A broader spectrum of abnormalities in the prune belly syndrome
Insights
Prune belly syndrome causes significant health issues beyond kidney problems, including frequent pulmonary, orthopedic, and growth complications in affected children. Early infant kidney function impairment is a key indicator of later chronic renal insufficiency.
Area of Science:
- Pediatric Nephrology
- Medical Genetics
- Developmental Pediatrics
Background:
- Prune belly syndrome is a rare congenital disorder characterized by abdominal muscle deficiency, urinary tract abnormalities, and cryptorchidism.
- While renal and urinary tract issues are well-documented, the spectrum of non-renal morbidity is less understood.
- Comprehensive assessment of overall health impacts is crucial for managing affected children.
Purpose of the Study:
- To retrospectively review the clinical course of children with prune belly syndrome.
- To evaluate the spectrum and severity of both renal and extrarenal morbidity.
- To identify factors correlating with disease severity and long-term outcomes.
Main Methods:
- Retrospective chart review of 25 children diagnosed with prune belly syndrome.
- Analysis of clinical data including neonatal outcomes, renal function, growth, and associated complications.
- Correlation of renal function with growth and extrarenal problems.
Main Results:
- Three neonatal deaths occurred due to renal or pulmonary disease.
- Chronic renal insufficiency or end-stage renal disease developed in 5 survivors, often linked to early infant kidney impairment.
- Seventy-five percent of survivors experienced mild renal insufficiency.
- Growth retardation affected one-third of patients, with poor correlation to renal function.
- Pulmonary and orthopedic issues were significant in 55% of survivors; chronic constipation was also common.
Conclusions:
- Prune belly syndrome is associated with substantial renal and significant extrarenal morbidity.
- Pulmonary, orthopedic, and growth problems are common and require careful management.
- Early identification and monitoring of renal function are critical for predicting long-term outcomes.
Abstract:
The clinical course of 25 children with the prune belly syndrome was reviewed retrospectively to assess the over-all morbidity associated with this disorder. There were 3 neonatal deaths of renal or pulmonary disease. Chronic renal insufficiency or end stage renal disease developed in 5 survivors, all of whom had impaired kidney function in early infancy. An additional 17 patients survived with only mild renal insufficiency. Growth retardation, which correlated poorly with renal function, was present in a third of the patients. Clinically significant pulmonary and orthopedic problems were noted in 55 per cent of the survivors. Chronic constipation was another common, although less serious, feature. This report emphasizes the severity of the extrarenal problems associated with the prune belly syndrome.
