    ABSTRACT: Nocturia is the complaint that the individual has to wake at night one or more times to void, according to the International Continence Society definition from the ICS Standardisation of Terminology Report 2002. As the nocturia definition is complicated there are also other slightly modified definitions. It is currently not absolutely clear if prevalence or incidence is more important for epidemiology evaluation of nocturia. Nocturia is a variable symptom and its presence in individuals is reversible therefore it is very difficult to obtain reliable incidence data. Nocturia prevalence varies remarkably in different studies according to evaluation methodology, nocturia definition, methods of data collection and characteristics of evaluated population. There are not enough studies, especially demographic ones, evaluating lower urinary tract symptoms and/or nocturia in males and females. There is relatively large number of comparative studies confirming strong correlation between aging and prevalence of nocturia. Prevalence of two or more voids per night in individuals in their twenties varies between 5-15 %, it progresses with age, and in the seventh decade of life ranges between 35-50 %. Prevalence evaluated by gender is higher among younger women compared to older women and older men compared to younger men. Currently there are only limited sources of data regarding nocturia incidence. Incidence of nocturia (two or more voids per night) in a population older than60 years is 213 new cases/1000 persons/1 year in two year observation. Incidence of two or more voids per night is 75 new cases/1000 male/1 year in five year observation and 126 new cases/1000 male/1year in ten year observation in male population. Incidence of nocturia rises significantly with age. Incidence of two or more voids per night increases by 2,7 % in the population of women after child birth during 5 year follow up and by 5,9 % during 12 year follow up. Incidence of nocturia newly diagnosed in a pregnancy drops down by 98% in 3 month after the child birth. The incidence data indicate that incidence of nocturia rises with age and probability of nocturia relief decreases with age. Incidence of mild nocturia is higher compared to incidence of severe nocturia and significant relief of nocturia in women after child birth is very inconsistent compared to increase of other lower urinary tract symptoms. Ethiology of nocturia might be polyuria, nocturnal polyuria or reduced bladder capacity. Nocturia and its ethiology can be determined in most cases with simple and commonly used investigative methods on the out-patients bases. The diagnostic algorithm should lead to verification of nocturia and identifying its cause because treatment of nocturia differs remarkably according to the etiology.. Keywords: nocturia - prevalence - incidence - ethiology - diagnostics.

    ABSTRACT: Unlabelled: Nonpharmacologic and especially pharmacologic treatment options are available for nocturnal polyuria. Desmopressin represents the basis of pharmacologic treatment. Desmopressin acetate is a synthetic analogue of arginine vasopressin with high affinity to V2 receptors with antidiuretic effect. It is the only medicament currently registered for antidiuretic treatment. Desmopressin has not any relevant affinity to V1 receptors, and therefore there is no hypertensive effect in contrary to natural vasopressin. Desmopressin use before a bedtime leads to reduced production of urine during a sleep, therefore time between desires to void is prolonged and number of nocturia is reduced. Clinical effect, in a meaning of reduced urine production and increased osmolality of urine, lasts approximately 8-12 hours. In the treatment of nocturnal polyuria desmopressin is used orally one hour before a bedtime. It is essential to titrate an ideal dose, the initial dose is 60 µg of MELT formula (fast melting oral formulation) and it can be increased according to the clinical effect up to the maximal recommended daily dose 240 µg. Patients treated with desmopressin should cut down a fluid intake 1 hour before and 8 hours after the use of desmopressin. Total number of adverse events connected withdesmopressin treatment in clinical studies was higher compared to placebo but the side effects were mostly mild. The most common adverse events were headaches, nausea, diarrhoea, abdominal pain, dry mouth and hyponatremia both in the short-term and long-term clinical trials. Hyponatremia was observed mainly in patients over 65 year of age. Therefore treatment with desmopressin should not be commended in patients over 65 year of age without close monitoring of the natrium level in serum and all patients should be informed about the first symptoms of hyponatremia - headache, nausea and insomnia. According to Evidence Based Medicine, the level of evidence for treatment of nocturnal polyuria with desmopressin is 1b and the grade of recommendation for treatment is A. Keywords: nocturnal polyuria - treatment - desmopressin.

