BACKGROUND: @entity6369 ( @entity6369 ) is one of the most common @entity260 associated with @entity2463 ( @entity2463 ) correction. OBJECTIVE: To describe our MRI protocol for evaluating acquired @entity6369 following @entity2463 surgery, and associated imaging findings. MATERIALS AND METHODS: Two radiologists retrospectively reviewed 61 pelvic MRI examinations performed for postoperative @entity2463 for @entity6369 identification and characteristics. Associated clinical, operative and cystoscopy reports were also reviewed and compared to MRI. RESULTS: An abnormal retrourethral focus suspicious for @entity6369 was identified at MRI in 13 @entity1 . Ten of these @entity1 underwent subsequent surgery or cystoscopy, and @entity6369 was confirmed in five. All of the confirmed @entity6369 cases appeared as @entity5409 that were at least 1 cm in diameter in two imaging planes. Four of the false-positive cases were punctate retrourethral foci that were visible only on a single MRI plane. One @entity1 had a seminal vesical cyst mimicking a @entity6369 . CONCLUSION: Pelvic MRI can be a useful tool in the postoperative assessment of suspected @entity6369 associated with @entity2463 . Radiologists should have a high clinical suspicion for a postoperative @entity6369 when a cystic lesion posterior to the bladder/posterior urethra is encountered on two imaging planes in these @entity1 .
