Megacalycosis, a kidney condition, presents a higher risk of stone formation. Extracorporeal shock wave lithotripsy (ESWL) effectively treats associated urolithiasis, with yearly monitoring recommended.

Area of Science:

  • Nephrology
  • Urology

Background:

  • Megacalycosis (Puigvert's disease) is a rare renal condition with unclear pathogenesis, characterized by calyceal dilation without pelvic or ureteral obstruction.
  • Accurate differential diagnosis is crucial due to the rarity of megacalycosis.

Observation:

  • Two patients with megacalyces and associated urolithiasis were successfully treated with extracorporeal shock wave lithotripsy (ESWL).
  • Intravenous urography demonstrated high accuracy in differentiating megacalycosis from obstructive uropathy and intermittent hydronephrosis.

Findings:

  • Patients with megacalycosis exhibit an increased predisposition to developing kidney stones (urolithiasis).
  • ESWL proved effective for treating urolithiasis in the context of megacalycosis.

Implications:

Related Experiment Videos

  • The findings underscore the efficacy of ESWL for treating urolithiasis associated with megacalycosis.
  • Annual follow-up including urinalysis and intravenous urography is recommended for patients with megacalycosis.
