Abstract

Background and Objective: Bladder rupture is still occasionally seen in trauma patients, especially in those with
multiple organ injuries. If suspected, a standard diagnostic method is to perform retrograde cystogram. However,
this requires that a radiologist be available, and is not applicable in patients with unstable vital signs. A diagnostic
procedure that is more readily available is the saline instillation test under ultrasonographic visualization. The aim
of the present study was to determine the accuracy of saline instillation test under ultrasonography in diagnosing
traumatic bladder rupture.
Methods: A diagnostic study of saline instillation test under ultrasonography was undertaken, using retrograde
cystogram, CT scan, and operative findings as standard comparators.
Results: During January 2012 and December 2014, 19 patients were recruited into the present study,
consisting of 13 patients with bladder ruptures, one patient without bladder rupture, and six patients with injuries
to kidney. We found the saline instillation test under ultrasonography to be accurate, with a sensitivity of 92.3%,
specificity of 100%, positive predictive value of 100%, and negative predictive value of 85.7%.
Conclusion: The saline instillation test under ultrasonography for the diagnosis of traumatic bladder rupture
has good sensitivity and specificity. It was easy to perform, convenient and fast, and can provide a timely diagnosis,
leading to prompt treatment and probably a reduction in complications.
