Purpose: To evaluate the effect of partial nephrectomy on renal function and to identify predictors of estimated glomerular filtration rate (eGFR) at six months after partial nephrectomy. Methods: Medical data of 154 consecutive patients who underwent partial nephrectomy for a renal mass between January 2015 and March 2020 were retrospectively analyzed. The primary outcome measure was eGFR at six months postoperatively. A non-linear regression analysis was performed to examine the association between primary outcome measure and candidate predictors. Results: Of the patients, 66 (42.9%) were females and 88 (57.1%) were males with a median age of 60 (range, 50 to 67) years. The median baseline eGFR was 90.40 (range, 74.96 to 102.97) mL/min/1.73 m2, while the median eGFR at six months was 77.12 (range, 61.06 to 91.93) mL/min/1.73 m2 (p<0.001). Baseline eGFR (=22.691, 95%CI: 18.821 to 26.460, when baseline eGFR levels change from 74.97 ml/min/1.73 m2 to 102.68 ml/min/1.73 m2, p<0.001) was found to be directly associated with the postoperative eGFR levels at six months. In contrary, advanced tumor size (=-3.168, 95%CI: -5.332 to -1.005, when tumor size levels change from 3 to 6 cm, p<0.001) and presence of hypertension ( = -3.479, 95%CI: -6.956 to -0.0031, p=0.049) were also found to be inversely associated with the postoperative eGFR levels at six months. Conclusion: Baseline eGFR values, tumor size, and presence of hypertension are significant predictors of eGFR values in the mid-term in patients undergoing partial nephrectomy.

Objective: To present a nation-wide analysis of the workload of urology departments in Turkey week-by-week during Covid-19 pandemic. Methodology: The centers participating in the study were divided into three groups as tertiary referral centers, state hospitals and private practice hospitals. The number of outpatients, inpatients, daily interventions and urological surgeries were recorded prospectively between 9-March-2020 and 31-May-2020. All these variables were recorded for the same time interval of 2019 as well. The weekly change of the workload of urology during pandemic period was evaluated; also the workload of urology and the distributions of certain urological surgeries were compared between the pandemic period and the same time interval of the year 2019. Results: A total of 51 centers participated in the study. The number of outpatients, inpatients, urological surgeries and daily interventions were found to be dramatically decreased by the third week of pandemics in state hospitals and tertiary referral centers; however the daily urological practice were similar in private practice hospitals throughout the pandemic period. When the workload of urology in pandemic period and the same time interval of the year 2019 were compared; a huge decrease was observed in all variables during pandemic period. However, temporary measures like ureteral stenting, nephrostomy placement and percutaneous cystostomy have been found to increase during Covid-19 pandemic compared to normal life. Conclusions: Covid-19 pandemic significantly effected the routine daily urological practice likewise other subspecialties and priority was given to emergent and non-deferrable surgeries by urologists in concordance with published clinical guidelines.

Aim: A worldwide pandemic of coronavirus disease 2019 (COVID-19) which emerged in China in December 2019 affects the world very seriously. We aimed to evaluate the benign prostatic hyperplasia (BPH) patients who were admitted and treated to our hospital due to COVID-19. Methods: Between March 18, 2020 and April 5, 2020 , 18 patients admitted with COVID-19 who has BPH and are using medication for this were included in the study and analyzed retrospectively. Diagnosis was confirmed by COVID-19 nucleic acid test by sampling sputum or nasopharyngeal swab. Standard COVID-19 treatment protocol determined by our Ministry of Health was applied to all patients according to their risk groups. Epidemiological, clinical, radiological features, additional diseases, laboratory tests, complications and outcome data of all patients were recorded. Results: Mean age of patients was 59.6 (range: 56-73). As the mode of transmission, 10 (55.5%) of patients were infected in hospital, 5 (27.7%) patients had a relative with COVID-19 and 3 (16,6%) was unknown. During follow-up, 2 (11.1%) patients were transferred to intensive care unit (ICU). One of these patients dramatically progressed and died. Patients who survived and were not transferred to ICU had lesser comorbidities and were relatively young. Mean duration of hospitalization was 14.2 days (range 12-19). Conclusion: We think that COVID-19 patients with BPH had a low mortality rate and did not have a poor prognosis in this patient group. It is crucial to take comprehensive preventive measures to control COVID-19 transmission via hospital route.
