[A Case of Ureteral Sciatic Hernia Improved by Indwelling a Ureteral Stent].

A 75-year-old woman visited our hospital with left lumber pain and fever. Symptoms, and computed tomography imaging revealed left pyelonephritis. Then she was admitted to our hospital for treatment. She improved with tazobactam and piperacillin PIPC infusion immediately and was discharged from the hospital. After that she visited our hospital twice with the same symptoms and was given hospital treatment. A second retrograde pyelography (RP) was performed urgently, and the diagnosis was left ureteral sciatic hernia. Then we placed a left ureteral stent. Three months later, we confirmed that the hydronephrosis was improved and removed the stent. Six months after stent removal, recurrence has not been observed.
