[Preventive hemodialysis using a bath rich in bicarbonates in a pregnant woman with chronic kidney failure].

Patients with chronic renal failure requiring maintenance hemodialysis at the end of pregnancy are not as uncommon as pregnant women previously treated by this therapy. Prophylactic bicarbonate hemodialysis may allow the continuation of pregnancy until delivery of living baby. We report a 22 year old woman with chronic renal failure due to pyelonephritis secondary to bilateral reflux. Hypertension, metabolic acidosis and hydramnios happened at the 13th week (creatinine clearance 16 ml/min). Thirteen bicarbonate hemodialysis periods were necessary up to the 34th week when delivery by cesarean section was achieved giving birth to a 1500 g hypotrophic boy.
