(ureteronephrectomy) n. the surgical removal of a kidney together with its ureter. This operation is performed for cancer of the kidney pelvis or ureter. It is also undertaken when the kidney has been destroyed by *vesicoureteric reflux, to prevent subsequent continuing reflux into the stump of the ureter that would occur if only the kidney were removed.
n. surgical removal of a ureter. This usually includes removal of the associated kidney as well (see nephroureterectomy). If previous nephrectomy has been performed to remove a kidney that has been destroyed by *vesicoureteric reflux or because of a tumour of the renal pelvis, subsequent ureterectomy may be necessary to cure reflux into the stump of the ureter or tumour in the ureter, respectively. Less commonly, in certain cases an isolated segment of a ureter may be removed for a short ureteric stricture or ureteric tumour.... ureterectomy
