Technical solutions to improve the management of non-muscle-invasive transitional cell carcinoma: summary of a European Association of Urology Section for Uro-Technology (ESUT) and Section for Uro-Oncology (ESOU) expert meeting and current and future perspectives.

The aim of the present review was to compare state-of-the-art care and future perspectives for the detection and treatment of non-muscle-invasive transitional cell carcinoma (TCC) of the bladder. We provide a summary of the third expert meeting on 'Optimising the management of non-muscle-invasive bladder cancer, organized by the European Association of Urology Section for Uro-Technology (ESUT) in collaboration with the Section for Uro-Oncology (ESOU), including a systematic literature review. The article includes a detailed discussion on the current and future perspectives for TCC, including photodynamic diagnosis, optical coherence tomography, narrow band imaging, the Storz Professional Image Enhancement system, magnification and high definition techniques. We also provide a detailed discussion of future surgical treatment options, including en bloc resection and tumour enucleation. Intensive research has been conducted to improve tumour detection and there are promising future perspectives, that require proven clinical efficacy. En bloc resection of bladder tumours may be advantageous, but is currently considered to be experimental.

Extracorporeal shock wave lithotripsy: An opinion on its future.

The development of miniaturized nephroscopes which allow one-stage stone clearance with minimal morbidity has brought the role of shock wave lithotripsy (SWL) in stone management into question. Design innovations in SWL machines over the last decade have attempted to address this problem. We reviewed the recent literature on SWL using a MEDLINE/PUBMED research. For commenting on the future of SWL, we took the subjective opinion of two senior urologists, one mid-level expert, and an upcoming junior fellow. There have been a number of recent changes in lithotripter design and techniques. This includes the use of multiple focus machines and improved coupling designs. Additional changes involve better localization real-time monitoring. The main goal of stone treatment today seems to be to get rid of the stone in one session rather than being treated multiple times non-invasively. Stone treatment in the future will be individualized by genetic screening of stone formers, using improved SWL devices for small stones only. However, there is still no consensus about the design of the ideal lithotripter. Innovative concepts such as emergency SWL for ureteric stones may be implemented in clinical routine.

The past, present and future of minimally invasive therapy in urology: a review and speculative outlook.

INTRODUCTION: Twenty-five years of SMIT represents an important date. In this article we want to elaborate the development of minimally invasive surgery in urology during the last three decades and try to look 25 years ahead. MATERIAL AND METHODS: As classical scenarios to demonstrate the changes which have revolutionized surgical treatment in urology, we have selected the management of urolithiasis, renal tumour, and localized prostate cancer. This was based on personal experience and a review of the recent literature on MIS in Urology on a MEDLINE/PUBMED research. For the outlook to the future, we have taken the expertise of two senior urologists, middle-aged experts, and upcoming junior fellows, respectively. RESULTS: Management of urolithiasis has been revolutionized with the introduction of non-invasive extracorporeal shock wave lithotripsy (ESWL) and minimally invasive endourology in the mid-eighties of the last century obviating open surgery. This trend has been continued with perfection and miniaturization of endourologic armamentarium rather than significantly improving ESWL. The main goal is now to get rid of the stone in one session rather in multiple non-invasive treatment sessions. Stone treatment 25 years from today will be individualized by genetic screening of stone formers, using improved ESWL-devices for small stones and transuretereal or percutaneous stone retrieval for larger and multiple stones. Management of renal tumours has also changed significantly over the last 25 years. In 1988, open radical nephrectomy was the only therapeutic option for renal masses. Nowadays, tumour size determines the choice of treatment. Tumours >4 cm are usually treated by laparoscopic nephrectomy, smaller tumours, however, can be treated either by open, laparoscopic or robot-assisted partial nephrectomy. For patients with high co-morbidity focal tumour ablation or even active surveillance represents a viable option. In 25 years, imaging of tumours will further support early diagnosis, but will also be able to determine the pathohistological pattern of the tumour to decide whether the patient requires removal, ablation or active surveillance. Management of localized prostate cancer underwent significant changes as well. 25 years ago open retropubic nerve-sparing radical prostatectomy was introduced as the optimal option for effective treatment of the cancer providing minimal side-effects. Basically, the same operation is performed today, but with robot-assisted laparoscopic techniques providing 7-DOF instruments, 3D-vision and tenfold magnification and enabling the surgeon to work in a sitting position at the console. In 25 years, prostate cancer may be managed in most cases by focal therapy and/or genetically targeting therapy. Only a few patients may still require robot-assisted removal of the entire gland. DISCUSSION: There has been a dramatic change in the management of the most frequent urologic diseases almost completely replacing open surgery by minimally invasive techniques. This was promoted by technical realisation of physical principles (shock waves, optical resolution, master-slave system) used outside of medicine. The future of medicine may lie in translational approaches individualizing the management based on genetic information and focalizing the treatment by further improvement of imaging technology.

