Epidemiology of prostatic cancer.

The worldwide incidence of prostatic cancer derived from data published by the Union Internationale contre le Cancer and the International Red Cross Committee has been estimated to be 200,000 new cases each year. Cases occur predominantly in the USA (75 per 100,000) and in northern Europe (40 per 100,000), whereas the incidence is low in Asia. Comparison of clinical series and autopsies confirms the high incidence of cancer in older age groups, although not all cases are seen clinically. Mortality increases more slowly than the incidence of the disease, indicating that diagnosis and treatment are increasingly effective. Aetiological factors remain the subject of much discussion, without any criteria appearing to be dominant.

[Ureteral endometriosis].

Endometriosis, initially believed to be a gynecologic disease, occasionally involves the urinary bladder, and less frequently the ureters. Use of ureteral stents with an appropriate hormonal treatment can obviate the need for open surgery.

[Failures observed after repair of the pyeloureteric junction in children based on a series of thirteen cases].

We report a series of 13 infants with failed surgery for pyeloureteric junction (PUJ) obstruction. Failure was defined as the necessity for further surgery, either refashioning of the anastomosis or nephrectomy. These infants were part of a series of 306 with 322 PUJ. Of the 258 surgically treated infants, 232 (90%) had a post operative course without complication or need for reoperation. The failure rate was significantly higher in infants operated before the age of 4 months (8/65: 12.3%) when compared with those over 4 months of age (5/193: 2.59%). The use of postoperative drainage via a nephrostomy significantly reduced the percentage of early complications (e.g. fistula) but did not affect the final failure rate. The severity of the obstruction at presentation correlated with a bad outcome after reoperation. Of the cases which resulted in failure after reoperation (7/258: 2.7%) all occurred in cases of severe obstruction with parenchymal damage. While the failure of surgery is often evident early (persistant fistula, urinoma, non-functioning kidney on IVP) this may only become obvious some years later. Reoperations were successful in half the cases irrespective of the time between the initial operation and the reoperation. Long term follow-up of all infants operated for PUJ obstruction is recommended.

[Treatment of traumatic rupture of the urethra. Apropos of 30 patients].

Thirty patients with traumatic rupture of the urethra were treated in the Urology Department of Cochin Hospital between 1975 and 1985: 11 as an emergency procedure, 7 for an early complication and 12 for a late complication. In the patients treated early, urethrorrhaphy or one-stage urethroplasty gave the best results. Two stage urethroplasty constituted best treatment for patients with a complication of earlier treatment. In patients with late complications, endoscopic urethrotomy is rarely sufficient on its own and two-stage urethroplasty is generally indicated.

[Failures observed after repair of the pyeloureteral junction in children. Apropos of 13 cases].

We report a series of 13 infants with failed surgery for pyeloureteral junction (PUJ) obstruction. Failure was defined as the necessity for further surgery, either re-fashioning of the anastomosis or nephrectomy. These infants were part of a series of 306 with 322 PUJ. Of the 258 surgically treated, 232 (90%) had a post operative course without complication or need for reoperation. The failure rate was significantly higher in infants operated before the age of 4 months (8/65: 12.3%) when compared with those over 4 months of age (5/193: 2.59%). The use of postoperative drainage via a nephrostomy significantly reduced the percentage of early complications (e.g. fistula) but did not affect the final failure rate.

[Retrograde ejaculation following a Y-V plasty of the bladder neck carried out during childhood. Treatment using the Abrahams procedure].

Retrograde ejaculation of Y-V plasty of the bladder neck performed during childhood appears to be a rare complication. Based on a case treated with success, the authors stress the need for non-aggressive treatment of bladder neck disease in children (endoscopic radial incisions). The procedure proposed by J.J. Abrahams for the treatment of retrograde ejaculation (simple calibration of the bladder neck and posterior urethra) proves to be reliable, although recurrences may occur.

[Lymphography with lymph node puncture biopsy. A reliable procedure for assessing the lymphatic spread of bladder tumors].

119 patients with bladder tumors of category Ta, Tis, T4, considered for radical treatment because of local conditions were studied by pedal lymphography (LAG) and percutaneous fine needle aspiration biopsy (FNA). 41% had a positive LAG. Adequate material was obtained for FNA in 94% of the patients. Of 70 patients with normal LAG none had a positive FNA; only 36% of those with a positive LAG had a positive FN. The high rate of positive LAG with negative FNA is attributed to inflammatory changes due to previous transurethral resection. Radical lymphadenectomy (LND) was done in 64 patients of whom 54 had a negative FNA. In this group, 8 (17%) had a positive LND. There was no mortality and morbidity was mild. LAG with FNA has a role in the pre-operative staging of bladder carcinoma.
