- Abstract
Introduction: Spinal cord compression (SCC) in metastatic prostate cancer is not rare occurring in 1 to 12% of patients. We have analysed patients treated for this condition in our institution assessing outcome and prognostic factors., Material and Methods: Retrospective analysis of the notes of 24 patients hospitalised with SCC due to metastatic prostate cancer from 1987 to 2001., Results: At presentation 3 patients were ambulant with mild neurological deficit, 12 patients were paraparetic and 9 patients were paraplegic. Diagnosis was established by emergency myelogram, CT-scan or MRI of the spine. 8 patients had received no hormone treatment prior to diagnosis of SCC. 19 patients presented dorsal or lumbar pain requiring opioid treatment on average 60 days before onset of neurological symptoms (range 10-840). All patients underwent steroid treatment; the 8 patients without prior hormone therapy were treated with bilateral orchidectomy, 1 out of these 8 patients had castration without other treatments; 12 patients underwent radiotherapy alone and 9 radiotherapy and laminectomy; 2 patients were in terminal conditions and receive only steroid treatment. Overall 15/24 patients were ambulant after treatment. 8 out of 9 patients treated by laminectomy and radiotherapy were ambulant after treatment versus 7 out of 12 patients treated by radiotherapy alone.17 patients died during follow-up with a median survival of 4 months (2 weeks to 49 months). 7 patients were alive at the last control with a mean follow-up of 10 months (range 4-40)., Conclusion: Outlook in patients with spinal cord compression from metastatic prostate cancer is poor. Efforts must be concentrated on prevention of spinal cord compression. Patients with hormone resistant prostate cancer who develop persistent back pain should undergo imaging studies (bone scan, spine CT-scan or MNR) and prophylactic local radiotherapy to the spine if bony metastases are identified.

- Abstract
Objectives: The aim of the study was to determine whether a nonoperative approach is able to reduce renal parenchymal loss after renal trauma., Methods: Sixty-four consecutive patients with major blunt renal lacerations were treated from 1988 to 1999. Initial management was conservative. In group 1 (35 patients) delayed hemorrhage, persistent urinoma or hemodynamic instability were dealt with by open surgery. In group 2 (29 patients), most complications were dealt with using endoscopic procedures; open surgery was reserved exclusively for major complications., Results: In group 1, 7 patients were not operated and 28 patients were managed surgically. Twenty (57%) patients underwent total (8) or partial (12) nephrectomy. In 8 patients the surgical intervention was open drainage of perinephric collection (6) and/or renorrhaphies (2). Four patients in this group developed urinary fistulae treated successfully with ureteral stents. Length of hospital stay was 9.6 days (3-25 days). In group 2, persistent hemodynamic instability led to nephrectomy in 1 case. The remaining 28 patients were managed conservatively, with endoscopic ureteric stenting in 5 cases. A persistent urinary extravasation with hyperthermia led to open drainage of perinephric urinoma (5) and renorrhaphy (2). No delayed nephrectomy was necessary. Average hospital stay was 12 days (5-21 days). Only 1 patient in this group developed hypertension., Conclusion: For most patients and with close follow-up available, conservative treatment represents a real alternative to open surgery in major blunt renal lacerations. In our experience, open surgery usually results in loss of renal parenchyma.

- Abstract
Objectives: To study the influence of adverse reactions on adherence to an immunotherapy maintenance schedule and the recurrence rate of bladder cancer. Bacille Calmette-Guérin immunotherapy has documented efficacy in the management of high-risk superficial bladder cancer. However, the optimal duration of intravesical bacille Calmette-Guérin therapy and the risk/benefit ratio of maintenance therapy are controversial., Methods: From April 1996 to April 2000, 72 patients with superficial bladder cancer were treated with Immucyst (six consecutive weekly instillations of 81 mg) and then received maintenance therapy consisting of three consecutive weekly instillations 3, 6, 12, 18, 24, 30, and 36 months later. Adverse reactions, studied during 518 instillations, were classified in four categories using a scale based on the World Health Organization recommendations, and their impact on the adherence to therapy was analyzed., Results: After an average follow-up of 24 months, a durable disease-free response was observed in 84.9% of the patients; 12.5% of patients had a relapse and 2.6% had disease progression. The response rate was similar in patients with and without adverse reactions. Only 14 patients (19%) received all the scheduled maintenance instillations. The dose was reduced in 41 patients (57%), and treatment was stopped in 28 patients (39%). In multivariate analysis, an adverse event score of 1.5 or greater during induction therapy was significantly associated with cessation or modification of maintenance therapy (P = 0.01)., Conclusions: The scale developed in this study to monitor the adverse reactions to bacille Calmette-Guérin and their impact on the adherence to maintenance therapy may be helpful for tailoring maintenance regimens or implementing protective measures (dose reduction or treatment postponement).

