Objective: To investigate the diagnosis and minimally invasive treatment of medullary sponge kidney stones. Methods: The clinical data and literature review of 2 patients with medullary sponge kidney stones were analyzed retrospectively. Results: 2 patients underwent percutaneous nephrolithotomy, remove most of the stones. One case of postoperative renal function returned to normal, one case of distal tubule acidosis without urinary tract infection. CONCLUSIONS: Patients with medullary sponge and kidney stones may be treated conservatively. Patients with active stones and anti-infection should be treated with percutaneous nephrolithotomy when there is obvious obstruction or infection due to stones. The short-term curative effect is satisfactory.
