In cases of ileocystoplasty, which is an operation to increase the capacity of the bladder using a portion of the ileum, absorption of electrolytes from the reconstructed bladder is one of the most important problems. In 30 dogs absorption of radioactive isotopes Na^<22> and Cl^<36> from the reconstructed bladder was traced. The bladder was reconstructed with following various techniques: l) ileocystoplasty with closed loop method of Rubritius 2) ileocystoplasty with open flap method (Tasker), 3) bladder reconstruction with reversed seromuscular graft from the ileum and 4) bladder reconstruction with a portion of the stomach. In all cases both ureters were anastomosed to the abdominal skin to prevent the changes of intravesical fluid volume. The obtained data were compared with the absorption from the normal bladder. The results were as follows: l) Marked absorption of Na^<22> and Cl^<36> was traced from the mucous membrane lined bladder, regardless of the operative technique, closed loop method or open flap method. 2) Absorption from the bladder reconstructed with a portion of the stomach was of slighter degree. This fact indicates that from the view-point of electrolytes absorption the stomach wall will be more suitable for reconstruction of the urinary tract than the ileum. 3) Absorption from the bladder reconstructed with reversed seromuscular graft was minimal in the same degree as from the normal bladder. This method may be an ideal method of bladder reconstruction as far as the absorption of electrolytes concerns. 4) No conclusive data concerning deferential absorption of Na^<22> and Cl^<36> were obtained from this experiment.
