Active clinical trials for "Urinary Retention"

To evaluate the ease of use and comfort of a new urinary catheter, the Uro-Ease, as used in the Clean Intermittent Catheterization (CIC)process.

This is a prospective, comparative, multicenter, randomized controlled trial. The aim of this study is to compare the efficacy, safety and quality of life within patients with acute urinary retention managed by the intermittent catheterization compared or indwelling Foley catheter.

The purpose of this study is to assess the feasibility and safety of Prostate Artery Embolization (PAE) in patients suffering of Acute Urinary Retention (AUR) in the context Benign Prostatic Hypertrophy (BPH).

The Catheter Science M3 "Mini Catheter" has been developed for management of urinary retention. This temporary device allows for normal functioning of the external striated sphincter. The design contributes to its atraumatic insertion and removal. It is a short catheter segment which is attached to a monofilament suture which runs thru the lumen of the urethra and is attached to a small plastic "bobber". This study is designed to validate the reduction in these adverse effects: The suture to the outside allows for repositioning should the device slip back into the bladder and facilitates removal. With volitional voiding and competent external sphincter, patients are able to void spontaneously without the need of a collection device and are continent. The design enhances the flow characteristics and reduces post void residual. Since the M3 does not have a tubular segment thru the tip of the penis or sphincter, biofilm production is eliminated.

It is estimated that over 10% of men above the age of 60 will experience an episode of urinary retention over a period of 5 years and will need urethral catheter. Some of these patients are discharged from the hospital with urethral catheter, for them to attend a Trial Without Catheter (TWOC) clinic at a later date for catheter removal. Traditionally after catheter is removed in the clinic the nurse has to wait for up to 5 hours before the patient get the urge to pass urine and empty the bladder. The main objective of this study is to see the effect of catheter valve on the length of clinic stay (timing of discharge)for the patients (men age 60-85) after catheter is removed. In this study after randomization, patients in Group A (catheter valve group) will be given a catheter valve before they are sent home with the catheter.They will be asked to close the valve 3-4 hours (time required for adequate filling of bladder, which means minimum of 250 mls in bladder with natural filling) before their appointment. It is very likely that by the time these patients are seen in the TWOC clinic their bladder is already full and they will void soon after removal of catheter.The patients in Group B (control) will go home with free drainage catheter and urine bag (standard catheter removal). These patients on arrival, in the TWOC clinic will have an empty bladder when their catheter is removed, they will then drink plenty of fluids in the clinic and wait for their bladder to be full before they void spontaneously. This study will last for one year after approval by ethical committee. The time saved in this process would lessen patient anxiety, lead to more patients being reviewed in clinic and therefore reduced waiting times in TWOC clinics and will save money.

The study is to collect information from patient charts and patient questionnaires to evaluate the effects of nerve stimulation therapy on urinary dysfunction.

Acute urinary retention is a complication of hysterectomies that can result in bladder over-distension and long term bladder dysfunction. The incidence of acute urinary retention after total laparoscopic hysterectomy (TLH) has been reported to be anywhere between 4% and 34%. Studies have varied in the method of post-operative bladder challenge and the modality of hysterectomy included. Moreover, most of the published studies are retrospective chart reviews or prospective observational studies, with a lack of randomized controlled trials. Risk factors for urinary retention include type of anesthesia used, how the hysterectomy is performed, use of post-operative narcotics, pre-operative urinary retention, and possibly aggressive bladder dissection. With the increased trend towards same-day discharge following TLH, urinary retention may cause unnecessary patient distress and a worsened post-operative course. Standardization of post-hysterectomy bladder challenge and identification of risk factors for urinary retention may aid in preventing urinary retention or acute bladder dysfunction. The primary objective is to compare the rate of void trial failure after TLH with the backfill technique versus the autofill technique.

There has been preliminary data showing that pyridium can decrease the risk of difficulty urinating after midurethral sling. This study is designed to have two groups of patients. One group will receive pyridium pre-operatively, while the other group will have routine preoperative care. Both groups will have their bladder tested prior to going home. It will be evaluated if there is a difference in the difficulty to urinate post-operatively in both groups.

The objective of this study is to compare the incidence of postoperative urinary retention related to spinal anesthesia with morphine and spinal anesthesia associated with peripheral blockade in orthopedic procedures of lower limbs. Secondary objectives are assessing the incidence of nausea and vomiting; postoperative pain and opioid consumption at 24 hours after surgery with each of the techniques. A total of 52 patients submitted to a lower limb orthopedic procedure were randomized to the intervention groups: spinal anesthesia with morphine versus spinal anesthesia without opioid associated with peripheral nerve block. After surgery, bladder ultrasound will be performed in post-anesthesia care unit to identify urinary retention and patients will be followed for 24 hours to assess outcomes.

Purpose: The purpose of this study is to determine if two different methods of performing a postoperative voiding trial are equivalent in evaluating urinary retention after gynecologic surgery. Participants: The participants in this study will be women who have undergone gynecologic surgery at UNC-Chapel Hill.
