Using stainless steel chopstick for self-performing urethral sounding in preventing recurrence of anterior urethral stricture.

Male urethral stricture is prone to recurrence, ranging from 40% to 80% according to the length of stricture no matter what treatment is introduced. Therefore, it has long been a common challenge for urologists to handle the problem. Sounding or self-dilation has proved to be effective in reducing the recurrence rate significantly. However, a standard equipment set of urethral bougie is too expensive for a patient's own use. On the other hand, the performance of regular outpatient sounding is time-consuming and costly. We present an easy way to perform urethral self-dilation using a stainless steel chopstick, which has proved to be cost effective and satisfactory for patients. From February 2001 to February 2003, 6 patients, with a mean age of 64.6 years (range 47-79), were introduced to this maneuver after a urethrotomy and were taught how to perform self-sounding with a stainless steel chopstick (18 Fr equivalent). The distance of advancement was determined individually by calibrating the location of the stricture. The long-term result of this maneuver was later checked with a telephone questionnaire about urination status in April 2005. The urethral strictures were located at penile in 3 patients, bulbar in 1, and navicular fossa with meatus in 2. The mean period for performing self-dilation was 15.3 weeks (range, 2-52). The mean follow-up period was 41.5 months (range, 26-55). No recurrence of stricture was found.
