Sediment in Urinary Caths

I work LTC. It seems like some residents need their caths changed every 2 weeks. Our standard is every month or prn changes.

Aside from increasing fluids..what can be done do prevent or reduce sediment. Of course we only use the caths when absolutly necessary.

Point me to some research if you can.

I have one indwelling on my unit and the urologist has us irrigating q shift and upped her to a 20 french.When she had an 18 were were changing it very frequently due to blockages. Now we only have to change it per our protocol...

I have a few individuals on my unit with caths that tend to clog with sediment. Most that start to clog get a 100cc irrigation with NSS q shift, but some get a 60cc flush of Renacidin. Even with this though, we still have some people that have to get their cath changed every 2-3 weeks.
