We provide prompt and compassionate care for adult and pediatric patients with genitourinary conditions, including: prostate, kidney, and bladder cancer, prostate enlargement, voiding dysfunction, urinary incontinence, overactive bladder, kidney stones, and sexual dysfunction.

We now feature the Urolift treatment for Benign Prostatic Hyperplasia, or BPH, is a condition in which the prostate enlarges as men get older. BPH is a very common condition that affects over 40 million Americans and over 500 million aging men worldwide. Over 40% of men in their 50s and over 70% of men in their 60s have BPH. While BPH is a benign condition and unrelated to prostate cancer, it can greatly affect a man’s quality of life.  As the prostate enlarges, it presses on and blocks the urethra, causing bothersome urinary symptoms such as:

• Frequent need to urinate both day and night
• Weak or slow urinary stream
• A sense that you cannot completely empty your bladder
• Difficulty or delay in starting urination
• Urgent feeling of needing to urinate
• A urinary stream that stops and starts