- Abstract
Objectives: To examine leukocyturia as a predictor of tumor recurrence and occurrence of adverse events after bacille Calmette-Guérin (BCG) immunotherapy. The use of BCG immunotherapy, a very major advance in the management of superficial bladder cancer, is limited by the frequency of adverse events. As yet, we have no way of predicting the efficacy and tolerability of BCG instillation in clinical practice. This problem is even more acute during BCG maintenance therapy., Methods: Adverse events in 72 patients who received 518 instillations were prospectively assessed using a four-class scale based on severity and duration. Urinary leukocytes were counted 3 days after each instillation, using the KOVA-Slide 10 method., Results: High leukocyturia during BCG treatment (cutoff value 1.65 x 10(5)/mL urine) correlated with recurrence-free status (P = 0.009). The degree of leukocyturia correlated with the severity/duration of adverse events (P <0.0001); the median leukocyturia values associated with class I, II, and III adverse events were 4 x 10(4)/mL, 1.5 x 10(5)/mL, and 3.5 x 10(5)/mL, respectively. No class IV events occurred. The cutoff point indicating treatment cessation for adverse events was leukocyturia of 8.6 x 10(4)/mL., Conclusions: These results suggest a link between adverse events and efficacy during BCG maintenance therapy. Leukocyturia appears to correlate with both efficacy and tolerability in this setting. Prospective randomized studies are required to evaluate leukocyturia as a basis on which to adapt the BCG instillation schedule to individual patient susceptibility.

- Abstract
Objectives: The management of complete or partial urethral disruption is controversial, and much debate continues regarding immediate versus delayed definitive therapy. We further analyze our experience and long-term results using early endoscopic realignment., Methods: Between April 1987 and January 1999, 29 men with posterior urethral disruption (23 complete and 6 partial) underwent primary urethral realignment 0 to 8 days after injury. Pelvic fractures were present in 23 patients. In all patients, the actual operating time for realignment was 75 minutes or less. All patients were evaluated postoperatively for incontinence, impotence, and strictures., Results: After a mean follow-up of 68 months (range 18 to 155), all patients were continent. Four patients (13.7%) required conversion to an open perineal urethroplasty. At the last follow-up visit, 25 (86%) of the 29 patients were potent and 4 achieved adequate erections for intercourse using intracorporeal injections (prostaglandin E(1)). Twelve patients (41%) developed short secondary strictures and were successfully treated with internal urethrotomy. The mean follow-up of these 12 patients was 83 months (range 34 to 120). Urinary flow rate measurement at the last follow-up visit revealed satisfactory voiding parameters in all patients., Conclusions: Primary endoscopic realignment offers an effective method for treating traumatic urethral injuries. Our long-term follow-up provides additional support for the use of this technique by demonstrating that urethral continuity can be established without an increased incidence of impotence, stricture formation, or incontinence. In case of failure, endoscopic realignment does not compromise the result of secondary urethroplasty.

- Abstract
Objectives: The most frequent urologic complications after renal transplantation involve the ureterovesical anastomosis (ie, leakage, stenosis, and reflux), with a frequency of 1% to 30% in different series. We present the results of pyeloureterostomy using the recipient's ureter., Methods: From 1988 to 1996, 570 cadaveric renal grafts were performed at our institution. A Lich Gregoir ureterovesical anastomosis was used in every case. Complications involving the anastomosis occurred in 19 cases (3.3%), with 10 stenoses (1.7%), 6 cases of leakage (1.1%), and 3 of reflux (0.5%). The mean donor age was 36.2 years, and the mean duration of cold ischemia was 29.4 hours. The mean recipient age was 41.3 years. Corrective surgery was performed 0.09 years (range 0.01 to 0.22) after transplantation for leakage, 1.13 years (range 0.14 to 5.11) for stenosis, and 5.55 years (range 0.51 to 9.71) for reflux. The recipient's ureter was stented with a ureteral catheter before median laparotomy, except in 3 cases of early leakage (less than 3 days). The recipient's ureter was cut, without the need for ipsilateral nephrectomy, and sutured to the graft pelvis. A nephroureterostomia stent (Gil Vernet stent) (12 cases) or a double J ureteral stent (7 cases) was used for urinary drainage., Results: One graft was lost on day 1 through renal vein thrombosis. Percutaneous nephrostomy was performed on day 2 to clear an obstruction of the double J ureteral stent in one case, and a double J ureteral stent was inserted on day 2 because the nephrouretrostomia stent was incorrectly positioned in another case. Pyelographic controls on day 15 were normal in every case. The mean follow-up was 2.25 years (range 0.24 to 6.1) (2.9 years for leakage, 2.08 years for stenosis, and 1.44 years for reflux). One patient died with a functional graft 3 years after surgery. One graft was lost 4 years after surgery through chronic rejection. There were no complications affecting the ipsilateral kidney. No further ureteral complications occurred after surgery. The mean creatinine level 3 years after surgery was 1.59 mg/dL., Conclusions: Pyeloureterostomy is a safe and permanent treatment for complications of ureterovesical anastomosis and gives excellent results. The technique requires stenting of the recipient's ureter and graft drainage with a nephroureterostomia stent or a double J ureteral stent.

