Suprapubic bladder aspiration is an invasive procedure in which a needle is used to obtain a urine sample directly from the bladder. Its advantages are sensitivity (detection of significant bacteriuria is close to 100%), suitability for cultivation of anaerobic bacteria, and low risk of contamination. Our purpose was to characterize the microbiology and epidemiology of urine samples obtained through this procedure in the Clinical Center of the University of Szeged’s Institute of Clinical Microbiology between 2008 and 2017.
Materials and methods
Over the 10-year period, patient data were collected and suprapubic bladder aspirations were performed, and the samples are processed in accordance with routine laboratory procedures in clinical bacteriology.
Of 187 urine samples obtained from 148 patients, 32.6% (n = 61) were culture-positive (defined as 102 colony forming units/ml or more).
This method should be considered an important sampling procedure in the differential diagnostics of upper urinary tract infections, particularly in children <2 years of age, and in older people, hospitalized patients.

Miniature silicon photodiodes have been tested for utilization in radiotherapy. Their use in the treatment of ca laryngis is described. The actually given dose was monitored during irradiation. Treatment plan or the setting up of the entrance fields was modified according to the response of the diode. This method seems to be a useful tool for checking both the treatment plan and appropriate setting up of the patient in treatment position.
