“…8 In RIRS, this tool is used to provide access to the ureter, to define the renal collection system, to reach the stone, and to insert stents and guidewires. 9,10 In diagnosis and treatment of urinary stones, the use of fluoroscopy has become widespread, and thus patients and surgical team were exposed to higher amounts of radiation. 11 The amount of exposed radiation depends on many factors such as the procedure performed, equipment at hand, and the technique used.…”

were prospectively evaluated. Patients with ureteral Double-J (DJ) inserted for dilatation, with anatomical anomalies, and who had previously undergone stone surgery, were excluded. A total of 62 patients, who were operated with this new method without using fluoroscopy, were included in the study.All patients were informed about the procedure. Urinalysis and urine culture were performed. Patients who had a culture with growth were administered appropriate antibiotherapy, and the patients with sterile urine samples were then taken to the operation. Kidney Ureter-Bladder (KUB) study was ordered on the postoperative first day, and ultrasonography (USG) was

“…The majority of these studies have stated that as the stone size increased, the success of the surgery decreased. Also, they found that rising stone size could increase the possibility of residual stones [21-23]. Contrary to other studies, Ho et al [24] found that stone size did not affect SFR in their study.…”

“…In studies evaluating the efficiency of RIRS in lower pole stones, it was shown that the presence of lower calyx stones significantly reduces SFR [25, 26]. On the other hand, contrary to these data, a study showed that there was no relation between stone localization and SFR [21]. Similarly, Martin et al [27] and Ho et al [24], in their study, stated that RIRS had a similar efficiency in lower pole stones and other stones.…”

Introduction: The primary aim of this study is to compare the efficacy and safety of retrograde intrarenal surgery (RIRS) among the children and adults with similar stone burdens and locations. Also, the secondary aim of this study is to identify the factors affecting the stone-free rates (SFRs) of RIRS. Methods: We retrospectively compared perioperative results, SFRs, and complication rates (CRs) between pediatric (group 1, n: 55) and adult (group 2, n: 220) age groups diagnosed with kidney stones and treated by flexible ureterorenoscopy using the same instruments. Furthermore, multivariate analysis was performed to determine the factors affecting the SFR. Results: A total of 275 patients (pediatric group: 55; adult group: 220) were included in this study. The mean age of pediatric and adult groups was 7.2 ± 5.3 and 43.9 ± 15.1, respectively. The mean stone size was 13.9 ± 6.6 mm in the pediatric group compared to 14.8 ± 6.7 mm in the adult group (p = 0.35). Stone localizations and number were similar. JJ stenting for passive dilatation and use of UAS were higher in the pediatric group (p = 0.002; p = 0.017). However, postoperative double pigtail stenting rate was higher in the adult group (p < 0.001). Total CR was 13.8% and mostly Clavien I–II, and no difference was observed between the 2 groups (p = 0.541). The SFRs between the groups were similar (pediatric group: 81.8%; adult group: 78.2%; p = 0.554). On multivariate analysis, stone size (p < 0.001) and lower calyx stone (p < 0.001) were the negative predictive factors for SFR. Conclusion: There are small technical differences between pediatric patients and adult patients in our study, but RIRS in children is as safe and efficient as it is in adults.

“…[11] Stone size and/or volume have/has been reported to significantly affect SFR in RIRS. [12,13] Goldberg et al [12] reported a significantly lower SFR (85%) in renal stones >15 mm. The mean preoperative time, hospital stay and complication rate were also higher in patients with renal stones larger than 15 mm.…”

The “old” 15 mm renal stone size limit for RIRS remains a clinically significant threshold size

Abstract: While the overall SFR following RIRS for renal stones up to 2 cm is generally high, the SFR for 15-20 mm stones is significantly lower, with a longer operating time and hospital stay, and a higher complication rate.
