There are two types of cystectomy: partial cystectomy and total cystectomy: first, partial cystectomy, this type of surgery to remove limited lesions in the bladder, the normal tissue will be sutured up again, the normal physiological place to store urine and urination is not affected, but after the surgery may occur frequent urination and each time the volume of urine is reduced, does not affect life; second, total cystectomy, if the lesions in the bladder are extensive and the bladder can not be preserved, then the total cystectomy, at which time a section of intestinal tube is needed to artificially construct a new bladder by rolling the intestinal tube into a tubular or bulbous shape and completing the new bladder through a body stoma or in situ urethral anastomosis. The new bladder at this point has no bladder holding sensation and may present with short-term postoperative incontinence, or weak bladder contraction resulting in the need for assisted manual pressure for urination, or indwelling tube for urination.
