Absorbability of mucosa in total replacement of urinary bladder with jejunum. An experimental study

The absorption of urine components in jejunum substitute for the urinary bladder was studied experimentally in dogs. For this purpose, determination of the blood urea, creatinine, and electrolyte levels as well as measurements of the radioactivity in blood samples after intravesical instillations of radioactive iodine, were done at various intervals after total replacement of the urinary bladder with jejunum. The absorption was found to decrease greatly in one month and to be negligible one year postoperatively.
