Cyanoacrylate Glue Masquerading as an Obstructive Calculus: Rare Sequelae of Angioembolization for Renal Pseudoaneurysm

Renal pseudoaneurysm is a well-known albeit rare vascular complication following renal trauma, percutaneous interventions, renal biopsy, and partial nephrectomy. Angioembolization has become an effective treatment option for pseudoaneurysm using Cyanoacrylate glue, Gel-foams, Micro-coils, polyvinyl alcohol, etc. We herein present a 20-year-old gentleman with infected left hydroureteronephrosis secondary to an impacted foreign body in a ureter, specifically, down-migrated cyanoacrylate glue. This is two weeks following glue angioembolization for a left upper polar segmental renal artery pseudoaneurysm secondary to stab injury. He underwent a successful left-side ureteroscopic extraction of this polymerized glue, following which his symptoms subsided. These complications of glue migration following angioembolization are infrequent, and reports of it are scarce in the literature. Stringent follow-up and timely intervention are essential to mitigate disastrous outcomes.
