Affirmative action at work: a survey of graduates of the University of California, San Diego, Medical School.

Reported here are the results of a mail survey of 113 graduates from the University of California, San Diego, School of Medicine. Fifty-seven had been admitted with assistance of the Special Admissions Subcommittee (SAS) and 56 had been admitted through the traditional Recruitment and Admissions Committee mechanisms. SAS graduates see more patients daily, and practice more often in primary care specialties in rural and inner-city areas, providing medical care for ethnic minorities from lower socioeconomic strata.

[Renal angiomyolipoma: study of 39 patients and general review].

Between 1969 and 1991, 39 patients totalling 48 renal units with renal angiomyolipoma (RAMP) were diagnosed and treated in the Urology Service of the Hospital La Paz. In 5 patients, RAMP was part of a tuberous sclerosis, and was isolated in the remaining ones. RAMP was symptomatic in 32 cases (32/48 = 66.6%), 10 with Wundrelich's syndrome, and in 24 cases (24/48 = 50%) was larger than 4 cm. In the first cases of our series, clinical diagnosis through renal arteriography was achieved in 33% (5/14) cases; later, with the arrival of ultrasound and CAT, pre-operative diagnosis was possible in 88% (30/40) of cases. There was also 2 periods with regard to treatment, the initial one with predominance of radical surgery and the present one of observation and/or conservative surgery depending on size as well as signs and symptoms. Overall, 23 nephrectomies, 2 partial nephrectomies and 6 tumorectomies were performed, while there has been 17 cases (with no histological confirmation) treated with conservative approach and followed-up with ultrasound and CAT. With an average follow up of 8.4 years (range: 0.5-20 years), there has been no local or metastatic relapse of RAMP. There was one case of lymphatic affection which was explained as evidence of RAMP's multifocal condition and not as an indication of malignancy. In 3 patients, histological examination revealed coexistence of RAMP and renal carcinoma; 2 of these patients who underwent nephrectomy are free of disease; the third patient, treated with conservative surgery (tumorectomy), showed renal carcinoma relapsed after 2 years and had it removed. RAMP's incidence, histogenesis, diagnostic methods and treatment criteria are discussed.

[Multilocular renal cyst: clinico-pathological considerations apropos of a case and review of the literature].

A case of multilocular renal cyst (MRC) is reported in a hypertensive patient in whom the IVP had disclosed a left renal mass. The ultrasound and CT workup revealed a well-defined, solid renal mass that was angiographically hypovascular. Cytologic examination of the specimen obtained by fine needle aspiration biopsy yielded no conclusive data. A left radical nephrectomy was performed. The histologic diagnosis was that of multilocular renal cyst. At 42 months the patient remains hypertensive with no evidence of tumor recurrence. We discuss the diagnostic criteria of MRC and the difficulty in making the differential diagnosis from renal carcinoma, and describe the histologic features of MRC that permit us to distinguish this disease entity from other renal tumors or dysplastic disease with different biologic significance.

[Evaluation of extravesical ureteroneocystostomy in kidney transplantation].

The present study evaluates extravesical ureteroneocystostomy, the technique used for reconstruction of the urinary tract in 120 kidney transplants. The urological complications ascribable to this technique were observed in 10% (12/120) and consisted of urinary extravasation (10), and ureteric obstruction (2). The treatment of the foregoing complications, which was successful in 8 cases, is described. The indications and advantages afforded by this technique in renal transplantation are discussed.

[Intra-diverticular adenocarcinoma of the urethra in women].

We report on a female patient who presented with urethrorrhagia and a palpable urethral mass which was diagnosed as urethral diverticulum, the site of a tumor that proved to be adenocarcinoma of the urethra. The patient underwent radical urethrectomy and pelvic and inguinal lymphadenectomy. Urethral reconstruction was performed using a vesical flap following the technique described by Tanagho. Thereafter, she received 6 courses of M-VAC polychemotherapy. Diverticulum and carcinoma of the female urethra are uncommon. Adenocarcinoma is the most common tumor type encountered in these diverticula. Diagnosis is clinically simple and treatment is by radical surgery and radiotherapy. The foregoing treatment modalities have improved patient survival when the tumor is detected early. This tumor type is particularly aggressive and outcome depends on tumor stage.

[Vesical actinomycosis: rare tumor of the urachus].

A female patient of child-bearing age using an intrauterine device (IUD) consulted our department for a hypogastric mass which turned out to be actinomycosis of the bladder. Antibiotic treatment resolved the infection and removal of the inflammatory mass was unwarranted since infected fistulous tracts had been observed. There appears to be a causal relationship with IUDs, as in genital actinomycosis. Due to the increasing use of contraceptive devices, we are likely to find this type of infection, which might be difficult to distinguish from malignant disease, increasingly frequent in urologic practice.
