VERDECIA CANIZARES, Caridad  y  PORTUGUES DIAZ, Andrés. Value of the biopsy in the diagnosis of kidney tumors in children . Rev Cubana Pediatr [online]. 2004, vol.76, n.3, pp. 0-0. ISSN 1561-3119.

The ultrasonographic screen-assisted aspiration biopsy or the laparoscopy-assisted biopsy have been introduced by some medical centers to diagnose from the histological point of view different types of kidney tumors in children. 15 patients diagnosed at "William Soler" Pediatric Teaching Hospital from March 1995 to March 2003 were included in the study. All of them had clinical and imaging diagnoses of malignant kidney tumors. This study was aimed at differentiating the histological variant of the tumor before applying any type of treatment and at reducing this way preoperative morbidity.
