Percutaneous nephrostomy versus antegrade double-J stent placement in the treatment of malignant obstructive uropathy: a cost-effectiveness analysis from the perspective of the Brazilian public health care system.

Objective: To compare two percutaneous techniques used in the treatment of malignant obstructive uropathy-antegrade double-J stent placement (JJ stenting) and percutaneous nephrostomy-in terms of their cost-effectiveness, from the perspective of the Brazilian public health care system.

Materials And Methods: In this cost-effectiveness analysis, we employed decision-analytic modeling. We calculated material costs from 2017 factory prices listed by the Brazilian Pharmaceutical Market Regulatory Board (for medications) and published in the journal Revista Simpro (for medical devices).
