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.\n\nParticipants will be:\n\nUrological surgery patients undergoing one of the aforementioned procedures.
