Cystectomy is a medical term for surgical removal of all or part of the urinary bladder. It may also be rarely used to refer to the removal of a cyst, or the gallbladder. The most common condition warranting removal of the urinary bladder is bladder cancer. After the bladder has been removed, an urinary diversion is necessary. Ureterocutaneostomy, ureterosigmoidostomy, ileal conduit, continent cutaneous pouch formations and neobladder substutitions using intestinal segments are main types of urinary diversions. Even though ileal conduit has been known as the most common type of urinary diversion, contemporary surgical practice has evolved to use of neobladder substitutions as first choice. A neobladder substutition is constructed as a pouch from a section of ileum or colon, which can act as a form of replacement bladder, storing urine until the patient desires to release it, which can be achieved by either abdominal straining or self catheterisation. Future treatment for this condition may involve a full replacement with an artificial bladder.
