Outcomes
Primary outcome [1] 320066 0
symptomatic urinary tract infection (UTI)
- positive urine culture and
- positive lower urinary tract symptoms (weekly international prostate symptom score) and/or systemic infective symptoms assessed by research fellow .

*this is a composite primary outcome
Timepoint [1] 320066 0
first 4 weeks post robot assisted laparoscopic radical prostatectomy
- urine sample will be collected at time of trial of void and weekly for four weeks post prostatectomy unless the participant becomes symptomatic then it will be repeated according to standard of care for UTI management
- participants will be assessed for symptoms as a single assessment at time of trial of void and they will be advised to self report any signs or symptoms of UTI to treating urologist or GP in the followup period
Secondary outcome [1] 370418 0
asymptomatic bacteriuria
- positive urine culture
- without any evidence of new lower urinary tract symptoms or systemic infective symptoms - participants will be asked at trial of void about these symptoms in a study specific questionnaire and will be advised to self report any signs or symptoms of UTI to treating urologist or GP in the followup period
Timepoint [1] 370418 0
30 days following robot assisted laparoscopic radical prostatectomy

Summary
Brief summary
The purpose of this study is to determine if the use of an antibiotic (Ceftriaxone) post-radical prostatectomy will help prevent urinary tract infections in patients with a indwelling catheter inserted at time of trial of void.

You may be eligible for this study if you have prostate cancer and are undergoing a robot assisted laparoscopic radical prostatectomy at the Wesley Hospital.

Study details
Participants will be randomly allocated to one of two groups, the intervention group (standard care) or the placebo group. The procedure in the intervention group will involve:
a) Injecting 1g of antibiotic (Ceftriaxone) via an injection in the arm at time of catheter removal (one week post-surgery).
b) Collection of urine samples and blood

The placebo group will receive:
a) Injecting 10ml of saline via an injection in the arm at time of catheter removal (one week post-surgery).
b) Collection of urine samples and blood

It is hoped that this study will determine if antibiotics reduce the incidence of symptomatic urinary tract infections after catheter removal as currently they are being given to every person, which may lead to increased antibiotic resistance if they are not actually required.
