Active clinical trials for "Urinary Retention"

The aim of this study is to investigate the impact of an active voiding trial compared to a passive voiding trial on time to discharge following a planned same day discharge laparoscopic hysterectomy. The investigators hypothesize that performing an active voiding trial will assess urinary function and lead to a reduction in length of stay.

Trial of void (TOV) is a diagnostic test performed on all women who undergo prolapse repair or incontinence surgery, due to the importance of diagnosing postoperative urinary retention (POUR). Incidence of POUR may be as high as 62% in some studies. Timely and accurate diagnosis is important to avoid complications such as urinary tract infection, bladder overdistension, and permanent bladder injury. Despite the frequent use of TOV, there is no gold standard for the test, and it likely has poor specificity, leading to discharge of more patients with catheter than required. This prospective cohort study will seek to establish evidence-based optimal parameters for spontaneous trial of void, a TOV modality that has merit for further evaluation given lower theoretical risk of urinary tract infection.

The purpose of this study is to compare, for each patient, dosimetry of organs at risk (bladder, rectum, sigmoid, small bowel) in two bladder distension procedures (emptied by a urinary catheter or filled with 120cc) during PDR 3D image-guided brachytherapy of cervical cancer.

The urinary tract infections are common in children. It is estimated that about 3% of girls and 1% of boys suffer from a urinary tract infection before the age of 11 years. A prompt diagnosis and treatment are necessary for the prevention of morbidity and long-term sequelae. Currently, there are different methods of urine collection, such as suprapubic aspiration, the survey, the collection bag and the jet medium collection. They have in common to be time-consuming, invasive in some cases, providers of contaminated levies for others and impossible in children incontinent for the last. A Spanish study developed a new collection technique, for kidney and bladder stimulation, noninvasive, in the new-born to 30-day months. The results are promising with a success rate of over 85% within a period of about 45s. No study has looked at a broader pediatric population, including children from birth to age of acquisition of walking. We hypothesize that it is possible to obtain urine in less than 3 minutes, noninvasively, in infants who have not acquired the works for which a urine sample is required.

The purpose of this study was to evaluate whether there is a difference in long-term outcome between patients screened with the percutaneous nerve evaluation (PNE) and first stage tined lead procedure (TLP).

Acute urinary retention is one of the most common complications after surgery and anesthesia. Overfilling the bladder can stretch and damage the detrusor muscle, leading to atony of the bladder. It can occur in patients of both sexes and all age groups and after all types of surgical procedures. Micturition depends on coordinated actions between the detrusor muscle and the external urethral sphincter. Motorneurons of both muscles are located in the sacral spinal cord and coordination between then occurs in the pontine tegmentum of the caudal brain stem. Motorneurons innervating the external urethral sphincter are located in the nucleus of Onuf, extending from the S1 to the S3 segment. The smooth detrusor muscle is inner-vated by parasympathetic fibers, which reside in the sacral intermediolateral cell group and are located in S2-4. Sympathetic fibers innervating the bladder and urethra play an important role in promoting conti-nence and are located in the intermediolateral cell group of the lumbar cord (L1-L4). Most afferent fibers from the bladder enter the sacral cord through the pelvic nerve at segments L4-S2 and the majority are thin myelinated or unmyelinated. Because peridural anesthesia can be performed at various levels of the spinal cord and with varying concentrations of local anesthetic, it is possible to block only a portion of the spinal cord (segmental blockade). So it seems logical that peridural analgesia from a Th 2-4 to Th 10-12 will have no influence on the micturition reflex. Studies on the urodynamic effects of various anaesthetic agents are rare. Under the influence of epidural analgesia, patients may not feel the urge to urinate, which may result in urinary retention and bladder over distension. Spinal and epidural opioid administrations influence the function of the lower urinary tract by direct spinal action on the sacral nociceptive neurons and autonomic fibres. It is therefore a common practice for bladder catheterisation in the presence of spinal or epidural anesthesia. The excessive use of a transurethral catheter is undoubtedly associated with significant morbidity such patient discomfort, urinary tract infections, catheter entrapment, bladder calculi formation, urethral trauma and stricture. The risk of infection with a single catheterization is 1-2% and can rise to 3 to 7 % a day. There has yet been no consensus for appropriate catheterisation strategy and urodynamic changes under thoracic epidural anesthesia are still unknown. We expect that a better knowledge on the bladder function under epidural analgesia could lead to a more restrictive use of perioperative transurethral catheters. Our hypothesis is that thoracic epidural analgesia does not influence lower urinary tract function in the male and female. Therefore transurethral catheterization is not mandatory for all patients with thoracic epidural analgesia. Differences in post void residual urine volume and urodynamic examinations before and during thoracic epidural analgesia will be analyzed in 16 men and 16 women undergoing open kidney surgery/lumbotomy who receive thoracic epidural anesthesia perioperatively.

The purpose of this research study is to compare outcomes for women in two study arms that include retaining the cystoscopy distending fluid after minimally invasive hysterectomy verses completely emptying the cystoscopy distending fluid. The outcomes being measured for research purposes include the time spent to first spontaneous urination after surgery, rate of indwelling catheter insertion, length of recovery room stay, the amount of bladder discomfort immediately postoperative and over the first 24 hours postoperative, bladder symptoms over the first 24 hours postoperative, and patient satisfaction.

A prospective randomized control trial will be conducted at Good Samaritan Hospital and TriHealth Evendale Hospital. Subjects will receive total hip or knee surgery and follow-up via standard care at the discretion of the treating physician or the experimental study arm in which all patients will undergo the integrated care pathway.

This study aims to compare the incidence of urinary retention and requirement of bladder catheterization in patients undergoing total knee arthroplasty while receiving either continuous epidural analgesia or single shot femoral nerve block.

This study investigates patient's preference and satisfaction with choice of catheterization after surgical urogynecological procedures.
