Urology

We perform some prostate cancer-related procedures in our office. For others, we partner with our colleagues at the Mass General Cancer Center at Emerson Hospital. Our expert urologists provide comprehensive cancer care, including:

• Focal Cryoablation for Prostate Cancer – A groundbreaking, minimally-invasive procedure that targets cancerous cells without removing the prostate. This highly precise approach reduces side effects and speeds up recovery.
  • Why Choose Focal Cryoablation? This procedure offers a faster recovery, fewer complications, and a better quality of life than traditional surgery or radiation. Patients typically return to normal activities within a few days.
  • The Emerson Advantage – Dr. Louis Liou, MD, PhD, leads our focal cryoablation program and is one of the only physicians in New England specially trained in this technique. With over a decade of experience and hundreds of successful cases, he is a pioneer in using this technology to provide better outcomes for prostate cancer patients.
  • How It Works – The procedure uses MRI and ultrasound guidance to precisely target cancerous tissue with needle-thin probes. These probes freeze the affected cells to -100 degrees Celsius, destroying the cancer while preserving healthy tissue.
  • Who Can Benefit? Focal cryoablation is often ideal for men with localized prostate cancer or those experiencing recurrence after radiation therapy.
• NanoKnife for Prostate Cancer – A treatment technology that uses irreversible electroporation (IRE) to destroy diseased tissue, particularly cancer cells, by delivering electrical pulses through thin needles. This technique, also called NanoKnife surgery, is minimally invasive and aims to target cancer while preserving surrounding healthy tissues.
• Multiparametric MRI – A specialized scan that detects prostate cancer with high precision, allowing for better treatment planning.
• Complex Kidney Cancer Surgery – Including partial nephrectomies performed by specialists who have authored a leading textbook on renal cancer.

Benign prostatic hyperplasia (BPH) is a common condition that can cause frequent urination, weak stream, or difficulty emptying the bladder. Our urologists offer a variety of advanced treatments, including:

• GreenLight™ Laser Therapy – Uses a laser to vaporize excess prostate tissue and restore normal urine flow.
• Rezūm™ Water Vapor Therapy – A quick, office-based procedure that shrinks the prostate using steam.
• UroLift® System – A minimally-invasive treatment that lifts and holds the prostate away from the urethra, improving urine flow.
• Transurethral Resection of the Prostate (TURP) – A surgical option for more severe cases.

Patients with kidney, bladder, or ureteral stones benefit from the latest non-surgical and minimally-invasive treatments:

• Extracorporeal Shock Wave Lithotripsy (ESWL) – Uses sound waves to break up stones so they can pass naturally.
• Ureteroscopy – A small, flexible scope removes stones in the ureter.
• Percutaneous Nephrolithotomy (PCNL) – A procedure to remove larger kidney stones through a tiny incision.

Our specialists provide discreet and expert care for conditions affecting men’s reproductive health:

• Erectile dysfunction treatments, including medications, injection therapy, and prosthesis surgery
• Male infertility evaluations, vasectomy, and vasectomy reversal

We offer surgical and non-surgical options to help men and women manage incontinence, including physical therapy and advanced surgical treatments.

We provide expert care for common pediatric urologic conditions, including undescended testes and hydrocele. Our Pediatric Intervention Team ensures a comfortable experience for young patients and their families.
