      Hydronephrosis during pregnancy is a physiological phenomenon in the majority of pregnant women after the 20th week of pregnancy; normally it gives rise to no symptoms. Four cases of hydronephrosis causing symptoms during pregnancy are described, where ureteral colic has been the reason for hospitalization. An evaluation is given of the indications and the methods of treatment, including the employment of an indwelling ureteral catheter.
