[Control of retrograde urethrocystitis by converted Y-type urethral catheter].

A converted Y-type urethral catheter was used to curb retrograde urethrocystitis due to indwelling urethral catheter. Satisfactory results were obtained in 30 cases. Injection of 0.5% bromo-geramine (10 ml) into the bladder through the bypass tube killed effectively the bacteria in the indwelling catheter. The device had the functions of urine deposit, urine conduction, bladder and urethral washing as well as urine sample collection. The connection between indwelling urethral catheter and the conducting tube was not dismantled during the procedure. So it reduced the chance of extraneous contamination.
