Urinary Retention Postoperative

The purpose of this research is to see if the use of tamsulosin can decrease both the incidence and duration of urinary retention, as well as hospital length of stay following spine surgery.

The objective of the study is to determine the effectiveness of postoperative Tamsulosin in reducing the duration of acute postoperative urinary retention (POUR) following pelvic reconstructive surgery through a double blind, randomized placebo-controlled trial.

This investigates the outcomes of a surgical technique using the patient's own abdominal wall muscles to help contract the bladder in patients with urinary retention

Revision total knee arthroplasty (rTKA) is a frequently performed procedure. Adequate pain management is an important feature, especially for fast-track and Enhanced Recovery After Surgery (ERAS) programs. The multimodal approach, including single shot or continuous nerve blocks with catheters and spinal or epidural morphine, is a stablished strategy. Although the administration of intrathecal morphine (IM) has been shown to significantly reduce pain scores, it is not free of adverse effects. Postoperative urinary retention (POUR) is possible and might increase the risk of periprosthetic infection. The purpose of this study is to compare patients undergoing rTKAS under spinal anesthesia with IM to patients undergoing the same procedure, under the same anesthetic technique, but with no IM, for POUR and postoperative pain related outcomes. All patients will have single shot and continuous adductor canal block (CACB) and single shot IPACK (interspace between the popliteal artery and the posterior knee capsule) block. The hypothesis is that postoperative pain control is comparable between the groups, with lower incidence of POUR in patients with no IM given.

This study aims to compare two medications, dexmedetomidine and fentanyl, when used alongside a commonly used spinal anesthetic called bupivacaine in patients undergoing lower limb surgery. The main focus of the study is to see which combination causes fewer problems with urination after surgery - a condition known as postoperative urinary retention (POUR). POUR can lead to discomfort, delayed recovery, and a need for catheterization. Dexmedetomidine is a newer drug that may help reduce this problem compared to fentanyl, which is more commonly used but may increase the risk of urinary retention. This trial will help determine which medication combination provides better pain relief while reducing urinary side effects. The study is being conducted as a randomized, double-blind trial at a hospital in Nepal and will include 190 adult patients. \-

The objectives of this study are to determine the feasibility of conducting a full-scale randomized control trial comparing the efficacy of tamsulosin compared to placebo in reducing post-operative urinary retention in people undergoing elective thoracic surgery.

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.
