# Pyeloureteral Junction Syndrome in a Neonate With a Solitary Kidney Treated by Anderson-Hynes Pyeloplasty: A Case Report

## TL;DR

A neonate with a solitary kidney and hydronephrosis was successfully treated with Anderson-Hynes pyeloplasty, highlighting the importance of early intervention to prevent kidney failure.

## Contribution

The study provides insights into the clinical management and outcomes of Anderson-Hynes pyeloplasty in neonates with a solitary kidney.

## Key findings

- Anderson-Hynes pyeloplasty effectively treated hydronephrosis in a neonate with a solitary kidney.
- Early surgical intervention is crucial to prevent progressive renal fibrosis and failure.
- Pyeloureteral junction obstruction can be a standalone issue or part of a broader condition.

## Abstract

A rare disorder called newborn hydronephrosis is mostly caused by the obstruction of the pyeloureteral junction. We describe a case study of a male neonate who underwent Anderson-Hynes pyeloplasty to effectively cure hydronephrosis in a single kidney that was further complicated by early renal failure.

Considering kidney failure can result in progressive renal fibrosis, early management is essential. The gold standard is Anderson-Hynes pyeloplasty, which is usually advised for individuals who weigh over 10 kg. Percutaneous nephrostomy is frequently used in the early stages of care for newborns in order to reduce dilatation and restore renal elasticity. After surgery, the resolution of hydronephrosis may take up to 24 months. We note that pyeloureteral junction obstruction can appear as a single anomaly or a component of a multifactorial illness.

This study aims to contribute to the discourse surrounding the optimal timing of Anderson-Hynes pyeloplasty in pediatric patients, providing insights into clinical management strategies and outcomes.
