Specialties

Robotic & Open Radical Prostatectomy
As a urologic oncologist, Dr. Feifer has expertise in the surgical management of patients with localized and locally advanced cancer of the prostate. If surgery is a good option for you, Dr. Feifer personalizes the approach to each patient’s cancer, and offers advanced robotic surgery for prostate removal where appropriate and open surgery when is best suits the patient. This personalized approach guarantees that each patient receives the treatment that best suits them, possibly in combination with other therapeutic modalities such as hormonal therapy, radiation, or other forms of prostate cancer treatment. In the decision-making process, statistical prediction tools and a deep focus on quality of life after any form of therapy, are important guides to what choice of therapy might best suit patient’s lifestyle. This comprehensive, compassion approach is what every patient should expect to receive under Dr. feifer’s care.

 

Minimally Invasive Kidney Surgery
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 tumour is removed, and kidney 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.

 

Metastatic & Castrate Resistant Prostate Cancer
Dr. Feifer founded and currently leads the Centre for Advanced and Metastatic Prostate Cancer at Trillium Health partners. This is a unique clinic in Canada, specializing in the comprehensive management of patients with advanced in metastatic prostate cancer, whether castrate sensitive or castrate resistant. Through this clinic, patients will have access to advanced therapeutics such as novel androgen receptor antagonist, Target in therapies for bone health, as well as access to chemotherapy as needed, radiation therapy as needed, and supported by numerous ancillary health professionals including oncology nursing, oncology pharmacy, and drug navigation. A new addition is the comprehensive men’s health program which also includes cardio oncology, sexual health rehabilitation, psycho oncology, and oncology education. There is also access to clinical trials.

 

REZUM ( Minimally Invasive Out Patient Procedure for BPH)
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.

 

High Frequency Ultrasound Ablation (HiFU) for Prostate Cancer
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 personalize assessment of whether high frequency ultrasound is appropriate for your particular cancer case.
