I am a 49 year old male with M.S which i have had for 27 years. For the last six years i have used a Supra Pubic Catheter. Although in the past i have had problems with bladder stones a recent x-ray shows this is not the cause. My problem is i am leaking from the catheter entrance and also the penis, which is causing me discomfort and embarrassment as the urine has a very strong odour. I have noticed that the tube to the leg bag appears to accumulate what looks like fungi - although a wash out shows the catheter is not blocked this leakage still occurs. Can you please offer me some advice?
