Minimally invasive partial cystectomy with bilateral vesico-ureteric junction resection and reimplantation for a large paraganglioma involving urinary bladder trigone

摘要

Paragangliomas are neuroendocrine tumours of extra adrenal origin. Although it occurs rarely in thegenitourinary system, urinary bladder is the most common site. Its diagnosis warrants complete surgicalexcision with lymphadenectomy in case of metastatic disease. The functional status of this tumourmakes intraoperative handling challenging. Surgical resection necessitates minimal manipulationof tumour thereby mitigating intraoperative physiological jeopardy. We report the possibility of minimallyinvasive partial cystectomy with bilateral vesico-ureteric junction resection and re-implantationfor non-malignant paraganglioma involving the bladder trigone. Intraoperative frozen section isdeemed necessary to achieve tumour free margin status.
