Examination

• Examination of the abdomen for signs of a distended bladder, such as abdominal distention and suprapubic dullness on percussion.

• A check of the external genitalia to identify conditions which may cause or contribute to LUTS, for example phimosis, meatal stenosis, or penile cancer.

• A digital rectal examination to assess the prostate for size, consistency, nodules, and tenderness.

• Examination of the perineum and/or lower limbs to evaluate motor and sensory function.

Investigations

• A dipstick test of the urine to check for blood, glucose, protein, leucocytes, and nitrites.

• Serum creatinine and estimated glomerular filtration rate (eGFR) should be measured if clinically indicated.

• Prostate specific antigen (PSA) testing should be done only after discussing the indications for the test and the interpretation and implications of the results, and considering with the man whether an abnormal result would affect further management choices. The man should be given sufficient time to decide if he wishes to have the test.

Men with bothersome LUTS should be advised to complete a urinary frequency-volume chart to distinguish between
urinary frequency, polyuria, nocturia, and nocturnal polyuria.

Men considering any treatment for LUTS should be offered an
assessment of their baseline symptoms
validated symptom score, such as the International Prostate Symptom Score (IPSS),
to allow assessment of subsequent symptom change
