Active clinical trials for "Urologic Neoplasms"

The study aims to investigate the rationale for LPN in patients with high-complexity renal tumors in terms of oncologic and functional outcomes.

The study described here is being conducted to prospectively confirm the performance of the ExoDx Prostate gene expression assay in patients presenting for an initial prostate biopsy and support of CE-marking the test for a European Union Launch.

Background: Upper tract urothelial carcinoma (UTUC) is a rare tumor associated with bladder cancer in up to 50% of cases. Its incidence is rising due to improved detection and bladder cancer survival. The diagnosis of UTUC is challenging because more than 35% of the standard biopsies can result inconclusive. The grading of UTUC cells, which delivers the most important data for the choice between a kidney-sparing surgery (KSS) and a radical treatment, is upgraded in 30% of radical nephroureterectomies. The follow-up of UTUC after KSS requires an invasive procedure as a diagnostic ureteroscopy for a minimum of 5 years, and urinary cytology has low diagnostic power. Objective: The aim of the study is to evaluate the accuracy (overall and stratified for grade) of a DNA methylation urine biomarker test (Bladder EpiCheckTM) in UTUC, and to compare it with current standard (urinary cytology). The secondary objective is to show its applicability in the specific clinical scenario of UTUC surveillance after kidney-sparing surgery and related cost-effectiveness. Design, Setting, and Participants: From February 2019 to February 2021, 80 consecutive patients candidates to ureteroscopy for suspicion of primary, recurrent or metachronous UTUC in one tertiary Referral Centers (Fundaciò Puigvert) giving written informed consent will be included in the study. Intervention: Bladder urine samples (> 10 ml) will be collected for cytology and for the methylation test before cystoscopy. Prior to semirigid and flexible ureteroscopy, urine specimens from the upper urinary tract will be obtained via a ureteral catheter.

In this randomized prospective single-blind study,American Society of Anesthesiologists physical status classification system ( ASA )I-II-III patients aged 50-80 years undergoing transurethral bladder resection will be randomly divided into two groups. First group will be covered with 41 centigrade degrees double layered cotton cloth. Second group will receive active prewarming. Core temperature of all patients will be monitorized via tympanic membrane. Skin temperature will be monitorized from 4 different body areas. Spinal anesthesia will be applied at the level of L3-L4 by a 25 Gauge quincke needle with a dose of 12.5-15 mg hyperbaric bupivacaine. Pinprick test will be used for sensorial block assessment. T10 sensorial block will be our goal. Hemodynamic parameters will be recorded. Skin temperature will be monitorized before and after spinal anesthesia and changes will be recorded. Operation time, amount and temperature of irrigation fluids, transfusion requirement, discharge time from postoperative care unit will also be recorded. Shivering score and thermal comfort scale will be used. The two groups will be compared for the temperature changes.

Cancer patients have an increased risk of perioperative complications undergoing surgery procedures. Postoperative complications caused by thrombembolic events after robot- assisted surgery in major urological procedures have been reported and associated with an increased lenght of stay in the hospital. We therefore aimed to investigate in a retrospective analysis 250 patients undergoing robotic-assisted radical cystectomy and prostatectomy procedures for risk factors for thrombembolic events in this specific patient population.
