After Your GreenLightTM Procedure

Because this is an outpatient procedure, you will typically go home within a few hours of treatment. You should have someone drive you home after the procedure.

If a catheter was placed in your bladder at the end of the procedure, it will typically be removed within 24 hours. However, patients with compromised bladder function or those who require prolonged catheterization as a result of severe urinary symptoms may require a catheter for a longer period of time.

Most patients experience very rapid relief of symptoms and a dramatic improvement in urine flow. This typically occurs within 24 hours of the procedure. However, medical history, health condition, and other factors can influence treatment recovery.

  • You may experience mild discomfort, such as slight burning during urination, and small amounts of blood in your urine for a week or so. Also, depending on the condition of your bladder, you may experience greater frequency and urge to urinate. This will resolve over time as your bladder adjusts to removal of the obstruction in your urethra
  • You may be given an antibiotic to help you avoid infection. For discomfort, nonsteroidal anti-inflammatory drugs are options
  • Typically, you may return to normal activities 2 to 3 days after the procedure
  • You should not engage in sexual activities for about 2 weeks following the procedure1
  • Activities that may lead to blood in the urine, such as strenuous exercise (including heavy lifting, bike riding, or running on a treadmill) and working with vibrating equipment (sitting on lawnmowers or snow tractors), must also be avoided for at least 2 weeks2
  • Mild episodes of blood in urine are possible 1 to 2 weeks after the procedure, for which anti-inflammatory medication may be prescribed2
