1, different curvatures: the end of flexible ureteroscope can be bent in both directions, and the curvature can reach 270. Stones can be found in renal pelvis and ureter by angle conversion, and then they are crushed by Holmium laser. For upper ureteral calculi, it is easy to cause retrograde displacement of stones during treatment, which makes rigid ureteroscopy treatment relatively difficult.

2. Different cost: The equipment cost of flexible ureteroscope is relatively high, and the operation-related cost is obviously higher than that of rigid ureteroscope.

3. The difference between endoscope and ground: Rigid endoscope is a rigid and inflexible endoscope, which is mainly used to treat ureteral space-occupying lesions and ureteral space-occupying biopsy. It is mainly used for lithotripsy of middle and lower ureteral calculi and some upper ureteral calculi. Soft mirror is a kind of flexible mirror, which is mainly used for lithotripsy of renal pelvis and calyx.

Precautions:

Ureteral calculus is a very common lithiasis, mostly single, with similar incidence on the left and right sides. It usually occurs in young and middle-aged friends and will have a great impact on normal life and health. Therefore, ureteral calculi must be treated in time.

Patients with ureteral calculi should drink more water and urinate more after operation. Increased urination can increase the amount of stones discharged from the body and recover faster.

Avoid strenuous exercise for one week, and need more exercise after one week. You can do some jumping exercises, which can promote the discharge of stones.
