We investigated 80 postmenopausal women, 48 of whom (60%) agreed to undergo long-term treatment with estriol suppositories. All had symptoms of vaginal atrophy and urinary incontinence. Endometrial samples were taken after 8-10 years of therapy. Estriol had induced slight proliferative changes in the endometrium in 7 of 48 patients studied by endometrial sampling. 75% of the women reported significant subjective improvement of stress incontinence. Estriol supplementation did not produce any significant change in urethral pressure, functional length, or cystometric parameters. However, a significant increase in pressure transmission ratio to the proximal urethra was noted after vaginal medication with estriol. Replacement therapy in post-menopausal women must take into account the patients perception of risks and benefits. The risk of estriol treatment is insignificant.

A depot preparation of Estriol (Ortho Gynest D; 3.5 mg Estriol, intravaginal) was applied for 3 months to 135 postmenopausal women with urinary incontinence. Before and after treatment the symptoms of incontinence were scaled by the Gaudenz questionnaire. 8 symptoms were tested for statistical significance. All of them had significantly improved after treatment. 63% of patients showed improvement of their incontinence, urinary stress incontinence improved in 50%. Dysuria was reported by 14 patients before treatment, by none after treatment. Daytime and nighttime micturition frequency both decreased significantly, also subjective impairment by incontinence. Thus the local application of Estriol ovula represents an effective mode of primary treatment (maintenance therapy, one dose per week) in postmenopausal patients with urinary incontinence.

The finding that climacteric symptoms are caused mainly by a decline of the oestrogen level and that their development can practically always be prevented by long-term local or general oestrogen treatment was a great asset to the treatment of this problem. Oestriol, a less effective natural oestrogen, has a favourable effect on urogenital tissues without stimulating the endometrium [2]. The objective of the present investigation was to analyze ultrasonographic parameters of the lower urinary tract in women after the menopause with the stress or mixed type of urinary incontinence before and after two-month local oestriol treatment (Ovestin). The trial comprised 40 women with confirmed stress (GSI) or the mixed type of urinary incontinence. The group with GSI comprised 124 patients and the group suffering from the mixed type of incontinence comprised 26 women. The type of incontinence was assessed by urogynaecological examination. This was followed by transperineal and introital ultrasound examination of patients in a supine position by means of an Acuson 128 XP10 apparatus using a convex probe with a frequency of 5 MHz and a vaginal probe with a frequency of 7.0 MHz. Assessment of the position and mobility of the urethrovesical junction was implemented by the transperineal route using a convex probe and filling the bladder with 300 ml. After urination followed assessment of the urethral sphincter by the introital route in a vertical plane whereby the authors followed the anterior and posterior surface of the rhabdosphincter, and in a horizontal plane its left and right surface (10). The authors assessed also in both planes the maximal thickness of the sphincter. In the vertical plane and in a proximal position in relation to the urethra they evaluated the vascular supply qunatitatively (minimal-1 to very abundant-4) and also the arterial flow-the pulsatile index PI was investigated as well as the resistance index RI. In the vertical plane 1 cm from the urethrovesical junction the authors assessed the thickness of the urethral mucosa; at the same level they evaluated the thickness of the urinary bladder wall; the anterior wall, the vertex and the area of the trigone. They assessed also the thickness of pelvic floor muscles. The assessments were made before and after two-month intravaginal oestriol administration (Ovestin crm)-two weeks 0.5 mg/day and then 0.5 mg twice a week. After treatment no statistically significant differences in thickness and areas of the urethral sphincter were found nor in the thickness of the pelvic floor muscles before and after oestriol administration. Statistically significant differences were recorded in the mobility of the urethrovesical junction and there was a significant increase in the thickness of the urethral mucosa and a more abundant vascularization was recorded during the quantitative evaluation and evaluation of PI. In women with the mixed type of incontinence after oestrogen treatment a decline in the thickness of the urinary bladder was found. Ultrasound examination of the lower urinary tract before and after oestriol treatment (Ovestin crm) is a useful supplement of common examination methods and it confirms its favourable therapeutic effect when administered by the intravaginal route.

Oestriol, a naturally occurring short-acting oestrogen, was used to treat acquired urinary incontinence in 129 bitches selected by 48 veterinary practitioners in the Netherlands, Belgium, France and Germany. The dogs were treated daily for 42 days with oestriol tablets, using a self-controlled study design. The dogs were examined and blood sampled at the beginning and end of the trial. According to the veterinary practitioners 83 per cent of the dogs either became continent or improved, but the others showed no change or became worse. The owners reported similar results: 82 per cent of the dogs responded to treatment and the others did not. The dose and treatment schedule for each dog were established on the basis of clinical efficacy. Mild and transient oestrogenic effects such as swelling of the vulva and attractiveness to male dogs were observed soon after the treatment began and at the higher dose schedule used in 12 of the dogs. A haematological examination of 114 of the dogs revealed no abnormalities.

