Urodynamics of ileal conduits in adults.
In 11 adults with ileal conduits, urodynamic, radiologic and radioisotope studies were performed. Under physiological conditions the conduits revealed a low-volume/low-pressure state due to continuous drainage of urine by passive and active mechanisms. Conduito-renal reflux was found in all patients under high pressure conditions, such as having the patient cough and strain, or with the conduit filled up to maximum capacity after blockage of the stoma. The 'physiological' low-volume/short-term reflux obviously did not harm kidney function, as shown by radiologic and isotope studies.
