Active clinical trials for "Urinary Retention"

The purpose of this study is to compare the prevalence of postoperative urinary retention between retained and non-retained urinary catheter in total knee arthorplasty with epidural anesthesia

This is an unblinded, multi-center, randomized, controlled, cross-over study assessing wheel-chair bound, male user preference and catheter characteristics of two intermittent urinary catheters. Subjects enrolled in the study will be randomized to order of catheter use. Individual participation will consist of approximately 1 week of product use. The null hypothesis to be tested is there no difference between catheters.

Post-operative urinary retention (POUR) is a frequent complication reported as ranging from 10 to 55% in the literature. In a recent retrospective study from Laliberte et al in Quebec City, we observed that 19% of the patients operated using transanal endoscopic microsurgery (TEM) had a post-operative urinary retention (POUR). Factors related to the patient, the tumor and the surgery were not observed to be associated risk factors. Tamsulosin has been shown as an effective preventive agent of POUR for certain ano-rectal and inguinal surgeries. The efficacy of this prophylactic therapy in transanal endoscopic microsurgery has not been studied yet and is unclear considering the particularities of this procedure. TEM uses a rigid proctoscope of four centimeters of diameter and creates a continuous pneumorectum (insufflation of the rectum during all the procedure). We think that these two elements, which cause local inflammation, may be part of the reason explaining the high incidence of post-operative urinary retention after TEM procedures. The objective of our multicenter clinical trial is to evaluate the effect of perioperative tamsulosin for the reduction of POUR in men, as well as the impact on the interventions and hospital admissions related to this complication.

ICU patients are at risk for catheter associated urinary tract infection. Frequently patients can't tell clinicians if they need to void if the catheter is removed. If clinicians know that an accurate volume measurement s of urine volume in the bladder can be obtained when the catheter is removed, catheters could be removed earlier and more frequently and thus possibly avoid an infection. For this study, measures with ultrasound (directly visualizing the bladder to measure), bladder scanner (partially blind measure with placement of scanner over the expected bladder location on the skin) and urine catheterized volume will be obtained. The investigators also want to know if the technology is user dependent. The study will include 2 levels of nurses RN and advanced practice RN (APRN) perform the bladder scanner. An APRN and MD will conduct the ultrasound. Ultrasound is technology primarily used by physicians but APRNs are using the technology technology more frequently. After these 4 measurements, the patient's nurse will perform an intermittent straight catheterization (catheter inserted, urine drained, and catheter removed) as the gold standard comparison.

Investigating whether pre-operative treatment with a selective alpha1-adrenoceptor antagonist affects the likelihood of male patients developing post-operative urinary retention following hernia repair.

The purpose of this study is to document the safety, the effectiveness, the continued performance at mid and long term, the morbidity and the percent of surgical revisions of the Interstim® therapy for up to 5 years in a representative sample of French centers under real-life conditions of use.

Retrospective case-control study. A substantial number of patients do not respond favourably to sacral neurostimulation (SNS) although clinically, they appear to have the same lower urinary tract dysfunction characteristics as the ones with good responses. This may be due to methodological issues (lead position) or patient selection. The purpose of this study is to improve and standardize lead position, in order to increase the patient response to test stimulation and to SNS treatment, and to decrease adverse events.

This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.

The goal of this cross-sectional, multicentric and descriptive epidemiological study is to assess the prevalence of chronic urinary retention (CUR) in elderly living in residential care for dependent elderly people in order to determine if there is an interest in offering them a bladder scan screening.

This study investigates efficacy, safety and childbirth experience in women receiving pudendal block during the final stage of delivery. It is an observational study and half of included primarous women recieve a pudendal block.
