What is percutaneous nephrolithotomy?

Clinically, if the stone in kidney is larger than 2cm, ordinary ureteroscopy is used for lithotripsy, which is easy to form postoperative stone street. Percutaneous nephroscopy is normally selected for surgical treatment. Percutaneous nephroscopy is a minimally invasive surgery in urological surgery, but it will cause damage to the kidney during the operation. Under the guidance of color Doppler ultrasound, puncture will be carried out in a relatively good renal calyx. Normally, incision will be made through the skin, and then enter the puncture kit, enter the renal interstitium through the renal cortex and medulla, and when the kit is clamped inside the kidney, laser optical fiber introduction will be carried out, and then the stone will be completely crushed under the guidance of the front camera. During the crushing process, the stones can be directly rushed out of the body, and the double J tube will be retained after the stones are divided into powder. The stones will be removed in the hospital 6-8 weeks after surgery. Normally, this situation is cured.