    ABSTRACT: Breast cancer characteristics obtained at the time of diagnosis are important for setting the basic strategy of the treatment. Reliability of preoperative investigation differs for various features of the disease. The aim of this study was to ascertain the agreements and differences between preoperative and postoperative values. This retrospective study analyzed the results of 617 women with primary surgery of the breast and axilla. Cohen's kappa coefficient has been employed to measure the degree of agreement between preoperative and postoperative values. Substantial or "almost perfect" agreement has been documented for the histological type of the tumors, their histopathological grade, proliferation index Ki67, as well as for estrogen, progesterone, and HER-2/neu receptors. Substantial differences exist between preoperative and postoperative diagnoses of invasiveness of the tumor, determination of the size of the tumors, and the number of tumor foci. Preoperative imaging and clinical examination of lymph nodes exhibited unacceptably high false negative rates. Heterogeneity of breast cancer cell population, methodology of histology examinations, and insufficient imaging of lymph nodes are the major limitations precluding satisfactory accuracy of preoperative diagnosis. Preoperatively diagnosed in situ carcinomas, as well as multifocal lesions, were the most often sources of diagnostic failures.

    ABSTRACT: The aim of this study is to determine the combination of characteristics in early breast cancer that could estimate the risk of occurrence of metastatic cells in axillary sentinel lymph node(s). If we were able to reliably predict the presence or absence of axillary sentinel involvement, we could spare a considerable proportion of patients from axillary surgery without compromising therapeutic outcomes of their disease. The study is based on retrospective analysis of medical records of 170 patients diagnosed with primary breast cancer. These women underwent primary surgery of the breast and axilla in which at least one sentinel lymph node was obtained. Logistic regression has been employed to construct a model predicting axillary sentinel lymph node involvement using preoperative and postoperative tumor characteristics. Postoperative model uses tumor features obtained from definitive histology samples. Its predictive capability expressed by receiver operating characteristic curve is good, area under curve (AUC) equals to 0.78. The comparison between preoperative and postoperative results showed the only significant differences in values of histopathological grading; we have considered grading not reliably stated before surgery. In preoperative model only the characteristics available and reliably stated at the time of diagnoses were used. The predictive capability of this model is only fair when using the data available at the time of diagnosis (AUC = 0.66). We conclude, that predictive models based on postoperative values enable to reliably estimate the likelihood of occurrence of axillary sentinel node(s) metastases. This can be used in clinical practice in case surgical procedure is divided into two steps, breast surgery first and axillary surgery thereafter. Even if preoperative values were not significantly different from postoperative ones (except for grading), the preoperative model predictive capability is lower compared to postoperative values. The reason for this worse prediction was identified in imperfect preoperative diagnostic. Keywords: breast cancer, tumor characteristics, sentinel node metastasis, preoperative diagnosis, postoperative diagnosis, predictive model.

    ABSTRACT: Objective: Comparison of different types of tension free tapes in the treatment of urinary incontinence in institutionalized elderly patients.Design: Prospective randomized study.Setting: Charles University in Prague, 1st Medical Faculty and Hospital Bulovka, Department of Obstetrics and Gynaecology, Prague.Methods: 43 patients of several gerontologic centres with prevailing stress urinary incontinence were included based on urinary dysfunction specific questionnaire (ICIQ) and cognitive functions objective estimation (MMSE). Three types of tapes, TVT-O, MiniArc and Ajust were used and patients were randomized into the groups and after an urogynaecologic examination, incl. ultrasound the operation was performed.Results: The groups were - except of the age of the patients of group MiniArc - well outweighted concerning demographic parameters. High success rate of all techniques used evaluated by the QoL questionnaires was in all the groups comparable. No case of bleeding, bladder injury or postoperative pain was found. Higher frequency of OAB de novo and worsening of preexisting symptomatics could be explained by general very high prevalence of OAB in the elderly even without the operation. In whole our cohort only 1 case of failure to treat and of tape exposure was found. Our results confirming high success rate of all the types also in elderly and institutionalized patients are in consent with sporadic published data. Conclusion: Surgical treatment of cases of stress and mixed urinary incontinence is also in cases of elderly polymorbid nurcing facilities clients with regard to the high success rate. Secondary outcome of our report when accepting the conclusion is drop of the costs of antiincontinence pads thus having a significant economic effect. Key words: urinary incontinence, geriatric patient, suburethral vaginal tape.

