Are consultations and treatments with Dr. Guerra, a Urologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Some newer technologies, medications, or elective procedures (like cosmetic urology or certain non-insured infertility treatments) may not be covered or may require special authorization. It's always recommended to discuss coverage specifics with Dr. Guerra's office or Ontario Health Insurance Plan (OHIP).

Do I need a referral to see Dr. Guerra, a Urologist?

Yes, for most urological consultations and treatments covered by provincial health plans in ON, a referral from your family physician or another specialist is typically required to see a Urologist like Dr. Guerra. This ensures your care is coordinated and appropriate. Some specific services, like vasectomy in certain private clinic settings, might occasionally be accessed directly, but for general urological assessment or provincially insured care, a referral is the standard pathway.

What are the treatment options for an enlarged prostate (BPH)?

Treatment for Benign Prostatic Hyperplasia (BPH) depends on the severity of your symptoms and how much they affect your quality of life. Options range from lifestyle changes and medications to minimally invasive procedures (like UroLift, Rezum) and surgical treatments (such as TURP or laser prostatectomy). Dr. Guerra can discuss the most suitable options for you based on your individual circumstances.

When should I consider seeing a Urologist?

You should consider seeing a Urologist if you experience symptoms such as blood in your urine (hematuria), recurrent urinary tract infections (UTIs), difficulty urinating (hesitancy, weak stream, straining), frequent or urgent need to urinate, urinary incontinence (leakage), pain in the flank, lower abdomen, or groin that might be related to kidney stones, or any concerns related to the male reproductive organs (e.g., testicular pain/lumps, erectile dysfunction, male infertility). Your family doctor can help determine if a referral to a urologist like Dr. Guerra is appropriate.

What is a cystoscopy and why might I need one?

A cystoscopy is a procedure that allows your urologist, such as Dr. Guerra, to look directly inside your bladder and urethra using a thin, lighted instrument called a cystoscope. It might be recommended to investigate symptoms like blood in the urine, frequent UTIs, bladder pain, or difficulty urinating. It can also be used to take biopsies or perform minor treatments. He will explain the procedure and any preparation needed.
