Impact de l'ascite urinaire fœtale sur le taux de β2 microglobuline sérique dans les uropathies obstructives : à propos d'un cas

We report a posterior urethral valves case diagnosed at 33 week's gestation on a fetus presenting with anamnios and urinary ascites. In this fetus, the serum β2 microglobuline rate was high, suggesting a very poor renal prognosis. At 1-year-old, the creatinine rate is nearly normal. In case of urinary ascites, the serum β2 microglobuline rate could be improved in relation with the transperitoneal reabsorption of this protein.
