Reliability of ambulatory urodynamics in patients with spinal cord injuries

To determine the test–retest repeatability of the urodynamic parameters commonly utilized in ambulatory urodynamics (AM) for patients with neurogenic lower urinary tract dysfunction (NLUTD).

A Study on the Viscoelastic Properties of the Urinary Bladder in Dogs

This experimental study was designed and carried out in order to investigate the participation of the collagen and muscular tissues on the viscoelastic properties of the bladder wall. Sixty-five adult male mongrel dogs were utilized. These animals were divided into 5 groups: control group (n = 10); dogs (n = 10) receiving 2.5 mg/kg atropine (cholinergic antagonist); dogs (n = 10) receiving 0.7 mg/kg verapamil (calcium extracellular inflow blocker); dogs (n = 10) receiving 0.1 mg/kg/min nitroprusside (intracellular calcium blocker), and dogs (n = 25) receiving EGTA (a calcium-chelating agent) at increasing doses from 90 to 450 mg/kg. Based on a mathematical model, we have demonstrated that: (1) the collagen component is responsible for the elastic properties; (2) the muscle component is responsible for the viscoelastic properties; (3) the viscoelastic properties have an active element which is affected by calcium total depletion, and (4) such viscoelastic properties are not dependent on cholinergic stimulation.

“Overactive bladder”: Main urinary symptoms and urodynamic patterns in the elderly

Overactive bladder is the most frequent type of urinary incontinence in the elderly; its main symptoms are frequency, urgency and urge-incontinence. The diagnosis is based on urodynamic testing; however, a few years ago Abrams and Wein proposed a new clinical approach to overactive bladder. Aims: The main aims of this study were: firstly to determine the prevalence of overactive bladder in elderly patients with established urinary incontinence; secondly, to describe the main clinical features of this condition; and finally to describe its urodynamic patterns. Methods: A retrospective study of the medical records and urodynamic data of 682 older patients with urinary incontinence who underwent urodynamic testing. Results: The sample included 682 patients (350 men, and 332 women), with a mean age of 73.24 years. The most frequent symptoms were: frequency; urge-incontinence and incontinence at cough. Mixed types of overactive bladder were more common than isolated overactive bladder; bladder outlet obstruction was associated chiefly with overactive bladder. A postvoiding residual urine over >100 ml was found in 136 patients (20 of the entire sample). In this subgroup, the urinary symptoms were similar to those of the rest of the sample. Conclusion: Our results suggest that the urodynamic study is very useful in identifying the type of urinary incontinence.

Turn-amplitude analysis as a diagnostic test for myofascial syndrome in patients with chronic pelvic pain.

Myofascial pain syndrome of the pelvic floor is a common cause of chronic pelvic pain. The etiology of this neuromuscular pain disorder is unknown and symptoms can vary widely. Research attempting to identify an appropriate diagnostic test has, to date, not been fruitful. This study aimed to investigate the utility of turns-amplitude analysis, which involves analyzing electromyography data of the levator ani and anal sphincter muscles, as a diagnostic tool.

Endoscopic treatment of vesicoureteral reflux with non-simultaneous involuntary detrusor contraction in chronic spinal cord injury patients with neurogenic detrusor overactivity.

Objective: To analyze whether it is correct to use endoscopic treatment via bulking agents of vesicoureteral reflux (VUR) seen on video urodynamics with non-simultaneous involuntary detrusor contraction in chronic spinal cord injury (SCI) patients with neurogenic detrusor overactivity (NDO). Methods: A retrospective study was performed with a cohort of 76 patients (age 48.9 ± 14.4 years) (mean ± standard deviation) of both sexes with chronic SCI who underwent endoscopic treatment of VUR during the years 2008 to 2011. Patients were subjected to clinical examinations and video urodynamic studies preoperatively and 22 ± 11.4 months after the intervention. Results: Resolution of VUR was achieved in 46 cases (61%). Cured patients had a statistically significant younger age and showed stress urinary incontinence more frequently. On the contrary, a greater grade of VUR, presence of bilateral reflux and presence of NDO were positively associated with treatment failure. The variables that independently influenced the cure of the reflux were NDO and reflux grade. Conclusions: The failure rate was high in patients with NDO, even though the reflux was not synchronous with involuntary detrusor contraction, and therefore these patients should have NDO eradicated before doing any anti-reflux procedures.
