Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 42
Healthy volunteers: no

Brief summary:
There are many ways to perform a suprapubic approach pubovaginal sling. Some surgeons inject local pain medical into the retropubic space before placing the sling, others do not. This study is to determine if injection of local pain medication into the retropubic space before placing a mid-urethral sling for urinary stress incontinence results in lower postoperative pain scores, lower use of postoperative narcotic medication and lower rates of urinary retention.

Detailed description:
To evaluate if an injection in the retropubic space with a local acting anesthetic, Marcaine, (bupivacaine) at the time of mid-urethral sling placement will improve patients' reported post operative pain and decrease the use of narcotic pain medication. This study will include all female patients age 18 and older who will undergo a mid-urethral sling with or without anterior repair for the treatment of urinary stress incontinence by a member of the Division of Urogynecology and Reconstructive Pelvic Surgery who consent to be in the study.

Once patients have consented to participate in the study they will be randomized into two groups. One group will have the mid-urethral sling placed in the usual fashion with no injection of local anesthetic. The other group will have the mid-urethral sling placed after the retropubic space has been infiltrated with local anesthetic as previously described in the literature. Pain will be assessed with the use of a Visual Analog Scale during the hospitalization and the use of narcotic pain medication will be assessed during recovery and overnight in the hospital. Patients will be asked to record how often and what type of pain medication they use. Patients will also be asked to keep a log of their urination if they are discharged home with self catheterization. They will be asked to mail in their pain medication log and voiding diary (if needed) at a two-week post-operative. Outcomes will then be compared.

Arms:
arm 1: Patients randomized to this arm will receive 60 cc of 0.125% Marcaine injected into the retropubic space along the tract that the suprapubic mid-urethral trocar will follow (one on each side) for a total of 120 cc of 0.125% Marcaine, prior to the placement of the mid-urethral sling via the suprapubic approach. arm 2: Patients assigned to this arm will have the mid-urethral sling placed via the suprapubic approach in the standard fashion with no injection of Marcaine into the retropubic space.

Interventions: intervention 1: 0.125% Marcaine
Intervention descriptions: intervention 1: Patients randomized to the intervention arm will receive 60 cc of 0.125% Marcaine injected into the retropubic space along the tract that the suprapubic mid-urethral trocar will follow (one on each side) for a total of 120 cc of 0.125% Marcaine, prior to the placement of the mid-urethral sling via the suprapubic approach.
