[Changes in renal hemodynamics following experimental unilateral hydronephrotic transformation].

Electromagnetic flowmetry was used to study hemodynamics in both kidneys of 10 dogs in the presence of hydronephrotic transformation in one of the kidneys and increasing intrapelvic pressure. It was ascertained that nephrectomy of the hydronephrotic kidney affects the hemodynamics of the other one. As hydronephrotic transformation developed and intrapelvic pressure rose the blood flow in the kidney decreased while in the contralateral one dropped down. One month after the operation the blood flow in the kidney decreased 2-fold, and intrapelvic pressure increased 10-fold. Meanwhile on the contralateral side the blood flow increased by 30%. Nephrectomy of the hydrophrotic kidney resulted in further increase in the blood flow of the remaining organ.
