[A case of bladder paraganglioma managed by transurethral approach, using holmium laser]

A 78-year-old man was referred to our hospital with a bladder tumor. He suffered from headaches and palpitations after voiding. Cystoscopy and MRI showed a submucosal bladder tumor which localized submucosally without invasion to the muscular layer. The tumor was positive for 131I-MIBG scintigraphy and we diagnosed it as a bladder paraganglioma. We enucleated the tumor en bloc from the bladder using holmium laser via transurethral approach, with minimal alteration of blood pressure during the procedure. The enucleated tumor was evacuated out of the bladder with a morcellator.
