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.

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.
