ARTICLE HIGHLIGHTS
Research background

Ureteropelvic obstruction is a common pediatric condition, which can be due to congenital internal obstruction or external obstruction secondary to crossing vessels. This study aims to encourage the use of dynamic contrast-enhanced magnetic resonance urography (dMRU) as a modality, measuring renal function as effectively as 99m-technetium mercaptoacetyltriglycine (MAG-3) and providing a good anatomical study in cases of obstruction due to crossing vessels.

Research motivation

dMRU proves advantageous as an alternative modality for ureteropelvic junction obstruction (UPJO). However, enhanced accessibility and cost-effectiveness can be achieved through advancements in magnetic resonance imaging technology.

Research objectives

The optimal imaging modalities for preoperative functional and anatomical assessment of UPJO in pediatric patients.

Research methods

Analysis of data in patients who underwent surgery for UPJO and had both dMRU and scintigraphy MAG-3 for split renal function assessment.

Research results

dMRU is equivalent to scintigraphy MAG-3 for evaluating split renal function in UPJO cases of all pediatric age groups. Future implications emphasize the need for larger multicenter studies to confirm findings, while advancements in imaging technology hold promise for enhancing the accessibility and viability of dMRU as a gold standard diagnostic tool of UPJO.

Research conclusions

dMRU is an excellent alternative modality for the anatomical and functional evaluation of children with UPJO. A large sample size is required to confirm this hypothesis.

Research perspectives

To enhance the accessibility and viability of dMRU.
