Urodynamic evaluation of urinary incontinence using a microtransducer.

Using the Millar Microtransducer system urodynamic measurements were made before and 1 year after 100 operations for urinary stress incontinence. Seventy-eight of the 100 patients were completely continent 1 year after surgery. The results were compared to the findings in 44 normal women. The urodynamic data obtained little relation to the clinical findings because of a large scatter around the mean value. There were significant differences between pre- and postoperative values and normal examinations. However, in continent patients the postoperative values were still not in the normal range, and some values increased in some patients and decreased in others. The lack of consistency may have been due to the Millar Microtransducer which is not specially designed for the measurement of urethral pressure profiles.

[Breech presentation (author's transl)].

The perinatal mortality and morbidity of 303 breech deliveries was investigated. In 80 newborn the acidosis (pH less than 7.20) was due to positional variations such as footling, knee and mixed breech presentations in vaginal deliveries. Our results are incorporated in a new concept of triage which permits continuing vaginal breech deliveries as a calculable risk.

[Normal reference values in frequently carried out laboratory analyses hematologic cytology and blood coagulation)].

In 310 individuals (165 men and 145 women) significant pathological processes were exluded by reference to the patient's history, by physical investigation and by detailed laboratory tests (clinical chemistry, hematological cytology and most important coagulation analyses). Hematological laboratory values were then evaluated for age and sex differences, and in women according to menstruation versus post-menopause an oral contraception. Only the well known sex-specific differences in hematocrit values, hemoglobin and red cell counts were statistically highly significant (Z > 10). All other hematological values were pooled after exclusion of methodological errors. According to the non-symmetrical distribution of hematological laboratory values, percentiles were calculated. The 2.5 to 97.5 percentiles thus established now serve as "normal hematological reference values" for our laboratory.
