Kidney biopsy during pregnancy: a difficult decision. A case series reporting on 20 patients from Mexico.

Background: Kidney biopsy is a routine procedure in the diagnosis of kidney disease, but during pregnancy it carries potential adverse effects for both mother and child, aside from the challenges of obtaining adequate tissue samples. Nevertheless, a precise diagnosis is necessary when specific and potentially toxic treatments are to be used during pregnancy. The present report presents our experience with regard to the usefulness and safety of kidney biopsies during pregnancy.

Collapsing Lesions and Focal Segmental Glomerulosclerosis in Pregnancy: A Report of 3 Cases.

The relationship between focal segmental glomerulosclerosis (FSGS) and pregnancy is complex and not completely elucidated. Pregnancy in patients with FSGS poses a high risk for complications, possibly due to hemodynamic factors, imbalance between angiogenic and antiangiogenic factors, and hormonal conditioning. Although poor clinical outcomes associated with collapsing FSGS are common outside of pregnancy, the prognosis during pregnancy is not well documented.

Acute kidney injury in pregnancy and the role of underlying CKD: a point of view from México.

The incidence of acute kidney injury in pregnancy (P-AKI) in developed countries is significantly lower than in developing ones, where it is estimated to range between 4 and 26%. Mortality in cases of P-AKI requiring dialysis is high, varying from 20 to 80%. In developing countries, clinical decisions are often based on the availability of services and not on needs.
