[Bladder leiomyoma. Review and report of a case]. / Leiomioma vesical. Revisión y presentación de un caso.

OBJECTIVE: The present study reviews bladder leiomyoma, an uncommon pathology. The problems of differential diagnosis and the therapeutic options are discussed and the literature reviewed. METHODS/RESULTS: A 33-year-old female with anterolateral intramural leiomyoma of the bladder is described. Patient evaluation included US, cystography, CT, cystoscopy and ultrasound-guided suprapubic puncture. CONCLUSIONS: Leiomyoma is an uncommon benign tumor of the bladder. To our knowledge, only 235 cases have been reported in the literature. We advocate the use of ultrasound-guided suprapubic puncture, a simple procedure that is frequently diagnostic, in the evaluation of this tumor type.

[Acquired enterovesical fistulas]. / Fístulas enterovesicales adquiridas.

We report on 23 patients with acquired vesicoenteric fistula treated during the past 12 years: 48% of these were of inflammatory etiology (11 cases), 35% were caused by neoplasms (8 cases) and 17% were iatrogenic (4 cases). The most frequent symptoms were pneumaturia and fecaluria (78% of cases). Cystoscopy was the most useful diagnostic procedure in detecting fistula (13 of 18 cases). Other imaging techniques, though less effective for diagnosis, were useful in assessing the status of the GI tract and, at times, in determining the etiology of the fistulae. Treatment depends on the etiology, localization and patient general condition. The technique most frequently applied in our series was resection of the fistulous tract, together with the compromised intestinal segment, and bladder suture.

[Malignant mesothelioma of the tunica vaginalis of the testis]. / Mesotelioma maligno de la túnica vaginal del testículo.

We report a case of malign mesothelioma of the tunica vaginalis of testis in a 84 years-old male. Clinical presentation was hydrocele. Special attention is given to differential diagnosis and therapeuticals possibilities.

[Segmental kidney dysplasia]. / Displasia renal segmentaria.

The frequency of segmental renal dysplasia was studied in 15 patients with complete pyeloureteral duplication whose anatomopathologic diagnosis of the lesions of some of the renal segments of duplication were available (14 partial nephrectomies, one open renal biopsy). Evidence of dysplasia was found in 10 cases (67%), the remaining 5 were diagnosed as having chronic pyelonephritis. All patients had a coexisting ureteric anomaly that drained the dysplastic renal segment: 6 ureteral ectopias, 3 ectopic ureteroceles, 1 vesicoureteral reflux. The clinical and pathogenic importance of the associated anomalies of the excretory tract, the diagnostic difficulties arising from the minimally- or non-functioning dysplastic renal segment, and the therapeutic modalities utilized are discussed.

[Treatment of advanced prostatic carcinoma with ketoconazole. Our experience in 10 cases]. / Tratamiento del carcinoma prostático avanzado con ketoconazol. Nuestra experiencia en diez casos.

We have treated 10 patients with histologically diagnosed prostate carcinoma, in states C and D, with orally administered dosage of 1200 mg./day of ketoconazol, with the following results: Four patients were excluded through displaying gastrointestinal intolerance in the first days of treatment. Three patients treated had the dosage reduced to half due to poor tolerance, but no improvement was noted. Another three patients tolerated the treatment for four months and displayed transitory remission of ostealgia, which permitted the withdrawal of analgesics. In these patients the treatment was suspended due to digestive intolerance and to the appearance of a clinical picture compatible with suprarrenal corex hypoadrenalism.