    ABSTRACT: The objective of the study was to compare recurrence and complication rates for sacrospinous fixation (SSF) and prolene mesh techniques for the primary treatment of posthysterectomy vaginal vault prolapse. Patients undergoing surgery for vault prolapse were included in a multicenter, randomized, controlled study comparing SSF or total mesh (Prolift; Gynecare/Ethicon, Somerville, NJ). The examination included pelvic organ prolapse quantification, urodynamics, ultrasound, and quality-of-life (QoL) questionnaires before and 3 and 12 months after surgery. Of 168 randomized patients, 83 underwent SSF and 85 mesh repair. Prolapse recurrence after 12 months occurred in 39.4% of the SSF group and in 16.9% of the mesh group (P = .003). The mesh exposure rate was 20.8%. No difference in QoL improvement as well as of de novo stress urinary incontinence and overactive bladder onset was found. Mesh exposure occurrence was balanced against a lower prolapse recurrence rate in the patients undergoing mesh surgery compared with those undergoing SSF.

    ABSTRACT: Sentinel lymph node biopsy (SLNB) is a widely used staging method for patients with early breast cancer. Neoadjuvant chemotherapy modifies the anatomical conditions in the breast and axilla, and thus SLNB remains controversial in patients treated preoperatively. The aim of this study was to demonstrate the reliability and accuracy of this procedure in this particular group of patients. The retrospective study analyzed medical records of patients diagnosed with primary breast cancer between the years 2005 and 2009. Of the patients treated by neoadjuvant therapy, 343 underwent lymphatic mapping to identify sentinel lymph nodes, and these were included in the analysis. The overall detection rate of sentinel lymph nodes was 80.8%. It was strongly influenced by clinical lymph node status (significantly higher success rate in lymph node-negative patients); higher detection rates were also associated with age <50 years, estrogen receptor positivity, lower proliferation index, and absent lymphovascular space invasion. The false-negative rate was 19.5% and was only marginally significantly dependent on lymphovascular space invasion. The overall accuracy of the method was 91.5%. By using the present technique, sentinel lymph node biopsy cannot be recommended as a reliable predictor of axillary lymph node status when performed at the authors' institution after neoadjuvant chemotherapy. Infrequent use of blue dye for lymphatic mapping, low number of resected sentinel lymph nodes, and absence of any selection among patients included in the study could be the main factors responsible for the low detection rate and high false-negative rate.

    ABSTRACT: In the majority of recent textbooks of obstetrics, a routine follow-up examination at the end of the postpartum period is recommended. To date, no studies have been done in the Czech Republic addressing use of contraception and follow-up care in the postpartum period. Questionnaires were sent to 672 participants who gave birth in the year 2008, inquiring about follow-up examinations in the postpartum period and use of contraception. In total, 458 (68.2%) questionnaires were returned. 430 women (93.9%) underwent routine examinations at 6 weeks into the postpartum period. At the time of examination, 36 women were asked about their particular health problems (8.4%). In 130 instances, the question most often addressed by the outpatient gynecologist concerned use of contraception (30.2%). However, only 34 physicians expressed concern about changes in sexual life or other sexually related problems. 426 women (93.0%) were sexually active and 310 women (72.8%) did not use any contraception with the exception of breastfeeding. The current practice of outpatient gynecological visits at 6 weeks postpartum and advice on contraception both seem inadequate.

