Comparative Analysis of the Accuracy and Readability of the Answers Given by ChatGPT, Deepseek and Gemini Artificial Intelligences about Penile Body Dysmorphic Disorder
(Yuzuncu Yil University Tip Fakultesi, 2026) Demir, M.; Kotan, M.; Sarıhan, M.H.; Ertas, K.; Aslan, R.; Eryilmaz, R.; Taken, K.
This study contrasts the validity and legibility of responses of three computer algorithms—ChatGPT, DeepSeek, and Gemini to Penile Body Dysmorphic Disorder (BDD), where individuals are concerned with penis size. As individuals more and more rely on AI to seek health knowledge, this research contrasts the validity and readability of AI-generated responses to common penile size and function questions. Fourteen frequently asked questions about penis size and function were collected from social media and posed to ChatGPT, DeepSeek, and Gemini. Responses were evaluated with the Discern index to evaluate reliability and the Gunning Fog index to measure readability. For statistical analysis one-way ANOVA and one-way ANOVA and Post hoc tests were used. There was no significant difference between three algorithms (p=0.063), and the distinct scores for ChatGPT, DeepSeek, and Gemini were 3.29±1.07, 3.86±0.66, and 3.43±0.85. In comparison to DeepSeek (19.81±1.88) and Gemini (20.07±2.37), ChatGPT produced a significantly lower Gunning Fog score of 18.34±1.72 (p=0.012), suggesting that ChatGPT responses were easier to read. The study found all three AI models provided accurate and informative content about Penile BDD, where DeepSeek provided the most precise and ChatGPT the easiest to read. However, AI should never replace expert m edical recommendations. Continuous improvement and ethical reasoning are required to ensure safe application of AI for health information. © 2026, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
An Effective Treatment Option for Pain Caused by Urolithiasis: a Randomised-Controlled Trial of Local Active Warming With Heat-Patch
(Blackwell Publishing Ltd, 2021) Mutlu, H.; Ertas, K.; Kokulu, K.; Sert, E.T.; Diri, M.A.; Gul, M.
Background: There is growing interest in physical medicine treatment options for renal colic. In this study, we aimed to determine whether or not heat-patch treatment with no drug was effective in relieving renal colic. Methods: For this purpose, patients who were diagnosed with renal colic in the emergency department were randomised to have either heat-patch or sham treatment. The Visual Analogue Scale (VAS) scores of renal colic, body temperature (Btemp), and sub-patch skin temperature (Stemp) values were measured at 0, 15, 30, 45, and 60 minutes. In addition, the salvage treatment needs of the groups were compared. Results: The average age of the study group was 30.5 ± 8.3 years and that of the sham group was 31.0 ± 8.2 years (P =.75). According to the baseline VAS score of the patients, 15, 30, 45, and 60 minutes VAS scores significantly decreased in the heat-patch group (P <.001). The Btemp values did not differ significantly between the heat-patch and sham groups. In addition, no statistically significant difference was found between the two groups in terms of Stemp values at 0 and 15 minutes (P =.39 and P =.10, respectively). However, there was a significant difference in the heat-patch group in terms of Stemp values at 30, 45, and 60 minutes compared with the sham group (P <.001). The salvage treatment rates for the heat-patch and sham groups were 11.5% and 31.4%, respectively (P =.01). Conclusion: As non-pharmaceutical treatment, the heat-patch has been shown to be a possible candidate for pain relief in patients with urolithiasis. Further research should concentrate on multicentre and large scale randomised studies. © 2020 John Wiley & Sons Ltd
How Does Puncture Modality Affect the Risk of Intraoperative Bleeding During Percutaneous Nephrolithotomy? A Prospective Randomized Trial
(Elsevier Espana, 2021) Sahan, A.; Cubuk, A.; Ozkaptan, O.; Ertas, K.; Toprak, T.; Eryildirim, B.; Sarica, K.
Introduction and objectives: To evaluate the possible effects of two different renal puncture techniques (ultrasound-assisted [US-assisted], fluoroscopic-guided [FG]) on the intraoperative hemorrhage risk during percutaneous nephrolithotomy (PCNL). Material and methods: A total of 130 patients with Guy stone scores of 1-2 were prospectively allocated to US-assisted and FG puncture groups by simple randomization. Patients with intraoperative pelvicalyceal rupture and the ones requiring multiple accesses were excluded from the study. Apart from the puncture steps, all other steps of the PCNL procedure were performed with similar techniques by a single surgeon. Patient characteristics, operative data, and postoperative outcomes were compared. Results: A total of 10 patients were excluded from the study due to intraoperative complications after puncture. Patient demographics and stone characteristics were similar between the two groups (p > 0.05). Mean hemoglobin drop was meaningfully greater in the FG group (1.7 g/dL) when compared with US-assisted group (1.3 g/dL) (p < 0.01). The mean duration of radiation exposure was significantly higher for the FG (p < 0.001). Total operative time, number of attempts for a successful puncture, length of hospital stay, and stone free rates were similar between the groups (p > 0.05). In addition, the remaining complications classified according to the modified Clavien-Dindo grading system were similar between groups (p > 0.05). Conclusion: US-assisted puncture provides significantly decreased level of hemoglobin drop and radiation exposure time when compared with FG. (c) 2021 AEU. Published by Elsevier Espana, S.L.U.
