Haematuria presenting in outpatients attending a department of genitourinary medicine.

Of all the patients attending a department of genitourinary medicine during a 10-month period, about 2% (1 out of 50) presented with haematuria, or haematuria was discovered on initial examination. In about 25% of cases, the haematuria was due to Escherichia coli infection of the lower genitourinary tract. Gonococcal infection was the next commonest cause; one patient with gonorrhoea presented with frank urethral bleeding. In the remaining patients other causes of haematuria, which included renal cyst. carcinoma of the ureter, bilharziasis, and IgA disease, required more extensive investigations and follow up.
