What Causes Difficulty In Urination Post Enema Procedure?

hello, i recently had a barium enema exam performed through my rectum. After the exam i noticed that i have difficulty urinating. I can urinate. However, i don t feel the need to go and when i do use the bathroom theres not much urine. i was wondering if this is normal. I have a history of vesicovaginal fistula so i am very worried that the repair has failed. Before the exam everything was great.
