Digital rectal exam
What is a Digital Rectal Exam?
A digital rectal exam (DRE) is an exam during which a doctor inserts a lubricated, gloved finger into the rectum to feel for any lumps or other abnormalities such as tumors. This exam is primarily used to check the prostate in men, but can also be used to check for other conditions such as hemorrhoids, anal fissures, or anal abscesses. It is also used to confirm a diagnosis of certain gastrointestinal diseases, such as irritable bowel syndrome.
Purpose of a Digital Rectal Exam
Your doctor may order a DRE to check for any abnormal changes in your rectum or to feel for any enlarged prostate. An enlarged prostate, also known as prostatic hyperplasia, is a common condition in men older than 50. The most common reason for a DRE is to perform a prostate exam, which looks for signs of prostate cancer.
Many men experience an enlarged prostate due to certain medications, such as finasteride, or simply due to aging. If your doctor notices an enlarged prostate during a DRE, they may recommend further testing or begin treatment.
How to Prepare for a Digital Rectal Exam
The preparation for a DRE is relatively simple. You may want to clean your anus before the exam, but this is not necessary. Wear comfortable clothing and try to relax. Your doctor may also suggest that you take a mild pain reliever, such as ibuprofen, before the exam.
How a Digital Rectal Exam is Performed
A DRE usually takes place in a private room. The doctor will ask you to stand with your feet apart and bend over. They will then insert a lubricated, gloved finger into your rectum and feel for any lumps or abnormal changes. During the exam, your doctor may ask you to bear down slightly, as this can make it easier for them to feel any irregularities. The exam usually lasts just a few minutes.
Types Of Digital Rectal Exam
There are two types of digital rectal exams:
- Standard DRE: The doctor will insert a lubricated, gloved finger into your rectum and feel for any lumps or abnormal changes.
- Transrectal Ultrasound (TRUS): TRUS is a type of imaging exam that uses sound waves to create an image of the prostate. The doctor will insert a small probe with an ultrasound transducer attached to it into the rectum. The probe can move back and forth to create an image of the prostate.
Risks of Digital Rectal Exam
A DRE is generally safe, but there are some risks associated with it. These can include temporary pain or discomfort, the risk of infection, and the risk of tissue tearing, although these are rare. Your doctor will take precautions to minimize any risks.
Why a Digital Rectal Exam is Performed?
Your doctor may recommend a DRE to feel for lumps or changes in the rectum or to perform a prostate exam. They may also recommend it to confirm a diagnosis of a gastrointestinal disease.
When a Digital Rectal Exam is Performed?
Your doctor may recommend a DRE if they suspect any abnormalities in the rectum or prostate, or if you are experiencing any symptoms of a gastrointestinal disease. A DRE is usually performed annually after the age of 50, or sooner if you are at an increased risk of prostate cancer.
