I have a foley in 5 days right now. Just this year for no

Customer Question

I have a foley in 5 days right now. Just this year for no obvious reason I can't urinate. I've been to the hospital 6 times for a foley. My urologist says nothing is wrong? I'm going to have it taken out today. What is my problem?

I'm Dr Chaithanya attending you today.

Why was the foley indicated? When is it blocked? after how many days of insertion?

Expert:  Dr Chaithanya replied 1 year ago.

One of the major components of catheter is encrustations with mineral salts like struvite (magnesium ammonium phosphate) and calcium phosphate, which precipitate from the urine under alkaline conditions (Cox and Hukins, 1989). Such conditions occur when the catheter surface is colonised by micro-organisms that are capable of producing the enzyme urease.

The study by Stickler et al (2003) provides the first evidence of the potential benefits of filling the catheter balloon with the antimicrobial agent, triclosan, instead of water, in order to prevent or reduce encrustation of the catheter.


You need to avoid excess dietary calcium from certain protein supplements and antacids; excess dietary magnesium from certain beverages and antacids; alkali from effervescent tablets; excess dietary citrate from some fruit juices and cordials; intermittent dehydration from alcohol ingestion.

Recurrent blockage of catheter is reduced if you follow these methods. Yes, get checked by another doctor and a second opinion is always better.
