[A Case of Calyceal Diverticula with Stones Treated by Ureteroscopic Management].

Abstract

Most patients with calyceal diverticula stones are asymptomatic, but some patients experience fever and low back pain. Here we report a case of calyceal diverticula stones treated by ureteroscopic management. A 41-year-old woman with backache visited a local doctor. She was diagnosed with a urinary tract infection, and prescribed an antibiotic. Her symptoms began to improve, but the ultrasonography showed she had a left renal cystic lesion, so she visited our hospital. Abdominal contrast-enhanced computed tomography (CT) showing in-flow of a contrast agent into the left renal calyceal diverticula located stones in the upper pole. We performed ureteroscopic management of the calyceal diverticula stones in two stages. First, we expanded the neck of the calyceal diverticula by indwelling the ureteral stent at the calyceal diverticula. Then, using a ureteral dilator, we expanded the neck of the calyceal diverticula further and removed the stones in the calyceal diverticula. Treatment with ureteroscopic management was possible due to the location of the calyceal diverticula stones and the success rate was increased by performing the treatment in two stages.
