Summary
Infundibulopelvic stenosis is a rare kidney malformation in children. This study found it has characteristic radiographic features and a good prognosis for most affected patients.
Area of Science:
- Pediatric Radiology
- Nephrology
- Congenital Malformations
Background:
- Infundibulopelvic stenosis is a rare renal malformation.
- This condition is characterized by caliceal dilatation, infundibular stenosis, and renal pelvis hypoplasia or stenosis.
Observation:
- Excretory urography identified three cases of infundibulopelvic stenosis in 11,500 children over 17 years.
- Renal sonography revealed caliceal dilatation without pelvic dilatation; voiding cystourethrograms were normal.
- Retrograde ureteropyelography confirmed the diagnosis in one patient.
Findings:
- Two patients with infundibulopelvic stenosis remained asymptomatic with normal renal function and stable sonographic findings over 12-18 months.
- The contralateral kidney was absent in two cases and normal in one.
- The third patient died from an unrelated cause.
Implications:
- Infundibulopelvic stenosis exhibits distinct radiographic features.
- The prognosis for most children with infundibulopelvic stenosis is favorable.
- Early diagnosis through imaging modalities like sonography and urography is crucial.
