The piriformis syndrome is a condition allegedly attributable to compression of the sciatic nerve by the piriformis muscle. Recently, magnetic resonance neurography and electrophysiologic study have helped to diagnose piriformis syndrome. High dose radiotherapy could induce acute and delayed muscle damage. We had experienced piriformis syndrome with fatty atrophy of piriformis muscle after radiotherapy for recurrent cervical cancer.

Ureterosciatic hernia is extremely rare. In ureteral herniation, ureter prolapses occur through either the greater or lesser sciatic foramen. Atrophy of the piriformis muscle, hip joint diseases, and defects in the parietal pelvic fascia are predisposing factors for the development of ureterosciatic hernia. Most symptomatic patients have been treated surgically, with conservative treatment reserved only for asymptomatic patients. To the best of our knowledge, long-term follow-up outcomes after ureterosciatic hernia management are sparse. In this paper, we report the case of a 68-year-old woman who presented with colicky left abdominal pain. After computed tomography (CT) scan and anterograde pyelography, she was diagnosed ureterosciatic hernia with obstructive uropathy. We performed ureteral balloon dilatation and double-J ureteral stent placement. After this minimally invasive procedure, CT scan demonstrated that the left ureter had returned to its normal anatomical position without looping into the sciatic foramen. The patient remained asymptomatic with no adverse events 7 years after the minimally invasive procedures. This brief report describes ureterosciatic hernia successfully managed with minimally invasive procedures with long-term follow-up outcomes.
