Study type
Description of intervention(s) / exposure
This is an extenson of a previous study registration number:
ACTRN12610000637044. The previous study was titled "A comparative study between the use of the conventional silicone catheter and the surgical stainless steel catheter". The previous study only enrolled 10 participants to trial the catheter. The participants who were involved in the study reported that the surgical stainless steel catheter improved bladder emtpying, reduced time to void, did not need lubrication and it was easier to carry around.

This present study has been designed to further evaluate incidence of infection, ease of use and continence specific quality of life in 50 female pateints comparing a conventional silicone catheter with a surgical stainless steel catheter. Patients wil be asked to catheterise for 3 months using the silicone catheter followed by 3 months with the stainless steel catheter, catheterising at their usual frequency ie 3-4 times per day

Brief summary
This study has been designed is to compare the incidence of urinary tract infections (UTI) in 50 female patients who need to self catheterise to properly empty their bladders.
Participants in this study will be monitored for a 3 month period for frequency of UTIs, ease of use and continence specific quality of life while using the Nelaton silicone catheter, followed by a 3 month study period using a surgical stainless steel catheter assessing the same parameters for intermittent self catheterising.
During the 6 month study peroid, participants will be asked to keep a urinary diary and they will be monitored closely for urinary tract infection (UTI). If a participant develops symptoms of UTI, a urine sample will be obtained and sent for urinalysis. If positive they will be commenced on appriopriate antibiotics and a decision will be made whether the patient needs to be withdrawn from the study.
At the end of the study, each participant will be asked to complete a patient satisfaction survery and continence specific quality of life questionnaire.
