Signs and Symptoms InvesAgaAonsUrological History- Pain. Pain from inflamma+on = constant. Pain from obstruc+on = fluctua+ng ExaminaAon: General physical examina+on: JACCOL (jaundice, anaem

Ohenumoturia: passage of flatus per urethram (passing wind from front) Baseline (basic blood tests): CBC, U&Es, LFTs (check metabolic func+o
Urethral discharge: venereal disease; urethral carcinoma crea+nine, etc
Other important symptoms: Specific:
Rigors, fevers and chills – ?caused by an underlying UTI - may be asymptoma+c. - Stone; calcium, uric acid, etc
Cloudy urine may be caused by UTI, alkaline pH with phosphate crystal precipita+on, or - Prostate (prostate cancer?): PSA (PSA for prostate cancer is most
rarely by chyluria (lympha+c leak) - Testes (tes+cular cancer?) tumour markers: AFP, HCG, LDH
