Stone Clearance Rate Between Extracorporeal Shock Lithotripsy (ESWL) V/S Retrograde Intrarenal Surgery (RIRS) in Patients with Lower Calycx

Abstract

One of the techniques used most frequently to treat urolithiasis is shockwave lithotripsy (SWL). Extracorporeal shock wave lithotripsy (ESWL) and retrograde intra-renal surgery (RIRS) are recommended treatments for inferior calyceal (IC) calculi measuring 1-2cm. Objective: To compare the rate of stone clearance between extracorporeal shock wave lithotripsy (ESWL) and Retrograde Intrarenal Surgery (RIRS) in patients with lower calycx calculi. Methods: The randomized control trial of six months was conducted at LUH Jamshoro. Informed consent was gained when the procedure, risks, and advantages of the study were explained. The patients were divided into one of two groups at random: group A (ESWL) or group two (RIRS). A week later, the patient underwent a contrast-enhanced computed tomography (CT) scan, and the kidney stone was noted as having been removed. Results: The group A's mean age (SD) was 46.50 ± 14.73 whereas group B's mean age (SD) was 42.37 ± 16.07. The stone clearance was observed in 13 (43.3%) of group A's cases compared to 1 (3.3%) of group B's, with a highly significant p-value of (p=0.0001). Conclusions: In terms of stone removal among patients with lower calycx, a significantly significant difference among the use of extracorporeal shock wave lithotripsy and retrograde intrarenal lithotripsy was seen.
