SHORT-TERM SURGICAL AND FUNCTIONAL OUTCOMES AFTER ROBOT-ASSISTED SACROCOLPOPEXY IN A SINGLE INSTITUTION

Abstract

(Objectives) This study aimed to evaluate the surgical outcomes and functional parameters of lower urinary tract and bowel symptoms in patients who have undergone robot-assisted sacrocolpopexy (RASC) due to pelvic organ prolapse. (Patients and methods) This retrospective study included 110 consecutive RASC cases in the urology department of Ageo Central General Hospital, Japan, from November 2020 to October 2021. The medical records of these patients were retrieved. Data on uroflowmetry, post-void residual urine test, and self-administered questionnaires on urination and defecation were assessed. (Results) The mean operating time was 146 min, and the estimated blood loss was 14.8 ml. The intraoperative, postoperative, and severe complication rates of cases classified as Clavien-Dindo grade IIIa or higher were 0%, 9.1%, and 0%, respectively. The maximum flow rate and post-void residual volume of urine significantly improved after the operation. Similarly, the quality of life (QOL) scores and overactive bladder symptom score (OABSS), as well as the responses for the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Urinary Distress Inventory-6 (UDI-6), significantly improved one month after the operation and were sustained for six months. On the other hand, the total scores from the Constipation Scoring System (CSS) and the subscales of the Patient Assessment of Constipation (PAC) -QOL worsened. These scores, except for those of the PAC-QOL satisfaction subscale recovered to the preoperative levels; the PAC-QOL satisfaction subscale scores significantly improved six months postoperatively. The rates of de novo overactive bladder (OAB), stress urinary incontinence (SUI), and constipation one month postoperatively were 8%, 33%, and 10%, respectively. (Conclusions) RASC was performed safely in our institution with acceptable postoperative lower urinary tract and bowel outcomes.
