A prostatic obstruction relief catheter (10) for insertion in the urethra of a male patient comprises an elongated, flexible, tubular, plastic catheter body (12) having a generally cylindrical wall where along its length it is partitioned into a bladder retention zone, a prostate gland spanning zone, a zone designed to cooperate with the urinary sphincter and a fourth zone extending at least partially through the pendulous penis. The tubular catheter body has a plurality of radially extending bores (28) through its wall and in fluid communication with a lumen, whereby urine collected in the bladder may readily bypass a patient's enlarged prostate gland while being controlled by his urinary sphincter to thereby maintain continence. <IMAGE> |
