[Presacral kidney].
The ectopic kidney in the presacral position can occur in 1 of 800 subjects. This condition results from metanephrogenic anomalies during the embryological development. When urographic images of the kidney are absent, one should always suspect this condition. In most of the cases, this condition does not cause a disorder and are incidentally detected while performing other studies for other disorders. A normally functioning presacral kidney requires no treatment.
