Tower Urology – Los Angeles

The philosophy of Tower Urology is simply stated: EXCELLENCE.

Each physician in the Tower Urology not only has completed a full training program in urologic surgery, but also has augmented their basic training in additional areas of urologic science.

The physicians in TU work both individually and as a team, consulting frequently in the care and management of our patients, as well as acting cooperatively in the operating theater. TU physicians are involved in all aspects of urologic disease and management. Although a patient usually identifies with a single doctor in TU, that patient can be certain that his /her urologic care and well-being are the concern and the responsibility of all members of the Tower Urology team. This team approach is most unusual. It has been developed over the past twenty years and is currently considered to be a role model for all such urologic groups worldwide.

All of the physicians in the group continuously upgrade their areas of interest and are conversant with the latest techniques available. In addition to the physicians in Tower Urology, there is a staff of health professionals including nurses, a physician’s assistant, laboratory technicians, x-ray technicians and supporting staff, all of whom are dedicated to deliver excellence in urologic care.

I am writing from a most unusual “position.”  I am an urologist who has been in practice for 38 years with recently diagnosed prostate cancer. I envision a 4 part “installment” of communication related to my personal battle with this disease. These four “installments” will cover: 1) preoperative considerations and decision making (see below), 2) my experience with the surgery to remove the prostate (robotic radical prostatectomy performed early February 2019 – see below), 3) my recovery within the first few months after surgery (see below), and 4) long-term issues after initial treatment. I truly hope that my experience may help other men who are dealing with a recent diagnosis of prostate cancer.


When patients learn they have prostate cancer, they often fear that impotence is inevitable. In almost all cases, fear of impotence is totally unwarranted. It is true that the old surgical cure for prostate cancer left 60 to 80 percent of patients impotent since surgery damaged the vital nerve bundles that make erection possible. Today, however, the majority of men who undergo treatment for prostate cancer will still be able to enjoy an active sex life after treatment. Here’s how you can have a terrific sex life after prostate cancer.


Prostate cancer is one of the most serious health problems in the global community. It is the most common male malignancy and has touched almost every family. Recently, the rate of prostate cancer among men caught up to that of lung cancer. More than two hundred thousand cases are detected each year in the United States alone. About one in every six men in the United States will develop the disease during his lifetime.


Thank you for your thoughtful and successful treatment of my disease. Not only for your medical skills but also your kind and patient manner. It appears your efforts are a success. I look forward to my two daughters’ weddings and my son’s graduation from MIT.

Tower Urology is proud to introduce a powerful new MR solution for analysis, planning and targeted biopsy of the prostate. This complete clinical MR solution for the prostate combines DynaCAD for Prostate with the UroNav fusion biopsy system – a combined solution which offers a truly new imaging option for many patients with elevated and/or rising PSA levels.

Targeted MR/ultrasound biopsy is poised to become the new standard in prostate care, and Tower Urology is pleased to be one of the first urology groups in the area to offer this powerful solution to our patients. UroNav fuses pre-biopsy MR images of the prostate with ultrasound-guided biopsy images in real time, for excellent delineation of the prostate and suspicious lesions.
