Abstract：Objective: To evaluate the surgical procedures and clinical efficacy of extraperitoneal laparoscopic cystectomy. Methods: From Jan. 2011 to Aug. 2014, a total of 6 male patients with T2 muscle-invasive bladder cancer underwent operations in our hospital. The age ranged from 54 to 80 years old with a mean of 71.6. After the extraperitoneal space was built, laparoscopic cystectomy was performed by referring to the open approach. Three cases were subjected to cutaneous ureterostomy, 1 to orthotopic neobladder and 2 to ileal conduit respectively. Results: All the 6 patients were successfully operated. The operative time ranged from 120 to 200 min with a mean of 136.7 min. Estimated blood loss was 100 to 350 mL with a mean of 210 mL. The post-operative hospital stay was 7 to 16 days. All 6 patients were followed up from 3 to 18 months. The renal function of all patients was normal. No local recurrence or metastasis occurred. Conclusions: Extraperitoneal laparoscopic cystectomy is a safe and effective therapeutic method according to the initial experience and follow-up results.
