Pelvic Kidney
Synonyms/Description
Ectopic location of kidney—normal variant
Etiology
The incidence of pelvic kidney is reported as being between 1 in 2200 and 1 in 3000. The normal human kidney migrates to the renal fossa from a pelvic location early in embryonic development, typically before the 10th week of gestation. The congenital failure of this migration results in a pelvic kidney. Although a pelvic kidney is defined as a normal variant, it is associated with Müllerian duct anomalies such as uterine malformation (see Müllerian Duct Anomalies ). Pelvic kidney is the most common type of renal ectopia and is typically clinically asymptomatic. However, ectopically located kidneys are at increased risk of urinary tract infection, stone formation, and trauma.
