UV reflux (bilateral) Iii in the rt.

My daughter suffered UTI along with high fever for four times in the last one and half years. she lost her appetite in that  time and also lost her weight. By USG we came to know about the following problems, 1) The pelvicalyceal system of the left kidney is mild to moderately dilated. The parenchyma of the left kidney appears mildly compressed, echogenic with ill defined corticomedullary junction. (2) The pelvicalyceal system of the right kidney is minimally and irregularly dilated. (3) The left ureter is mild to moderately dilated and traced upto the bladder. The right ureter is minimal to mildly dilated. (4) The prevoidal volume is 241 ml and the residual volume is 92 ml. Then doctor asked to do the MCU test. we did that and the result is she has UV reflux (bilateral) grade IV Lt. & grade III in the Rt.
