RENAL ANOMALY number sizelocation relationships structures

RENAL APLASIA This is due to the lack or lag of primary kidney duct (Wolffian duct), as well as aplasia izolateralnogo primary nucleus, from which the image of the corresponding half of the urinary tract. Bilateral aplasia of the kidney is an extremely rare birth defect not compatible with life.
