What are the signs and symptoms of prostatitis in men?

Signs and Symptoms of Prostatitis in Men

Prostatitis presents with distinct clinical patterns depending on whether it is acute bacterial, chronic bacterial, or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), with acute bacterial prostatitis typically manifesting as abrupt onset of febrile urinary tract infection symptoms, while CP/CPPS presents as persistent pelvic pain for at least 3 months accompanied by urinary symptoms. 1, 2

Acute Bacterial Prostatitis

Acute bacterial prostatitis presents with:

• Fever and chills as hallmark systemic symptoms 2
• Abrupt onset of febrile UTI symptoms 1
• Lower urinary tract symptoms including dysuria, urinary frequency, and urgency 1
• Pelvic discomfort and suprapubic pain 3
• Acute hematuria may occur 1
• Costovertebral angle tenderness or flank pain 1

Chronic Bacterial Prostatitis

Chronic bacterial prostatitis manifests with:

• Recurrent urinary tract infections from the same bacterial strain 2
• More persistent, less acute symptoms compared to acute prostatitis 1
• Irritative voiding symptoms (frequency, urgency) 4
• Obstructive voiding symptoms 4

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS)

CP/CPPS is diagnosed when pelvic pain or discomfort persists for at least 3 months and is associated with urinary symptoms, after excluding infection, cancer, obstruction, or retention 2, 5.

Pain Locations and Characteristics

Pain in CP/CPPS occurs in multiple pelvic and perineal locations:

• Perineal pain or fullness (52.1% of patients) 4, 3
• Scrotal pain (44.8% of patients) 4
• Lumbar/lower back pain (35.4% of patients, more prevalent in older patients) 4, 3
• Penile pain (tip of penis) 6, 3
• Testicular pain 6, 3
• Pubic or bladder area pain 6
• Rectal pain 3
• Post-void pain 3
• Dysuria (painful urination) 6, 3

Urinary Symptoms

Lower urinary tract symptoms are prominent in CP/CPPS:

• Urinary urgency and frequency (89% of patients) 3
• Irritative voiding symptoms 4
• Suprapubic discomfort 7

Sexual Dysfunction

Sexual dysfunction is the most common symptom category in men with prostatic inflammation, particularly affecting younger men in their third and fourth decades 4:

• Ejaculatory disorders are the most frequent sexual complaint (67.7% of patients) 4
• Pain during or after ejaculation 7, 3
• Pain with sexual intercourse (75% of patients) 3
• Erectile dysfunction (30.2% of patients) 4, 7
• Decreased libido (22.9% of patients) 4
• Hemospermia (blood in semen) (20.8% of patients) 4

Prevalence and Population Impact

• Approximately 9.3% of men experience prostatitis in their lifetime 2
• Population-based studies indicate approximately 1 in 9 men have prostatitis-like symptoms 6
• The prevalence of CP/CPPS symptoms ranges from 5.9% to 7.5% depending on diagnostic criteria used 6
• Prostatic inflammation is most commonly seen in men of the third and fourth decades of life 4

Clinical Pitfalls

Lower urinary tract symptoms and lumbar pain are more prevalent in older patients with prostatic inflammation 4. When evaluating men with complicated UTIs, prostatitis cannot be excluded in male patients, which influences treatment duration (14 days rather than 7 days) 1. The wide variety of pain locations throughout the pelvis means clinicians must inquire specifically about each potential site rather than assuming pain is localized to the prostate region 3, 5.
