Depending on stone type, the risk of a recurrence makes 50-80%, when performing postoperative prevention this risk decreases to 10-15%. Frequent development of a relapses of infectious kidney stones after PCNL, uropathogens revealed a difference in the urine and kidney stones need to find new modes of antimicrobial prophylaxis of recurrences of infectious genesis stones.

The aim of the study is to reduce number of a recurrence of stones of an infectious genesis after a percutaneous nephrolithotripsy.

Introduction. Percutaneous nephrolithotomy is considered as the gold standard in the treatment of patients with full staghorn kidney stones. Its effectiveness varies from 55% to 98%, which depends on many factors, and in particular, on the accessibility to the stones.

The aim of the study was to analyze out own experience of performing PCNL in patients with staghorn kidney stones (stages K3-K4).

Nowadays percutaneous nephrolitothripsy (PCNL) is a standard therapeutic modality for large and staghorn kidney stones. Given that nephrostomy drainages could be a cause for pain and substantial discomfort, tubeless PCNL is considered to be a good alternative approach. The aim of our study was to evaluate the efficacy and safety of hemostatic matrix in patients with tubeless PCNL. 

The actuality of this study is defined by the lack of knowledge in the area of treatment of large or staghorn stones of solitary kidney. 

Introduction. Analysis of the – experience with large and staghorn stones of the solitary kidney was carried out to optimize the treatment of this group of patients.

In this article we present our experience and analysis of periand postoperative complications after percutaneous nephrolithtomy (PCNL) in patients with large and staghorn kidney stones. In period from 2009 up to 2013 we have performed 1649 PCNLs with a growth tendency of 36% pro year.

Ureteral peristalsis and pelvic pressure were studied in the patients with kidney stones, which were treated by means of percutaneous nephrolithotripsy (PCNL). Besides the common urological investigations the peristalsis status of the upper, middle and lower thirds of the ureter was evaluated with the use of the multichannel impedance uretrography in 12 patients immediately before the PCNL.

Operative treatment in patients with large and staghorn urinary stones of anatomically or functional solitary kidney is one of the complicated problems in urology. Literature review shows that extracorporeal shockwave lithotripsy (ESWL) as monotherapy has low efficacy in patients with this form of urolithiasis and its role could be described as amplification of other modalities, for example, in the combination treatment with transurethral and percutaneous manipulations.

Percutaneous nephrolithotripsy (PCNL) became a standard for the large and staghorn stones of the kidney, forcing out the open surgery. Today the standard PCNL is being compared in terms of efficacy to the technique using the instrument with smaller diameter. The desire to use the smallest possible access stems from the necessity to reduce the intra- and postoperative complications.

According to the recommendations of the European and American urological associations percutaneous nephrolithotripsy (PCNL) stands ahead of the other operative modalities in treatment of the patients with large and staghorn stones with the efficacy of approximately 80%. Aim of the current investigation was to estimate the influence of the body mass index (BMI) on the efficacy of the PCNL and on the frequency of the complications during the retrospective analysis of our surgical data.
