Getting up 4 times a night to go pee. Standing at the toilet for a minute until the urine begins to flow. A stream so weak it barely makes it through the bowl. The constant feeling that the bladder is never emptied. If this sounds familiar, you almost certainly have an enlarged prostate and you are far from alone.
Benign Prostatic Hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, affecting more than half of all men above the age of 60 and over 80% of men above 80 years in India. It’s one of the most common reasons men visit a urologist. BPH is not cancer, and it doesn’t cause cancer. But it can affect quality of life, including sleep, work, travel, relationships and confidence.
BPH – Benign Prostatic Hyperplasia Let’s break this down:
“Benign”, Not cancer. BPH is not cancer . It is not life threatening . It does not spread . That is the first and most important thing to realize.
“Prostatic” – Refers to the prostate gland, which is shaped like a walnut and is situated just below the bladder, encircling the urethra.
“Hyperplasia”: An abnormal increase in the number of cells, resulting in an increase of the volume of the gland.
BPH : The inner zone of the prostate ( transition zone , around the urethra ) slowly enlarges in a non-cancerous way . As this inner zone expands it compresses the urethra from all sides like squeezing a tube from the outside and gradually narrowing the channel through which urine must pass. The bladder has to work harder and harder to push urine through the narrowing and eventually, from the sustained effort, secondary changes (thickened wall, overactivity) develop.
BPH is not a disease in the traditional sense , it is a natural , age-related change in the prostate that occurs in virtually all aging men to some degree . What determines whether it requires treatment is not just the size of the prostate, but how significantly it is impacting the individual man’s urinary function and quality of life.
The prostate enlarges in response to male hormones, especially dihydrotestosterone (DHT), which is formed from testosterone by the enzyme 5-alpha-reductase in the prostate cells. As men get older the balance of androgens and oestrogens in the body changes slowly, with relatively higher oestrogen levels stimulating prostate growth. This hormonal environment, combined with age-related changes in the regulation of growth and death of prostate cells, leads to the progressive enlargement that characterizes BPH. The transition zone is about 5 grams in a young man, but in severe BPH, it can grow to 50, 100 or even 200 grams or more thereby gradually compressing the central urethral channel.
Ultrasound ( transrectal or transabdominal ) measures prostate size . The seriousness of BPH is graded by prostate volume (size) and by symptom severity (IPSS score). A simplified grading structure is here:
Grade | Prostate Volume | Typical Characteristics |
Grade I (Mild) | 20–30 grams (normal to mild enlargement) | Minimal urinary symptoms; often manageable with lifestyle modification or alpha-blockers |
Grade II (Moderate) | 30–50 grams | Moderate obstructive and storage symptoms; typically managed with medication or minimally invasive procedures |
Grade III (Significant) | 50–80 grams | Significant obstruction; medications often insufficient; procedural intervention (TURP, UroLift, Rezum) usually needed |
Grade IV (Severe) | Above 80 grams | Large prostate with significant obstruction; laser enucleation (HoLEP/ThuFLEP) is the most appropriate and durable treatment |
BPH causes two types of lower urinary tract symptoms; obstructive symptoms (caused by mechanical compression of the urethra) and storage symptoms (caused by secondary overactivity of the bladder). There are plenty of men who have a bit of each:
Weak or Slow Urine Stream
The most common symptom of BPH is a progressive weakening of the stream, causing men to stand longer at the toilet and feel the flow was insufficient . Uroflowmetry objectively confirms and quantifies the decrease.
Being woken up out of sleep two, three, four or more times in the night to pass urine. Nocturia in BPH is caused by incomplete bladder emptying (bladder refills quickly) and secondary bladder overactivity. It is the most serious symptom in terms of quality of life.
Delay of 10 to 60 or more seconds from the urge to urinate to the beginning of flow. The bladder pressure must be high enough to overcome the prostatic obstruction prior to the initiation of urination. Many men say they have to push or strain to start urinating.
A constant urge to urinate, with the sensation that the bladder is not empty. Confirmed by post-void residual ultrasound (PVR) A clinically significant PVR is greater than 100 to 150 ml, indicating incomplete bladder emptying.
A strong and urgent feeling to urinate that is difficult to postpone , and may lead to urgency incontinence ( leaking before arriving at the toilet ) . Chronic obstruction causing secondary bladder change from detrusor overactivity.
BPH can also cause haematuria (blood in the urine), particularly from dilated blood vessels on the surface of the enlarged prostate that rupture with the increased voiding pressure. Any hematuria should be properly investigated before concluding that it is due to BPH and excluding bladder cancer and kidney pathology.
