Introduction: After the first feasibility report in 1997, a growing interest has risen in the urologic community for laparoscopic radical prostatectomy (LRP) and several authors have contributed to the evolution of the technique. We attempt a review of the available evidences and provide a broad framework of different technical refinements considering their impact on pentafecta., Evidence Acquisition: The PubMed/Medline database was searched. Duplicates and "Expert opinion" papers were removed. Studies were included according to the aim of the present paper to present a selected review on LRP and report our personal experience., Evidence Synthesis: In 1999 Guillonneau et al. codified their transperitoneal-posterior-antegrade technique for LRP. Since then, several modifications of the transperitoneal approach were published and the extraperitoneal route was also proposed. Sparing the bladder neck and reconstructing the posterior muscolofascial plate were proven to improve continence rate. Nerve-sparing LRP were performed in order to maximize postoperative recovery of the sexual function. Novel techniques to ligate the Santorini plexus and sew the urethrovesical anastomosis provided improvement in operative time, intraoperative blood loss and reduced the incidence of postoperative urinary-leakages. In the recent years, the single-site approach as pushed the limits of LRP and three-dimensional (3D) systems for endoscopic surgery were developed., Conclusions: Thanks to several technical improvements, LRP provides brilliant oncologic and functional outcomes and it is now considered the treatment of choice in many institutions worldwide. Although it is a technically demanding procedure, the recent introduction of 3D systems will reduce the steepness of its learning curve.

Purpose: To evaluate peri- and postoperative morbidity, and long-term oncologic and functional results of our laparoscopic radical cystectomy (LRC) technique, comparing it with our standard open approach., Methods: Between 2000 and 2010, 54 patients underwent LRC for urothelial cell carcinoma of the bladder in two academic hospitals. The procedures were performed by two surgeons. Patients were matched 1:1 with patients who underwent open RC in the same years by the same surgical team. Differences in peri- and postoperative complications across the two groups were assessed using Wilcoxon's rank-sum or χ (2) test. Kaplan-Meier curves, log-rank tests and Cox regression models were constructed to assess differences in recurrence-free survival on long-term follow-up between the two groups., Results: Laparoscopic radical cystectomy was significantly associated with lower blood loss (p < 0.0001) and less frequent postoperative ileus (p = 0.03). Regarding more serious postoperative complications, no difference was found across the two cohorts. Median oncologic follow-up was 42 months (IQR 12-72 months) in the LRC cohort and 18 months (IQR 8-27 months) in patients undergoing open radical cystectomy (ORC). No statistically significant difference in recurrence-free survival was observed between the two groups (log rank p = 0.677). On univariate Cox regression, the surgical approach used was not significantly associated with risk of recurrence., Conclusions: We found that LRC is safe and associated with lower blood loss and decreased postoperative ileus compared with ORC. Moreover, on long-term oncologic follow-up, LRC appeared non-inferior to ORC with no significant difference in recurrence-free survival. Nonetheless, these results must be confirmed by larger series and stronger long-term follow-up data are needed.

