First experience with a new form of orthotopic ileal neobladder (Leuven N-Pouch) following radical cystectomy.

Bladder cancer is the most common malignancy of the urinary tract. Radical cystectomy with pelvic lymph node dissection and a urinary diversion (UD) is the gold standard treatment of non-metastatic muscle-invasive bladder cancer (MIBC). Although ileal conduit is the standard and most commonly performed type of UD, more number of centers have recently started to perform orthotopic ileal neobladder (OIN). A novel OIN has been described in 2005 as the so-called "Leuven N-pouch", which combines the features of the commonly used Hautmann and Studer neobladders. Herein, we report our first experience with a case of Leuven N-pouch in our department, which was performed for a male patient with MIBC.
