Percutaneous transpouch management of a ureteral stone and ureteral-pouch stricture in a pelvic kidney.

Stones in pelvic kidney collecting systems have not been routinely managed percutaneously in most urologic practices. Especially challenging is the management of stones in a pelvic kidney collecting system positioned posteriorly to a urinary diversion. In the present case, a 32-year-old man with a pelvic kidney and continent urinary diversion presented with fever and hydronephrosis. Drainage of the kidney was obtained percutaneously by way of an anterior approach through-and-through the urinary diversion. The patient was found to have both a ureteral stone and a ureteral-pouch anastomotic stricture on subsequent imaging. We were able to successfully treat both these problems endoscopically through a solitary percutaneous access.
