Holmium laser lithotripsy

Holmium laser is a pulsed laser with a wavelength of 2.1 μ m, which has strong safety and wide applicability compared with the commonly used extracorporeal shock wave lithotripsy and pneumatic ballistic lithotripsy. In the process of lithotripsy, stones rarely run, and the return rate is very low, so the efficiency is greatly improved. It can be directly crushed through cystoscopy, ureteroscopy and percutaneous nephroscopy, without causing tissue damage. And the holmium laser fiber is flexible, so it can effectively treat the ureteric stones and kidney stones in any site.

The study shows that the single success rate of endoscopic holmium laser lithotripsy is more than 95%, and the treatment of bladder stones can reach 100%. The procedure is non-invasive or minimally invasive, and the patient is basically painless. There is no risk of perforation, bleeding, but also the combined treatment of urinary tract tumor, ureteral polyps, stricture and so on.

What is the procedure of holmium laser lithotripsy?

The specific process is soft ureteroscopic holmium laser lithotripsy is to use a fiber optic lens with about 3mm in diameter, inserted into the ureter through the urethra and bladder to the renal pelvis and calyx. Holmium laser fiber is used to remove and drain the upper ureteral stones and kidney stones. The use of human natural urinary tract, without making any incision in the body, is a pure urology cavity minimally invasive technique, so it is favored by patients.

What are the advantages of holmium laser lithotripsy?

1. Precision and efficiency. The target, energy and action time of holmium laser pulse are accurately positioned and quantified by computer, which can be solved once in a relatively short time. The whole process of accurate control, physician intuitive image surgery, safe and efficient.

2. Less trauma and safe. Holmium laser only acts on stones and does not have a thermal effect on the surrounding tissues, so in the process of lithotripsy, it will not cause any loss to the surrounding tissues, and there is no risk of perforation, bleeding and some complications caused by traditional surgery.

3. Fast speed and short treatment time. This laser has a strong adsorption of water, so that the laser energy is concentrated in the surface layer, has a good cutting ability and tissue resection ability, so that the gravel particles more fine, powder, so the stone time of the gravel is significantly shortened.

4. Less complications and more money. After the successful treatment of urocalculi with holmium laser, the patients had no sequelae, few complications, completely avoided many complications of traditional surgery, caused the disadvantages of secondary injury to the body tissue, greatly shortened the treatment time of patients, and reduced the cost accordingly.
