Objective  To observe the prognosis of pregnant patients with renal failure who underwent blood purification. Methods  Pregnant patients with renal failure undergoing blood purification (hemodialysis or hemofiltration) from January 2009 to February 2017 were included in this study. Clinical data and pregnancy outcome were collected retrospectively. Results  A total of 42 patients were enrolled in this study, including 38 with acute renal failure, 3 with chronic progressed renal failure, and 1 with chronic renal failure. There were 5 patients (11.9%) with chronic kidney disease (CKD) before pregnancy, 3 (7.2%) with systemic lupus erythematosus, 24 (54.8%) with hypertension, 5 (11.9%) with acute pancreatitis, and 7 (14.3%) with acute liver failure. In perinatal period, 7 patients (16.7%) died, whose underlying diseases were acute pancreatitis in 2, lupus nephritis in 1, acute hepatic failure in 3, and pulmonary tuberculosis breakout in 1. There were 5 patients with twin pregnancy, and 37 patients with single pregnancy. In the 28 patients with natural pregnancy ending, the live birth rate was 82.1% (23/28), and the live birth rate of twin pregnancy was only 50% (5/10). Twenty-seven patients were followed up, in whom 10 were in end stage of renal disease (ESRD), which was correlated with hypertension (P=0.001), and 3 patients were in CKD 1–4. Renal diseases were completely recovered in 14 patients. New CKD were diagnosed in 8 patients, without any correlated factor. Conclusions  For pregnant patients with renal failure undergoing hemodialysis or hemofiltration, the death risk and the dead birth rate are high. Patients with hypertension or pre-existed renal failure have higher risk for ESRD. Some patients are not completely recovered from acute renal failure, with CKD left.
