Persistent renal dysfunction post-chemotherapy: a diagnostic conundrum in pediatric cancer survivorship – a case report

This case highlights the importance of considering late-onset Bartter syndrome in patients with a history of chemotherapy presenting with persistent electrolyte imbalances and ongoing renal dysfunction. The atypical features and rapid progression of chronic kidney disease in this patient may be attributed to the deleterious nature of the identified variants and the potential impact of previous chemotherapy on kidney susceptibility to damage. Careful monitoring and management of electrolyte imbalances and renal function are crucial in such cases.
