Multicenter Study on Suprapubic Catheterization Versus Transurethral Catheterization in Laparoscopic Surgery for Rectal Cancer

Multicenter Study on Comparing Suprapubic Catheterization Versus Traditional Transurethral Catheterization in Laparoscopic Surgery for Rectal Cancer

Compared with traditional open proctectomy, laparoscopic surgery is associated with less pain, earlier recovery, and better cosmetic outcome, and its long-term oncologic outcomes have been demonstrated. However, the rate of urinary dysfunction after rectal cancer surgery was about 19-38% because of mesorectal excision. The type of drainage is unclear. Some studies show that the rates of urinary tract infection, second catheterization, and urinary symptom are lower with suprapubic catheterization (SPC) than with transurethral catheterization (TUC). Moreover，SPC allows for testing the bladder voiding without drainage removal. Furthermore，SPC using central venous catheter(CVC) is less invasive.

Currently, there is lack of randomized controlled trial(RCT) to compare SPC with TUC. Therefore, investigators perform this prospective randomized trial to compare SPC using CVC with TUC in laparoscopic surgery for rectal cancer.
