Objective To evaluate the safety and efficacy of bipolar plasmakinetic system in exfoliative tran-surethral resection of bladder tumors .Methods Clinical data of 72 patients with non muscle invasive bladder cancer (NMIBC) were retrospectively analyzed.Transurethral bipolar plasmakinetic system was used ,30°viewer,F27 outer sheath was pushed off and bladder tumor was cut .When the bladder filling state ,pushed off bladder mucosa distance from tumor basal 2cm,then electricity cut the exfoliative bladder tumor .When bladder half filling state electricity cut the base of the bladder muscle layer of bladder tumor .Results This group of 72 cases were successfully completed surgery,surgery time 37~93 min,without intraoperative bladder perforation ,slight obturator nerve reflex in 5 cases. The keeping intact pathologic specimens was good for pathological staging .Conclusion Exfoliative transurethral resection of bladder tumors with bipolar plasma is a safe , practical and effective way of operation , which can avoid severe obturator reflex occurred in the operation , and greatly reduce the occurrence of bladder perforation , without TURS,surgical removal of the pathological specimens is specification .
