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 …

New coordination polymer based on a triply bridged dicarboxylate ligand: Synthesis, structure, and magnetic properties of the adipato complex [Cu4(bp…
2007
International audience; One-pot reaction of copper(II) chloride dihydrate CuCl2 · 2H2O with 2,2′-bipyridyl (bpy = C10H8N2) in the presence of sodium adipate Na2adip (adip2− = [O2C(CH2)4CO2]2−) and potassium 1,1,3,3-tetracyano-2-ethoxypropenide (tcnoet− = [(NC)2CC(OEt)C(CN)2]−) gives the new compound [Cu4(bpy)4(adip)3](tcnoet)2 · 2H2O (1), which was characterized by single crystal X-ray diffraction analysis. The Cu(II) metal ion presents an elongated square pyramidal CuN2O3 environment, with an oxygen atom in apical position and a base plane involving almost equivalent bond lengths. The structure can be described as a pseudo dinuclear species in which two Cu(bpy) units are triply bridged by …
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 …
Intracerebral Borna Disease Virus Infection of Bank Voles Leading to Peripheral Spread and Reverse Transcription of Viral RNA
2011
Bornaviruses, which chronically infect many species, can cause severe neurological diseases in some animal species; their association with human neuropsychiatric disorders is, however, debatable. The epidemiology of Borna disease virus (BDV), as for other members of the family Bornaviridae, is largely unknown, although evidence exists for a reservoir in small mammals, for example bank voles (Myodes glareolus). In addition to the current exogenous infections and despite the fact that bornaviruses have an RNA genome, bornavirus sequences integrated into the genomes of several vertebrates millions of years ago. Our hypothesis is that the bank vole, a common wild rodent species in traditional B…
Direct solution of compensated radial distribution networks with constant impedance/current loads
2009
In this paper, a methodology to solve radial distribution networks, with constant current and/or impedance loads as well as shunt capacitor banks, is proposed. The techniques currently available to solve such systems are based either on iterative methods or on the bus impedance matrix. In both cases, the elaboration times are quite high since these are related, for iterative methods, to the overall number of iterations, and, for those methods based on the impedance matrix, to the inversion of the admittance matrix. The method developed here is the extension of a technique that is valid to solve networks made of impedances with one supply point. The methodology can also be applied in the sol…
