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 Description:
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.
