[Epidermoid carcinoma of the penis]. / Carcinoma epidermoide de pene.

Four cases of Penis Epidermoid Carcinoma, three treated with partial amputation and one with Co60 radiotherapy due to the patient's refusal to undergo surgery, are illustrated. After an average follow-up of 14 months (2-24), patients who underwent surgery have not relapsed. Local relapse was observed in the patient given radiotherapy within 6 months.

[Penile prosthetic implant in the treatment of impotence: our experience]. / Implante de prótesis de pene en el tratamiento de la impotencia: nuestra experiencia.

The aim of this study was to review the current situation of penile prostheses in the treatment of erectile dysfunction and to analyze the indications, degree of acceptability and complications in our experience. From 1987 to 1993, 35 implants were inserted in men suffering from impotence due to different etiologies. The mean age was 54 years and the mean duration of erectile dysfunction was 37 months. Diabetes, vascular disease and pelvic surgery were the most common pathologies recorded. We utilized the penoscrotal approach in 97.14% of the cases and implanted the following prostheses: 12 Hydroflex, 7 Uniflate 1000, 6 Acuform, 4 Mark II, 3 Dynaflex and 3 Alpha 1. The mean follow-up was 38 months. Infection of the prosthesis by Staph. epidermidis was observed in 5.71% of the cases. This infectious complication required removal of the prosthesis. Two patients with a Uniflate prosthesis complained of mechanical failure. Eighty percent of the patients and 74.28% of their partners were satisfied with the results. When asked if they would undergo another operation again if it were necessary, 71.42% answered "yes". Penile prostheses have withstood the test of time and continue to be an effective and valid therapeutic alternative in impotent men. Although the complication rate is low, adequate information must be provided to the patient and partner in order to enhance the results.

[Cystic pyeloureteritis. A diagnosis to keep in mind]. / Pieloureteritis quística. Un diagnóstico a tener en cuenta.

OBJECTIVES: Cystic pyeloureteritis is a disease entity of unknown etiology and unspecific symptoms. It is incidentally detected and is difficult to distinguish from other disorders showing filling defects on urographic evaluation. All the foregoing prompted us to report the present case. METHODS/RESULTS: We report a case of cystic pyeloureteritis that had been diagnosed during ureterorenoscopy in a patient with lithiasis and recurrent urinary tract infection. The etiopathogenesis, diagnostic and therapeutic aspects described in the literature are briefly reviewed. CONCLUSIONS: We underscore the importance of confirming the diagnosis by endoscopic and cytological studies. Conservative management is advocated. Patient follow up should include urinalysis, urine culture and cytology twice yearly and intravenous urography once a year.

[Ureteral endometriosis]. / Endometriosis del uréter.

OBJECTIVES: Ureteral involvement due to endometriosis is uncommon. Its silent onset and the progression of ureteral obstruction, if undiagnosed, can lead to the loss of the renal unit. The present case is described to underscore the importance of early diagnosis. METHODS/RESULTS: We report on a patient with obstructive uropathy secondary to intrinsic ureteric endometriosis that had undergone nephrectomy due to parenchymal destruction. One year following resection of the endovesical portion, recurrence in the ureteral stump was observed. The clinical features, the diagnostic and clinical aspects are briefly discussed. CONCLUSIONS: Although ureteric involvement is uncommon, renal function of patients with pelvic endometriosis must be followed closely by analyses, ultrasound and/or intravenous urography for early detection of this condition.
