[Lymphangiomyomatosis: an exceptional cause of chyluria. Report of a case].

A rare case of lymphangiomatosis without pulmonary involvement is reported. The diagnosis was based on the presence of multifocal lesions and histological examination. Retroperitoneal lesions were responsible for chyluria, which was treated surgically. Chyluria is an exceptional complication of this disease, as only 3 such cases have been reported in the literature. The presence of cutaneous signs raises the question of the relations between lymphangiomatosis and Bourneville's tuberous sclerosis.

[Treatment of interstitial cystitis with sub-trigonal cystectomy and enterocystoplasty].

Eight patients with interstitial cystitis were treated by supratrigonal cystectomy and enterocystoplasty. The indications for this procedure are functionally disabling interstitial cystitis refractory to conservative treatment and associated with severely altered cystomanometric parameters. 6 patients obtained an excellent functional result and 2 patients obtained a poor result, due to sphincter hypotonia responsible for total incontinence in one case.

[Surgical treatment of renal cancer in adults].

The curative cell carcinoma is surgery and consists of a radical nephrectomy. Pre-operative assessment must be complete. Indications are extensive because nephrectomy allow, even in evaluated forms, a long and comfortable survival. The incidental discovery of renal cell carcinoma is more and more frequent. It allows limited surgery and should be followed by higher survival rates.

Vesicoureteral reflux in the renal transplantation candidate.

The incidence and severity of urinary tract infection episodes were evaluated in two groups of renal transplantation patients. Group 1 consisted of 11 patients transplanted following successful surgical correction of a noninfected vesicoureteral reflux in native kidneys, and group 2 of 28 patients transplanted with a noninfected vesicoureteral reflux. An increased incidence of acute urinary tract infection episodes was noted in group 2 as compared to group 1 (42.8 vs. 18%), with a mean of 2.6 +/- 1.4 episodes per patient in group 2 and 0.5 +/- 0.32 in group 1. Asymptomatic bacteriuria was not statistically different in the two groups (36.4 vs. 25%). In group 2, the incidence of urinary tract infection episodes increased in patients presenting high-grade (3 and 4) reflux in native kidneys. Despite the relatively low number of patients involved, our observations indicate that high-grade vesicoureteral reflux in native kidneys must be operated before transplantation, even when there is no history of urinary tract infections and urine cultures are sterile.

[Post-traumatic stenosis of the membranous urethra].

Secondary urethral stricture is the most serious complication of traumatic rupture of the membranous urethra, directly related to the treatment of the rupture. In a series of 45 patients treated for urethral rupture with a minimal follow-up of 5 years, 30 developed stricture (66%). An urethral guide, inserted in 31 cases, was responsible for the stricture in 26 of these cases (84%). This stricture developed rapidly (average of 7.4 months), whether the initial rupture was complete or incomplete and was longer (average of 35 mm) in the case of complete rupture. End-to-end urethrorraphy performed between the 15th and 35th day in 14 patients was complicated by 4 secondary strictures (28%). The treatment of the stricture depended on the initial treatment of the rupture and the radiological length of the stricture. In the case of stricture secondary to an urethral guide, end-to-end urethrorraphy for a stricture less than or equal to 40 mm (12 cases) and 2 stage urethroplasty for a stricture greater than 40 mm (4 cases) achieved a good result in 68.8% of cases. The strictures secondary to end-to-end urethrorraphy (4 cases) were treated by direct vision urethrotomy (3 cases) with 100% of immediate good results and by urethral telescoping (1 case) complicated stress urinary incontinence.

[Emphysematous pyelonephritis and perinephritis].

The authors report an eighth case of emphysematous perinephritis and a new case of emphysematous pyelonephritis. The general features of these two diseases and their similarities are described: middle aged diabetic women, clinical picture of sepsis, gas images projected over the renal area with delayed excretion on intravenous pyelography, computed tomography reveals the exact site of the emphysematous images (perinephritic and or intraparenchymal). Emphysematous perinephritis may be an early form of emphysematous pyelonephritis. Surgical drainage of the renal compartment allows conservative management at this early stage.

[Varicocele in children and adolescents. Is surgery justified?].

Varicocele, a disease essentially observed in adults, is under-estimated in children and adolescents, in whom, for the majority of authors, the therapeutic management is surgical although the benefits in terms of fertility are unknown. Forty-eight children and adolescents, seen between 1978 and 1983, were followed by clinical examination and subsequent sperm count with a mean follow-up of 5.20 years. The presence at the first examination of the subsequent development of testicular atrophy is a pejorative element in the disease: 12% of children managed expectantly developed left testicular atrophy at puberty associated with severe anomalies of the sperm count. Persistent testicular atrophy after surgery was synonymous with anomalies of the sperm count in all of these children. Regression of moderate atrophy was observed in three children after surgical cure, but the pre and post-treatment sperm counts were normal.

Persistent testicular atrophy after surgery was synonymous with anomalies of the sperm count in all of these children. Regression of moderate atrophy was observed in three children after surgical cure, but the pre- and post-treatment sperm counts were normal.

[Injuries of the posterior urethra. Apropos of 57 patients excluding iatrogenic injuries].

Between 1973 and 1986, 57 patients presented with a fracture of the pelvis with rupture of the posterior urethra. All of these patients were treated as an emergency and were then followed periodically with a minimal follow-up of 2 years. There were 4 cases of rupture of the prostatic urethra and 53 cases of rupture of the membranous urethra, including 32 complete ruptures and 21 partial ruptures. In the case of rupture of the membranous urethra, initial treatment, in 34 cases, was realignment by guiding catheter either immediately (25 cases) or deferred emergency (9 cases) and, in the other 19 cases, end-to-end urethrorrhaphy or urethroplasty (2 cases) as a deferred emergency (15th to 32nd day). The results were evaluated on the maximal flow/second and the flowmetry curve, intravenous pyelography with micturating and post-micturating films and the need for dilatations or reoperations. In the cases treated by realignment by guiding catheter, 28 of our 34 patients (82%) developed secondary stenosis which is difficult to treat because of the large amount of granulation tissue and fibrosis, although the best results were obtained by end-to-end urethrorrhaphy (75%). In contrast, repeated dilatations and optical urethrotomies were failures. Deferred emergency end-to-end urethorrhaphy, in 17 cases, ensured a good immediate result in 60% of our patients. Secondary stenosis (7 cases) was always short and easily accessible to optical urethrotomy.(ABSTRACT TRUNCATED AT 250 WORDS)

[The prevention of the recurrence of stage pTa bladder tumors using intravesical instillation of BCG].

45 patients were included in a retrospective study designed to assess the long-term efficacy and tolerance of immunotherapy by intravesical BCG instillation in the treatment of stage pTa bladder tumours (mean follow-up 52.7 months, range: 12-87 months). 41 patients (91% responded to immunotherapy: 24 (53%) did not develop anu recurrences with a mean follow-up of 49.4 months (range: 19-87 months) and 17 (37.7%) were improved by treatment as the interval between recurrences was significantly increased. 4 patients (8.8%) failed to respond to BCG therapy with progression to stage pTa G3 vesical papillomatosis in one patient. The local tolerance was poor for twelve patients (26.6%), requiring discontinuation or spacing of the instillations. Other complications such as prostatitis and intense fever were observed. Three patients had persistent disturbances of micturition following treatment in the form of urinary frequency due to the decreased bladder volume. Neither the grade, nor the frequency of recurrences prior to treatment, nor the solitary or multifocal nature, nor the site of the initial tumour appeared to influence the response to BCG therapy and did not constitute independent individual prognostic indicators.
