Antegrade ureteral intussusception: A rare complication of percutaneous endopyelotomy

Abstract

Ureter intussusception is a rarely reported event and is usually secondary to a ureteral lesion. We report a case of a 15-year-old boy developing antegrade ureteral intussusception secondary to percutaneous endopyelotomy performed for pelvicaliceal junction obstruction. The most appropriate treatment is likely to be surgical excision coupled with pyeloplasty reconstruction or nephrectomy if renal function is beyond salvage. To our knowledge, this has never been reported, and we believe that awareness of this complication should be made known to urologists.
