Answer

Relief of the obstruction is the mainstay of therapy for postrenal azotemia. In anuria, bladder catheterization is mandatory to rule out bladder neck obstruction, whereas in progressive azotemia, catheterization should be done after the patient has voided to determine the postvoid residual volume. A postvoid residual volume of 100 mL or more suggests obstructive uropathy, and the cause should be further investigated.
