Efficacy of ultrasound-guided transversalis fascia plane block in pediatric ureteroneocystostomy surgery

Ureteroneocystostomy to treat vesicoureteral reflux (VUR) in children. Although less invasive methods, such as laparoscopic or robotic surgery, have been developed, open surgeries are still commonly performed. Various medical treatments and regional anesthesia techniques have been used to treat post-surgical pain in children. The transversalis fascia is a structure that covers the inner plane of the abdominal muscles that includes the preperitoneal fat layer posteriorly. The transversalis fascia plane (TFP) block, which was first defined in 2009 to provide local anesthesia to this region, has been used to effectively manage pain in lower abdominal surgery The TFP block procedure, defined by Hebbard, aims to block the iliohypogastric and ilioinguinal nerves, which are the proximal branches of the T12 and L1 spinal nerves that run between the transversus abdominis muscle and the transversalis fascia The Face, Legs, Activity, Cry, Consolability (FLACC) scale is an observational pain rating method that was developed by Merkel et al. [3] in 1997 that is used to evaluate pain in children aged two months to seven years.
