SURGERY • URO-ONCOLOGY

A 62-year-old male, chronic smoker, presents with painless visible blood in urine for the past few weeks. He denies significant pain or dysuria. There is no palpable abdominal mass.

What is the most common presenting symptom of carcinoma of the urinary bladder?

A Frequency

B Dysuria

C C Hematuria

D Abdominal lump

E Deep vein thrombosis

Hematuria. Painless hematuria in an elderly smoker is the classic "red flag" presentation for bladder malignancy until proven otherwise.

Decoding Clue

1

CLUE "Elderly + smoker + painless bleeding"

TRANS Standard board presentation for Bladder Carcinoma. Smoking is the #1 risk factor.

2

CLUE "Most common presenting symptom"

TRANS Blood in urine (Gross or Microscopic) occurs in ~85-90% of cases as the first sign.

Explanation

A. Frequency: Occurs later due to bladder irritation or reduced capacity. Not the most common initial sign.

B. Dysuria: Painful urination usually suggests infection, stones, or very advanced disease/carcinoma in situ (CIS).

D. Abdominal lump: Rare in bladder cancer; usually indicates advanced, locally invasive disease.

E. Deep vein thrombosis: A possible paraneoplastic phenomenon, but never a primary presenting complaint for bladder cancer diagnosis.
