[Internal urinary derivation using an antegrade approach: indications, technic and results]

Area of Science:

• Urology
• Interventional Radiology

Context:

• Ureteral obstruction presents a significant clinical challenge.
• Traditional retrograde double J stent placement can be difficult or impossible in cases of severe obstruction.

Purpose:

• To evaluate the efficacy and outcomes of fluoroscopy-guided percutaneous double J stent placement.
• To discuss the indications, techniques, and results of this interventional approach for ureteral obstruction.

Summary:

• A cohort of patients with diverse pathologies causing ureteral obstruction were treated.
• Percutaneous fluoroscopic guidance was employed when retrograde stent insertion was unsuccessful.
• The study details the specific reasons for failure, the procedural steps, and the clinical outcomes.

Impact:

• This technique provides a crucial alternative for managing complex ureteral obstructions.
• Successful stent placement facilitates urinary drainage and alleviates patient symptoms.
• Offers valuable insights for urologists and interventional radiologists facing challenging stent placements.
