The authors report the perianesthetic considerations of a rare case of pheochromocytoma of the urinary bladder for which the first reported robotic partial cystectomy and ureteric reimplantation were performed. A 59-year-old male patient, known to be hypertensive, was posted for transurethral resection of a bladder tumor. In the operation room, after attaching the monitors, a subarachnoid block was given. Upon manipulation of the tumor, the blood pressure and heart rate increased markedly. A pheochromocytoma was suspected and was later confirmed by raised urine catecholamine levels and meta-iodobenzyl-guanidine scan. The patient was started on tablet prazosin and atenolol. After optimization, a robotic partial cystectomy was planned. In the operating room, an epidural catheter and a radial artery cannula were inserted. After the induction of anesthesia and the securing of the airway, surgery was started. After the insertion of the verres needle, pneumoperitoneum was created very slowly, and then the patient was positioned in 40° Trendelenburg. Surges in arterial blood pressure (ABP) were managed with titrated doses of sodium nitroprusside and nitroglycerine and boluses of esmolol and labetalol. ABP drops postoperatively were managed with fluid and dopamine infusion. Robotic surgery is a safe alternative to the open technique for pheochromocytoma of the urinary bladder. Care should be taken during the positioning of the patient for robot placement and during pneumoperitoneum creation.
