Notes: Abstract Following radical hysterectomy in 42 patients with early invasive carcinoma of the cervix, ureteric strictures developed in 7 patients. They were long, smooth strictures situated in the distal ureter and thought to be of benign origin, related to devascularisation of the ureter. All but one were diagnosed within 8 weeks of surgery and all were treated by a percutaneous approach using a combination of dilating catheters and ureteric stenting: a balloon catheter was used in one patient. In 5 patients treatment was successful. In 1 patient there was an equivocal result as she developed tumour recurrence at 8 months, while in another the procedure failed, probably because the stricture was not detected for 12 months and she had also had radiotherapy. The follow-up period ranged from 6 to 26 months (mean l5 months). Although previous workers have indicated that ureleric strictures following radical hysterectomy would not be expected to respond to transluminal dilatation, in view of the devascularisation of the ureter our experience shows that the majority of these partially devascularised ureters are amenable to percutaneous techniques if detected within 2–3 months of surgery.

Description / Table of Contents: Aus dem Polymer CR-39(DOP) wurden Thermoelektrete formiert, und die thermisch stimulierten Entladungsströme wurden gemessen. Die Einflüsse unterschiedlicher Formierungstemperaturen, unterschiedlicher Feldstärken und der Lagerzeit wurden untersucht, um das Elektretverhalten dieses Materials zu beschreiben. Die Polarisation ist dipolaren Ursprungs. Die Aktivierungsenergic und die Relaxationszeit wurden berechnet.

Notes: Thermoelectrets of CR-39(DOP) were formed and their thermally stimulated discharge current studied. In the present work, effects of different forming temperatures, polarizing fields and storage times have been studies with a view to understand the electret behaviour of this material. The polarization seems to have a dipolar origin. The activation energy and relaxation times have also been calculated.
