- Abstract
Background: The robot-assisted laparoscopic approach for radical prostatectomy (RARP) is being performed increasingly worldwide to treat localized prostate cancer (PCa). The aim of this study was to compare the learning curves of two surgeons with different surgical experiences., Methods: A prospective collection of peri-operative data was made: age, body mass index, PSA, clinical stage, biopsy Gleason score, operative time (OT), blood loss (BL), pathological stages, final Gleason scores, and complications. Patients were included, in two groups. The first group comprised the first 100 patients undergoing RARP by an expert laparoscopic surgeon. The second group of 100 patients was operated on by a junior surgeon without robotic console experience. Post-operative complications were defined according to the Clavien grading system for surgical morbidity, Results: For groups 1 and 2 median age was 63 and 62 years, respectively; median pre-operative PSA level was 10 and 8, respectively; the median BMI was 24 and 25, respectively. The median operative time (OT) was 179 and 160 min, respectively (p > 0.05); and median blood loss was 217 and 346 ml, respectively (p = 0.04). The overall transfusion rate was 1.5% and two major complications were recorded in group 1 and four in group 2., Conclusions: RARP is safe and reproducible even during the initial learning curve. Overcoming the learning curve is multifactorial and is necessarily dependent on the surgeon. However, joining a well-trained team probably affects positively the performance of the surgeon. The value of expert centers to train new surgeons to RARP needs to be evaluated., (Copyright © 2011 John Wiley & Sons, Ltd.)

- Abstract
Background: A robot-assisted laparoscopic approach for radical prostatectomy (RALRP) is being adopted increasingly worldwide for the treatment of localized prostate cancer (CaP). Complications assessment is essential to the objective evaluation of any new procedure. This study aimed to assess the perioperative complications encountered during the implementation of a robot-assisted urologic surgery program., Methods: A prospective data collection for all men with a diagnosis of CaP who underwent RALRP between 2005 and 2009 in our department was achieved. Together with perioperative data, all the perioperative complications encountered were specifically recorded, including robot dysfunctions. The RALRP was performed with the three-arm Da Vinci system using a transperitoneal approach with six ports. To assess the perioperative complications, the validated Clavien-Dindo classification of surgical procedures was used. Two surgeons were involved in these procedures. A modified Clavien-Dindo classification also was used to account for intraoperative complications., Results: According to the Clavien-Dindo classification, 16 complications (6.7% complication rate) were recorded during the first 240 procedures. Besides postoperative complications, five procedures (2.1%) were directly affected by robot malfunctions without notable consequences for the patients. Considering these five additional complications, an 8.8% complication rate was recorded using a modified Clavien-Dindo classification. The main limitation of the study was its design restricted to RALRP procedures alone. The second limitation was that the authors' modified classification needs to be validated with a larger series and for different surgical procedures., Conclusions: The findings show that RALRP is a safe alternative to classical surgery and that the robotic approach is reliable. The authors believe that the reliability of technological devices should be systematically discussed when outcome analysis of a new procedure is performed.

- Abstract
The management of ureteropelvic junction (UPJ) obstruction has evolved over the past 20 years in response to the development of new technology. Open surgery is still the reference standard against which all other surgical interventions must be measured. The surgical approach has, however, gone through rapid changes, and the open procedure initially described has evolved considerably. Endoscopic and laparoscopic approaches have largely supplanted open pyeloplasty for the majority of primary ureteropelvic junction obstruction cases. Laparoscopic approaches provide a balance between a highly successful technique in all patients and improved postoperative recovery. It has been shown to improve postoperative outcomes with shorter recovery times and hospital stays, and to provide equivalent functional results with a success rate of 95%. Nevertheless, laparoscopic pyeloplasty is not a simple procedure. There are a certain number of disadvantages, such as the limited range of laparoscopic instrument movement, the two dimensional image, the unfamiliar hand-eye coordination and the relatively inefficient ergonomic position. Since 2000, however, robots have provided a magnified three-dimensional view giving a greater degree of freedom. This system has simplified suturing and has improved precision of the operating technique. However, the system is very expensive and, providing it is available in their institution, it seems easier for beginners to learn the robotic technique. Additionally, it has similar success rates (both radiological and clinical) to those obtained with open techniques.

- Abstract
Purpose: To assess the effectiveness of robot-assisted pyeloplasty in patients with clinically symptomatic ureteropelvic junction obstruction (UPJO)., Patients and Methods: We retrospectively reviewed our database for all patients who were treated for UPJO by a single surgeon using a robot-assisted procedure between 2005 and 2007. We collected the following: Patient age, clinical presentation, perioperative data, complications, length of hospital stay, and outcome. Preoperative evaluation of UPJO always included an injected renal CT scan and furosemide-mercaptoacetyltriglycine (MAG-3) renal scintigraphy. Patients were seen at 3 and 6 months after surgery and once a year thereafter. Postoperative success was defined as symptomatic response and radiographic evidence of no further obstruction., Results: Twenty patients with a mean age of 36.8 +/- 16 years (range 15-69 yr) were included. Six (30%) patients had previously undergone endoscopic treatment. The mean operative time was 150.3 +/- 36.22 minutes (range 150-240 min). The mean follow-up was 19.9 +/- 10.03 months (range 3-37 mos). Two (10%) procedures necessitated conversion to laparoscopic procedures, and there was no conversion to laparotomy. Four (20%) patients experienced minor complications: Two urinary tract infections and two urinomas. Repeated early surgery was needed in one patient for temporary (ie, 8 days) stent placement in the case of urinoma. There was no recurrence of the UPJO, and no repeated surgery was deemed necessary during the follow-up period. The success rate was estimated to be 95%., Conclusions: Functional outcomes after robot-assisted procedures for alleviation of UPJO are very promising. Our data showed that the robot-assisted procedure was safe and featured negligible morbidity. Therefore, we conclude that our approach is a viable alternative to open surgery.

- Abstract
The study was performed to determine factors affecting successful sperm retrieval by testicular sperm extraction in patients with nonmosaic Klinefelter's syndrome (KS). From May 2001 to February 2007, 27 azoospermic patients were diagnosed as having nonmosaic KS. All patients underwent sperm testicular extraction. Patient's age, testicular volume, serum follicle-stimulating hormone (FSH) and inhibin B were assessed as predictive factors for successful sperm recovery. Of the 27 Klinefelter's patients examined, eight (29.6%) had successful sperm recovery. The comparisons of serum FSH, inhibin B and testicular volume between patients with and without successful sperm retrieval did not show any statistical significance. The patients with successful sperm recovery were significantly younger (28.6 +/- 3.11 years) than those with failed attempts (33.9 +/- 4.5 years, P = 0.002). The rate of positive sperm retrieval was significantly higher in patients younger than 32 years compared with patients older than 32 years (P = 0.01, chi-squared test). The study showed that clinical parameters such as FSH, inhibin B and testicular volume do not have predictive value for sperm recovery in patients with KS. The mean age of our patients with successful sperm recovery was significantly lower than that of men with unsuccessful results. Testicular sperm extraction or testicular sperm aspiration should be performed before the critical age of 32 years.
