ABSTRACT
Background/Aim: To evaluate the performance of Chat Generative Pre-trained Transformer (ChatGPT), a large language model trained by Open artificial intelligence. Materials and Methods: This study has three main steps to evaluate the effectiveness of ChatGPT in the urologic field. The first step involved 35 questions from our institution's experts, who have at least 10 years of experience in their fields. The responses of ChatGPT versions were qualitatively compared with the responses of urology residents to the same questions. The second step assesses the reliability of ChatGPT versions in answering current debate topics. The third step was to assess the reliability of ChatGPT versions in providing medical recommendations and directives to patients' commonly asked questions during the outpatient and inpatient clinic. Results: In the first step, version 4 provided correct answers to 25 questions out of 35 while version 3.5 provided only 19 (71.4% vs 54%). It was observed that residents in their last year of education in our clinic also provided a mean of 25 correct answers, and 4th year residents provided a mean of 19.3 correct responses. The second step involved evaluating the response of both versions to debate situations in urology, and it was found that both versions provided variable and inappropriate results. In the last step, both versions had a similar success rate in providing recommendations and guidance to patients based on expert ratings. Conclusion: The difference between the two versions of the 35 questions in the first step of the study was thought to be due to the improvement of ChatGPT's literature and data synthesis abilities. It may be a logical approach to use ChatGPT versions to inform the nonhealth care providers' questions with quick and safe answers but should not be used to as a diagnostic tool or make a choice among different treatment modalities.
ABSTRACT
Background and Aim: Erectile dysfunction (ED) is an important and commonly seen disorder in patients with non-alcoholic fatty liver disease (NAFLD). The objective of this study was to assess the rate of ED and its causes in a group of NAFLD patients. Materials and Methods: The International Index of Erectile Function questionnaire (IIEF-5) was used to evaluate the presence, causes, and severity of ED. Participants with an IIEF-5 score of <22 who agreed to undergo a urological evaluation were referred to a urologist for further assessment. Results: A total of 136 NAFLD patients were enrolled in the study. According to the IIEF-5, 68 (50.0%) patients had ED. Multivariate analysis indicated that older age, obesity, and hypertension were associated with ED. Seventeen patients had multiple etiological factors for ED. Psychogenic ED was identified in 19 patients (39.6%), vasculogenic ED in 35 patients (72.9%), drug-related ED in 3 patients (6.3%), and neurogenic ED in 6 patients (12.5%). Conclusion: ED is frequently seen in NAFLD patients, which may, at least in part, be due to common risk factors. Vasculogenic dysfunction is the most common single source of ED in NAFLD patients. Nonetheless, all potential etiologies should be carefully investigated, with special attention given to psychogenic factors, since they may be more frequent and relevant than expected.
ABSTRACT
Flexible Ureterorenoscopy (F-URS) has dramatically changed the era of Renal stone management. One of its rare complications is retained objects. Some reports, described accidental breakage is reusable ureteroscope. Here we present 36-year-old male patient who underwent to F-URS in another institute March 2018. Four months later presented to our hospital with right flank pain. Renal Us showed mild hydronephrosis associated with 13 mm renal stones. Patient underwent F-URS, when we found the broken tip of disposable ureteroscope retained from the first operation. Urologist should always pay careful attention to the flexible ureteroscpe to check for any sign of breakage before and after the procedure.
ABSTRACT
INTRODUCTION: To understand the current practice of flexible ureteroscopy (fURS), we conducted a worldwide survey among urologists with a special interest in endourology. MATERIAL AND METHODS: A 42-question survey was designed after an initial consultation with European Association of Urology young academic urologists (YAU) and uro-technology (ESUT) groups. This was distributed via the SurveyMonkey® platform and an ESUT meeting to cover practice patterns and techniques in regard to ureteroscopy usage worldwide. RESULTS: A total of 114 completed responses were obtained. A safety guidewire was reportedly used by 84.5% of endourologists, an access sheath was always or almost always used by 71% and a reusable laser fibre was used by two-thirds of respondents. While a combination of dusting and fragmentation was used by 47% as a preferred mode of intra-renal stone treatment, some used dusting (43%) or fragmentation with basketing (10%).Disposable scopes were only used by 40% and three quarters of them used it for challenging cases only. Antibiotic prophylaxis was limited to a single peri-operative dose by two-thirds (67%) of respondents. The procedural time was limited to between 1-2 hours by two-thirds (70%) of respondents and very rarely (7.4%) it exceeded 2 hours. The irrigation method varied between manual pump (46%), mechanical irrigation (22%) or gravity irrigation (27%). CONCLUSIONS: Our survey shows a wide variation in the available endourological armamentarium and surgical practice amongst urologists. However, there seems to be a broad agreement in the use of peri-operative antibiotics, access sheath usage, method of stone treatment and the use of post-operative stent.
