Urinary stone management during the COVID-19 pandemic: a suggested approach and review of literature

COVID-19 is now the major health concern of the century in many countries. Prolonged homestay has various undesirable consequences for people, such as physical inactivity and weight gain, which potentially could put people at risk of urinary stone formation. With regard to the prevention and treatment strategy for urinary stones during this COVID-19 pandemic period, patients can be divided into two groups. The first group comprises those for whom urological intervention is not indicated and where general dietary and lifestyle recommendations are helpful. The second group comprises those patients where urological intervention is indicated. This group can be divided into emergent and nonemergent subgroups. Patients with urinary stones and concomitant uremia, sepsis, anuria, or refractory pain and vomiting make up the emergent group, where intervention is necessary. The preferred option during the novel coronavirus crisis for these patients is percutaneous nephrostomy tube insertion under local anesthesia. The second subgroup is made up of those patients with asymptomatic and noncomplicated renal and ureteral stones where urologic intervention is indicated in the usual time scale. However, we suggest conservative treatment for 3 months during the COVID-19 outbreak after which re-evaluation of the patient should be carried out. Thus the operation could be chosen carefully based on the patient's and urologist's preference and the rate of infection in that center.
