Research summary
Urodynamic investigations are used to aid diagnosis in patients with lower urinary tract symptoms. The investigation involves measuring pressures in both the bladder and abdomen using pressure measurement catheters. These catheters are filled with a small amount of water which measures any pressure changes during bladder filling and during urination. Patient’s bladders are filled artificially through this catheter using saline.
A different type of urodynamic catheter has recently been developed which is filled with a small amount of air instead of water in order to measure pressure changes. Potential benefits of using these air-charged catheters in urodynamics include: results that are more easily interpretable, shorter appointment times, easier use, and cost savings. There is limited evidence on the comparability of these catheters to standard water filled catheters.
In this study we hope to compare water and air pressure measurements during urodynamics to provide information on whether the new air-charged catheters can be used routinely. Sixty male patients will be recruited from the urodynamic investigation waiting list and data collected during their urodynamic study in the Urology Investigations Suite, Freeman Hospital, Newcastle. Patients will be split into alternate groups where either air-charged or water filled catheters will be used. Dual pressure measurements will be made in each catheter so that in each patient we will have data on pressure measurements made using air and water, or made using water and water. This is possible by ‘re-purposing’ the channel in the catheter which is used to artificially fill the bladder. After the patient’s urodynamic investigation they will be asked to complete a comfort questionnaire about their experience. Patients will not be required to participate further.
Data collected during the urodynamic investigations will be analysed to compare pressure measurements, compare diagnoses, compare appointment lengths, and compare patient experience between the groups.
