Bedside ultrasound: a useful tool for the on-call urologist?
OBJECTIVE
To assess the accuracy and benefit of urgent bedside ultrasound scanning in urological emergencies by urology trainees.


METHODS
In this prospective study, 111 patients (86 acute flank pain, 15 renal failure, 10 haematuria) referred as urological emergencies, were scanned for urinary tract abnormalities at the bedside, by a trainee urologist, over 18 months. The ultrasound findings were compared with the results of imaging performed by a consultant radiologist and its influence on clinical management analysed.


RESULTS
Bedside ultrasound proved life saving in 5 patients (2 pyonephrosis, 2 leaking aneurysms, one bilateral ureteric injury). It significantly influenced management in 11 patients, excluded obstruction in the presence of infection.in 13 patients, helped in early diagnosis in 32 patients and ruled out gross urological pathology in 28 patients. It was misleading in 22 patients, mainly with ureteric colic (where the timing of the test can affect the findings), though the outcome was not adversely affected in any. Bedside ultrasound was reasonably accurate (sensitivity 81% and specificity 92%).


CONCLUSIONS
Bedside ultrasound is a useful tool to help the decision-making in urological emergencies and reasonably accurate in hands of a trainee urologist. It is especially helpful for excluding obstruction in presence of infection or renal failure. However it has inherent limitations in assessing acute ureteric colic.
