Area of Science:

  • Urology
  • Nephrology
  • Surgical Case Reports

Background:

  • Bladder stones (vesical calculi) can cause significant lower urinary tract symptoms.
  • Giant bladder stones are rare, with limited documented cases globally.
  • Symptomatic presentation often includes urinary retention, hematuria, and pollakisuria.

Observation:

  • A 71-year-old male presented with frequent urination (pollakisuria), gross hematuria (macrohematuria), and a sensation of urinary retention.
  • Urethrogram imaging revealed a large bladder stone alongside a smaller urethral calculus.
  • The patient underwent cystolithotomy for stone removal.

Findings:

  • A massive bladder stone weighing 310 grams was successfully excised.
  • This represents the 32nd reported case of such a large bladder stone in Japan.

Related Experiment Videos

  • Histopathological analysis of the stone can provide insights into its composition and formation.

    • Implications:

    • This case underscores the possibility of exceptionally large bladder stones forming even with modern medical advancements.
    • Surgical management, such as cystolithotomy, remains effective for removing large vesical calculi.
    • Further research into the etiology and prevention of giant bladder stones is warranted.
