Objective:Prospective analysis of the prevalence of symptoms, tolerability and complications associated with ureteral stents and their impact on quality of life based on the Flanagan Quality of Life Scale and a not-validated questionnaire from our clinic.Methods:A total of 2200 adult patient participated to this study in a period of 10 years (2003-2012). Those patients were asked to complete the QOLS and a not-validated questionnaire from our clinic, before ureteral indwelling, 7 day after ureteral indwelling and 14 days after removal of the stent.Results:Total 1520 patient aged between 18 and 84 years completed the study. The analysis of data showed that the unpleasant symptoms caused by stent were encountered more frequently at 7 days after stent insertion, in terms of urinary frequency, dysuria, urgency and macroscopic haematuria, this difference being statistically significant (p<0.05). After analysis the responses to QOLS questionnaire, at 7 days after stent placement, mean scores show a clear reduction in the QoL of those patients, in all cases the standard deviation being at a great value, indicating a high variability of responses, but at 14 days after its suppression of stent the average scores are somewhat closer to the baseline.Conclusions:Our study brings many elements that shows a statistically significant increase in the incidence of numerous side effects and impaired quality of life. It contributes to existing data from the literature as regards the knowledge of the pathology determined by the presence of foreign body in the urinary tract and in providing patient counseling.

Objectives:This study aimed at assessing the incidence of pulmonary hypertension (PH) at newly diagnosed hyperthyroid patients and at finding a simple model showing the complex functional relation between pulmonary hypertension in hyperthyroidism and the factors causing it.Methods:The 53 hyperthyroid patients (H-group) were evaluated mainly by using an echocardiographical method and compared with 35 euthyroid (E-group) and 25 healthy people (C-group). In order to identify the factors causing pulmonary hypertension the statistical method of comparing the values of arithmetical means is used. The functional relation between the two random variables (PAPs and each of the factors determining it within our research study) can be expressed by linear or non-linear function. By applying the linear regression method described by a first-degree equation the line of regression (linear model) has been determined; by applying the non-linear regression method described by a second degree equation, a parabola-type curve of regression (non-linear or polynomial model) has been determined. We made the comparison and the validation of these two models by calculating the determination coefficient (criterion 1), the comparison of residuals (criterion 2), application of AIC criterion (criterion 3) and use of F-test (criterion 4).Results:From the H-group, 47% have pulmonary hypertension completely reversible when obtaining euthyroidism. The factors causing pulmonary hypertension were identified: previously known- level of free thyroxin, pulmonary vascular resistance, cardiac output; new factors identified in this study- pretreatment period, age, systolic blood pressure. According to the four criteria and to the clinical judgment, we consider that the polynomial model (graphically parabola- type) is better than the linear one.Conclusions:The better model showing the functional relation between the pulmonary hypertension in hyperthyroidism and the factors identified in this study is given by a polynomial equation of second degree where the parabola is its graphical representation.

Overactive bladder syndrome is a chronic, disabling condition with physical, psychological and social consequences that significantly affects the quality of life of millions of patients worldwide. The economic impact of this disorder is crucial. Overactive bladder syndrome is a little-known condition, with different manifestations from patient to patient, which causes a great deal of frustration to the medical staff involved. The patient requires a clear explanation and the full support of the attending physician. It is extremely important to establish a correct diagnosis and an effective individualized treatment. The collaboration and understanding of these patients are extremely important aspects. Improving the quality of life in these patients is the main purpose in managing this condition. There are several treatment modalities that may be used progressively, with favorable albeit inconsistent results. This condition remains extremely challenging for specialists and, unfortunately, always one of maximum interest. Contents 1. Introduction 2. Risk factors 3. Pathophysiology of OAB syndrome 4.
