Objective: To investigate the factors, especially preoperative urinalysis, predicting postoperative early infection after retrograde intrarenal surgery (RIRS) in 1-2 cm renal stones. Methods: Of the 642 patients who underwent RIRS between September 2013 and July 2019, 289 patients with a total stone size of 1-2 cm were included in the study. Patients were divided into two groups as with and without postoperative urinary tract infection. The demographic data and perioperative findings of all patients were retrospectively reviewed. Sterile urine cultures were obtained in all patients during the preoperative 30-day period and urine analysis values were included in the data. Results: Urinary system infection (UTI) was seen in 20 (6.9%) of 289 patients. Patient demographics were similar between groups. There was no statistically significant difference between the two groups in terms of stone diameter and stone localization (median diameter 13.5 vs 15, p=0.285). Patients with postoperative UTI had a higher rate of UTI history (55% vs 20.5%, p=0.000) and longer operative times (62.5 vs 60 min., p=0.008). Rate of pyuria, leukocyte esterase and nitrite positivity were observed more frequently in patients with postoperative UTI. In multivariate analysis, UTI history, prolonged operative time, and nitrite positivity were found to be independent risk factors for postoperative UTI. Conclusion: Nitrite positivity in preoperative urinanalysis, history of UTI and prolonged operation time are the factors that predict the postoperative infection in RIRS for stones between 1-2 cm.
Objective: COVID-19 has rapidly spread and has become a pandemic by affecting the whole world. During this period, many scientific congresses and educational meetings had to be canceled because of preventive measures. In this report, we aimed to share our first live virtual congress experience, described its process of transformation from face to face to virtual congress and report the attendees and speakers’ satisfaction. Material and Methods: Eurasian Uro-oncological Association (EUA) decided to organize the 10th Eurasian Uro-oncology congress in June 2020 at Göbeklitepe, Şanlıurfa in Turkey. However, due to the COVID-19 pandemic, the organizing committee decided to organize the first virtual scientific congress in Turkey. The planned duration of the congress was reduced from 4 days to 2 days and each speaker was planned to give the speech online during the presentation via ZOOM program (San Jose, CA). Results: A total of 704 persons registered to the congress. It was the highest number of participants among whole congresses that was organized by EUA. In this congress, there were 199 oral presentations, 25 interactive e-posters and 12 video presentations. During the congress, each participant attended the congress for an average of 387 minutes. It was identified that the majority of the participants were quite satisfied with the program offered. In general, participants were fairly satisfied with the quality of images and sound, chat functionality, questions & answers section and technical support. Conclusion: In this report, we shared the outcomes of our first virtual congress experience in Turkey through the 10th Eurasian Uro-oncology Congress. Today, virtual congresses have become the "new normal" and offer cheaper events with larger participation in the comfort of home. Keywords: Congress, COVID-19, online, virtual, urology