The aim of the study was to improve diagnosis and treatment of women suffering from clinical manifestations of urogenital atrophy in menopause: stress and urgent urine incontinence, disturbances of urination, recurrent infections of the lower urinary tracts. A total of 237 menopausal women were treated for urogenital atrophy for four years. The age of the patients ranged from 51 to 78 years (mean age 64.5 years). after treatment with ovestin they were followed up for 1 to 2.1 years. It was found that stress incontinence is more common in young women, older females suffer more frequently from urgent and imperative incontinence. Ovestin, as a local replacement therapy, relieved symptoms within the first several days of treatment, the complaints disappeared completely after 25 days of ovestin intake. Side effects (nausea, head ache, breast discomfort) occurred rarely, were mild and disappeared within the first two weeks of the treatment. The conclusion is made that urogenital atrophy is a common disease of postmenopausal women arising as a result of lacking estrogenization of the vagina and adjacent tissues. Urogenital atrophy manifests as stress and urgent urinary incontinence, disurea and recurrent infection of the lower urinary tracts. Ovestin therapy should be given for at least 1.5 months. In positive effect the duration of the treatment is not limited.

The aim of the present study was to investigate the pharmacokinetics of oestriol in plasma in the dog after repeated oral administration of oestriol tablets, a preparation intended for the treatment of urinary incontinence in the bitch. The study was performed in six healthy, entire, adult female beagle dogs. The bitches were treated once daily with two tablets, containing 1 mg oestriol per tablet, for seven consecutive days (days 1-7). Blood samples were taken from the jugular vein before treatment, frequently on days 1, 3 and 7 of the treatment period and daily just before (C(trough)) and 1 h after dosing (C(t=1h)). During the washout period samples were taken at a 24 h interval up to four days post-treatment. Oestriol concentrations were determined in plasma by radioimmunoassay. Pharmacokinetic parameters, AUC, C(max) and t(max), were determined from the plasma concentration-time curves using non-compartmental methods. The between animal variation in C(max) and the AUC was high. Individual values of the C(max) varied from 206 pg/ml (day 1) to 1128 pg/ml (day 7) and the AUC(0-24h) from 789 pg x h/ml (day 1) to 5718 pg x h/ml (day 7). t(max) occurred within 1 h. The mean C(trough) value was slightly above the pre-treatment level ( 38+/-2 pg/ml vs. 18+/-5 pg/ml). Within 48 h after the last treatment the concentrations had returned to the pre-treatment values. C(max) and C(trough) did not increase during the treatment period, indicating that no accumulation occurred. A shoulder in the concentration-time curve around 8-12 h after treatment strongly suggested the existence of enterohepatic recirculation (EHR). The average relative contribution of the EHR to the AUC(0-24h) was estimated to be 22%, 38% and 44% on days 1, 3 and 7, respectively. These mean values were calculated from five animals per time point, because one dog failed to show EHR on days 1 and 3 and was therefore excluded from the calculations.

Urinary incontinence as a consequence of an insufficient urethral closure mechanism (urethral sphincter mechanism incompetence, USMI) or an impaired storing capacity of the urinary bladder is a considerable side effect of castration in the female dog. Different factors such as breed, body weight and time of spaying have an impact on the risk of urinary incontinence. Loss of urine while the patient is recumbent is the most typical symptom which is first observed at a mean time of 2.8 years after castration. Diagnosis is obtained by excluding other causes, whereas a precise patient history is particularly helpful. Therapy is aimed at increasing the closing pressure of the urethra and/or the compliance of the urinary bladder. Usually success can be achieved by medical therapy, thus surgical intervention is normally not required. In addition to urinary incontinence, coat changes can be observed as an undesirable effect of castration in certain dog breeds. To date, the pathophysiology of decreased urethral closing pressure, altered storing function of the urinary bladder and coat changes induced by castration are still not fully understood. Apart from the well-known hypothesis of estrogen deficiency, altered secretion of the hypothalamic and pituitary hormones GnRH, FSH and LH due to castration may have an influence. In addition to a-adrenergic medication, Flavoxate and Estriol, depot formulations of GnRH analogues have been successfully used to treat urinary incontinence. These depot formulations have also been described for the treatment of coat changes due to spaying.
