Objective  To explore the effect of postpartum pelvic floor rehabilitation training combined with pelvic floor rehabilitation instrument on prevention of urinary retention in puerperas.

  Methods  A total of 130 puerperas with vaginal delivery were selected and divided into control group and observation group, with 65 cases in each group. Both groups were treated with the same routine postnatal nursing. The control group was given conventional preventive treatment for urinary retention after delivery, while the observation group was given early pelvic floor rehabilitation training combined with pelvic floor rehabilitation instrument on the basis of the control group. The time to first urination, the amount of residual urine and the incidence rate of urine retention within 6 to 8 h after delivery were compared between two groups.

  Results  The time to first urination and residual urine volume of bladder in the observation group were significantly shorter and less than those in the control group (P < P < 0.05). The incidence rate of urine retention within 6 to 8 h after delivery in the observation group and the control group was 1.54% and 12.31% respectively, and there was a significant difference between two groups (P < P < 0.05).

  Conclusion  Pelvic floor rehabilitation training combined with pelvic floor rehabilitation instrument can shorten the time to first urination, reduce the residual urine of bladder, and effectively prevent urinary retention.
