Minimally invasive procedures for kidney stones include percutaneous nephrolithotripsy lithotripsy, rigid ureteroscopy and flexible ureteroscopy lithotripsy treatments, which are minimally invasive procedures that generally have little impact on the kidneys. Patients with kidney stones can be treated with percutaneous nephrolithotripsy, a procedure that involves making a hole in the kidney area and then entering the renal pelvis to break up the kidney stones under the nephroscope. At this time, there will be a passage of 1cm in diameter in the kidney, and part of the renal cortex of the patient will be damaged and bleed, but the damage is relatively mild and usually has little effect on renal function. If patients are treated with ureteral rigid and ureteral flexible ureteroscopic lithotripsy, sterile saline may be instilled during this minimally invasive procedure. If the amount of sterile saline instilled during the procedure is too large, it may lead to an increase in pressure in the renal pelvis, which may easily cause bleeding of the renal peritoneum or transient renal injury, but it will not affect the kidneys too much. Kidney stone patients with minimally invasive surgical treatment on the kidneys, need to timely medical treatment, the doctor will be based on the patient’s condition to determine.
