Diagnosis of Benign Prostatic Hyperplasia
When a doctor evaluates someone for possible BPH, the evaluation typically consists of a thorough medical history, urinalysis (an examination of the urinary sediment), a physical examination (including a digital rectal exam or DRE), and use of the AUA BPH Symptom Score Index.
AUA BPH Symptom Score Index-
The American Urological Association (AUA) has developed an AUA BPH Symptom Score Index to help assess the severity of BPH symptoms, ranging from mild to severe.
A physical examination helps the doctor evaluate the patient’s general health. Digital Rectal Examination (DRE) is usually the first test done. The doctor assesses the size and condition of the prostate gland by inserting a gloved finger into the rectum and feeling the part of the prostate next to the rectum.
Urine investigations like urine culture are done to rule out urinary tract infection. A measurement of post-void residual volume (PVR) helps determine the amount of urine left in the bladder after urinating
PSA (Prostate specific antigen) blood test is used to detect abnormally high levels of a protein substance in the blood that may indicate prostate cancer.
Uroflometry / Urine Flow Study- The doctor may ask the patient to urinate into a special device that measures how quickly the urine is flowing. A reduced urine flow often suggests BPH.
Cystoscopy- Cystoscopy allows the doctor to determine the size of the gland and identify the location and degree of the obstruction.
Ultrasound of the kidney or the prostate is done to view the enlargement.
Urodynamic pressure-flow study- It tests the pressures inside the bladder during urination.
