RESUMEN
OBJECTIVES: Artificial intelligence (AI) applications are increasingly being utilized by both patients and physicians for accessing medical information. This study focused on the urolithiasis section (pertaining to kidney and ureteral stones) of the European Association of Urology (EAU) guideline, a key reference for urologists. MATERIAL AND METHODS: We directed inquiries to four distinct AI chatbots to assess their responses in relation to guideline adherence. A total of 115 recommendations were transformed into questions, and responses were evaluated by two urologists with a minimum of 5 years of experience using a 5-point Likert scale (1 - False, 2 - Inadequate, 3 - Sufficient, 4 - Correct, and 5 - Very correct). RESULTS: The mean scores for Perplexity and ChatGPT 4.0 were 4.68 (SD: 0.80) and 4.80 (SD: 0.47), respectively, both significantly differed the scores of Bing and Bard (Bing vs. Perplexity, P<0.001; Bard vs. Perplexity, P<0.001; Bing vs. ChatGPT, P<0.001; Bard vs. ChatGPT, P<0.001). Bing had a mean score of 4.21 (SD: 0.96), while Bard scored 3.56 (SD: 1.14), with a significant difference (Bing vs. Bard, P<0.001). Bard exhibited the lowest score among all chatbots. Analysis of references revealed that Perplexity and Bing cited the guideline most frequently (47.3% and 30%, respectively). CONCLUSION: Our findings demonstrate that ChatGPT 4.0 and, notably, Perplexity align well with EAU guideline recommendations. These continuously evolving applications may play a crucial role in delivering information to physicians in the future, especially for urolithiasis.

PURPOSE: To predict the post transurethral prostate resection(TURP) urethral stricture probability by applying different machine learning algorithms using the data obtained from preoperative blood parameters. METHODS: A retrospective analysis of data from patients who underwent bipolar-TURP encompassing patient characteristics, preoperative routine blood test outcomes, and post-surgery uroflowmetry were used to develop and educate machine learning models. Various metrics, such as F1 score, model accuracy, negative predictive value, positive predictive value, sensitivity, specificity, Youden Index, ROC AUC value, and confidence interval for each model, were used to assess the predictive performance of machine learning models for urethral stricture development. RESULTS: A total of 109 patients' data (55 patients without urethral stricture and 54 patients with urethral stricture) were included in the study after implementing strict inclusion and exclusion criteria. The preoperative Platelet Distribution Width, Mean Platelet Volume, Plateletcrit, Activated Partial Thromboplastin Time, and Prothrombin Time values were statistically meaningful between the two cohorts. After applying the data to the machine learning systems, the accuracy prediction scores for the diverse algorithms were as follows: decision trees (0.82), logistic regression (0.82), random forests (0.91), support vector machines (0.86), K-nearest neighbors (0.82), and naïve Bayes (0.77). CONCLUSION: Our machine learning models' accuracy in predicting the post-TURP urethral stricture probability has demonstrated significant success. Exploring prospective studies that integrate supplementary variables has the potential to enhance the precision and accuracy of machine learning models, consequently progressing their ability to predict post-TURP urethral stricture risk.

INTRODUCTION AND HYPOTHESIS: The development of recurrent urinary tract infections (rUTIs) is not completely understood. This review is aimed at investigating the connection between genetics and rUTIs and summarizing the results of studies that have documented variations in gene expression among individuals with rUTIs compared with healthy individuals. METHODS: A systematic search was conducted in Cochrane, Ovid, and PubMed, limiting the results to articles published between 1 January 2000, and 5 July 2022. Only studies comparing the difference in gene expression between individuals with rUTI and healthy individuals utilizing molecular techniques to measure gene expression in blood or urine samples were included in this systematic review. Gene network and pathways analyses were performed using Cytoscape software, with input data obtained from our systematic review of differentially expressed genes in rUTIs. RESULTS: Six studies met our criteria for inclusion. The selected studies used molecular biology methods to quantify gene expression data from blood specimens. The analysis revealed that gene expressions of CXCR1 and TLR4 decreased, whereas CXCR2, TRIF, and SIGIRR increased in patients with rUTI compared with healthy controls. The analysis demonstrated that the most significant pathways were associated with TLR receptor signaling and tolerance, I-kappa B kinase/NF-kappa B signaling, and MyD88-independent TLR signaling. CONCLUSIONS: This systematic review uncovered gene expression variations in several candidate genes and identified a number of underlying biological pathways associated with rUTIs. These findings could shift the treatment and prevention strategies for rUTIs.

