Abstract

The best surveillance method, timing and frequency to outline resolution of obstruction in children after pyeloplasty are not yet defined.
To assess the correlation between post-operative diuretic scintigraphic and ultrasonographic parameters in children who underwent pyeloplasty.
In a single arm prospective cohort study, 83 children who underwent open Anderson-Hynes pyeloplasty from June 2023 to May 2024, were included. Those who had bilateral pyeloplasty or pyeloplasty in a solitary or anomalous kidney were excluded. Six months after surgery, follow-up ultrasonography and diuretic scintigraphy were performed.
Successful pyeloplasty was noted in 81 patients (97.59 %), while the remaining 2 patients (2.41 %) who had failed pyeloplasty were managed by redo pyeloplasty. Pre and post-operative ultrasonographic and scintigraphic parameters were evaluated in all patients. Post-operative cortical transit time (CTT) showed significant correlation with post-operative anteroposterior diameter (APD), parenchymal thickness, calyceal dilation, calyx-to-parenchyma ratio, cortex-to-pelvis ratio and T-half (T½). Post-operative T½ also showed significant correlation with post-operative APD, parenchymal thickness, calyx-to-parenchyma ratio and cortex-to-pelvis ratio. On the other hand, post-operative CTT showed insignificant correlation with APD change, while post-operative T½ showed insignificant correlation with APD change and post-operative calyceal dilation.
Post-operative ultrasonographic parameters, apart from APD change and post-operative calyceal dilation, may correlate with post-operative diuretic scintigraphic parameters in children who underwent pyeloplasty.
