Urologic manifestations of hyperparathyroidism in childhood
Insights
Primary hyperparathyroidism affects 6% of children with kidney stones. Surgical treatment (parathyroidectomy) before stone management improved urologic complications in most young patients.
Area of Science:
- Pediatric Nephrology
- Endocrinology
- Urology
Background:
- Primary hyperparathyroidism is a rare condition in children.
- Renal stones are a common manifestation of primary hyperparathyroidism in pediatric patients.
- Urologic complications can be significant in children with this condition.
Purpose of the Study:
- To investigate the prevalence of primary hyperparathyroidism in renal stone-forming children.
- To describe the urologic manifestations of hyperparathyroidism in pediatric patients.
- To evaluate the outcomes of parathyroidectomy in managing these urologic issues.
Main Methods:
- Retrospective analysis of 9 children with surgically confirmed primary hyperparathyroidism over 24 years.
- Review of urologic complications including nephrolithiasis, nephrocalcinosis, and renal function impairment.
- Assessment of treatment outcomes following parathyroidectomy.
Main Results:
- 6% of renal stone-forming children had primary hyperparathyroidism.
- 78% of these children experienced urologic complications such as kidney stones and impaired renal function.
- All patients showed favorable responses after parathyroidectomy.
Conclusions:
- Primary hyperparathyroidism is an important, often overlooked, cause of urologic problems in children.
- Parathyroidectomy is an effective treatment for urologic manifestations of primary hyperparathyroidism in children.
- Surgical management of hyperparathyroidism should precede treatment of renal stone disease.
Abstract:
Among renal stone-forming children 6 per cent suffer from primary hyperparathyroidism. Urologic complications were noted in 7 of 9 children (78 per cent) with surgically proved hyperparathyroidism seen in a 24-year period. These included nephrolithiasis and nephrocalcinosis (6), defective urinary concentration or acidification (5) and mild impairment of renal function (3). All children responded favorably to parathyroidectomy, which should be performed before treatment of stone disease is undertaken. The nature of urologic manifestations of hyperparathyroidism and their management are discussed.
