[Early bilateral nephrectomy in neonatal autosomal recessive polycystic kidney disease : Improved prognosis or unnecessary effort?]

Abstract

BACKGROUND:

Neonatal autosomal recessive polycystic kidney disease (ARPKD) is associated with giant kidneys, lung hypoplasia, pulmonal hypertension, and end-stage renal failure. Depending on the study, mortality is reported to range between 20 and 80%.

OBJECTIVES:

Does bilateral nephrectomy improve survival?

PATIENTS AND METHODS:

Between 2010 and 2016, we treated 7 children with prenatally diagnosed ARPKD. All had a planned delivery by cesarean section. After birth, oscillated ventilation with nitrogen enrichment was initiated to achieve maximum oxygenation and to decrease pumonary hypertension. All children had bilateral massive kidney hyperplasia (length 13-16 cm).

RESULTS:

Nephrectomy on one side was performed within 72 h together with placement of a peritoneal dialysis catheter in the intensive care unit. Contralateral nephrectomy was performed after 1-2 weeks when the child was stabilized by dialysis. In 2 children, kidney transplantation has already been performed and they are doing fine. One child died after 10 months due to infection. The other children are stable on home peritoneal dialysis awaiting transplantation.

CONCLUSIONS:

Early bilateral nephrectomy in neonatal ARPKD is feasible, but requires distinctive care at a pediatric intensive care unit and a high amount of organizational efforts to treat these children adequately in the first few days. In our experience, the procedure is a promising approach to improve ventilation and enable dialysis. However, kidney transplantation, best from a living donor, is required within the first years of life.
