    ABSTRACT: Partial nephrectomy is currently the standard treatment for clinical T1 renal neoplasms, as it can provide oncologic outcomes equivalent to radical nephrectomy. The aim was to evaluate the efficacy of self-retaining suture (SRS) in renorrhaphy technique in retroperitoneal laparoscopic partial nephrectomy (LPN) for a single renal mass of moderate or high complexity by assessing peri-operative outcomes. A retrospective analysis was done of 64 patients between 2010 and 2012 for complex renal mass (RENAL score ≥7) in whom retroperitoneal LPN was performed with two layers using continuous knotless barbed suture (Quill PDO SRS group; n = 34) and absorbable vicryl (non-SRS group; n = 30), respectively. Cases were matched for RENAL score. All the surgical procedures were performed by the same surgeon with experience of more than 500 cases of LPN. Comparisons were made in patients and preoperative outcomes and peri-operative complications between SRS group and non-SRS group. Mean warm ischemia time (WIT) in SRS group was less than non-SRS group (18.0 vs. 24.8 minutes, P = 0.021). Renorrhaphy suture cost in SRS group was lower than non-SRS group ($269.6 vs. $335.8, P = 0.001). There were no significant differences between the two groups for postoperative changes in creatinine and estimated glomerular filtration rate and the rate of peri-operative complications. SRS was safe for complex renal tumor with two layers, continuous and unknot suture, during LPN and would reduce the WIT and renorrhaphy suture cost significantly.

    ABSTRACT: The aim of this study was to validate the advantages of the intrafascial nerve-sparing technique compared with the interfascial nerve-sparing technique in extraperitoneal laparoscopic radical prostatectomy. From March 2010 to August 2011, 65 patients with localized prostate cancer (PCa) underwent bilateral intrafascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy. These patients were matched in a 2∶1 ratio to 130 patients with localized PCa who had undergone bilateral interfascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy between January 2008 and August 2011. Operative data and oncological and functional results of both groups were compared. There was no difference in operative data, pathological stages and overall rates of positive surgical margins between the groups. There were 9 and 13 patients lost to follow-up in the intrafascial group and interfascial group, respectively. The intrafascial technique provided earlier recovery of continence at both 3 and 6 months than the interfascial technique. Equal results in terms of continence were found in both groups at 12 months. Better rates of potency at 6 months and 12 months were found in younger patients (age ≤65 years) and overall patients who had undergone the intrafascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy. Biochemical progression-free survival rates 1 year postoperatively were similar in both groups. Using strict indications, compared with the interfascial nerve-sparing technique, the intrafascial technique provided similar operative outcomes and short-term oncological results, quicker recovery of continence and better potency. The intrafascial nerve-sparing technique is recommended as a preferred approach for young PCa patients who are clinical stages cT1 to cT2a and have normal preoperative potency.Asian Journal of Andrology advance online publication, 27 May 2013; doi:10.1038/aja.2012.157.

    ABSTRACT: The oncological and functional results of 329 cases in a population treated with extraperitoneal laparoscopic radical prostatectomy (ELRP) were evaluated retrospectively. A total of 329 inconsecutive patients with prostate cancer (PCa) who underwent ELRP were retrospectively analyzed. The median initial prostate-specific antigen (PSA) level was 17.35 ng/ml. The median biopsy Gleason score was 7.77. Patients with a T2 or T3a clinical stage had received preoperative neoadjuvant hormonal therapy (NHT) for 3 to 9 months prior to ELRP. No conversion or re-intervention were observed. The median time for anastomosis, surgery time and postoperative catheterization time were 13.0 min, 90.0 min and 6 days, respectively. The median estimated blood loss was 75 ml. There were 12 temporary urinary leakages requiring prolonged catheterization to 14 days. There was 1 case of deep vein thrombosis, 1 case of alimentary tract hemorrhage and 7 cases of anterior urethral stricture. The median follow-up time was 27 months. A total of 17 patients were lost during the follow-up period. No rectal injury, lymphocele, incision hernia, postoperative persistent urinary leak or anastomotic stricture occurred. Younger patients (≤67 years of age) had a more rapid recovery of continence and a better postoperative potency. The overall positive surgical margin rate was 16.7%, which correlated with the pathological stage and Gleason score, respectively (both P<0.001). A total of 89 (28.6%) patients were diagnosed with biochemical recurrence. The initial PSA value, PSM, pathological stage and Gleason score were identified as independent prognostic factors for biochemical recurrence-free survival using multivariate analysis. Our results demonstrated that preoperative NHT had significant effects on the pathological Gleason score (P<0.001) and surgical margin (P=0.027), but no significant impact on biochemical recurrence (P=0.202). The reproducibility of ELRP has been proven as a reliable curative treatment in Western countries during the last 15 years. Due to the increase in PCa patients, the results of our study may aid surgeons who use ELRP for the first time.

