Is screening recommended for UTI or kidney infection?

In general, screening is not recommended for urinary tract infection and kidney infection in men and nonpregnant women.

While pregnant, screening may be recommended for women because bacteria in the urine without symptoms of infection are associated with a higher rate of progression to an overt urinary tract infection and pyelonephritis. These infections can potentially compromise the fetal growth and health.

Screening for bacteria in the urine without any symptoms is also recommended for any individual prior to undergoing instrumentation of the urinary tract or in men undergoing prostate procedures. Presence of bacteria in the urine with or without an infection can possibly lead to an increased chance for developing urinary tract infection. Treating these bacteria can substantially reduce infectious complications of such procedures.

What are the signs and symptoms of kidney infection?

Some of the common symptoms of kidney infection include:

Signs of kidney infection on exam may include:

  • fever,
  • tenderness on the flanks (costo-vertebral angle tenderness, referring to tenderness upon tapping gently on the mid back on the sides), and
  • clinical evidence of infection in the urinalysis (analysis of urine).

In elderly patients and those with weak immune systems, kidney infection may be more severe with confusion, lethargy, rapid heart rate, low blood pressure, and dehydration.
