This study found that most urethral stones in male patients, primarily composed of calcium oxalate, do not originate from the bladder and are not necessarily linked to urethral anatomical pathology.

Area of Science:

  • Urology
  • Nephrology
  • Medical Research

Background:

  • Urethral stones are a recognized urological condition.
  • The origin and characteristics of urethral stones can vary geographically and demographically.
  • Understanding these variations is crucial for effective diagnosis and treatment.

Purpose of the Study:

  • To investigate the occurrence, clinical presentation, management strategies, and outcomes of patients presenting with urethral stones.
  • To analyze the composition and location of urethral calculi.
  • To evaluate the relationship between urethral stones and underlying anatomical pathology.

Main Methods:

  • Prospective assessment of 51 consecutive male patients with urethral calculi, including one infant.
  • Detailed recording of symptoms, particularly acute urinary retention.

  • Analysis of stone composition and location (anterior vs. posterior urethra).

    • Main Results:

    • Acute urinary retention was a common presentation, affecting 78% of patients.
    • Posterior urethral calculi were prevalent, found in 88% of cases.
    • Calcium oxalate was the predominant stone composition (86%), followed by struvite (6%).
    • Urethral anatomical pathology was identified in only 6% of patients.
    • A systematic therapeutic approach was employed, correlating procedures with success rates.

    Conclusions:

    • The common assumption that urethral stones in developing countries predominantly arise from the bladder is not consistently supported by these findings.
    • Urethral anatomical pathology is not a prerequisite for the formation of most urethral calculi.
    • The study highlights the distinct characteristics of urethral stones in this patient cohort, emphasizing calcium oxalate as the primary component and posterior urethral location.
