Vaginal, sexual and urinary symptoms following hysterectomy: a multi-centre randomized controlled trial

BACKGROUND: Hysterectomy is the most common major gynaecological procedure. The aim of this study was to study vaginal, sexual and urinary symptoms following total abdominal hysterectomy (TAH), non-descent vaginal hysterectomy (NDVH) and total laparoscopic hysterectomy (TLH) in a low resource setting. METHODS: A multi-centre randomized controlled trial (RCT) was conducted in two public sector hospitals in Sri Lanka. Participants were patients requiring hysterectomy for non-malignant uterine causes. Exclusion criteria were uterus> 14 weeks, previous pelvic surgery, medical illnesses which contraindicated laparoscopic surgery, and those requiring incontinence surgery or pelvic floor surgery. Vaginal, sexual function and urinary symptoms were assessed by the validated translations of ICIQ-VS and ICIQ-FLUTS questionnaires. Post-operative improvement (pre-operative – post-operative) was assessed. RESULTS: There was an improvement (median (IQ1-IQ3) in vaginal symptoms [TAH 6(2–8) vs 4(0–8), p < 0.001; NDVH 6(4–8.5) vs 5(0–8), p < 0.001; TLH 4(2–10.5) vs 4(0–10), p < 0.001], urinary flow symptoms [TAH 2(1–4) vs 1 (0–3), p < 0.001; NDVH 3 (2–5) vs 2 (0.5–4), p < 0.001; TLH 1(1–4) vs 1(0–3), p < 0.05], urinary voiding symptoms [TAH 0(0–0) vs 0(0–0), p = 0.20; NDVH 0(0–1) vs 0(0–0.8), p < 0.05; TLH 0(0–0) vs 0(0–0), p < 0.05] and urinary incontinence symptoms [TAH 0(0–2) vs 0(0–2), p = 0.06; NDVH 0(0–3) vs 0(0–3), p < 0.001; TLH 0(0–3) vs 0(0–2), p < 0.05] at 1-year (TAH n = 47, NDVH n = 45, TLH n = 47). There was an improvement in sexual symptoms only in the TLH group [TAH 0(0–11.5) vs 0(0–14), p = 0.08); NDVH 0(0–0) vs 0(0–0), p = 0.46; TLH 0(0–0) vs 0(0–4), p < 0.05]. There was no significant difference among the three different routes in terms of vaginal symptoms score [TAH 2 (0–2), NDVH 0 (0–2), TLH 0 (0–2), p = 0.33], sexual symptoms [TAH 0 (0–0), NDVH 0 (0–0), TLH 0 (0–0), p = 0.52], urinary flow symptoms [TAH 0 (0–1), NDVH 0 (0–1), TLH 0 (0–2), p = 0.56], urinary voiding symptoms [TAH 0 (0–0), NDVH 0 (0–0), TLH 0 (0–0), p = 0.64] and urinary incontinence symptoms [TAH 0 (0–0), NDVH 0 (0–1), TLH 0 (0–1), p = 0.35] at 1-year. CONCLUSIONS: There was a post-operative improvement in vaginal symptoms and urinary symptoms in all three groups. There was no significant difference in pelvic organ symptoms between the three routes; TAH, NDVH and TLH.
