Background Ultrasound malformations of the fetal genitourinary tract are well documented in the sonographic literature. However, we would like to report on some specific observations. These will include a survey of fetal pelvic kidneys, an association between single umbilical artery (SUA) and absence of one of the kidneys, and the ‘Tulip sign’– an ultrasonic marker for severe penoscrotal hypospadias. Method All records of patients with ectopic kidneys over a 5‐year period (1995–99) have been perused. Sonographic parameters of ectopic kidney have been evaluated. The same was done for cases of SUA and agenesis of one kidney and for cases with severe penoscrotal hypospadias. Results Pelvic kidney was diagnosed prenatally in 35 cases, of which, bilateral pelvic kidney was detected in 2 cases. There was no predilection for fetal gender, and no tendency to side of appearance. Most cases were diagnosed in late 2nd trimester of pregnancy. The association of SUA and absent kidney was detected in 6 cases. In all cases the diagnosis was made in the 2nd trimester of pregnancy. In 6 cases, the specific ‘Tulip sign’ was detected prenatally and proven postnatally. Conclusions Unique presentations of renal anomalies can be detected prenatally. Pelvic kidney is easily dealt with, however, the association of SUA and absent kidney requires further evaluation of the fetus to exclude the VATER association. The ‘Tulip sign’ is helpful in diagnosing severe hypospadias.
