Usually reserved for those patients with minimal symptoms (AUA-PSS < 7) from their BPH. Although symptoms are not particularly bothersome, these patients should still continue to seen their physicians regularly (yearly) for examinations and routine laboratory tests. These tests are designed to avoid having urine back up toward the kidneys (hydronephrosis) or bladder decompensation ("silent prostatism"). Patients followed by observation may eventually require medications or surgical interventions for their BPH if they develop complications of their BPH such as: bladder stones, urinary retention (inability to urinate), recurrent urinary tract infections, or signs of kidney damage.