    ABSTRACT: Purpose: The purpose of this study was to introduce a new method for locating the renal artery during retroperitoneal laparoscopic renal surgery. Patients and methods: The medial arcuate ligament (MAL) is a tendinous arch in the fascia under the diaphragm that arches across the psoas major muscle and is attached medially to the side of the first or the second lumbar vertebra. The renal artery arises at the level of the intervertebral disc between the L1 and L2 vertebrae. We evaluate the role of the MAL that serves as an anatomic landmark for locating the renal artery during retroperitoneal laparoscopic renal surgery. Results: There is a reproducible consistent anatomic relationship between MAL and the renal artery in 210 cases of retroperitoneal laparoscopic renal surgery. Two main types of the MAL, the "narrow arch" and the "fascial band" types, can be observed. Conclusion: MAL can serve as an accurate and reproducible anatomic landmark for the identification of the renal artery during retroperitoneal laparoscopic renal surgery.

    ABSTRACT: Laparoscopic adrenalectomy has become the gold-standard for the surgical treatment of most adrenal lesions. This study evaluated the operative outcome of laparoendoscopic single-site (LESS) retroperitoneoscopic adrenalectomy (LESS-ARA) in comparison with the current standard operation procedure. Between June and December 2009, 19 patients underwent LESS-ARA, and their outcomes were compared with a contemporary 1:2 matched-pair cohort of 38 patients who underwent standard ARA by the same surgeon. In LESS-ARA, a multichannel port was inserted through a 2.5- to 3.0-cm transverse skin incision below the tip of the 12th rib. The LESS-ARA procedure was performed using a 5-mm 30º laparoscopic camera and two standard laparoscopic instruments. The following parameters were compared between the two groups: demographics, details of the surgery, perioperative complications, postoperative visual analog pain scale score, analgesic requirement, and short-term measures of convalescence. The finding showed that LESS-ARA and standard ARA were comparable in terms of the estimated blood loss (30 vs 17.5 ml; p=0.64), postoperative hospital stay (6 vs 6 days; p=0.67), and postoperative complications (2 vs 3 patients; p=1.00) for patients with similar baseline demographics and median tumor size (2.1 vs 3.0; p=0.18) cm. The intraoperative hemodynamic values were similar in the two groups. The LESS-ARA group had a longer median operative time (55 vs 41.5 min; p=0.0004), whereas the in-hospital use of analgesics was significantly less (5 vs 12 morphine equivalents; p=0.03). The LESS retroperitoneoscopic adrenalectomy approach is feasible and offers a superior cosmetic outcome and better pain control, with perioperative outcomes and short-term measures of convalescence similar to those of the standard approach, albeit with a longer operative time.

