IPSS QoL: the most important questionIf you were to spend the rest of
your life with your urinary
condition just the way it is now,
how would you feel about that?

The physical examination
1. Abdominal examination
→ rule out other possible urinaryor rectal conditions
2. Digital Rectal Examination(DRE)
→ fundamental method forassessing the shape and thevolume of the prostate

Serum Prostate-Specific Antigen (PSA)
• Measurement recommended for patients with at least 10-year life expectancy and for whom knowledge of the presence of prostate cancer would change management
• PSA is also a proxy of prostate size but its variability is high. Recent studies suggest that it may be used to predict the risk of AUR and BPH-related surgery.

PSA and its role in therapeutic decision making
• PSA and PV are powerful predictors of risk of BPH progression
• PSA values of >1.6ng/mL predict a PV >40mL, PSA values of >1.4ng/mL predict a greater risk of BPH progression
• PSA can be used to identify candidates for intervention with appropriate therapy in order to reduce an increased risk of BPH progression and improve their QoL EAU BPH guidelines

Routine assessment of male LUTS: EAU guideline recommendations
LE GR
A medical history must be taken from men with LUTS 4 A
A validated symptom score questionnaire with QoL
assessment should be used during the assessment of male LUTS
and for re-evaluation of LUTS during treatment
3 B
Physical examination including DRE should be a routine part of
the assessment of male LUTS
3 B
Urinalysis (dipstick/urinary sediment) must be used in the assessment of male LUTS
3 A
PSA measurement should be performed only if a diagnosis of
PCa will change the management or if PSA can assist in decision-
making in patients at risk of progression of BPE
1b A
Measurement of PVR in male LUTS should be a routine part of
the assessment
