Cystography (A) and axial computed tomography scan (B) 1 month after prostatectomy. Contrast agent leakage (arrows) is shown at the posterior aspect of the vesicourethral anastomotic site on the left side

One month later, the patient presented with persistent urinary leakage at the posterior aspect of the vesicourethral anastomotic site, which was confirmed by cystography (Figure 1).
Radiograph (supine position) after embolization of the contained vesicourethral fistula. The fistula was embolized with an Amplatzer vascular plug (arrow), and the urinoma cavity was embolized with N-butyl-2-cyanoacrylate (asterisk) through the JP drainage tube

The cavity seemed to have been well-obliterated (Figure 2).
Cystography 4 days after embolization. Radiographs without (A) and with (B) contrast agent injection showing the Amplatzer vascular plug (arrow, obscured by N-butyl-2-cyanoacrylate) and N-butyl-2-cyanoacrylate (arrowheads) at the anastomotic site without contrast agent leakage

Cystography carried out 4 days after embolization showed the NBCA density and AVP (obscured by overlapped NBCA) at the anastomotic site without contrast agent leakage (Figure 3).
One-year follow-up axial computed tomography (CT) scans. Serial CT scans showing stable Amplatzer vascular plug position (arrows) and complete cavity obliteration by N-butyl-2-cyanoacrylate (arrowheads)

CT scans acquired at 1-month and 1-year follow-ups showed stable AVP position and complete obliteration of the cavity by NBCA (Figure 4).