    ABSTRACT: To present our surgical techniques and experience with retroperitoneal laparoscopic upper pole nephroureterectomy for a duplex kidney in adult patients without vesicoureteral reflux. A total of 32 adult patients with a duplex kidney underwent laparoscopic upper pole nephroureterectomy. A 3-port, finger- and balloon-dissecting, retroperitoneal approach was used. The upper pole renal parenchyma was divided circumferentially between the upper and lower poles using a harmonic scalpel, maintaining a margin around the upper pole parenchyma to avoid any possible injury to the lower pole functioning moiety. The urothelium of the remnant upper pole parenchyma was stripped off, and the edges of the remnant upper pole parenchyma were approximated with figure-of-8 stitches. The distal upper pole ureter was mobilized and transected at the point at which the ureter crossed anterior to the iliac vessels. Intravenous urography and renal ultrasonography were performed at 3 and 6 months postoperatively. All laparoscopic operations were performed successfully without conversion to open surgery. The mean operative time was 83 minutes. The mean blood loss was 18 mL. The mean postoperative hospital stay was 7 days. No intraoperative or major postoperative complications occurred. The intravenous urography and renal ultrasound findings 3 and 6 months postoperatively demonstrated normal pyelography findings and renal function of the preserved lower pole in all patients. Retroperitoneal laparoscopic upper pole nephroureterectomy is a safe and effective procedure and an excellent minimally invasive treatment option for the adult patient with a duplex kidney.

    ABSTRACT: The indication for laparoscopic total or partial adrenalectomy in patients with aldosterone producing adrenal adenoma remains controversial. We compared retroperitoneoscopic partial and total adrenalectomy for aldosterone producing adrenal adenoma in a prospective, randomized, multicenter trial. Patients with aldosterone producing adrenal adenoma were randomized to retroperitoneoscopic partial or total adrenalectomy. Patient characteristics, surgical data, complications and postoperative clinical results were analyzed statistically. From July 2000 to March 2004, 212 patients were enrolled in this study, including 108 and 104 who underwent total and partial adrenalectomy, respectively. The 2 groups were comparable in patient age, gender, body mass index and tumor site. Mean followup was 96 months in each group. No conversion to open surgery was needed and no major complications developed. Partial adrenalectomy required a shorter operative time than total adrenalectomy but this did not attain statistical significance. Intraoperative blood loss in the partial adrenalectomy group was significant higher than in the total adrenalectomy group (p <0.05) but no patient needed blood transfusion. All patients in each group showed improvement in hypertension, and in all plasma renin activity and aldosterone returned to normal after surgery. No patient required potassium supplements postoperatively. In the total and partial adrenalectomy groups 32 (29.6%) and 29 patients (27.9%), respectively, were prescribed a decreased dose of or fewer antihypertensive medicines at final followup. Retroperitoneoscopic partial adrenalectomy is technically safe. It has therapeutic results similar to those of total adrenalectomy in patients with primary aldosteronism due to aldosteronoma.

    ABSTRACT: To our knowledge we present the initial experience with and the short-term outcome of laparo-endoscopic single site anatomical retroperitoneoscopic adrenalectomy using conventional instruments. Between June 2009 and April 2010, 25 patients underwent laparo-endoscopic single site anatomical retroperitoneoscopic adrenalectomy. A TriPort™ Access System was inserted through a 2.5 to 3.0 cm transverse skin incision below the tip of the 12th rib. Adrenalectomy was done using a 5 mm 30-degree laparoscopic camera and 2 conventional laparoscopic instruments. After Gerota's fascia was incised we explored the first dissection plane between the perirenal fat and the anterior renal fascia at the superomedial side of the kidney. The adrenal gland was identified at the initial stage of the operation. Laparo-endoscopic single site anatomical retroperitoneoscopic adrenalectomy was successfully accomplished in 23 patients. An additional 5 mm port was required in 1 of the 2 unsuccessful cases and in the other it was necessary to convert to standard anatomical retroperitoneoscopic adrenalectomy. Median incision length was 3.0 cm, median operative time was 55 minutes and median estimated blood loss was 15 ml. No major intraoperative complications occurred. In the initial 10 cases median operative time was significantly longer (62 vs 50 minutes) and median blood loss was significantly higher (75 vs 10, each p <0.001) than in the subsequent 15. In 3 cases pheochromocytoma was successfully excised without undesirable hemodynamic oscillation. Postoperative complications developed in 2 patients, including angina and contralateral atelectasis in 1 each. In properly selected patients laparo-endoscopic single site anatomical retroperitoneoscopic adrenalectomy with conventional instruments is feasible, safe and effective, causes minimal morbidity and results in excellent cosmesis.

