“…However, it administers a high dose of radiation to patients and follow-up is expensive, thus limiting its application. Previous studies determined that the conventional and low effective doses of UMDCT are higher than those of DTS (4,(8)(9)(10). In the present study it was determined that the detection rate of DTS prior to bowel preparation was 94.2%.…”

“…However, the radiation dose and cost of UMDCT is high and UMDCT is unable to evaluate renal function. The development of digital tomosynthesis (DTS) has received a lot of attention as it administers a low dose of radiation and has a high resolution (7)(8)(9)(10). DTS technology is widely used within dentistry and orthopedics as well as in the imaging of the breast, chest and blood vessels (11,12).…”

Abstract. Urinary calculus is a common and recurrent condition that affects kidney function. The present study evaluated the use of digital tomosynthesis (DTS) and Kidneys-Ureters-Bladder (KUB) radiography as methods of diagnosing urinary calculi. Unenhanced multidetector computed tomography (UMDCT) was used in the diagnosis of calculi. KUB radiography and DTS procedures were conducted on patients prior to and following bowel preparation to detect kidney, ureteral and bladder calculi. Differences in diagnostic performance of KUB radiography and DTS imaging on prepared and unprepared bowel were evaluated using the χ 2 test. The consistency of diagnostic results between two examining physicians was analyzed using the κ test. A total of 138 calculi from 80 patients were detected via UMDCT. The calculi detection rates of KUB prior to and following bowel preparation were 47.8 and 66.7% respectively, and the calculi detection rate of DTS prior to and following bowel preparation were 94.2 and 96.4%, respectively. The detection rates of calculi >5 mm via KUB prior to and following bowel preparation were 56.6 and 73.5% respectively, and in DTS they were 100% prior to and following bowel preparation. Economically, DTS performed on the unprepared bowel was the most cost effective, followed by DTS on the prepared bowel, KUB on the unprepared bowel and KUB on the prepared bowel. Therefore, the current study concluded that DTS may be an appropriate first-line imaging technique in patients with urinary calculi.

“…The characteristics of non-ionic iodine contrast material are having a high concentration of iodine, soluble in water, minimum viscosity, low osmotic pressure, do not undergo metabolic degradation, low affinity for proteins and is heat stable. Another advantage of non-ionic contrast material is the risk of nephrotoxicity is lower 14,15 .…”

Abstract:Purpose: The procedure of bowel preparation before intravenous urography (IVU) is still a controversial debate and it varies in each health center. Preparation is believed to reduce residual feces and intestinal gas thus improving the quality of visualization of the urinary tract. On the other hand, many radiology and urology studies did not mention the need for preparation before IVU procedure. Preparation before IVU, especially giving laxative agent, gives many adverse effects to the patient. The purpose of this study was to know the difference in quality visualization of the urinary tract in IVU patients with and without preparation in Saiful Anwar hospital Malang. Materials and Methods: A total of 20 patients participated in this study and they were divided into two groups in which each group consists of 10 patients with and without preparation before IVU. Abdominal x-ray and IVU were performed on all patients. Urinary tract visualization quality assessment was done through two methods of assessing the quality of the image by the European Commission Guidelines and of assessing the residue of feces/ intestinal gas based on Dadkhah's studies. Results: Results showed the total score of image quality and the residue of feces/intestinal gas was not significantly different in the abdominal plain photo of IVU patients with and without preparation (Mann-Whitney test (p=1.000) and Independent T-test (p=0.5111)). Conclusions: In conclusion, there was no difference in the quality of visualization of the urinary tract in IVU patients with and without preparation in Saiful Anwar hospital Malang.

Patients receive significant radiation exposure during the diagnosis, treatment, and follow-up of urinary stone disease. This radiation exposure may result in patient harm and is believed to contribute to the risk for malignancy. This review will present current information to allow surgeons to optimize their diagnostic, treatment, and follow-up regimens to allow optimal care of stone disease patients at the lowest radiation dose possible.
