Needle nephrolithotripsy is often referred to as percutaneous nephrolithotripsy. Needle nephrolithotripsy has a thin outer diameter and a small operating space, and is only suitable for a small number of patients who require nephrolithotripsy with a small stone load.
The main method of percutaneous nephrolithotomy is to use a fine needle to puncture from the back of the waist directly to the renal pelvis or calyx under the localization of imaging such as ultrasound or X-ray, so as to dilate and establish an external channel from the skin to the kidney, and then carry out a series of stone extraction or lithotripsy operations under the nephrolithoscope.
Percutaneous nephrolithotomy is suitable for most of the renal stones that require surgical intervention, including renal stones under 2cm that are ineffective in extracorporeal lithotripsy or accompanied by obvious hydronephrosis, and renal stones larger than or equal to 2cm in size. It is important to note that this procedure is contraindicated for people with blood clotting disorders; people who are too obese for the puncture needle to reach the kidney; and people with spinal deformities.
If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
