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.
Postoperative pain, the quality of their recovery and the opioid consumption following a midurethral sling placement are being compared between 2 groups. One group will have the hydro-dissection performed with a diluted liposomal bupivacaine solution. The other group will have the hydro-dissection performed with a diluted bupivacaine HCL and Lidocaine solution.
