Renal salvage procedure for synchronous bilateral Wilms' tumor

This report describes a renal salvage procedure performed in a 2-year-old g irl with bilateral renal tumors comprising a multilocular, cystic tumor of the right kidney and a solid and cystic nephroblastoma of the left kidney a fter chemotherapy. Surgery was performed because the right kidney became hy dronephrotic due to compression by the enlarged cysts, while the left tumor showed only minimal shrinkage even after three courses of chemotherapy. Th e right-sided cysts were simply unroofed and the left-sided tumor was extir pated by partial nephrectomy. Her postoperative course was uneventful with considerable recovery of the function of each kidney. This procedure should be considered if the pathological features of the tumor are relatively fav ourable.
