Active clinical trials for "Urinary Bladder Diseases"

The aim of this study is to determine the fall and balance conditions of Parkinson's patients according to their urinary complaints.

A study to identify factors that are associated with improved effectiveness in pharmacologic therapy of Overactive Bladder, from the patient perspective primarily measured by OAB-Q-SF (Overactive Bladder Questionnaire Short Form)

Painful bladder syndrome (PBS)/interstitial cystitis (IC) may be due to the actions of nitric oxide (NO) in the bladder tissue. NO is a gaseous substance with a very short half-life, synthesized by a group of NO-synthase-enzymes in many tissues. The goal of this study is to illuminate bladder tissue production of NO in individuals with PBS and healthy individuals, by quantification of NO and NO-enzyme expression by different molecular biological methods.

Incidence of cancer in 75+ years old is 16,500 new cases per year, more than fifty percent of people with cancerThey are very few therapeutic trials dedicated. Oncologists hesitate to treat them because they are either afraid of inducing toxicity or of breaking down quality of life. Consequently, we decided to launch a protocol with both oncologists and geriatricians which principal aim is to find out if geriatric assessment data can help to better predict for chemotherapy toxicity, loss of autonomy and survival. We plan to accrue 360 patients diagnosed for cancer, including digestive, pulmonary, prostate, lymphoma, bladder, ovary cancer for whom first-line chemotherapy is planned. Patients are initially classified according to usual methods of medical oncology practice into three groups: patients who can receive standard treatment, reduced standard treatment or treatment adapted to the frail condition. Around Aquitaine, , we organised seven teams composed of one geriatrician and one nurse. Two kind of teams were activated: one which cover ten treatment sites in Bordeaux area and six sedentary teams which worked half a day a week in designated hospitals . Geriatric evaluation included test of cognitive functions (MMS), nutritional status (MNA), co-morbidity (CIRS-G), mobility (Get up and Go), activities (ADL;IADL), quality of life (QLQ-C30), depression (GDS-15) and Lachs-Balducci screening. Patients have four geriatric evaluations : before treatment, day 1 cycle 2, day 1 cycle 4, day 1 cycle 7 and/or end of chemotherapy. Since September 2002, 177 patients have been included, 112 have finished: 47.3% have received four evaluations, 16.1% died before the end of protocol, 14.3% stopped because they were in progression and changed their treatment, 11.6% met administrative problem that didn't allow all evaluations, 7.1% declined after inclusion and 3.6% finished their treatment before. The following results have been obtained: before treatment, 73% of these patients were at risk of undernutrition (MNA< 23.5), about 1/3 had one or more inability or a risk of falls (38% IADL<6, 29% get up and go>20seconds, 27% ADL>1, 34% PS<1), 28% of them had altered cognitive functions (MMS<24), 29% were depressive (GDS-15>6), 25% thought they had poor quality of life (QLQ-C30<4). Protocol will be closed in September 2005.

We explored the potential etiology, clinical and histopathology presentation of the eosinophilic cystitis cases, clinically mimicking urothelial neoplasia. Surgical procedure and clinical outcome also evaluated. T

Vesical Imaging-Reporting And Data System (VI-RADS) is proposed for predicting muscle invasive bladder cancer (MIBC) using multi-parametric MRI. However, No validation study on VI-RADS has been reported yet. Apparent diffusion coefficient (ADC) values on diffusion-weighted MRI are reportedly significantly lower in MIBC than those in non-MIBC(NMIBC).

The objective of the study is to obtain bladder tissue specimens from patients otherwise undergoing cystoscopy for use in research at Tengion, Inc.

Radical cystectomy is associated with a greater risk of fracture due to long-term metabolic consequences of intestinal urinary diversions. One of the mechanisms theoretically involved with bone loss after radical cystectomy is metabolic acidosis that inhibits osteoblast activity, stimulates osteoclast bone resorption and urinary calcium loss. Other factors as advanced age, diabetes or chronic renal failure may increase the effect of metabolic acidosis. Moreover, osteoporosis in men remains under-diagnosed and under-appreciated. Although metabolic and bone changes after radical cystectomy are well known, bone mineral density (BMD) or fracture risk assessment are not recommended in different international guidelines during follow-up. The objective of this study is to evaluate the fracture risk of male patients undergoing radical cystectomy after more than one year of follow-up. Fracture risk assessment will be performed by BMD to analyse the prevalence of osteoporosis, vertebral fractures and measurement of Trabecular Bone Score (TBS) in combination with the Fracture Risk Assessment Tool (FRAX). These results will be correlated with blood markers with the objective to determine independent risk factors for osteoporosis or bone fracture in this population. To the best of the investigator's knowledge this will be the first study assessing the fracture risk after radical cystectomy performance evaluating BMD and the probability of fracture at 10 years using the FRAX algorithm.

Determine differences between lithogenic and non-lithogenic bile composition.

Gall bladder status among children with chronic haemolytic anemia attending to Assuit University Children Hospital. Hemolysis is defined as the premature destruction of red blood cells (RBCs) (a shortened RBC life span). Anemia results when the rate of destruction exceeds the capacity of the marrow to produce RBCs. Normal RBC survival time is 110-120 days (half-life: 55-60 days), and thus, approximately 0.85% of the most senescent RBCs are removed and replaced each day. Patients with chronic haemolytic anemia are subjected to many complications of chronic haemolytic anemia e.g anemic heart failure, complications of blood transfusion as hepatitis and AIDS, hypersplenism, haemosiderosis ,among them there is incidence of gallbladder stone formation. This work aims to a) to determine the prevalence of gall bladder diseases among patient with chronic haemolytic anemia. b) to determine the risk factors of gall bladder diseases among patients with chronic haemolytic anemia.
