Megacalyosis, a rare kidney anomaly, is frequently linked to kidney stones (lithiasis) and urinary tract infections. Early diagnosis via intravenous pyelography (IVP) is crucial for effective management.

Area of Science:

  • Nephrology
  • Urology
  • Medical Genetics

Context:

  • Megacalyosis is a rare congenital anomaly affecting the renal medulla.
  • Lithiasis (kidney stones) is a common complication associated with megacalyosis.
  • Understanding the relationship between megacalyosis and lithiasis is essential for patient management.

Purpose:

  • To review a series of patients with lithiasis associated with megacalyosis.
  • To analyze the characteristics and outcomes of megacalyosis-related lithiasis.
  • To identify diagnostic methods and treatment strategies for this rare condition.

Summary:

  • This study reviewed 39 cases of megacalyosis, finding that 27 (69.2%) were associated with lithiasis.
  • Struvite and whewelite calculi were prevalent, and 40.7% of patients had urinary tract infections (UTIs) caused by E. coli, Pseudomonas, and Proteus.

  • Extracorporeal shock wave lithotripsy (ESWL) with hyperhydration was the primary treatment, and intravenous pyelography (IVP) is the main diagnostic tool.

    • Impact:

    • Highlights the high prevalence of lithiasis in megacalyosis patients.
    • Emphasizes the frequent co-occurrence of UTIs, necessitating consideration during treatment.
    • Underscores the importance of IVP in diagnosing megacalyosis.
