“…The phallic abnormalities were not recorded on ultrasound examination in any of the cases, probably due to poor visualization. The monozygotic twins concordant for CDS (cases 5 and 6) and the case of CDS with ultrasonographically demonstrated intestinal calcifications (case 4) have been previously reported [12,13].…”

Cloacal dysgenesis sequence (CDS) is a rare cause of fetal obstructive uropathy (FOU). The prenatal differentiation of CDS from other FOU is important because CDS is not amenable to in utero surgical intervention in the form of vesicoamniotic shunts. We evaluated the prenatal characteristics of 8 fetuses with CDS, including a pair of monozygotic twins concordant for CDS, in order to identify features that would enable differentiation from other forms of FOU. Pathologic examination in each of the 8 fetuses confirmed characteristic features of absent anal, genital, and urinary orifices associated with a smooth perineum and abnormal phallic development. Associated abnormalities included dysplastic kidneys in 6, hydroureters in 5, intraluminal colonic calcifications in 2, and hypoplastic lungs in 5. Five of these fetuses initially presented as posterior urethral valve syndrome. Six fetuses had megacystis, and 4 underwent vesicocenteses to evaluate urinary electrolytes, all of which were in the ‘poor-risk’ category. Six fetuses were male and 2 female, contradicting earlier claims that CDS occurs only in females. Evaluation of candidates for in utero surgical intervention should include fetal karyotype, and CDS should be suspected in cases of FOU in whom the karyotype reveals a male fetus and sonographic evaluation demonstrates colonic calcifications or abnormal phallic development. Diagnostic microendoscopy may be of benefit in such cases.

“…It has been suggested that prolonged stasis, and especially, the interaction between urine and meconium, play a critical role (Anderson et al, 1988;Sepulveda et al, 1994). This mechanism, however, could not be implicated in our case, because no abnormal mixture of urine and meconium occurred.…”

“…Prenatal ultrasonographic diagnosis of fetal enterolithiasis (intra-luminal calcified meconium) has previously been described in seven cases, all of whom were associated with major gastro-intestinal and genito-urinary malformations (Anderson et al, 1988;Sepulveda et al, 1994). We describe a case of fetal anhydramnios and enterolithiasis in a structurally-normal fetus that on post-mortem examination, was found to have end-stage liver disease.…”

“…Five cases had a fistula between the anorectum and the urinary tract, and in all cases genito-urinary malformations coexisted, resulting in oligohydramnios in four cases, and anhydramnios in one (Sepulveda et al, 1994).…”
