Filter by:Patients with urothelial high risk non-muscle invasive bladder cancer patients will be treated with intravesical electromotive drug administration/mitomycin (EMDA/MMC) after bacillus Calmette-Guerin (BCG) failure. Patients are scheduled for an initial 6 weekly treatments, a further 6 weekly treatments for non-responders and a followup 10 monthly treatments for responders. Complete response will be defined as histological disappearance of malignancy on bladder biopsy and resolution of abnormal cytological findings after treatment. Time to first recurrence, time to progression, overall survival, and disease-specific survival wil be estimated by use of the Kaplan-Meier method.
In the investigators's previous work, measurements of intra-prostatic concentrations of sex steroids were determined on samples taken from the operating room using a punch. In order to study the in-vivo intra-prostatic concentrations of sex steroid, it is necessary to validate a measurement technique performed on samples obtained by a biopsy needle used in standard care for prostate biopsy punctures allowing the diagnosis and follow-up of prostate cancer. The aim of this project is to validate this measurement technique carried out on samples obtained by the biopsy needle and to define the optimal number of carrots obtained by biopsy offering dosage results comparable to the punch.
To investigate the use of antibiotic prophylaxis in patients undergoing TURP and TURB. The investigators set up a prospective, randomized controlled trial in which (after exclusion of risk factors) patients will be randomized in receiving levofloxacin (Tavanic) orally or no antibiotics. The exclusion criteria for TURP are a pre-operative transurethral catheter or > 100 urinary white blood cells in the pre-operative urine sample. The exclusion criteria for TURB are a pre-op catheter or clinical signs of infection.
Antimicrobial prophylaxis in urological procedures is aimed to reduce the risk of local and systemic postoperative infections such as urinary tract infection or surgical site infection. It should be recommended only when the potential benefit exceeds the anticipated risks and costs. However, a wide variation in the use of periprocedural prophylactic antibiotics has been demonstrated, which frequently is incurred as an inappropriate selection of antimicrobials, inadequate schedule of administration or excessive duration of prophylaxis. The increase in multidrug resistance of antibiotics in recent decades has been associated with its misuse, resulting in an increased rate of morbidity and mortality, prolonged hospital stays and increased care costs. Specifically, resistance to fluoroquinolones has increased its prevalence, a group of antibiotics widely used in urology. Therefore, local resistance patterns should be considered before following recommendations, especially in populations with poor control of antimicrobial use. Transurethral resection of bladder (TURB) has become a frequent surgical procedure, as it is the main diagnostic and therapeutic tool for bladder cancer, representing the ninth most common malignancy in the world. However, no recent randomized clinical trial has investigated antimicrobial prophylaxis for TURB. It is well known that an expected complication of TURB is urinary tract infection (UTI), which is the most common healthcare related infection worldwide. Under this premise, a randomized clinical trial is proposed to analyze the current panorama of UTI as a transcendent postoperative complication of TURB, under the context of the new emerging resistance parameters. The use of fosfomycin trometamol is proposed as a good potential option for urological procedures due to its high activity against multidrug-resistant gram-negative bacteria and its favorable pharmacokinetic parameters that guarantees wide tissue penetration and a high urinary concentration, in a single dose, the which will be compared with the control group with traditional prophylaxis (amikacin). The relative risk of UTI will be estimated, as well as the attributable risk of the main risk factors associated with this infection, allowing a better characterization of this population for adequate decision making regarding this clinical challenge.
The purpose of the study is to see if treatment with nivolumab plus bempegaldesleukin or nivolumab alone, before and after surgery to remove the bladder, is more effective than surgery alone in participants with high-risk urothelial cancer, including muscle-invasive bladder cancer who are not able to receive cisplatin chemotherapy.
This study will be conducted in adult subjects diagnosed with any form of an advanced or metastatic solid tumors including urothelial carcinoma for which standard therapy is no longer effective or is intolerable. This is a phase 1, multi-center, open label study designed to assess safety and tolerability of IK-175 as a single agent and in combination with nivolumab, to determine the recommended phase 2 dose (RP2D). Disease response, pharmacokinetics (PK), pharmacodynamics, and response biomarkers will also be assessed.
The current study aimed at prospectively assessing the performance of IUC as a predictive tool for residual tumor after primary TURBT of NMIBC, and possible future recurrence.
In this study, the new aScope 4 Cysto is used to see how well it visualizes the lower urinary tract, and if this new flexible cystoscope performs as well as other routinely used cystoscopes. This study will be done in patients who have been diagnosed with bladder lesions and who will undergo surgery via the urethra to remove these lesions. The surgery is done under general anesthesia. After being brought under anesthesia and before removal of the lesion(s), the new flexible cystoscope is tested. The cystoscope will be used to visualize the urethra and bladder. Data will be collected on the number of the lesions that can be seen using the new cystoscope. During the planned surgery a resectoscope or rigid cystoscope will be used to confirm the number of lesions. The data will be used to show how well the cystoscope visualizes the lesions in comparison with routinely used cystoscopes. It will give information on how well the structures of the urinary tract and bladder can be viewed including any abnormalities that are present.Data will also be collected on the handling of the cystoscope: how well the cystoscope moves into the lower urinary tract, and how well it can be navigated through the lower urinary tract.
Treatment of recurrent bladder cancer with dendritic cells
there are many techniques for uretero-ileal anastomosis some of them are antirefluxing for protection of the upper urinary tract with many complications including strictures and pyelonephritis with difficult technical issues and long operation time so a modified technique combining the 2 ureter by wallace technique and implanted them in a single trough in the neobladder making the surgery easier and shorter. this technique was done after informed consent in 45 patients with muscle invasive bladder cancer candidate for radical cystectomy and ileal neobladder diversion
