What are the symptoms of BPH?
BPH (Benign Prostatic Hyperplasia) causes a group of symptoms called Lower Urinary Tract Symptoms (LUTS). These are divided into three categories:
Storage symptoms (bladder filling problems):
- Frequency: Needing to urinate more than 8 times per day.
- Nocturia: Waking up 2 or more times at night to urinate.
- Urgency: Sudden, strong need to urinate that is hard to delay.
- Urge incontinence: Leaking urine before reaching the toilet (less common in early BPH).
Voiding symptoms (bladder emptying problems):
- Weak urinary stream: Urine comes out slowly or dribbles.
- Hesitancy: Difficulty starting urination (waiting >10-15 seconds).
- Straining: Pushing to empty the bladder.
- Intermittency: Urine stream stops and starts.
- Terminal dribbling: Leaking after finishing urination.
Post-voiding symptoms:
- Incomplete emptying: Feeling that the bladder is not fully empty after urinating.
- Post-void dribbling: Leaking minutes after urinating.
How common are BPH symptoms by age?
BPH symptoms become increasingly common with age:
- 40-49 years: 10-20% have moderate-severe symptoms
- 50-59 years: 30-50% have moderate-severe symptoms
- 60-69 years: 50-60% have moderate-severe symptoms
- 70-79 years: 70-80% have moderate-severe symptoms
- 80+ years: >80% have some symptoms
However, symptom severity does not always correlate with prostate size. Some men with very large prostates have mild symptoms, while others with moderately enlarged prostates have severe symptoms.
What is the IPSS score?
The International Prostate Symptom Score (IPSS) is a validated, standardised questionnaire used worldwide to assess the severity of BPH symptoms. It is the most important tool for:
- Initial assessment of symptom severity
- Tracking symptom progression over time
- Evaluating response to treatment
- Deciding when to start or escalate therapy
IPSS questionnaire – the 7 questions
The IPSS asks 7 questions about urinary symptoms over the past month. Each question is scored 0-5 based on frequency:
- 0 = Not at all
- 1 = Less than 1 time in 5
- 2 = Less than half the time
- 3 = About half the time
- 4 = More than half the time
- 5 = Almost always
- 0 = None
- 1 = 1 time
- 2 = 2 times
- 3 = 3 times
- 4 = 4 times
- 5 = 5 or more times
How to calculate your IPSS score
Add the scores from all 7 questions. The total IPSS score ranges from 0 to 35.
- Each of questions 1-6: 0-5 points
- Question 7 (nocturia): 0-5 points
- Total = Sum of all 7 questions
Example: If a patient scores: Q1=2, Q2=3, Q3=1, Q4=2, Q5=3, Q6=1, Q7=2 → Total IPSS = 14
IPSS severity categories – mild, moderate, severe
Symptom severity is classified as follows:
- Mild (0-7): Symptoms are mild and usually do not require treatment. Watchful waiting with lifestyle changes is appropriate.
- Moderate (8-19): Symptoms are bothersome. Treatment options (medications, minimally invasive procedures) should be discussed.
- Severe (20-35): Symptoms significantly impact quality of life. Active treatment is usually recommended, including surgery for refractory cases.
Quality of life (QoL) score – the bother index
The IPSS also includes a single Quality of Life (QoL) question (also called the "bother score"):
"If you were to spend the rest of your life with your urinary condition just the way it is now, how would you feel?"
- 0 = Delighted
- 1 = Pleased
- 2 = Mostly satisfied
- 3 = Mixed (about equally satisfied and dissatisfied)
- 4 = Mostly dissatisfied
- 5 = Unhappy
- 6 = Terrible
A QoL score of ≥4 (mostly dissatisfied or worse) is often used as a threshold for recommending treatment, even if the IPSS is only in the moderate range.
When to see a doctor based on IPSS
- IPSS 0-7 (Mild): No immediate need to see a doctor unless symptoms bother you. Discuss at annual physical.
- IPSS 8-19 (Moderate): Schedule a urology appointment. Discuss treatment options (medications, lifestyle changes, minimally invasive procedures).
- IPSS 20-35 (Severe): See a urologist soon. Symptoms significantly affect quality of life. Treatment is usually recommended.
- Any IPSS with QoL ≥4: Even if IPSS is moderate, the bother score indicates treatment is warranted.
Other symptoms not in IPSS
While the IPSS covers the most common urinary symptoms, other symptoms may indicate complications or other conditions:
- Pain with urination (dysuria): Not typical of BPH – suggests prostatitis, UTI, or urethral stricture.
- Blood in urine (hematuria): Can occur with BPH (from engorged vessels) but always requires evaluation to rule out cancer.
- Blood in semen (haematospermia): More common with prostatitis or after prostate biopsy – not typical of BPH alone.
- Pelvic or perineal pain: Suggests prostatitis, not BPH.
- Erectile dysfunction: BPH does not cause ED, but some BPH medications (5-ARIs) may contribute.
Tracking symptoms over time
The IPSS is not just a one-time tool. It should be used to monitor symptom progression and treatment response:
- Before treatment: Baseline IPSS to establish severity.
- 3-6 months after starting medication: Repeat IPSS to assess response. A decrease of ≥3 points is clinically meaningful.
- After minimally invasive procedure or surgery: Repeat IPSS at 3, 6, and 12 months to document improvement.
- Annual monitoring: For men on watchful waiting, annual IPSS helps detect progression.
Many urology clinics provide IPSS forms at each visit to track symptoms objectively.
Interactive FAQ – BPH symptoms and IPSS score
The most common symptoms are weak urinary stream, frequent urination (day and night), urgency, hesitancy, and feeling of incomplete emptying.
IPSS 0-7 is considered mild (minimal symptoms). Many men over 50 have scores in this range without significant bother.
Generally IPSS ≥8 (moderate) with bothersome symptoms. However, even mild symptoms (IPSS 0-7) can be treated if they affect quality of life.
The IPSS is a validated, reliable tool that correlates well with objective measures like urine flow rate. It is the gold standard for symptom assessment.
No – IPSS measures symptoms, not cancer. BPH and cancer can cause similar symptoms. PSA and DRE are needed to assess cancer risk.
IPSS measures symptom frequency/severity (0-35). QoL measures how bothered you are by symptoms (0-6). Both are important for treatment decisions.
BPH itself does not cause pain. Pain suggests prostatitis, urinary retention, or another condition. See a doctor if you have pelvic pain.
Annually for watchful waiting, 3-6 months after starting medication, and 3-12 months after procedures/surgery.
No – nocturia can also be caused by overactive bladder, diabetes, sleep apnea, excessive evening fluid intake, or medications (diuretics).