- Abstract
Objective: To determine the value of positive sextant biopsies in assessing the location of prostate tumors within radical prostatectomy specimens and to determine if prostate weight influences the results., Methods: From 1988 to 1996, 166 radical prostatectomies were performed for localized prostate cancer diagnosed by means of ultrasound-guided sextant biopsies. The location of the biopsies was compared with that of tumor tissue within the radical prostatectomy specimen., Results: Of the 996 biopsies, 331 (33%) were positive. The correspondence between the location of the biopsies and that of tumor tissue in the surgical specimen was found to have a sensitivity of 39.4%, a specificity of 81.5%, a positive predictive value of 83.3%, negative predictive value of 36.4% and an accuracy of 52%. For prostates weighing < and >/= 45 g, the sensitivity was 39.9 and 38.9%, the specificity was 88 and 77.2%, the positive predictive value was 90.8 and 76.1%, the negative predictive value was 34.9 and 39.8%, and the accuracy was 52 and 52%, respectively., Conclusion: Negative biopsies do not predict a lack of tumor tissue in the corresponding prostate site after radical prostatectomy, and had less value than positive biopsies for prognostic staging before radical prostatectomy. Results of sextant biopsies are more significant for prognosis before radical prostatectomy when positive. Prostate weight influences the interpretation of the results of sextant biopsies.

- Abstract
Close urologic follow-up of renal transplant candidates and recipients often reveals prostate carcinoma at an early stage. Two patients who underwent renal transplantation for end-stage disease also underwent radical perineal prostatectomy for localized prostate carcinoma, 3 years after grafting in 1 patient and 4 years before grafting in the other. The perineal approach to prostatectomy may facilitate later renal transplantation and avoid allograft damage.

- Abstract
Objectives: Routine sextant biopsies have proven useful in the diagnosis and local staging of prostate cancer. A single positive biopsy is more frequently associated with a smaller tumor and a low risk of positive margins. Nevertheless, the risk of positive margins in patients with 1 positive sextant biopsy remains high (20%). A better assessment of local invasion is therefore needed. In addition to standard sextant biopsies, we routinely obtain 3 additional mid biopsies from the apex to the base of the prostate. The aim of this study is to analyze the contribution of these 3 additional mid biopsies to local staging., Methods: From 1988 to 1996, 177 men underwent sextant biopsies plus 3 additional mid biopsies prior to radical prostatectomy; 59 men had 1 positive sextant biopsy, and 13 also had 1-3 positive mid biopsies. The pathological results of the prostatectomy specimens from these 13 men (group A) were compared with those of the 46 men with only 1 positive sextant biopsy (group B), by means of the Fisher and Mann-Whitney tests., Results: The two groups were similar in terms of age, preoperative prostate-specific antigen, the Gleason score of positive biopsies, the weight of the specimen, the Gleason specimen score, tumor volume and pathological stage. Positive surgical margins were found in 53.8% of group A and 19.4% of group B patients (p = 0.002). The location of the positive additional biopsies matched that of the positive surgical margins., Conclusions: Additional mid biopsies improve the local assessment of prostate cancer in patients with a single positive sextant biopsy, identifying significantly more positive margins when these additional mid biopsies are positive and indicating the location of the positive surgical margins. These informations could be helpful to avoid positive surgical margins during radical prostatectomy.
