Filter by:This study evaluates the continuation (non-discontinuation) of Aspirin during TURBT. Half of participants will continue their usual low-dose Aspirin regimen during TURBT and throughout the perioperative period, while the other half will discontinue Aspirin use ten days prior to surgery (standard recommendation) and restart therapy two weeks post-discharge.
Upper Urinary Tract Tumors have an incidence of 1 to 2 cases for 100 000 persons per year. The standard treatment for these tumors is the ablation of the kidney, ureter and a part of the bladder surrounding the ureteral orifice. The development of new diagnosis and treatment techniques through natural routes opens the possibility to use conservative treatments. The investigators hypothesis is that during a reno-ureteroscopy, laser confocal microscopy will allow the discrimination between normal and pathologic urothelium by microscopic analysis. This will prevent the systematic use of biopsies which are often difficult and iatrogenic.
The purpose of this study is to determine if vaginal estrogen use is associated with resolution of blood in the urine (microscopic hematuria) in postmenopausal women. The hypothesis is that postmenopausal women with blood in the urine (microscopic hematuria) will have higher rates of resolution of hematuria after treatment course with vaginal conjugated equine estrogen cream compared to placebo cream
Flexible cystoscopy has diagnostic as well as therapeutic role in many patients presenting in urology clinic with lower urinary tract symptoms (frequency, nocturia etc) and hematuria (blood in urine). Pain associated with cystoscopy varies from patient to patient, majority requires local anesthesia or lubricant solution only. During flexible cystoscopy, lubrication, use of topical anesthesia and duration of cystoscopy are recognized as important factors contributing in severity of pain of which use of intraurethral gel left to individual preference. Various studies are available reporting the pain perception with use of various intraurethral gels. Even the highest level of evidence is unable to resolve the query. With this study the investigators hypothesize that pain perception (recorded in form of pain score) during flexible cystoscopy can be reduced with use of per operative diclofenac(Non Steroidal Anti Inflammatory Drug)suppository in comparison to plain gel alone. With better control of pain the investigators aim to increase patient comfort and compliance which will increase the patient satisfaction rate and early return to work.
The goal of this study is to test whether the drug valproic acid can cause changes in bladder tumors that might inhibit their growth.
Aspirin can increase the risk of bleeding tendency. However, correlation between aspirin treatment and hematuria in general population is not well known. The investigators will evaluate whether daily use of aspirin increase the risk of microscopic hematuria in healthy large screened populations.
The study is undertaken to investigate if the urethral microtrauma, caused by intermittent catheterization, differs between three hydrophilic catheters for intermittent catheterization, LoFric; SpeediCath (SC) and SpeediCath Compact Male (SCCM). The study is a prospective, randomised, cross-over, single-centre study. Each subject will be randomized to use three different catheter types. Three catheterizations will be performed with each catheter type during one day, with at least two hours between each catheterization. The washout period between catheter switch will be at least one week. The primary objective is to evaluate urethral microtrauma for three hydrophilic catheters with regards to hematuria after intermittent catheterization. The secondary objectives are to evaluate urethral microtrauma for three hydrophilic catheters with regards to pyuria and subjective evaluation after intermittent catheterization. The safety of the three catheters will be evaluated in terms of adverse advents, non-serious and serious, rated for causality. The hypothesis that level of hematuria is equal after using different catheters will be tested using Wilcoxon signed rank test. The hypothesis will be rejected if the p-value is less than 5%.
The objective of this study is to use a DEK ELISA to quantitatively measure DEK protein in the urine of patients suspected of having bladder cancer. The measurement of urine DEK protein, relative to an established cut-off, is correlated with the presence or absence of bladder cancer.
The primary objective is to test the safety and efficacy of Velcade to induce remission in WHO class III/IV/V lupus nephritis that are refractory to standard medications.
The purpose of the study is to evaluate subjects with gross or microscopic hematuria undergoing scheduled cystoscopy to determine the absence or presence of bladder cancer.
