Percutaneous nephrolithotripsy

When dealing with large or numerous concrements, a medical doctor requires the shortest and most direct access to the calculi. This is achieved by puncture of the kidney with subsequent expansion of the opening to the required diameter and introduction of a direct optical system of laser fiber through it. This access makes it easy to enter the renal sinuses and get the stone fragments out, if necessary. Usually, this surgery is more traumatic compared to the retrograde access, since it involves a violation of the integrity of the kidney and the patient`s body. However, the key factor in this case is a diameter to which the opening in the kidney needs to be expanded. For many years, the standard diameter of the tool for kidney access was 9 mm. In this case, an average of 3 cm3 of kidney tissue was injured. The rapid development of the laser and optical systems made it possible to reduce the diameter of the required opening to 5 mm, which decreased the volume of kidney injury to 1 cm3 and, as a consequence, ensured a much lower rate of complications. This technique was called a mini-percutaneous nephrolithotomy, and we chose it the basic for our clinic, as we believe this access method ensures the optimal safety-performance ratio in case of renal calculi greater than 2 cm. We have in our inventory the thickest – Ø 0.94 mm – laser fiber in its segment, which makes us capable of quick and efficient destruction of large calculi.

We always remember that each patient is a unique individual and the best treatment result can be obtained when a clinic has a choice of all possible most effective and least traumatic options. And that’s exactly what you get when you address the Innomed Lithotripsy Center for medical treatment.