    ABSTRACT: HELLP syndrome is a serious obstetrical complication that tends to occur in the second half of pregnancy that complicates six promiles of pregnancies. The term HELLP syndrome is derived from the beginning letters of the English words indicating laboratory changes, which is occurs as a specific illness in pregnancy. There is hemolysis, elevated liver enzymes and a decreased platelet count. It can present itself with preeclampsia or without it. The most serious complications are disseminated intravascular coagulation, liver rupture or various organ failures. The pathogenesis at the moment is not completely known. The basic approach to care is delivery at the earliest possible term. HELLP syndrome generally arises in the second or third trimester of pregnancy, but can also occur after delivery. It has typical signs, which can also arise due to other liver diseases, but more frequently in diseases of the gall bladder, which in pregnancy given the physiological changes in the body of the pregnant women is also predisposed. In this context, woman with this problem can seek out other physicians than obstetricians. In our case, we wanted to refer to the needs of early diagnosis of this frequently diagnosed illness, since in the case of late diagnosis and a woman not sent to the obstetrical department can lead to a serious life threatening state for the mother and child.

    ABSTRACT: The set of pregnant females suffering from bronchial asthma-retrospective analysis. Type of study: Retrospective analysis. Department of Obstetrics and Gynecology, University Hospital Na Bulovce, First Medical Faculty, Charles University in Prague, Czech Republic. Our set consists of pregnant women suffering from bronchial asthma and attending our Antenatal Clinic & delivering at our Maternity Hospital from January 2008 through December 2009. Retrospective analysis of the set based on the medical records was performed. 80 females suffering from bronchial asthma gave birth at our Hospital during the studied time span, i.e., 1.7% of all deliveries at our Maternity Hospital. In 4 females (i.e. 5%) the asthma attack was observed during the pregnancy. 33% of all females suffering from bronchial asthma did not require any bronchodilator medication, 22% were just on betamimetics, 23% required inhalational betamimetics with intermittent inhalational corticosteroid and 21% use both regularly. Perorally corticosteroids or leukotrien inhibitors were not used at all. There was no negative influence on subjective felling of the female during her pregnancy and labor in 71% of cases. 24% of all females suffering from bronchial asthma delivered by Caesarean Section but just in two of them it was indicated due to the bronchial asthma itself. We observed no case of IUGR or congenital defect. No change in the length of the hospital stay in comparison to the other females was shown. The nowadays standard treatment of bronchial asthma during pregnancy is based on local inhalative bronchodilator and anti-inflammatory medication. Pregnant females are usually well compensated, and thus their perinatal outcome shows no difference compared to the healthy population.

    ABSTRACT: To assess the classification, repair, and follow up of extensive obstetric perineal injuries in the Czech and Slovak Republics. A survey conducted in 2009 using questionnaires distributed to obstetric departments regarding classification and management of obstetric perineal injuries. Although 15 centers in the Czech Republic and 2 in the Slovak Republic indicated use of a 4-degree classification system, none of these centers reported using the classification accepted by the Royal College of Obstetricians and Gynaecologists. Use of a 3-degree classification system in accordance with definitions in Czech textbooks was reported by 14 Czech and 3 Slovak maternity hospitals. There was significant heterogeneity in clinical practice regarding techniques to repair extensive obstetric perineal injuries, antibiotic prophylaxis, early postpartum care, and follow up. There is great inconsistency in the classification and management of extensive obstetric perineal injuries. Uniform recommendations should be created and accepted, not only in the Czech and Slovak Republics, but worldwide.

    ABSTRACT: Analysis of two cases uterine rupture following caesarian section. Two case studies. Gynecological obstetrics clinic, First Medical Faculty and Faculty Hospital Bulovka, Prague. The authors in their article describe two cases of rupture of the uterus in pregnancy prior to delivery. In both cases there was a history of cervicocorporal caesarian section. In the first case the patient was admitted from her home with bleeding, and signed a nonconsent form. The second case concerned a hospitalized patient, in which the first signs of uterine rupture were indicated by fetal heart rate. Both women underwent hysterectomy, paradoxically, in the first case the child was saved and discharged home in good health.

