Active clinical trials for "Urinary Retention"

A randomized controlled study will be conducted, with two arms. Postpartum women experiencing urinary retention will be randomized into one of the two following arms: Arm 1: Subjects will be exposed to vapor of peppermint oil Arm 2: Subjects will be exposed to vapor of placebo (mineral oil) Outcome variables include resolution of urinary retention, time to spontaneous urination, volume of spontaneous urination, frequency of urinary catheterization, and patient satisfaction.

In this study a total of 150 parturients undergoing cesarean delivery under spinal anesthesia will be randomized to have their urinary catheters kept in place for 8, 10 or 12 hours. The incidence of urinary retention and interventions needed for any potential urinary retention will be assessed.

Millions of Americans are suffering from underactive bladder (UAB). The impact of severe UAB, i.e. non-obstructive urinary retention (NOUR) on quality of life is significant because current treatment for non-obstructive urinary retention requires intermittent self-catheterization or an indwelling suprapubic catheter. Currently an effective drug for non-obstructive urinary retention does not exist. It is a therapeutic challenge for clinicians to successfully treat non-obstructive urinary retention. Sacral neuromodulation has been approved by the FDA since 1999 to treat non-obstructive urinary retention. It achieves >50% improvement in bladder emptying (reducing the frequency of self-catheterization or increasing voided volume) in just over half of the patients. Sacral neuromodulation requires surgical implantation of a stimulator and a lead with 4 electrodes. The surgery and implant are invasive and expensive, preventing a broad application of this effective therapy to many non-obstructive urinary retention patients. The goal of this study is to develop a novel non-invasive neuromodulation therapy for non-obstructive urinary retention as an alternative. Specifically, the investigators will explore the possibility to translate into humans a recent discovery in cats of an excitatory reflex from the superficial peroneal nerve to the bladder to treat non-obstructive urinary retention. Therefore, in this study the investigators propose to develop a non-invasive, transcutaneous neuromodulation therapy for non-obstructive urinary retention that can be administered at home.

The general purpose of this study is to assess the preliminary effectiveness and cost-effectiveness of the T-Control® catheter versus the Foley type catheter in patients with Acute Urine Retention.

Post-market clinical follow-up for continued assessment of safety and performance to confirm long-term outcomes of the InterStim Micro System for sacral neuromodulation.

The primary aim of this study is to compare the rate of acute urinary retention (AUR) after immediate compared to early (24-hours) removal of urinary catheter (UC) in patients undergoing minimally invasive colorectal resection. The study hypothesis is that immediate UC removal is non-inferior to 24-hours UC removal in terms of AUR rate. The secondary outcomes focus on goals that could be positively impacted by the immediate removal of the UC at the end of the surgery. In particular, the rate of urinary tract infections, perception of pain, time-to-return of bowel and physical functions, postoperative complications and postoperative length of stay will all be measured.

Various studies have shown that the risk of suffering a urinary retention after knee or hip prosthesis surgery is 10-80%. The aim of the study is to reduce this riks. For this purpose, it is investigated whether a previously known drug (tamsulosin) which is used in bladder emptying disorders, can achieve a reduction in urinary retention after surgery. After the patients agree to participate in the study, they are examined in our urological clinic. Uroflowmetry is performed with sonographic residual volume measurement and prostate volume measurement. Furthermore, a standardized Voiding questionaire (IPSS) is completed. This study is conducted as a double-blind study using a placebo control group. The drug / placebo is taken once a day, five days before and two days after surgery. Subsequently, it is observed whether it comes to a urinary retention or not. After the operation, no further urological checks are planned or needed.

Arthroplasty increases the risk of postoperative urinary retention. Treatment of postoperative urinary retention is indwelling or intermittent catheterization. The need for catheterization is most commonly determined with an ultrasound scanner. Catheterization increases the risk of urinary tract infection, which may further lead to haematogenic infection of the artificial joint. There is no evidence of an optimal way to monitor the onset of spontaneous urination. The aim of the study is to determine whether monitoring the onset of spontaneous urination after fast track knee arthroplasty is safe based on symptoms alone without ultrasound monitoring.

Postoperative urinary retention is a frequent complication of spinal surgeries and impacts a large portion of this population which results in increased morbidity as a result of increased number of catheterizations, urinary tract infections (UTIs) and prolonged hospital stays. With the addition of Tamsulosin, the investigators would anticipate a reduction in the incidence and duration of postoperative urinary retention and therefore a reduction in morbidity related to treatment of urinary retention as well as shortened hospital stays.

The study will be a prospective, randomized controlled trial comparing prostatic urethral lift (PUL) versus transurethral resection of prostate (TURP) in benign prostate hyperplasia (BPH) patients with urinary retention. The primary objective of this study is to compare the catheter-free rates of PUL vs TURP. Secondary objectives include comparison of complications rates, cost effectiveness, patient satisfactory, symptom scores, quality of life measures and urodynamic parameters.
