Pregnancy associated with renal glucosuria.

On reviewing 17,647 pregnancies over a 6-year period, 291 of 17,229 singleton pregnancies were noted to be associated with renal glucosuria. On analyzing these 291 pregnancies in 277 women, renal glucosuria was more frequently observed in those women with blood group types A and B and less in those with blood group type O. The incidence of renal glucosuria in nulliparous women, 2.8%, was significantly higher than that in parous women, 1.1%. A significantly high incidence of prematurity, 25.0%, was noted in women who persistently spilled a large amount of glucose.
