Introduction: The innovation of outpatient extracorporeal shock wave lithotripsy (ESWL) has created a revolution in the treatment of urinary tract stones. Objectives: The aim of this study was to evaluate the success rate of electromagnetic lithotriptor, in the treatment of renal and upper ureteral stones. Patients and Methods: In this study, 84 patients aged over 10 years, with renal and upper ureteral stones less than 20 mm, were considered for ESWL. Patients were randomly assigned into two groups. In all patients, using ultrasound and fluoroscopy, stone was localized and using an electromagnetic machine by standard method, ESWL was performed with electromagnetic waves. ESWL started with 12 kV and was increased to18 kV, up to a maximum of 3500 shock waves. Two weeks later a kidney, ureter, and bladder (KUB) X-ray and ultrasonography was conducted and the success rate of lithotripsy according to the crushing of stones and decrease in stone size was measured and recorded. Results: In this study, 61.9% of patients were male. The mean age of patients was 46.62 ± 13.12 years. The mean size of stones in both groups was 13.4 ± 2.5 mm. Around 56.3% of patients had opaque stones and 43.8% had non-opaque stones. A total of 63.5% of patients received up to 3000 shock waves and 37.5% of patients received more than 3000 shock waves. Complete efficacy and clearance of renal and ureteral stones was observed in 54.8% and 59.1% of cases, respectively (P>0.05). Conclusion: This study showed a similarity in the success and efficacy of electromagnetic lithotriptor in the treatment of renal and upper ureteral stones. Additionally, the success rate of opaque and non-opaque stones have no significant differences, while stone size and proportion of shock waves will not increase the efficacy of the electromagnetic lithotriptor in crushing the stones.

“…Since its inception, ESWL has become the treatment of choice for both renal and upper ureteric stones. However, nowadays, with newer lithotripters and better imaging modalities, ESWL is also considered suitable for middle and lower ureteric stones as for renal and upper ureteric stones [ 8 ].…”

Objective To compare the non-contrast computed tomography (NCCT) scan-based parameters of ureteric stones affecting the outcome of extracorporeal shock wave lithotripsy (ESWL).Materials and methodsWe retrospectively evaluated the pre-procedure NCCT of 74 patients who had ESWL for solitary ureteric calculi of 5-20 mm in diameter. We assessed the age, sex, basal metabolic index (BMI), laterality, location, presence of double 'J' (DJ) stent, skin to stone distance (SSD), stone maximum diameter, Hounsfield unit (HU), Hounsfield density (HD), area, and volume. All those who had no stone on follow-up imaging within 30 days were declared successful while those who had residual stone were declared failures.ResultsThe overall success rate was 78% (58/74). Sixty (81.1%) patients were male. The success of ESWL was correlated with lower SSD, Hounsfield units (HU) and Hounsfield density (HD). However, in multivariate analysis, SSD, Hounsfield unit, and stone area showed correlation with success of procedure but Hounsfield density failed to show correlation. The success rate in patients with stone HU <500, 500-1000 and >1000 were 93.9%, 69%, and 58.3%, respectively. Patients with lower BMI (<30 kg/m2) and HD (<76 HU/mm) were more prone towards success of the procedure than those with higher BMI (>30 kg/m2) and higher HD (>76 HU/mm).ConclusionBMI, SSD, stone Hounsfield units and Hounsfield unit density were strong predictors of outcome of ESWL for ureteric stone.
