Percutaneous nephrostomy in the treatment of hydronephrosis during pregnancy: Our experience

1998

Hydronephrosis during pregnancy is commonly considered physiological due to compression of the ureters by the gravid uterus and by dilated ovarian veins. Only in symptomatic cases or secondary to obstruction is a urinary diversion required. Six cases of symptomatic hydronephrosis treated with percutaneous nephrostomy are reported. Tocolytic therapy was practised in order to avoid the risk of abortion.
