Abstract
INTRODUCTION: Paraganglioma of the bladder is an extremely rare tumor, and special attention should be paid to elevation of blood pressure during tumor resection. CASE PRESENTATION: A 64-year-old woman presented with elevation of blood pressure during thoracic surgery. Multiparametric magnetic resonance imaging revealed a bladder tumor, and noradrenalin levels were elevated in plasma and urine. The tumor was surgically removed by en bloc transurethral resection with laparoscopic partial cystectomy of bladder tumor. The margin of the tumor was easily identified, and perioperative blood pressure was stable. There was no evidence of residual tumor, local recurrence, or distant metastasis during 2-year follow-up. CONCLUSION: To our knowledge, we report the first case of paraganglioma of the bladder resected by a minimally invasive and safe procedure: combination of en bloc transurethral resection and laparoscopic partial cystectomy.
