Active clinical trials for "Urologic Diseases"

Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.

Demonstrate and compare the 3D morphology of the bladder wall in full and drained states with 2 different kinds of bladder catheters in place. (Foley Catheter vs. Cystosure Catheter)

This study aims to develop and validate the first set of patient-reported outcome measures for recurrent urinary tract infection (UTI): the Recurrent UTI Symptom Scale and the Recurrent UTI Impact Questionnaire. These tools could be used in clinical practice, clinical trials and research to gather an insight into a patient's perspective of their recurrent UTI symptom severity and its impact on their life, as well as determining any possible improvement or other change in their condition due to interventions (e.g. antibiotic treatment).

The investigators will assess the feasibility of replacing fluoroscopy/iodinated contrast with ultrasound/sulfur hexafluoride lipid-type A microspheres during routine urodynamic studies.

Evaluation of the influence of the diuretic injection timing (F+0 Vs F-15) on the dynamic 99mTc- DTPA renal scintigraphy for the diagnosis of suspected obstructive uropathy in adult hydronephrotic patients.

Since the outbreak of COVID-19 hit Spain in March 2020, most of the elective surgeries have been canceled everywhere. As soon as the epidemiology phase of the pandemic changed and the restrictions have been eased, different protocols have been put in place to screen patients for SARS-CoV-2 before surgery in order to reduce the spreading of the disease in hospitalized patients. To the best of the current state of knowledge, no recommendations or protocols have been established to guide surgeons in dealing with patients developing unspecific symptoms after surgeries, which could sign either of a post-op complication or COVID-19. The investigators have developed an enhanced pre and post-surgical protocol both to screen patients for COVID-19 before surgery and to promptly identify those patients suspicious for the viral infection during the post-op.

The function of the lower urinary tract is simple - urine storage and voiding. However, despite this simplicity of function, the control of the lower urinary tract is a rather complex, multilevel process (urothelium, detrusor, peripheral nerves, spinal cord and higher cerebral centres) and the mechanisms involved remain poorly elucidated. This study is designed to gain a more in depth understanding of the lower urinary tract function. Using bladder biopsies, tissue staining for characteristic markers present on nerves and other cells will be performed. We hypothesize that certain markers are altered in disease and turn back towards the control level of healthy people or patients with successful medical treatment.
