Summary

An elevated PSA does not automatically mean prostate cancer.

It can be elevated in different situations, including:

prostate cancer;
benign prostatic hyperplasia;
prostatitis or infection;
urinary retention;
recent instrumentation.

Initial evaluation

Before interpreting the result, we need to know:

age;
family history;
previous PSA values;
prostate volume when available;
symptoms;
digital rectal exam;
clinical situations capable of transiently changing the PSA.

When to refer?

persistently elevated PSA;
significant increase compared with previous measurements;
suspicious digital rectal exam;
relevant family history;
patient at increased risk of prostate cancer.

The urologist will decide on the need for:

repeating or supplementing the PSA;
multiparametric MRI;
biomarkers in selected situations;
prostate biopsy.

Key concept

Elevated PSA ≠ automatic biopsy. It is a signal that must be interpreted within the patient's individual risk.

Practical algorithm

🔴 Urgent referral / emergency

Sudden testicular pain → rule out torsion.
Fever/sepsis + obstructed urinary tract → urgent urinary drainage.
Acute urinary retention → bladder decompression; urgent referral if it cannot be resolved or if complications are present.
Hematuria + clot retention → urgent assessment and management.
Trauma + suspected urethral injury → avoid repeated blind catheterization attempts.

🟠 Priority referral

Solid testicular mass → rule out tumor.
Suspicious renal mass → characterization and urologic evaluation.
Gross hematuria → investigate the cause.
Persistently elevated PSA/suspicious DRE → prostate cancer risk assessment.

🟢 Scheduled referral depending on context

Recurrent UTI → look for a predisposing cause.
Erectile dysfunction → refer if complex, refractory, or with associated pathology.
Urinary incontinence → refer if complex, if warning signs are present, or if initial management fails.

The primary care physician does not need to resolve all urologic pathology. They must know how to perform an initial evaluation, recognize warning signs and, above all, distinguish which patient can wait from the one in whom a delay may compromise an organ, renal function, or even life.
