핵심 개념

• Struvite stone — A type of kidney stone composed of magnesium ammonium phosphate, often associated with urinary tract infections caused by urease-producing bacteria like Proteus, leading to alkaline urine and stone formation.
• Urease-producing bacteria — Bacteria such as Proteus that produce the enzyme urease, which hydrolyzes urea into ammonia and carbon dioxide, creating an alkaline environment conducive to struvite stone formation.
• Percutaneous nephrolithotomy (PCNL) — A surgical procedure used to remove large kidney stones through a small incision in the back, allowing direct access to the kidney for complete stone removal, commonly employed in struvite stone cases.
• Biofilm — A community of microorganisms embedded in a protective matrix on surfaces, such as inside struvite stones, which shields bacteria from antibiotics and complicates eradication.
• Extracorporeal shock wave lithotripsy (ESWL) — A non-invasive procedure that uses shock waves to break kidney stones into smaller fragments, but it may be insufficient alone for struvite stones due to potential residual fragments harboring bacteria.