    ABSTRACT: Retrospective analysis of the population of women examined for suspicion of sexual assault to compare the situation in the Czech Republic with the world's published works. Retrospective analysis. Department of Obstetrics and Gynecology, 1st Medical Faculty of Charles University and the Faculty Hospital Na Bulovce Prague. Retrospective analysis of medical reports for all women examined for suspicion of sexual violence during the period from January 2007 to December 2008. During observed period 37 women were examined, average age of examined women was 26.2 years, range 15-51 years, 76% of females younger than 29 years, 16% of examined women were from abroad. We have found no differences in occurrence throughout the year. In 3 cases there were more aggressors, in 30% of cases the alleged perpetrator was a known person or relative. In 54% of cases completed vaginal intercourse with ejaculation allegedly took place. We detected one case of forced oral sex and one case of forced anal sex. In 19% touching was involved. 22% of women did not know whether coitus really occurred--in 14% the alleged victim was under the influence of alcohol, in 3 cases under the influence of drugs, including one case of drinking an unknown substance in a beverage. Obvious signs of violence were found in 27% of cases, of which mostly in the face (14%), the extremities (8%) and only in two cases on the genitals (5%). No woman did require medical treatment of injuries. Our experience is similar to the published world data. In our group there were more strangers among the perpetrators. We did not record any use of a weapon in the enforcement of sexual contact. It is necessary to examine the alleged victims whole body thoroughly, signs of violence were more frequent in extragenital localization.

    ABSTRACT: Polypropylene mesh in the treatment of genital prolapse in women was introduced at the turn of the millennium with the rationale of decreasing surgical invasiveness, reinforcing weak tissues and to possibly complement insufficient surgical techniques. Prospective randomized studies comparing traditional and modern operations are lacking. Prospective multicentre randomized study. Department of Obstetrics and Gynaecology, The First Faculty of Medicine, Charles University in Prague. A prospective multicentre trial was approved by the Ministry of Health of the Czech Republic and registered with the FDA planning to recruit 500 patients with vaginal prolapse, 18 years of age and over, undergoing surgery at 5 major urogynaecologic centres. The patients were divided into three groups according to prolapse predominance. The surgical techniques used were: anterior and posterior prolift, and randomly allocated total prolift or sacrospinous fixation. The examination setup included lower urinary tract ultrasound, MRI, POP-Q assessment and QoL questionnaires before surgery and six and 24 month after the surgery. Preliminary analysis of partial data of 225 women showed an acceptable rate of complications and a better success rate in the mesh groups, whereas operation time and blood loss was lower in the classical operation group. Quality of life questionnaires documented that all the methods used have comparably good results. The surgical techniques used are acceptable methods for pelvic organ prolapse repair with low complication rates and excellent impact on the subjective perception of the patient's quality of life.

    ABSTRACT: The aim of this paper is to introduce the new Single-Incision Sling System MiniArc in treatment of the female stress urinary incontinence. Prospective follow up. Department of Obstetrics and Gynaecology, The First Faculty of Medicine, Charles University in Prague. Prospective follow up of the first set of 38 patients treated with the new method MiniArc. We performed initial 38 cases of MiniArc under the local anesthesia. There was neither the complication during procedure, nor during the early postoperative period. No patient required urine derivation. Late postoperative period showed neither obstruction, nor ,,de novo urgency". One asymptomatic sub-urethral tape protrusion into the vagina was found. No late postoperative pain occurred. Subjective cure rate was investigated in 33 ladies with follow up from 6 weeks through 19 months. 23 females declared full dryness (i.e., 76.7%), 6 patients were very satisfied and declared improvement of more than 70% (i. e. 20.0%); thus we obtained efficacy in 29 cases of 30 (i. e. 96.7%). We have not seen any vanishing of the sling effect. Based on our initial experience we judge the new single incision tape as very promising.
