Purpose: Information about the perioperative incontinence following hysterectomy is limited. To advance the postoperative rehabilitation further we need more information about qualitative changes in incontinence, fatigue and physical function of patients undergoing hysterectomy.
Methods: 108 patients undergoing planned hysterectomy were compared pre- and postoperatively. In a sub-study of the prospective follow-up study the changes in incontinence, postoperative fatigue, quality of life, physical function, and body composition were evaluated preoperatively, 13 and 30 days postoperatively. Sample size calculation indicated that 102 women had to be included. The incontinence status was estimated by a Danish version of the ICIG questionnaire; further, visual analogue scale, dynamometer for hand grip, knee extension strength and balance were applied. Work capacity was measured ergometer cycle together with lean body mass by impedance. Quality of life was assessed using the SF-36 questionnaire. Patients were examined preoperatively and twice postoperatively.
Results: In total 41 women improved their incontinence after hysterectomy and 10 women reported deterioration. Preoperative stress incontinence correlated with BMI (r = 0.25, p < 0.01) and urge incontinence with age (r = 0.24, p < 0.02). Further, improvement after hysterectomy in stress incontinence was associated with younger age (r = 0.20, p < 0.04). Improvement in urge incontinence was positively associated with BMI (r = 0.22, p = 0.02). A slight but significant loss was seen in lean body mass 13 and 30 days postoperatively.
Conclusions: Hysterectomy was not significantly associated with the risk of incontinence; in particular, when no further vaginal surgery is performed. Hysterectomy may even have a slightly positive effect on incontinence and de-novo cure.