Introduction of organised mammography screening in Tyrol: results of a one-year pilot phase.

BACKGROUND: Efficiency and efficacy of organised mammography screening programs have been proven in large randomised trials. But every local implementation of mammography screening has to check whether the well established quality standards are met. Therefore it was the aim of this study to analyse the most common quality indices after introducing organised mammography screening in Tyrol, Austria, in a smooth transition from the existing system of opportunistic screening. METHODS: In June 2007, the system of opportunistic mammography screening in Tyrol was changed to an organised system by introducing a personal invitation system, a training program, a quality assurance program and by setting up a screening database. All procedures are noted in a written protocol. Most EU recommendations for organised mammography screening were followed, except double reading. All women living in Tyrol and covered by social insurance are now invited for a mammography, in age group 40-59 annually and in age group 60-69 biannually. Screening mammography is offered mainly by radiologists in private practice. We report on the results of the first year of piloting organised mammography screening in two counties in Tyrol. RESULTS: 56,432 women were invited. Estimated participation rate was 34.5% at one year of follow-up (and 55.5% at the second year of follow-up); 3.4% of screened women were recalled for further assessment or intermediate screening within six months. Per 1000 mammograms nine biopsies were performed and four breast cancer cases detected (N = 68). Of invasive breast cancer cases 34.4% were ≤ 10 mm in size and 65.6% were node-negative. In total, six interval cancer cases were detected during one year of follow-up; this is 19% of the background incidence rate. CONCLUSIONS: In the Tyrolean breast cancer screening program, a smooth transition from a spontaneous to an organised mammography screening system was achieved in a short time and with minimal additional resources. One year after introduction of the screening program, most of the quality indicators recommended by the European guidelines had been reached.However, it will be necessary to introduce double reading, to change the rule for BI-RADS 3, and to concentrate on actions toward improving the participation rate.

Laparoscopic radical prostatectomy: transfer validity.

OBJECTIVES: The impact of a formal fellowship training program on the independent practice of the trainees (i.e. transfer validity) has not been evaluated. We analyzed the transfer validity of a structured curriculum in an in-door as well as an out-door setting. METHODS: After completing their training, two fourth generation laparoscopic surgeons who started at the same time compared operative parameters and oncological outcomes in their independent practice, prospectively analyzing the next 100 patients in each. One surgeon continued laparoscopic radical prostatectomy (LRP) in the same center of excellence (Group-In), whereas the other implemented the procedure in a separate academic center (Group-Out). RESULTS: The demographics for both groups (Group-In vs Group-Out) were similar regarding age, prostate volume and preoperative prostate-specific antigen levels. Mean operation times (214.8 vs 224.2 min; P = 0.494) and estimated blood loss (472.4 vs 402.6 mL; P = 0.109) did not differ significantly in both groups as well as complication rate (20 vs 24%), median catheter time (8 vs 8.5 days) and continence rates at 12 months (95 vs 95.5%). According to the pathological stages, the rates of positive surgical margins were similar for pT2 (3.2 vs 4.3%) and pT3 (42.8 vs 45.2%), respectively. CONCLUSIONS: With a well designed, long-term preclinical and clinical fellowship training program, LRP techniques can be efficiently transferred from the center of excellence to other centers with no significant impact on surgical, functional and oncological outcomes.

Breast cancer incidence and mortality in Tyrol/Austria after fifteen years of opportunistic mammography screening.

BACKGROUND: The aim of this study was to analyse breast cancer incidence and mortality in Tyrol from 1970 to 2006, namely after performing more than a decade of opportunistic mammography screening and just before piloting an organised screening programme. Our investigation was conducted on a population level. METHODS: To study time trends in breast cancer incidence and mortality, we applied the age-period-cohort model by Poisson regression to the official mortality data covering more than three decades from 1970 to 2006 and to the incidence data ranging from 1988 to 2006. In addition, for incidence data we analysed data on breast cancer staging and compared these with EU guidelines. RESULTS: For the analysis of time trend in breast cancer mortality in age groups 40-79, an age-period-cohort model fits well and shows for years 2002-2006 a statistically significant reduction of 26% (95% CI 13%-36%) in breast cancer mortality as compared to 1992-1996. We see only slight non-significant increases in breast cancer incidence. For the past five years, incidence data show a 10% proportion of in situ cases, and of 50% for cases in stages II+. CONCLUSIONS: The opportunistic breast cancer screening programme in Tyrol has only in part exploited the mortality reduction known for organised screening programmes. There seems to be potential for further improvement, and we recommend that an organised screening programme and a detailed screening database be introduced to collect all information needed to analyse the quality indicators suggested by the EU guidelines.

