Objectives: Aimed this study to estimate the sensitivity of non-contrast axial tomography with ureteroscopy in order to reveal the size and number of the actual ureteral calculation. Imaging methods focused on screening for patients with abdominal X-ray (KUB), ultrasound (US), and non-contrast computerized tomography (CT). Sensitivity range has been reported at a concentration of 58-62% (KUB), 45% (US), and 95-100% (CT). However, these results were not correlated with the results obtained laparoscopic ally.
Methods: This study was conducted by stone-makers, who have differential and integral calculations, and who suffer from deficiencies in conservative management that require ureteroscopy (URS). At the time of ureteroscopy it was recorded in relation to the length of the ureter by pushing the guiding wire towards the top electrode of the stone and then the tip of the guiding wire was pulled towards the bottom electrode of the stone. The difference in length was then measured at the outer end of the ureter and some stones were fully recovered by the basket formed in the dormitory and measured externally. All CT scan were reviewed by a urologist who explained the endoscopic results. Who reported the location, number, size and shape of each calculus.
Result: Fifty patients with ureteral stone were studied in this study. The time average range from (CT scan to URS) was 19 days. It was a middle stone site location was 16.8% in the upper ureter,29.7% in the mid ureter and 53.5% in the lower ureter. The mean number of calculi identified per patient in the upper ureter for endoscopy was 64.7% for one stone,35.3% for 2 stones.in the mid ureter26.7%one stone,73.3% for 2 stones.for the lower ureter 55.6% for 1 stone,33.3% for 2 stones,11.1% for 3 stones. while the mean number in CT for upper ureter 64.7% for 1 stone,35.3% for 2 stones, for the mid ureter 80% one stone and 20% 2 stones, for the lower ureter it was 72.2% one stone,27.8% 2stones. The mean length in the total kidney calculation (sum of the longest stone diameters) for each ureter was 13 mm and 11 mm for fluoroscopy and CT, respectively (p = 0.06) for the upper ureter, while for the average ureter was 14 mm and 12 mm, respectively, either the proportions The lower milker is 12 mm and 11 mm, respectively.
Conclusions: A CT scan had results by checking the number of ureteral calculations in various anatomical forms, and it was possible to discover some stones that may be small and unable to distinguish between lying close to each other and that CT scans also reach to reduce the size of the length of the ureter of the ureter.