INTRODUCTION: To measure the level of endothelial cell-specific molecule-1 (ESM-1) expression among the Renal Cell Cancer (RCC) variants using by immunohistochemical method and determine the relationship between ESM-1 expression and RCC prognosis. MATERIALS AND METHODS: ESM-1 immunoreactivity scores (IR) were measured in appropriate renal tumoral tissue blocks of 153 consecutive RCC patients in this retrospective analysis of prospectively collected data. Mean ESM-1 IR scores were calculated in patients who were pathologically diagnosed with clear cell RCC (ccRCC), papillary RCC (pRCC), and chromophobe RCC (chRCC). Progression-free survival and overall survival were evaluated using the log-rank test according to ESM-1 IR scores. Survival rates were calculated using Kaplan-Meier survival analysis. RESULTS: In the ccRCC group, the mean ESM-1 IR scores of those with local invasion were significantly higher than those without local invasion (Pâ¯=â¯0.014). The mean ESM-1 IR score of patients with metastatic ccRCC was significantly higher than those with non-metastatic ccRCC (P < 0.001). Considering all patients regardless of RCC subtype pathologies, the mean ESM-1 IR score in clinical stage 1 tumor was 3.82 ± 1.98, 4.87 ± 1.74 in clinical stage 2, 5.88 ± 2 in clinical stage 3, and 6.60 ± 2.23 in clinical stage 4. The mean ESM-1 IR score of patients with metastatic ccRCC was significantly higher than those with non-metastatic ccRCC (P < 0.001). The mean follow-up period for all patients in this study was 71 months (range 1-120 months). It has been shown that the higher the ESM-1 IR score, the lower the 10-year overall survival and disease-free survival rates (Pâ¯=â¯0.026, Pâ¯=â¯0.005). CONCLUSION: Immunohistochemical expression of ESM-1 may be a promising prognostic biomarker in RCC. Currently, some prognostic scoring systems are available for patients with localized and metastasized RCC. Incorporating ESM-1 expression in RCC into these existing prognostic scoring systems could improve these models and enhance the quality of individual oncologic management in RCC patients.

INTRODUCTION AND HYPOTHESIS: The objective was to comprehensively analyze YouTube™ videos focusing on genital gender-affirmation surgery (GAS) from the perspective of urologists and gynecologists and to utilize results to create educational videos for transgender individuals with accurate and engaging content. METHODS: A YouTube search was performed using the keywords "Metoidioplasty," "Phalloplasty," "Gender affirmation surgery," "Transgender surgery," "Vaginoplasty," and "Male-to-female surgery." Video results that were duplicated, non-English, of low relevance, non-audio, and/or short duration (under 2 min) were excluded. The upload source was classified as university/nonprofit physician or organization, health information websites, medical advertisement/for-profit organizations, or individual patient experience. Viewer engagement metrics were obtained for each video. Each video was evaluated using the DISCERN, Global Quality Score (GQS), and Patient Education Materials Assessment Tool for audio-visual content (PEMAT A-V) tools. RESULTS: A total of 273 videos were evaluated. Viewer engagement metrics of videos from the patient experience group were higher than those of both universities/nonprofit physicians and medical advertisement/for-profit groups. DISCERN and GQS scores were significantly lower in videos uploaded by the patient experience group than in each of the other upload sources. More videos covered female-to-male (FtM) transition (168, 61.5%) than covered male-to-female (MtF; 71, 26.0%), and both (34, 12.5%). MtF transition videos had significantly higher total view counts than videos from the other groups (p<0.001). The like counts of videos were significantly higher in both MtF transition and FtM transition groups than for videos explaining both types of transition within the same video. The total DISCERN score was significantly lower in FtM transition videos than in the other content groups. Two educational videos were prepared, informed by the tools and results of this study, and hosted on YouTube. CONCLUSIONS: The findings suggest that genital GAS videos with less technical content have higher audience engagement. This information should be used to aid medical organizations when creating YouTube content to provide accurate information to larger audiences in the transgender community.

INTRODUCTION AND HYPOTHESIS: Seeking health information online has drastically increased. As primary bladder pain syndrome (PBPS) is a condition that has no definitive diagnosis and treatment protocol, patients may seek answers on YouTube. We aimed to evaluate the role of the videos related to PBPS hosted on YouTube. METHODS: We searched PBPS-related YouTube videos using the keywords "primary bladder pain syndrome," "painful bladder syndrome," and "interstitial cystitis." The videos not in English, not relevant, or that do not contain audio were excluded. The characteristics of the videos were collected. The videos were primarily classified as reliable and nonreliable based on the scientifically proven accurate information they contained. The overall quality of the videos was assessed by DISCERN and Global Quality Score (GQS). Intraclass correlation was used to calculate the level of agreement between the two investigators on DISCERN and GQS values. RESULTS: Of the 300 videos, 175 were excluded. A total of 62 (49.6%) videos were considered reliable and 63 (50.4%) nonreliable. Only video lengths differed statistically in favor of reliable videos (p < 0.001). DISCERN and GQS values were higher in the reliable videos group (p < 0.001 for each). The number of views, likes, dislikes, and comments were slightly lower in the videos uploaded from universities/nonprofit physicians or professional organizations than other groups. CONCLUSIONS: Although about half of the videos are reliable, most are long and are medical lectures, from which it is difficult for nonhealth professionals and patients to obtain information. On the other hand, most of the videos that patients can follow more easily consist of nonreliable video groups that lack accuracy, detail, and factual content. Therefore, the relevant associations with experts should prepare concise videos containing correct and up-to-date information.

