The operation time was 154-200 minutes，and the intestinal function recovered 2.4（2-3） days after the operation. No severe complication was observed perioperatively. During up to 6- month follow-up，no ileus，thrombosis，tumor recurence or metastasis were observed．ConclusionOur preliminary experience shows that gaslesslaparoscopicradical cystectomy is safe and feasible for selected patients and mayreduce the incidence of pneumoperitoneum-related complications.
