The recovery of function of chronically obstructed and infected ureters.

Twelve experiments in which intraluminal ureteral pressure, ureteral diameter, aortic blood pressure, and respirations were measured, and in which ureteral wall tension was calculated, were performed on 11 female dogs. These experiments demonstrated that the impairment in ureteral function caused by chronic obstruction and infection could be reversed after surgical correction of the obstruction in conjunction with antibiotic therapy.
