To the Editor,

We thank Pahwa et al[1]for their interesting study, "postpartum acute kidney injury (AKI)" published in Saudi Journal of Kidneys and Transplantation.

The authors described post-partum AKI including causes of renal failure and preva- lence, which are very informative. The investi- gators defined AKI and classified it according to the risk, injury, failure, loss, and end-stage renal failure criteria[2]based on changes in serum creatinine or changes in urine output or both. However, we are wondering how the investigators defined patients' body weight in the study for urine output criteria. As the post- partum patients would lose their body weight after baby delivery. Moreover, they are at risk of body weight alteration daily from dehy- dration, hemorrhage, or volume resuscitation. Type of body weight, ideal or actual body weight, would affect the AKI diagnosis by urine output criteria since acute body weight is more sensitive and ideal body weight is more specific.[3]



Conflicts of interest: None declared.
