Introduction and Objective: Percutaneous Nephrostomy (NP) is a
procedure that involves the placement of a drainage catheter in the
renal pelvis by puncture through the skin guided by an imaging method.
The objective of the work is to present our experience in PN with
ultrasound guidance (zero irradiation) in patients with ureteral
obstruction secondary to oncological pathologies, showing the
step-by-step technique and the usefulness of the 7 French central venous
catheter set (CVC-7F).
