Recurrent stress urinary incontinence surgery in the United Kingdom: an analysis of the British Society of Urogynaecology database (2007-2015).

INTRODUCTION AND HYPOTHESIS

There is a lack of robust evidence guiding treatment options for recurrent stress urinary incontinence (SUI) and limited comparative outcome data. The aim of this study was to examine the pattern of surgery for recurrent SUI performed by gynaecologists in the UK and compare subjective success rates.

METHODS

Retrospective review of the British Society of Urogynaecologists database for patients having repeat incontinence procedures (2007-2015) including the number of each procedure and outcome recorded by the International Consultation on Incontinence Urinary Incontinence Short Form (ICIQ-UI-SF) questionnaire. Procedures were compared by year and outcomes by operation. Categorical comparisons were performed using Chi-squared test and numerical comparisons using appropriate non-parametric tests.

RESULTS

A total of 2,938 records were obtained (269 were excluded) and 2,164 women (88.8%) had undergone one previous procedure, most commonly retropubic midurethral sling (MUS; 28.6%). Pelvic floor exercises were offered to 76.2% women. Urodynamic investigation was carried out in 96.2% women: 76.5% had urodynamic stress incontinence. Repeat MUS was the most common procedure (77.3%), followed by bladder neck injections (BNI; 10.2%). Follow-up details were available for 66.1%. Outcome data were poorly reported. Median ICIQ-UI-SF score fell from 16 (0-21) to 0 (0-21) (p < 0.001), 81.6% felt "much better" or "very much better" on Patient Global Impression of Improvement (PGI-I), and 89.3% "cured" or "improved". MUS, colposuspension and fascial sling showed the best results with regard to the PGI-I score and "change in SUI" (p < 0.001).

CONCLUSION

MUS and BNI were the most common repeat continence procedures. Follow-up data suggest that MUS, colposuspension and fascial sling are most effective.
