About

The investigator's study aims to see if an enhanced recovery regimen of pain medications before and during surgery will decrease the use and risk of opioid pain medications as well as improve pain control in anterior urethroplasty patients. Participants will be randomized to one of two pain regimens (enhanced recovery regimen vs standard regimen).

Full description

The purpose of this study is to assess the difference in narcotics usage between two different pain management protocols after urethroplasty. Management at the current time varies between giving intraoperative painkillers along with peripheral nerve blocks in some patients, while others do not receive this protocol. In this study, one group will continue the historical standard of care of the hospital, receiving postoperative nonsteroidal anti-inflammatory drugs (NSAIDs) and narcotics for pain control. The other group will utilize a protocol to lower narcotics usage, including acetaminophen, gabapentin, Celebrex, and local anesthetic (bupivacaine) in an attempt to reduce the usage of narcotics postoperatively. Given the heightened concern over narcotic usage by postoperative patients, including the risk of chronic usage by even young patients, the objective will be to assess if using this protocol as a new standard can limit the need for postoperative narcotics prescriptions.

In related urological procedures, bupivacaine injections given before surgeries have been shown to significantly lower pain scores after surgery for patients undergoing penile prosthesis. The University of Alabama at Birmingham has also been using an Enhanced Recovery After Surgery (ERAS) protocol, a multimodal presurgical care pathway designed to achieve early recovery after surgical procedures, for cystectomy and seen reduced narcotic usage among those patients.

This study would potentially help determine a new pain management protocol for urology patients undergoing anterior urethroplasty that is both more effective and less risky.

48 participants in 2 patient groups

Standard Protocol

Active Comparator group

Description:

Patients will receive the historical standard for pain management, which may include narcotics during and after surgery. Postoperative prescriptions ibuprofen 800 mg, and acetaminophen 1000 mg to be taken on a scheduled basis then as needed. Another prescription for oxycodone will be given to be used only if needed.

Treatment:

Drug: Acetaminophen

Drug: Ibuprofen 800 mg

Drug: Oxycodone

Enhanced Recovery Protocol

Experimental group

Description:

A combination regimen of acetaminophen, Celebrex and gabapentin pre-op, with 30 mL of 0.5% bupivacaine and 4 mg of dexamethasone given as a perineal nerve block at the time of urethroplasty surgery. Narcotics will be administered judiciously and ass seen fit by the anesthesia and/or surgical teams. Postoperative prescriptions ibuprofen 800 mg, and acetaminophen 1000 mg to be taken on a scheduled basis then as needed. Another prescription for oxycodone will be given to be used only if needed.

Treatment:

Drug: celebrex

Drug: Acetaminophen

Drug: Dexamethasone

Drug: Gabapentin

Drug: Ibuprofen 800 mg

Drug: Bupivacaine

Drug: Oxycodone
