OBJECTIVE To evaluate the functional and cancer results of radical prostatectomy with bladder neck preservation in the treatment of localized prostate cancer. MATERIAL AND METHOD From January 2000 to March 2006, 194 consecutive patients underwent open retropubic radical prostatectomy for localized prostate cancer. The bladder neck was technically preserved in 180 patients (93%). The mean age of these 180 patients was 63.2+/-6.1 years. The mean preoperative PSA was 9.38+/-6 ng/ml. The 180 patients were classified according to the Amico prognostic classification as low risk: 52.2%, intermediate risk: 37.8% and high risk: 10%. Operative specimens were examined by the same pathologist according to the Stanford technique. Positive surgical margin was defined as tumour tissue in contact with the ink of the operative specimen. For analysis of the functional results, patients were classified into three categories: continent without protection, stress incontinent, totally incontinent. Continence was evaluated at D10, one month, six months, one, two, three, four and five years. The mean follow-up was 44+/-25 months. RESULTS This series of 180 operative specimens comprised 64 (35.6%) cases of positive surgical margins and 112 (62.2%) pT3 cancers. No positive margins were observed in the bladder neck, either alone or associated with another positive margin. Seventy-one percent of patients were continent on D10 and at one month, 85% were continent at six months and 89% were continent at one year. Two cases of anastomotic stenosis were observed (1.2%). CONCLUSION Bladder neck preservation during open retropubic radical prostatectomy allows early continence in more than 70% of cases without increasing the risk of positive surgical margins.

PURPOSE We evaluated the success of endoscopic treatment of symptomatic vesicoureteral reflux after renal transplantation and identified factors predicting success. MATERIALS AND METHODS Endoscopy was performed for symptomatic vesicoureteral reflux after renal transplantation in 38 women and 20 men between January 2000 and December 2010. Reflux was documented by retrograde cystography and its symptomatic character was determined by at least 1 episode of acute graft pyelonephritis. The results of endoscopic treatment were evaluated clinically at 1 and 3 months, and annually, and by cystography at 3 months. Clinical success was defined as absent acute graft pyelonephritis during followup. Radiological success was defined as absent reflux on followup cystography at 3 months. RESULTS Endoscopic treatment was clinically successful in 32 patients (56.1%), including 26 (65%) who received dextranomer-hyaluronic acid and 5 (33.3%) who received polydimethylsiloxane. Treatment was radiologically successful in 14 patients (26.4%) at a mean ± SD followup of 38 ± 33 months. On multivariate analysis male gender and dextranomer-hyaluronic acid were factors predictive of clinical success. Reflux grade did not predict success or failure. No high grade complication was reported. CONCLUSIONS Endoscopic treatment of symptomatic vesicoureteral reflux of a transplanted kidney was effective in half of the cases regardless of the bulking agent used. However, dextranomer-hyaluronic acid appeared to be more effective than polydimethylsiloxane. Due to its minimally invasive nature and low morbidity endoscopic treatment with dextranomer-hyaluronic acid could be proposed as preoperative first line treatment for symptomatic vesicoureteral reflux of a transplanted kidney regardless of reflux grade.

OBJECTIVE To evaluate our results of retrograde laser endopyelotomy for uretero-pelvic junction obstruction. MATERIAL AND METHODS Retrospective study of 27 consecutive retrograde laser endopyelotomies performed on 24 patients over a six years period (June 1999 to July 2005). Sixteen stenoses were primary. The level of obstruction was severe in 13 patients and moderate in 14 patients. A polar pedicle was diagnosed by pre-operative CT-angiography in seven cases. Balloon dilatation was performed in 17 procedures. A double J ureteral stent remained in place for six weeks mean. We evaluated results by a clinical examination and an excretory urography (at 1 and 6 months then annually). Mean follow-up was 35+/-22.7 months. RESULTS Mean operating time and mean length of hospital stay were 49.8+/-17.9min and four days (range: 2-10 days). Two cases of pyelonephritis were observed. The overall success was 70%. In the eight unresolved cases, the failure appeared at 2.7+/-1 month mean. Success criteria were moderate level of obstruction and primary junction. Here, patients so selected have 100% of success. CONCLUSION Study confirmed retrograde laser endopyelotomy was safety with a short length of hospital stay. This minimally invasive procedure should be reserved to primary moderate stenoses without polar pedicle.

The spironolactone is a diuretic of potassium savings. It is also used in the treatment of the hirsutism for its antiandrogenic action. Its use and its effects on the patients affected by a prostate cancer are less known. We report the case of a 72-year-old man having a cancer of prostate which normalized its PSA after institution of a treatment by spironolactone for ascites. This patient had a biological recurrence of a prostate cancer, arisen 7 years later after a treatment by hormonal radiotherapy. Nine months after the implementation of the treatment by spironolactone, there were no clinical and biological signs of disease progress.

OBJECTIVES To evaluate the results of partial nephrectomy (NP) for cancer in 60 patients selected by the biopsy of the tumor by analyzing the information, oncologic follow-up. PATIENTS It was a cohort study unicenter retrospective from 1994 to 2006. The biopsy was systematically done for patients who were candidates for elective NP. The criteria for elective indications NP tumors were less than 4cm, low grade Fuhrman (I and II). The tubulopapillary tumors (TBP) on biopsy were excluded from the elective indications. The parameters studied were the biopsy data, overall survival, disease-free survival. RESULTS The median age was 59 years (32-79 years) and 69% of tumor were fortuitous discovery. Indications of need accounted for 30% of cases (single kidney, bilateral tumors and chronic renal failure [CRF]). Biopsy allowed a diagnosis in 89% of cases. There was one death in specific postoperative immediately. A final histology was 75% of clear cell carcinoma, 13.3% of chromophobe and 11.7% of TBP, 96.6% of T1a including 86.6% of low grade and no surgical margin. The median follow-up was 49 months with 98.5% of specific survival at 5 years, one local recurrence and no general recurrence. CONCLUSION The study has shown that the selection of patients by biopsy gives satisfactory carcinologic results with 98.5% specific survival at the end of follow-up; it is between 89 and 100% in the literature.
