Robot-assisted partial cystectomy of a bladder pheochromocytoma

Pheochromocytoma of the urinary bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We report here an unusual case of bladder pheochromocytoma that was treated by robotic-assisted laparoscopic partial cystectomy. A 35-year-old male patient presented with headache and hypertension related to micturition. The patient, who had a 3.5 × 4 cm solitary bladder tumor in the bladder dome, underwent robot-assisted partial cystectomy. The whole procedure was successfully performed using the robot without conversion to open surgery. The total operative time was 120 min and the estimated blood loss was 30 ml.
