Renoprival growth following treatment of unilateral Wilms' tumour.

The renal growth pattern following uninephrectomy for Wilms' tumour was analysed in 18 boys and 18 girls by means of a comparison between renal parenchymal and body surface area. No straightforward correlation was noted between age at nephrectomy, chemo- and radiation therapy applied, and subsequent renoprival dimensions. Five years on average after operation, a mean renal size corresponding to approximately 125 per cent of the normal for one of two healthy kidneys was recorded. However, wide variations in size were observed, but only 10 patients had a compensatory growth of the remaining kidney equivalent to that seen in patients nephrectomized for unilateral, non-malignant renal disease.
