COMPARATIVE CHARACTERISTICS OF THE EFFECTIVENESS OF MINIMALLY INVASIVE PERCUTANEOUS NEPHROLITHOTRIPSY (MIP) AND TRADITIONAL PERCUTANEOUS NEPHROLITHOTRIPSY WITH KIDNEY STONES FROM 2 TO 3 CM IN SIZE

The study comparatively analyses patients with a single kidney stone from 2 to 3 cm in size after percutaneous nephrolithotripsy (PCNL) and minimally invasive percutaneous nephrolithotripsy (MIP) on the basis of the urology clinic of the First Moscow State Medical University n.a. I.M. Sechenov.The investigation included 55, 27 of them underwent PCNL surgery, and 28 - MIP. We evaluated operation time, the rate of destruction and evacuation of the stone, reduction of the hemoglobin level, the procedure for completing the operation, postoperative hospital stay and intra- and postoperative complications.Mean duration time of MIP was 47.5 min, PCNL - 60 min. The rate of destruction and evacuation of the stone at MIP was 75.2 mm3 / min, and at PCNL - 157.5 mm3 / min. At MIP, the level of hemoglobin decrease was 2.11±1.1 g / l, at PCNL 7.7±1.6 g / l. At MIP, the non-infective operation termination was applied in 32.1%, at PCNL - not applied. Nephrostomy at PCNL - 85,7%, at MIP - 66,7%. At MIP the average duration of postoperative hospital stay was 5 days, at PCNL - 7 days. Thus, MIP is an effective and safe technique for a solitary kidney stone from 2 to 3 cm in size and can replace conventional PCNL.
