Fertility is depressed in women with advanced CKD and ESRD and improves after transplant. Women with ESRD are at higher risk for pregnancy complications and loss. We sought to identify trends in delivery incidence amongst women with ESRD receiving renal replacement therapy (RRT) in the United States Renal Data System (USRDS).


We identified deliveries from inpatient claims of all prevalent female ESRD patients aged 18-44 yrs (n=650,282) between 2002-2015. Treatment modality at time of delivery was taken from treatment history files. Modality assignment for non-pregnant women was defined as last modality reported in each year. Rates were expressed as number of delivering women for every woman of child-bearing age receiving that RRT modality within each year. Logistic regression examined associations between patient characteristics and delivery.


1833 deliveries were observed over the study period. Delivery rates increased overall from 0.23% to 0.34% from 2002-2015 (Figure). Rates were highest for transplant patients, while PD patients had significantly lower rates. Older age was associated with lower odds of delivery (OR=0.91 for each additional year, 95% CI: 0.91-0.92). Black and Hispanic women (compared to White) were more likely to deliver (OR=1.46, 95% CI: 1.29-1.65 and OR=1.44, 95% CI:1.26-1.65, respectively), as were women whose primary cause of ESRD (compared to diabetes) was glomerulonephritis (OR=1.78, 95% CI=1.49-2.13) and hypertension (OR=1.65, 95% CI: 1.35-2.02). For each additional year after ESRD diagnosis, the odds of delivery were lower by 3% (OR=0.98, 95% CI: 0.97-0.99).


The absolute number of deliveries for women of childbearing age with ESRD remains low, but is increasing. The rate of delivery in women receiving HD nearly doubled between 2002 and 2015. Further work is needed to identify factors contributing to this increase. Younger women with shorter ESRD vintage are more likely to deliver and it may be prudent to focus family planning counseling to this subset of patients.
