Condition
Urological and Genital Diseases: Haemodialysis
Intervention
There will be two test groups of patients all experiencing a significant reduction in flow rate. This level will be defined as a flow rate that is less than 75% of the best flow rate achieved for that patient with the current catheter. Randomisation enrolment into Test Group 1 or 2 will be carried out by the patient enroller. Two random lists of 30 numbers have been generated. The first was assigned to brush intervention and second to urokinase intervention. The list was combined and ranked. The investigator will be provided with the blind ranked list, and assign each participant to the next sequential number. This code will be broken by an independent trialist, prior to intervention.
Added 20/07/09: the trial was stopped in 2002 due to recruitment issues.

Eligibility
Participant inclusion criteria
Patients on haemodialysis at St Helier Hospital.
Intervention groups:
1. Catheterised haemodialysis patients with a flow rate less than 75% o best flow rate. Note that the same patient may be enrolled several times into the study if flow rate is reduced below 75% several times during the course of the study.
2. Patients new to dialysis or patients that have been on dialysis for a period of time.
3. All catheter types including temporary and permanent catheters.
4. All subjects must have a clinically defined optimal flow rate.
5. All subjects must have an x-ray prior to entry into the study - this would usually be done at the time a catheter is inserted to provide information on the site, tip position and length of catheter inserted.
6. No age restriction, both sexes, no other restrictions due to other illnesses or disorders.
Control Group:
The inclusion criteria for this group are as above, but patient must have flow rates >75% of the best flow rate acheived for that patient with the current catheter. This group will be used to establish baseline complication, time and cost data.
