Retrograde or endoscopic approach of Double-J stent (DJS) is still the most favorable choice of treatment in both benign and malignant ureteral obstruction. Percutaneous nephrostomy (PCN) is, however, an alternative to DJS placement. Antegrade placement of DJS (either plastic or metallic) can be done easily with no particularly significant complication when the PCN tube is already placed in the kidney. The metallic DJS or Resonance® stent is probably preferable to the plastic DJS in terms of median life span and cost effectiveness. We report on cases with the use of metallic DJS or Resonance® stent in patients with failed placement of the DJS via either a retrograde or endoscopic route. We summarize the demographic data of four (4) cases of antegrade placement of metallic DJS.
