Background: Enterovesical fistula is an abnormal communication between the gastrointestinal tract and urinary bladder. It can be due to varied etiologies including benign, malignant, trauma or iatrogenic. Cross-sectional imaging is an excellent method for detection, type, location, and etiology of fistula. Case Report: We hereby present a rare case of iatrogenic ileo-vesical fistula in a middle aged female after cystoscopic removal of urinary bladder calculus in untrained hands. Conclusion: Radiologists should be aware of this entity and keep iatrogenic injury as a possible cause of the fistula in presence of previous surgical history and if no other underlying obvious cause is present.
