Congenital ureteropelvic junction obstruction (UPJO) was a common cause of congenital hydronephrosis,and Anderson-Hynes dismembered pyeloplasty was considered the gold standard for treating UPJO.Although clinical guidelines provide clear indications for surgery,early surgical timing remains controversial due to factors such as the small size of infants and the ongoing development of their kidneys.This paper primarily explores the surgical indications,controversies surrounding early surgical timing,and surgical techniques to explore the timing of surgery and treatment strategies for hydronephrosis caused by congenital UPJO in infants.
