Study Notes
Histology and Growth Patterns
- Characteristic of Benign Prostatic Enlargement (BPE): discrete nodules in the periurethral (Transitional) zone of the prostate gland.
- Benign Prostatic Hyperplasia (BPH) primarily occurs in the central/transitional portion, whereas malignancies typically arise in the prostatic periphery.
Physical Examination and Diagnostics
- Symptomatic men should undergo a Digital Rectal Examination to evaluate prostate size and contour.
- Normal prostate volume ranges from 20-30 mL, while treatment is often indicated for volumes greater than 40 mL, with Finasteride being a common medication.
- Laboratory study recommended for patients with Lower Urinary Tract Symptoms (LUTS) is urinalysis.
- Elevated PSA levels indicate better response to Finasteride.
- Urine cytology is necessary for men at risk of bladder cancer, especially those with a history of tobacco use or hematuria.
Treatment Recommendations
- Watchful waiting is advised for men with mild symptoms (AUA symptom index of 7 or less).
- Finasteride and Dutasteride, 5-alpha reductase inhibitors, function by inhibiting the conversion of testosterone to dihydrotestosterone, suppressing prostate growth.
- 5-alpha reductase inhibitors do not provide immediate symptom relief; benefits take approximately six months to manifest.
- Long-term benefits include reduced risk of acute urinary retention, surgical intervention, and lower incidence of prostate cancer.
- Saw Palmetto plant is an alternative therapy for treating BPH-related LUTS.
- Surgical treatment is warranted when medical therapy fails, especially with conditions like refractory urinary retention and persistent hematuria.
- Transurethral resection of the prostate (TURP) is the benchmark for surgical therapies supported by extensive data.
Symptom Assessment
- International Prostate Symptom Score (IPSS) classifications:
- Severe: 20-35
- Moderate: 8-19
- Mild: 1-7
- IPSS of 21 indicates severe symptoms; an IPSS of 10 indicates moderate symptoms; an IPSS of 7 indicates mild symptoms.
Clinical Guidelines
- Initial evaluation for bothersome LUTS includes medical history, physical examination, IPSS assessment, and urinalysis.
- Post Void Residual (PVR) tests help assess bladder emptying and detect urinary retention or detrusor dysfunction.
- First-line treatments should include lifestyle and behavioral interventions, such as limiting fluid intake before bedtime, reducing caffeine and alcohol, and avoiding irritative foods.
- Kegel exercises and pelvic floor muscle training can address urinary urgency.
- Follow-up after treatment initiation should occur in 4-12 weeks, with IPSS re-evaluation during follow-up.
- For quick onset medications like alpha-blockers, first follow-up can be scheduled as early as four weeks; for longer-acting drugs, it may extend to three to six months.
Medical Therapy
-
Alpha blockers (e.g., Tamsulosin, Alfuzosin, Doxazosin, Silodosin, Terazosin) should be offered for moderate to severe LUTS/BPH.
-
Terazosin and Doxazosin are non-specific alpha-1 blockers approved for both BPH and hypertension.
-
Tamsulosin, Silodosin, and Alfuzosin are less likely to cause orthostatic hypotension and syncope.
-
Tamsulosin has a slightly reduced effect on blood pressure compared to Alfuzosin.
-
Common side effect of alpha-adrenergic receptor blockade includes ejaculatory disorders.

Prostate Cancer Screening Recommendations
- The U.S. Preventive Services Task Force (USPSTF) and the American Academy of Family Physicians recommend against PSA-based screening for prostate cancer.
- PSA-based screening is not advised for men younger than 50 years or older than 70 years.
- Screening is not recommended for men with a life expectancy of less than 10 to 15 years.
- Routine use of PSA tests or digital rectal examinations for prostate cancer screening is not recommended.
- PSA-based screening should not be performed without consideration of life expectancy, risks of testing, overdiagnosis, and overtreatment.
- Men asymptomatic for prostate cancer who are expected to live less than 10 years should not undergo PSA testing for screening.
- Men aged 50-69 years should be informed about the limited potential benefits and substantial harms associated with prostate cancer screening.
Urinary Symptoms Assessment
- The questionnaire assesses various urinary symptoms experienced over the past month.
Incomplete Emptying
- Measures the sensation of not fully emptying the bladder after urination.
- Response options range from "Not at all" to "Almost always."
Frequency
- Evaluates the need to urinate again within two hours after the last urination.
- Scoring reflects the frequency of this occurrence.
Intermittency
- Assesses instances of stopping and starting during urination, indicating potential urinary flow issues.
- Response scale indicates how often this occurs.
Urgency
- Questions the difficulty of postponing urination, indicating urgency levels.
- Responses reflect how challenging it has been to manage the urge to urinate.
Weak Stream
- Investigates occurrences of a weak urinary stream, which can suggest prostate issues in males or other urinary tract concerns.
- Participants score based on frequency from "Not at all" to "Almost always."
Straining
- Focuses on the necessity to push or strain to initiate urination, a possible indicator of obstruction or bladder issues.
- Frequency of this experience is evaluated to understand urgency and strain.
Nocturia
- Measures the number of times individuals wake up at night to urinate, impacting sleep quality and overall health.
- Scoring provides insight into nocturnal urinary patterns.
Total Score
- The total score is calculated based on responses to understand the severity and frequency of urinary symptoms experienced.
