“…The same ratio was also reported by Bozkurt, Wiesenthal, Chung, Keshvari, and El-Nahas [5,[10][11][12][13], and an almost identical one by Junuzovic [14]. The Chi-square test showed no significant differences between the male and female patients in the success rate of ESWL, which was consistent with the finding of Tavakkoli [15]; whereas, Gupta and Park reported a higher rate of ESWL success in male patients [8,16].…”

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.

“…Because there was a significant positive correlation between stone size and number of treatments in the total sample, respectively, as the stones was larger needed higher number of treatments [9]. Contrary to that interesting results are presented by Tarawneh and colleagues, who proved an inverse correlation between the performance of ESWL and size of the stone [17].…”

“…Three variables were significantly affecting the success rate namely stone size, number of shock waves and location of stone. [9] have shown that there are no statistically significant correlation between the number of treatments and localization of stones in the ureter, as well as a statistically significant correlation between the size of the stone and the localization of calculus in the ureter. [10] perform (ESWL) of pancreatic stones in eight patients with chronic pancreatitis and a dilated duct system harboring stones 5 to 20 mm (3 × 10 (SD) 5 mm) in diameter.…”

In the present study, investigation of extracorporeal shock wave lithotripsy in Zakho City for breakdown kidney and ureteral stones has been carried out. The data were collected from the center of breakdown kidney stones in Zakho hospital. A total of 34 patients (25 male and 9 female) of ages ranged from 20 -60 years were treated with ESWL. The patient harboring 24 renal stones and 10 ureteral stones of size ranged from 7 to 23 mm of almost patients are 8 mm and composed of calcium oxalate. The study has been conducted taking in to consideration the parameters (type, sizes, composition and location of stone as well as region and ages of patients, also power, number of shock wave and session). The results show that the number of shock wave decreases nearly exponentially with the ages of patients for calcium oxalate stone of size 8 mm under constant power 4 watt while it tends to increase according to increasing stones size for the patients of ages 20 -30 years. The size of calcium oxalate stones decreases nearly exponentially with the patients' ages for workers in Zakho city. Also for same size 8 mm of (calcium, phosphate, and oxalate) stones and different regions of zakho city, the number of shock waves decreases according to increasing ages of patients. Contrary to that for certain size of stones 8 mm, the number of shock wave starts to increase from uric acid to maximum value for calcium oxalate stone for the adult patients of age's 22 up to 30 years. However for elders ages 30 -60 years and different regions, the size of renal and ureteric stones increases from the minimum value for calcium, phosphate, oxalate to maximum value for calcium oxalate stone only. Uric acid stone requires minimum power to break, while the calcium oxalate needs maximum power to fragment due to its hardness composition. Later number of session of shock wave required for crushing each stones size increases according to increasing its size while its variation due to enhancing patients ages for calcium oxalate of size 8 mm results in nearly a decreasing exponential behavior.

“…2 The successful rate of ESWL as the treatment of all urinary tract stone was 96%. 3 Another supporting research showed, about 87% stone free rate was achieved after three months follow up in urethral stone treatment by using ESWL and no major complications found. 4 The aimed of this study was to describe the urinary stone characteristic in male and female patient who underwent ESWL at CMH, Jakarta, during [2008][2009][2010][2011][2012][2013][2014].…”

“…Recent studies have shown that stone made of calcium oxalate dihydrate are easier to break rather than uric acid stone. 3 Studies made by Tarawneh stated that there were positive correlation between stone size and number of ESWL treatment. 23 This study result also showed, that the number of male patients who come for continued treatment was higher than female patients.…”
