Clinical Trial Summary

Inserting a urinary catheter in transgender men following penile reconstruction is difficult and usually requires specialist input. Specialist input may not always be readily available and clinicians may resort to suprapubic catheterisation with the associated risk of injury to the bowel or blood vessels. There is a need for an evidence-based protocol to guide clinicians faced with having to catheterise one of these patients. The investigators will evaluate how successful a specialised catheter (Urethrotech UCD®) is compared with a standard Foley catheter for catheterisation of these patients. The Urethrotech UCD® is already used for difficult catheterisation in cisgender men. Transgender men undergoing insertion of an inflatable penile prosthesis under general anaesthesia will be recruited and randomly assigned to have either the Urethrotech UCD® or Foley catheter for the first attempt at urethral catheterisation (required for standard care). If unsuccessful, flexible cystoscopy will be performed and a Foley catheter will be inserted over a guidewire. The catheter is generally removed the next day prior to discharge from hospital. Patients will be followed-up in 30 days by phone.


Description:

The only patients eligible are transgender men following penile reconstruction undergoing insertion of an inflatable penile prosthesis under general anaesthesia. Patients will be identified by the theatre booking lists at St Peter's Andrology and will be contacted by phone. The trial will be discussed and any concerns addressed. The patient information sheet will be emailed to them (or posted by mail, if preferred by the patient). Patients will be given at least 24 hours to consent to participate in the trial. As much time as possible will be given to consider the information provided. The study sites (University College London Hospital, The London Clinic and King Edward VII's Hospital) are where the operations for insertion of inflatable penile prosthesis are performed. The sites will not play any other role in the study and equipment for the study will be brought to the hospitals as required. The consent form will be signed on the morning of the procedure by the patient. Patients who consent to participate in the study will be randomly assigned to having either a Urethrotech UCD or a Bardia Aquafil Foley catheter for their first attempt at urethral catheterisation. If unsuccessful, a flexible cystoscopy (telescopic examination) will be performed and a guidewire passed directly into the bladder. A Foley catheter will then be passed over the wire, into the bladder. Following surgery, patients will be admitted overnight and the catheter removed the next day followed by discharged. After 30 days, patients will be followed-up by phone. All data will be kept in a password protected document and no data or intellectual property will be transferred to other research groups although there may be future need to share deidentified data with other groups. All study activities will be performed by the research group.

Outcome

Type Measure Description Time frame Safety issue
Primary Rate of successful catheterisation of the bladder Rate of successful catheterisation is defined by the appearance of urine from the catheter following insertion 15 minutes
Secondary Number of passes required prior to successfully catheterising the bladder Number of passes of the integrated guidewire of the urethral catheterisation device or the Bardia Aquafil catheter required in order to catheterise the bladder 15 minutes
Secondary Rate of successful catheterisation using flexible cystoscopy into the bladder Rate of successful catheterisation is defined by the appearance of urine from the catheter following insertion 30 minutes
Secondary Complication rate 30 days
