"We have performed experimental bilateral extravesical Ureteroneocystostomy in dogs. The technique of procedure was as follows : A longitudinal myotomy incision was made near the bladder dome directed forward the bladder neck for 2cm and then separated to allow the mucosa to pout. A 1 cm incision was then made in the bladder mucosa at the distal end of the detrusor incision. Excess ureter was excised and the ureter spatulated for 1 cm. A 6-0 Prolene suture was then placed at each apex and fullthickness of ureter anastomosed to the bladder mucosa in one layer with a continuous, nonlocking stitch. The myotomy incision was then closed over the ureter with interrupted 4-0 chromic catgut. The surgical wound was closed without drains. The roentgenographic findings and gross findings of the ureter and kidney were observed on the 3 wks after the operation For microscopic observation of the ureteroneocystostomy site were observed. The results are as follows: 1. Retrograde cystographic finding showed on ureterovesical reflux in 6 dogs. 2. Intravenous urographic findings were no hydronephrosis and dye were well drained into the bladder, except 1 dog which showed severe hydronephrosis on right kidney and mild hydronephrosis on left kidney. 3. Gross findings of ureter and kidney revealed no obstruction and renal enlargement, except one dog showed incomplete bilateral obstruction on ureteroneocystostomy site."
