[Prevention of bleeding during tubeless percutaneous nephrolithotomy].

Introduction: Nephrostomy tube placed after percutaneous removal of kidney stones can cause pain and discomfort in the early postoperative period [1, 2]. A tubeless percutaneous nephrolithotomy (PCNL) is considered as alternative approach. However, the most serious complication after tubeless procedure is a development of active uncontrolled bleeding from percutaneous tract in the early postoperative period.

[Multi-tract percutaneous nephrolithotomy in the management of staghorn stones].

Aim: To compare the results of a single tract versus multi-tract percutaneous nephrolithotomy (PNL) MATERIALS AND METHODS: Over a period of 6 years, a total of 2,264 PNLs was performed at the N.A. Lopatkin Scientific Research Institute of Urology and Interventional Radiology, of which 875 PNLs were done for stage K3-K4 staghorn calculi.

[Analysis of clinical effectiveness and risk factors for complication of percutaneous nephrolototripsia in patients with a solitary kidney].

Relevance: Management of patients with large and staghorn stones of a solitary kidney is widely debated among urologists and has not been sufficiently investigated, which determined the relevance of this study.

Materials And Methods: The study comprised 80 patients with large (>20 mm) and staghorn stones of an anatomically or functionally solitary kidney. Of them, 58 patients underwent percutaneous nephrolithotripsy (PNL), and 22 had open surgery.
