Some issues Dr. Mitchell R. Humphreys, 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.

Kidney Stones

Kidney stones are hard deposits that form in the kidneys, made up of minerals that are normally present in urine. They can vary in size, from as small as a grain of sand to as large as a nickel, occasionally even larger. Sometimes they lodge in the kidney, and sometimes they break free and make their way out through the urinary tract, which can be extremely painful.

Kidney stones can be smooth or jagged and are yellow to brown in color. They are mostly comprised of the minerals calcium, oxalate, and phosphorus. Examining the stones to see what they are made of can show what caused the stone to be formed in the first place. For example, a stone made of mostly calcium, which is the most common type, can happen any time the urine becomes too concentrated due to dehydration or a blockage in the kidney. A uric acid stone forms when acid levels in the urine get too high, usually due to excessive consumption of animal protein such as meat and fish. A struvite stone is a sign of certain infections, and a cystine stone can be due to a genetic disorder that raises the risk of kidney stones.

The most common symptom of kidney stones is pain, either in the back or lower abdomen, or severe pain when urinating. There may also be blood in the urine. Treatment for kidney stones depends on how large the stone is. Very small stones can pass out of the body on their own, and they do not require treatment other than drinking adequate water and taking pain killers. Larger stones need to be broken apart and removed. The main treatment options are:

Shock wave lithotripsy, which uses sound wave vibrations to break apart the stone
Percutaneous nephrolithotomy, or the use of a very tiny tool (like a wire inserted through the back) to break apart and remove the stone
Ureteroscopy, a thin tube inserted through the urethra and bladder to the stone, where tiny tools can grasp the stone and remove

People who have had one kidney stone are at risk of developing another. To reduce this risk, patients are given instructions specific to the type of stone they developed. Generally the instructions will include drinking more water to dilute the urine, but it may also involve lowering sodium intake or eating less meat.

Radical Prostatectomy

Prostate cancer is uncommon in men under 40, but the risk of getting the disease significantly increases after the age of 50. If doctors suspect their patients have prostate cancer based on a physical exam or blood test results, he or she may recommend a biopsy. This diagnostic procedure collects tiny samples of tissue from the prostate, typically with the use of a special needle. The samples are then examined in a laboratory to determine whether any abnormal cells are present. Biopsies of the prostate are most often done transrectally, or through the rectum.

If a biopsy shows the presence of prostate cancer, doctors will discuss available options, such as watchful waiting, radiation therapy, hormone therapy, chemotherapy, and surgery. Together, the doctor and patient will develop a treatment plan that best fits the patients' condition. If a doctor recommends surgery, the patient will likely have a radical prostatectomy. There are three ways this prostate removal procedure can be performed:

Open radical prostatectomy, which uses a large incision, usually in the abdomen.
Laparoscopic radical prostatectomy, which requires several small incisions in the stomach. A long, thin tube with a camera is inserted through one of the cuts. The surgeon uses this instrument to view the inside of the belly during the operation.
Robotic radical prostatectomy, which uses the above laparoscopic techniques but with the help of a robot.

While incisions for the laparoscopic and robotic approaches will always be on the lower abdomen, there are two possible incision locations for the open procedure. More commonly, the cut will start just below the belly button and end at the pubic bone. The other possible but less frequently used incision location is the area between the base of the scrotum and anus. After the cut is made, the surgeon will separate the prostate from the tissues surrounding it. Extra care will be taken to cause as little injury as possible to the blood vessels and nerves. Patients will wake up from surgery with a small pouch that drains fluids from the belly and a long tube that drains urine from the bladder.

Radical prostatectomy is recommended for cancer that is contained within the prostate. If cancer has spread to other parts of the body, non-surgical treatments like chemotherapy, radiation therapy, or hormone therapy may be more appropriate.

The average hospital stay is one day for a laparoscopic or robotic radical prostatectomy, and one to three days for an open radical prostatectomy. Patients are advised to stay in bed until the morning following the operation. Strenuous activities like running and heavy lifting must be avoided for four to six weeks. Although radical prostatectomy aims to remove all of the cancer cells, patients will still need to see their doctor regularly after surgery to make sure that the cancer does not return.
