What is a urologic oncologist?

First: what a urologist is

Urology is the surgical specialty that treats the urinary tract in men and women — kidneys, ureters, bladder and urethra — and the male reproductive system. Becoming a urologist requires medical school first and then a residency of several years in an accredited hospital.

A general urologist is trained to resolve the vast majority of urological problems: infections, stones, prostate enlargement, vasectomy, incontinence and many more. By a wide margin, this is the doctor most people should start with.

What the subspecialty adds

Urologic oncology is a fellowship-level postgraduate programme taken after completing the urology residency. It means additional years, at high-volume referral centres, devoted exclusively to cancer of the urinary tract and male genital organs: prostate, kidney, bladder, testis, penis and adrenal gland.

In Mexico this programme is offered at a very small number of institutions. At present, three hospitals provide it:

• Oncology UMAE, Centro Médico Nacional Siglo XXI (IMSS), endorsed by UNAM — where I trained.
• Instituto Nacional de Cancerología (INCan), Mexico City.
• Hospital Regional de Alta Especialidad del Bajío, León, Guanajuato.

And it is worth being explicit about what does not count. An online course, a diploma programme, a congress or a rotation of a few weeks do not confer the fellowship in urologic oncology. It is granted only by the formal one-year programme at one of those institutions, with university endorsement and official certification. The distinction matters because these terms are used loosely and they do not all mean the same thing.

What changes in practice

The additional training translates into four concrete things, not a label:

• Case volume. The fellowship is taken at centres where urological cancer is daily work. In cancer surgery, how many times a procedure has been performed relates to the outcome.
• Staging. Determining precisely how far a tumour has spread — reading the MRI, the CT, the pathology report — is what defines the treatment. Getting the stage wrong leads to under- or over-treatment.
• Cancer-specific techniques. Nerve-sparing radical prostatectomy, partial nephrectomy to preserve kidney, formal lymph node dissections. These are different operations from those that treat benign disease, even in the same organ.
• Coordination with the wider team. Much of cancer treatment is not surgical. Knowing when the answer is radiotherapy, systemic treatment or surveillance — and not surgery — is part of the training.

Do you need a urologic oncologist for everything?

No, and that deserves to be said plainly. But the question is usually framed backwards, so it is worth setting straight.

A urologic oncologist is still a urologist. They treat exactly what any urologist treats — urinary infections, stones, prostate enlargement, vasectomy, varicocele, erectile dysfunction, check-ups — and, in addition, the whole field of cancer. The subspecialty does not narrow what they treat: it adds to it.

What changes is where that additional training counts. In a urinary infection it adds nothing beyond what any well-trained urologist offers. In a cancer diagnosis it changes the entire conversation: the staging, the options put on the table and the surgical technique.

Hence the practical conclusion: there is no need to go looking for a subspecialist for every complaint, and anyone telling you otherwise is making your care more expensive for no reason. But if you are already with one, you lose nothing; and if something unexpected turns up along the way — a mass on a routine ultrasound, a rising PSA — you are already in the right place and do not have to start over with another doctor.

Seeking one from the outset makes sense when there is a confirmed cancer diagnosis or a reasonable suspicion, when the case is complex or has already been treated, or when you want a second opinion before deciding something irreversible.

How to verify any doctor

This applies to me and to anyone else. In Mexico you can check it yourself, free and in minutes:

• Professional licence and specialty licence. Both are searchable in the SEP national register of professionals. They are two different numbers: one certifies the degree, the other the specialty.
• Current board certification. In urology this is the Mexican National Board of Urology (CONAMEU). The key word is current: certification is renewed periodically and can expire.
• Where the fellowship was done. Ask for the institution, the duration and the university that endorsed it. A specific answer is a good sign; a vague one also tells you something.

A doctor who is uncomfortable with these questions is, in itself, an answer. Asking them is not distrust: it is the minimum reasonable step before placing your health in someone's hands.

My own path, as a concrete example

Medical school at Universidad de Sonora. Urology residency at High-Specialty Medical Unit No. 25 of the IMSS, endorsed by Universidad de Monterrey. Fellowship in Urologic Oncology at the Oncology UMAE of Centro Médico Nacional Siglo XXI, endorsed by UNAM. And a one-year international fellowship in robotic urology at Instituto Israelita Albert Einstein, in São Paulo.

The numbers to check it are in the footer of this page and in every one of my guides. I do not publish them as a formality: I publish them so you can verify them.
