Abstract
Of 17 dogs, 14 developed hydronephrosis which was moderate to severe in degree after excision of a strip of proximal ureter. Of 6 control animals, 5 had persistence of worsening of hydronephrosis, demonstrating that this technique produces a lasting and significant ureteral stricture. Eight animals were treated by Gruntzig balloon dilatation of the stricture 3 wk-6 mo. after ureteral narrowing. Of the dogs thus treated, 7 exhibited prompt and marked improvement of their hydronephrosis without relapse during the followup period. Percutaneous ureteral stricture dilatation seems a promising technique, at least for the treatment of postoperative strictures which are discovered relatively soon after surgery. Successful dilatation, without the need for internal stenting or subsequent nephrostomy drainage, will minimize morbidity and significantly reduce costs.
