    Carbon dioxide (CO2) cystoscopy offers superior bladder visualization compared to standard water methods. This safe technique significantly improves the investigation of patients experiencing haematuria.

    Area of Science:

    • Urology
    • Medical Imaging

    Background:

    • Standard water cystoscopy is a common diagnostic procedure.
    • Limitations exist in visualization clarity during water cystoscopy, particularly in cases of haematuria.

    Purpose of the Study:

    • To compare the efficacy of carbon dioxide (CO2) insufflation versus standard water cystoscopy.
    • To evaluate the clarity of cystoscopic views and patient outcomes.

    Main Methods:

    • A prospective study involving 120 patients.
    • Comparison of cystoscopic views using CO2 insufflation and standard water methods.
    • Assessment of visual clarity and patient safety.

    Main Results:

    • Uniformly good clarity of vision was achieved with CO2 cystoscopy.

  • Significantly improved views were observed in 21 patients with haematuria compared to water cystoscopy.
  • No significant absorption of CO2 was detected, indicating safety.

    • Conclusions:

    • CO2 insufflation provides superior cystoscopic visualization, especially for haematuria investigation.
    • The technique is safe, simple, and offers considerable advantages over standard water cystoscopy.
    • CO2 cystoscopy represents a valuable advancement in urological diagnostics.
