Spontaneous rupture of the renal pelvis presenting as an urinoma in locally advanced rectal cancer

摘要

A 29-year-old gentleman underwent a transverse colostomy for intestinal obstruction caused by advanced rectal carcinoma.On the 5th postoperative day,the patient developed a painful swelling on the right side of the abdomen.The contrast enhanced computed tomography of the abdomen revealed a right sided hydronephrosis,a large rent in the renal pelvis,and a large retroperitoneal fluid collection on the right side.Percutaneous nephrostomy and pigtail catheter drainage of the urinoma led to resolution of abdominal swelling.Development of a urinoma as a consequence of rectal carcinoma is highly unusual.Prompt imaging for confirmation of diagnosis,decompression of the renal pelvicalyceal system,and drainage of the urinoma limits morbidity.
