[Position of patient-relevance to isotope nephrography in second half of pregnancy (author's transl)]. / Uber den Einfluss der Lage der Patientin bei Isotopennephrographie in der zweiten Hälfte der Schwangerschaft.

Diagnostic isotope nephrography of 63 women in the second half of pregnancy is reported in this paper. Positioning was changed for control checks, and major deviations were found to occur to the ING curve with patients in lateral position. There was, above all, an improvement in the excretion phase on the relieved side. Less variation was recorded from the secretion phase. Those findings should be taken into due consideration, particularly for diagnosis of ureter obstructions in advanced pregnancy. Lateral positioning is recommended for the above reasons also in cases of late gestosis, gestational cystopyelitis, and suspicion of intra-uterine retardation of foetal growth. Lateral positioning proved to be superior to genupectoral positioning. -- The above findings appear to provide additional evidence in support of a hypothetic proposition according to which mechanical factors are of sizeable importance to the genesis of urinary retention in advanced pregnancy. Therefore, no publication should be made without data on patient positioning.

After very good results with a new model of the Mayer-Ringpessary made of organic glass the authors used this "unbloody cerclage" as a method of choice with all patients in their district (180 000 inhabitants) with partus praematurus imminens. It is necessary controls to apply the method in stage of this complication in good-time. There were below 10% of immature children in 405 high risk patients and only 1,2% to 1500 g. They succeded to delay the delivery in more favourable time to shorten the hospitalisation and unability considerably. Perinatal mortality was also favourably influenced. The details are in tables.

[Isotope nephrography in the 2d half of pregnancy]. / Isotopennephrographie in der zweiten Hälfte der Schwangerschaft

166 Women were investigated after 26 weeks of pregnancy, divided into 4 groups (normal pregnancy, after urinary tract infection, with cystopyelitis and with toxemia). Renography is a very sensitive method. Only 6,6% women had bilateraly normal function. Unilateral pathology was detected more often on the right side (17,6% versus 2,9%) and the damage was on the right side also more intensive (30% versus 8%), and present as early as in the 7. to 8. month of pregnancy. The damage of the secretion phase of the renogram in pregnancy is mostly sequal of the disturbed drainage following compression of the ureter trough varicosal veins and the pregnant uterus.
