Introduction: The aim of the study was to observe the success rate of extracorporeal shock wave lithotripsy (ESWL) in the management of upper urinary tract stones. Materials and Methods: This retroprospective study was conducted in Pokhara Kidney stone Centre, Pokhara, Kaski, Nepal from January 2017 to January 2018. Seventy nine patients were selected in this study with upper urinary tract stone, size less than 20 mm. Results: Seventy four (93.67%) patients were successfully treated in initial use of shock wave and 5 (6.32%) patients required repetition. Conclusion: Overall satisfactory success rate was observed using ESWL for the upper urinary tract stone. Careful selection of patient, stone size and Hounsfield unit (HU) is advisable.

Introduction: The aim of this study is to assess the efficiency of extracorporeal shock wave lithotripsy (ESWL) in the treatment of residual kidney stones after the first treatment of the upper urinary tract calculus. Patients and Methods: 110 patients with residual kidney stones were treated with a MZ.ESWL.VI lithotripter. They were analyzed with regard to stone size, number of stones, number of ESWL sessions, retreatment rates, stone free rates. Results: 68,2% of patients became stone free within 3 months after ESWL with the average number of 3,44 sessions of treatment. No complication has occurred during all treatment. Conclusion: ESWL is an effective method in managing the residual kidney stones after the first treatment of the upper urinary tract calculus.

Background: Extracorporeal shock wave lithotripsy (ESWL) is an effective non-invasive method for managing urinary tract calculi. Present study was undertaken to evaluate factors that may influence ESWL clinical outcomes in Indian patients with urinary tract calculi.Methods: This prospective study was conducted at Department of Urology, Medical Trust Hospital Cochin, India in the period from September 2006 to March 2009. Sixty patients with upper urinary tract lithiasis having stone size between 5 to 25 mm were included and patients with ˃2 calculi, distal ureteric obstruction (not relieved), renal anomalies were excluded. All patients were treated with DIREX medical system lithotripter. Clinical outcome of ESWL was assessed by factors like site, size, density and skin-to-stone distance. After statistical analysis, p-value ≤0.05 was taken as the level of significance.Results: The overall success of ESWL was 82%. The final success of ESWL for sites like ureter, pelvis, mid or upper and lower calyx were 94.1%, 84%, 85.7% and 58% respectively (p = 0.095). The rate of fragmentation of stone after one session of ESWL for stone size ≤10 mm, 11 mm - 20 mm and ≥21 mm was 76.5%, 68.4% and 16.7% respectively (p=0.009). For stone density 751-1000 HU, 22.2% patients required ≥2 sessions to achieve stone free status (p<0.0005). Around 15.6% patients in skin-to-stone distance (SSD) ≤10cm required ≥2 sessions to achieve stone free status (p = 0.27).Conclusions: ESWL should be considered a primary modality of treatment in patients with calculi size ≤20 mm, density ≤ 1000 HU, pelvic, ureteric and upper and/or middle calyceal calculi and for SSD ≤10 cm.

Objective: To evaluate the success of extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteric calculi and determine the factors which influence outcome. Patients and methods: A retrospective audit of patients with a single ureteric stone receiving ESWL was performed. Success was defined as complete stone clearance on post-treatment imaging. Patient demographics and stone characteristics were correlated to ESWL outcome. Results: 108 patients met the inclusion criteria for this study. The mean age of the patients was 52.5 years (range 24–89 years). 80% (86/108) of patients were male. Stone sizes varied from 4 to 19 mm (mean 7.92 mm). The overall ESWL success rate for ureteric stones was 79%. Treatment was more effective for smaller ( p = 0.003) and more located stones ( p = 0.035). Stone size correlated with number of treatments required ( p =0.005). A JJ stent in situ at the time of ESWL reduced the success rate ( p = 0.002). Conclusions: Stone size, site in the ureter, and the presence of a JJ stent were predictors of ESWL success. Our study from a District General Hospital in the UK demonstrates that ESWL may be used with high efficacy to treat ureteric stones.
