Answer

If complete ligation of the ureter occurs, the urine from the ipsilateral kidney is prevented from draining into the bladder, leading to hydronephrosis and progressive deterioration of ipsilateral kidney function. These events may occur with or without symptoms. If the urine in this obstructed system becomes infected, the patient will almost certainly become septic with pyonephrosis.
