AIMS To investigate the feasibility of conditional short duration electrical stimulation of the penile/clitoral nerve as treatment for detrusor hyperreflexia, the present study was initiated. METHODS Ten patients with spinal cord injury, 4 women and 6 men, with lesions at different levels above the sacral micturition center had a standard cystometry(More)
OBJECTIVE The aim of our study of the pig was to investigate the responses of smooth muscle of the bladder and the urethral sphincter to preganglionic parasympathetic stimulation, and to assess the effect on the lower urinary tract of IV administration of alpha,beta-methylene-ATP. MATERIALS AND METHODS In seven anaesthetised female pigs, the responses to(More)
PURPOSE Routine use of ultrasound during pregnancy has emphasized the need for greater knowledge about normal and abnormal voiding function during fetal live. We describe the developmental changes in lower urinary tract function from the middle of the second to the early third trimester of gestation. MATERIALS AND METHODS The study included 22 male fetal(More)
The objective of this study was to evaluate the effect of automatic event-driven electrical stimulation on the dorsal penile/clitoral nerve for management of neurogenic detrusor overactivity in spinal cord injured subjects. In order to reach the objectives it was necessary to design and realize a portable device for ambulatory urodynamic studies which was(More)
This paper provides an overview of electrical stimulation of the nervous system as a treatment option for urodynamic dysfunction and of some of the recent results in this field. The set-up used in our studies for improved bladder filling in spinal cord injured patients by conditional stimulation of the dorsal penile/clitoral nerve is a highly efficient way(More)
UNLABELLED We investigated the effect of efferent stimulation of the pelvic (PN), hypogastric (HGN) and pudendal (PuN) nerves on ano-rectal motility in Göttingen minipigs using an impedance planimetry probe. Changes in the rectal cross-sectional area (CSA) at five axial positions and pressures in the rectum and anal canal were investigated simultaneously.(More)
AIMS Suprapontine neural integration during the storage phase is decisive for the timing of voiding. Neurological disorders like Parkinson's disease are thus frequently complicated by bladder dysfunction. The aim of the present study was to investigate the effect of high frequency deep brain stimulation on the urine storage and voiding function in conscious(More)
OBJECTIVE To apply stereotactic electrical stimulation of the pig brainstem and thus identify a pontine micturition centre. MATERIALS AND METHODS In 10 anaesthetized female Vietnamese minipigs a needle-electrode was positioned in the pontine region. Pressure responses in the lower urinary tract identified the micturition centre functionally during(More)
The porcine urological system is similar anatomically and physiologically to that of humans. Swine have a true multirenculate, multipapillate kidney with a calyceal system like that of humans. The gross anatomic and histologic characteristics of the porcine and the human kidney are more similar than most other commonly used laboratory animals. The(More)
Aiming at the development of an implantable neuroprosthesis for restoration of hand function in tetraplegic patients (C5/C6), we examined and compared the stimulation performance of two different neural electrode designs. Our studies on the radial nerve of adult pigs proved the feasibility of selective control of different forearm muscles by using only one(More)
