Uterus Preservation in Case of Vaginal Prolapse Surgery Acts as a Protector against Postoperative Urinary Retention

Background: The aim of this study was to identify clinical risk factors for increased post-void residual (PVR) volumes in patients undergoing vaginal prolapse surgery and to find out whether uterus preservation or prolapse hysterectomy influences the incidence of postoperative urinary retention. Methods: This retrospective study included women who presented with pelvic organ prolapse (POP) and planned prolapse surgery between January 2017 and July 2019. PVR was assessed postoperatively and increased amounts were defined as incomplete voiding with residual urine volume greater than 150 mL. Results: Increased PVR at the first postoperative day occurred in 31.8% (56/176). Body mass index (BMI) was significantly lower in patients with increased PVR after pelvic floor surgery compared to patients with normal PVR amounts (p = 0.040). Furthermore, during multiple logistic regression analysis, low BMI (p = 0.009) as well as prolapse hysterectomy (p = 0.032) turned out to be the strongest risk factors associated with increased PVR volume. Conclusion: This is the first study identifying prolapse hysterectomy as an independent risk factor for increased PVR after surgical prolapse repair. Our results might be helpful in counseling patients prior to surgery and underline the option of uterus preservation during prolapse surgery in selected cases.

A New Surgical Method of U-Shaped Myometrial Excavation and Modified Suture Approach with Uterus Preservation for Diffuse Adenomyosis

Objective. To evaluate the feasibility, safety, and efficacy of a new surgical method of U-shaped myometrial excavation and modified suture approach with uterus preservation for diffuse adenomyosis. Methods. From January 2012 to December 2014, 198 patients with diffuse adenomyosis were surgically treated using this novel procedure in Zhengzhou Hua-Shan Hospital. Degree of dysmenorrhea, menstrual blood volume, serum CA 125, and uterine size before and at 1 month, 3 months, 6 months, 12 months, and 24 months after surgery were compared. Results. Postoperatively, VAS score of dysmenorrhea, menstrual blood volume, serum CA 125 level, and uterine size significantly decreased at 1 month, 3 months, 6 months, 12 months, and 24 months from presurgical levels (all p < .001), but there were no differences at the follow-up time points. Two patients recurred at 18 months and 23 months after surgery, but both recovered after repeat surgery. Interestingly, 2 other patients recrudesced at 10 months and 12 months after surgery. In addition, only one patient was found to have a postoperative anaemia with fever, conservatively managed without surgery. Conclusion. U-shaped myometrial excavation and modified suture approach with uterus preservation is a safe and feasible surgical approach to treat diffuse adenomyosis, with favourable outcomes.
