Official Title: A Multicenter Prospective Research on the Treatment of Low Pole Renal Calculus by Flexible Ureteroscope
Brief Summary: This study centers on the treatment of low pole renal stones by flexible ureteroscope and intends to find the key anatomical parameters using a prospective, randomized multi-center trial design and to make a more appropriate standard for flexible ureteroscopy of low pole renal stones.
Detailed Summary: With the development of manufacturing technique, new generation of flexible ureteroscopes have great initiative and passive bending capacity and have greatly expanded its application. In our clinical practice, we have found that IPA (Infundibulopelvic angle) is no longer a decisive factor for the success of f-URS(flexible ureteroscope) surgeries. Thus, we think it is necessary to have further study on the effect of anatomy of renal collecting system for f-URS surgeries.
Sponsor: Changhai Hospital
Current Primary Outcome: whether the f-URS could enter the low kidney calyx or not [ Time Frame: during the operation ]
Original Primary Outcome: Same as current
Current Secondary Outcome: stone clearance [ Time Frame: 4 weeks post-operatively ]
Original Secondary Outcome: Same as current
