Between August, 1986 and February, 1988, double J ureteral catheters were placed in 441 renal units of 419 patients (22 were bilateral) with complex renal stones prior to ESWL. Catheter placement was achieved in all but 3.8% of the cases using several techniques, mainly via the retrograde route. Placement of the double J catheter was indicated in almost 75% of cases with a large stone mass (staghorn or pseudo staghorn). ⋯ We believe that the double J catheter is useful in patients with complex renal stones. Placement of a double J catheter involves a simple maneuver with a low morbidity. It aids ESWL, reduces complications, and avoids more important endourologic maneuvers.

Review Case Reports
[Spontaneous subcapsular hematoma of the kidney associated with tubulopapillary neoplasm in a patient undergoing hemodialysis].
We report on a patient with chronic renal failure undergoing hemodialysis who presented with spontaneous renal subcapsular hematoma associated with a tubulo-papillary tumor. The literature relative to this condition is reviewed. Its incidence, predisposing factors, diagnostic methods and treatment are discussed.

We report an unusual case of acute ureteral obstruction caused by a shotgun pellet that penetrated the upper collecting system and posteriorly descended into the ureter. The clinical course of the patient is described. To our knowledge, a similar case has not been reported in the literature.

Case Reports
[Early calculogenesis caused by ureolytic infection of the double-J ureteral catheter].
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. ⋯ 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.
