Hexylaminolevulinate (hexa ALA) "blue light" fluorescence for detecting cellular changes in mucosal epithelium is used in urology to detect transitional-cell carcinoma and carcinoma in situ in the bladder. It is is also being studied for the detection of precancerous/cancerous lesions in the colon. We present a case in which hexa ALA fluorescence cystoscopy was used in the evaluation of cecal mucosa that was incorporated into the bladder as an augmentation cystoplasty. To our knowledge, this is the first time the imaging appearance of an augmented bladder under Hexa ALA fluorescence cystoscopy is described.
