Bladder pain syndrome and sexual function: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Bladder pain syndrome (BPS)/interstitial cystitis can adversely affect physical, mental, and sexual health. The aim of the systematic review is to compare sexual function between patients with BPS and healthy controls and to examine whether or not treatment of BPS improves sexual function.

METHODS

A literature search was conducted on Embase, Medline, and other databases. Studies comparing sexual function in BPS patients with healthy controls and before/after treatment were included. Where appropriate, data were pooled in a meta-analysis, using a random effects model and the standardised mean difference (SMD) was used for comparison.

RESULTS

Out of 384 studies initially identified, 26 studies met the inclusion criteria for the systematic review and 11 for the meta-analysis. Six studies compared sexual function in BPS cases with healthy controls. All studies found that the Female Sexual Function Index (FSFI) was worse in BPS cases than in controls. Pooled data from 5 studies showed that the SMD was -1.02 (CI -1.64, -0.4) in total FSFI scores between the cases and controls, p=0.001. Further analysis showed better sexual function in all FSFI subdomains in healthy controls. Five studies compared sexual function in BPS patients before treatment with after treatment. Pooled data from 3 studies showed an overall improvement in total FSFI score after intravesical treatment: SMD=0.69 (CI 0.23, 1.14), p=0.003. Further analysis showed improvement in all subdomains.

CONCLUSION

Our review suggests that sexual function might be worse in BPS patients than in the general population, but it seems to improve with intravesical BPS treatment.
