Center for Cryosurgery

The Urologic Institute of New Jersey has established the Center for Cryo-surgical ablation forprostate and kidney cancer.

Our doctors have specialty training in performing these minimally invasive operations in treating localized prostate cancer, recurrent prostate cancer after radiation, and small kidney tumors. Our physicians are ones of a very few urologist in Northern New Jersey involved in the training of others in performing these techniques.
Please call our centers for more information and to find out if these approaches are right for you.

Prostate Cancer Cryosurgery

Renal Cancer Cryosurgery

Cryosurgery or cryo-ablation involves introducing needles that freeze targeted areas of the body to extremely cool temperatures (-190 Celsius) in order to kill cancer cells. The mechanism of this destruction includes disruption of the cell wall, organelles within the cell and prohibiting blood from circulating.

With the advent of newer delivery systems and ultrasound guidance, one can destroy a focal area of tissue/cancer with accuracy up to 2.5 mm. This technology was first described in 1966 but did not gain popularity until the late 1990’s when mobile targeting imaging modalities became more readily available and our access techniques improved. This technology has now been FDA approved and found to be very effective in treating localized prostate cancer as well as select kidney cancers.

Prostate Cancer Cryo-Ablation

Prostate Cancer Cryo-ablation Prostate cancer affects 1 out of 6 men in their lifetime. There are many options to treat prostate cancer. Depending on age, risk factors, medical co-morbidities and if the cancer is localized to the prostate, cryoablation of the prostate can be an excellent treatment choice. It can be used as a first-line treatment for localized prostate cancer or to treat recurrent localized prostate cancer having failed radiation treatment.

As primary treatment for prostate cancer, cryoablation has been found to be equally effective to other standard therapies for low grade prostate cancers. For high-grade cancers, cryotherapy appears to be more efficacious than conformal radiation therapy. In early studies, it appears to be equally effective to surgical removal of the prostate for high grade cancers as well, however, long-term data are lacking.

Renal Cancer Cryo-Ablation

Renal carcinoma is diagnosed in about 32,000 people each year in the US. Renal cancers are usually found incidentally on imaging studies performed for other reasons. If kidney cancer is confined to the kidney, then cure is likely if it is treated. In the past, the only available option for patients with localized kidney cancer had been open radical surgery to remove the entire kidney (radical nephrectomy). Through progress in research, partial nephrectomy was proved to have long-term equivalent cancer control rates. By the late 1990's, urologists began using laparoscopy to remove the entire cancerous kidney. This has resulted in remarkable improvements in how quickly patients have recovered after surgery without compromising their chance of being cured. Laparoscopy also provided access to deliver cryosurgical technology in the treatment of select renal malignancies.

There is now an increasing amount of evidence that targeted cryoablation of small renal cancers is equally efficacious to standard therapies. For tumors that are less than 4 cm in size, the success rate reaches 95% in multiple trials.

This exciting new technology has allows treatment of small renal tumors with minimal morbidity and virtually no blood loss using a laparoscopic approach. This involves making 3 or 4 small keyhole incisions rather than large disfiguring incisions. This approach also allows maximal preservation of renal units without compromising cancer control.
The majority of patients are discharged within 1 to 2 days after undergoing such therapy.
