Some issues Dr. Daniel H. Williams IV, MD can help you with:

Benign Prostatic Hyperplasia (Enlarged Prostate)

Benign prostatic hyperplasia (BPH) is a noncancerous condition in which the prostate gland becomes enlarged. BPH affects about half of men between the ages of 50 and 60, and approximately 80% of men over 80. As the prostate grows in size, it can press down on the tube where urine flows out of the body (the urethra) and cause urinary problems.

Medication can relieve mild to moderate symptoms of BPH, such as frequent urination, incomplete bladder emptying, a weak urine stream, and straining while urinating. However, other forms of treatment may be more appropriate if an individual has pain with urination, frequent urinary tract infections, or is unable to urinate. The size of the prostate and the severity of their symptoms will determine the type of treatment they need. If the prostate is not very large, doctors will likely recommend a transurethral procedure. This minimally invasive technique involves the insertion of a scope into the urethra. The most common transurethral procedures for BPH are:

Transurethral incision of the prostate or TUIP, where the surgeon uses the scope to make small cuts in the area of the prostate that meets the bladder. These cuts will open up the pathway for urine and allow it to flow with more ease.
Transurethral needle ablation or TUNA, where needles are inserted through the scope and into the prostate. The needles use radiofrequency waves to destroy excess prostate tissue.
Laser prostate ablation, where lasers pass through the scope to melt away the part of the prostate causing urine blockage.
Transurethral resection of the prostate or TURP, where the inside of the prostate is trimmed and removed one tiny piece at a time using the scope.

If the prostate is too big for a transurethral procedure, an individual may need a simple prostatectomy, which can be done in one of three ways: laparoscopic, robotic, or open. During a laparoscopic simple prostatectomy, a surgeon makes several small incisions on the belly. Then they insert a long tube with a camera into one of the cuts and surgical instruments into the others. Using the camera to see inside the belly, they carefully removes the enlarged part of the prostate. Robotic simple prostatectomy uses the same techniques as the laparoscopic method, but the surgery is done with the help of a robot. For men with very large prostates, open simple prostatectomy may be the best treatment option. This surgery differs from the other approaches in that it requires a much larger incision.

Most transurethral treatments for BPH, like TUIP, TUNA, and laser prostate ablation, are done in the doctor's office or outpatient surgery center. TURP and simple prostatectomy, however, need to be performed in the hospital and require an average stay of one to three days. Patients should wait a week before doing any strenuous activities after a TUIP, TUNA, or laser prostate ablation, and about four to six weeks after a TURP or simple prostatectomy. Although these treatments improve BPH symptoms for most patients, it is important to be aware of the risks involved, such as urine control issues, tightening of the urethra, and erectile dysfunction.

Biopsy

A biopsy is a procedure performed to remove a small sample of cells for testing. The cells are examined in a laboratory to check for disease, or sometimes to see how badly a known disease is affecting them. Biopsy can be performed on any part of the body.

Although biopsy is most often associated with cancer, it can also be used to check for other diseases, such as infections. A biopsy sample can be scraped, cut, collected with a needle, taken with a machine that punches out a tiny piece, or removed with the tiny tools in an endoscope.

In most cases, a biopsy is a simple outpatient procedure. Depending on the procedure, patients may need to stop taking certain medications beforehand, such as blood thinners. It is important for patients to tell doctors if they are pregnant, as certain biopsies require the use of x-rays to guide the needle to the right location. There is usually very little pain associated with a biopsy. Patients will have to wait a few days to hear the results.

Shock Wave Lithotripsy

Stones are formed when mineral deposits build up and harden in an organ or gland. For example, urine contains minerals that can form crystals and result in kidney or bladder stones. Stones can also occur in other parts of the body, like the mouth. Salivary gland stones form when the chemicals in the saliva harden and get stuck in the tiny ducts of the salivary glands. Pain and swelling are the most common symptoms associated with stones.

Lithotripsy is a procedure used to break up small stones. Shock wave lithotripsy, the most common type of lithotripsy and least invasive way of treating stones, does this using high-powered sound waves. This procedure can treat many types of stones in the body, but it is most frequently used for urinary stones, such as kidney and bladder stones.

Shock wave lithotripsy can be done in one of two ways. Conventionally, this procedure is performed when someone is sitting in a tub of water, and the sound waves travel through the water to their body. A more recent alternative is to send the shock waves through cushions while a patient is lying on a table. Although shock wave lithotripsy is not surgery and requires no cutting, the patient will be given anesthesia before the procedure. Their body should be able to pass the broken-up urinary stones naturally in their urine after treatment. For other types of stones, another minimally invasive procedure may be required to remove stone fragments left by shock wave lithotripsy.
