Abstract
ObjectiveTo investigate the clinical characteristics and prognoses of patients with postpartum acute kidney injury (PPAKI).MethodsWe retrospectively reviewed the clinical presentations, laboratory examinations, treatments, and outcomes of patients with PPAKI admitted to our hospital from January 2013 to December 2017. We then analyzed the clinical characteristics and prognoses of the mothers and their infants.ResultsOf 37 patients diagnosed with PPAKI, 26 (70.3%) received treatment in the intensive care unit, mainly for hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome (28/37, 75.7%), pre-eclampsia (26/37, 70.3%), and postpartum hemorrhage (22/37, 59.5%). Twenty patients required renal replacement treatment (RRT), but renal recovery times were similar in the RRT and non-RRT groups. Renal function recovered completely in 30 patients (81.1%) and partially in one patient (2.7%), and was not re-examined in two patients (5.4%). Three patients (8.1%) were lost to follow-up. Only one patient (2.7%) remained dialysis-dependent, and no maternal deaths occurred. The preterm birth, low birth weight, and infant survival rates were 70.7% (29/41), 68.3% (28/41), and 78.0% (32/41), respectively.ConclusionRRT does not reduce renal recovery time compared with non-RRT. Overall, the prognoses of both mothers and their fetuses are good following treatment for PPAKI.
