Background: Transrectal ultrasound biopsy is the preferred method for diagnosing prostate cancer, but it can cause infectious complications as a result of fluoroquinolone resistance. We aimed to explore the potential protective effect of a second rectal enema before biopsy. Methods: Between January 2015 and December 2020, 419 patients were assessed retrospectively. Patients with a history of anticoagulant use, uncontrolled diabetes, urological surgery, prostate biopsy, or recent hospitalization or overseas travel, as well as those with previous prostatitis, were excluded from the study. The patients were subsequently divided into two groups: Group 1 (n=223) had received one enema, on the morning of the biopsy, and Group 2 (n=196) had received two, with the additional enema administered half an hour before the procedure. Results: There was no significant difference between the groups in terms of age, BMI, diabetes, prostate-specific antigen (PSA) level, and prostate size (p=0.076, p=0.489, p=0.265, p=0.193, and p=0.661, respectively) or in relation to cancer detection (p=0.428). The median hospitalization date was significantly higher in Group 1 (p=0.003) as was UTI development (p=0.004). However, there was no significant difference in terms of fever and sepsis (p=0.524 and p=0.548, respectively). Additionally, subgroup analysis demonstrated that UTI was significantly lower in patients with diabetes mellitus who had received a second enema (p=0.004), though there was no significant difference in UTI between the groups in those without diabetes mellitus (p=0.215). Multivariable analysis showed that age and diabetes were significant risk factors for the development of UTI (p=0.002andp=0.003, respectively). Furthermore, the second enema was a significant protective factor for preventing UTI (p<0.001). Conclusion: Older age and the presence of diabetes mellitus are independent risk factors for UTI after prostate biopsy. A second enema procedure before biopsy may protect patients from related infectious complications and could therefore be used as an alternative preventative method.

Background: Preoperative bladder urine culture (PBUC) analysis has become a standard application before any stone surgery. When growth is detected in PBUC, it is contraindicated to perform flexible ureterorenoscopy (f-URS). The results of the PBUC susceptibility test do not correlate well with those of the renal pelvic urine culture (RPUC) analysis. Previous studies have demonstrated the positivity of RPUC as an important marker for the development of infections after endoscopic operations. In the current study, we aimed to evaluate the consistency between PBUC and RPUC and to identify preoperative markers associated with a positive RPUC. Methods: Data from 129 patients who underwent f-URS on renal and proximal ureteral stones in two centers between 2015 and 2020 were prospectively recorded in a database and retrospectively analyzed. PBUC was obtained from all the patients preoperatively, and RPUC was taken at the beginning of the f-URS operation. The results of the two cultures were compared. Results: There was growth in PBUC in 25 (19.4%) patients and RPUC in 35 (27.1%) patients. Possible predictive markers in predicting a positive RPUC were evaluated using multivariate logistic regression analysis. Preoperative urine density at the renal pelvis [odds ratio (OR): 0.848, p<0.001],grade≥2 hydronephrosis (OR:18.970,p=0.001), and lower calyceal stone localization (OR:0.033,p=0.017) were determined as independent predictive factors for a positive RPUC. The ability of pelvis urine density to predict positive RPUC positivity was evaluated using the receiver operating characteristic analysis, in which the area under the curve value was determined to be 0.858 (0.780-0.936). The cut-off value of pelvis urine density in the prediction of RPUC positivity was 4.5, at which it had 80% sensitivity and 77.7% specificity. Conclusions: PBUC may not represent true colonization. Although bladder urine culture is negative before the operation, patients with preoperative hydronephrosis and low pelvis urine density may have RPUC growth.

Objective: In this study, we aim to evaluate the content and quality of the most relevant YouTube videos related to Holmium laser enucleation of the prostate (HoLEP) surgery. Materials and Methods: The keywords ‘HOLEP’, ‘laser enucleation’ and ‘prostate enucleation’ were used to perform a search on YouTube. Non-English language videos, videos with less than 4-minute duration, and repetitive videos were excluded. The reactions of the viewers to the videos were evaluated by recording the ‘total views’, ‘views/month’ and ‘likes and dislikes’ parameters. The data were divided into two groups based on the source of upload: Group 1 consisted of healthcare providers and Groups 2 comprised commercial companies and for-profit organizations. Results: A total of 117 videos were included in the study. A significant portion of the videos (77.7%) had been uploaded by healthcare providers. There was no statistically significant difference between the uploading groups in terms of the DISCERN and GQS scores (p=0.484 and p=0.108, respectively). However, the PEMAT understandability and actionability scores were statistically significantly higher in Group 2 (p=0.004 and p=0.022, respectively). In addition, when the misinformation scale was evaluated, there were significantly more videos with high-degree misinformation in Group 2 (5.5% vs 33.3, p=0.001). Conclusion: On video sharing platforms, such as YouTube, the number of reliable videos with accurate and appropriate guidance about diseases and treatments should be increased, and these videos should be allowed to be posted after they have been approved by relevant institutions, including healthcare associations and universities.

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. The web-based seminars (webinars) are the solutions to this issue. This study aimed to show the participant behavior when webinars present at the Covid-19 pandemic era. Methods: Between December 2017 – 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 behaviors 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), 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 min.) and 15919, respectively. The median participant age was 40.1 years. Median content view and median engagement time were found to be 261.0 min., and 12.2 min., 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<0.001) 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<0.001) 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 min. and group 2; 13.2 range=9.4-18.1 min., p=0.12). Conclusion: The webinars are effective ways to share information and have many advantages, including low cost, reaching the high number of audiences. Audience number and page visits seemed to increase following the Covid-19 pandemic. However, The engagement time did not seem to affect a critical attitude of the audience

Abstract Purpose: To compare the functional outcomes of patients who underwent partial (PN) or radical nephrectomy (RN) for clinical T1 (cT1) renal tumors using the Kidney Cancer Database of the Urooncology Association, Turkey. Methods: We retrospectively reviewed 1004 patients who underwent PN and RN for cT1 renal tumors at multiple academic tertiary centers between 2000 and 2018. Patients with preoperative end-stage chronic kidney disease and/or metastatic disease were excluded. Results: There were 452 patients in the PN group and 552 patients in the RN group. The eGFR was significantly reduced in both groups on postoperative day one (PN=13.7 vs. RN=19.1 ml/min/1.73 m2: p<0.001). In the PN group, eGFR showed a tendency to recover according to a quadratic pattern and reached preoperative levels in the first and third years (95.6±28.8 ml/min/1.73 m2 and 96.9±28.9 ml/min/1.73 m2, respectively), with no significant difference between the eGFRs in the 1st and 3rd years (p=0.710). To define groups at risk, different cut-off values for the GFR were considered. Among patients with a baseline GFR<90, the RN cohort had significantly lower eGFRs in the first and third years than the PN cohort (p=0.02). Logistic regression showed that comorbidities, coronary artery disease, diabetes and hypertension had no adverse impacts on the changes in the eGFR (p=0.60, p=0.13, and p=0.13, respectively). Conclusion: For the treatment of stage T1 kidney tumors, the first choice should be open or laparoscopic partial nephrectomy due to the superior long-term preservation of renal function and overall survival, regardless of age and comorbidities.
