Matrix stones, a rare complication of kidney stones, can cause severe infection and blockage. Ureteroscopy offers an effective endoscopic treatment for removing these challenging calculi.

Area of Science:

  • Urology
  • Nephrology

Background:

  • Matrix stones are uncommon, often arising after prior treatments for complex kidney stones like staghorn calculi.
  • Previous interventions such as surgery and extracorporeal shock wave lithotripsy (ESWL) may precede matrix stone formation.

Observation:

  • A patient presented with a ureteral matrix stone causing purulent intrarenal retention, a serious complication.
  • The matrix stone developed in a patient with a history of infective staghorn calculi.

Findings:

  • Initial management involved puncture nephrostomy and antibiotics to address the purulent retention and infection.
  • The matrix stone was successfully removed using ureteroscopy, a minimally invasive endoscopic procedure.

Implications:
