The Digital Rectal Exam (DRE) remains a fundamental part of the clinical assessment for prostate health in the UK. Despite advancements in medical imaging and blood testing, the physical examination provides immediate, hands-on information that technology cannot always replicate. It is a standard procedure used by GPs and urologists to evaluate the size, shape, and texture of the prostate gland, helping to distinguish between benign enlargement, inflammation, and potential malignancy.

Is the DRE still a relevant tool for prostate health?
The Digital Rectal Exam is very much still in use and remains a cornerstone of the prostate diagnostic pathway. While blood tests like the PSA (Prostate-Specific Antigen) are excellent at detecting chemical changes, they cannot ‘feel’ the physical state of the gland. A DRE allows a clinician to detect hard lumps, irregularities, or asymmetries that a blood test might miss. In fact, some aggressive forms of prostate cancer do not raise PSA levels significantly but can be detected through a physical exam.
Modern clinical guidance from NICE and the NHS suggests that a DRE should be performed for:
- Men presenting with lower urinary tract symptoms (LUTS).
- Men who have requested a PSA test for screening purposes.
- Investigating symptoms that might suggest prostatitis or advanced prostate issues.
- Routine monitoring of patients with a known diagnosis of BPH.
What a clinician looks for during the exam
The DRE provides immediate feedback about the physical characteristics of the prostate. The gland sits just in front of the rectal wall, making it accessible for a brief, manual assessment.
| Characteristic | What is ‘Normal’ or ‘Benign’ | Concerning Findings |
| Size | Small (walnut-sized) or smooth, symmetrical enlargement. | Significant enlargement that suggests obstruction. |
| Texture | Soft, elastic, and smooth (similar to the tip of a nose). | Hard, stony, or ‘nodular’ (lumpy) areas. |
| Symmetry | Both sides (lobes) feel equal in shape and size. | One side feeling significantly different or distorted. |
| Sensitivity | No pain, though a brief urge to urinate is common. | Significant tenderness or pain, often indicating prostatitis. |
How the procedure is performed
Understanding the process can help alleviate the anxiety many men feel about the DRE. The exam is very brief, usually lasting less than 60 seconds.
Preparation:
You will be asked to undress from the waist down behind a screen. You will typically be asked to lie on your left side on an examination couch with your knees drawn up toward your chest. A chaperone is often offered or can be requested for your comfort.
The Exam:
The clinician will put on a pair of gloves and apply a water-based lubricant to their index finger. They will then gently insert the finger into the rectum. You may feel a sensation of pressure or a brief urge to urinate as the finger passes the prostate.
Afterwards:
The clinician removes their finger, and you are given privacy to dress. They will then discuss the findings with you immediately. While the exam may be slightly awkward or uncomfortable, it should not be painful.
Triggers for a DRE referral
A GP will usually suggest a DRE based on specific triggers or patient requests. It is rarely done as a completely isolated test without a clinical context.
- Urinary Changes: If you report a weak stream, hesitancy, or waking up multiple times at night to urinate.
- Raised PSA: If a blood test comes back with a higher-than-expected PSA level, a DRE is the next logical step to check the gland’s physical state.
- Pelvic Pain: Pain in the lower abdomen, groin, or rectum can be a trigger to check for inflammation (prostatitis).
- Patient Request: Men over 50 who are concerned about their prostate health often receive a DRE as part of a comprehensive check-up.
Differentiation: DRE vs. PSA vs. MRI
It is important to understand how the DRE fits into the wider diagnostic toolkit. No single test is perfect, which is why they are often used together.
DRE vs. PSA Test:
The PSA test is highly sensitive but not very specific it can be raised by many non-cancerous things. The DRE is less sensitive for early-stage small tumours but can identify ‘PSA-negative’ cancers and provide an immediate assessment of the size of a benign enlargement.
DRE vs. MRI:
In recent years, many men in the UK are referred for a multiparametric MRI scan if their PSA or DRE results are concerning. An MRI provides a detailed 3D image of the gland. However, the DRE is still used first because it is instant, cost-effective, and helps the GP decide if a specialist referral for an MRI is even necessary.
My final conclusion
The Digital Rectal Exam remains an essential and highly effective tool in the assessment of prostate health. While technology like MRI and PSA testing has advanced, the hands-on information provided by a DRE is invaluable for a GP in making an accurate diagnosis. It is a quick, safe, and routine procedure that plays a vital role in identifying issues early. If you have concerns about your urinary health, a DRE is a standard part of the care you should expect.
If you experience severe, sudden, or worsening symptoms, or a complete inability to pass urine, call 999 immediately.
Is a DRE painful?
For most men, it is not painful; it is more described as a brief feeling of pressure or an odd sensation of needing to urinate.
Can I skip the DRE and just have a blood test?
You can, but it is not recommended. Some prostate issues do not change your blood chemistry but can be felt physically, so having both provides the best accuracy.
Who performs the DRE?
In a GP surgery, it is usually performed by a doctor or a specialist nurse practitioner.
Does a normal DRE mean I don’t have cancer?
Not necessarily; a DRE can only feel the back and sides of the prostate. This is why it is used alongside the PSA test and sometimes an MRI for a full picture.
What if I have haemorrhoids?
You should tell the clinician beforehand. They will be extra gentle, but having haemorrhoids usually doesn’t prevent the exam from being carried out.
How often should I have a DRE?
There is no set schedule for routine DREs for all men, but if you have urinary symptoms or are over 50, it may be discussed during your annual or biennial check-up.
