Gangrène of the male external genitalia (GMEG) is characterized by necrotizing cell evolving toward necrotizing of the soft tissues of the male genitalia and possibly death. The cause may be primary infection called Fournier's gangrene (5%) or secondary infection (95%) due to general or local factors. GMEG is a real urinary emergency because of its local and general complications which lead to death in 20% of cases. Precocious and massive antibiotherapy, a surgery to unbridle and possibly reanimation, oxygenotherapy, urinary diversion or colostomy, are required. We have treated 55 men with this affection from january 1988 to may 1996. Mean age was 58 years (range 20 to 85). The prodromial period was about 12 days. Toxi-infectious shock was noted in 8 patients (14%). Six patients (10%) developed renal acute insufficiency. Lesions were localized to the male external genitalia in 24 cases and stretched to the inguinalis, to the abdomen or to the thorax in 34 patients. The cause was a stricture of urethra in 23 cases (41%) diabetes in 18 cases (32%), anal abscess in 7 cases (13%). No etiology was found in 6 cases (10%). Emergency treatment involved three antibiotics, surgery to unbridle necrotizing tissue in all patients, reanimation in 20 patients (35%), oxygenotherapy in 4 patients (7%), colostomy in 2 cases and urinary drainage in 23 patients (42%). Free skins grafts were necessary in 6 patients (10%), 5 patients (9%) died due to septic shock. On the basis of these observations and a review of the literature, we analyzed the ethiopathogenic, bacteriological and therapeutic aspects of this affection marked by high mortality in spite of therapeutic progress.

We report two cases of grade 1 papillary transitional cell carcinoma which have a distinct pathological. The tumor was infiltrating the lamina propria in the first case (pT1) and the superficial muscle in the second case (pT2). These tumors were composed by nests and tubules with few cytological atypias, making the diagnosis of cancer difficult. The prognosis of these tumors is not well defined.

Peritonitis can result from many causes. We report a case caused by a renal abscess which contaminated the abdominal cavity. A 30-year-old patient was referred with suspected ruptured ectopic pregnancy with signs of peritoneal flooding. The culdocentesis was positive and returned frank pus. Endoscopic exploration with an open laparoscope revealed that the infection did not originate from a gynecological infection but did not identify the exact origin. Laparotomy was performed and revealed a splenic abscess and a subphrenic peritoneal breach releasing a purulent liquid. Splenectomy and abdominal lavage with draining was performed. A post-operative pyelourogram showed a silent kidney with multiple coralliform lithiases. Interventional sonography allowed drainage of a retroperitoneal collection. The post-operative period was uneventful. Left nephrectomy was later performed. Only rare cases of ruptured pyonephrosis leading to peritonitis have been reported, usually with poor prognosis.

Testicular descent is a complex mechanism, appearing at the end of gestation, influenced by mechanical and hormonal factors. Surgical therapy should as soon as possible be done, in order to avoid the risk of degeneration and sterility.

We report one of the first implantations of a definitive ureteral stent, MEMOTHERME, for cicatricial striction of the pelvic ureter in a patient who had undergone left pelvic ureterolithotomy in the 1950s and who later developed homolateral hydronephrosis. The analysis of this case showed that short-term results are excellent in terms of urine flow after exclusive endoscopic installation. The hospital stay is short.

Kidney in ectopic position is dysplasic, and associated to other malformations. The advent of a lithiasis in these conditions rises questions about therapeutic options. We report on five observations of pelvic ectopic kidney with urinary lithiasis. Patients were aged from 16 to 42 years. Kidney was non functional in two cases, or with normal appearance sized 10 to 12 cm. We performed total nephrectomy in two cases, pyelolithotomy in the other cases. Surgical approach was subperitoneal via iliac route. A dismembered pyeloplasty was associated in one case. All patients did well. Radiologic control at 6 and 12 months showed no recurrence in a well functioning kidney. Surgical lithotomy is advocated as a treatment in urinary lithiasis affecting ectopic kidney. It is an easy procedure which permits correction of other associated malformations.

The authors report 1 case of particularly severe reflex neurovascular dystrophy whose clinical course was marked by the discovery of a carcinoma of the prostate. There was improvement in the reflex neurovascular dystrophy despite hormonal therapy of the cancer. Reflex neurovascular dystrophy cannot be considered as a form of a paraneoplastic syndrome.

The authors report 25 cases of scrotal trauma treated between 1977 and 1992. The mean age of the patients was 28 years (17-46). Agressions were the predominant cause (10 cases) followed by traffic accidents (6 cases) and occupational injuries (4 years). Blunt trauma were more frequent (20 cases). A painful, ecchymotic scrotum was the most constant sign; confirmed by ultrasound that better defines the lesions. The surgical exploration was always, indicated and preservation of the gland was possible in 20 patients.

Twenty five patients with symptomatic BPH and normal PSA underwent electrovaporization. The mean IPSS was 21.5 before and 7.8 three months after treatment while the mean peakflow was 7.1 ml/s and became 16.9. With a short hospital stay (3 days) and a very low morbidity, electrovaporization seems to be a good alternative to TURP. A longer follow-up is necessary.
