Aim: Learned bodies recommended restricted use of, or extensive precautions when using, laparoscopic/robotic surgery during the Covid-19 pandemic. We aimed to determine whether minimally invasive surgery (MIS) in uro-oncology patients was safe for patients and staff. Method: From 16 March to 16 June 2020, patients having MIS in a tertiary referral urology centre were identified from a prospectively collected database. Patient characteristics, operative details and 30-day follow-up for adverse events were recorded including Covid-19 tests and results. Any theatre staff Covid-19 event was traced back 14 days to determine any involvement in these cases. Results: 87 patients were eligible for inclusion (33 robotic prostatectomies, 38 laparoscopic prostatectomies, 11 laparoscopic nephrectomies, 5 robotic nephrectomies). All patients were assessed for symptoms of Covid-19 on the day of theatre. 18(21%) patients had pre-operative screening (all swabs, no CT chest). 46(53%) underwent 14 days pre-operative self-isolation. 38(44%) cases were performed with FFP3 protection. No modification to operating procedure was made for any cases. No patients tested positive for Covid-19 in the 30-day postoperative period. No staff member involved tested positive in the postoperative period. 1 patient tested positive pre-operatively, delaying the operation by 7 weeks. No patients tested positive after the introduction of mandatory screening. Conclusions: Based on our case-series MIS urological surgery appears to be safe for patients and staff, with no increased risk of Covid-19 complications in patients who are asymptomatic pre-operatively. The introduction of mandatory pre-operative swabs for elective patients, and the use of FFP3 protection, did not significantly alter results.

The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can result in a hyperinflammatory state, leading to acute respiratory distress syndrome (ARDS), myocardial injury, and thrombotic complications, among other sequelae. Statins, which are known to have anti-inflammatory and antithrombotic properties, have been studied in the setting of other viral infections and ARDS, but their benefit has not been assessed in COVID-19. Thus, we sought to determine whether antecedent statin use is associated with lower in-hospital mortality in patients hospitalized for COVID-19. This is a retrospective analysis of patients admitted with COVID-19 from February 1 st through May 12 th , 2020 with study period ending on June 11 th , 2020. Antecedent statin use was assessed using medication information available in the electronic medical record. We constructed a multivariable logistic regression model to predict the propensity of receiving statins, adjusting for baseline socio-demographic and clinical characteristics, and outpatient medications. The primary endpoint included in-hospital mortality within 30 days. A total of 2626 patients were admitted during the study period, of whom 951 (36.2%) were antecedent statin users. Among 1296 patients (648 statin users, 648 non-statin users) identified with 1:1 propensity-score matching, demographic, baseline, and outpatient medication information were well balanced. Statin use was significantly associated with lower odds of the primary endpoint in the propensity-matched cohort (OR 0.48, 95% CI 0.36 a" 0.64, p<0.001). We conclude that antecedent statin use in patients hospitalized with COVID-19 was associated with lower inpatient mortality. Randomized clinical trials evaluating the utility of statin therapy in patients with COVID-19 are needed.
