Embolization of post-partial nephrectomy upper calyceal-perirenal urinary fistula using onyx-34: A novel application of a (pseudo-) liquid embolic agent
Case report demonstrates embolization of a complex urinary fistula in a patient with pheochromocytoma, suggesting onyx-34 as a viable non-surgical option.
Key Points
To explore the use of onyx-34 for closing urinary fistulas following renal surgery, particularly in high-risk patients.
Described a case of a patient with a persistent urinary fistula following nephron-sparing surgery.
Embolization performed using onyx-34 via percutaneous nephrostomy access.
Patient had a history of pheochromocytoma and sigmoid adenocarcinoma.
Successful immediate closure of the urinary leak was achieved through embolization.
Demonstrated potential of onyx-34 as a minimally invasive treatment for urinary fistulas.
The case highlights the role of onyx-34 in patients with contraindications to surgical interventions.
