Patients undergoing buccal urethroplasty will often have significant post-operative oral pain from the graft site. Various graft harvest techniques and methods for post-harvest hemostasis including graft site closure have been explored. Despite the frequency of this clinical scenario there is no established best practice for peri-operative pain management in this patient population. In addition to traditional post operative pain control, groups have sought various peri-operative anesthetic regimens to improve post operative pain. This has led recently to the description of various regional blocks including buccal and periorbital blocks for peri-operative local anesthetic. No study has looked at superiority of regional pain management in this patient population. This study will aim to assess three established anesthetic protocols for oral pain control in a blinded, randomized controlled trial.
Hypothesis: Patients who have buccal block will have lower post op pain without any increase adverse oral outcomes.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Urethral Stricture, Male | Drug: Standard Buccal Harvest Drug: Basic buccal procedure + Long acting local Drug: Basic buccal procedure + Buccal block | Phase 3 |
This is a blinded, randomized, controlled trial following patients undergoing buccal urethroplasty (see criteria). This study will aim to assess three established anesthetic protocols for oral pain control. Each study arm holds equal weight. Approximately 60 subjects will be randomized in a 1:1:1 ratio to receive the following graft harvest techniques, which are all considered standard of care.
Group 1: Current Buccal Harvest
- Infiltration of lidocaine 1% with 1:100,000 epinephrine (maximum 10cc)
- Graft site hemostasis with monopolar cautery
- No suture closure of graft site
Group 2: Basic buccal procedure + Long acting local
- Infiltration of lidocaine 1% with epinephrine (maximum 10cc)
- Graft site hemostasis with monopolar cautery
- No suture closure of graft site
- 0.5% Marcaine (maximum 5cc) at case conclusion
Group 3: Basic buccal procedure + Buccal block
- Infiltration of lidocaine 1% with epinephrine (maximum 10cc)
- Graft site hemostasis with monopolar cautery
- No suture closure of graft site
- Buccal block with 0.5% Marcaine (maximum 5cc) at case conclusion
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 60 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | This is a blinded, randomized, controlled trial following patients undergoing buccal urethroplasty (see criteria). This study will aim to assess three established anesthetic protocols for oral pain control. Each study arm holds equal weight. |
Masking: | Triple (Participant, Investigator, Outcomes Assessor) |
Masking Description: | Approximately 60 subjects will be randomized in a 1:1:1 ratio to receive 3 different local anesthetic regimens following buccal graft harvest. The care provider administering will not be masked to the type of block, but they will be blinded to the post op outcomes. |

- Change(s) in Post-operative pain [ Time Frame: Postoperative Day 1, 5, 10 ]
The Wong-Baker FACES pain scale is a validated scale where a score of 0 is no pain and 10 is the worst pain imaginable. Pain greater than or equal to 5 would result in significant limitations on daily life.
Oral, incisional (surgical site), and overall pain will each be assigned a score of 0-10 at each time point (9 total scores).
- Change(s) in Post-operative Narcotic use [ Time Frame: Postoperative Day 1, 5, 10 ]Patient measure of number of oxycodone tablets taken (0-5). Patient request for additional narcotic medicaiton (Yes/No) Patient measure of adherence to non-narcotic pain regiman (Yes/No)
- Peri-operative Complications [ Time Frame: Postoperative Day 0-30 ]Clavien-Dingo is a validated tool to measure the severity of post-operative outcomes. Class I are mild and require no treatment. Class V is death.
