OBJECTIVE: To present a case of inflammatory pseudotumor of the urinary bladder, with special reference to the differential diagnosis. METHODS/RESULTS: A 26-year-old patient with a history of gross hematuria and voiding syndrome underwent partial cystectomy for a bladder tumor. Pathological analysis disclosed an inflammatory pseudotumor of the bladder. The patient's postoperative course has been satisfactory.
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.

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.
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.

We report on a patient with two primary and synchronous urological tumors (hypernephroma and leiomyosarcoma of the bladder). Patient follow-up of 14 months revealed no evidence of tumor recurrence. The clinical, diagnostic and therapeutic aspects of this rare tumor of the bladder are highlighted. We consider surgical treatment mandatory and radio- and chemotherapy adjunctive treatment modalities.
We report a case of carcinosarcoma whose most striking feature was its markedly chondroid elements that initially prompted us to suspect a chondrosarcoma. The clinical features and treatment of this rare tumor type are briefly discussed.
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.
A case of diverticulum of the female urethra complicated by lithiasis is described. The etiopathogenic aspects, clinical features, diagnostic methods and treatment of this rare condition are discussed.

We present a case of diffuse malignant mesothelioma of the tunica vaginalis testis, a very uncommon tumor site, in a patient who also had a tumor localized to the chest. We could not determine however, whether the testicular neoplasm was a primary tumor or a distant metastasis. We describe this tumor type, its mode of presentation, diagnosis and treatment.
A case of hydatid cyst of the adrenal gland in a patient with a previous history of hydatidosis is described. Following a brief discussion of the pathological features of adrenal cysts, attention is focussed on the diagnosis and treatment of this specific form of adrenal cyst: the hydatid adrenal cyst.
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.
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.
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.
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.
We report a case of bilateral adrenal pheochromocytoma in a young, male patient who consulted for arterial hypertension. The adrenal tumors had been accurately diagnosed by abdominal ultrasonography and confirmed by CT. The incidence of bilateral involvement in pheochromocytoma is briefly discussed and the methods currently utilized for topographic localization of the tumor are described.
