Old-Fashioned Values

“My dream in urology has always been to treat patients like family with the old-fashioned values of respect, integrity, and compassion to give you the kind of care that you deserve. My fellowship training gives me the knowledge and skills to utilize the latest technology for the benefit of my patients.”

BPH or Benign Prostatic Hyperplasia (Enlargement of the prostate)

One of the most common issues I see in the office is BPH or Benign Prostatic Hyperplasia. That's the medical term for enlargement of the prostate. It doesn't mean much without the symptoms: weak stream, hesitancy, straining, nighttime urination, urgency, frequency, and incomplete emptying. Find out more about BPH and what to do about it.
