Oh now that is a question with many different sub questions isn't it?
Firstly SPC's certainly do have a purpose in a certain case. Is the patient SPCed because of BPH? Because here we don't usually do that. SPC's are reserved for usually for long term catheterisation clients.
I would be intereseted to know what you areas protocol on leg bag and night bag changes is?
Cranberry juice is an option.. only 40mls a day is needed.
Current research does point towards flushing being detrimental to the lining of a clients bladder
Obvoiusly any patient with a catheter is at risk of infection and unfortunately it is expected to be infected with a certain level of bacteria.
There are also a number of drug trials at the moment hoping to decrease the size of the prostate but no results yet. There are a number of natural health alternatives, but my patients haven't had much luck with them.... one was bovine powder??? work that one out?!?!
Also as a urology nurse we do the first change of SPC when the tract is not formed very well and can close very quickly, but after a good twelve weeks the tract is well formed.
As for internet sites I don't know.. medscape have a good urology section.
Empty the bag every 4 hours will help with ambulation status but not with the infection status as such.
There are also some companies out there that do have anti bacterial catheters - I personally haven't had much experience with them but....
Hope I have been of some help....
