Area of Science:

  • Urology
  • Medical Instrumentation
  • Oncology

Background:

  • Flexible cystoscopy is a common procedure for bladder cancer surveillance.
  • Patient discomfort is a significant factor influencing the tolerability of cystoscopy.

Purpose of the Study:

  • To compare the patient-reported discomfort of a prototype slim flexible cystoscope versus a standard flexible cystoscope.
  • To evaluate the impact of a novel cystoscope design on patient experience during bladder cancer follow-up.

Main Methods:

  • A randomized trial involving 200 men undergoing flexible cystoscopy for bladder transitional cell carcinoma.
  • Patients received intraurethral lignocaine gel anesthesia prior to the procedure.
  • Discomfort was assessed using a visual analogue scale post-procedure.

Main Results:

  • The slim flexible cystoscope was significantly less uncomfortable than the standard instrument (P < 0.001).
  • Ease of use and visualization of the bladder were comparable between the two cystoscopes.
  • No significant difference in image quality or procedural efficiency was noted.

Conclusions:

  • The slim flexible cystoscope offers a significant improvement in patient comfort.
  • This new instrument provides a viable alternative for flexible cystoscopy with comparable efficacy.
  • Enhanced patient comfort can potentially improve adherence to surveillance protocols for bladder cancer.
