Differences Between Ureteroscopy And Ureteroscopy in The Treatment Of Ureteral Diseases

① Ureteroscopy can reach the stones in the middle and lower segment, but it may not be able to reach the stones in the middle and upper segment, and it cannot pass through some physiologically curved pipes;
② Ureteral soft mirror can follow the patient's ureter, through the curved pipe, the lens can change direction at any time, it is easier to reach the upper end of the ureter.
Flexible ureteroscope is a commonly used method for the treatment of kidney stones and upper ureteral stones, which has the advantages of minimally invasive, small damage and repeated operation.

However, ureteral soft scope has adverse factors, such as the high cost of ureteral soft scope, soft mirror is relatively fragile, the operation should be careful and pay attention. The stone size is directly related to the operation time of the soft mirror. For kidney stones with a diameter of >2cm, the lithotomy time is longer, and the lithotomy efficiency is lower. For the subrenal calices, the soft mirror may have a blind area, resulting in difficulty in operation.

It is not that soft mirrors are necessarily better than hard mirrors, in special circumstances, two different endoscopes have special uses.
