Flexible Ureterorenoscopy Versus Extracorporeal Shock Wave Lithotripsy for Treatment of Lower Pole Renal Stones

Abstract

Background: Urolithiasis affects 5-15% of the world population, with high recurrence, (2) which at 5 years can be up to 50%, with high frequency in the labor force population, which produces a high individual and hospital cost, so it constitutes a health problem of high socio-sanitary interes. Objective: To compare the treatment outcomes of Flexible ureterorenoscopy and extracorporeal shock wave lithotripsy for patients with lower pole stones. Patients and method: Data base review for the patients in the period from first of Jan 2018 to the end of June 2019, in which 131 patients underwent interventions for the management of small lower pole stone. Sixty-seven patients were treated by ESWL and the rest (64) treated by F-URS. The most common complication was UTI 9/19 Results: 86/131 were male and 45/131 were female with mean age for F-URS group (52±9.7 years) and (49.6±12.3 years) for ESWL group, with highly significant differences regarding the stone size between the studied groups. The treatment rate, operative time and procedure per patient were highly significantly decrease in F-URS group than in ESWL (p<0.001). Moreover, significant association were notice between the studied groups among SFR at 3 months and secondary procedures. Conclusion: lower pole renal stone in size between 10-20 mm treated successfully and more efficiently by F-URS in comparison with ESWL.
