“…However, the success of ESWL in removing stones also depends on the specific location of the stone. 22 However, it is important to note that multiple sessions of ESWL may be required for successful removal. 23 In such cases where multiple sessions are necessary, other auxiliary approaches such as stenting may be beneficial.…”

Objective: To examined the efficacy of extracorporeal shockwave lithotripsy in the removal of small and large stones. Study Design: Observational prospective study. Place and Duration of Study: Department of Urology, Liaquat University of Medical and Health Sciences, Jamshoro from 1st January 2018 to 31st January 2019. Methodology: Two hundred patients, 139 males and 61 females, who underwent extracorporeal shockwave lithotripsy for stones were enrolled. The participants were separated into two groups based on stone size group A (stones measuring between 1.5 to 2.0 cm) and group B (stones measuring between 2.0 and 2.5 cm). Patients who were pediatric or had co-morbidities were excluded. The number of extracorporeal shockwave lithotripsy sessions and the number of beams per session were determined based on the clearance of the stones, if the radiology report indicated that the stones were completely cleared or if fragments smaller than 2 mm in diameter were present. Results: In group A, only 26 patients had partial clearance while in group B only 2 patients had partial clearance. The majority of the patients in both groups did not report any complications. The most common complaint was isolated haematuria, with 9 (4.5%) patients in the one session group, 16 (8%) in the two session group, and 5 (2.5%) in the three or more session group reporting this symptom Two patients in group A had hematoma along with haematuria, one patient in group A had massive haematuria that required transfusion, and one patient in each group reported having steintrasse with haematuria. In addition, one patient in group A had an isolated hematoma. Conclusion: Extracorporeal shockwave lithotripsy is effective and first-line treatment option for small renal stones. For ureteric stones, the location of stones should be taken into account, as this can have an effect on the stone-free rate and efficacy of extracorporeal shockwave lithotripsy.

“…Various studies in the published literature have reported the rate of stone clearance as high as 70-100% for density <500 HU, which decreases to 66-93% for 500-1000 HU and further decreases to 33-51% for >1000 HU. 13,14,22,23 In this study we also analyzed the sub-group of patients with a stone density of 500-750 HU and 751-1000 HU which showed a success rate of 88.5% (23/26) and 41.7% (20/48) respectively. The difference in stone clearance was significant (X2 value =14.1, p=0.0008) in a present study showing a stone clearance decreasing from 100% for <500 HU to 88.5% for >500-750 HU, and further decreased to 41.7% for >751 HU for the renal and upper ureteric stones.…”

Introduction: Extracorporeal shockwave lithotripsy (ESWL) is a day care, less invasive procedure not requiring anesthesia for the treatment of renal and ureteric stones. Method: This was a cross sectional study of retrospectively collected data on ESWL during May 2018 to January 2020 at the department of Urology, Bir Hospital, National Academy of Medical Sciences (NAMS), Nepal. The data on ESWL for renal and upper ureteric stone up to the size of 20 mm were included. Stone clearance was defined as stone fragment <4 mm on kidney ureter bladder (KUB) X-ray or ultrasonography (USG) during follow up at 1 - 3 mo. Ethical approval was obtained from NAMS ethical committee. Microsoft Excel was used for descriptive analysis of age, gender, stone size, density, location, hydronephrosis, and clearance. A Chi square test was used for association, and a p-value <0.05 considered statistically significant. Result: Out of 79 cases, overall stone clearance was 48(60.8%), 100% for <10 mm (14/14) and density <500 HU (5/5), and 80% for upper ureteric stone (4/5) and 74.1% for those without hydronephrosis (20/27). Patients in age group of 20-39 y accounted for 48(60.8%), males 52(65.8%), 52(65%) had 10-15 mm stones, 46(58.2%) in pelvis, 48(60.8%) density of 751-1000 HU, and mild hydronephrosis present in 44(55.7%). Conclusion: Stone clearance were highest (100%) for small stone <10 mm size and low density <500 HU. The stone clearance rate decreased as the size, density, and hydronephrosis increased.
