Abstract
Introduction: Extracorporeal shock-wave lithotripsy (ESWL)is an established non-invasive treatment modality for renaland ureteric stones. However, treatment outcome and efficacydepends on multiple factors like stone size, location and typeof machine used. We aimed to assess efficacy of ESWL asa primary treatment modality in renal and ureteric stones ina busy hospital setting having significant renal stone diseaseburden.Material and methods:1187 patients who underwent ESWLbetween January 2015 to December 2016 in our departmentwere included in the study. Patients with nephrolithiasis andureterolithiasis having functional kidney, without any absolutecontraindication to ESWL were included. Dornier Med TechCompact Delta 2 machines were used for all the patients.Stone localization was done using both fluoroscopic andultrasound- guided methods by same expert.Results: Out of 1187 patients,887 patients had solitary renalstones,170 had solitary ureteral calculus and 130 patients hadmultiple renal calculi. Stone size ranged from 8mm–20mm.Renal pelvic stones, upper calycial stones and proximalureteric stones had stone free rate of 84%,86% and 82.5%respectively. 89% and 84% of patients were stone free whensize of stone was between 8-12mm, it decreased to 77% and73% when size increased between 13-16mm for kidney andureteric stones respectively.Conclusions: ESWL is an effective primary treatmentmodality for appropriately selected patients with stone sizeless than 2 cm in favorable location with a normal functioningkidney. Use of both fluoroscopic and ultrasound imagingimproves localization of stones thus improving success. Itis an important modality in hands of urologist treating hugevolume of urolithiasis patients in busy hospitals with longwaiting list and with limited resources.
