OBJECTIVE:

To determine the changes in point Aa of the POP-Q system and in the Q-tip test for urethral hypermobility as well as in the urodynamic parameters found before and 1 year after mediurethral sling placement.

MATERIALS AND METHODS:

Retrospective study carried out in patients who were placed with a mediourethral tape by transobturator and retropubic access, by diagnosis of stress urinary incontinence, mixed urinary incontinence, dual incontinence or with risk index of de novo urinary incontinence after surgery. Prolapse (R-CALC) greater than 30%.

RESULTS:

200 patients of 51.59 ± 10.13 years of average age were studied. According to the degree of pelvic organ prolapse, stage II had a frequency of 57.5% (n = 115), grade III with 21.5% (n = 43). In the physical examination findings, prior to surgery, it was found that 69% (n = 138) of the patients had a Q tip test with urethral hypermobility (more than 30°). When comparing the percentage of patients with urethral hypermobility after 1 year of surgery, a decrease was observed in patients with hypermobility (p = 0.0001). The quantification of point Aa on the scale of the POP-Q system was found during the preoperative examination at 0.1 ± 1.17 cm with respect to the hymen and one year after the surgical procedure at -1.54 ± 1.18 cm, with p = 0.0001.

CONCLUSION:

The significant decrease in point Aa in the reassessment of POP-Q from stage II to I after the placement of a mediourethral tape in all patients was demonstrated, in addition to the decrease in the angle of urethral mobility. No significant changes were observed in the urodynamic parameters evaluated.
