Erector spinae plane block prior to extracorporeal shock wave lithotripsy decreases fluoroscopy time and promise a comfortable procedure for renal stones: A prospective randomized study.

[{"label":"INTRODUCTION AND OBJECTIVES","text":"To compare the efficacy of erector spinae plane block (ESPB) and intramuscular (i.m.) diclofenac sodium in regard to pain management and impact on stone-free status in patients undergoing SWL."},{"label":"PATIENTS AND MATERIALS","text":"The study included patients who underwent SWL for kidney stones in our institution. The patients were randomly assigned to the ESPB (Group 1: n\u202f=\u202f31) and i.m. 75 mg diclofenac sodium (Group 2: n\u202f=\u202f30) groups. The demographic data of the patients, fluoroscopy time during SWL, number of need of targeting, total shocks given, voltage, stone free rates (SFR), analgesy method, number of SWL sessions, VAS score, stone location, maximum stone size, stone volume and Hounsfield unit (HU) were also recorded."},{"label":"RESULTS","text":"A total of 61 patients were included the study. There was no statistically significant difference between the two groups according to stone size, volume and density, SWL duration, total shocks given, voltage, BMI, stone-free status and stone location. Fluoroscopy time and number of need for stone targeting were significantly lower in group 1 than group 2 (p\u202f=\u202f0.002, p\u202f=\u202f0.021, respectively). The VAS score was significantly lower for group 1 compared to group 2 (p\u202f<\u202f0.001)."},{"label":"CONCLUSIONS","text":"We observed that the VAS score was lower in the ESPB group compared to i.m. diclofenac sodium group and although it was not statistically significant, we achieved a higher rate of stone-free status in the first session in ESPB group. Most importantly, the patients in the ESPB group were exposed to less fluoroscopy and radiation."},{"copyright":"Copyright \u00a9 2023 The Author(s). Published by Elsevier Espa\u00f1a, S.L.U.