BPH develops from a combination of age-related hormonal changes and genetic predisposition , with lifestyle factors modifying the severity of the condition:
Age-Related Hormonal Changes in Men
The International Prostate Symptom Score (IPSS) is a validated and standardized questionnaire used worldwide to objectively measure the severity of lower urinary tract symptoms associated with BPH. It is the most critical clinical tool for grading severity of BPH, guiding therapy selection, and following the response to therapy over time.
The IPSS is comprised of 7 symptom questions, each scored from 0 (not at all) to 5 (almost always), and one quality of life question:
The sum of the 7 symptom scores gives a total IPSS score between 0 and 35. The quality-of-life question was “If you had to live with your urinary condition as it is now for the rest of your life, how would you feel?” and scored from 0 (delighted) to 6 (terrible).
IPSS 0-7, Mild Symptoms Symptoms are present, but minimal, with little or no interference in daily activities. Most men in this category do not need active treatment. Management is lifestyle modification (decreasing evening fluid intake, limiting caffeine and alcohol, timed voiding, bladder training) with watchful waiting and yearly reassessment of IPSS. Poor quality-of-life score with a low IPSS may be an indication for medication.
IPSS 8-19, Moderate Symptoms: Symptoms are causing significant problems with daily activities, sleep and quality of life. In this group, medical therapy (alpha-blockers, 5-alpha-reductase inhibitors, or combination therapy) is most commonly started. Patients who do not respond well to medication or who prefer a procedural solution will be assessed for minimally invasive treatment with UroLift, iTind, Rezum or TURP, depending on the size and anatomy of the prostate.
IPSS 20–35 , Severe Symptoms: Symptoms severely affect quality of life often to the point that daily activities, work, travel and sleep are significantly disrupted. Most patients in this group are candidates for surgical or procedural intervention regardless of a trial of medication. The most widely recommended procedures for severe BPH are HoLEP, ThuFLEP, or TURP. Dr Vikas Singh treats each patient of severe BPH on case to case basis in order to provide the most suitable treatment. He considers the size of the prostate, result of uroflowmetry, post void residual and the preference of the patient.
IPSS Score | Category | Typical Management | Urgency of Action |
0–7 | Mild | Lifestyle changes + watchful waiting | Low , annual review |
8–19 | Moderate | Alpha-blockers / 5-ARI medication; consider procedure if inadequate response | Moderate , start treatment |
20–35 | Severe | Procedural or surgical treatment (TURP, HoLEP, UroLift etc.) | High , prompt evaluation |
Any + Retention | Emergency | Catheterisation + urgent prostate procedure | Immediate |
No, BPH (Benign Prostatic Hyperplasia) is an enlarged prostate that isn’t cancerous. It does not cause prostate cancer, does not increase the risk of developing prostate cancer, and is not a precursor to prostate cancer. BPH grows in the inner transition zone of the prostate; prostate cancer typically develops in the outer peripheral zone. Both conditions, however, can be seen in the same man. This is why a PSA test is important as part of the evaluation of any man with urinary symptoms, even if he has a diagnosis of BPH.
Yes. If left untreated, the prostate continues to grow slowly with age in most men at an average rate of about 1 to 2% per year in volume. But the speed at which that growth occurs is wildly different from person to person. If left untreated, BPH can progress over years from mild to moderate to severe symptoms. In some men, BPH can lead to complications such as acute urinary retention, bladder stones, recurrent UTIs, and bladder damage. This is the reason why all men with mild BPH should be reviewed annually, to monitor for progression and intervene before complications arise.
Not always. Medications (alpha-blockers, 5-alpha-reductase inhibitors) or lifestyle changes can be very effective in treating many men with mild to moderate BPH. Surgery or a minimally invasive procedure is advised for patients who have severe symptoms (IPSS greater than 20), who do not get adequate relief from medications, who have acute urinary retention, whose bladder is being damaged from chronic incomplete emptying (high post-void residual), or who prefer definitive one-time treatment rather than daily lifelong medication. Dr. Vikas Singh will give you honest advice whether your situation needs intervention.
UroLift and iTind are the fastest functional recovery, most UroLift patients are back to light work within 3-5 days and iTind patients within 24-48 hours of device removal. Patients undergoing HoLEP and ThuFLEP generally resume light work within 1 to 2 weeks. Rezum patients return to light work in 1-2 weeks. Traditional TURP takes 2-4 weeks. But the correct procedure is not necessarily the one with the quickest recovery time, it is the one that best matches your prostate anatomy, size and symptom severity.
Yes, if you leave it untreated for a long time. If the prostate obstruction is so severe that it prevents adequate bladder emptying, the back pressure from chronic high bladder volumes can eventually affect the kidneys causing hydronephrosis (kidney swelling) and progressive loss of kidney function. This is called obstructive nephrophathy. This is rare in men who seek early treatment, but men with a very large post-void residual (greater than 300 to 400ml), recurrent infections or bilateral hydronephrosis on ultrasound require urgent prostate treatment to maintain kidney function.
