title: Primary and repeat surgical treatment for female pelvic organ prolapse and incontinence in parous women in the UK: a register linkage study.
abstract: Objectives To determine the lifetime risk of undergoing pelvic floor surgery in a cohort of UK parous women and the re-operation rates for pelvic floor surgery, time intervals for repeat surgery and independent risk factors for undergoing primary and repeat pelvic floor surgery.  Study design A register linkage study.  Main outcome measures The primary outcome was lifetime risk of parous women in the UK undergoing pelvic floor surgery for pelvic organ prolapse (POP), urinary incontinence (UI), and rectal prolapse or faecal incontinence (RP-FI). Secondary outcomes were re-operation rates and time interval of repeat surgery for POP/UI, and independent risk factors for undergoing primary and repeat pelvic floor surgery.  Results 34 631 women identified from the Aberdeen Maternity and Neonatal Database were linked with the Scottish Morbidity Records databases of NHS Scotland to assess relevant outcomes. The lifetime risk for women by age 80 years of undergoing any form of pelvic floor surgery was 12.2%. 2130 (6.2%) women had at least one pelvic floor surgery, of whom 407 (19%) had repeat operations. The median time intervals (IQR) between index and repeat UI and POP surgery were 2.80 (0.94-8.07) years and 3 (1.00-8.25) years, respectively. There is a reduced lifetime risk of pelvic floor surgery in women who had all deliveries by caesarean section (p<0.001) and those aged <20 years at first delivery (p=0.021). Women who sustained at least one perineal laceration (in the absence of a classified perineal tear) during delivery or who had at least one instrumental delivery with forceps use were at increased risk (p<0.001 and p=0.015, respectively).  Conclusions Our study shows that in the UK more than one in 10 parous women will require at least one surgical procedure for pelvic floor disorders over their lifetime. The study also identifies independent risk and protective factors for pelvic floor surgery in parous women.
