Anesthetics' role in postoperative urinary retention after pelvic organ prolapse surgery with concomitant midurethral slings: a randomized clinical trial

Introduction and hypothesis Spinal anesthesia can be a potential risk factor for postoperative urinary retention (POUR). Our objective was to compare POUR rates for outpatient vaginal pelvic floor surgeries when using spinal versus general anesthesia. Our hypothesis was that spinal anesthesia would have higher POUR rates compared with general anesthesia.
