There are indeed numerous variables to take into consideration with performance and
interpretation of a VCUG, especially with the diagnosis of posterior urethral valves.
In the current study, the ratios were measured under specific filling and voiding
circumstances to reduce the possibility of an erroneous calculation on account of
these dynamic factors. We agree that such calculations leave room for variability
and can be vulnerable to lack of precision. If the VCUG fails to demonstrate adequate
conditions to properly assess the ratios, a fallacious ratio will result.

- Editorial comment on “Posterior urethral morphology on initial voiding cystourethrogram correlates to early renal outcomes in infants with posterior urethral valves”Journal of Pediatric UrologyVol. 18Issue 6
- PreviewIn this interesting paper, the authors have studied the bladder height to width ratio (HW-B), posterior urethral height to width ratio (HW-PU), posterior-anterior urethral ratio (PA-UR) and bladder trabeculation grade on initial voiding cystourethrogram (VCUG) of children with posterior urethral valve (PUV) and found that only HW-PU significantly correlated with a higher nadir creatinine at one-year of age [1]. Niyogi [2] proposed that in children with PUV increasingly distorted bladder shape was associated with poor bladder dynamics and proposed shape, wall, reflux and diverticuli (SWRD) score.
