Kidney stones are a common disease and cause many dangerous complications. The disease is more common in people between 40 and 70 years of age. Percutaneous renal lithotripsy is one of the methods to treat kidney stones with a size > 1.5cm
1. Treatment methods for kidney stones
Kidney stones are one of the most common urinary tract diseases. Kidney stones form due to the deposition and crystallization of minerals present in the urine. There are many causes of kidney stones, the most common of which are unhealthy eating habits, lack of exercise and poor water habits. Depending on the time of formation, location and degree of sedimentation, kidney stones will have different sizes.
Kidney stones account for half of all urinary tract diseases. Kidney stones, if not treated properly, can lead to serious complications such as pus, fluid retention, infection, kidney failure and even death.
For cases of kidney stones that do not cause urinary tract dilatation complications, the patient can take medicine as prescribed by the doctor. The doctor can prescribe some drugs to dissolve the stones that contain urate or cystine..
If the stone is larger, the patient needs to be treated with surgical measures. Currently, kidney stones can be treated by the following methods:
Standard endoscopic percutaneous lithotripsy (Standard PCNL) This is a highly effective method, limiting invasiveness. This method can completely replace open surgery for all stones > 25mm, especially "coral" stones. Patients will be under general anesthesia, less trauma to the end, less pain, surgery scar < 1 cm, short hospital stay.
Endoscopic minimally percutaneous lithotripsy (Mini PCNL) Minimally percutaneous endoscopic lithotripsy is very effective in cases of stones from 15-25 mm, ureteroscopy or lithotripsy has failed. .
Ureteroscopy The doctor will use a very small ureteroscope to pass through the urinary opening, up the ureter to access the stone. The doctor will then use a laser to break up the kidney stone. The stones will be sucked out with a ureteroscope. The ureteroscopy method does not cause scarring, reduces pain and shortens the hospital stay.
Extracorporeal lithotripsy (ESWL) This method is applicable for stones <15mm. The doctor will use shock waves to break up the stone. The fragments of the stone will be expelled with the urine. The lithotripsy method is effective from 55 to 85% and the hospital stay is only 1⁄2 days.