    ABSTRACT: To present our surgical techniques and experience with retroperitoneal laparoscopic ureteroureterostomy in 10 patients with retrocaval ureter and review the data on the laparoscopic management of retrocaval ureter published in English. A total of 10 patients with retrocaval ureter underwent laparoscopic ureteroureterostomy. A 3-port, finger and balloon-dissecting, retroperitoneal approach was used. The retrocaval segment of ureter was mobilized and transposed anterior to the inferior vena cava. The ureteroureteral anastomosis was completed with the intracorporal freehand suturing and in situ knot tying techniques. Intravenous pyelography was performed 3 and 6 months, postoperatively. Thereafter, intravenous pyelography follow-up was then continued at 12-month intervals for 3 years, and yearly renal ultrasonography follow-up was continued for at least 2 years. A comprehensive electronic English-language literature search of PUBMED was conducted. All operations were completed laparoscopically without conversion to open surgery. The mean operative time was 82 minutes (range, 60-110 minutes). The blood loss was minimal (< 10 mL). No perioperative complication occurred. All patients achieved an uneventful recovery. At a mean follow-up of 52 months, remarkable improvement in the ureteral obstruction was observed. Data of 19 patients in 12 published English-language literatures were reviewed. Our results indicate that retroperitoneal laparoscopic ureteroureterostomy is a safe and effective procedure, and an excellent minimally invasive treatment option for retrocaval ureter. Moreover, a thorough review of published data supports our viewpoint that laparoscopic surgery should probably be the first-line treatment for retrocaval ureter.

    ABSTRACT: To study the effect on promoter de-methylation, expression of ALDH1a2 gene and cell apoptosis by treated with 5-Aza-dC and TSA in five human bladder cancer cell lines. Human bladder cancer cell lines RT-4, 253J, 5637, BIU-87 and T24 were cultured and treated with 5-Aza-dC and(or) TSA. The expression of the ALDH1a2 gene was detected by RT-PCR and Western blot. The methylation status of gene promoter was determined by MSP, and the cell cycle profile was established by flow cytometry. ALDH1a2 was silenced in five human bladder cancer cell lines. Re-expression of ALDH1a2 was detected after treated with 5-Aza-dC alone or TSA in combination. ALDH1a2 transcript was marked in each cell lines combined with 5-Aza-dC and TSA treatment which showed a synergistic effect on expression of ALDH1a2 transcript. Early apoptotic was the main mode of apoptosis and death of human bladder cancer cell lines induced by 5-Aza-dC and TSA. The percentage of early apoptotic cells was 1.4% in control group and 2.8% in TSA group, however, 20.2% in 5-Aza-dC group and 33.8% in 5-Aza-dC + TSA group, respectively. The groups of TSA, 5-Aza-dC and 5-Aza-dC + TSA were significantly different from control group (P < 0.05). Aberrant methylation of ALDH1a2 gene is the main cause for gene transcriptional inactivation. Re-expression of ALDH1a2 gene and cell apoptosis are detected after either treatment with 5-Aza-dC alone or in combination with TSA.

    ABSTRACT: To develop a new porcine model with horn of the uterus to mimic an enlarged ureter for training for laparoscopic ureteral reimplantation (LUR) and to evaluate its feasibility. Ten female pigs were used in the training. The pig was placed to a dorsal position after an anesthetic was administered. The horn of the uterus near the bladder was dissected, then spatulated and trimmed to replace the enlarged ureter. LUR was performed according to standard operation steps. Four trainees completed the LUR procedure based on a mentor-trainee model to guarantee the success of the procedure and the quality of the anastomoses. The learning curve of operative time was analyzed. The anastomotic stoma was cut off postoperatively and checked extracorporeally. After the course, questionnaire surveys were sent to the trainees to investigate satisfaction of the training and assess the impact of the training on their learning of "real" LUR in future practice. This model reproduced the key technique steps of LUR. Four LUR procedures were performed on each pig. The operative time declined from 170.0 +/- 10.3 minutes to 90.3 +/- 3.7 minutes (P < 0.01) after the trainees had performed 10 LURs. There was proper stitching in each "ureterovesical" anastomosis. At the end of training, all trainees could accomplish a LUR procedure skillfully on the model; they were satisfied after the course and thought the training was helpful to future practice of LUR. The new model was feasible and cost-effective for training in the basic skills of laparoscopic ureteral reconstruction procedures.

