanhepatic), and at the end of operation (Tend). The PiCCO system revealed similar MAP, CI, EVLWI, SVV, and SVRI values at all measurement intervals. Despite similar central venous pressure measurements, ITBVI values indicated significantly lower values at Tanhepatic than at T0 (627 +/- 160 mL/m2 and 751 +/- 151 mL/m2, respectively, P = .013). There were no PiCCO catheter-related complications in any patient. These findings demonstrate that the PiCCO system is a safe, continuous, multiparameter invasive monitoring device for use in pediatric patients undergoing OLT. This system may provide valuable data during pediatric OLT and appears to be a promising monitoring tool in these patients.

ABSTRACT: Living-donor renal transplantation has become common worldwide. However, living-donor nephrectomy is not a complication-free procedure. This retrospective study reviews the intra-and postoperative risks and complications of donor nephrectomies at our institution between 1994 and 2002.
Two hundred fifty-seven consecutive donor nephrectomy patients were evaluated using medical records and anesthetic charts.
The mean age of living donors was 42 +/- 12 years: 19 were older than 61 years, and 143 (55.6%) were women. Anesthesia for donor nephrectomy included general anesthesia, combined spinal-epidural anesthesia (CSE), general + CSE, and general + epidural anesthesia. We observed 51 intra- and postoperative complications in 26 patients. The minor complication rate was 10.1%. The duration of surgery was 3.56 +/- 0.26 hours (range, 2 to 5 hours). Serum creatinine levels were increased significantly (P < .05) on postoperative days 1, 3, and 5 compared with the preoperative levels (P < .05). There was no mortality.
Like other surgical operations, living-donor nephrectomy is associated with intra- and postoperative complications. Although these complications are minor, maximal efforts must be applied in the anesthetic approach to minimize donor complications, and donors should be informed about potential risks.

ABSTRACT: General and regional anesthesia may both be used successfully in donor nephrectomy although the use of regional anesthesia is rare. We compared the remaining kidney function during general (n = 10) versus combined spinal-epidural (n = 10) anesthesia for donor surgery. Blood biochemistry data were collected preoperatively and postoperatively, while renal function was assessed by scintigraphy and urine levels of microalbumin, creatinine, Na, K, Ca and creatinine clearance rate were measured/calculated in 24-hour urine samples collected preoperatively and on postoperative day 2. There were no differences preoperatively and on postoperative day 2 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P > .05 for all). There were also no differences between the groups with respect to other scintigraphic findings preoperatively and on postoperative day 2 (P > .05 for all). The results suggest that general or combined spinal-epidural anesthesia for donor nephrectomy have similar effects on the remaining donor kidney function.

ABSTRACT: Various general and regional anesthesia methods are used successfully in living-donor kidney transplantation. This study compared kidney graft function after general versus combined spinal-epidural anesthesia for donor nephrectomy. The study groups included recipients who received grafts from donors who had undergone nephrectomy under general anesthesia (GA group; n=10), and recipients who received grafts from donors who had combined spinal-epidural anesthesia (CSE group, n=10). Standard continuous epidural anesthesia was administered during all transplantations. Graft function was assessed using scintigraphy and Doppler ultrasonography on days 3 and 7. Urine levels of microalbumin, creatinine, and creatinine clearance rate were measured/calculated in 24-hour urine samples collected on postoperative days 3 and 7. There were no differences on either day 3 or day 7 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P >.05 for all). There were also no differences between the groups with respect to other scintigraphic findings on day 3 or day 7 (P >.05 for all). Ultrasonography on day 7 showed significantly higher mean peak systolic flow in the main renal artery in the CSE group than in the GA group (P=.035). The results suggest that GA and CSE for donor nephrectomy have similar effects on kidney graft function in recipients.
