Pelvic floor ultrasound evaluation in the diagnosis of exposure of synthetic implanted materials in the lower urinary tract.

OBJECTIVE

To evaluate the diagnostic performance of pelvic floor ultrasound (PFUS) to recognize prosthetics exposure in the bladder and/or urethra in women with lower urinary tract symptoms (LUTS).

METHODS

A cross-sectional study evaluating patients with LUTS after mesh/sling surgery. PFUS was performed with both transvaginal (TVUS) and translabial (TLUS) approaches. A distance of 1 mm or less from the bladder and/or urethra was considered highly suspect for mesh exposure. After PFUS, patients underwent diagnostic urethrocystoscopy.

RESULTS

A total of 100 consecutive women were analyzed. According to urethrocystoscopy, the rate of tape exposure in the lower urinary tract was 3%. PFUS showed 100% sensitivity and 98%-100% specificity in detecting lower urinary tract mesh exposure. The negative predictive value was 100% and the positive predictive value ranged from 33% to 50% for urethral and 100% for bladder exposure.

CONCLUSIONS

PFUS represents an effective and reliable non-invasive screening test to exclude prosthetics exposure in the bladder and/or urethra in women with LUTS.
