A case of one‐stage laparoscopic drainage and ureterocystoneostomy for iatrogenic ureteral injury associated with infected urinoma

Abstract

IntroductionIatrogenic ureteral injury is a rare but often encountered complication of abdominal and gynecological surgery. This is a case of iatrogenic ureteral injury with infected urinoma treated with one‐stage laparoscopic drainage and ureterocystoneostomy.Case presentationAn 80‐year‐old man with rectal cancer had robot‐assisted low anterior rectum resection and left lateral lymph node dissection after colostomy and preoperative chemoradiotherapy. On the 14th postoperative day, he had a fever, and a noncontrast‐enhanced computed tomography scan revealed a low‐density polycystic area in the left pelvic cavity. Retrograde pyelography revealed contrast medium leaking from the left lower ureter, preventing ureteral stent placement. We identified it as a delayed ureteral injury with infected urinoma and performed laparoscopic one‐stage drainage and ureterocystoneostomy.ConclusionThis study reported a case of one‐stage laparoscopic drainage and ureterocystoneostomy for iatrogenic ureteral injury with infected urinoma.
