RÉSUMÉ
【Objective】 To explore the safety and efficacy of flexible ureteroscope in the treatment of upper and middle ureteral calculi complicated with lower ureteral stricture after the failure of rigid ureteroscopy. 【Methods】 Clinical data of 36 patients with middle and upper ureteral calculi and lower ureteral stricture treated with rigid ureteroscopy but failed during Oct.2019 and Oct.2021 were retrospectively analyzed. The patients’ average age was (46.2±13.2) years, and the maximum diameter of calculi was (1.3±0.3) cm. The intraoperative, postoperative and follow-up data were recorded. 【Results】 All 36 patients successfully completed first-stage operation. Intraoperatively, the stenosis degree was F6-8 and could be dilated to F9-11. The mean length of stenosis was (1.1±0.34) cm. No serious postoperative complications such as infection or bleeding occurred. Two patients were lost and 34 patients were followed up. There was no obvious hydronephrosis on ultrasound examination. The stone removal rates were 76.5%, 88.2% and 97.1%, respectively, in months 1, 2 and 3 after operation. One patient with residual stones underwent secondary ureteroscopy in month 3 and large stones were removed with stone removal basket. 【Conclusion】 In patients with middle and upper ureteral calculi and lower ureteral stricture, after the failure of rigid ureteroscopy, flexible ureteroscope is safe and effective, and can significantly increase the success rate of first-stage surgery.

Objective To explore and analyze the efficacy of laparoscopic ureterolithotomy combined with flexible ureteroscopy for treatment of middle and upper ureteral calculi with ipsilateral kidney calculi. Methods All 64 cases who were diagnosed with middle and upper ureteral calculi with ipsilateral kidney stones in our hospital from October 2010 to October 2013 were chosen as the research subjects. All of the clinical data were analyzed retrospectively. Pa-tients were divided into observation group(33 cases) who were treated with laparoscopic ureterolithotomy combined with flexible ureteroscopy and the control group (31 cases) who were treated with traditional open surgery randomly. The short-term clinical effects between two groups were compared after 8 months. Results The surgical bleeding,opera-tion time,hospital stays and the recovery time of observation group were all lower than those of control group(P<0.05). The body mass and Karnofsky scores after surgery of two groups were all higher than those before surgery. Quality of life of the observation group was better than that of the control group(P<0.05). The complications rate of the observation group was lower than that of the control group(P<0.05). Conclusion Laparoscopic ureterolithotomy combined with flexible ureteroscopy for treatment of middle and upper ureteral calculi with ipsilateral kidney stones has such advan-tages as better efficacy,smaller trauma,faster postoperative recovery,higher stone clearance rate,fewer adverse reac-tions and higher quality of life compared with traditional open surgery. It is worthy of promotion.

Objective To evaluate the efficacy and safety of double-J stents in extracorporeal shock wave lithotripsy for the treatment of middle and upper ureteral calculi, and to explore the reasonable application of double-J stents. Methods 511 patients with middle and up-per ureteral calculi in our hospital were selected as the statistical objects. 161 patients of the catheter group were indwelled double-J stent be-fore extracorporeal lithotripsy while the other 350 patients in the no-catheter group underwent extracorporeal shock wave lithotripsy directly. The satisfaction rate of X-ray display location, gravel effect, and rate of adverse reaction were compared. Results The satisfaction rate of X-ray display location in the catheter group was higher than the no-catheter group (P=0. 025). And the gravel effect of the two groups were of statistical significance (P=0. 041). The incidence of hematuria and lower urinary tract symptoms in the catheter group was significantly high-er than that in the no-catheter group (P<0. 05). The incidence of renal colic in catheter group was lower than that in no-catheter group (P=0. 001). Conclusion Indwelling double-J stents is useful for stones display and localization, and it can improve the stone clearance rate. For ureteral stones whose diameter were less than 1 cm, double-J stents has little influence on the rate of stone clearance, but it can reduce the occurrence of severe renal colic.
