We report on a 24-year-old female patient with posttraumatic migration of a bony fragment from the site of the fracture to the bladder. The foreign body was removed from the bladder by endoscopy. The etiopathogenic mechanism, clinical signs, diagnostic method and therapeutic management are discussed.
Contribution of one case of Spontaneous Perirenal Haematoma (SPH) secondary to hydronephrosis accompanied by lithiasis in pelvic kidney. SPH can result from multiple causes, the most frequent ones being renal tumours, most particularly angiomyolipoma and hypernephroma. Hydronephrosis is an uncommon cause of SPH, and very few cases are described in the literature. The present paper addresses the diagnostic usefulness of the various radiological tests as well as the therapeutical approach to be followed.
Five cases of fracture of penis with a mean follow-up of 52 months are described. Four underwent early surgical treatment and one was treated conservatively. This latter case developed penile curvature from fibrosis. The literature is reviewed with special reference to treatment. Like most of the authors, we advocate early surgical management as the treatment of choice for rupture of the corpora cavernosa.
Stone formation in the double J ureteral catheter is an uncommon complication that generally appears in patients that are predisposed to stone formation and persistent infection of the urinary tract. We report on a 29-year-old female patient in whom stone formation was observed in both ends of the catheter, less than 3 months after it had been placed. Urine culture was positive for P. mirabilis. Percutaneous nephrolithotomy was warranted in the treatment of the pyelic stone and for removal of the double J catheter. We underscore the importance of doing urine cultures and radiologic control in this patient group and shortening the time the catheter is left indwelling.

A study ia mde of 15 patients with a known neoplasia: 2 retroperitoneal tumours, 5 lymphomas, 3 prostate neoplasias, 3 seminomas and 2 uterus neoplasias; with displacement of the ureter and in some cases ectasia of the excretion system. The displacement was always one-sided and most frequently found in the lower third of the ureter. Ectasia was found in two patients; we have never found this in any patients without a known neoplasia. Adenopathies were the most frequent cause of inferior ureter deviation but in only one case did they infiltrate into the wall and they were more constant on the right side. These cases are compared with other patients suffering from different pathologies, some of which are also neoplastic but in which no displacement or ectasia appeared even when the retroperitoneum was affected, and with another group of patients in whom there was found to be ureteral displacement or ectasia without any retro- or intraperitoneal pathology.

Ten cases are presented of ectopic openings of the ureter. The authors stress the embryological considerations concerning this congenital malformation as well as the clinical and radiological characteristics and the means of diagnosis applied in our patients.