    ABSTRACT: The expression of fibulin-5 was investigated in urothelial carcinomas of bladder and in normal bladder samples. The effects of fibulin-5 on cell proliferation, motility, and invasion were further explored in bladder cancer cell line 5637. The expression of fibulin-5 in 20 bladder carcinoma samples and 7 normal bladder samples were detected by Western blot. Fibuin-5 cDNA was cloned into p-EGFP-N1 vector and transfected into bladder cancer cell line 5637. Growth curves were estimated by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide assay and cell number count. The migration and invasion of the transfected cells and the control cells were measured by Boyden chamber assay. Compared with 1.16 ± 0.28 in the normal control, the mean ± SD expression of fibulin-5 in low grade tumors and high grade tumors were 0.57 ± 0.32 and 0.44 ± 0.42 (P = 0.002 and P = 0.018, respectively), while the expression in Ta-T1 tumors and T2+ tumors were 0.55 ± 0.31 and 0.49 ± 0.43 (P = 0.002 and P = 0.015, respectively). The differences between low grade and high grade tumors or Ta-T1 and T2+ tumors were not statistically significant (P = 0.362 and P = 0.589, respectively). The growth rate of the fibulin-5 transfected GFP-F5 cells was remarkably reduced than that of the untransfected cells or the empty vector transfected GFP-t cells. Besides, compared with control cells, the GFP-F5 cells showed significant inhibition of cell invasion with slight inhibition of cell migration. Fibulin-5 is down-regulated in urothelial carcinoma of bladder and acts as a tumor suppressor gene by inhibiting proliferation and invasion of bladder cancer cells.

    ABSTRACT: We introduced a multimodal training program for laparoscopic pyeloplasty (LP) and evaluated its safety, feasibility, and efficacy. The program consisted of box-trainer training, animal-model training, and operative training. Five trainees with different experiences in open pyeloplasty and laparoscopy were exposed to the program. The mentor performed objective and subjective evaluations at each stage to ensure the training quality and operation safety. The perioperative parameters of five groups of patients who underwent LP by the trainees independently were evaluated. All trainees successfully finished the training program and independently performed five LPs under the supervision of the mentor. Five trainees spent different training times on the box-trainer and animal-model training,but acquired similar laparoscopic proficiency. There were no conversions to open procedures, transfusions, or deaths among the patients. No statistically significant difference was found in the operative time, estimated blood loss, postoperative hospital stay, and perioperative complications among the five trainees (P > 0.05). The multimodal training program can be used to train residents to perform advanced LP through step-by-step training from box trainer to animal model to clinical practice. The mentor-initiated approach is important to guarantee the training quality and safety.

