Article Effects of Visual and Auditory Stimuli on Performance During Sustained Attention Task(Galenos Yayincilik, 2020-04-01) Sendulger, Yamac; Adali, Sevim; Kilic, Fatma; Akin, Guliz; Ergonul, Ipek; Inanc, Gonca; Taslica, Serhat; Öztürk, Güliz Akın; Hurman, Ipek Ergonul; Onız, Adıle; Ozgoren, MuratObjective: Although many studies are investigating the effects of stimuli on sustained attention performance, only a few studies compare auditory, visual and neutral conditions. Thus, this study aimed to investigate the effect of visual and auditory stimuli on performance during sustained attention task. Materials and Methods: Twenty-six volunteers participated in this study. Participants executed sustained attention task in three different sessions. In the auditory session, participants listened to a highly paced folk music during the Mackworth Clock test. In the ''visual session, happy emoticons were presented around the test screen. In the neutral session, the test was carried out without any extra stimulus. The order of sessions was randomised. The time interval between sessions was at least 48 hours, and each session took 5 minute. The reaction times of all responses and correct responses and correct response rates were evaluated. Repeated-measures analysis of variance and Friedman tests were used depending on the distribution characteristics of data. Results: The reaction times of all responses or correct responses alone did not differ significantly among sessions. The correct response rates were 91.18%, 89.74% and 89.24% for the auditory, neutral and visual sessions, respectively. However, no statistically significant difference was found when these sessions were compared. Conclusion: Music was expected to improve performance in a sustained attention test, which is not complex but difficult because of monotony, like Mackworth Clock test. Visual stimuli are expected to hamper performance, as they share the modality of the test Although data had this trend, no statistically significant difference was found. Further research with increased number of participants and more difficult Mackworth Clock test, by extending its duration and using different types of music and visuals, is warranted.Article Citation - WoS: 2Effects of Three-Dimensional Measurement of the Urinary Stone Size on the Surgical Outcomes of Retrograde Intrarenal Stone Surgery(Galenos Yayincilik, 2021-06-09) Ergani, Batuhan; Kozacıoğlu, Zafer; Ergan, BatuhanObjective: This study aimed to investigate peri-/postoperative effects of three-dimensional measurement of stone size in patients who underwent retrograde intrarenal surgery, where preoperative stone size calculations determine the operation decisions and prognosis. Another aim is to determine a limit value in cm(3) for retrograde intrarenal surgery and to predict stone-free status based on this limit value. Materials and Methods: Data of 184 patients were retrospectively analysed. Patients were divided into two groups according to whether the stone-free status was achieved. Postoperative stone-free status and related effective parameters were analysed statistically. Results: No significant difference was found between age, gender, Hounsfield unit, length of hospital stay, secondary retrograde intrarenal surgery, renal unit abnormality, stone side, stone opacity, presence of additional ureteral stone, hydronephrosis and preoperative Double-J stent placement with stone-free rate. Subsequent interventions for residual stones, number of stones, stone sizes in cm(2) and cm(3) and operation time were determined as parameters that significantly affected the stone-free rate. As a result of the receiver operating characteristic analysis, the threshold stone size was 1.54 cm(3). Conclusion: More accurate indications can be determined by calculating the volume of the stone. Retrograde intrarenal surgery success decreases in stones >1.54 cm(3) by volume calculation. A different method such as percutaneous nephrolithotomy should be considered with higher preference for stones above this value.
