Consensus Statement on Urinary Stone Treatment During a Pandemic: A Delphi Process from the Endourological Society TOWER Research Initiative.

The novel coronavirus disease (COVID-19) pandemic has had a significant impact on the care of patients with urolithiasis. Recommendations and prioritization of endourologic surgical procedures vary among regions, and a comprehensive overall international directive is needed. We used the Delphi method to obtain international consensus on managing urolithiasis patients during the pandemic. A three-round Delphi process was used to elicit expert consensus (53 global key opinion leaders within the Endourological Society from 36 countries) on an extensive survey on management of endourologic patients in a pandemic. Questions addressed general management, inpatient and outpatient procedures, clinic visits, follow-up care, and best practices for suspension and resumption of routine care. Consensus was achieved in 64/84 (76%) questions. Key consensus findings included the following: consultations should be delivered remotely when possible. Invasive surgical procedures for urolithiasis patients should be reserved for high-risk situations (infection, renal failure, etc.). To prevent aerosolization, spinal anesthesia is preferred over general, whenever feasible. Treatment of asymptomatic renal stones should be deferred. Primary definitive treatment of obstructing or symptomatic stones (both renal and ureteral) is preferred over temporizing drainage. Extracorporeal shockwave lithotripsy should be continued for obstructive ureteral stones. There was consensus on treatment modalities and drainage strategies depending on location and size of the stone. International endourologist members of the Endourological Society participated in this Delphi initiative to provide expert consensus on management of urolithiasis during a pandemic. These results can be applied currently and during a future pandemic.