Analysis of three different vesicourethral anastomotic techniques in laparoscopic radical prostatectomy.

OBJECTIVES: The vesicourethral anastomosis is critical to the outcome of laparoscopic radical prostatectomy (LRP). We retrospectively compared a recently introduced running suture with existing interrupted techniques. MATERIALS AND METHODS: A total of 600 patients undergoing LRP at our institution were reviewed. Each group consisted of 200 patients. Group 1 (intracorporeal-single-knot-running suture) was compared to cohorts in whom the anastomosis was created by interrupted suturing, with (group 2) or without (group 3) a previously placed 6 o'clock suture. Intraoperative data and cystographic evaluation were collected prospectively. Detailed analysis of the location of extravasation was correlated with duration of leak. At a median follow up of 26 months, continence and stricture rates were assessed. RESULTS: The groups were statistically similar with respect to age, prostate volumes and pre-operative PSA. Numbers of patients undergoing lymphadenectomy and/or nerve-sparing procedures were also similar between groups. The median time for anastomosis was significantly shorter for group 1 (15.3 min) compared to group 2 (23.5 min) and group 3 (27.7 min) (P < 0.000.1). This was reflected in the overall operative times [group 1; 155.4 min, group 2; 185.6 min and group 3; 202.2 min (P = 0.03)]. Subjective assessment suggested that tension to the anastamosis was present in fewer patients in group 1 (3.5%) compared to group 2 (17%) and group 3 (9.5%) (P = 0.001). There was no significant difference in the continence or stricture rate between the three groups. CONCLUSIONS: The continuous anastomotic suture reduced the operative time and tension to the anastomosis. However, the long term continence and stricture rates were unaffected by anastomotic technique.

Complications of laparoscopic pyeloplasty.

OBJECTIVES: With the development of new video-endoscopic techniques like endopyelotomy, laparoscopy and retroperitoneoscopy the treatment of UPJO has become less invasive. The complications and learning curve of laparoscopic pyeloplasty are presented together with recommendations for adequate management. MATERIALS AND METHODS: Based on the personal experience with 189 cases of retroperitoneoscopic pyeloplasty, a literature review (PubMed) was performed focussing on complication and success rates of the procedure. Intraoperative incidents were analysed using the Satava-classification, postoperative complications according to the Clavien-classification. The meta-analysis focussed on the experience of the 3 largest and 2 smaller series representing a cohort of 601 patients. RESULTS: Intraoperative incidents ranged from 2.0 to 2.3% in large series, mostly without consequences for the patient including ligation of lower pole artery, loss of needle, hyperkapnia, cutting of DJ-stent, colonic injury, and port site bleeding. The conversion rate was mainly due to inability to access UPJ or to accomplish the anastomosis ranging between 0.5 and 5.5%. Postoperative complications occured between 12.9 and 15.8% in large series. A total of 5.4-10% represented Grade III-complications, such as urine leakage, haematoma, colonic lesion, and stone formation. Recurrent UPJ-stenosis requiring reintervention was seen in 3.5-4.8%. In all three large series, complications were part of the learning curve. CONCLUSION: Laparoscopic pyeloplasty has been proven safe and effective with comparable results to open surgery. The experience of pioneering centres with incidence and management of complications will be used by next generations of laparoscopic urologic surgeons to shorten their learning curve.

Mechanical simulators for training for laparoscopic surgery in urology.

