A Proximal Straining Mesh Location Is Associated With De Novo Stress Urinary Incontinence After Transobturator Mesh Procedures

The purpose of this study was to explore the association between mesh location and de novo stress urinary incontinence (SUI) after transvaginal mesh procedures.

We retrospectively analyzed a database of women who had received transvaginal mesh procedures for stage III or greater cystocele according to the Pelvic Organ Prolapse Quantification system. Only data for women who neither reported SUI preoperatively nor had received concomitant anti-incontinence surgery were included for analyses. The mesh location was investigated by sonography via the percentage of the urethra covered by mesh, defined as the number calculated by dividing the portion of the urethral length covered by mesh (the distance from the bladder neck to the point of the urethra, which was indicated by an imaginary line at the level of the lower [caudal] mesh end and perpendicular to the urethra) by the total urethral length (the distance from the bladder neck to the external urethral meatus) in the sagittal plane. The resting, straining, coughing, and squeezing mesh locations of women who did (n = 29) and did not (n = 54) report SUI at the 12-month follow-up were compared.

At the 12-month follow-up, women who reported SUI had a significantly smaller straining percentage of the urethra covered by mesh (mean ± SD, 28.5% ± 9.6%) compared with continent women (35.2% ± 15.8%), indicating a more proximal straining mesh location.

Sonography is useful in investigating the location of the transvaginal mesh. De novo SUI after transvaginal mesh procedures is associated with a more proximal straining mesh location.
