Summary
Brief summary
1. Background
Urethral strictures are a common cause of urinary issues for men worldwide. Repair of the urethra with a tissue graft taken from inside the cheek is currently the best treatment for long urethral strictures.

Whilst the use of an oral graft to repair urethral strictures is well studied, there has been less research into mouth problems (e.g. pain, infection) after the graft is taken.

2. Aims
This study aims to determine the rate of post-operative mouth problems in men who had an oral graft taken from inside their cheek and used to repair their urethral stricture.

This study will also investigate if certain patient's features (e.g. age, medical conditions) or operative details (e.g. size of oral graft, length of urethral stricture) are more likely to result in complications after the surgery.

3. Hypothesis
Patients who have an oral graft surgically removed are at risk of developing mouth problems.
Some patient features or operative details may increase the likelihood of complications.
