Overview
Brief Summary
The aim of this trial is to compare the safety, efficacy and cost effectiveness of the three types of scopes.
Detailed Description
With the advancement of technology, flexible ureteroscopy (f-URS) has become an attractive option for surgical management of kidney stones. However, the durability of flexible ureteroscope still remains a major concern. Due to the high cost and limited durability, the cost-benefit of non-disposable flexible ureteroscope continues to be the most important factor for initiating and maintaining fURS programs worldwide, especially in the developing countries. Nowadays, disposable digital flexible ureteroscopes are available, offering an improved image resolution, no need for sterilization and repair, and more economic.
