Hydronephrosis due to pelviureteric junction obstruction in infancy

Area of Science:

• Pediatric Urology
• Nephrology
• Radiology

Background:

• Hydronephrosis is a common condition in children.
• Pelviureteric junction obstruction is a primary cause of pediatric hydronephrosis.
• Long-term outcomes of surgical correction require ongoing evaluation.

Purpose of the Study:

• To evaluate the long-term outcomes of treating pediatric hydronephrosis caused by pelviureteric obstruction.
• To assess the utility of 197Ce2 scintigraphy in evaluating renal function post-treatment.
• To identify any significant changes in renal function from early to late post-operative periods.

Main Methods:

• Retrospective review of 31 pediatric cases treated over 12 years.
• Analysis of early and late post-operative urograms.
• Utilized 197Ce2 scintigraphy for renal function assessment.

Main Results:

• No significant changes observed between early and late post-operative urograms.
• 197Ce2 scintigraphy demonstrated utility in assessing renal function.
• Two secondary nephrectomies were performed; no primary nephrectomies.
• Contralateral anomalies were noted in a significant number of cases.

Conclusions:

• Surgical treatment for pelviureteric junction obstruction in children yields stable long-term results.
• 197Ce2 scintigraphy is a valuable tool for monitoring renal function after hydronephrosis treatment.
• Further research is needed to confirm long-term stability into adulthood.