BACKGROUND AND PURPOSE: The introduction of laparoscopic surgery into urology has led to new training concepts differing significantly from previous concepts of training for open surgery. This paper focuses on the type and importance of mechanical simulators in laparoscopic training. MATERIALS AND METHODS: On the basis of our own studies and experience with the development of various concepts of laparoscopic training, including different modules (i.e., Pelvi-trainer, animal models, clinical mentoring) since 1991, we reviewed the current literature concerning all types of simulators. We focused on training for laparoscopic ablative and reconstructive surgery using mechanical simulators. RESULTS: The principle of a mechanical simulator (i.e., a box with the possibility of trocar insertion) has not changed during the last decade. However, the types of Pelvi-trainers and the models used inside have been improved significantly. According to the task of the simulator, various sophisticated models have been developed, including standardized phantoms, animal organs, and even perfused segments of porcine organs. For laparoscopic suturing, various step-by-step training concepts have been presented. These can be used for determination of the ability of a physician with an interest in laparoscopic surgery, but also to classify the training status of a laparosopic surgeon. CONCLUSIONS: Training in laparoscopic surgery has become an important topic, not only in learning a procedure, but also in maintaining skills and preparing for the management of complications. For these purposes, mechanical simulators will definitely play an important role in the future.

Minimally invasive treatment of ureteropelvic junction obstruction: long-term experience with an algorithm for laser endopyelotomy and laparoscopic retroperitoneal pyeloplasty.

PURPOSE: First line treatment of ureteropelvic junction obstruction is still open dismembered pyeloplasty. The development of videoendoscopic techniques like endopyelotomy and laparoscopy offers less invasive alternatives. The long-term outcome of an algorithm selectively using these techniques is presented. MATERIALS AND METHODS: From February 1995 to March 2006, 256 patients with ureteropelvic junction obstruction were treated with 113 laser endopyelotomies and 143 laparoscopic retroperitoneal pyeloplasties. According to changing selection criteria, an early group (92 in 1995 to 1999) treated with laser endopyelotomy for extrinsic as well as intrinsic stenoses, and a late group (164 in 2000 to 2006) treated with laser endopyelotomy for intrinsic stenosis, were evaluated. In the late group extrinsic ureteropelvic junction obstruction was treated with nondismembered pyeloplasty in cases of anteriorly and by dismembered pyeloplasty in cases of posteriorly crossing vessels or a redundant renal pelvis. RESULTS: Operating time of laser endopyelotomy averaged 34 (range 10 to 90) minutes with a complication rate of 5.3% and a success rate of 72.6% (intrinsic 85.7% vs extrinsic 51.4%). Operating time of laparoscopic retroperitoneal pyeloplasty averaged 124 (range 37 to 368) minutes with a 6.3% complication rate and an overall success rate of 94.4% (intrinsic 100% vs extrinsic 93.8%). In the late group the LAP success rate was 98.3% with no significant differences related to the cause of ureteropelvic junction obstruction (intrinsic 100% vs extrinsic 98.1%) or the type of pyeloplasty (YV plasty 97.0% vs Anderson-Hynes 97.7%). CONCLUSIONS: Laparoscopic retroperitoneal pyeloplasty yields an efficacy similar to that of open surgery. The inferior success of laser endopyelotomy even in optimally selected cases and the increasing expertise with endoscopic suturing may favor laparoscopic pyeloplasty with or without robotic assistance in the future.

Ultrasound-guided core needle biopsy of the breast: does frozen section give an accurate diagnosis?

Reducing the period of uncertainty between the discovery of a breast tumor and histological diagnosis alleviates the psychological impact of breast cancer to an important degree. We aimed to verify whether histological results obtained with frozen sections of core needle biopsies (CNBs) offer an accurate and reliable tool for minimising this period. In 2619 cases we compared histological diagnosis on frozen sections with those on paraffin sections of CNB and finally with the results of open biopsies. Of the cases 49% were proved malignant and 51% benign. In 99.3% of the malignant lesions preceding CNB was correctly classified as B5 (n = 1185, 92.9%) or at least B4 (n = 82, 6.4%) in frozen and in paraffin sections. There were seven false-negative cases in frozen (false-negative rate = 0.5%) and five false-negative cases (false-negative rate = 0.4%) in paraffin sections of CNB. On frozen sections complete sensitivity was 99.5% and the positive predictive value of B5 was 99.9%. There was one false-positive case in frozen sections and one in paraffin sections. False-positive rate = 0.08%, negative predictive value for B2 = 99.4% for frozen and 99.6% for paraffin sections; full specificity was 85.9 for frozen and 85.8 for paraffin sections of CNBs. Immediate investigation of CNB in frozen sections is an accurate diagnostic method and an important step in reducing psychological strain on patients with breast tumors and may be offered by specialised Breast Assessment Units.

The radius surgical system - a new device for complex minimally invasive procedures in urology?

