Pregnancy associated with renal glucosuria.

Area of Science:

• Obstetrics and Gynecology
• Nephrology
• Human Genetics

Background:

• Renal glucosuria is a condition characterized by glucose in the urine.
• Pregnancy can alter renal physiology, potentially affecting glucose handling.
• The association between renal glucosuria, blood groups, and pregnancy outcomes requires further investigation.

Purpose of the Study:

• To investigate the incidence and risk factors of renal glucosuria in singleton pregnancies.
• To explore the relationship between renal glucosuria, maternal blood groups, and parity.
• To determine the impact of renal glucosuria on pregnancy outcomes, specifically prematurity.

Main Methods:

• Retrospective review of 17,647 pregnancies over a 6-year period.
• Analysis of 291 singleton pregnancies diagnosed with renal glucosuria.
• Comparison of renal glucosuria incidence based on maternal blood group and parity.

Main Results:

• Renal glucosuria was observed in 291 of 17,229 singleton pregnancies (1.7%).
• Higher incidence of renal glucosuria was noted in women with blood group types A and B compared to type O.
• Nulliparous women had a significantly higher incidence (2.8%) than parous women (1.1%).
• Women with persistent high glucose spilling had a significantly high incidence of prematurity (25.0%).

Conclusions:

• Maternal blood group and parity are associated with the occurrence of renal glucosuria during pregnancy.
• Persistent, significant glucoseuria in pregnancy is linked to an increased risk of prematurity.
• Further research is warranted to understand the mechanisms and clinical implications.
