Introduction: Iatrogenic 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 presentation: An 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.
Conclusion: This study reported a case of one-stage laparoscopic drainage and ureterocystoneostomy for iatrogenic ureteral injury with infected urinoma.
