Successful management of ectopic kidney stones in a patient with situs inversus totalis: a rare case report

BACKGROUND: Situs inversus totalis is a very rare congenital anatomical variation, in which all thoracic and abdominal organs are right-left inverted. This condition is associated with an increased risk of organ malformations including ectopic kidney, which is a very rare combination. CASE PRESENTATION: A 56-year-old male presented with colicky left iliac pain associated with nausea, vomiting, and irritative lower urinary symptoms. The patient has a medical history of recurrent lower urinary infections and a family history of situs inversus totalis. Radiological images demonstrated dextrocardia, situs inversus totalis of all the abdominal organs, and an ectopic pelvic kidney on the left side, with 4 stones inside it. Left nephrectomy was performed due to extensive renal damage. At discharge and during follow-up, the patient's condition was satisfactory and stable. CONCLUSIONS: The ectopic kidney may present diagnostic and therapeutic challenges when associated with situs inversus.
