Background It is suggested that the body posture during urination can influence urodynamic parameters in patients with Lower Urinary Tract Symptoms (LUTS) to an extent approaching pharmacological interventions. In this article, the influence of body position during micturition on…
This article summarizes anatomical, neurophysiological, pharmacological, and brain imaging studies in humans and animals that have provided insights into the neural circuitry and neurotransmitter mechanisms controlling the lower urinary tract. The functions of the lower urinary t…
Indiscriminate voiding of excreta by cattle contributes to greenhouse gas (GHG) emissions and soil and water contamination<sup>1</sup><sup>,</sup><sup>2</sup>. Emissions are higher in animal-friendly husbandry offering cattle more space<sup>2</sup> - a trade-off we call the 'clim…
Mammalian Olfaction, Reproductive Processes, and Behavior presents the conceptual, methodological, and empirical advances in the study of the complex interactions between nasal chemoreception, sexual behavior, and endocrine function in mammals. It focuses on the orders Artiodacty…
Approximately 60% of Japanese men void in the sitting position at home. There are certain differences in the associations of LUTS and health conditions with voiding position by age, while seated voiding is consistently associated with marital status throughout all ages, which imp…
We illustrate the importance of good technique when using a urinal and offer some advice. Through high-speed video footage of a simulated male urine stream ...
For healthy men, no difference is found in any of the urodynamic parameters. In patients with LUTS, the sitting position is linked with an improved urodynamic profile.
A new presentation technique is introduce to describe the neuronal circuitry involved in the control of the uropoëtic system and its control mechanisms during the micturition cycle. This method is based on the preparation of flow charts and is applied to the discussion of four qu…
Some of the most recent work investigating the cerebral mechanisms involved in bladder control has been very helpful in adding to our understanding of bladder dysfunction. The group behind this work, from London, presents a mini-review which will help to update our knowledge in t…
These results indicate that in the anesthetized rat activation of urethral afferents by urethral perfusion can modulate the micturition reflex. Thus in patients with stress urinary incontinence, leakage of urine into the proximal urethra may stimulate urethral afferents and facil…
During micturition, according to the concept of Blok, Holstege, and colleagues ([1997] Neurosci. Lett. 233:109-112), the pontine micturition center (PMC) elicits bladder contraction by way of direct excitation of the parasympathetic bladder motoneurons. At the same time, the PMC…
Micturition is a spino-bulbo-spinal reflex. The bulbospinal part of this reflex is formed by the projections from the M-region, also called the pontine micturition center or Barrington's nucleus, to the preganglionic parasympathetic motoneurons in the sacral cord innervating the…
1. Reflexes to sacral parasympathetic neurones were studied by electrophysiological techniques in decerebrate, in chloralose-anaesthetized, and in chronic spinal cats.2. Excitatory reflexes from pelvic nerve and sacral somatic afferent nerve fibres were present before and after c…
We have investigated with light and electron microscope immunocytochemistry the aminergic and peptidergic innervation of Onuf's nucleus in adult baboons. This nucleus, located in the ventrolateral part of the sacral spinal cord (S2 and S3), is considered to control urethral and a…
