[Decompression of upper urinary tract in various pathological conditions].

Obstruction of the upper urinary tract (UUT) is a heterogeneous clinical case, which, if necessary or in case of complications, is relieved by percutaneous nephrostomy or ureteral JJ-stent placement, which have its "pros and cons" in relation to complications, costs, difficulties in performing various pathological conditions, quality of life of patients and further treatment. The European Association of Urology Guidelines on Urolithiasis 2024 are based on the 2010s data review., fourteen years later, the optimal method of UUT decompression in various pathological conditions remains under debate. In this lecture we present methods, indications, contraindications, complications, quality of life of patients under various methods of UUT draining, as well as the benefits of ureteral stenting and percutaneous nephrostomy.
