Do ulcerative and nonulcerative forms of bladder pain syndrome/interstitial cystitis differ in symptom intensity or response to onabotulinum toxin A?
In this cohort, Ulc and NUlc patients had similar symptoms at baseline and comparable clinical response to intratrigonal OnabotA. These findings suggest that pain may not be directly related with ulcers themselves.
Coil embolization of the GDA may induce arterial hepato-intestinal collaterals. Although most of these collaterals do not impede (90)Y administration, SIRT may become unfeasible in specific occasions. Hence, segmental or lobar SIRT instead of a whole-liver approach with coiling of the GDA is recommended.
