Ureterosciatic hernia with gluteal abscess: A case report

A woman in her 90's developed pain in the left buttock, along with a left buttock mass. Contrast-enhanced computed tomography revealed a mass in the left gluteus muscle, ureteral dilation, and pelvic ureteral disconnection. Retrograde urography revealed bending of the left ureter at the sciatic foramen. The patient was diagnosed with a ureterosciatic hernia and gluteal abscess and treated with ureteral stent placement and antibiotics. The patient experienced no recurrence during the follow-up period. The gluteal abscess was probably caused by urinary leakage due to ureteral obstruction, because the abscess and urine culture results were consistent.
