A suprapubic drainage catheter (10) for draining the bladder and maintaining the patency of the urethra of a patient following a radical prostatectomy. The catheter includes an elongated member (11) having a drainage passage(12) extending longitudinally therein and a plurality of drainage ports (21) in a drainage portion (14) thereof for providing external access for the drainage passage in the bladder of the patient. First and second retention balloons (17, 18) are connected with the elongated member and positioned distally and proximally of the drainage ports, respectively. The elongated member also includes first and second inflation passages (26, 27) for individual and independent inflation and deflation of the retention balloons. One-way connector valves (32, 33) are positioned at the proximal end of the catheter for controlling inflation and deflation of the balloons via the inflation passages. The elongated member also includes a proximal portion (15) that extends through the percutaneous access site (30) for connection of a urine collection bag (not shown) to the drainage passage and further includes a distal portion (13) that extends from the bladder into the urethra through the anastomotic site (20) to maintain the patency of the urethra thereat.
