ABSTRACTIntroduction: Obstruction of uretero-pelvic junction is the most common etiology of hydronefrosis in children. The objective of this study is analyze clinical presentation, diagnosis, treatment and expose standards of diag-nosis and management of this pathology.
Material and methods: This is a retrospective study of 175 children with uretero-pelvic junction obstruction, treated over a period of 13 years. The analyzed data were: Age at initial presentation, sex, side affected, signs and symptoms, associated congenital anomalies, transient procedures done prior to definitive treatment, diagnosis workup, type of reconstruction, complications and final outcome.
Results: There were 105 left, 46 right and 24 bilateral kidneys affected for a total of 199. Treatment consisted of an Anderson-Hynes pieloplasty in 92%, reinter-vention or balloon dilatation in 3.5% and simple nephrectomy in the rest (4.5%). The final outcome was considered good in 91.9% and bad in 8.1% patients (-1 year age), nefrostomy was employed by renal function -10% and the others pieloplasty. In all of them the renal function improved between 10 and 20%.
Conclusion: With detection and early management we have kidneys unaffected. The surgery, in patients -1 year age, improved the renal function, and in olders only the lesion will be limited.
