Although percutaneous nephrolithotomy(PNL) is a minimally invasive procedure, it causes severe postoperative pain due to dilatation of the renal capsule and parenchymal duct and peritubal distension of the nephrostomy tube. PNL-related pain has a limited response to oral and intravenous treatments. The primary aim of our study is to investigate the effectiveness of the erector spinae plane block (ESPB) in pain management of patients undergoing PNL.~Our secondary aim is determining if any possible clinical effect of ESPB in terms of serial peak expiratory flow measurements, postoperative agitation score of the patient (Riker Score), ambulation time, length of hospital stay.
This study investigates the effectiveness of the erector spinae plane block (ESPB) in pain management of patients undergoing PNL.
