[The importance of ureaplasma urealyticum in non-specific prostato-urethritis (author's transl)].

312 patients with non-specific prostato-urethritis were investigated with a standardised procedure using the four glass test. In 42.3% of patients mycoplasma was isolated which in almost all cases was Ureaplasma urealyticum. Clinically patients were symptom-free after eradication of mycoplasma in cases where previously urea-plasma counts of more than 10,000 CFU/ml prostatic secretion and of more than 1000 CFU/ml urine had been demonstrated. In cases where there were smaller counts of Ureaplasma urealyticum and where Mycoplasma hominis had been demonstrated tetracycline therapy did not lead to cure in any case.
