Abstract:
Background Vesicourethral function returns after radical rectal surgery during the first year but rarely progresses after 1 year. We examined the urodynamics of patients whose voiding dysfunction remained after 1 year, and treated several with a modified sphincterotomy procedure similar to radical transurethral resection of the prostate. Methods We analyzed the urodynamic features of vesicourethral dysfunction in 16 male patients with persistent voiding dysfunction for more than 1 year following radical surgery for rectal carcinoma. Seven patients elected to undergo radical transurethral resection of prostate (radical TUR‐P) for the relief of their persistent voiding dysfunction. Results The mean bladder volume at the first desire to void was 210 mL, the mean maximal bladder capacity was 343 mL, and the mean vesical compliance (C ves ) was 27.1 mL/cm H 2 O. All patients demonstrated either vesical denervation supersensitivity (V ds ) or uninhibited contraction. The mean maximal urethral closure pressure was 43.9 cm H 2 O, and urethral denervation supersensitivity was found in 77.8% (7/9), and sphincter dyssynergia in 66.7% (6/9) of patients. After radical TUR‐P, 5 patients became free from the use of self‐catheterization, 1 patient had a reduced residual urine rate, and 1 patient was unchanged, but no patient noted a change in urinary control. Conclusion Urethral dysfunction after radical rectal surgery was caused by failure of the bladder to empty along with an underactive detrusor. Radical TUR‐P was effective in restoring voiding function in a selected group of these patients.
