Chronic incomplete obstruction of the ureter: a new experimental model.
To produce a chronic moderate hydronephrosis in dog, a method of partial ureteral occlusion using a specially designed polypropylene obturator was developed. In 11 of 14 dogs undergoing this procedure, excretory urography constantly revealed a moderate degree of hydronephrosis persisting for 7 weeks. Combination of this method in one ureter with the vaginal-cuff cutaneous ureterostomy, previously reported, in the contralateral ureter is a useful model for split renal function study of unilateral chronic hydronephrosis or obstructive nephropathy analogous to that of clinical case.
