This clinical trial aims to investigate the analgesic efficacy of several perioperative pain management strategies-specifically, epidural analgesia, paravertebral blockade, transversus abdominis plane (TAP) block, intravenous patient-controlled analgesia (PCA), and intrathecal morphine-in patients undergoing a range of urological procedures. These procedures include pediatric circumcision, hydrocelectomy, inguinal hernia repair, renal cyst excision, and transurethral resection of the prostate. The trial will also evaluate the safety profiles of two specific local anesthetics, liposomal bupivacaine and ropivacaine. The primary research question is whether these different analgesic techniques reduce postoperative opioid requirements in patients undergoing urological surgery. A secondary question explores the adverse events associated with the use of liposomal bupivacaine and ropivacaine in this population.
Participants will be:
Urological surgery patients undergoing one of the aforementioned procedures. These participants will be randomized to receive one of the following pain management modalities: epidural analgesia, paravertebral blockade, TAP block, intravenous PCA, or intrathecal morphine. Patient assessments will be conducted in the post-anesthesia care unit (PACU) and at 2, 6, 12, and 24 hours postoperatively. Outcome measures will include: Numeric Rating Scale (NRS) pain scores, total postoperative analgesic consumption, recovery status, patient satisfaction, and time to return of bowel function.
