    Abstract:
    Urinary tract infections (UTI) are the most frequent nosocomial infections of women during puerperium. Since, in these women, diagnostic accuracy is affected by lochial secretion, suprapubic urinary bladder puncture (SPB) is recommended. Between December 1989 and January 1993, we subjected 903 women to suprapubic urinary bladder puncture (SpBP) at the 4th or 5th day after delivery. A urine culture of SpBP was done in all cases. Semiquantitative leukocyte counts (n = 891) and nitrite test (n = 830) were done on mid-stream urine (MSU). Side by side with microbiological investigation for urinary tract pathogens via SpPB, MSU was performed in 246 cases immediately after SpPB had been carried out. Leukocyte counts were also estimated in SpBP urine samples. In 370 (41.1%) of 903 SpBP, one or more microorganisms were cultivated. Only 36 (4.0%) of 903 women showed UTI symptoms. Microorganisms were detectable via SpBP in only 26 (72.7%) of these 36 symptomatic patients. Vaginal-operative or secondary caesarean section are related to an increased UTI rate (p < 0.001). UTI were also significantly (p < 0.0001) more frequent in women subjected to catheterisation sub partu (54.5%) compared to no catheterism (24.4%). No significant differences between the number of leukocytes in MSU sediment and the SpBP findings were seen. Semiquantitative leukocyte counts in SpBP offered a significantly (p < 0.001) increased number of leukocytes in cases with microorganism detection in SpBP irrespective of MSU findings. These results justify the designation of uterine tract infection also in the absence of complaints as "infection" and not common "bacteriuria".(ABSTRACT TRUNCATED AT 250 WORDS)