BACKGROUND: The purpose of this research was to compare the functional parameters of frozen-thawed Iranian Azari buffalo spermatozoa with imported semen samples of Italian Mediterranean buffalo (IMB) after the thawing process and 4 hours of incubation. MATERIALS AND METHODS: In this experimental study, a total of twenty-four ejaculates from four Iranian Azari buffalo bulls were collected. Semen samples were diluted in AndroMed extender at a concentration of 50×106 spermatozoa/ ml. The diluted samples were filled in 0.5 ml straws and were frozen in a programmable freezer. For imported semen samples, twenty-four samples of four IMB were used, which were diluted in AndroMed extender and frozen by the same procedure. Frozen-thawed sperm motion patterns, mitochondrial activity, membrane integrity, DNA integrity, reactive oxygen species (ROS), and apoptosis status were evaluated immediately after thawing and 4 hours of incubation. RESULTS: Post-thawed sperm motility, progressive motility (PM), mitochondrial activity, membrane integrity were significantly higher in imported semen samples in compare with Iranian Azari buffalo. After 4 hours of incubation, sperm velocity patterns were superior in Iranian Azari semen samples. Moreover, the percentage of sperm cells with un-damaged DNA was higher in Iranian semen samples compared to imported samples at the time 0 of incubation. Following 4 hours of incubation, a significant increase in intracellular ROS level leads to reduced membrane integrity, mitochondrial activity, and DNA integrity in both buffalo breeds. At time 4, Iranian samples showed significantly lower apoptosis and higher dead spermatozoa compared to imported semen samples. CONCLUSION: Our study showed that the post-thawed quality of Iranian Azari buffalo semen was comparable with imported samples after 4 hours of incubation. Further investigations are recommended to assess the in vitro and in vivo fertility rate of both buffalo breeds.
RESUMEN
INTRODUCTION: Following the COVID-19 pandemic, the face-to-face meetings are delayed to a future date, which is still not clear. However, seminars, meetings and conferences are necessary for updating our knowledge and skills. Web-based seminars (webinars) are the solutions to this issue. This study aimed to show the participant behaviour when webinars present at the COVID-19 pandemic era. METHODS: From December 2017 to July 2020, 58 webinars were broadcasted via the Uropedia, electronic library of SUST. Data of all webinars were collected with the YouTube analytics and application of the Uropedia. Data of streaming webinars included participant behaviours such as content views, engagement time, total unique attendees, average engagement time and the number of audience to leads. Data were split into two groups; group-1 is webinars before COVID-19 (before March 2020) and group-2 is the webinars during COVID-19. RESULTS: Total broadcast time and total page view number were found to be 112.6 hours (6761 minutes) and 15 919, respectively. The median participant age was 40.1 y. Median content view and median engagement time were found to be 261.0 and 12.2 minutes, respectively. Comparison of two groups revealed a significant increment in the content views (group-1; 134.0 range = 86.0-87.0 and group-2; 414.0 range = 296.0-602.0, P < .001) and the number of the unique attendees (group 1; 18.0 range = 10.0-26.0 and group-2; 57.0 range = 27.0-100.0, P < .001) following COVID-19. However, the median engagement time of the audience did not seem to change with the COVID-19 pandemic (group-1; 11.5 range = 10.0-13.3 minutes and group-2; 13.2 range = 9.4-18.1 minutes, P = .12). CONCLUSION: The webinars are effective ways to share information and have many advantages, including low cost, reaching a high number of audiences. Audience number and page visits seemed to increase following the COVID-19 pandemic. However, this era did not seem to affect the critical attitude of the audience, which is engagement time.

