Introduction. This study was aimed at dynamic evaluation of lower urinary tract symptoms (LUTS) after endoscopic surgery for benign prostatic hyperplasia (BPH) depending on prostate volume.

Introduction: Perspectives and possibilities of urolithiasis surgical treatment have greatly increased during the last years.

Aim: A comparative evaluation of efficacy of standard percutaneous nephrolithotripsy and mini-nephrolitholapaxy in patients with large (up to 2,5 - 3 cm) renal and ureteral stones.

Introduction. Percutaneuos nephrolithotripsy (PNL) is mostly performed through the lower calyceal access, but in a distinct group of patients upper calyceal access is indicated. Our study was aimed at comparing results of PNL performed with different access.

Purpose. A comparative assessment of health-related quality of life in patients undergoing simultaneous bilateral and staged bilateral mini-percutaneous nephrolithotomy was conducted, and factors affecting the quality of life of patients were investigated.

Relevance: Modern minimally invasive methods of treatment of nephrolithiasis can improve the effectiveness of treatment with a significant reduction in the trauma of surgical interventions and the frequency of complications. Currently, the "gold standard " treatment of large (more than 2 cm) kidney stones is percutaneous nephrolithotomy (PCNL). One of the key criteria for evaluating the effectiveness is "SFR" (Stone Free Rate – the frequency of complete release of the kidney from stones).

Introduction. Urolithiasis is one of the most common diseases in urology. The percentage of incidence varies greatly in the world: from 1-5% to 13-20%. Extracorporeal lithotripsy (EL) does not cure the disease and the frequency of kidney stone recurrence reaches 15-80%

The aim of our study was to assess the efficacy of the phytodrug Canephron N use in the early and long-term complex metaphylaxis of urolithiasis after EL.

Introduction. Chemical composition of the urinary stone, that is, of its metabolic type, are of great importance for the choice of both invasive methods of treatment of urolithiasis and methods of stone recurrence prevention. However, urinary stones are not always available for analysis, which makes it difficult to select the best treatment methods and leads us to the need to find methods for assessing the chemical composition of patient urinary stones in a patient in vivo.

Introduction. The article presents the results of micropercutaneous nephrolithotripsy (Micro-PNLT) application in the large stonestreatment. This method was first described by M.R. Desai in 2011, and since then the MicroPNLT potential in the urolithiasis treatment is actively discussed in the medical literature. The Micro-PNLT kit was registered for use on the territory of the Russian Federation in 2018.

Aim: of our study was to compare the safety and efficiency of percutaneous nephrolithotripsy (PNL)in patientswith positive urine culture results butwithout the symptoms of urinary tract infection (UTI), and to determine the optimal duration of preoperative antibiotic therapy in this group of patients.
