Giant Hydronephrosis in Crossed Renal Ectopia without Fusion

Giant hydronephrosis in a solitary crossed ectopic kidney

“…Abeshouse (1947) found associated renal pathology in 204 of 337 cases of crossed renal ectopia, while Abeshouse and Bhisitkul (I959), in a series of 55 cases of crossed renal ectopia, discovered an associated lesion in 30 (55 per cent). The occurrence of 3 examples of giant hydronephrosis arising in crossed renal ectopia without fusion (Malament and Majnarich, 1960;Pathak, 1965;Hurley, Clery, and Kelly, 1969) is of particular interest in relation to the present case. I n each case the crossed ectopia involved the left kidney, which occupied the usual inferior position relative to the right kidney, and stenosis or stricture of the pelviureteric junction was evident as the cause of the hydronephrosis.…”

“…The kidney was drained with a nephrostomy tube. (Malament and Majnarich, 1960). The varieties of crossed renal ectopia have been classified by Amesur and Singh (1963), crossed fused ectopia with the ectopic kidney in the inferior position being the most common type.…”

Crossed Renal Ectopia

“…crossed renal ectopia is very rare. The only case is that reported by Malament and Majnarich (1960), the kidney containing 1,500 ml. of soft clotted dark material.…”
