Selective Sacral Nerve Blockade for the Treatment of Unstable Bladders
1987
38 patients with severe urge or urge incontinence, who did not respond to conservative therapy, were treated with selective sacral nerve blockade using a local anesthetic (bupivacaine). 6 patients of this group had definite selective sacral denervation with phenol. In 31 patients a urodynamic study was done previous to the sacral nerve block as well as 10 and 90 min after the injection. Within the first 2-7 weeks the success rate was about 70% in regard to bladder capacity and mean volume at first desire to void. On long-term follow-up (greater than 7 months), the success rate decreased to about 16%. Only 1 patient of the phenol group still has complete detrusor areflexia for now more than …
Limitaciones de paso durante la celebración de batidas
2014
El artículo analiza la posibilidad de que durante la realización de una cacería de animales de caza mayor los organizadores puedan solicitar a la Administración competente las limitaciones y prohibiciones de paso en caminos y sendas públicas para terceras personas ajenas a la cacería. Además se justifica dichas limitaciones como el resto de limitaciones que se establecen por otras actividades sociales en la que tambien se producen limitaciones de paso en orden a las cargas de la vida en común (carreras, procesiones, fiestas populares, etc.)
Ultrasound measurement of detrusor thickness in bladder instability in women
1997
– Ultrasound was used to measure the detrusor thickness in 20 women with urodynamically-proved detrusorial instability. In 95% of the cases, detrusor thickness is greater than or equal to 5 mm. Comparison with a control group confirms the reliability of these results.
Mechanical and electrophysiological effects of cromakalim on the human urinary bladder.
1994
The effects of cromakalim on spontaneous and induced mechanical activity of human detrusor muscle were investigated in vitro. Cromakalim produces a concentration-related decrease of spontaneous as well as carbachol- and K(+)-evoked contractions. This is the first study to utilize the patch clamp technique to elucidate the mechanism of action of cromakalim on human detrusor cells. Cromakalim hyperpolarizes the detrusor cells by increasing the net outward current which is most likely carried by potassium ions. In the human urinary bladder, this effect is mediated by a glibenclamide-sensitive potassium channel, as glibenclamide is able to diminish the relaxant effect of cromakalim and to preve…
Late results of bladder stimulation in 11 patients: followup to 4 years.
1978
Abstract Direct stimulation of the detrusor muscle offers the best possibility to evacuate the bladder in highly selected patients. During the last 4 years 11 patients have undergone implantation of a bladder pacemaker. Followup revealed that 1 patient could void only during stimulation, while 7 patients had reflex evacuation and 3 had no function at all. An exceptional case report is presented.
Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients
2021
Item does not contain fulltext Introduction and objectives: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors th…
MODULATION OF BLADDER α1-ADRENERGIC RECEPTOR SUBTYPE EXPRESSION BY BLADDER OUTLET OBSTRUCTION
2002
Purpose: α1-Adrenergic receptor (α1AR) antagonists are effective for relieving obstructive and irritative symptoms in patients with bladder outlet obstruction. While the α1aAR is responsible for prostate smooth muscle relaxation and outlet obstruction relief, to our knowledge the mechanisms underlying the relief of irritative symptoms remain to be determined. Therefore, we investigated mechanisms by which bladder α1AR subtypes may be involved in this process.Materials and Methods: We studied 42 rats, including 6 unoperated controls, 17 sham operated controls and 19 obstructed animals. Animals were characterized for baseline voiding pattern, followed by surgical intervention or sham surgery …
Chirurgische Anatomie und neurophysiologische Parameter zur intraoperativen Identifikation und Funktionsprüfung autonomer Beckennerven bei TME wegen …
2003
Introduction The identification and preservation of parasympathetic and sympathetic pelvic nerves is required to avoid urogenital malfunctions after TME for rectal carcinoma. The objective was to determine the surgical topography of the nerves with regard to TME. Neurophysiologiecl parameters for the intraoperative stimulation of the detrusor muscle were assessed in order to establish a functional test for the intraoperative identification of the pelvic autonomic nerves.
High-pressure powder x-ray diffraction study of EuVO4
2015
The high-pressure structural behavior of europium orthovanadate has been studied using in-situ, synchrotron based, high-pressure x-ray powder diffraction technique. Angle-dispersive x-ray diffraction measurements were carried out at room temperature up to 34.7 GPa using a diamond-anvil cell, extending the pressure range reported in previous experiments. We confirmed the occurrence of zircon-scheelite phase transition at 6.8 GPa and the coexistence of low- and high-pressure phases up to 10.1 GPa. In addition, clear evidence of a scheelite-fregusonite transition is found at 23.4 GPa. The fergusonite structure remains stable up to 34.7 GPa, the highest pressure reached in the present measureme…
Efficiency range of the Belousov-Zhabotinsky reaction to induce the self-organization of transient bonds in metallo-supramolecular polymeric systems.
2020
The periodic change of the oxidation state of the metal catalyst in the oscillating Belousov-Zhabotinsky (BZ) reaction has been reported to establish a periodic organization of metallo-supramolecular bonds in polymeric systems, which results in autonomous viscosity oscillations. To appraise the possible extent of quantitative control on the viscosity oscillation features, we assess how the kinetics of the BZ reaction affects the periodic self-organization of the metal-ligand coordination, and vice versa. Our model system includes mono-, bis-, and tetra-functional polyethyleneglycol (PEG) precursors end grafted with terpyridine ligands that are complexed with ruthenium ions, which oscillate …