    ABSTRACT: We investigated the expression of Notch receptors and ligands in normal bladder transitional epithelium and transitional cell carcinoma of the bladder. We also explored its clinical and pathological implications. The expression of Notch-1 to 3, Jagged-1 and Delta-like-1 was detected respectively in 70 cases of bladder carcinoma, 10 of normal urothelium and the 2 cell lines T24 and BIU-87 using immunohistochemistry. Reverse transcriptase-polymerase chain reaction and Western blot were used to assay the expression level of Notch-1 and Jagged-1. The predictive value of this expression for prognosis was investigated by Kaplan-Meier curves and Cox proportional hazards analysis in a multivariate model. All 5 kinds of Notch factors were intensively stained in normal bladder transitional epithelium immunohistochemically but expression was significantly decreased in tumor tissues. Moreover, expression of the 5 genes in papillary tumors was lower than in invasive tumors but only Notch-1 and Jagged-1 showed a statistically significant difference. Postoperative disease-free survival time in patients with low Notch-1 plus Jagged-1 expression was significantly shorter than that in patients with other expression patterns in papillary tumors (p = 0.014). Multivariate Cox proportional hazards model analysis identified Jagged-1 expression as an independent prognostic factor for disease-free survival (RR 3.09, p = 0.011). The Notch family expression pattern in papillary bladder transitional cell carcinoma is different from that in invasive bladder transitional cell carcinoma. Low expression of Notch-1 as well as Jagged-1 is potentially a useful marker for survival in patients with papillary bladder transitional cell carcinoma.

    ABSTRACT: To investigate the association between DNA polymorphisms, including single-nucleotide polymorphisms (SNPs) and insertion/deletion polymorphisms, in exon 1 and promoter of the CDH1 gene, and the risk of transitional cell carcinoma (TCC) of the urinary bladder (TCCB). This was a hospital-based case-control study of 180 patients with TCCB and 110 normal controls. Genomic DNA was extracted from blood samples of all participants and genotypes determined using polymerase chain reaction and DNA sequencing techniques. Haplotypes were analysed using appropriate software. SNPs were detected at -160A/C, -73A/C and 178C/T; an inserted oligonucleotide of 5'-CCGTGCCCCAGCC-3' was identified at 234 bp. The -160A allele frequency in the case group was 0.67, statistically higher than in the control group (0.42; P < 0.001), and higher in invasive carcinoma (0.77) than in superficial carcinoma (0.60). For -73C/A and 178C/T SNPs there was no difference among genotypes. The 234 repeat oligonucleotide insertion (2I) frequencies in cases was 0.27, statistically higher than in the control group (0.17; P = 0.01). The most common haplotype in controls was C-A-T-I (28%), the frequency of which was higher than in the TCCB group (6%). The A-A-T-2I was the only variation distribution carrying the -160A allele and was at a statistically higher frequency in the TCCB group (37%, the most common haplotype in cases) than in the control group. The -160A, 234 2I allele and haplotype A-A-T-2I were risk factors of TCCB. Haplotype C-A-T-I might act as a protective factor for TCCB.

    ABSTRACT: We compared the clinical outcomes of retroperitoneoscopic and open adrenalectomy for pheochromocytoma. Clinical data on 56 patients who underwent retroperitoneoscopic lateral adrenalectomy were retrospectively compared with those on 50 who underwent open adrenalectomy for pheochromocytoma, including patient demographic data, perioperative indexes and clinical outcomes. Demographic data on patients were similar in the 2 groups. In the retroperitoneoscopic group such perioperative indexes were significantly different from those of the open group (each p <0.05), including operative time (mean +/- SD 52 +/- 22 vs 120 +/- 42 minutes), estimated blood loss (74 +/- 34 vs 187 +/- 64 ml), resumption of oral intake (1 vs 2 days), postoperative hospital stay (5.2 +/- 1.7 vs 8.3 +/- 1.8 days), incidence of intraoperative hypertension (17.0% or 9 of 53 patients vs 36.0% or 18 of 50) and number of patients requiring blood transfusion(1.8% or 1 of 53 vs 16.0% or 8 of 50). The incidence of systemic inflammatory response syndrome was much less in the retroperitoneoscopic group (20.8% or 11 of 53 patients vs 42.0% or 21 of 50, p <0.05). However, the duration of systemic inflammatory response syndrome and postoperative complications were similar in the 2 groups (p >0.05). Blood pressure returned to normal 3 months after the operation in 81% of the patients in the retroperitoneoscopic group and in 84% in the open group. During the followup of 5 to 36 months no tumor recurrence and/or metastasis developed. Compared with open surgery retroperitoneoscopic lateral adrenalectomy for pheochromocytoma is a safe, minimally invasive and effective procedure.
