Brief summary

We aim to show if introducing a delay between instillation of local anaesthetic gel into the urethra and the performance of catheterisation produces less discomfort than immediate catheterisation. The assessor who administers the pain scale rating will be blinded to the assignment of the patient (delayed or immediate catheterisation). The participant and proceduralist will not be blinded to the assignment.

Interventions

Following the instillation of standard local anaesthetic gel (lignocaine) into the urethra, participants will be catheterised immediately.
