Filter by:Outpatient midurethral surgery is a frequent surgery. It is performed either under general anesthesia or neuraxial anesthesia. A frequent complication is postoperative urinary retention requiring urinary catheterization, which implies a higher infectious risk. The investigators compared the complication rate after TVT surgery depending on the type of anesthesia.
The Catheter Science C3 "Umbrella Catheter" has been developed for management of urinary retention in patients who are either using a Foley or Self Intermittent Catheter. This device is inserted into the bladder in an extended state and once the stylet is removed the device folds into collapsed state. A thread is attached to the device and traverses thru the urethra and is attached to a bobber. With gentle traction on the thread the device engages the bladder neck and the central tube extends which allows for the flow of urine. Once voiding is complete, the thread is released and the device collapses back to the folded state into the bladder. Each voiding cycle is accomplished in a similar fashion. This is a novel technique in which the bladder is catheterized with the device from within the bladder into the bladder neck and urethra. The standard self catheter technique is for placement of a catheter from the outside into the urethra and into the bladder.
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.
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.
Prospective observational 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 (LUT) dysfunction characteristics as the good responders. 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.
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 investigators intend to compare the rate of urinary retention among female patients after vaginal delivery under epidural anesthesia, depending on bladder catheterization type, either by a foley catheter inserted adjacent to epidural anesthesia or intermittent catheterization applied every 4 hours during labor.
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 aim of the study is to compare the safety and efficacy of ESWL and visual cystolitholapaxy in management of calcular acute urine retention.
The purpose of the study is to compare the risk of being unable to urinate shortly after surgery, also called acute post-operative urinary retention (POUR) between spinal and general anesthesia in women who undergo outpatient pelvic organ prolapse with stress urinary incontinence surgery.
