Analysis of the Efficacy of Elastography in Comparison with Dynamic Renal Nuclear Scintigraphy in the Evaluation of Unilateral Pelvi–Ureteric Junction Obstruction

jpedsurg.org

In hydronephrosis due to pelviureteric junction obstruction (PUJO), an obstruction to urine flow may lead to increased pelvic pressure, which may cause interstitial fibrosis and renal impairment. Recently, there have been reports on renal pelvic assessment using ultrasound elastography (USE). This study was conducted to see if USE can evaluate PUJO and if it can be correlated to the findings of the dynamic renal nuclear scan.

In brief

This study evaluates ultrasound elastography as a diagnostic tool for pelviureteric junction obstruction, comparing its efficacy against dynamic renal scintigraphy. The research investigates whether elastography can detect interstitial fibrosis and renal impairment caused by obstructed urine flow in hydronephrosis cases.

Pelviureteric junction obstruction causes increased pelvic pressure leading to interstitial fibrosis and renal impairment.
Ultrasound elastography is emerging as a non-invasive tool to assess renal pelvic changes in PUJO.
USE findings may correlate with dynamic renal nuclear scan results, offering a radiation-free alternative for evaluation.
