Color Doppler sonography, Percutaneous nephrostomy, Postrenal renal failure
We report a case of postrenal renal failure resulting from advanced uterus carcinoma evaluated by color Doppler sonography before and after treatment. A 68-years-old woman was hospitalized with postrenal renal failure resulting from bilateral ureteral obstruction caused by advanced uterus carcinoma. Color Doppler sonography was used to determine site of nephrostomy. Nephrostomy was performed on the right kidney, which color Doppler sonographic examination showed to function better than the left kidney. After surgery color Doppler sonography of the right kidney showed recovery from renal dysfunction before serum uremic toxins had returned to their normal levels. These observations suggest the value of color Doppler sonography in estimating degree of renal function both before and after treatment of renal failure.
