直肠癌根治术后最常见的并发症之一就是排尿功能障碍。曾有人报导,所有直肠癌根治术患者都有急性尿潴留。膀胱机能失调是由于支配它的付交感神经障碍所引起,是因为会阴部创伤、膀胱炎症、下尿路损伤、骨盆内血肿、膀胱颈及其周围组织肿胀等因素所造成的。 One of the most common complications after radical resection of the rectum is micturition dysfunction. It has been reported that all patients with rectal cancer have acute urinary retention. Bladder dysfunction is caused by sympathetic disorders that dominate it because of perineal trauma, inflammation of the bladder, lower urinary tract injury, pelvic hematoma, swelling of the bladder neck and surrounding tissue, and other factors.
