Insights
Prune belly syndrome in identical twins suggests a genetic cause. With proper treatment, these patients can achieve normal growth and development, defying a poor prognosis.
Area of Science:
- Medical Genetics
- Developmental Biology
- Pediatric Nephrology
Background:
- Prune belly syndrome is a rare congenital disorder characterized by abdominal muscle deficiency, urinary tract abnormalities, and cryptorchidism.
- The exact etiology of prune belly syndrome remains largely unknown, with theories ranging from genetic factors to intrauterine compression.
Observation:
- This report details two cases of monozygotic twins who were both diagnosed with prune belly syndrome (PBS).
- The twins presented with concordant manifestations of the syndrome, indicating a potential shared genetic predisposition.
Findings:
- A 12-year follow-up of these twins demonstrated that appropriate medical and surgical interventions can lead to favorable outcomes.
- Patients with prune belly syndrome, despite a historically poor prognosis, achieved normal growth, developmental milestones, and preserved renal function.
Implications:
- The concordant presentation in monozygotic twins strongly supports a significant genetic component in the etiology of prune belly syndrome.
- This case series highlights the critical role of early diagnosis and comprehensive management in improving long-term outcomes for individuals with PBS.
- The findings offer hope and guide therapeutic strategies for affected families, emphasizing the potential for a good quality of life.
Abstract:
We report 2 cases of concordant prune belly syndrome occurring in monozygotic twins. In addition to suggesting a genetic basis for this disease, our 12-year follow-up of these cases illustrates that these patients with an otherwise poor prognosis can have normal growth, development, and renal function with appropriate treatment.
