Urology/bladder stones and suprapubic catheter


I am a 60 year old male. I have suprapubic catheter since two years because my bladder has become very large and I can not empty my bladder fully. My bladder capacity reached Upto 2000l because of enlarged prostrate. After surgery the suprapubic catheter is left which I use to empty my bladder. The supra pubic catheter causes calculus formation. I am taking cran probiotics. I don't know what to do to reduce calculus formation. I do weekly bladder washouts the calculus are still forming. What diet should I take? Should I not eat diet which has oxalate? Please advise me as if the calculus form the only way I have to get them removed is by surgery. I have already removed calculi before and don't want it to firm do quickly. I have read about d manose I don't have it what do you recommend. Is vitamin c, b complex, probiotic helpful?

Many thanks,


First, we need to know what the stone is made of.  Most stones in the bladder are composed of calcium phosphate.  If so, then a daily bladder irrigation with 1/4% acetic acid or Renacidin solution should help reduce the risk of more stones.  

A 24 hour urine collection can help identify the chemical promotors of stone formation and help clarify additional preventive treatments.

Without knowing the 24 hour urine chemistry or even the stone composition, it's difficult to recommend any preventive diets or other treatments.

Smaller stones can sometimes be rinsed our, but surgery with either lasers or lithotripsy is often needed for larger stones.

There is some information about D Mannose helping with infections but not with stones.  

There is no solid information about the use of vitamin C, B complex or probiotics except in some specific situations.  You should talk to your physician or urologist about this problem.
