COLI,ECriON OF URIXE FROM EACH KIDNEY 385 union is made much easier by using as a splint a small No. 5 ureteral catheter.This is first passed up the ureter toward the kidney for a sufficient distance andthen its lower end passed in through the incision in the uterus until it appears atthe vulva. The ureter is then stitched to the uterus with a few interrupted stitchesof blood-vessel silk. The cornu of the uterus above the point of anastomosis isthen ligated in order to prevent the extension of urine in an upward direction, andsimilarly the opposite cornu is then closed and the catheter appearing through the

nmatic sketch of anastomosis belwedetail of anastomosis using ur vulva is cut off so as to be inaccessible to the dog. If it be intended to prolongthe obser\-ations over a considerable period of time, it is easy to avoid the com-plications which might be caused by the advent of catamenia by the removal ofthe ovaries at the time the anastomosis is made. We thus have established a condition in which the urine drains through thecatheter into the vagina for a period of approximately 48 hours, after which thecatheter can be safely withdrawn by forceps introduced into the vulva. At the 386 THE JOURNAL OF LABORATORY AND CLINICAL MEDICINE end of one week it is possible to collect the products of each kidney in the follow-ing fashion: A glass tube is adjusted so as to fill the vulva and with this in placecollection can be made over the required time period. The urine from the bladderis subsequently withdrawn by catheterization through the urethra. Analysis ofthe urine collected by this uterova
