text: does prostate surgery have to result in incontenance? i have no discomfort. i do have large bladder and prostate gland as with all surgery there are inherant risks but prostate surgery does not lead to urinary incontinence all of the time. it all depends on the procedure as there are different forms of prostate surgery. the greatest risk of urinary incontince would follow a prostatectomy- which is the complete removal of the prostate gland. it is not the removal of the prostate itself which causes the incontince but the possible destruction of detrusor muscles at the neck of the bladder during removal of the prostate. this leads to having no control of the sphincter muscles in the bladder and thus incontinence. other forms of prostate surgery include trans urethral resection of prostate- a key hole operation to 'shave' away excess prostate growth that occurs in cancer of the prostate or benign prostatic hyperplasia.urinary incontinence is far less common in this treatment.
