[Experience of laparoscopic nerve-sparing radical cystectomy and construction of ileal neobladder at Kansai Medical University].

Laparoscopic nerve-sparing radical cystectomy and construction of ileal neobladder was performed on a 76-year-old man with atrophic bladder after the intravesical instillation therapy for bladder cancer. Ileal neobladder was constructed by the combined extracorporeal technique through the camera port dilated to 45 mm. Operation time was 8 hours, with 3.5 hours for the nerve-sparing cystoprostatectomy, 2.5 hours for the extracorporeal neo-bladder construction and 2 hours for the laparoscopic urethra neo-bladder anastomosis and wound closing. The post-operative course was uneventful with minimum use of analgesia. This operation was minimally invasive therapy and from the functional aspect the potency was preserved. Although this method was technically challenging, various advantages can be promising for the patients compared to the standard open technique. Indication of this operation should be carefully expanded. Various methods, such as the complete intracorporeal technique and minimally invasive laparoscopic neobladder (MILaN) technique, have been reported for urinary diversion. In this report, we compared our method with other techniques.
