“…The presence of hydronephrosis and stone clearance is controversial. Some studies have shown no significant differences 26,27 and others show a higher stone clearance 17,28 in the absence of hydronephrosis. The mechanism of high clearance rate in absence of hydronephrosis is because of the impedance of shockwave in presence of water, and mechanical movement of stone after shock wave; and, also the functional status of the kidney to clear the stone is affected by hydronephrosis.…”

“…Various studies have reported a higher clearance rate for smaller stones after ESWL, and it decreases gradually with the increase in size and density. 10,[15][16][17] Studies have shown that stone disintegration occurs better when the focal diameter of the shock-wave generator is larger than the stone size. This is because the mechanism of stone fragmentation depends on various factors like squeezing or circumferential quasistatic compression, the Hopkinson effect, shear force, and cavitation.…”

“…However, other studies have shown better clearance in the renal pelvis and upper ureter. 13,17,25 The difference could be due to stone characteristics and the presence of hydronephrosis. Another possible explanation for low overall clearance in the present study (48/79, i.e.…”

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.

“…The number of ESWL sessions for patients with a partial response is also controversial. In one study that involved 122 patients, 69.7% of patients became completely stone-free after a maximum of four sessions of ESWL [ 15 ]. The timing of ESWL sessions is also controversial.…”

Extracorporeal shock wave lithotripsy (ESWL) is considered a safe, reliable, and non-invasive modality for kidney stone management. However, there are well-established complications related to ESWL documented in the literature in the form of renal and extrarenal complications. Skeletal complications related to ESWL are rarely recorded; as far as we know, there is only one documented case report of an ESWL-related burst vertebral fracture seen in an osteoporotic patient, diagnosed as granulomatous spondylitis. Here, we present a novel case of a transverse process fracture of the third lumbar vertebra related to ESWL in a young patient otherwise free from any medical illness.
