Insights
This case report details megacalycosis in a child, diagnosed at age four. Surgical intervention for pyeloureteral stenosis led to a normal clinical and scintiscan outcome after four years.
Area of Science:
- Pediatric Urology
- Nephrology
- Surgical Case Reports
Background:
- Megacalycosis is a rare congenital renal anomaly characterized by enlarged renal calyces.
- Early diagnosis and management are crucial for preventing complications such as obstruction and infection.
- This report focuses on a pediatric case with superimposed pyeloureteral junction obstruction.
Observation:
- A nine-and-a-half-year-old male presented with severe colic pains.
- Isotopic renogram indicated obstruction unresponsive to seguril, suggesting superimposed stenosis.
- Diagnosis of megacalycosis with pyeloureteral stenosis was confirmed.
Findings:
- The patient underwent an Anderson-Hynes pyeloplasty for the obstruction.
- Post-operative follow-up at four years showed complete resolution of symptoms.
- Clinical examination and scintiscan confirmed normal renal function and anatomy.
Implications:
- This case highlights the successful surgical management of megacalycosis with superimposed pyeloureteral stenosis in a pediatric patient.
- Anderson-Hynes pyeloplasty is an effective treatment for this specific condition.
- Long-term follow-up confirms the durability of surgical repair and normal renal outcomes.
Abstract:
Contribution of a case report of megacalycosis in a nine and a half-year old male child, in whom the disorder was diagnosed by our team when he was only four. The intense colic pains experienced by the child together with the isotopic renogram non responsive to seguril typical of obstruction, raised the diagnosis of superimposed stenosis of the pyeloureteral attachment. As a result, an Anderson-Hynes pyeloplasty was performed. Post-operative status after four years is absolutely normal from both a clinical and scintiscan point of view.
