Isolated rupture of renal pelvis after blunt chest trauma: First description of a case

Isolated post-traumatic rupture of renal pelvis (IPTRRP) is an extremely rare condition and only a few cases following blunt abdominal trauma have been reported in the literature.To our knowledge, no cases of IPTRRP following blunt chest trauma have been reported.We present the case of an 84-year-old woman who was admitted to our Emergency Department due to persistent left flank pain that started after she had fallen to the ground 4 days before, with blunt trauma on her chest.CT showed a rupture of the left renal pelvis with contrast extravasation, associated with multiple rib fractures. No renal and other parenchymal injuries were detected.The patient was managed conservatively with the implantation of a ureteral stent and discharged in good clinical conditions.Our case shows the first description that IPTRRP might be an uncommon but possible complication of blunt chest trauma and must be included in the differential diagnosis.
