The most common pathology of the kidney and upper urinary tract includes
nephrolithiasis, ureteral
strictures and renal
cysts. In the treatment of patients with these diseases, the majority of surgeons prefer minimally invasive techniques, including endoscopic surgery. The complication rate of percutaneous surgery is a major factor in encouraging the search for new treatments. We have analyzed the results of 402 x-ray-endoscopic operations performed with the use of technologies based on
titanium nickelide materials in patients with
nephrolithiasis, ureteral
strictures and kidney
cysts. The high effectiveness and reliability of porous
titanium nickelide cryoapplicator was noted in control of percutaneous channel
bleeding and prevention. The proposed
suspension nephropexy with fine
titanium granules in coexisting
nephrolithiasis and nephroptosis demonstrated 1.5 times greater effectiveness compared to the traditional nephropexy, reducing duration of
nephrostomy and rehabilitation by almost 3 times. The proposed methods of intubation by permanent and temporary
stents with shape memory after percutaneous ureteropelvic junction
stricture correction are promising in the treatment of patients with this pathology of the upper urinary tract. Application of
titanium nickelide implants in simple renal
cyst surgery has led to a significant increase in the effectiveness of these operations, improvement in long-term results and patients' quality of life.
