The role of the plain X-ray in the assessment of prostatic symptoms

To assess the contribution of a plain X-ray of the kidney, ureters and bladder (KUB) to the assessment of patients presenting with symptoms of bladder outlet obstruction.

All patients presenting to the 'Prostate' clinic at Weston General Hospital during the 12 months from 1 May 1993 to 30 April 1994 were assessed clinically by a history, examination and routine investigations that included a KUB examined and reported by a radiologist. Patients were followed and treatment instituted as deemed appropriate. The contribution made to the management of the patient by the KUB was assessed.

Of the 292 patients, 234 had no relevant abnormality detected: four patients had evidence of a bladder calculus, whilst in four osteosclerotic areas were noted on the pelvis and lumbar spine. Of the remainder, 14 (5%) had upper urinary tract calcification. In no patients did the KUB influence their immediate management. Those with asymptomatic upper tract stones were offered a yearly follow-up.

The routine use of the KUB as a means of investigating lower urinary tract symptoms in the male may no longer be necessary.