OBJECTIVE: Complex laparoscopic procedures in urology are technically demanding with an extended learning curve. Robotic systems add significant cost to laparoscopic procedures. We therefore evaluated the use of the Radius Surgical System (RSS), a mechanical manipulator, for complex laparoscopic cases in urology. MATERIAL AND METHODS: The RSS (Tuebingen Scientific) consists of two hand-guided surgical manipulators and provides a deflectable and rotatable tip allowing six degrees of freedom. We evaluated the system by using a series of standardized models in the pelvitrainer. We analyzed the effectiveness of the system and the learning curve. We then evaluated the system in the clinical setting during laparoscopic radical prostatectomy. RESULTS: Surgeons with experience on the RSS were compared to surgeons without previous experience on the system. We identified a learning curve in those participants without experience on the system only when performing complete anastomoses in the pelvitrainer. However, this learning curve included less than 10 anastomoses. The first clinical experiences during laparoscopic extraperitoneal radical prostatectomy (n=10) are promising. All anastomoses were patent on routine (X-ray) examination 8 days after surgery. CONCLUSIONS: The RSS system is easy to use and we identified a very short learning curve. We now optimize the system for use in urology. This device may facilitate complex laparoscopic procedures without the use of costly robotic systems and should be further evaluated in the experimental and clinical setting.

Assessing the predictive validity and efficacy of a multimodal training programme for laparoscopic radical prostatectomy (LRP).

OBJECTIVES: To assess the predictive validity (ability to correlate to real-life environment) and efficacy of a training programme for laparoscopic radical prostatectomy (LRP), based on a structured and progressive pelvitrainer component with hands-on clinical training in the operating room (OR). METHODS: Prospective data on 500 LRP cases were analysed with 80 excluded due to incomplete records. The operation was divided into multiple steps. Times for these steps were compared among 11 surgeons with different laparoscopic expertise (first-, second-, and third-generation surgeons in order of decreasing experience) and correlated to times for specific exercises on the pelvitrainer that simulated particular steps. Perioperative parameters were also evaluated among the three groups. RESULTS: Pelvitrainer times achieved by trainees (third-generation surgeons) did not differ significantly with times for corresponding steps of LRP. There was also no significant difference for total OR time between the second- and third-generation surgeons (205 and 207 min, respectively; p>0.05) although the time for the first-generation surgeons was faster than both (176 min). Short-term quality indicators for first, second, and third generations included transfusion rates (2.3%, 2.4%, and 2.6%, respectively), positive margin rates (20.3%, 21.5%, and 23.0%) and complications, which did not differ significantly among the generations although the first-generation surgeons had the lowest rates. CONCLUSIONS: A carefully designed training programme that incorporates both pelvitrainer and mentor-based operative training is essential for the effective and safe transfer of skills and knowledge required to learn LRP.

Anatomic nerve-sparing laparoscopic radical prostatectomy: comparison of retrograde and antegrade techniques.

OBJECTIVES: To compare the anatomic retrograde and antegrade preservation of the neurovascular bundle (NVB) during laparoscopic radical prostatectomy. METHODS: Anatomic studies were reviewed, focusing on the fascial layers surrounding the prostate and NVB and the terminology used as described by Walsh and colleagues. Important operative steps have been illustrated using video clips. For the retrograde technique, after incision of levator fascia, the NVBs were released from the apex before division of the urethra. Along the plane between the laterally incised Denonvilliers and perirectal fascia, the prostate was mobilized from the rectum. Isolated clipping of the seminal vesicle arteries was performed in an antegrade manner, followed by control of the lateral pedicles, and identification of the course of the NVB. For the antegrade technique, after dissection of the seminal vesicles, the levator fascia was incised to develop a lateral NVB groove. After bladder neck division and lateral pedicle ligation, the lateral NVB groove was used as a guide for antegrade preservation of the NVB. During anastomosis, the NVBs located at the 5-o'clock and 7-o'clock positions were avoided in both techniques. RESULTS: A questionnaire-based potency rate of 67% and 76%, respectively, was reported after bilateral nerve sparing using retrograde and antegrade laparoscopic radical prostatectomy techniques. CONCLUSIONS: Both techniques allowed replication of open surgical principles. The video magnification enabled excellent demonstration of the periprostatic anatomy. The principles of interfascial dissection of the NVB, use of task-specific instrumentation, and avoiding energy sources around the NVB may be more important than the actual nerve-preservation technique used.

