Abstract Purpose To investigate the relationship between failure to insert a ureteral access sheath (UAS) with inflammation and other clinical parameters in patients treated with flexible ureteroscopy for renal stones. Methods This study included patients who underwent flexible ureteroscopy for the treatment of renal stones in our centre between 2015 and 2020. Patients who underwent any surgical procedure on the ipsilateral ureter and had a history of spontaneous stone passage were excluded. Patients were divided into two groups based on UAS insertion success (group 1) or failure (group 2). Both groups were compared with a view to clinical characteristics, preoperative neutrophil, lymphocyte, monocyte and platelet counts and ratios of these counts, all being considered inflammatory markers. A multivariate logistic regression analysis was performed to determine the independent variables affecting UAS insertion success. Results There were 113 (59.1%) patients in group 1, while group 2 consisted of 78 (40.9%) patients. The rates of male gender, coronary artery disease and preoperative ipsilateral hydronephrosis were significantly higher in group 2, while platelet counts and platelet-lymphocyte ratios were significantly lower. Our analysis revealed four independent predictors for UAS insertion failure: female gender (odds ratio [OR]=2.1) increased the rate of UAS insertion success, while hydronephrosis (OR=1.6), low platelet counts and PLR increased the rate of UAS insertion failure (OR=0.99, OR=0.98, respectively). Conclusion Our results suggest that male gender and ipsilateral hydronephrosis are associated with increased UAS insertion failure. Although we found a relationship between relatively low platelet levels and UAS insertion failure, we think that further studies are needed to investigate this matter.

Background: ShuoTong ureteroscopy (Sotn-ureteroscopy, ST-URS), a new lithotripsy operation method developed on the basis of ureteroscopy, is widely used to treat ureteral stones in China. Its composition includes rigid ureteral access sheath, standard mirror, lithotripsy mirror, and ShuoTong perfusion aspirator (ST-APM). Here, we compared the efficacy and safety of the ST-URS and the flexible ureteroscope (F-URS) holmium laser lithotripsy in the treatment of unilateral upper ureteral calculi.Methods: Retrospective analysis was conducted on the clinical data of 280 patients who met the inclusion 1) urinary tract CT was diagnosed with unilateral single upper ureteral calculi above the L4 lumbar spine; 2) patient age was from 18 to 80 years old; 3) patients were informed and consented to this study; and 4) patients were approved by the hospital ethics committee (proof number: KY-2019-020) and the exclusion criteria for unilateral upper ureteral calculi in the First Affiliated Hospital of Xiamen University from January 2018 to November 2020, and they were divided into the ST-URS group and the flexible ureteroscopy (F-URS) group.Results: The stone-free rate of 1 day after operation of the ST-URS group was significantly higher than the F-URS group (63.71 vs. 34.62%, P < 0.0001). The operative time (38.45 vs. 46.18 min, P = 0.005) and hospitalization cost (27,203 vs. 33,220 Yuan, P < 0.0001) of the ST-URS group were significantly lower than the F-URS group. There were no significant differences in the success rate of ureteral access sheath placement, operative blood loss, stone-free rate of 1 month after operation, postoperative complications, postoperative hospital stay, and postoperative visual analog scale (VAS) pain score between the two groups (P > 0.05). In subgroups of a diameter of calculi ≥ 1.5 cm, calculi CT numerical value ≥ 1,000 Hounsfield unit and the preoperative hydronephrosis range ≥ 3.0 cm, ST-URS shows more advantages in the operative time, stone-free rate of 1 day after the operation, the hospitalization cost, and the incidence of postoperative complications.Conclusion: In unilateral upper ureteral stones treated with a holmium laser, compared with the simple F-URS, the ST-URS has a shorter operative time, lower hospitalization cost, and a higher stone-free rate of 1 day after the operation, suggesting that the ST-URS could be more widely applied in clinics.

Background: Advancements in the endoscopic armamentarium, retrograde intrarenal surgery has become a viable and attractive option for the treatment of renal stones because of its high stone-free rates (SFRs) and low morbidity. Objective: To describe our experience and outcome of RIRS for the treatment of renal stones and to assess its effectiveness and safety. Design, setting, and participants: A retrospective analysis of 60 patients who underwent RIRS for renal stones at our institute between January 2018 to December 2018 was performed. Surgical procedure: Flexible ureteroscopy and laser lithotripsy using a standardized technique with last-generation flexible ureteroscopes (Flex-Xc) using Holmium-YAG laser. Outcome measurements and statistical analysis: Clinical data were collected and intraoperative and postoperative outcomes were assessed (Ureteral access sheath placement, operation time, hospital stay, stone free rate, post-operative blood transfusion & fever, need for second session of RIRS. A descriptive statistical analysis was performed. Results and limitations: The mean overall stone size was 13±3 mm. Pre stenting done in all cases. Ureteral access sheath placement was possible in 54(90%) patients. At 1 month follow-up, the overall primary SFR was 86.67%(52 cases), the secondary SFR was 96.67%(58 cases).The mean operative time was 91.96±18.7 min. Mean hospital stay was 1.86±1.02 days. Complications were reported in 8 (13.33%) patients overall, with fever in 6 patients (10%), steinstrasse in 2(3.33%) patients need for second session RIRS in 6 patients (10%).No patient needed blood transfusion. The main limitation of the study is the retrospective nature. Conclusions: RIRS performed using a flexible ureterorenoscope marked the beginning of a new era in urology. It is safe and effective procedure and an alternative to extracorporeal shock wave lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL) in the treatment of selected renal stones.
