Does Pharmacological Treatment Reduce the Incidence of Lower Urinary Tract Symptoms (LUTS)‎ after Transobturator Sling?

الملخص EN

Aim.

Lower urinary tract symptoms (LUTS) frequently affect patients immediately after midurethral sling (MUS) placement.

The objective of the study was to assess if solifenacin or mirabegron decreases incidence of LUTS in women who underwent transobturator MUS.

Methods.

A prospective randomized trial was conducted on patients undergoing ambulatory transobturator midurethral sling due to stress urinary incontinence (SUI).

All participants were questioned before and after surgery for occurrence of bothersome LUTS.

A total of 328 patients who underwent transobturator MUS were randomly assigned to one of three groups: prophylaxis with 10 mg of solifenacin, prophylaxis with 50 mg of mirabegron, or without any additional treatment.

LUTS evolution and efficacy of solifenacin and mirabegron were analyzed based on results of assessments made during follow-up visits at 1 and 6 weeks after surgery.

Comparison of the prevalence of LUTS was done using chi2 test.

Results.

Prevalence of urgency and frequency episodes increased notably 1 week after sling placement and then came down to baseline levels.

Solifenacin and mirabegron significantly reduced the incidence of urgency after 1 week, but after 6 weeks the beneficial effect was observed only in case of solifenacin.

Treatment with mirabegron reduced the percentage of patients suffering from frequency after 6 weeks.

Although prevalence of nocturia did not raise after sling placement, both treatments significantly reduced the incidence of this complaint after 6 weeks.

Pharmacological treatment did not modulate the course of hesitancy and terminal dribbling.

Conclusions.

Treatment with solifenacin or mirabegron may significantly reduce the incidence of undesired LUTS after MUS.
