A prostatic obstruction relief catheter for insertion in the urethra of a male patient comprises an elongated, flexible, tubular, plastic catheter body 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 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.

L'invention porte sur une sonde de dégagement d'une obstruction prostatique qui s'insère dans l'urètre des hommes malades. La sonde comporte un corps de plastique allongé, souple et tubulaire, dont la paroi est généralement cylindrique. Elle est divisée, sur sa longueur, en une zone de rétention urinaire, une zone d'écartement de la prostate, une zone conçue pour fonctionner avec le sphincter urinaire et une zone se prolongeant au moins partiellement dans le pénis pendulaire. Le corps de cathéter tubulaire comprend une série de trous percés radialement dans la paroi, trous qui communiquent librement avec une lumière. Ainsi, l'urine recueillie dans la vessie peut éviter la prostate hypertrophique du malade tout en étant contrôlée par le sphincter urinaire de ce dernier. Le malade ne souffre donc pas d'incontinence.
