Objectives: To evaluate the factors that affect the success rate of ESWL for treatment of renal stones and to estimate the prevalence of stone recurrence during a 1-year period. Materials and Methods:During the period of January, 2010 and December, 2010, prospective study of 142 subjects with single or multiple renal stones (<30 mm, largest diameter) undergone ESWL monotherapyby Siemens-LITHOSKOP lithotriptor. The results of treatment were assessedafter a follow-up period of 3 months. Treatment success was a complete clearance of the stones or presence of insignificantresidual fragments<4 millimeters. Correlation of the success rate with the characteristics of the subjects, conditionsof the urinary tract and features of the stone was done.Results: During the 3-months follow-up period, the success rate was 111/142 (78%). Re-treatment was needed in 75 patients (52.8%). Post-treatment procedures were done in 12 subjects (8.4%). Post-ESWL complications were observed in 5 subjects (3.5%). Out of 10 prognosticfactors studied, 5 had a powerful influence on the success rate, which are: renal morphology, presence of congenital anomalies, size of stone, site of stone and treated stones number. Other factors including age, sex, nationality, stonenature (de novo or recurrent) and ureteric stenting had no significant impact on the success rate. Conclusions:Prediction of success of treatment with ESWL and the recurrence depends and may be predicted by renal morphology, presence of congenital anomalies, size of stone, site of stone and treated stones number.

Introduction: Kidney stone is a prevalent disease, especially in desert and arid areas like Rafsanjan in Iran. Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive treatment of kidney stones that success rate of which depends on various factors. This study aimed at investigating predictive variables of success in ESWL in patients referred to the ESWL Unit of Moradi hospital (Rafsanjan, Kerman, Iran) in 2016. Methods: All patients referred to the ESWL unit in the hospital during a 6-month period in 2016 were included in this study. Demographic information, size, location, and orientation of stones were collected from interviews and sonography observations. Finally, the obtained data was investigated with the statistical Chi-square and logistic regression tests. Results: The male to female ratio in patients with kidney stones was almost 2:1, and the overall estimated rate of lithotripsy was 71.7%. There was no difference between the male and female patients in the success of lithotripsy and, in addition, stone location did not affect the rate of success. The only successful predictor of ESWL was stone size. The larger stones were more successful broken than smaller. Conclusions: Stone size plays an important role in the selection of treatment method. Breaking of larger stones is more successful in ESWL due to the greater absorption of ultrasonic energy emitted by the machine and because of the more accurate determination of their location.

Prediction of success rate after extracorporeal shock‐wave lithotripsy of renal stonesA multivariate analysis model

Abstract: Patient age, stone size, location and number, radiological renal features and congenital renal anomalies are prognostic factors determining stone clearance after ESWL of renal calculi. Our regression model can predict the probability of the success of ESWL with an accuracy of 87%.