Background: Magnetic resonance imaging (MRI) and MR spectroscopic imaging (MRSI) have been gaining acceptance as tools in the evaluation of prostate cancer. We compared the accuracy of transrectal ultrasound (TRUS)-guided biopsy and dynamic contrast-enhanced MRI combined with three-dimensional (3D) MRSI in locating prostate tumours and determined the influence of prostate weight on MRI accuracy., Patients and Methods: Between March 1999 and October 2006, 507 patients with localised prostate cancer underwent radical prostatectomy (RP) at the Jules Bordet Institute. Of these, 220 had undergone endorectal MRI (1.5 T Siemens Quantum Symphony) and 3D-MRSI prior to RP. We retrospectively reviewed data on tumour location and compared the results obtained by MRI and by TRUS-guided biopsy with those obtained on histopathology of the RP specimen., Results: Patient data were as follows: median age 62.4 years (45-74); median PSA 6.36 ng/ml (0.5-22.6); 73.6% of patients had non-palpable disease (T1c); median biopsy Gleason score 6 (3-9); median RP specimen weight 50 g (12-172); median pathological Gleason score 7 (4-10); 68.64% of patients had organ-confined (pT2) disease. Tumour localisation was correlated with RP data in a significantly higher percentage of patients when using MRI rather than TRUS-guided biopsy (47.4 vs. 36.6%, p < 0.0001). MRI was marginally superior to TRUS-guided biopsy in detecting malignancy at the prostate apex (48.3 vs. 41.9%, p = 0.0687) and somewhat better at the prostate base (46 vs. 39.1%, p = 0.0413). It was highly significantly better at mid-gland (52 vs. 41.1%, p = 0.0015) and in the transition zone (40.1 vs. 24.3%, p < 0.0001). MRI had higher sensitivity in larger (≥50 g) than smaller (<50 g) prostates (50.3 vs. 42.2%, p = 0.0017)., Conclusions: MRI was superior to TRUS-guided biopsy in locating prostate tumours except at the gland apex. MRI was more accurate in larger (≥50 g) than smaller prostates., (Copyright © 2011 S. Karger AG, Basel.)

Advanced atherosclerosis or thrombosis of iliac vessels can constitute an absolute contraindication for heterotopic kidney transplantation. We report the case of a 42-year-old women with end-stage renal disease due to lupus nephritis and a history of bilateral thrombosis of iliac arteries caused by antiphospholipid antibodies. Occlusion had been treated by the bilateral placement of wall stents which precluded vascular anastomosis. The patient was transplanted with a right kidney procured by laparoscopic nephrectomy from her HLA semi-identical sister. The recipient had left nephrectomy after laparoscopical transperitoneal dissection. The donor kidney was orthotopically transplanted with end-to-end anastomosis of graft vessels to native renal vessels and of the graft and native ureter. Although, the patient received full anticoagulation because of a cardiac valve and antiphospholipid antibodies, she had no postoperative complication in spite of a short period of delayed graft function. Serum creatinine levels three months after transplantation were at 1.0 mg/dl. Our case documents that orthotopical transplantation of laparoscopically procured living donor kidneys at the site of recipient nephrectomy is a feasible procedure in patients with surgical contraindication of standard heterotopic kidney transplantation.

Since 1965, more than 2000 renal transplantations (including more than 100 living-donor transplantations) have been performed at the University of Brussels. An end-stage renal disease patient candidate to renal transplantation will be therefore followed from his enrolment on the waiting list to the long-term post-transplant period. Improvement in the outcome of renal transplantation is achieved due to better knowledge in many fields of medicine, such as immunology, infectious disease, metabolic diseases (hyperlipemia, diabetes mellitus), pharmacology, use of immunosuppressive regimen, a more adequate cardiovascular prevention and treatment. If the best results were achieved with kidneys from living donors, the graft survival rate at the University of Brussels was nearly 80% for the last period (2000-2006). Unfortunately, renal transplantation cannot cure certain comorbid conditions and even may promote them: infectious diseases, neoplasia, metabolic disorders (e.a diabetes mellitus, hyperlipemia). Many efforts have to be done to develop less toxic and more immune selective therapeutic strategies. Living donation and extension of the pool of cadaveric donors will reduce the length of time spent on the waiting list and will significantly impact on mortality and morbidity after kidney transplantation.

Objectives: To investigate the impact of "on-demand" clamping during laparoscopic partial nephrectomy on warm ischemia time., Methods: We retrospectively reviewed 39 consecutive patients with renal tumors who had undergone transperitoneal laparoscopic partial nephrectomy from April 2002 to May 2006. Median tumor size was 2.3 cm. In all cases, the hilum was dissected early and extracorporeal clamping performed. The pedicle was clamped only in case of excessive bleeding, and it was released immediately after the closure of the renal defect with knot-tying sutures over Surgicel bolsters., Results: Median operative time was 120 min. Renal clamping was required in 31 of 39 patients and in this subgroup the median warm ischemia time was 9 min. Median operative blood loss was 150 ml. Eight patients required blood transfusion and among these two were converted to open surgery. Positive surgical margin was observed in one case. Renal cell carcinoma was present in 22 (54.4%) specimens. No recurrence was observed after a median follow-up of 15 mo., Conclusions: This novel technique using extracorporeal clamping significantly decreases warm ischemia time, avoiding clamping of the pedicle in selected cases. Our study underlines the feasibility of performing laparoscopic partial nephrectomy with extracorporeal hilar clamping, allowing the shortest ischemia time ever published., (European Association of Urology.)

