OBJECTIVE: To investigate the effect of vaginal prolapse and bladder fullness on Q-tip test assessment of urethral mobility.
METHODS: Twenty-six women with genital prolapse to or beyond the hymen and undergoing urodynamics for urogynecologic dysfunction were assessed by the Q-tip test. Measurements were obtained with the bladder empty, with and without the prolapse reduced by the posterior blade of a Graves speculum. Angles were repeated at bladder capacity. Measured Q-tip angles were compared using the Wilcoxon signed rank test.
RESULTS: Q-tip angles were significantly altered by vaginal prolapse and bladder fullness. With an empty bladder, the median Q-tip angle measured with the prolapse reduced was significantly less than that measured without reduction (53 degrees, interquartile range 25-65, versus 68 degrees, interquartile range 45-75; P <.001). With a full bladder, similar but lesser results were obtained (33 degrees, interquartile range 15-55 [reduced] versus 48 degrees, interquartile range 31-60 [unreduced]; P <.001). The median Q-tip angle with an empty bladder was greater than that with a full bladder. With the prolapse reduced, the Q-tip angle was 53 degrees (interquartile range 25-65) with an empty bladder versus 33 degrees (interquartile range 15-55) with a full bladder (P <.001). Without the prolapse reduced, the median Q-tip angle was 68 degrees (interquartile range 45-75) with an empty bladder and 48 degrees (interquartile range 31-60) with a full bladder (P <.001). CONCLUSION? Measurement of urethral mobility by the Q-tip test is significantly affected by genital prolapse. Q-tip angles are less with the reduction of vaginal prolapse and with the bladder full. Standardization of measurement technique is necessary for the development of clinical management recommendations.
