A Problem that Affects Millions of Men

Normal and Enlarged Prostate

Benign Prostate Enlargement

Benign prostate enlargement or hypertrophy affects most men over the age of fifty. The incidence of prostate enlargement increases with age and by eighty, 90% of men will experience this problem. Significant numbers of these men will develop symptoms and will require treatment.

What Is The Prostate?

The prostate is a gland that produces most of the fluid contained in the ejaculate. Because of its location at the opening or neck of the bladder, enlargement of the prostate affects urination. The prostate is often likened to a donut, surrounding the base of the bladder. Urine flows through the opening. Enlargement of the prostate with consequent diminishing of the opening in the "donut," can produce urinary obstruction.

How Do I Know If I Have Prostate Enlargement?

Health professionals recommend that men over fifty have an annual prostate exam (even if they have no symptoms), easily performed as part of a routine physical examination. A doctor checks the size and shape of the prostate by gently palpitating it through the wall of the rectum. This quick and painless examination allows the doctor to find early signs of prostate problems.

Prostate enlargement can produce the following symptoms:

  • Weak urinary stream
  • Hesitancy of the urinary stream
  • Interrupted urinary stream
  • Night time urination
  • Urinary frequency
  • Urinary urgency
  • Sensation of incomplete emptying of the bladder

Enlargement of the prostate can also produce the following which often require treatment:

  • Prostate and bladder infection
  • Bleeding from the prostate
  • Bladder stones
  • Kidney damage
  • Urinary retention or the absolute inability to urinate, requiring the passage of a catheter

Treatment Of The Enlarged Prostate

Treatment for benign prostate hypertrophy includes traditional surgery to remove the obstructing tissue, and drug and other therapies. These methods work, but can produce side effects and complications. TUNA (transurethral needle ablation) of the prostate is a procedure which is safe, and effective and minimizes side effects and complications.


T rans U rethral N eedle A blation of the prostate is a method of treating prostate enlargement using radio-frequency energy. This energy is delivered to the prostate via a small scope which is passed through the urethra. TUNA needles are inserted into the lobes of the prostate under vision [video].The energy source is then activated to treat these areas. Subsequently,the treated areas are absorbed resulting in shrinkage and diminution of symptoms.

Note: Dr. Schrager does not use a catheter after his TUNA procedures.

What are the advantages of T U N A ?

TUNA is performed safely , quickly and comfortably in the office under local anesthesia. Side effects and complications [including sexual and urinary control issues] rarely occur. You can contact Dr Schrager to discus your particular situation to determine what solution is best for you.
