Blood in your urine

Risks of TURP can include:

• Temporary difficulty urinating. You might have trouble urinating for a few days after the procedure. Until you can urinate on your own, you will need to have a tube (catheter) inserted into your penis to carry urine out of your bladder.
• Urinary tract infection. This type of infection is a possible complication after any prostate procedure. An infection is increasingly likely to occur the longer you have a catheter in place. Some men who have TURP have recurring urinary tract infections.
• Dry orgasm. A common and long-term effect of any type of prostate surgery is the release of semen during ejaculation into the bladder rather than out of the penis. Also known as retrograde ejaculation, dry orgasm isn't harmful and generally doesn't affect sexual pleasure. But it can interfere with your ability to father a child.
• Erectile dysfunction. The risk is very small, but erectile dysfunction can occur after prostate treatments.
• Heavy bleeding. Very rarely, men lose enough blood during TURP to require a blood transfusion. Men with larger prostates appear to be at higher risk of significant blood loss.
• Difficulty holding urine. Rarely, loss of bladder control (incontinence) is a long-term complication of TURP.
• Low sodium in the blood. Rarely, the body absorbs too much of the fluid used to wash the surgery area during TURP. This condition, known as TURP syndrome or transurethral resection (TUR) syndrome, can be life-threatening if untreated. A technique called bipolar TURP eliminates the risk of this condition.
• Need for re-treatment. Some men require follow-up treatment after TURP because symptoms don't improve or they return over time. Sometimes, re-treatment is needed because TURP causes narrowing (stricture) of the urethra or the bladder neck.

• Blood thinners such as warfarin (Coumadin, Jantoven) or clopidogrel (Plavix)
• Nonprescription pain relievers such as aspirin, ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve, others)

• Blood in your urine. It's normal to see blood right after surgery. Contact your doctor if the blood in your urine is thick like ketchup, bleeding appears to be worsening or your urine flow is blocked. Blood clots can block urine flow.
• Irritating urinary symptoms. Urination might be painful, or you might have a sense of urgency or frequent need to urinate. Painful urination generally improves in six to eight weeks.

• Drink plenty of water to flush out the bladder.
• Eat high-fiber foods, to avoid constipation and straining during a bowel movement. Your doctor also might recommend a stool softener.
• Wait to resume taking any blood-thinning medications until your doctor says it's OK.
• Avoid strenuous activity, such as heavy lifting, for four to six weeks or until your doctor says it's OK.
• Hold off on sex for four to six weeks.
• Avoid driving until your catheter is removed and you're no longer taking prescription pain medications.

• Are unable to urinate
• Notice bright red blood or an increase in clots in your urine
• Notice that your urine isn't becoming more clear after drinking more fluid and resting for 24 hours
• Develop a fever above 100.4 degrees F (38C)
