Trigonal sensitivity testing, a proposed simple method for assessing bladder sensation, proved ineffective in urodynamic investigations. This technique failed to distinguish between diagnoses or correlate with key bladder function metrics in women.

Area of Science:

  • Urology
  • Urodynamics
  • Female Lower Urinary Tract Dysfunction

Background:

  • Assessing bladder sensation is crucial in urodynamic investigations but often neglected.
  • Existing electrical stimulation methods are costly, complex, and unnatural nerve stimulators.
  • Trigonal sensitivity testing was proposed as a simple, cost-effective alternative.

Purpose of the Study:

  • To evaluate a modified trigonal sensitivity testing technique in women.
  • To determine the clinical utility of trigonal sensitivity testing in diagnosing lower urinary tract dysfunction.

Main Methods:

  • A modified trigonal sensitivity testing protocol was applied to 89 women.
  • Participants included 78 women with urodynamically proven lower urinary tract dysfunction and 11 controls.

  • Sensitivity values were compared against urodynamic diagnoses and cystometric parameters.

    • Main Results:

    • Trigonal sensitivity testing did not differentiate between various urodynamic diagnoses.
    • No characteristic patterns were observed in patients with detrusor instability or bladder hypersensitivity.
    • Sensitivity values showed no correlation with first sensation to void or cystometric bladder capacity.

    Conclusions:

    • The modified trigonal sensitivity testing technique provided no clinically useful information.
    • This method is of no value in distinguishing between urodynamic diagnoses in women.
    • Trigonal sensitivity testing does not contribute to the evaluation of lower urinary tract dysfunction.
