Dr. Feifer is known for specializing in minimally invasive approaches to kidney cancer. In general, most kidney cancer is found incidentally, and there has been a dramatic improvement in our ability to prevent total kidney loss while maximizing the cancer benefit of removing tumors. Dr. Feifer specializes in extended partial nephrectomy, performed in a minimally invasive laparoscopic fashion, where the tumor is removed, and the kidney is reconstructed. Dr. Feifer specializes in hard-to-reach tumors, which require much experience technically, as well as having a deep understanding of kidney cancer behavior.

Rezūm Water Vapor Therapy is a non-surgical treatment that uses the natural energy stored in water vapor, or steam, to remove excess prostate tissue that is pressing on the urethra. Dr. Feifer has one of a select few urologists in the GTA who has performed many of these procedures with great success since this technology was approved in Canada. The procedure is brief, does not require anything more than a twilight anesthetic, requires no hospital stay, and is entirely minimally invasive. Because of the initial swelling caused by the steam, the catheter is inserted which will remain for 2 to 5 days.

Certain patients with a new diagnosis of locally contain prostate cancer may be a candidate for high frequency ultrasound image guided ablation of the cancer. High intensity focussed ultrasound is a prostate cancer treatment performed by Dr. Feifer that uses a highly focussed ultrasound to pinpoint, heat, and kill prostate cancer cells using MRI guidance. Unlike radiation and surgery, who is relatively non-invasive and requires no incisions, is an outpatient procedure, and works to target the cancer itself and leave the prostate around the cancer which is normal alone. The impact of this treatment is less perturbation on urinary or sexual side effects after prostate cancer therapy. This is not a treatment for everyone, and your discussion with Dr. Feifer will involve a detailed personalized assessment of whether high frequency ultrasound is appropriate for your particular cancer case.
