[Seminal vesicle cyst with renal agenesis].

OBJECTIVES: To describe 8 additional cases of seminal vesicle cyst associated with renal agenesis, an uncommon condition arising from anomalies occurring during embryonal development of the genitourinary system, and to analyze the utility of the different diagnostic imaging techniques. METHODS: A retrospective study was conducted on 8 patients to determine the diagnostic possibilities of US (abdominal/transrectal), CT, MRI, urography, cystourethrography and cystoscopy. Transvesical percutaneous punction and deferentography, which permit diagnosis of blind-ending ureter, were utilized in two patients. RESULTS: 75% were left-sided and the age at presentation was generally between 25 to 45 years. The clinical features were related with irritative voiding symptoms, perineal discomfort and ejaculatory disorders. Treatment was based on the clinical features; 3 patients underwent resection via the abdominal retrovesical approach and 5 patients were treated conservatively. CONCLUSIONS: Congenital seminal vesicle cyst may not be as uncommon as it is presumed to be and should be suspected in patients with solitary kidney and voiding disorders. The findings on pelvioabdominal US may suffice to suspect this condition. Although many diagnostic imaging techniques are available, blind-ending ureter can only be diagnosed by transvesical or transrectal percutaneous punction and deferentography. Treatment of symptomatic cases is by surgery, although conservative treatment is utilized more frequently.

[Fournier's gangrene. Presentation of 5 cases and review of the literature].

Five cases of Fournier's gangrene that had been treated at our department over the last five years are described. The literature is reviewed with special reference to the pathogenic, microbiological and therapeutic aspects of this disease entity. Similarly, we underscore the significant drop in mortality with the availability of antibiotics.

[Inguino-scrotal bladder hernia].

We report on a 61-year-old patient with massive scrotal herniation of the bladder and non-Hodgkin malignant lymphoma. We briefly describe this disease entity and its form of presentation, and discuss its diagnosis and treatment.

[Urethral diverticulum in the male].

We report on a 50-year-old male patient with acquired urethral diverticulum complicated by calculus in the anterior urethra. The etiologic factors, the hypotheses put forward relative to the pathogenesis of urethral diverticulum, its diagnosis and forms of treatment are discussed.

[Neurogenic bladder secondary to herpes zoster. Urodynamic evaluation].

A case of urinary retention from infranuclear neurogenic bladder secondary to perineal herpes zoster infection is described. We discuss the different urological compromise (neurologic and vesico-prostatic) following herpes zoster infection and the importance of correct diagnosis and patient follow-up. We do not recommend instituting drug therapy. Intermittent use of a catheter is advocated as the only treatment modality for this condition, which is reversible in most of the cases.

[Epidermoid carcinoma in the renal pelvis].

A case of epidermoid carcinoma of the renal pelvis is described. The etiologic, prognostic and therapeutic aspects of this uncommon tumor of the upper urothelium are discussed.

[Ureteral diverticula. Apropos of 2 cases].

Two cases of unilateral ureteral diverticulum are reported, one of which was associated with a bifid ureter. In the first case, this anomaly was incidentally discovered during a urographic work up of a patient with colic nephritis. In the second case, the presenting symptom was hematuria which was finally attributed to ureteral diverticulosis. A structural classification of these anomalous lesions is described, and the commonly associated conditions (obstruction, infection) are reviewed. The authors do not advocate treating these anomalies.

[Isolated angiomyolipoma of the kidney].

We report on four cases of renal angiomyolipoma. Treatment was by conservative surgery in two cases, and regular control for the remaining two cases. The different diagnostic methods and therapeutic modalities are discussed.

[Giant calculus in a diverticulum of the anterior urethra].

A case of lithiasis in a front diverticulum of the urethra in male is presented. The unusual presentation it had together with the lack of frequency was pointed out, commenting briefly the diagnostic methods and ways of treatment.

[Transitional cell carcinoma in a retrocaval ureter].

We report a case of duplicated inferior vena cava and right retrocaval ureter with a urothelial tumor. The embryonal, clinical and diagnostic aspects of this disease entity are discussed. CT permitted noninvasive visualization of the retrocaval ureter and the urothelial tumor. We underscore the usefulness of the foregoing imaging technique versus the more invasive techniques such as cavography and ascending pyelography.
