[STANDARD TRANSCUTANEOUS AND ULTRA-MINI TRANSCUTANEOUS NEPHROLITHOTRIPSY IN TREATMENT OF NEPHROLITHIASIS].

Comparative analysis of two variants of transcutaneous nephrolithotripsy (TCNLT) in 45 patients, suffering nephrolithiasis, was performed. In 17 patients (the first group) the ultra-mini (UM) TCNLT, using tubus 11Сh, was done, and in 28 patients (the second group) – TCNLT, using a standard tubus 24Сh. The operation duration in the first group have had constituted (86.2 ± 16.3) min at average, and in the second group – (51 ± 13.6) min. The method of UМ TCNLT is a secure, miniinvasive, owing low rate of morbidity, comparing with a standard procedure, but with equal efficacy, concerning the «stone free» status (accordingly, 95.3 and 96.5%) in patients when calculi’s diameter up to 2 sm. Тubus 11Ch guarantees lesser risk of hemorrhagic complications occurrence, permits to conduct UM TCNLT without nephrostomic draining of the renal calyx and pelvis system more confidently.
