Crossed fused ectopic kidney in a patient with irritable bowel syndrome with diarrhea: a case report

Abstract

<p>Irritable bowel syndrome (IBS) is the most commonly diagnosed gastrointestinal condition that reduces patients' quality of life. It has multifactorial etiology. Nowadays it is thought that more than one etiologic factor may contribute to heterogeneous symptoms of IBS. Crossed fused ectopic kidney is a condition where both kidneys are situated on one side and fused and drain bilaterally into the urinary bladder. Most often, it is discovered by chance when evaluating another illness. A drum-shaped bulge was discovered in the descending colon of an 18-year-old girl during the examination of a protracted period of abnormal bowel habits in the form of diarrhea, with normal overlying mucosa. On additional examination, an abdominal CT scan revealed that she had a fused left renal ectopia and an empty right renal fossa. In most of the crossed fused renal ectopia (CFRE) cases patient remains asymptomatic; in a few cases it is associated with renal agenesis, vascular malformation, incontinence, a palpable abdominal mass, urinary tract infection, high incidence of stone formation, and genital anomalies. In this case report, we emphasize on crossed fused kidney causes an external compression to the intestinal wall which may create increased visceral hypersensitivity resulting in irritable bowel syndrome with diarrhea (IBS-D) type symptoms.</p>
