, In January 2013 I broke my neck at C4/5 in an accident. The spinal cord injury has left me with double incontinence. In May 2013 I had a suprapubic catheter installed.
Between January and July 2016 I had 23 catheter blockages. I began to have weekly bladder wash-outs in March 2016. I have never had a blockage during the day or night following a wash-out but they continued at other times.
The contents of my catheter at the time of blockage were never tested but after a while it began to look as though some, perhaps most of my blockages were associated with urinary tract infections: so if my infections could be stopped, so too would the blockages.
I started using Nitrofurantoin to prevent rather than to cure infections immediately after my last blockage on 24th July 2016. I have had no blockage since. I took 50mg each evening for 30 days; then I gradually reduced it, and from the beginning of 2017, partially replaced it with natural antibiotics.
As far as I am aware, neither have I had a urinary infection since July 2016; certainly not one sufficiently clear to be recognisable without bacterial analysis or to create enough sediment to cause a catheter blockage.
Of course, this is only my own story. I do not know for how many other people the methods would be suitable.
