| Popis: | To evaluate the safety and efficacy of ureteral occlusion stents for urinary diversion in patients with inoperable urinary leakage or fistula or intractable bladder bleeding. A total of 13 ureters in 12 patients (M:F = 4:8) who underwent ureteral occlusion stenting were included in this study. The internally silicone membrane-coated occlusion stent was a self-expanding stent with constriction at the middle (M-type) or distal end (D-type) of the stent. The reasons for ureteral occlusion were surgery infeasibility for urinary leakage (n = 6), temporary ureteral occlusion for urinary leakage before surgical reconstruction (n = 2), urinary fistula (n = 3), or control of bleeding from bladder cancer (n = 1). Technical success defined as successful deployment of the occlusion stent with no contrast agent passing beyond the occlusion stent was achieved in 92.3% (12/13 ureters); in one ureter with contrast passage beyond the occlusion stent, additional n-butyl cyanoacrylate (NBCA) embolization was performed immediately so that there was no further leakage. There were no procedure-related complications. During the mean follow-up of 11.6 months, recurrence of urinary leakage was observed in two ureters (15.4%, 2/13) where a D-type occlusion stent was used on the 3-day follow-up antegrade ureterogram; the contrast agent passed through the widened constricted portion of the occlusion stent and repeat occlusion with microcoils, and NBCA was subsequently performed inside the occlusion stent and with no further urinary leakage until the last follow-up. The ureteral occlusion stent is safe and effective for ureteral occlusion. Recurrence of leakage can be managed with additional microcoil and NBCA embolization. |
