Summary

High-volume lignocaine gel (greater than 20 ml) without antiseptic improved urethral analgesia for flexible cystoscopy. Bacterial colonization was not affected by gel preparation, suggesting optimal conditions for the procedure.

Area of Science:

  • Urology
  • Pharmacology

Background:

  • Flexible cystoscopy requires effective urethral preparation for patient comfort and procedural success.
  • Lignocaine gel is commonly used for local anesthesia during cystoscopy, but optimal preparation remains debated.

Purpose of the Study:

  • To evaluate the antiseptic and analgesic effectiveness of different lignocaine gel preparations before flexible cystoscopy.
  • To determine the impact of gel volume and antiseptic presence on urethral analgesia and bacterial colonization.

Main Methods:

  • A randomized study involving 106 patients undergoing flexible cystoscopy.
  • Patients were allocated to four groups receiving different lignocaine gel preparations.
  • Assessment of urethral analgesia and bacterial colonization of the urethra.

Main Results:

  • No significant difference in bacterial colonization of the urethra was observed between the groups.
  • Improved urethral analgesia was correlated with the use of higher volumes of lignocaine gel.
  • Higher volume gel preparations (> 20 ml) without antiseptic demonstrated superior analgesic effects.

Conclusions:

  • High-volume lignocaine gel preparations (> 20 ml) without antiseptic provide optimal conditions for flexible cystoscopy.
  • Antiseptic properties did not significantly influence bacterial colonization in this study.
  • Optimizing lignocaine gel volume is key to enhancing patient comfort and analgesia during flexible cystoscopy.
