I already had a stricture before my Salvage RT. I had a suprapubic catheter fitted before my SRT as insurance against the SRT causing my stricture to get worse.
Four months after completion of my SRT, I started passing lots of blood clots and debris and the bladder capacity was drastically reduced. I didn't notice any change in frequency because I had the catheter. It is quite rare to get my level of damage from SRT.
If you do start passing lots ot blood clots etc get help from someone who understands radiation cystitis.By the time my problem was diagnosed the bladder was beyond help. As already said, if you do start getting retention, get to A&E without delay, it is classed as a medical emergency.
