Active clinical trials for "Urinary Retention"

The purpose of the study is to compare alfuzosin GITS once daily versus placebo in achieving a successful TWOC after AUR due to BPH, among Chinese males in Hong Kong, and in delaying or avoiding a TURP.

This randomized open-label study will be comprised of 2 cohorts: one control group and one treatment group. The trial will be conducted as an open label randomized trial to evaluate the efficacy of tamsulosin in the prevention of post-operative urinary retention. The study will include pre- and post-surgical evaluations of patients including symptoms of urinary retention and any adverse effects contributable to the study medication.

Acute urinary retention is one of the most common complications after surgery and anesthesia. Micturition depends on coordinated actions between the detrusor muscle and the external urethral sphincter. Under the influence of epidural analgesia, patients may not feel the sensation of bladder filling, which can result in urinary retention and bladder overdistension. Overfilling of the bladder can stretch and in some cases permanently damage the detrusor muscle. Because epidural anesthesia can be performed at various levels of the spinal cord, it is possible to block only a portion of the spinal cord (segmental blockade). Thoracic epidural analgesia with bupivacaine significantly inhibits the detrusor muscle during voiding, resulting in clinically relevant post void residuals which required monitoring or transurethral catheterisation. This bladder muscle inhibition is comparable to a motor blockade. The epidural administration of ropivacaine during labour results in a clinically relevant reduction of motor blocks. The hypothesis is that thoracic epidural analgesia with the local anesthetics ropivacaine leads to less significant changes in bladder function than bupivacaine as a control group, in patients undergoing lumbotomy incision for renal surgery.

This is a prospective, open-label, Phase 1, single center study evaluating the safety and efficacy of Autologous Muscle Derived Cells as a treatment for chronic Underactive Bladder.

Assess feasibility and safety of the Prostatic Urethra Lift (PUL) procedure in patients with acute urinary retention secondary to benign prostatic hyperplasia (BPH).

Sacral neuromodulation (SNM) is a minimally invasive secondary treatment for overactive bladder syndrome (OAB) or for non-obstructive urinary retention (NOR), when refractory to conservative treatment. Success rates range from 70 to 80%, and good long-term results are reported. The working mechanism of SNM is not completely understood, and the only prognostic factor for good response to this treatment is a successful test stimulation period. There is no consensus on the duration of this test stimulation period. The experience in our clinic during test stimulation period is that for responders it takes up to one week to achieve maximal effect, after the system is turned 'on'. On the other hand the investigators notice that after turning the neuromodulation system 'off', it will take a few hours for symptoms to return to the baseline situation. The fact is: no information concerning the so called "time of onset" and "time of offset" (or popular called: wash-in / wash-out) of sacral neuromodulation is available in current literature.

The investigators hypothesize that many parturients can, in fact, spontaneously micturate with low dose combined spinal epidural analgesic doses given for labor and that Foley catheterization is unnecessary in the majority of these parturients. At Prentice Women's Hospital, almost 9000 women annually receive neuraxial labor analgesia and 98% of those receive Foley catheters. By potentially reducing the necessity for Foley catheters, the investigators should be able to ultimately reduce the rate of bacteriuria, urinary tract infections and urethritis leading to unnecessary treatment with antibiotics, as well as reduce costs of placing unnecessary Foley catheter.The hypothesis is parturients receiving low dose combined spinal epidural analgesia for analgesia after induction of labor who are randomized to a spontaneous micturition protocol will require fewer Foley catheter placements and demonstrate a lower incidence of positive urine culture postpartum than those who undergo standard Foley catheter placement.

Background: Radical hysterectomy is an important therapy for early cervical cancer. Disfunction of urinary dynamics is the most common postoperative adverse effects, which had negative impact on patients' quality of life. Nerve sparing radical hysterectomy (NSRH) could reserve inferior hypogastric plexus (IHP) innervating bladder, hence improving postoperative urinary dynamics. Furthermore impact of different energy instruments on urinary dynamic isn't clear. Objectives: This study is to compare urinary dynamics before and after NSRH, and to analyze the difference between BiClamp forcep (BiClamp® forcep, ERBE Elektromedizin, GmbH, Tuebingen, Germany) and water jet (ERBEJET®2) about the effects of dissecting IHP. Study population: Cervical cancer of FIGO IB stage, among which 120 cases are enrolled to randomly allocated to BiClamp group or water jet group. Intervention: Patients accept NSRH which all will be accomplished by Professor Ming Wu. Methods: All surgical patients are accessed via urinary dynamics before and four months after NSRH. On the 14th day after surgeries, urinary catheter will be removed and residual urine volume (RUV) will be measured. For patients of RUV > 100 ml, urinary catheter will be replaced. Primary study endpoint: the successful rate of removing urinary catheter on the 14th day after NSRH. Secondary study endpoint: urinary dynamics four months after NSRH.

To investigate the effect of tamsulosin on the development of post-operative urinary retention (PUR) after elective laparoscopic inguinal hernia repair (LIHR). This will be accomplished by administering a pre-operative dose of tamsulosin. The primary outcome is the rate of urinary retention necessitating straight catheterization or insertion of foley catheter prior to discharge.

The aim of the study is to evaluate what is the most effective catheterization duration to resolve covert and overt postpartum urinary retention following vaginal delivery and caesarean delivery, with the highest patients' satisfaction.