Objectives: To evaluate the technical and oncologic feasibility of laparoscopic nephroureterectomy for upper urinary tract transitional cell carcinoma., Methods: A retrospective survey of 100 patients, treated with laparoscopic nephroureterectomy in 10 Belgian centres, was performed. Most procedures were performed transperitoneally. The distal ureter was managed by open surgery in 55 patients and laparoscopically in 45 patients. The mean follow-up was 20 mo., Results: Mean operation time was 192 min and mean blood loss 234 ml. The conversion rate was 7%. Important postoperative complications were seen in 9%. Pathologic staging was pTa in 31 patients, pT1 in 23, pT2 in 12, pT3 in 33, and pT4 in 1, concomittant pTis in 3. Pathologic grade was G1 in 24 patients, G2 in 28, and G3 in 48. Negative surgical margins were obtained in all but one patient. Twenty-five patients developed progressive disease (24%) at a mean postoperative time of 9 mo (local recurrence in 8%, metastases in 11%, both in 5%). Progression was 0% for pTa, 17% for pT1, 17% for pT2, 51% for pT3, and 100% for pT4. Cancer-specific survival was 100% for pTa, 86% for pT1, 100% for pT2, 77% for pT3, and 0% for pT4., Conclusion: Laparoscopic nephroureterectomy appears to be a technically and oncologically feasible operation. To prevent tumour seeding, one should avoid opening the urinary tract and should extract the specimen with an intact organ bag. The high local recurrence rate in this study probably reflects the high percentage of high-grade and high-stage tumours in this study.

Objectives: To report the utilization of a modified Endo GIA vascular stapler to obtain the full length of the renal vein during transperitoneal laparoscopic live donor right nephrectomy., Methods: We used a modified Endo GIA stapler, in which the triple staggered rows of staples were removed from the kidney donor side to obtain the full length of the right renal vein. This technique has currently been used in nine consecutive transperitoneal laparoscopic right donor nephrectomies., Results: With this technique, the entire right renal vein length was harvested in all cases, without vascular complications. Mean renal warm ischemia time from clamping of the renal vessels to cold perfusion was 135s, and mean receptor postoperative glomerular filtration rate after 30 d was 67.3 ml/min. There were no graft losses., Conclusions: A novel technique for laparoscopic live donor right nephrectomy is described. It allows harvesting the full length of the right renal vein in a safe and feasible way without compromising warm ischemia time.

Purpose of Review: Laparoscopic radical prostatectomy is now an accepted treatment option for the management of localized prostate cancer. Numerous studies have demonstrated the feasibility and the reproducibility of this procedure. Expert teams in high-volume centres routinely carry out laparoscopic radical prostatectomy but for the novice the obstacle to success is how to learn and gain proficiency in this procedure. In this review, we will present our views on how this can be done., Recent Findings: A learning curve includes the necessity for continuous self-evaluation in terms of cancer control, continence and potency. Many different methods can be used to acquire the technique: dry lab, animal live lab, cadaveric laparoscopic dissection or mentoring with an expert. All of these steps may not be essential as laparoscopic radical prostatectomy is not too dissimilar to open prostatectomy. However, one must understand that the physiological consequences of anaesthesia during laparoscopy and basic laparoscopic suturing technique should be perfected prior to taking on laparoscopic radical prostatectomy. The training then must continue under the supervision of a mentor. The opportunity for discussion with an expert allows the novice to learn the pitfalls and the tips and tricks of laparoscopic radical prostatectomy, thus reducing the length of the learning curve and negating the need to reinvent the wheel., Summary: Laparoscopic radical prostatectomy is similar to any other new surgical procedure and as with open surgery we learn and gain experience with each procedure; the learning curve is never completely finished.

