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

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.
