[URETEROSCIATIC HERNIA TREATED BY URETERAL STENT PLACEMENT].

Ureterosciatic hernia is an uncommon condition that can cause ureteral obstruction. Here, we report a case of ureterosciatic hernia successfully treated by ureteral stent placement. A 95-year old woman presented to our emergency department with high fever. An abdominal CT scan revealed mild left hydronephrosis and urinalysis identified pyuria. The patient was subsequently admitted to hospital with a diagnosis of complicated pyelonephritis. No recovery was evident after antimicrobial treatment, a repeat CT scan revealed a ureterosciatic hernia. We indwelled a left ureteral stent and repaired the hernia. We did not opt for a surgical approach because of the patient's age and presence of dementia. The stent was removed after 2 months, but the patient was re-admitted 4 months later because of pyelonephritis. Here, we indwelled a left ureteral stent, and the patient underwent regular ureteral stent exchange. Placement of a ureteral stent for ureterosciatic hernia is an effective treatment for elderly patients and those who are poor surgical candidates.
