Hi All..I wanted to ask if anyone else gets UTi symptoms but more often than not a sample is clear of bugs..or they cant define a bug exactly? I have had UTi symptons during the day since my retention of urins started in 1988. I have had three nasty kidney/bladder infections, the last bein in 2007(allot of blood in urine that time for a week). have been on nitroforantoin 100mg at night but nothing to cover me for the day. I self catheteraise through a stoma near my belly button as ISc became impossible through the normal route by 2002. The irritation is uncomfortable and often feel I need to empty more often. Have had these again in last- 3 days so will pop a sample down to gps today for them to dipstick. Does anyone have these problems also? Any advice? I dont realy understand why I have so much discomfort and yet the sample is often clear..
