Spontaneous severe retroperitoneal hemorrhage with concomitant renal pelvis rupture during the course of COVID-19 infection: a case report

Spontaneous rupture of the renal pelvis is a rarely encountered urological event that causes extravasation of urine. It often occurs as a result of increased intrapelvic pressure secondary to obstructions developed in the urinary system. Similarly spontaneous retroperitoneal hematoma is retroperitoneal hemorrhage that occurs without trauma or an underlying pathology. In this study, we present a case of spontaneous rupture of the renal pelvis that developed secondary to compression of the hematoma that occurred spontaneously in the retroperitoneum in a 63-year-old female patient who received anticoagulant therapy with the diagnosis of Covid-19 infection. In the light of this case, we would like to emphasize that widespread endothelial cell damage associated with Covid-19 infection may cause spontaneous severe retroperitenal bleeding and accompanying renal pelvis rupture. In which both the rarely encountered spontaneous rupture of the renal pelvis and spontaneous retroperitoneal bleeding are seen simultaneously in the same patient, is reporting for the first time in the literature.
