A unique case of -related ureteral stricture: Diagnosis and surgical reconstruction.

Background: Chronic infection with can lead to pathology of the upper and lower urinary tracts. While well known as a cause of squamous cell carcinoma of the bladder, relatively little research exists on ureteral involvement. Here, we present a unique case of bilateral ureteral obstruction from schistosomiasis with concomitant ureteral stone disease.

Case Presentation: A 43-year-old male Somalian immigrant was diagnosed with a right proximal ureteral stone and bilateral multifocal ureteral narrowing causing obstruction with preserved renal function. He underwent a staged repair with right robotic pyelolithotomy and non-transecting ureteroureterostomy, followed by left robotic ureteroureterostomy with stricture excision. Pathology revealed ova.

Conclusion: Ureteral stricture from schistosomiasis represents a rare diagnosis for urologists in non-endemic countries. Bilateral ureteral narrowing and concomitant ureteral stone burden presented both diagnostic and reconstructive challenges, requiring a staged repair. Minimally invasive reconstruction was achieved using robotic assistance with good functional outcome.
