OBJECTIVE: To compare two commonly used modifications to the standard Q-tip test for urethral hypermobility: catheter alone and catheter with Q-tip. METHODS: All women referred for the evaluation of urinary incontinence or pelvic organ prolapse were included in the study. A postvoid residual urine was collected on each patient and the angle of the urethra with the horizontal plane was measured at rest and with Valsalva with the Q-tip, catheter alone, and catheter with Q-tip. The test was considered positive if the angle of excursion was 30 degrees or more. RESULTS: In this group of 100 consecutive women with urinary incontinence or pelvic organ prolapse, the mean change in the angle was significantly different from the standard Q-tip test (51 degrees) when catheter alone (35 degrees, P<.001) or catheter with Q-tip modifications were used (44 degrees, P<.001). This difference was due to a significant reduction in the resting and Valsalva maneuver angles with the catheter alone, and a significant decrease only in the Valsalva maneuver angle with the catheter with Q-tip method (P<.001). The percentage of positive tests for the standard Q-tip test (92%) was significantly different from the catheter only method (63%, P<.001), and from the catheter with Q-tip technique (83%, P=.021). The "best match" values of 10 degrees for the catheter alone, and 15 degrees for the catheter with Q-tip methods produce the best equivalent results at this time. CONCLUSION: The use of a catheter, instead of a Q-tip, in the evaluation of urethral hypermobility resulted in reduced angles of excursion from resting to Valsalva maneuver.
