Filter by:Rationale: Cystoscopy and cytology, the current 'gold standard' for detection and follow-up of primary and recurrent bladder cancer have some limitations. CLE, a high resolution imaging technique, that can be used combined with endo-urological procedures, seems promising to improve diagnosis of bladder cancer. The diagnostic accuracy of cystoscopic applied confocal laser endomicroscopy (CLE) still has to be defined. Objective: To directly correlate CLE images with histopathology, and identify and define CLE characteristics of normal urothelium, benign bladder urothelium, and bladder tumors (low-grade, high-grade and carcinoma in situ (CIS)) of the lower urinary tract. Primary objective: to develop descriptive image interpretation criteria and a classification of CLE images of bladder tissue through a review of prospectively obtained CLE videos from bladder tissue correlated with histopathology. Secondary objectives: - Assessing procedure related adverse events of CLE - Assessing technical feasibility of CLE - To develop a CLE image atlas for urothelium of the lower urinary tract (normal, benign, low-grade or high-grade and CIS)
In patients undergoing spinal anesthesia, the investigators used an Infra-red camera and a respiratory volume monitor to determine the accuracy of the ventilation rate of the infra red camera by measuring the respiratory rate, ventilation volume, and ventilation volume with respiratory volume monitor.
Conventionally, transurethral standard resection (SR) of bladder tumour is performed in a piecemeal manner. Transurethral en bloc resection (EBR) has been described as an alternate surgical technique in bladder tumour resection. By preventing tumour fragmentation and ascertaining complete tumour resection by histological assessment of the EBR specimen, we hypothesized that EBR could reduce disease recurrence as compared to SR.
In urologic robotic surgery with steep Trendelenburg position, maintenance of cardiac preload and cardiac output is important for clinical prognosis. Previous studies reported the positive end-expiratory pressure (PEEP)-induced increase in central venous pressure (CVP) could be a accurate predictor of fluid responsiveness in cardiac surgical patients. The authors attempt to evaluate the predictability of PEEP-induced increase in CVP as well as stroke volume variation in urologic robotic surgery with Steep Trendelenburg position.
A study to validate, in a prospective manner, the ability of the predefined Genomic Health bladder cancer assay to detect recurrence in patients undergoing surveillance for non-muscle invasive bladder cancer.
This clinical study is designed to evaluate the diagnostic performance of VisioCyt test, which would improve the early diagnosis of bladder cancer in order to optimize the management of individual patients as part of a cancer diagnostic monitoring. The diagnostic method of VisioCyt® device is based on the analysis by transmission and fluorescence, of urinary cytology slides prepared according to the protocol VisioCyt.
Gas exchange disturbance frequently occurs in steep Trendelenburg position during robot-assisted laparoscopic prostatectomy or cystectomy. Due to increased intrathoracic pressure and absorbed carbon dioxide (CO2) gas insufflated into abdominal cavity, hypercapnia as well as hypoxia may occur. Inverse ratio ventilation or prolonged inspiratory time during mechanical ventilation has been reported to be improve gas exchange in adult respiratory distress syndrome. The investigators attempt to test the hypothesis that prolonged inspiratory time may improve the gas exchange during robot-assisted laparoscopic urologic surgery.
This Phase II, single-arm study is designed to evaluate the effect of atezolizumab treatment in participants with locally advanced or metastatic urothelial bladder cancer. Participants will be enrolled into 1 of 2 cohorts. Cohort 1 (reported here) will consist of participants who are treatment-naïve and ineligible for cisplatin-containing chemotherapy. Cohort 2 will contain participants who have progressed during or following a prior platinum-based chemotherapy regimen. The results of the second cohort are reported separately (NCT02108652). Participants in both cohorts will be given a 1200 milligrams (mg) intravenous (IV) dose of atezolizumab on Day 1 of 21-day cycles. Treatment of participants in Cohort 1 will continue until disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) or unmanageable toxicity. Treatment of participants in Cohort 2 will continue until loss of clinical benefit or unmanageable toxicity.
The purpose of this study is to learn whether it is feasible to use the LifeScience Technologies application (LST app) in patients undergoing radical cystectomy with the eventual goal to reduce complications and readmissions to the hospital after surgery.
Patients scheduled for a cystectomy at Charleston Area Medical Center (CAMC) will be enrolled into a randomized, double blinded clinical trial to assess if postoperative pain and ileus are reduced by perioperative intravenous lidocaine infusion versus placebo. The hypothesis is that patients receiving the lidocaine infusion will experience better pain control and ileus resolution. It is believed that lidocaine patients will also have less opioid requirement, less mortality, a shorter length of stay, less nausea /vomiting, and fewer adverse events.
