Haematurea in pre-eclampsia: is it due to magnesium sulfate therapy?

The study was performed on 74 in-patients, sixty two were suffering from severe pre-eclampsia who were treated by MgSO [4] [50 patients] and diazepam [12 patients]. Twelve patients with premature labour were treated by MgSO [4] as a tocolytic and served as a control group. Urine analysis and kidney functions were done to all patients. Plasma Mg concentrations were estimated as well. The study proved that MgS0 [4] magnified the sign of haematuria in severely pre-eclamptic patients but not inducing it in patients with pre-mature labour
