RIRS (Retrograde Intrarenal Surgery) is safe and effective in aging male patients: A single surgeon experience

Abstract

Aim: Kidney stones are one of the most common diseases around the world. Used together with Extracorporeal Shockwave Lithotripsy(ESWL), Retrograde Intrarenal Surgery (RIRS) is the most common method used for kidney stones below 2 cm. The purpose of ourstudy is to evaluate the safety and efficacy of RIRS in aging male patients with kidney stones.Material and Methods: Our study contains 213 patients who underwent RIRS in Beylikduzu State Hospital between March 2017 andMarch 2019. Patients were examined retrospectively and divided in four groups according to their age [(between 40 and 49 for Group1), (between 50 and 59 for Group 2), (between 60 and 69 for Group3), (70 and above for Group 4)]. Demographic data, stone size andlocation, and American Society of Anesthesiologist (ASA) scores of patients have been recorded. Stone-free rate at postoperativemonth 3, hospitalization period, double J (DJ) stenting period, ESWL, or whether they have had a second operation have beenrecorded. ANOVA, Chi-Square tests were used in statistical analysis.Results: Stone characteristics and demographic data of four groups have been examined. Stone size was similar. ASA scoresincreased with increasing age as expected (p=0.001). Patients had similar mean operation period, hospitalization period and DJstenting duration, and no statistically significant difference was detected (p>0.05). Upon examining stone-free rate at postoperativemonth 3, still no statistically significant difference was determined (p>0.05). There was no need for perioperative blood transfusion.Conclusion: These results show that RIRS is an efficient and safe method in elderly male patients with kidney stones. Well-designedstudies with large scales are required for the confirmation of this study.
