1. In a uninary catheter arrangement for irrigating the bladder in post-operative prostate or bladder surgery the combination comprising, a valve body having a circular bore and a valve core rotatably retained in said bore, said body having four generally perpendicularly related ports therein communicating with said bore, said valve core having a first peripheral portion in sealed relation with said bore and having a circumferential extent substantially only sufficiently large to block any two circumferentially adjacent ports when rotated to any one of four positions and sufficiently small to block only the intermediate one of three circumferentially successively positioned ports in an intermediate position thereof without blocking the other two of said three successively positioned ports, said vlave core having a second peripheral portion in sealed relation with said bore and positioned diametrically opposite the first portion, said second portion having a circumferential extent substantially only sufficient to completely block any one of said ports without blocking any of the other three ports, said two portions cooperating to define in said valve core a diametrically extending passageway and two additional passageways on the same side of the first-mentioned passageway whose axes are inclined to the axis of the first passageway at an angle of about 45* a catheter connected to a first of said ports and adapted to be inserted into the urinary tract of a patient, a supply of irrigating fluid connected to a second port circumferentially adjacent the first port, a urinary drainage bag connected to the third port, said third port being generally diametrically opposite the second pOrt, and an expandable-collapsible receptacle connected to a fourth port diametrically opposite the first port, whereby to enable rotation of the valve core in the following sequence to irrigate the bladder:

  • first rotate the valve core to establish communication between the second and fourth ports to enable a quantity of irrigating fluid to be drawn into the receptacle;

    then rotate the valve core to interconnect the first and fourth ports to successively discharge the irrigating fluid into the urinary tract and withdraw the same from the urinary tract back into the receptacle;

    then rotate the valve core to interconnect the third and fourth ports to discharge from the receptacle the irrigated fluid and the matter withdrawn therewith from the urinary tract and into the urinary bag;

    finally rotate the valve core to interconnect the first and third ports to permit conventional drainage from the urinary tract into the urinary drainage bag.
