“…However, in the study by Kumano et al for instance, the specificity of height to width ratio was low at 59% and there was no significant difference in maximum bladder volume between high-pressure and low-pressure bladders. Babu et al have also recently published a study on height to width ratio in boys with posterior urethral valves with interesting results, though as opposed to neurogenic bladders, the actual scope of bladder anomalies in PUV patients is wider ( 11 ). The study by Wu et al looked at various parameters such as height to width ratio of the bladder (HW-B), height to width ratio of the posterior urethra (HW-PU), posterior-anterior urethral ratio (PA-UR), bladder trabeculation grade, and presence/laterality of vesicoureteral reflux on early cystograms, but found that only HW-PU was related to nadir creatinine ( 12 ).…”

IntroductionBladder profile in boys with Posterior Urethral Valves can be very varied with a spectrum going from high pressure, unstable, hypocompliant small bladders to hypercompliant, large acontractile bladders, with some being near-normal. Our question was whether appearance, specifically of the bladder, on initial VCUG was correlated to prenatal features and whether it could predict early postnatal outcome.MethodWe used a prospectively gathered database of boys with prenatally suspected PUV. We analyzed whether the appearance, specifically of the bladder, was related to date of prenatal diagnosis, presence of a megacystis on prenatal ultrasound, presence of vesico-ureteral reflux (VUR), presence of abnormal DMSA scan, nadir creatinine or presence of febrile urinary tract infection (fUTI) during the first two years of life.ResultsThe database comprised 90 cystograms. 15% of bladders were judged normal/regular, 54 % were small/diverticular and 31% were large/diverticular. Bladder appearance was not associated with presence of prenatal megacystis, abnormal DMSA scan, VUR, nor rate of fUTI. The only significant associations were normal/regular bladder and early prenatal diagnosis (p = 0.04) and normal/regular bladder and elevated nadir creatinine (>75µmol/l) (p = 0.01).DiscussionWe believe that when focusing solely on the appearance of the bladder, excluding information about the urethra and presence of reflux, the cystogram alone is insufficient to inform on future bladder function. This could be used as an argument in favor of performing early urodynamics in this population.
