The effect of urinary system ultrasound on patient satisfaction in urology outpatient practice

In some state hospitals available imaging modalities are only X-ray and ultrasonography (USG) for urology practice. Our aim was to determine the satisfactory effects of urinary system USG in urology outpatients.We prepared a questionnaire to evaluate the satisfaction levels of the patients that admitted to our clinic with flank pain. Patients filled the questionnaire after their physical examination and treatment completed. 160 patients admitted to our clinic between January 2008 and May 2008 were enrolled in this study. We apply urine analysis and urinary system X- ray to 80 of them (Group I). Additionally urinary system USG performed to the other 80 patients (Group II) besides other laboratory workup. Two groups had similar sociodemographic characteristics (p>0.05). Responses to questions about the attitudes of the doctors and the nurses were not different between two groups (p>0.05). But patients’ confidence about the diagnosis and the treatment were found to be different between two groups (p<0.05).In conclusion, patients’ satisfaction is an important parameter for evaluation of the quality of health services. According to our results, USG increases the patient’s satisfaction in urology practice. Physicians should consider patients’ demands together with their clinical experience if they appropriate for medical ethics

Diagnostic accuracy and effective radiation dose of high pitch dual source multidetector computed tomography in evaluation of coronary artery bypass graft patency

Objective: The aim of the study was to evaluate the diagnostic accuracy and effective radiation dose (ERD) of high pitch dual source multidetector computed tomography (MDCT) for coronary artery bypass graft (CABG) patency. Materials and methods: Fourty-five patients who underwent 128 × 2-slice MDCT angiography with a prospective electrocardiogram-triggering, low-dose, high pitch, dual source, flash spiral acquisition mode after CABG surgery were included in the study. The interobserver agreement of the image quality was evaluated with Cohen ? value. The image quality was compared to the heart rates (HRs) using Mann–Whitney U test and to the graft segments using ? 2 test. The findings for the CABG patency on MDCT were compared to those determined on catheter coronary angiography. Dose-length product (DLP) and ERD were compared to the gender, HRs, and body mass index (BMI) of the patients using Kruskall Wallis and Mann–Whitney U tests. Results: A total of 110 grafts and 330 vessel segments were evaluated with a good interobserver agreement (? = 0.80). The image quality was better in proximal and middle graft segments (p &lt; 0.05), as well as in the patients with low HRs (p &lt; 0.05). High pitch MDCT had the following sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy for evaluation of graft patency: 92.8, 99.3, 92.8, 99.3 and 98.8 %, respectively. ERD was correlated to the HRs and BMI. Conclusions: High pitch 128 × 2-slice dual source CT angiography is a noninvasive imaging modality, and it can be safely and effectively used in evaluation of CABG patency with lower radiation dose. © 2016, Springer-Verlag Wien

Magnetic resonance enterography with oral mannitol solution: Diagnostic efficacy and image quality in Crohn disease

Purpose The aim of this study was to investigate the diagnostic efficacy and image quality of magnetic resonance enterography (MRE) using oral mannitol solution for the evaluation Crohn disease (CD). Materials and methods We retrospectively evaluated MRE examinations of 153 patients with an assumed or definitive diagnosis of CD. There were 65 men and 88 women, with a mean age of 35.7 years (range: 6–73 years). MRE findings of the patients were compared to histopathologic results obtained by surgery-fiberoptic endoscopy. The sensitivity, specificity and diagnostic efficacy rate were calculated. Additionally, image quality of MRE was evaluated using a four-point scale (1 = excellent, 4 = poor/non-diagnostic). Results Sensitivity, specificity and diagnostic efficacy were 92.5%, 93% and 92.8%, respectively. Six patients had false-positive and five patients had false-negative findings. Three falsely positive patients had ulcerative colitis and three had non-specific terminal ileitis. A total of 765 small bowel segments were analyzed; 475 (62%) had an image quality score of 1 and 15 (2%), an image quality score of 4. Conclusion MRE using oral mannitol solution provides excellent image quality for MRE and has high degrees of diagnostic efficacy in CD patients. © 2017 Editions françaises de radiologi
