Background/aim: The aim of this paper was to determine the general tendencies of urology patients and effect of COVID-19 pandemic on daily urological practice at tertiary centers located in the most affected area in Turkey. Materials and methods: We retrospectively analyzed the data of 39,677 patients (group 1) that applied to 6 different large-volume tertiary centers in İstanbul for outpatient consultation, surgery, or other procedures in the 3-month period between March 16 and June 14, 2020. The distribution of the number of patients who applied to subspecialty sections of urology outpatient clinics and inpatient services were recorded by weeks. That data was compared to data obtained from 145,247 patients that applied to the same centers in the same period of the previous year (group 2). The reflection of worldwide and Turkish COVID-19 case distribution on the daily urological practice was analyzed. Results: There was a decrease in the number of patients in all subspecialty sections the in group 1 compared to group 2; however, there was a significant proportional increase in urooncology and general urology admissions. A decrease of approximately 75% was observed in the total number of surgeries (p < 0.001). We detected a negative correlation between the numbers of admission to all outpatient clinics and COVID-19 cases or deaths in Turkey (p < 0.05). The same negative correlation was present for all surgical procedures and consultations (p < 0.05). The multivariate linear regression analysis revealed that the number of cases in Turkey, and the number of deaths worldwide affect the number of outpatient clinic admissions (R2 = 0.38, p = 0.028) and urological surgery (R2 = 0.33, p = 0.020) in Turkey negatively. Conclusion: This novel pandemic has implications even for urology practice. Urological surgical procedures were more affected by COVID-19-related deaths in Turkey and worldwide. Outpatient admissions and urological surgeries decreased significantly by increasing COVID-19 case numbers in Turkey and worldwide deaths. [ABSTRACT FROM AUTHOR]

Background/aim: Although it has been shown that the neutrophil-to-lymphocyte ratio (NLR) may predict the progression of nonmuscle invasive bladder cancer (NMIBC), its association with the recurrence of NMIBC has been poorly studied. The aim of this study is to evaluate the association between NLR and disease recurrence in patients with NMIBC. Materials and methods: The medical records of 428 consecutive initially diagnosed NMIBC patients who underwent transurethral resection between January 2010 and July 2014 were retrospectively reviewed. Patients without a preoperative NLR (n = 6), without a minimum of 6 months of follow-up (n = 56), who were lost to follow-up (n = 38), or who had progressive disease during follow-up (n = 42) were excluded. The demographics, tumor characteristics, and NLRs of patients with and without tumor recurrence were compared. Results: Of 286 patients who met the inclusion criteria, 68 (17.43%) had recurrent disease. Tumor size (P = 0.198), tumor type (P = 0.929), and the presence of carcinoma in situ (P = 0.373) were also similar between groups. Patients with recurrent disease had a higher mean NLR (2.62 ± 0.99 vs. 2.2 ± 0.96, P = 0.002). Conclusion: Our results show that NLR may be used as a predictor of recurrence in patients with NMIBC; however, prospective studies are required to validate these findings. [ABSTRACT FROM AUTHOR]
