Liposomal Bupivacaine vs. Bupivacaine Hydrochloride and Lidocaine During Suburethral Sling Placement

This is a prospective, comparative, randomized study. Women with pure stress urinary
incontinence or mixed urinary incontinence with a predominant stress component who had chosen
to proceed with a midurethral sling will be randomized to two groups. The study group will
have the hydro-dissection performed with a diluted liposomal bupivacaine solution. The
comparison group would have the hydro-dissection performed with a diluted bupivacaine HCL and
Lidocaine solution. The postoperative pain will be compared between groups using a visual
analog scale. The quality of recovery will be compared between the groups using the quality
of recovery short form. Postoperative opioid consumption will be compared between the two
groups.
