Colorectal surgeons and urologists commonly work together for a variety of complex pelvic diseases including malignancy, trauma, radiation, congenital anomalies, and/or neurogenic etiologies. When the bladder is removed, a urinary diversion must be constructed to assist with urinary storage and drainage. Bowel is the most reliable and commonly used tissue substitute in urinary diversion formation.1., 2., 3. There are two major types of urinary diversions: incontinent diversions, in which urine continuously drains from a stoma; and continent diversions, in which urine does not freely drain from a stoma. Continent diversions may further be subcategorized as orthotopic (urinary diversion is anastomosed to the native urethra and drainage occurs via increased intraabdominal pressure) and continent cutaneous (urinary diversion requires drainage via clean intermittent catheterization). Selection of an appropriate urinary diversion may be variable and depends on underlying bladder pathology, clinical history, and patient goals. The purpose of this report is to review the most common types of urinary diversions and their relevant complications for an audience of practicing colorectal surgeons who often share care for these complicated patients.
