Urethral atresia and anhydramnios at 18 weeks of gestation can result in normal development
Journal of Pediatric Urology, 05/15/2012
Stalberg K et al. – A 28–year–old gravida II had anhydramnios at 17 weeks. At 19 weeks, the bladder measured 12 cm, and karyotype was XY. At 21 weeks, a fistula between the bladder and the amniotic space developed. At 36 weeks, a 2800 g boy with prune belly phenotype was delivered. There was a completely obstructing membrane below the veru montanum and a hypoplastic urethra distal to it. Resolution of anhydramnios at 21 weeks of gestation can result in normal pulmonary function and acceptable renal and bladder function in childhood. Efforts to develop effective methods of fetal bladder decompression should continue.
