Mini-PNCL vs PNCL: comparative analysis of efficiency and safety of nephrolithotripsy techniques with large single and staghorn stones

Contacts: Belousov IgorIvanovich, belrost_dept@mail.ru Introduction. Currently, there are studies that evaluate the potential of mini-percutaneous nephrolithotripsy (mini-PNL) in the treatment of kidney stones up to 2 cm in size. At the same time, there are publications that compare the effectiveness of PNL with endoscopes of various diameters with such stones. At the same time, there are practically no studies where the possibility of making large single kidney stone and staghorn stones of PNL is studied with an endoscope of small diameter in comparison with a standard size endoscope. Materials and methods. e effects of PNL 96 patients with large single kidney stone > 20 mm, and staghorn stones were investigated. Depending on the size of the instrument used, patients are separated into 2 groups.Group 1, 45 patients, operated onwith an endoscope ofstandard size, 26Ch; in group 2, 51 patients, PNL conducted with a mini-endoscope, 15Ch. In accordance with the type of stones, separation into subgroups has been introduced: large single kidney stones - subgroups 1A and 2A; staghorn stones - subgroups 1B and 2B...
