The method of using sphincterotonometry during the operation, which is described in this paper, adds further importance to this means of examination besides the pre-operative classifying of urinary incontinence and the postoperative control of the surgical success. By drawing up a urethral profile and by performing simultaneous impact palpation the functional effect of the operation can be checked during the same, so that a possibly necessary correction can follow at once.--Up-til now this test has been carried out during 16 operations on urinary incontinence (diaphragma plastic by Kelly with at least one years of postoperative control).--According to our hitherto existing examinations a positive closing pressure of more than 10 mmHg is necessary for achieving a functionally satisfying operation result.
The paper refers to 126 patients on whom a plastic diaphragma operation was performed at the 1st Department of Obstet. and Gynec. of the University of Vienna. Based on the results one year after the operation, the success chances are shown and set into relation to several preexistent factors, such as severity of the incontinence, weight, parity, age and conduct of life. An increasing of the two first mentioned factors led to a significant deterioration of results. The influence of an incontinence remains incontested, yet a higher parity does not lead to significantly poorer operation results. As to the factor "age", there were no significant differences in our material. Conduct of life and additional stress in women employed in an occupation are being discussed. Furthermore it was possible to confirm the postoperative space of time needed until restoration of an undisturbed bladder function as a relatively reliable prognostic hint to the expected success of the operation. For this confirmation an objective examination method (sphincterotonometry) was used.

A report is given on the excretion of variation of-aminolaevulinic acid (ALA) as an index of the lead load in pregnant women at term and at one and also at four weeks after delivery in both mothers and the newborn infants. The mean values in women were 7.2 + 3.7 before delivery 9.0 + 4.1 one week and 4.1mg ALA/1 urine four weeks after delivery; mean values of 5.2 + 3.2 one week after birth and 2.2 + 1.0 mg ALA/1 urine four weeks after birth were recorded in the newborn infants, according to the method of Davis and Andelman. Two groups were set up: mothers coming from the rural environs of Vienna and mothers living in the centre of the city. The ALA excretion was 14% lower in the former group (20% four weeks post partum) as compared with the mothers living in the city. When these data are considered against a threshold value of 10 ALA/1 urine (set up by the "Hauptverband der Berufsgenossenschafen", Bonn, West Germany, using the same method) the mean value of 9.0mg ALA/1 urine (with individual values of up to 17.4mg ALA/1 urine) in mothers one week after delivery already seems extremely serious.
The common separation of indications at the First University Clinic for Obstetrics and Gynecology in Vienna concerning the choice of extraction instrument in cases of operative termination of vaginal delivery out of vertex position is being demonstrated. When there is only a slight increase of resistance in the delivery mechanism, when the child is mature, when there is no attitude of deflexion, and where there is no real reason for a speedy termination of delivery, the vacuum extractor comes into use. In cases of child emergency, of considerable increase of delivery mechanism resistance, of immaturity and attitude of deflexion, an extraction by means of obstetrical forceps is performed. Out of 547 deliveries terminated by means of extraction the sub- and postpartal mortality amounted to 2,19%. The number of prematures (7,5%) in this material did not differ from the total delivery material of the clinic. After forceps extraction 5 out of 419 children (2,8%) died. After vacuum extraction one child out of 105 (0,95%) died. In 23 cases where obstetrical forceps had to be used after vacuum extraction 2 children died (8,7%). The morbidity of the children was measured by means of the Apgar Score and of the injury frequency. Here the two extraction methods showed no significant differencies. The combined application of both extraction instruments however, showed an increase of morbidity. Injuries of the mother were almost exclusively found after forceps extraction.
