[Urological problems in the treatment of recurrent colorectal carcinoma]

The infiltration of the ureters, bladder or urethra by recurrent colorectal carcinoma raises both urodynamic and surgical problems. These include the question of whether reconstruction or urinary diversion is indicated. The present paper describes the surgical procedures carried out in 19 patients with tumour extention of recurrent colorectal carcinoma to the urinary tract. In the majority of cases the treatment of choice can be decided only intraoperatively. It is important to choose the procedure which guarantees both surgical radicality and minimal discomfort to the patient.
