Why do kidney stones fall into the ureter?

6cm, which is larger than the diameter of the ureter and is difficult to discharge into the ureter. Laser lithotripsy can be considered. At this time, anesthetic analgesics are needed to relieve pain. Ultrasound examination of both kidneys and ureters is required to understand the size and location of the stones. Kidney stones are generally located in the renal calyx or renal pelvis. The renal pelvis has a large space and the stones are more active. If the stone falls off, it will fall into the catheter because the renal pelvis and ureter are connected to each other. If the diameter of the kidney stone exceeds 0.

The lower ureteral stone cannot be removed

If the lower ureteral stones cannot be discharged and become incarcerated, hydronephrosis and hydroureter are also likely to occur. At this time, surgical treatment is required, and the stones can be directly crushed and discharged through a ureteroscope. Color Doppler ultrasound and CT scan of the urinary system are performed to observe the size of the stones. For smaller lower right ureteral stones, extracorporeal shock wave lithotripsy can be performed. Generally, ureteral stones, whether formed in the ureter or kidney stones falling into the ureter, are not too large, and conservative or drug treatments can be tried first, such as increasing exercise and drinking water as appropriate.

Kidney stone soft endoscopy surgery

The zebra guidewire is placed in the ureter, and then the ureteroscope is withdrawn, and then the zebra guidewire in the ureter is placed in the delivery sheath in the ureter. The sheath should be placed to a certain depth, and then the soft scope is inserted again through the delivery sheath. After insertion into the renal pelvis, the stone can be seen. The stone is broken by laser, and then the stone is flushed, the ureteroscope is pulled out, the double J tube is placed under the guidance of the guidewire, and the ureter, delivery sheath, and ureter are pulled out. The zebra guidewire is placed in the ureter, and then the ureteroscope is withdrawn, and then the zebra guidewire in the ureter is placed in the delivery sheath. The sheath should be placed to a certain depth, and then the soft scope is inserted again through the delivery sheath. After insertion into the renal pelvis, the stone can be seen. The stone is broken by laser, and then the stone is flushed away, the ureteroscope is pulled out, the double J tube is placed under the guidance of the guidewire, and the ureter is pulled out. Kidney stone soft endoscope surgery is currently a very recommended surgical method.
