Background: Extracorporeal shockwave lithotripsy (ESWL) has proved to be effective in treating ureterolithiasis. This study aimed to investigate the predictive factors related to success ESWL among patient presented with renal stone. Methods: A retrospective study was conducted among 40 patients who underwent ESWL at the urology department, Baquba Teaching Hospital, Diyala University, Iraq. Data was collected between1st October 2018 and 31st January 2019 for renal stones diagnosed by non-enhanced spiral computed tomography (NCCT). The success rate defined as no stone or the remnant stones < 4 mm. We analyzed predictive factors by using multiple linear regression. Results: The success rates ranged from 50-90%. In the univariate analysis, body mass index (BMI), skin-to-stone distance (SSD)and the renal stone-attenuation value (in Hounsfield units, HU) were found to be significantly correlated with the outcome of ESWL (p<0.05). However, in the multiple linear regression, only the HU (B = -0.619, P < 0.0001; 95% confidence interval [CI]:0.03 to 0.07) was theindependent predictive factor. Conclusion: Hounsfield Unit is an independent predictive factor influencing the success of ESWL for treating renal stones.

The Impact

To evaluate the impact of ureteral stenting history to the outcomes of extracorporeal shockwave lithotripsy, we retrospectively analysed patients who underwent shockwave lithotripsy with Dornier Gemini lithotripter between September 2010 and August 2012. Forty seven patients (group A) who had a double J stent which was removed just before the procedure were matched-paired with another 47 patients (group B) who underwent shockwave lithotripsy having no stent history. The correlation between ureteral stenting history and stone-free rates was assessed. Stone-free rates were 68.1% and 87.2% for patients of group A and B, respectively (p=0.026). Postoperative complications were not different between groups. Multivariate analysis revealed that stone size (p=0.007), stone location (p=0.044) and history of ureteral stenting (p=0.046) were independent predictors for stone clearance after shockwave lithotripsy. Ureteral stents adversely affect shockwave lithotripsy outcome, even if they are removed before the procedure. Stenting history should divert treatment plan towards intracorporeal lithotripsy.
