Surgical tactics in the treatment of malignant renal tumors in childhood.

The authors report the treatment results of 89 children with renal tumors (excluding carcinoma) seen from 1988 to 1992, 71 (79.8%) with favorable-histology Wilms' tumor (survival 86%) and 18 (20.2%) with unfavorable histology, including anaplastic nephroblastoma, clear-cell sarcoma, and rhabdoid tumor (survival 61%). Preoperative chemotherapy (ChT) was given to 46 patients (survival 84%); none was given to 43 with either tumors in the 1st year of life, massive hematuria, or tumor growth during ChT (survival 78%). There were 3 tumor ruptures in the latter group compared to 1 in the former group.

[Diagnostic imaging methods in neonates with diseases of the urinary tract].

The actually used examination algorithm of imaging methods was checked in 35 neonates examined in the course of two years (1991 and 1992) on account of suspected diseases of the urinary pathways. It involved sonographic examination of 28 children, voiding cystourethrography (34x) and intravenous urography (18x). Ascendent pyelography and irrigography were performed three times, one neonate was examined by computed tomography. The procedure used as a basic sonographic prenatal screening in 11 children, in 20 clinical suspicion of disease of the urinary pathways, and four neonates were examined on account of an anorectal malformation or abnormality of the external genitalis. The most frequent finding--in 18 children--was hydronephrosis. It was associated with signs of subrenal obstruction (8x), with ren duplex (5x) and with a megaureter (6x). The association of the sonographic finding of dilatation of the intrarenal urinary pathways with absent contrast filling during excretory urography was observed in a child with hydronephrosis and subrenal obstruction and in four children with a multicystic dysplastic kidney. In individual cases the authors detected a valve of the posterior urethra, a sigmoid-vesical fistula, agenesis of the penis and stenosis of the urethra. Eleven neonates had a normal findings of the urinary tract.

[Disseminated histiocytosis X].

Three cases of 4-year-, 16-month- and 8-month-old children suffering from a disseminated form of histiocytosis X showed overlapping of Hand-Schüller-Christian syndrome and Letterer-Siwe syndrome in clinical picture, biopsy and autopsy. Morphological lesion does not develop simultaneously in all the organs. Some of them tend to steatosis and fibrosis of histiocytosis infiltrations, which the others do not.
