Instructions After Removal of the Catheter After Your Prostate Surgery

This information explains what to do after your catheter is removed after prostate surgery.

General Information for After Your Surgery

  • You may decrease your daily liquid intake to what you normally drink. You should drink 4 to 6 (8-ounce) glasses of liquids every day.
  • Limit your fluids after 7:00 pm and empty your bladder before you go to bed. This may prevent your having to get up at night.
  • Limit how much alcohol and caffeine you drink if you’re having a lot of urine leakage.
  • Blood in your urine 1 or 2 times in the 2 to 3 weeks after your surgery is usually because the the scab inside is coming off.
    • Try drinking more liquids. When you no longer see blood, go back to drinking the amount of liquids you normally drink.
    • Call your doctor if you see blood or blood clots in your urine for longer than 1 day.
  • Finish taking your antibiotics as prescribed.
  • Have your PSA drawn 6 weeks after surgery. This can be done at MSK or by someone closer to where you live. If you don’t have it done at MSK, have the results faxed to your doctor’s office.

Activity and Exercise

  • Start doing Kegel (pelvic floor muscle) exercises _________________. Do not push to urinate after the catheter is removed. Do not strain to move your bowels.
  • You may start sexual activity again __________________.
  • You may start taking medication to achieve an erection the night the catheter has been removed.
    • Take your nightly dose as directed:
      • Take sildenafil (Viagra®) 25 mg or vardenafil (Levitra®) 10 mg every night. Or you may take tadalafil (Cialis®) 20 mg every other day.
      • You can split a sildenafil (Viagra®) 100 mg pill into 4 pieces or a vardenafil (Levitra®) 20 mg pill into 2 pieces. Use a pill cutter from your local drug store.
    • Challenge:
      • Over the next 4 to 6 weeks after the catheter has been removed you should try to take a full dose of sildenafil (Viagra®) (100 mg) or vardenafil (Levitra®) (20 mg) once a week on an empty stomach.
        • Try this on 3 separate occasions before you return to see your doctor.
        • Do not take the regular nightly dose of sildenafil (Viagra®) 25 mg dose or vardenafil (Levitra®) 10 mg on the night you attempt the challenge.
      • If you’re taking tadalafil (Cialis®), you do not need to change your 20 mg dose. This is the highest dose you can take so you don’t need a challenge.
      • During the challenge try to become sexually aroused through contact with a partner or yourself. Write down what happened and tell your doctor during your next visit.

  • Call your doctor if you see blood or blood clots in your urine for more than 1 day.

  • Call your doctor 10 days after your surgery for your pathology results.
