OBJECTIVE: The aim of the present study was to verify the usefulness of Point Aa as a substitute marker of the Q-tip angle and urethral mobility before and after midurethral sling operation for the treatment of stress urinary incontinence (SUI) in women.
METHODS: In this study, 118 women presenting with SUI who underwent the tension-free vaginal tape obturator (TVTO) procedure were prospectively examined and followed-up for ≥6 months after operation. Spearman's correlation coefficient was used to assess the degree of correlation between Point Aa of the Pelvic Organ Prolapse Quantification system and Q-tip angles before and after midurethral sling surgery.
RESULTS: There were significant postoperative changes in Point Aa (from -0.4 ± 1.9 to -2.7 ± 0.6; P = .001) and Q-tip angle (from 58.7 ± 19.4 to 15.4 ± 17.5 degrees; P =.001) compared with preoperative values. A fair correlation between Point Aa position and straining Q-tip angle was found before (r = 0.45, P = .05) and after (r = 0.49, P = .04) the procedure, with no significant difference in values before and after the procedure (P = .62).
CONCLUSIONS: The results of the present study show fair correlation between the Point Aa position and straining Q-tip angle before and after midurethral sling surgery. Point Aa could be used as an indicator of urethral mobility after the TVTO procedure in women with SUI.
