Objective To compare the safety and efficacy of oblique supine position and lithotomy position in suctioning flexible ureteroscopic lithotripsy. Methods 82 patients with upper urinary calculi were divided into two groups. Group 1 included 47 patients who were treated by suctioning flexible ureteroscopy in oblique supine position. Group 2 included 35 patients who were treated in lithotomy position. There was no significant statistical difference in age, gender and complications between the two groups before surgery (P > 0.05). The operative time, stone-free rates at postoperative 30 d, renal pelvic pressure (RPP), postoperative complications (graded by the Clavien system) and length of stay were compared. Results Retrograde Intrarenal Surgery (RIRS) was successful in 73 cases, and 9 cases of patients were done successfully after indwelling DJ tube 2 weeks. Compared with lithotomy position, a significantly greater stone-free rate of 30 d, shorter operative time (P < 0.05). There was no difference in complication rate of Clavien grade I and Clavien grade II, RPP and length of stay (P > 0.05). Conclusions Suctioning flexible ureteroscopic lithotripsy in the oblique supine position is safe, and more effective than supine lithotomy position.

Objective:
To evaluate the effectiveness and safety of intelligent pressure control flexible ureteroscope for management of renal stones ≤2 cm.
Methods:
The clinical data of 267 cases of renal calculi treated with flexible ureteroscope lithotripsy at Department of Urology, Ganzhou People′s Hospital from June 2015 to December 2017 were analyzed retrospectively. There were 129 male and 138 female patients, with a mean age of 51.2 years (ranging from 19 to 76 years). Among them, 145 patients underwent intelligent pressure control flexible ureteroscope (intelligent control group) and 122 patients underwent flexible ureteroscope ordinary (ordinary group). The