The impact of neoadjuvant hormonal therapy on the outcome of laparoscopic radical prostatectomy: a matched pair analysis.

PURPOSE: We evaluated the effect of androgen ablation treatment on laparoscopic radical prostatectomy operative and postoperative parameters. MATERIALS AND METHODS: A total of 50 patients (group 1) on neoadjuvant androgen deprivation, followed by laparoscopic radical prostatectomy, were compared to 50 (group 2) without any treatment who were matched for prostate volume, laparoscopic pelvic lymphadenectomy, nerve sparing procedure, surgical access type and pathological stage. We analyzed operative time, blood loss, intraoperative and postoperative complications, catheter time, procedure difficulty as scored by the surgeon and surgical margin status. RESULTS: There was no significant difference between the neoadjuvant and nonneoadjuvant groups with respect to mean operative time +/- SD (228.6 +/- 62.9 vs 219.4 +/- 65.1 minutes), mean blood loss (667.6.1 +/- 217.1 vs 729.8 +/- 285.1 ml) and median catheter time (7 vs 7.5 days). We also found no difference related to the complication rate. Ten of 50 prostate dissections (20%) in group 1 were classified as difficult, whereas in group 2 only 4 of 50 (8%) were scored as difficult (p = 0.084). The positive surgical margin rates did not differ. CONCLUSIONS: There was no significant difference with respect to operative or postoperative parameters in patients undergoing neoadjuvant androgen ablation therapy compared to controls. At centers where there is experience laparoscopic radical prostatectomy can be safely performed in patients who have undergone neoadjuvant hormonal therapy.

Multislice computed tomography for detection of patients with aortic valve stenosis and quantification of severity.

OBJECTIVES: The purpose of this study was to evaluate whether multislice computed tomography (MSCT) provides a reliable, noninvasive imaging modality for identification of patients with degenerative aortic valve stenosis (AS) by quantifying the aortic valve area (AVA) in comparison to the accepted diagnostic standard transthoracic echocardiography (TTE). BACKGROUND: Management of patients with degenerative AS is based on the severity of disease. The severity of AS in clinical practice is assessed by TTE and classified as mild, moderate, or severe according to the AVA. METHODS: Forty-six patients were examined with contrast-enhanced, electrocardiogram-gated, 16-row MSCT for the evaluation of the diagnostic accuracy. In 30 patients, quantification of the AVA with MSCT was compared to TTE using the continuity equation with Doppler velocity-time integral for calculation of the AVA. RESULTS: Sensitivity of MSCT for the identification of patients with degenerative AS was 100%, and the specificity was 93.7%. Thirty of 46 patients had AS determined by TTE. Quantification of AVA by MSCT (mean AVA = 0.94 cm2) in patients with AS showed a good correlation to TTE (r = 0.89; p < 0.001). Bland-Altman plot illustrated good intermodality agreement between the two methods (limits of agreement, 0.20; 0.29). CONCLUSIONS: Multislice computed tomography may provide an accurate, noninvasive imaging technique for detection of patients with AS and quantification of AVA.

Comparison of training modalities for performing laparoscopic radical prostatectomy: experience with 1,000 patients.

PURPOSE: We report a detailed analysis of different training modalities on the transferability of laparoscopic radical prostatectomy to generations of surgeons. MATERIAL AND METHODS: The first generation surgeon with experience with 600 cases and the second generation surgeon with 150 were trained in open retropubic radical prostatectomy and laparoscopy, whereas the third generation surgeon with 150 cases was trained only laparoscopically. The fourth generation of surgeons with a total of 50 cases was trained in our fellowship program. We analyzed groups of 50 operations. The groups were comparable with respect to patient age, prostate weight and pathological tumor stage. RESULTS: We observed a continual decrease in operative time between (322 to 247 minutes.) and within (332 to 196 minutes.) the analyzed groups. This result was also expressed in a decrease in the time required for anastomosis. A significant decrease was observed for the initial transfusion rate (4% to 10%). No difference was found in the complication rate (ie conversion in 8% to 0% of cases). Pathological outcomes (ie positive margins for pT2/pT3) were comparable in the first 3 surgeon groups (14.9%, 14.2% and 22%, respectively) and available functional results (followup greater than 2 years) did not reveal any influence of the learning curve. A learning curve was observed only for overall operative time and the time required for anastomosis but it was shown to be significantly shorter for the following generations. CONCLUSIONS: Based on a specific training program the personal level of education has a minor impact on the results and reproducibility of the laparoscopic radical prostatectomy technique.
