Editorial comment on “Posterior urethral morphology on initial voiding cystourethrogram correlates to early renal outcomes in infants with posterior urethral valves”

Abstract

In 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.
