Combined radical prostatectomy and abdominoperineal resection for locally invasive rectal cancer.

Introduction: An infiltration of urological organs is found in 5-10% of patients with colorectal carcinoma. Total pelvic exenteration is the standard procedure for locally advanced rectal cancer. In selected patients with rectal cancer involving the prostate or seminal vesicles, the bladder can be preserved and en bloc radical prostatectomy with abdominoperineal rectal resection can be performed.
