[Hemospermia].

Haemospermia is a relatively frequent symptom in urology, especially in young subjects. It is often benign, but is important because of the anxiety it can cause to the patient. The predominant aetiology of haemospermia is prostatic and seminal vesicle disease. Iatrogenic aetiologies, generally without severity, are due to the development of instrumental diagnosis and treatment in urology. Recent progress in the field of medical imaging, particularly transrectal ultrasonography and magnetic resonance imaging, has greatly contributed to the diagnostic and therapeutic approach to haemospermia.

[The AMS 800 sphincter in urinary incontinence after prostatic surgery. Apropos of 16 patients].

OBJECTIVE: To present the results of a series of artificial sphincters implanted for urinary incontinence after prostatic surgery. PATIENTS AND METHODS: From 1987 to 1996, artificial sphincters were implanted for urinary incontinence after prostatic surgery, consisting of one transvesical prostatectomy, 11 prostatic resections and 4 radical prostatectomies. All these patients were evaluate by urine culture, cystourethrography and urethrocystoscopy. Eleven patients underwent urodynamic assessment. The AMS 800 artificial sphincter was used. RESULTS: The mean interval between onset of incontinence and implantation was 18 months. The mean follow-up after implantation of the sphincter was 6 years. An operative wound of the bulbar urethra did not prevent implantation of the sphincter, but required repair and prolonged catheterization (12 days). The mean duration of catheterization was 6 days. The overall functional result was 81% (13 case), and 75% of sphincters were functional at 5 years. Five revisions were necessary to maintain functioning of the sphincter in 2 cases of rupture and 1 displacement of the balloon, 1 case of urethral atrophy and 1 rupture of the pump. Three explanations, 2 total and 1 partial, were performed. Two reimplantations were performed after 12 months and 26 months respectively. CONCLUSION: The AMS 800 artificial sphincter currently represents an effective treatment for urinary incontinence due to sphincter insufficiency after prostatic surgery. However, an old artificial sphincter may require revision to restore function.

[A rare cause of retroperitoneal fibrosis: actinomycosis].

The authors report a case of retroperitoneal fibrosis secondary to actinomycosis with consequences on the urinary tract. They insist on the difficulty of diagnostic, the antibiotic's sensibility and the evolution towards fibrosis which can lead to renal function deterioration.

[Internal drainage by double J ureteral stents. 91 cases].

Urinary drainage by indwelling double J ureteral stent is well documented in the urologic literature. We used these stents in 91 patients. The majority of stents were placed endoscopically (68%). Indications were: -Ureteral obstruction (39 cases) such as tuberculous ureteral strictures, obstruction due to urolithiasis and pelvic malignancies. -Upper urinary tract surgery (29 cases) mainly pyeloplasty, pyelolithotomy, ureterovaginal fistula repair and ureteroneocystostomy. -Adjunct to endourologic treatment (16 cases) such as ureteroscopy and endopyelotomy. -Preparation for extracorporeal lithotripsy (7 cases). The complication rate associated with placement of double J stents was minimal (6.6%). The major complication was migration (3 cases). The average drainage time was 5.8 weeks. In view of these results we conclude that double J stent is safe, effective and has minimal complications.

[Prostate specific antigen].

Prostate specific antigen is the "gold standard" prostate tissue marker. Based on a reviews of the literature, we present the metabolism, method and lassay clinical use for diagnosis, staging and prostate cancer as well as for monitoring response to treatment. The authors also discuss some situations able to increase the level of this marker.

[Diagnostic and therapeutic aspects of suburethral diverticuli. Apropos of 9 cases and review of the literature].

Nine female patients with a urethral diverticulum were admitted to our center over a six period: The clinical symptomatology was not specific. The diagnosis has been performed by voiding and retrograde cysto-uretrogram. The surgical treatment consisted in the excision of the diverticula, with the patient in the supine position. No perioperative morbidity was observed.

[Surgical treatment of iatrogenic stenoses of the ureter. Apropos of 17 cases].

OBJECTIVE: Assess the surgical treatment of iatrogenic stenosis of the ureter. METHODS: Seventeen cases of iatrogenic stenosis of the ureter operated between 1991 and 1995 were reviewed. There were 10 women and 7 men, mean age 52 years with pelvic (n = 12), iliac (n = 4) and lumbar (n = 1) stenosis. Ten persons had ureterovesicular reimplantation, including 6 with psoic bladder, 2 with homolateral ureteroureterostomy and 5 with ureteroileoplasty. Mean follow-up was 24 months. RESULTS: Treatment was successful in 14 patients. There were 3 failures, 2 recurrences with reflux which were treated by reoperation with success. CONCLUSION: Our results were in agreement with those reported in the literature. Classical surgery gives sur results in case of endourologic treatment of iatrogenic stenosis of the ureter.

[Prognostic factors of renal adenocarcinoma: study of a series of 233 patients].

OBJECTIVE: To identify certain prognostic factors of renal cell carcinoma in a retrospective series of 233 patients. PATIENTS AND METHODS: 233 patients (162 males and 71 females with a mean age of 60 years) were operated for renal cell carcinoma between January 1980 and December 1991. sith a mean follow-up of 41.7 months. Statistical analysis was performed according to the Kaplan-Meier method for survival curves, according to the Mantel-Cox model for univariate or multivariate analysis and according to Student's t test and Chi-square test for comparison of quantitative and qualitative variables. RESULTS: The operative and global mortality was 2.2% and 28%, respectively. The following prognostic factors were identified: visceral metastases (p = 0.0001), lymph node invasion (p = 0.001), symptomatic nature of the tumour (p = 0.0004), local pathological stage (p = 0.0001) and nuclear grade (p = 0.0001). Multivariate analysis showed that the first 3 factors were the most pejorative (relative risk (RR) = 6.7, 4.6, and 1.7, respectively). Venous invation, multifocal tumours, and cell type were not studied in our series. CONCLUSION: This study confirmed that metastases, lymph node invasion and symptomatic tumours were the most pejorative prognostic factors.

[Role of ultrasound lithotripsy in the treatment of lithiasis of the lower urinary tract. Apropos of 38 cases].

Between February 1989 and February 1994, 38 patients with lower urinary tract lithiasis were treated by ultrasonic lithotripsy. Mean size of the stone was 23 x 19 mm, extreme being 5 mm-50 mm (over 20 mm in 27 patients). Transurethral lithotripsy has been performed in 36 patients, and percutaneous cystolithotripsy in 2 patients. Some desintegration was complete in 37 cases, and the only failure was a case in which the stone was too hard. Morbidity was zero. Ultrasonic lithotripsy for urethral and bladder stones appears to be a safe, effective and simple method of treatment.

[Ureterovaginal fistulas: treatment with preservation of the distal ureteral segment. Apropos of 3 cases].

The authors report on the treatment of 3 ureterovaginal fistulas using a method preserving the segment of ureter below the fistula. In one case, the fistula was successfully managed by ureteroscopic placement of ureteral stent. Two other cases were managed with ipsilateral ureteroureterostomy, where the segment of ureter below the fistula was identified using ureteroscopic perforation of this segment.

[Sclerotherapy with Betadine for simple cysts of the kidney. Apropos of 7 cases].

The authors report on 7 cases of benign, symptomatic renal cysts treated by percutaneous sclerosis using Betadine solution. The mean size of the cysts was 8 cm and we obtained progressive collapse of all of them. This technique was a simple and effective methode with good results. Indeed, 85% of the cysts disappeard, and only one patient retained a small asymptomatic residual cavity.
