Abstract:
Renal stones are very common worldwide, with a lifetime risk of about 10%.
Prevalence of stone disease is much higher in the Middle East. Most stones
occur in the upper urinary tract .Imaging modalities playing important role
in investigate and diagnosing stone.
Ultrasound is none ionizing sound wave which is primary and fast method to
examine abdomen and pelvic organ, CT scan is ionizing radiation has high
quality to detect stone.
The main aim of this study was to evaluation of urinary tract stones using
ultrasound and unenhanced CT KUB.
The problem of this study was Ultrasound considered primary examination
for urinary system pathology however ultrasound show lack of information
and some practice obstacles, the research is conduct to evaluate ultrasound
finding compared to CT finding to show discrepancy of results as CT
considered golden method.
This study was retrospective analytical descriptive study of 109 cases in
Elribat university hospital from September 2015 till March 2016, all patients
were subjected to be examined by U/S scanning using ‘Siemens scanners
with 3,5MHz for adult and 5 MHz for children curvilinear probe, trans
abdominal Scanning were performed for all patients scanning renal system
for location and size of stone, and then done unenhanced CTKUB using
Siemens machine, took cross sectional for all area of renal system, then
measure the density of stone by using Hounsfield number, look for effect of
stone if there change in size of kidney or found hydro nephrosis or hydro
ureter .
V
Patients were had different age groups all of them had come to the
department complain of lion pain, with ultrasound and CT scan examination
the result found that the mean of the affected gender was found to be male
69.7%.
The ultrasound showed that most finding of stones were renal stone 77.1 %
however CT showed that renal stone were 65.1% the discrepancy ultrasound
is operator dependent in order 13.8 % was found to be normal.
Number of stones by CT was found to be solitary stone 66.1% and its most
site was found at lower pole of the kidney.
The study concluded that sensitivity to investigate stone using ultrasound is
less compering to CT scan.
The study recommended that uses multiple medical imaging modalities and
investigation to evaluate renal stone beyond ultrasound method in order to
increase the quality to detect stones.
