Candida Infections of
the Urinary Tract
Candida infections of the urinary
tract or candiduria has been well docmuneted
since 1890, when Schmorl first discovered the presence of
candida in a patient with typhoid fever. Kidney lesions have
been found in a large number of people in post mortem autopses.
However, this type of infection can present diagnostic
difficulties in individual cases.
Some hospital studies have revealed infection
rates upwards of 60% but 10% seems to be the normal infection
rate of candida in the urine. Candida albicans is the usual
infectious agent but candida glabrata has also been found in
Just because you may have candida in your urine
does not mean that you actually have a full blown
candida urinary infection. It is a generally
established rule of thumb that if the amount exceeds 10 to the
5th power ml-1 it is pathogenic. However, Haley discovered that
30% of 500 urinary samples contained yeasts but not all of
these patients had any kind of candida urinary infection. Other
scientists have said these levels are cause for alarm.
Candiduria patients do of
course tend to have higher anti-candida agglutinins in their
serum, but only 2 of 62 confirmed systemic cases of candida
caused death when candiduria was present.
Another study done on 638 patients by Kozinn,
Goldberg, and Wise found that candida concentrations of 10,000
to 15,000 yeasts ml-1 coincided with autopsy proven
Hospital catheters are the greatest risk
factor in candida urinary infections. Females have
a greater risk than males, and middle aged and older are the
most at risk. Diabetes is also an underlying risk factor as
it almost always is with chronic candida infections.
Candida Infections of
These candida urinary
infections are commonly obstructive with fungal balls
collecting in the renal pelvis. Sometimes lesions can be seen
and cancer has been present, although it has not be proven that
the candida caused the cancer.
In 1/3 of the cases fever is commonly present
at the onset of the infection and in 17% it was proven that the
patient had candida infections of other organs or candida in
the blood stream. 80% of the time the species responsible is
candida albicans but candida albicans only accounts for rougly
55% of the yeasts found in urine without the kidney
Babies with renal candidia are usually the
result of premature birth and complications in the urinary
tract, and mortality rates run as high as 31% in these neonatal
Most renal candida infections are a result of
candida being found in the bloodstream and the candida infects
the host as the blood passes through the kidneys to be cleaned.
If not diagnosed early enough so it can be treated with azole
drugs, the candida usually shuts down the kidneys causing
Candida can also infect the bladder although it is somewhat rare.
Lower urinary tract infections are more frequent and the
common symptoms are itching and a scanty discharge. It is
much more frequent in women than men because of the obvious
differences in sexual organs and prevelance of vaginal yeast
Prostatitis can also be caused by candida and
can reduce sperm motility and cause agglutination of the
spermatozoa, which suggests it can cause sterility. Sex with a
woman that has a vaginal yeast infection and catheters are a
risk factor for these infections. However, prostate glands infected by yeast is
Treatment Options for
Candiduria and Urinary Candida Infections
Usually systemic chemotherapy with antifungal drugs and in some cases
surgery is the most successful treatment for these types of
infections. The single most effective drug seems to be
flucytosine with a better than 90% success rate although you
run the risk of the candida building resistance to the drug.
Another azole drug that looks promising is fluconazole since it
is secreted in the urine like flucytosine. The best method
would probably be a rotation of the two drugs at sufficient
doses, to little is worse than not enough. No treatment at all
resulted in an 87% death rate.
Natural treatments would consist of
Candidate, CandidaClear, Coconut Oil, GSE and Organic Oregano
Oil in very high doses. However, it might be
best to see a qualified doctor and use the azole drugs for
candiduria and candida urinary infections since
it is so life threatening.