Erectile dysfunction (ED) shares several risk factors with diabetes mellitus (DM), hypertension (HT) and coronary vascular disease (CVD), which were well-associated with seasonal fluctuation with the highest peak in winter. In this study, we aimed to determine whether ED demonstrates seasonal fluctuations with the above-mentioned systemic diseases. Database from a tertiary university hospital between 2010 and 2020 was deciphered to retrieve patients diagnosed with ED. Patients with primary bladder tumour and post-procedural ED constituted the negative control groups from the same study period. International index of erectile function questionnaire (IIEF-15) was used to segregate included patients into mild/moderate and severe ED groups. The probability of detecting DM, HT and CVD in patients with severe ED was significantly higher than that of with mild/moderate ED (p < 0.05). More ED symptoms emerged and were diagnosed in the winter seasons even though no statistical significance was observed between patients with mild/moderate and severe ED (p = 0.946, Cramer's V coefficient = 0.19). The seasonal variation of patients with bladder tumour and post-procedural ED groups showed no significant difference (p > 0.05, both). ED admissions are associated with higher peaks in the winter seasons. This may help in daily clinical practice to warrant better clinical and epidemiological interpretation of ED.

PURPOSE: To determine whether the use of different bipolar resources is associated with different results on tissue and perioperative parameters in patients undergoing bipolar transurethral bladder tumor resection (bTURBT). METHODS: In this single-center prospective study, patients diagnosed with bladder tumor randomized to undergo TURBT either with a Gyrus PlasmaKinetic system (n = 62) or Olympus TUR in saline (TURis) system (n = 51). Primary endpoint was to evaluate the alteration of patients' perioperative parameters, while secondary aim was to assess the thermal effect of these 2 different bipolar devices on the resected tissue samples by a grading system determined by tissue characteristics. RESULTS: One hundred thirteen patients were randomized in the study, and 43 were excluded from the analysis due to the exclusion criteria. There were no significant differences between the groups in terms of mean age, tumor site, number of tumors, operative time, alteration in hemoglobin or hematocrit, blood transfusion rate, catheterization time, and postoperative stay. On the other hand, the ratio of obturator jerk was significantly higher in the Olympus TURis group (p = 0.028). The histopathological analyses of both groups determined muscularis propria and cautery artifact presence without a statistically significant difference (χ2: 0.476, p = 0.788). CONCLUSION: Although the perioperative complications of bTURBT are low in nature, bladder perforation resulted from obturator jerk still poses a risk for extravesical tumor implantation. Urologists should be aware of this risk especially when they are using a TURis system.

AIMS: To evaluate the awareness of the use of fluoroscopy in endourological procedures, as well as the theoretical and practical applications of preventive measures. MATERIAL AND METHOD: Between May 2018 and April 2019, a 26-question survey prepared using Google Docs was sent to urologists via email. Personal information, radiation training and behaviours related to radiation and fluoroscopy usage, and the use of protective equipment were queried. RESULTS: A total of 226 participants fully completed and returned the email survey. Of the 226 participants, 78 (34.5%) were academics, 44 (19.4%) were residents while 104 (46.1%) were experts. More than 60% of the participants stated that they participated in the operation requiring less than five fluoroscopy use per week. The majority of operations requiring fluoroscopy consisted of endourological procedures. The lead apron was used by 93% of the participants, but the use of protective glasses and gloves was very low (3.5%). The majority of academicians, experts and residents did not use dosimeters (76.9%, 82.7% and 81.8%, respectively). More than 50% of the participants did not have literature information about the harmful effects of radiation with the use of fluoroscopy. The most common complaints on the day of fluoroscopy were fatigue and headache. CONCLUSION: The lack of information regarding the radiation protection measures and harmful effects of radiation is common among urologists in Turkey. Therefore, systematic training programs on fluoroscopy use and radiation exposure should be provided during urology residency.

OBJECTIVE: To investigate the clinical value of preoperative De Ritis ratio (aspartate aminotransferase/alanine aminotransferase) (DRR) in patients with transitional cell bladder cancer (TCBC) at initial diagnosis. The secondary objective was to investigate the status of systemic inflammatory parameters, such as neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR) and platelet-monocyte ratio (PMR). MATERIALS AND METHODS: The records of patients with primary TCBC who underwent transurethral resection were retrospectively evaluated. The relationship of DRR and systemic inflammatory parameters with clinicopathological findings, recurrence and progression status was evaluated separately. RESULTS: There was no significant difference in the DRR according to the clinicopathological findings, recurrence and progression. Significant differences were found between the NLR and the patient groups for tumour diameter, tumour stage, tumour grade and progression. In univariate analysis, the LMR was found to be associated with progression, and also the PLR and LMR were found to be associated with recurrence. Decrease in LMR and increase in LMR score demonstrated by multiple analysis was shown as independent predictors of progression and recurrence development. CONCLUSIONS: This paper shows a positive correlation between poor prognosis in TCBC and the systemic inflammatory markers, namely NLR, LMR, PLR and PMR, but not DRR.
