Fetal bladder histology in posterior urethral valves and the prune belly syndrome
SJ Workman, BA Kogan - The Journal of Urology, 1990 - Elsevier
Bladder histology was reviewed in fetuses with posterior urethral valves and the prune belly
syndrome, and compared with that of controls. Fetuses with posterior urethral valves had
increased muscle thickness (1.7±0.3 versus 0.9±0.2 mm.) and a slightly increased ratio of
connective tissue (38±6 versus 31±7%). Those with the prune belly syndrome fell into 2
groups: 1 had anatomical evidence of obstruction, increased muscle thickness and a normal
ratio of connective tissue (2.2±6 mm. and 28±9%), while 1 had no evidence of obstruction …
