Ectopic kidney: a rare case presentation
Keywords:Ectopic kidney, Umbilical, Calculi, Nephrectomy
The ectopic kidneys are a rare developmental disorder. The ectopic kidneys are the result of the cessation of normal migration. The incidence of ectopic kidney is 1/12,000 clinical cases and 1/900 post-mortem cases. Such kidneys may be asymptomatic, show vague symptoms, or remain undetected for life. However, early detection of ectopic kidneys can prevent long-term complications. Here were present a case of 17-year-old adolescent with an ectopic kidney presented with an episode of intermittent pain in her left umbilical region for one year. A physical examination revealed a tender lump in the umbilical region of the abdomen. The USG showed a mass on the left side of the umbilical region, which could be an ectopic kidney. Computer tomography showed an ectopic kidney in the midline of the umbilical region. In addition, DTPA scans of the kidney showed that the left kidney showed inadequate function with delayed upper inflow tract. Urinalysis revealed urinary tract infection. Patient had mild degree of anaemia with low serum iron levels. The ectopic kidney was removed and sent to us in our lab. Histo-pathological examination was done and it revealed normal parenchyma of kidney. Ectopic kidneys should be included in the differential diagnosis in patients with abdominal pain and palpable lump in the abdomen. Early detection can prevent long term complications.
