A 70-year-old man underwent laparoscopic low anterior resection for a rectal adenocarcinoma after neoadjuvant chemoradiotherapy. Postoperatively, the patient had high drain volume output, with 800 mL of clear serous fluid being drained on the second postoperative day. Drain creatinine returned as 300 mmol/L, with a corresponding serum creatinine of 100 mmol/L. CT scan of the abdomen and pelvis confirmed a left ureteric injury with an associated urinoma. After urology consultation, the patient underwent a left ureteric reimplantation emergently.
