Active clinical trials for "Urinary Retention"

After reconstructive pelvic surgery urinary retention occurs in up to 60% of patients requiring an indwelling catheter or self-catheterization (1-5). Up to 35% of women with acute retention experience urinary tract infections in the postoperative period (6, 7). Many women consider being discharged with a Foley catheter to be a surgical complication and describe catheter use as the worst aspect of their surgery(8). At this time there is no consensus within the field of Female Pelvic Medicine and Reconstructive Surgery (FPMRS) on how to best assess voiding function postoperatively. FPMRS providers both within the United States and around the world utilize a variety of void trial methods and varying criteria to determine adequacy of post-operative voiding efficiency (5). The traditional backfill assisted void trial method involves the assessment of a postvoid residual (PVR) volume obtained either via catheterization or bladder scan (3). Recently, there have been efforts to determine ways to avoid the assessment of a PVR as it is time-consuming and potentially exposes the patient to additional catheterizations (9, 10). Many FPMRS providers utilize the backfill assisted method without assessing a PVR and instead utilize a certain voided volume threshold to determine adequate voiding. However, to date, no one has directly studied this approach or compared the traditional backfill assisted void trial to a PVR-free backfill assisted void trial. By decreasing catheterization and creating a more efficient void trial method, the investigators hope improve patients' postoperative experience and reduce catheterization and risk of urinary tract infection (UTI). This study aims to compare two void trial methodologies in order to help standardize post-operative care in the urogynecology population. This study also has potential to lead to an overall change in our field and improve the postoperative course for women across the country and abroad.

Comparison incident of urinary retention in patients with vaginal surgery of pelvic organ prolapse, who removed urinary catheter at 24 hours versus 48 hours after surgery

Randomization (1:1) of male patients, over age 50, undergoing elective spine surgery to tamsulosin versus a placebo.

This is a prospective, comparative randomized study. Our study population includes women with pelvic organ prolapse undergoing a robotic assisted laparoscopic sacrocolpopexy. The two groups will include the study group, who will have their Foley catheter removed 6 hours post-op, and the control group who will have an indwelling Foley catheter overnight. The two groups will be assigned according REDCap randomization system.

It is common practice to insert a Foley catheter into the bladder to drain urine during and after a lung resection. Recently, there has been increasing interest in the potential risks associated with this catheterization, particularly with regard to infection. As thoracic surgery adopts minimally invasive surgical techniques, the need for urinary catheterization during surgery is being questioned since these less invasive surgeries are known to result in less post-operative acute pain, shorter length of stay, and other outcomes that tend to decrease overall anesthetic needs for this patient population. Thus, there is a need to investigate whether patients who have had a minimally invasive lung resection truly need the Foley catheter at all. This will be achieved by assigning patients to either an experimental no-catheter group or the standard of care routine urinary catheter group to determine if patients with no catheter experience different rates of complications. This pilot study will primarily determine if there is a difference in post operative urinary complications between the groups. It is hoped that this study will definitively determine whether a Foley urine catheter is a necessary procedure in the course of a minimally invasive lung resection.

The primary objective of this project is to compare the rate of postoperative voiding dysfunction in two voiding trials (the retrograde-fill technique versus the spontaneous-fill technique) after midurethral sling (MUS) procedures with tension-free vaginal tape (TVT) without any concomitant surgery.

Patients who were using anticoagulant or antiaggregant medications for any reason and underwent transurethral resection of bladder tumor (TUR-BT) or transurethral resection of the prostate (TURP) or open prostatectomy (OP) due to BPH will be compared with those who were not using anticoagulant or antiplatelet medication. The rates of postoperative clot retention, presence of hematuria, reoperation due to hematuria, blood transfusion and re-admissions due to hematuria in the first postoperative month will be compared.

This study will look at how pre-test anxiety levels affect the reproducibility of symptoms during routine urodynamic testing in women. Urodynamics is a test that assesses the function of the lower urinary tract, including the bladder.

A randomized, open label, controlled, parallel group study to investigate difference between regional standard procedure and a novel modified procedure (using an additional novel device to facilitate gel installation) for changing long-term indwelling urinary catheters.

Post operative urinary retention ( POUR) is caused by sympathetic activation of the internal urethral sphincter after surgery. The smooth muscles of the around the internal urethral sphincter have been demonstrated to be rich in alpha-1 adrenergic receptors. Our research idea is novel because there has been no prior prospective study conducted using alpha-blockers to reduce post-operative urinary retention in patients undergoing inguinal hernia repair. The proposed research is important as existing studies that sought to understand POUR have merely established the risks factors involved. Despite so, the incidence of POUR remains high and no studies to date have investigated the use of specific interventions to reduce the risk of POUR. This is essential as patients who develop POUR have also been successfully shown to have significantly longer length of hospitalisation. Besides, the development of POUR can also cause significant pain/discomfort, increase risks of long-term urethral catheterisation and predispose patients to urinary tract infections
