An interventional study of Bupivacain (Postoperative) and Placebo in Pain After Surgery, PSP and Chronic Pain Syndrome, sponsored by Hadassah Medical Organization. Not yet recruiting. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-06-23.
Sponsored by Hadassah Medical Organization · Not applicable, Interventional, and Prevention
This randomized, double-blind controlled trial will evaluate whether intraoperative injection of bupivacaine at the sling insertion site reduces postoperative pelvic and thigh pain in women undergoing TVT or TVT-O surgery for stress urinary incontinence. Women aged 18 years and older scheduled for vaginal surgery including a mid-urethral sling procedure will be randomly assigned to receive either 0.5% bupivacaine or saline injection at the surgical site at the end of the procedure.
Postoperative pain will be assessed using the Numerical Rating Scale (NRS) within 24 hours after surgery, at one month, and at least six months postoperatively. The study will also evaluate opioid consumption and examine the relationship between early postoperative pain and the development of chronic postsurgical pain. The results may help determine whether local anesthetic injection during sling surgery can improve short- and long-term pain outcomes.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants undergoing TVT or TVT-O surgery for stress urinary incontinence will receive a 5 mL injection of 0.5% bupivacaine into the trans-obturator/levator ani muscle sling insertion site at the end of the procedure. All participants will receive standard postoperative care, including systemic analgesics as needed.
Drug: Bupivacain (Postoperative)
Participants undergoing TVT or TVT-O surgery for stress urinary incontinence will receive a 5 mL injection of normal saline into the same surgical site at the end of the procedure. All participants will receive standard postoperative care, including systemic analgesics as needed.
Other: Placebo
A 5 mL injection of 0.5% bupivacaine will be administered into the trans-obturator/levator ani sling insertion site at the end of the TVT or TVT-O procedure, prior to wound closure.
Participants will receive a 5 mL injection of sterile 0.9% normal saline into the trans-obturator/levator ani sling insertion site at the end of the TVT or TVT-O procedure, prior to wound closure.
Postoperative pain intensity assessed using the Numerical Rating Scale (NRS, 0-10 scale)
Pain intensity will be evaluated using the 11-point Numerical Rating Scale (NRS), where 0 represents no pain and 10 represents the worst pain imaginable. Assessments will be performed during hospital recovery (within 12-24 hours after surgery), at 1 month, and at 6 months postoperatively to evaluate both acute and chronic postsurgical pain.
Time frame: Within 24 hours after surgery, at 1 month, and at 6 months postoperatively

Start is estimated for Jul 2026; primary completion for Jul 2027, 12 months later.
Of 3,731 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 12 months is above that.
Counting every sponsor, half of 3,830 studies reached it within 10 months; a quarter within 4 and three quarters within 23.
