Description of intervention(s) / exposure
Urethral strictures often cause problems in men. The best way to fix urethral strictures is with mucosa from inside the cheek. The mucosa is then grafted inside the penis. This technique is called "buccal mucosa graft harvesting" and it fairly common.

However, there has been little research into complications at the buccal mucosa graft donor site. We want to find out what problems may occur inside the mouth after this operation. We also want to find out if problems are more common in some men.

This study will observe adult men who undergo buccal mucosal graft harvesting for urethroplasty. The primary aim is to explore oral quality of life in men who undergo BMG harvesting for urethroplasty at Toowoomba Hospital and St Vincent’s Private Hospital from the 1st March 2020 onwards.

Participants will be observed for 12 months post surgery. During this time, participants will complete questionnaires about pain and oral quality of life at specific timepoints. The investigators will also collect relevant demographic, medical, and operative data from the medical records of participants.

Statistical methods / analysis
It is anticipated that this study will afford a sample size of 40-60 participants. This sample size estimate was generated by considering the number of BMG harvesting procedures performed at both study sites in recent years. Since BMG harvesting for urethroplasty is a specialised genitourinary procedure, it is difficult to recruit a large number of participants for a cohort study. Indeed, only a few small studies have been published on morbidity, complications and/or oral quality of life post BMG harvesting to date.

Data will be analysed with assistance from a statistician. Descriptive statistics will be performed to illustrate trends and observations within the data. Wherever possible, inferential statistics will also be used to determine the statistical significance of differences in outcomes between patient subgroups. Statistical tests will be conducted at a p=.05 level where data permits such analysis. Tests will include, but will not be limited to, mean, median, mode, t test, chi square test, analysis of variance and logistic regression.

Summary
Brief summary
1. Background

Urethral strictures often cause problems in men. The best way to fix urethral strictures is with mucosa from inside the cheek. This mucosa is then grafted inside the penis. We want to find out what problems may occur inside the mouth after this operation. We also want to find out if problems are more common in some men.

To do this, we will collect some of your information, like age and your medical problems. We will also record any problems or pain you had after your operation. By doing this, we will better understand mouth problems that arise after taking the mucosal graft. Then in the future, doctors will be better able to inform men about how common these problems are.

2. Aims
The primary aim is to explore oral Quality of Life in men who will undergo buccal mucosal graft harvesting for urethroplasty at Toowoomba Hospital and St Vincent’s Private Hospital from 1st March 2020 onwards.

Secondarily, this study will evaluate the occurrence of post-operative complications at the buccal mucosal graft donor site.

This study will also investigate if certain demographic, medical, and operative variables are associated with post-operative complications and poorer oral quality of life.

3. Hypothesis
Post-operative complications at the buccal mucosa graft donor site result in a poorer oral quality of life.
