NCT ID: NCT02919436 Recruiting - Clinical trials for Post-operative Urinary Retention

Decreasing Rates of Intraurethral Catheterization Postoperatively in Spine Surgery

Start date: March 2016
Phase: Phase 4
Study type: Interventional

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

NCT ID: NCT02684344 Terminated - Clinical trials for Post-Operative Urinary Retention

Prophylactic Tamsulosin Use for Prevention of Post-Operative Urinary Retention

Start date: February 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02414373 Completed - Clinical trials for Post Operative Urinary Retention

Effects of Thoracic Epidural Administered Ropivacaine Versus Bupivacaine on Bladder Function

Start date: April 2015
Phase: Phase 4
Study type: Interventional

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.
