Perioperative outcomes of patients undergoing urological elective surgery during the COVID-19 pandemic: a national overview across 28 Italian institutions.

The aim of this study was to assess the safety of elective urological surgery performed during the pandemic by estimating the prevalence of COVID-19-like symptoms in the postoperative period and its correlation with perioperative and clinical factors. In this multicenter, observational study we recorded clinical, surgical and postoperative data of consecutive patients undergoing elective urological surgery in 28 different institutions across Italy during initial stage of the COVID-19 pandemic (between February 24 and March 30, 2020, inclusive). A total of 1943 patients were enrolled. In 12%, 7.1%, 21.3%, 56.7% and 2.6% of cases an open, laparoscopic, robotic, endoscopic or percutaneous surgical approach was performed, respectively. Overall, 166 (8.5%) postoperative complications were registered, 77 (3.9%) surgical and 89 (4.6%) medical. Twenty-eight (1.4%) patients were readmitted to hospital after discharge and 13 (0.7%) died. In the 30 days following discharge, fever and respiratory symptoms were recorded in 101 (5.2%) and 60 (3.1%) patients. At multivariable analysis, not performing nasopharyngeal swab at hospital admission (HR 2.3; CI 95% 1.01-5.19; p = 0.04) was independently associated with risk of developing postoperative medical complications. Number of patients in the facility was confirmed as an independent predictor of experiencing postoperative respiratory symptoms (p = 0.047, HR:1.12; CI95% 1.00-1.05), while COVID-19-free type of hospitalization facility was a strong independent protective factor (p = 0.02, HR:0.23, CI95% 0.07-0.79). Performing elective surgery during the COVID-19 pandemic does not seem to affect perioperative outcomes as long as proper preventive measures are adopted, including nasopharyngeal swab before hospital admission and hospitalization in dedicated COVID-19-free facilities.
