In their letter to the editor, Arnaud et al. agree with our conclusion about the importance
of being consistent in using the same method of APD measurement while evaluating/following
up children with postnatal hydronephrosis, as this could significantly affect clinical
decision making. For example, if we measure the APD at the inner pelvis and in the
subsequent follow up the APD is measured at the extrarenal pelvis, this could lead
to a false impression of increasing hydronephrosis when in fact the hydronephrosis
may be stable. This could lead to unnecessary invasive diagnostic investigations and
increased parental and caregiver anxiety. This type of scenario is most likely to
occur when sequential ultrasound studies are done at different institutions.

- Comment to: “How can we measure the renal pelvic anteroposterior diameter in postnatal isolated hydronephrosis? Amr Hodhod, Hadeel Eid, John-Paul Capolicchio, Francis Petrella, Iman Sadri, Mohamed El-Sherbiny, Roman Jednak, Caroline Lacroix”Journal of Pediatric UrologyVol. 19Issue 1
- PreviewWe read with great interest the study by Dr Hodhod et al. who compared six different techniques for measuring anteroposterior diameter (APD) of the renal pelvis [1]. They found little difference in APD according to patient position, but did find a significant difference between intrarenal, renal contour and extrarenal APD.
