- Are consultations and treatments with Dr. Dion, a Urologist, covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary consultations with a licensed Urologist like Dr. Dion, as well as most diagnostic tests (e.g., cystoscopy, urodynamics) and provincially insured surgical procedures, are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. 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. Dion's office or Ontario Health Insurance Plan (OHIP).
- Do I need a referral to see Dr. Dion, 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. Dion. 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 is a cystoscopy and why might I need one?
- A cystoscopy is a procedure that allows your urologist, such as Dr. Dr. Dion, 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. She will explain the procedure and any preparation needed.
- What is a PSA test and who should have it?
- The PSA (Prostate-Specific Antigen) test is a blood test primarily used to screen for prostate cancer. PSA is a protein produced by cells of the prostate gland. The decision to have a PSA test is best made in consultation with your doctor, like Dr. Dr. Dion, after discussing the potential benefits, risks, and limitations of screening. Factors such as age, family history of prostate cancer, and ethnicity are often considered. It's not a perfect test, as elevated PSA can also be caused by non-cancerous conditions like BPH or prostatitis.
- What are kidney stones and how does Dr. Dion treat them?
- Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They can cause severe pain when they pass through your urinary tract. Treatment depends on the stone's size, type, and location. Small stones may pass on their own with increased fluid intake and pain medication. Larger stones or those causing significant symptoms might require procedures like Extracorporeal Shock Wave Lithotripsy (ESWL) to break them up, ureteroscopy with laser to remove or break them, or percutaneous nephrolithotomy (PCNL) for very large stones. Dr. Dion will also work with you on strategies to prevent future stones.
- What does a vasectomy involve if performed by Dr. Dion?
- A vasectomy is a minor surgical procedure for permanent male contraception. It involves cutting or blocking the vas deferens, the tubes that carry sperm from the testicles. Dr. Dion would perform this procedure, usually in an outpatient setting under local anesthesia. It's a highly effective form of birth control. It's important to discuss the procedure, potential risks, and the fact that it's considered permanent with Dr. Dion beforehand.
