[Txe urethral pressure profile in continent and stress incontinent women (author's transl)].

The urethral pressure profiles in 21 continent and 39 stressincontinent women were recorded by the Millar-microtransducer. An analysis of the profiles of the anterior, lateral and posterior urethral wall was performed and the most significant parameters for the urodynamic diagnosis of stress-incontinence were evaluated. It could be demonstrated, that the total tonometric urethral length, the functional urethral length and the maximal urethral closure pressure at rest are of little practical value for the urodynamic diagnosis of stress-incontinence. On the other hand an excellent correlation between urethral pressure profile under stress and anamnestic and clinical stress-incontinence was found. The analysis of the pressure profiles under stress of the anterior, lateral and posterior urethral wall showed, that these have a great variability depending on the urethral sector where the measurements are performed.

[Tissue-dependent metabolic behaviour of collagen--autoradiographic and immunhistochemical findings (author's transl)].

After the intraperitoneal application of 3H-proline a higher grain density over the myocardium and the aorta in comparison with the cartilage, the glomeruli and the cutaneous connective tissue of rats was found. The maximal incorporation was established in the aorta at 6 h, in the skeletal muscle at 18 h after the injection of radioactive proline. Immunhistochemical findings reported in the literature and first results of our own indicate a special distribution pattern of the various collagen types in the organs under study. Seen in this connection the autoradiographic results may imply that type I and III collagen has a higher metabolic intensity than type II and IV collagen. Animals with renal hypertension of 3 weeks duration show an increase in the ratio of the extranuclear to the intranuclear grain density in the myocardium and the aorta after 3H-proline application.

[Studies on the duration of the DNA synthesis in the myocardium of young rats (author's transl)].

In 150 young (14-day-old) rats the duration of the DNA synthesis of myocytes and interstitial cells of the heart was investigated by double-labelling with 3H-thymidine, and by the technique of %-labelled mitoses. Both these methods showed the S-phase to last about 10 h for each of the above 2 cell types. The inhibition of muscle cell proliferation which takes place in the early stages of the postnatal heart growth does not seem to be caused primarily by a disturbance of their S-phase.

[Laparoscopic sterilization with electrocautery: complications and reliability (author's transl)].

1084 laparoscopic sterilizations were evaluated in a retrospective study at the Universitäts-Frauenklinik Zürich. The operative and early postoperative complications and the reliability of the method were analysed and compared to the results in the literature. Based on a cumulative statistical analysis 0,5% intraoperative complications required laparotomy, the main indications being haemorrhages and bowel injuries. Failed attempts were encountered in one of 150 patients, the main causes of which were adhaesions and difficulties at establishing pneumoperitoneum. The failure rate of the laparoscopic electrocoagulation of the fallopian tube after a long-term follow-up was about 0,5%, 20--25% of these were ectopic pregnancies. The transection of the fallopian tubes did not diminish the pregnancy rate, but the risk of bleeding was considerably higher with this technic. Concurrently performed therapeutic abortion or preceeeding laparotomy did not increase the operative complication rate.

[Long-term outcome of sterilization as a function of the indication, marital status, age, number of children and concurrently performed therapeutic abortions (author's transl)].

On the basis of questionnaires 1084 sterilized women were interrogated concerning their satisfaction with sterilization. 769 (70.9%) fully completed questionnaires could be evaluated. 96.4% of women were satisfied with their sterilization. 1.3% of patients requested reversal of sterilization. Non satisfactory results occured mainly in women where the indication for sterilization was on non-social basis, in single women and in cases where an interruption of pregnancy was performed at the same time. No correlation was found between age or parity and the satisfactory outcome of sterilization.

Experience with the split-thickness graft technique in congenital absence of the vagina.

Between 1961 and 1977 vaginoplasty was performed in 24 patients at the Zurich University Hospital, Department of Gynecology, using the split-thickness graft technique; in 22 cases the result was functionally satisfactory. Based on their experience and previous reports the authors describe the surgical technique and the follow-up measures designed to ensure a functionally and anatomically optimal result.

[Routine gonorrhoeae cultures: a cost--benefit analysis on obstetric--gynaecological patients (author's transl)].

Report is made on the routine check up of Neisseria Gonorrhoeae cultures of 46.081 patients. 375 (0.81%) of these showed positive results. Of the 375 positive N. Gonorrhoeae cases 122 (33%) showed neither clinical symptoms nor anamnestic indications of Gonorrhoeae. The costs for the N. Gonorrhoeae cultures amounted to sfr. 18.407.-. Distributed on the 122 non-symptomatic and anamnestically mute cases there resulted costs of sfr. 148.-for each N. Gonorrhoeae case discovered by routine check up. The setting up a routine check up of Neisseria Gonorrhoeae cultures is therefore recommended.