Since the past 10 years, results have established laparoscopy's efficacy. It is actually a consistent surgical option for a lot of indications met in urology. The rational behind performing laparoscopic procedures includes shorter hospital stays, less postoperative pain and a more rapid return to usual activity. Drawbacks of laparoscopy include significant learning curve, longer operative times and higher overall costs. One particular focus is the oncologic applications of laparoscopy for nephrectomy and specially for radical prostatectomy. Laparoscopy become nowadays an usual part of the armamenturium of urological teams.

We prospectively compared, within the same center and during the same period of time, the perioperative parameters as well as the oncological and functional results of both open retropubic (ORP) and laparoscopic radical prostatectomy (LRP). From September 1999 to September 2001, 162 patients with prostate cancer were treated with radical prostatectomy, 77 using an open retropubic technique, and 85 by the laparoscopic extraperitoneal approach. We prospectively recorded pre-, per- and postoperative parameters and complications, and evaluated the carcinological and functional results, comparing both approaches. There were no significant differences in the preoperative characteristics of the two groups. Mean operative time was statistically longer with LRP than with ORP (288 vs 168 min, P<0.0001) but median blood loss was decreased (400 vs 1,300 ml, P<0.0001). Major complications occurred in a similar number of cases (5% vs 2.4%, NS) while minor complications occurred more frequently with ORP (24.6 vs 11.8%, P=0.003). Pathological examination revealed a similar distribution of Gleason scores and stages in each group. Positive surgical margins in pT2 cases occurred in 7.8% of LRP and 7.3% of ORP. Continence rates (no pad and no leakage at all) were similar (83.9% in ORP vs 80.7% in LRP, NS). Potency rates were similar after 1 year in patients undergoing bilateral nerve sparing (55% in ORP vs 65% in LRP, NS). However, patients operated by LRP had more spontaneous erections. We conclude that this prospective, comparative study shows that LRP, when performed in specialized centers, gives oncological and functional results comparable to open surgery.

Over the past years, laparoscopic radical prostatectomy has emerged as an attractive, exciting, and new approach for the surgical treatment of localized prostate cancer. Several centers in Europe and the United States have developed their own technique and have already published their first results. Two main routes have been used, namely, the transperitoneal and extraperitoneal approaches. Data from the literature and available experience demonstrate that this laparoscopic procedure is feasible and teachable and that oncologic and functional results seem comparable to those of classic open radical prostatectomy. Minimal bleeding, reduced blood transfusion rates, shorter hospitalization, and shorter recovery time are unquestionable advantages for laparoscopic procedures. Laparoscopic radical prostatectomy remains a difficult intervention and should be performed in selected centers with experienced teams who already have extensive laparoscopic experience and who recruit enough patients to grant them the proper amount of expertise. This is the only way to achieve excellence in terms of oncologic and functional results.

The Department of Urology of Erasme Hspital, University of Brussels, has participated to the development and implementation of new technologies that have significantly transformed the specialty in the last 25 years. The minimally invasive treatment of benign prostatic hypertrophia was developed by the use of Trans-Urethral Needle Ablation (TUNA) and new pharmacological treatments. Treatment of urinary stones by extracorporeal shockwaves lithotripsy and Endourology has allowed to avoid operating hundred of patients each year. In the field of prostate cancer, an original laparoscopic prostatectomy technique by the extraperitoneal approach was developed in our unit. The prevention of prostate cancer and the influence of various nutritional factors and its early diagnosis by the use of different markers have been the subject of numerous publications and have contributed to improve our knowledge in this field. Different prognostic factors of bladder cancer have been evaluated and in particular their place with the use of intravesical BCG. A better understanding of the different mechanisms involved in erectile dysfunction has been the subject of numerous studies during the last 20 years and the department is internationally recognised as a reference centre in this field.
