Transurethral partial cystectomy with 2 μm thulium continuous wave laser in the treatment of bladder pheochromocytoma.

Abstract Purpose: To introduce transurethal partial cystectomy with a 2013 nm thulium laser as a treatment for paraganglioma of the urinary bladder in adults. Patients and Methods: Three patients with pheochromocytomas were treated transurethrally with a 2013 nm thulium laser under general anesthesia. A 2013 nm thulium laser was used to incise the full-thickness bladder wall around the tumors. The entire bladder wall was peeled between the detrusor muscle layer and outer connective tissues. Tumors with full-thickness detrusor muscle layers at the base were removed together. Intraoperative fluctuation of blood pressure, preoperative values of 24-hour urine catecholamine (CA) and vanillylmandelic acid (VMA), and postoperative complications were observed, and postoperative followtwoups were performed. Results: All operations were successful. Operative time was 25 to 32 minutes. Perioperative blood pressure was stable in two cases while blood pressure fluctuated in the third case. When the entire tumor and th...
