A simple, self-retaining intraurethral catheter for treatment of prostatic obstruction

An intraurethral catheter was successfully used in 38 of 47 (80.9%) patients with benign prostatic hyperplasia who were awaiting surgery or in whom surgery constituted a high risk. All patients had indwelling catheters due to urinary retention. The device was inserted via a cystoscope or a specially designed insertion set. The insertion was performed in the outpatient clinic under local anesthesia and did not require more time than the cystoscopy itself. The intraurethral catheter remained in place for up to 41 weeks. None of the patients developed clinically evident urinary tract infections. Voiding and continence were satisfactory in all, although 8 (21%) suffered some degree of frequency of micturition. There are apparently no limitations in the use of the intraurethral catheter. Compared to other techniques and devices for treatment of urinary retention, the intraurethral catheter appears to be more physiological, easier to insert and remove, and more economical. We recommend intraurethral catheter insertion for up to 6 months in patients who are awaiting surgery and as an alternative for high-risk patients. In the latter, the intraurethral catheter should be changed after 6 months.
