An indwelling urethral catheter arrangement for the prevention of ascending bacterial infection which is of such a design that, on the one hand the bacteria are flushed downwardly by urine permitted to flow along the inside of the urethral wall and, on the other hand, the entire urinary stream is conducted, with the aid of a condom-like sheath fittable over the tip of the penis, to the outside of the catheter arrangement; in this fashion soiling of the patient\s clothing will be avoided regardless of the flushing provision.

Indwelling urethral catheter arrangement for the prevention of ascending bacterial infection, comprising a catheter shaft having an upper section with a diameter sufficiently large to substantially prevent passage of urine externally thereof, and a lower section at least a part of which is of reduced diameter, said catheter shaft having lateral outlet opening means near the upper end of said part, lateral inlet opening means at a lower point of said part and lumen stopper means intermediate said outlet and inlet opening means so that the urinary stream is deflected for relatively free flow over the distance defined by said opening means to the generally annular space between the urethral wall and the outside of said catheter shaft, and a condom-like sheath in the region of said lower end, said sheath at its bottom having an aperture surrounding the lower section of said catheter shaft in sealing relationship, and at its top being fittable over the penis, so that, on the one hand, the bacteria are flushed downwardly by the urinary stream and , on the other hand, the entire urinary stream is conducted in a leakproof manner to the outside of said catheter arrangement.
