[Intracavernous injections].

Virag's paper concerning erection induced by intracavernous injection of papaverine was published 10 years ago, in 1982. Since this time, several substances have been tested; some have been abandoned, while others have demonstrated their efficacy and relative safety. After briefly recalling the physiology of erection and the principal substances used (papaverine, phentolamine, moxisylyte, PGE1, ceritine and VIP), the indications for intracavernous injection are reviewed in the context of investigation and treatment of certain forms of impotence. Lastly, the injection technique, the results and the complications are discussed, with emphasis on the ways to prevent or treat these complications.

Bladder reconstruction with ileum after cystoprostatectomy for bladder cancer: analysis of the micturition and continence of 44 consecutive patients.

From October, 1987, to August, 1990, 47 patients underwent an ileal low pressure bladder replacement using the Hautmann procedure after radical cystoprostatectomy for bladder cancer. The qualities of micturition and continence were evaluated from a questionnaire mailed to the patients and by urodynamic examinations in 44 consecutive patients over a follow-up period of more than 3 (mean 10.7) months. The 44 patients (100%) were perfectly dry during the daytime and voided every 4 (2-6) h with a micturitional volume of 357 (200-500) ml. Forty-two of the 44 patients had no residual urine. Thirty-three of the 44 patients (75%) were perfectly dry at night with a voiding frequency of 1.5 (0-3). Seven of the 44 patients (16%) were occasionally incontinent (spotting less than 2/week). Four of the 44 patients (9%) had night incontinence and used as external device. Only two patients showed high pressure waves of greater than 50 cm H2O. The maximum urethral pressure was 59.07 +/- 13.6 (30-80) cm H2O. The maximum flow rate was 17.2 +/- 9.7 (4.5-35) ml/sec. The different factors responsible for the new micturitional balance were discussed. With its very good functional results and its ease of performance, the ileal neobladder is, for us, the procedure of choice for bladder reconstruction after cystectomy.

Antibiotic prophylaxis with cefotaxime in endoscopic extraction of upper urinary tract stones: a randomized study. The Cefotaxime Cooperative Group.

This French multicentre, placebo-controlled, double-blind study investigated the efficacy of a single dose of cefotaxime 1 g iv in the prophylaxis of patients undergoing endoscopic extraction of urinary tract stones. Postoperative fever occurred in 12 patients in the placebo group and in nine in the cefotaxime group (no significant difference). The incidence of postoperative bacteriuria, between the first and third postoperative day, was significantly higher in the placebo group (15/60, 25%) than in the cefotaxime group (5/60, 8.5%). This controlled study clearly demonstrates the efficacy of antibiotic prophylaxis in endourological procedures. Cefotaxime significantly reduced the incidence of early postoperative bacteriuria without causing any significant side effects.

Total androgen blockade with Zoladex plus flutamide vs. Zoladex alone in advanced prostatic carcinoma: interim report of a multicenter, double-blind, placebo-controlled study.

A double-blind, placebo-controlled, randomized, multicenter study was undertaken to investigate the effects of Zoladex plus flutamide vs. Zoladex plus placebo in patients with advanced prostatic cancer. Interim analysis has revealed no differences between the 2 groups in objective or subjective responses at 6 months' follow-up or in overall survival and time to disease progression at 15 months' follow-up.

[Synchronous bilateral cancer of the kidney in the adult. Apropos of a case].

Following a case of synchronous bilateral renal cancer, we carried out a review of the literature and defined the specific therapeutic and prognostic characteristics of this clinical condition. Conservative surgery should be proposed as first line treatment. Results in terms of survival depend on the histological characteristics of the more affected kidney. The prognosis is relatively good in general and better than that of unilateral cancer.

[Preoperative evaluation in urology. A reassessment].

Routine preoperative screening tests are questioned more and more often. A prospective study of preoperative screening in a Urologic unit was performed and was correlated with the patient's outcome. With the agreement of the anesthesiologists team, we think we could abandon chest X ray, and CBC and could restrict ECG immuno-hematologic and clotting tests to patients with intraoperative hemorrhagic or cardiac risk. Finally any other tests, creatinine, SMA, urinalysis, urine culture should only be prescribed, according to the patient's specific clinical context.

[Left-sided inferior vena cava: source of peroperative difficulties in nephrectomy of a horseshoe kidney with pyonephrosis].

A case of left-sided inferior vena cava, discovered intra-operatively, is reported. The authors consider that the operative risk associated with this anomaly could have been avoided by preoperative ultrasonographic localisation of the vessel. They recommend that ultrasonographic localisation of the inferior vena cava should be an integral part of every renal ultrasonography examination.

[Renal insufficiency caused by prostatic cancer. Apropos of 7 cases].

Prostatic carcinoma was discovered in seven patients presenting with renal failure, with ages ranging from 44 to 84. Management consisted of various associations of estrogens, steroids, hemodialysis, TUR, ureteral implantation, or ureteral prostheses. Cutaneous ureterostomy was avoided whenever possible. Survival was less than one year for four patients with anaplastic carcinoma, while all the others survived for at least four years. Two different obstructive mechanisms caused the acute renal failure in these patients: simple infravesical obstruction, easily relieved by TUR, and retroperitoneal ureteral obstruction, requiring a more complex operative procedure in hormone dependent patients.

Endoscopic internal urethrotomy for treatment of urethral strictures: midterm survey.

Success in the management of urethral strictures can be claimed only after many years, patients sometimes faring well for ten years or more before suffering a recurrence. We used endoscopic urethrotomy as primary treatment for a variety of urethral strictures in 123 patients. Follow-up is over two years for 63 patients and more than five years for 18. Over-all success rate at five years was 76 per cent. Failures are twice as frequent in strictures, regardless of their origin, involving the anterior urethra than in the bulbar or posterior urethra. Two-thirds occurred in the first year of follow-up, but, as in other techniques, recurrence can occur after four years.
