Abstract
Renal ectopia anatomically results from altered migration of kidneys to their normal position in the lumbar region. Few case reports have been reported in literature. Visceral-tissue variation was in form of quadratus lumborum and psoas major in place of the RT kidney. A 21 year old female with positive HCG (pregnancy test) presented for radiological (ultrasound) confirmation of cyesis, though no sonic evidence of gravidae was observed (< 5 wks GA); confirmatory ectopic kidney was diagnosed on completion of ultrasound. This report underscores the importance of imaging the RT groin and illiac region before surgical intervention thus preventing iatrogenic injury genesis. Treatment of this condition will depend on the functional capacity of the kidney, while nephrectomy is recommended for ‘static’ non-functional kidneys. Non-complicated cases and anatomic variation can be managed conservatively.
Highlights
The fetal kidneys during early development first appear as buds inside the pelvis which later ascend to the lumbar region
Individuals with renal ectopia usually have incidents of increased urinogenital anomalies[14], cryptorchidism or urethral duplications can be seen in males
As a consequence of RT renal ectopia [Figure 1 and 3], no evidence of hepatic depression was seen on sonar
Summary
The fetal kidneys during early development first appear as buds inside the pelvis which later ascend to the lumbar region. It is reported that thoracic or renal ectopia may be congenital or acquired, rarely occurs bilaterally and occurrence is mostly in males with preponderance at the left lateral side.[1,2] Sparse record of ectopic kidney as been reported in South-West Nigeria; Ilah et al[3] 2015 documented rare statistical prevalence.
