The vesical cavernous hemangioma is a rare tumor with a begin biological behaviour. This sort of tumor has particular diagnostic and therapeutical features, and a variety of treatments has been used on it. The case of cavernous hemangioma in the bladder that we present was only diagnosed after RTU due to preoperative diagnosis of urotelial vesical tumor. We review clinical, diagnostic and therapeutical features of this kind of tumor.
Our experience in the use of the double-J catheter in the prevention and treatment of urinary obstruction in stone disease is presented. This retrospective study spans the period January, 1985 to June 1989. Fifty-five double-J catheters were placed in 51 patients (catheter replacement was required in 4). Catheter placement was done antegradely in 17, retrogradely in 34 and intraoperatively in 4 cases. The indications were for treatment post-ESWL in 45 patients, stone remnants following percutaneous nephrolithotomy in 1, post-ureteroscopy in 2, and after open surgery in 2 patients. Complications were observed in 24% of the cases, hematuria being the most common complication. The foregoing agrees with the 20-40% complication rate reported in the literature. Thus, we can conclude that the double-J catheter is well-tolerated and is a simple yet useful endourologic tool in the prevention and treatment of urinary obstruction in stone disease.
The present study was performed in ten cases of hyperparathyroidism with a history of recurrent renal colic with or without passing calculi. Most of these patients had undergone stone surgery. Diagnosis was based on patient history, and metabolic and radiologic work up, and confirmed histologically following surgical exploration of the neck and removal of the pathologic parathyroid gland.

We report a case of nephrogenic adenoma in a patient who had previously undergone a nephrectomy procedure for renal TB, and with a history of recurrent infection of the urinary tract. The present case shows the role of chronic inflammatory disease in the pathogenesis of nephrogenic adenoma.
