ABSTRACT

Dropped renal stones pose a significant challenge in urological and interventional radiology practice. Traditional treatments include open surgery or percutaneous nephrolithotomy, both associated with potential morbidity. We present a minimally invasive technique utilizing percutaneous retroperitoneoscopy for effective stone retrieval. A 40-year-old female with persistent infection due to dropped renal stones was successfully treated using this approach. The procedure allowed direct visualization and stone retrieval with minimal tissue disruption, resulting in complete symptom resolution. This case underscores the expanding role of interventional radiology in managing complex renal conditions with innovative techniques that enhance patient recovery and outcomes.
