The possibilities of modern flexible ureteroscopes in the treatment of complex forms of urolithiasis and the achievement of "stone free”
The article represents three complex clinical cases describing the use of flexible ureteroscopes in patients with urolithiasis. The features of the use of flexible single-use ureteroscopes for percutaneous nephrolithotripsy, retrograde intrarenal surgery and antegrade ureterolithotripsy are demonstrated. The treatment of urolithiasis using flexible ureteroscopes is feasible and effective method. The need of further research and development of this technique is warranted.
