Women arriving to the Urology department outpatient clinic at Assaf-Harofeh Medical Center in order to undergo a cystoscopy examination will be recruited. Patients will be randomly assigned to one of four groups by method of cystoscopy (flexible and rigid) and by use of anesthesia to the introitus. Pain levels will be recorded prior to the examination, during entrance of the cystoscope in the urethral meatus, immediately after the examination and 15 minutes after conclusion.
The purpose of the study is to investigate sexual function in patients suspected of non muscle invasive bladder cancer (NMIBC). The investigators hypothesis is that reduced sexual function is underdiagnosed in patients with non-muscle invasive bladder cancer and that active examination and treatment may worsen the sexual function.
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.
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 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.
To assess the influence of seasonal variations in Schistosoma haematobium transmission on treatment outcome (morbidity and re-infection)
The study will help define the best tolerated approach to cystoscopy in women by randomly comparing flexible to rigid cystoscopy. Previous randomized studies evaluated rigid cystoscopy under general anesthesia versus flexible cystoscopy under local anesthesia. As a result of these studies, flexible cystoscopy is performed in the clinic setting generally in males. However, many women have rigid cystoscopy performed in the clinic while the men have flexible cystoscopy. No studies to date have evaluated whether flexible cystoscopy is better tolerated in women compared to rigid cystoscopy in women in the clinic setting.
