Exploratory Study Investigating Urodynamic Parameters During Catheterisation

Exploratory Study Investigating Urodynamic Parameters During Catheterisation

The objective of the study is to explore and understand how urodynamic parameters are affected when emptying the bladder with an intermittent catheter.

The investigation is an explorative open single arm investigation including 30 male subjects. 10 healthy volunteers, 10 patients with SCI and 10 patients with BPH.

The healthy volunteers included into the study will have an information visit and three study visits - an inclusion visit (visit 0), a visit 1 measuring endpoints while spontaneous voiding of the bladder (0-7 days after visit 0) followed by a visit 2 measuring endpoints while emptying the bladder using a standard IC (4-15 days after visit 1). (Visit 0 and visit 1 can be the same day).

The subjects with SCI and enlarged prostate will have an information visit and two study visits. - an inclusion visit (visit 0) where a urine culture is analysed and prophylactic antibiotic is prescribed per the result of the analysis. (Most IC users have bacteria in the urine and to decrease the risk of acquiring a urinary tract infection from the urodynamic examination, urine cultures are performed and prophylactic antibiotics will be prescribed per the result). The second visit (visit 1) is conducted while the patient is on antibiotic treatment measuring all endpoints while emptying the bladder with a standard IC (4-15 days after visit 0 while subject is on prophylaxis antibiotics).

The investigation is conducted at one site and is an explorative study, estimated to last eight (8) months.

Due to the explorative nature of the investigation, no primary endpoint is defined but explorative endpoints are divided into three categories dependent on their relation to bladder, urethra or urine.
