A new presentation technique is introduced 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 qualitative models which are derived from the literature. Opinions concerning the reflex arcs and supraspinal connections said to be involved in micturition and continence are different and sometimes contradictory… 

Mathematical modelling of the lower urinary tract

Reflexes or Controller Action

The pelvic autonomic ganglia are treated in this chapter together with cross-sensitization: the neuronal influence of pelvic separate parts on each other.

Innervation of the Mature Human Pelvis

The basic connections of pelvic organs are described in this chapter and it is shown that the peripheral nervous system makes it possible to treat autonomic–somatic interactions but also neuromodulation and dorsal rhizotomy.

A Conductance-Based Sensor to Estimate Bladder Volume in Felines

Benchtop evaluation of the design, prototyping and validation of a sensing mechanism for a catheter-free fluid volume estimating system for chronic neurophysiological studies of the lower urinary tract and ambulatory urodynamics indicates that conductance-based volume sensing of the urinary bladder is a feasible method for real-time measurement.

Electrical stimulation for the treatment of bladder dysfunction: Current status and future possibilities

This article first reviews the history of electrical stimulation applied for treatment of bladder dysfunction and then focuses on the implantable Finetech-Brindley stimulator to produce bladder emptying, and on external and implantable neuromodulation systems for Treatment of incontinence.

Simulation of the Neuronal Regulator of the Lower Urinary Tract Using a Multiagent System

A tool has been implemented which allows to simulate the functioning of the model showing the values related to urodymanic variables graphically and the results have been validated by comparing them with real data.

A Multi-Agent System uses Artificial Neural Networks to Model the Biological Regulation of the Lower Urinary Tract

The model is robust and it satisfies the expectations of providing a model of the regulator system that allows to break into fragments the problem, in simple modules with own entity each.

The Functions of Efferent Nerves to the Lower Urinary Tract

The starting point of this chapter will deal with an effect which appears to be mediated by parasympathetic efferent neurons within the central part of their course, viz. the phenomenon of recurrent inhibition.

Reflex Control of the Lower Urinary Tract

Reflexes that regulate the lower urinary tract may have pathways entirely within the spinal cord or may involve looped pathways coursing between the cord and the brainstem. The ascending pathways

Bladder Control: Role of Higher Levels of the Central Nervous System

The results suggest that control over the bladder and sphincters is organized in different areas of the cortex and at various levels of the nervous system, the lowest of which is the spinal cord.

Control and coordination of bladder and urethral function in the brainstem of the cat

Stimulation and lesion experiments in the pontine tegmentum of 34 cats have confirmed the existence of two different brainstem regions concerned with lower urinary tract function, and suggest that the M region forms a true micturition centre, facilitating the detrusor voiding contraction and also ensuring synergic sphincter relaxation.

Anatomical, neuromorphological and physiopharmacological studies on the musculature of the organs of micturition, especially in the past two decades, have suggested the following concepts of its

Visceral sensations are often vague, and sensations arising from the lower urinary tract are no exception, with the result that a surprisingly large number of sensations associated with micturition
