Machynová S, Fedorko M, Vít V. The results of percutaneous nephrostomy tube placement under ultrasound guidance. Goal: We would like to present the experiences of our department with nephrostomy tube placement under ultrasound guidance, considering the low number of articles on this topic.

Materials and Methods: In years 2018-2021, a total of 592 ultrasound-guided percutaneous nephrostomies were performed in 363 patients. The data was analyzed retrospectively. We evaluate the indications for the drainage of the upper urinary tract, the technical success rate and the number and type of complications.

Results: The most common oncological indication was the obstruction or infiltration of a ureter 284 (47,97 %); and the most common non-oncological indication was obstructive pyelonephritis 156 (26,35 %). During the observed period, the success rate was 90 %. The most frequent complication was nephrostomy drain dislodgment in 105 cases within 11 weeks after the insertion. Repeated dislodgement of percutaneous nephrostomies was significantly more common in patients with bilateral nephrostomies.

Conclusion: Percutaneous nephrostomy insertion under ultrasound guidance is a safe method for achieving upper urinary tract drainage.
