Long-term effects of episiotomy on urinary incontinence and pelvic organ prolapse: a systematic review

Purpose: To focus attention on the long-term effects of episiotomy on urinary incontinence and pelvic organ prolapse. Methods: A systematic review was conducted including only studies with mean follow-up ≥ 5 years. We searched using combinations of the following keywords and text words: “episiotomy”, “perineal laceration”, “perineal tear”, “perineal damage” and “long term”, “long term outcomes”, “prolapse”, “pelvic organ prolapse”, “pelvic floor”, “pelvic floor dysfunction”, “urinary incontinence”, “hysterocele”, “cystocele” and “rectocele”. Results: The electronic database search provided a total of 6154 results. After exclusions, 24 studies were included yielding the following results: (1) episiotomy might be detrimental with respect to urinary incontinence symptoms; (2) the relationship between episiotomy and anti-incontinence surgery is not clear; (3) episiotomy does not seem to negatively influence genital prolapse development and might even be protective with respect to prolapse severity and prevalence; (4) episiotomy does not seem to affect genital prolapse surgery rate. Conclusions: We did not find evidence for a long-term beneficial effect of episiotomy in the prevention of urinary incontinence symptoms and anti-incontinence surgery. Episiotomy does not seem to negatively influence genital prolapse development and might even be protective with respect to prolapse severity and prevalence without affecting surgery rates.
