Urologic Robotic Surgery

Urological Robotic Surgery for the Treatment of Malignant and Benign Conditions

When medication and other non-surgical treatments are unable to relieve symptoms, surgery may be recommended as a treatment option. At MedStar Washington Hospital Center, our urology specialists perform minimally invasive robotic surgery using the da Vinci  .

The da Vinci® Surgical System allows physicians to perform minimally invasive procedures through small incisions using robotic technology. The robot's unique EndoWrist instruments offer physicians the dexterity not available to them when using conventional laparoscopic instruments. By offering the surgeon, urologist or oncologist a high-definition 3-D view, the da Vinci surgical robot allows physicians to better distinguish vital muscles and delicate nerve tissues surrounding the operative area, preserving them.

Our Urological Robotic Surgery Specialists

Dr. Jonathan Hwang is the Chairman of Urology, the Director of Robotic Surgery at MedStar Washington Hospital Center and an Associate Professor in Urology at Georgetown University School of Medicine. Since 2003, he has completed more than 2,700 robotic surgeries including over 2,300 robotic prostatectomies to date. He is considered one of the foremost robotic surgery experts in urologic oncology in the mid-Atlantic region.

Dr. Lambros Stamatakis is leading minimally invasive, robotic surgery at the Hospital Center. His training includes a specialized fellowship in Endourology/Minimally Invasive Surgery at the Baylor College of Medicine, which has built a strong foundation for his experience with minimally invasive procedures.

Dr. Ross E Krasnow has extensive experience using robotic and minimally invasive surgical techniques for both cancer excision and reconstruction. He is fellowship trained in Urologic Oncology at Harvard Medical School affiliated hospitals (Massachusetts General Hospital and Brigham and Women’s Hospital). Dr. Krasnow specializes in robotic partial nephrectomy (transabdominal and retroperitoneal), nephroureterectomy, radical nephrectomy, radical cystectomy for bladder cancer, female anterior exenteration for bladder cancer, robotic intracorporeal urinary diversion, upper urinary tract reconstruction, and robotic radical prostatectomy.

Beneficial Treatments Using Robotic Surgery

Prostate Cancer

Prostate cancer is the most common cancer in men not involving the skin. Often times, men won’t notice any health problems, as prostate cancer tends to grow slowly. The treatment for prostate cancer is dependent on the patient’s specific diagnosis. Your physician will work in conjunction with you to decide which treatment option is best.

Robotic-assisted laparoscopic radical prostatectomy is the most common robotic surgery performed by the Urology Department at the Hospital Center. During the procedure, the prostate gland and the seminal vesicles are removed. This treatment is highly precise, contributing to its reputation as the standard of care for prostate cancer surgery.

Bladder Cancer

The bladder is a hollow muscular organ located in the lower part of the abdomen that collects and stores urine from the kidneys until it is passed out of the body. Typically, blood in the urine is the first indication of bladder cancer. However, bladder cancer may also cause a constant urge to urinate, even when the bladder is empty, and urinating more often than usual. These symptoms may also be related to non-cancerous conditions. For this reason, if you experience any of these symptoms, it is important to speak with your doctor.

Robotic-assisted cystectomy is a minimally invasive surgical method for the treatment of bladder cancer. This procedure offers bladder cancer patients the prospect of a more effective surgery and less problematic post-surgical recovery. Minimally-invasive, robotic technology allows surgeons to make smaller incisions, which spare vital, but delicate, nerve and muscle tissue. Following a robotic cystectomy procedure, patients experience a shorter hospital stay, fewer complications, and a faster recovery time.

Kidney Cancer

Each year, more than 50,000 individuals are diagnosed with kidney cancer. For many, kidney cancer is discovered when imaging procedures are performed for other conditions. For some, abdominal pain, back pain or anemia may indicate the presence of kidney cancer.

Robotic-assisted laparoscopic partial nephrectomy delivers the efficacy of open surgery with a safe method for removing small renal tumors, while preserving surrounding kidney tissue. Using a near-infrared camera and a benign tracer that is injected into the blood, surgeons are able to see the blood supply to the kidney and tumor, as well as differentiate cancerous tissue from normal kidney tissue. This allows for better control of the kidney's blood supply, potentially less injury to the area surrounding the kidney, and limits the risk of leaving any tumor behind.

This minimally-invasive technique leaves patients with less discomfort and allows them shorter hospital stays, earlier return to daily activities and smaller incisions.

Upper Urinary Tract Reconstruction

There are benign conditions of the upper urinary tract that may require reconstruction. These conditions include ureteropelvic junction obstruction and ureteral obstruction.

Ureteropelvic Junction (UPJ) Obstruction

Ureteropelvic junction obstruction is a condition where a blockage occurs where the ureter (the tube that drains urine from the kidney to the bladder) and the kidney meet. This blockage may cause urine to build up in the kidneys.

Robotic-assisted laparoscopic pyeloplasty is a minimally-invasive procedure used to repair congenital or acquired narrowing or scarring of the ureteropelvic junction. During pyeloplasty, the obstruction is removed and the urinary tract is then reconstructed. Damage caused by the buildup of fluid pressure is repaired before the ureter and the kidney are sutured back together.

This minimally-invasive procedure incorporates the same efficacy and safety as open surgery with less post-operative pain, a shorter hospital stay, and earlier return to work and daily activities.

Ureteral Obstruction

Ureteral obstruction may be acquired in situations where a blockage in the ureter prevents urine from passing easily from the kidney into the bladder. Additionally, a ureteral obstruction may occur due to the ureter having been damaged during a surgery in the abdomen or after gynecologic surgery.

If the ureter is damaged, it may be possible to reattach the ureter to the bladder with ureteral reimplantation. The Hospital Center's state-of-the-art da Vinci® robotic surgical system allows doctors to perform a precise, minimally invasive procedure through a few tiny incisions with enhanced vision, dexterity and control.
