Numbing shot during sling surgery may ease Post-Op pain

This study tests whether injecting a numbing medicine (bupivacaine) into the surgical site during sling surgery for stress urinary incontinence can reduce pelvic and thigh pain after the procedure. Sixty women will be randomly assigned to receive either the numbing medicine or a placebo (salt water) injection. Their pain levels will be checked within 24 hours, at one month, and at six months after surgery to see if the injection helps both short-term and long-term pain.
