Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Before and after the resection of the prostate, the bladder will be filled with fluid as per the standard technique for TURP I.e a rigid cystoscope inserted into the bladder via the urethra and irrigation glycine fluid will fill the bladder to a set measurement of 500ml. The scope will then be removed and pressure applied to the abdomen by the surgeons hand to expel the fluid. The pressure is up to the discretion of the single operator. The voided fluid will then be graded on its flow by the surgeon and study assessor to get a unanimously agreed upon score on the standardised scale.

Outcomes
Primary outcome [1] 307984 0
As this is a feasibility/pilot study the main aim is to see if the method is functional. Determining if the method of flow measurement is feasible I.e can be done and measured, in the context of the study. 1. Checking reproducibility by grading the flow twice to see if consistent.
2. Two assessors of flow to agree on outcome according to flow score
3. Feedback from assessors on the practicality and efficiency of measurement within time constraints and operating constraints of the procedure. Regular meetings will occur to discuss progress and the protocol in case any changes need to be made for practical reasons. No formal questionnaire is being done.
Timepoint [1] 307984 0
At the time of operation and feedback after each procedure within the recruitment period over 6 months
Secondary outcome [1] 353563 0
Specific complication rates e.g. recurrent urinary retention, significant bleeding, further objective uroflowometry, ongoing incontinence, need for alternative management with suprapubic catheter or intermittent self catheterisation. This will be identified by going through medical records and the surgical audit programme prior to follow up. Also these things will be assessed at the follow up appointment in a clinic setting with a history, exam and flowometry at the time.
Timepoint [1] 353563 0
Over 6 weeks follow up
Secondary outcome [2] 353564 0
Patient satisfaction scores according to the International prostate symptoms score IPSS survey
Timepoint [2] 353564 0
