Diagnosis Of Benign Prostatic Hyperplasia
Your doctor will consider your symptoms and carry out some tests to rule out the diseases that mimic the symptoms of benign prostate hyperplasia.
1. Digital rectal exam
Your prostate can be felt through the anus. Your doctor will smear some topical anaesthesia (numbing gel) onto your anal passage. Then the doctor will insert a gloved hand into the rectum to feel the prostate's shape, thickness, and size. This will give them an idea if your prostate has an average size or is more prominent than usual.
2. Cystoscopy
This procedure allows a healthcare provider to examine the lining of your bladder and urethral tube. A hollow tube called a cystoscope that has a lens will be inserted inside your urethra. Slowly the doctor will advance the cystoscope inside your bladder. This procedure usually doesn't hurt but can cause some discomfort. You may feel that you need to pee during the process, but it only lasts for a few minutes.
3. Ultrasound
Ultrasound has become the standard first-line investigation after the urologist's finger. Ultrasound of the kidneys and urinary bladder (USG KUB) is done routinely to evaluate size and volume of prostate gland.
4. Intravenous pyelogram (IVP)
An intravenous pyelogram (IVP) is a type of x-ray that provides images of the urinary tract. During an IVP, a health care provider will inject one of your veins with a substance called contrast dye. The dye travels through your bloodstream and into your urinary tract. It helps in detection of an enlarged prostate. Due to availability of better alternatives, IVP is not commonly used these days.
5. Urine tests
Your doctor may ask for a urine test. This will help them rule out any infection or other urinary conditions that cause similar symptoms.
Prostate-specific antigen is a compound released by your prostate. When you have an enlarged prostate, your levels of PSA will also increase. It helps detect prostate cancer, but it's not perfect and doesn't detect all prostate cancers. Your PSA levels can be elevated due to recent procedures, surgeries or infections.
7. Urinary flow test
This test measures your urine flow. You will be asked to urinate into a receptacle that is attached to a machine. This machine will measure the strength and amount of your urine flow and determine, if your condition is improving or worsening over time.
8. Postvoid residual volume test
This test evaluates if you can fully empty your bladder while urinating. The test can be done through ultrasound or by inserting a catheter into your bladder after you finish urinating. This will allow a healthcare provider to measure how much urine is left in your bladder.
9. 24-hour voiding diary
Your doctor may ask you to maintain a record of the frequency and amount of urine you pass. This is especially helpful if more than one-third of your daily urine output occurs during the night.
Transrectal ultrasound is an ultrasound probe inserted into the rectum to measure and evaluate your prostate health. The probe sends and receives sound waves through the wall of the rectum into the prostate gland which is situated right in front of the rectum. Your doctor can suggest a prostate biopsy using a transrectal biopsy. A needle will be guided inside the rectum to take tissue samples of the prostate. Examining the tissue will help the doctor evaluate if you have prostate cancer or not.
11. Urodynamic and pressure flow studies
This test allows doctors to measure and determine how well your bladder muscles are functioning. Your doctor will insert a catheter inside your urethra and into your bladder. Water or air is slowly injected into the bladder, which allows for the evaluation of muscle functioning.
