Contraction of ureteral smooth muscle drives the urine bolus to the urinary bladder for storage prior to micturition. This study describes a novel approach to the measurement of ureteral pressure generation in vitro and the influence of distending pressure on acetylcholine-stimulated ureteral lumenal pressure generation. Isolated segments of ureters obtained ...

In vivo animal cystometry represents an accepted methodology for the study of lower urinary tract physiology. A particular advantage of the mouse model is the availability of genetically modified strains, offering the possibility of linking individual genes to relevant physiological events. However, small voided volumes complicate the ability to obtain ...

In multiple system atrophy (MSA), parkinsonism and a cerebellar syndrome are associated with autonomic dysfunction. Both bladder neck dysfunction and external sphincter denervation have been implicated in detrusor-sphincter dyssynergia. However, urethral dysfunction may not be adequately reflected by a single global measurement of urethral pressure. Pressure assessment at several levels ...

The need for an indwelling transurethral catheter in patients with postoperative thoracic epidural analgesia (TEA) is a matter of controversy. Subjective observations are ambivalent and the literature addressing this issue is scarce. As segmental blockade can be achieved with epidural analgesia, we hypothesized that analgesia within segments T4-T11 has no ...

Previous studies have reported immunoreactive opioid nerve fibers in the detrusor and lower urinary tract sphincters. However, there is a paucity of in vivo studies demonstrating the direct effect of endogenous opioids in these structures. In the present study, we investigated the contractile actions of intra-arterially administered exogenous Dynorphin-A, Met-enkephalin, ...

Troublesome voiding lower urinary tract symptoms (LUTS) are a common problem in men, particularly with ageing. Implicitly, management of voiding LUTS can be guided by accurate determination of underlying mechanisms, distinguishing men with voiding symptoms caused by outlet obstruction from those with reduced bladder contractility. A PubMed search of the ...

Whether urinary incontinence in the postmenopause can be prevented or delayed by estrogens is currently controversially debated. Ovariectomized (ovx) rats have been successfully used as models in the past years but plant derived substances with estrogenic effects in the lower urinary tract have not been studied so far. Therefore we ...

OBJECTIVES: To test the hypotheses that: (i) significant differences should exist in pressure/flow data between radiologically determined bladder neck and prostatic obstruction; (ii) these differences should inform understanding of the pathophysiology of male outflow obstruction. The biomechanics of the voiding/pressure/flow plot imply that a urodynamic assessment trace should identify outflow ...

The measurement of the rectal pressure is considered to be the 'gold standard' for the assessment of the abdominal pressure. However, conventional rectal catheters can cause erroneous results and are not comfortable for the patients. To reduce these problems, we devised a non-invasive technique for the measurement of the abdominal ...
