    ABSTRACT: Laparoscopic live donor nephrectomy is becoming the procedure of choice for kidney procurement. In the course of 172 laparoscopic procurements, degloving of the renal capsule, a rare complication believed to be related to the method of extraction of the kidney, was encountered in 2 patients (1.2%). The complication was noted after revascularization of the kidney. A capsulotomy was performed to evacuate the subcapsular hematoma. No adverse effect was noted in the postoperative period in the transplanted kidneys.

    ABSTRACT: Since the introduction of the laparoscopic live donor nephrectomy in 1995, attempts have been made to depart from the total laparoscopic approach to the hand-assisted approach to decrease surgical time and complications. We present our 6-year experience with the total laparoscopic approach. Between December 1998 and November 2004 there were 168 total laparoscopic live donor nephrectomies performed at our institution. There were 163 left nephrectomies and 5 right nephrectomies. The procedure was performed in a systematic approach. The surgical time deceased from an average of 2:27 hours in the first year to 1:34 hours in the last year of the study. The overall average warm ischemia time was 3.5 minutes. Major bleeding requiring conversion to an open procedure occurred in 2 (1.2%) donors. Minor bleeding that was controlled laparoscopically occurred in 9 (5.4%) donors. Degloving of the renal capsule occurred in 2 (1.2%) donors with no consequences. Minor mesenteric rent occurred in 7 (4.2%) donors. All mesenteric complications were recognized and repaired laparoscopically. No ureteral or bowel injuries occurred. There were no mortalities. Eighty-three percent of donors were discharged the next day. Total laparoscopic live donor nephrectomy is safe. It was performed successfully in 98.8% of donors with a short surgical time, low morbidity, and 0% mortality.

    ABSTRACT: It has been demonstrated that graft survival rates of offspring-to-mother and husband-to-wife renal transplants are equivalent to those of other living donors. Although the vast majority of these transplants proceed without incident, we have encountered several instances of delayed accelerated rejections that are not predicted by a positive cross-match. The accelerated rejection can result from an anamnestic reaction subsequent to the in utero exposure of the mother to human leukocyte antigen (HLA) antigens of the fetus with sensitization developing during the pregnancy.

    ABSTRACT: Between June 1999 and November 2001 a prospective study was conducted to evaluate the effects of pneumoperitoneum during laparoscopic donor nephrectomy on kidney function using two different pressure settings (15 and 10 mm Hg). The effects were evaluated in both the donor's remaining kidney and the procured kidney in the recipient. There was no statistical significant difference in donors and recipients in regard to age, gender, and body mass index. In the two donor groups there was no difference in operative time (2.77 +/- 0.51 vs 2.70 +/- 0.52 hours; P = 0.579), intraoperative fluid (16.53 +/- 4.72 vs 19.54 +/- 7.04, P = 0.056), and urine output (1.81 +/- 0.53 vs 1.75 +/- 0.96 mL/kg/hour, P = 0.782) respectively. Donors' preoperative and first-day postoperative serum creatinine concentrations also did not differ for the groups (preoperative 0.87 +/- 0.21 vs 0.88 +/- 0.17 mg/dL; and postoperative 1.44 +/- 0.32 vs 1.38 +/- 0.29 mg dL, respectively; P = 0.696). Recipients' preoperative and postoperative serum creatinine concentrations on days 1, 2, 3, 7, 14, and 30 differed over time (P < 0.001) but not between groups (P = 0.541). We conclude that procurement of kidneys under either 10 or 15 mm Hg abdominal pressure gives equally good intraoperative and postoperative results.

    ABSTRACT: Recently, laparoscopic harvesting of kidneys from live donors has been reported by major university centers. As a community transplant center, we adopted a multidisciplinary cooperative approach, including a full-time transplant surgeon, a laparoscopic general surgeon, and a urologist with laparoscopic experience, in order to perform our first successful laparoscopic live donor nephrectomy in December 1998. The operative time was 234 minutes, and the warm ischemia time was 2 minutes. No intraoperative or postoperative complications occurred. The length of the renal artery was 2.4 cm, the renal vein was 3.0 cm, and the ureter was 10.0 cm. The donor was discharged home the next day and returned to work within 14 days. The transplanted kidney functioned immediately. The recipient serum creatinine concentration dropped from 9.3 mg/dL preoperatively to 3.4 mg/dL within 24 hours and to 1.3 mg/dL on the third day.
