OAB Evidence from the Urologist’s Perspective

2003

Abstract Overactive bladder (OAB) is the term introduced by the International Continence Society in 2002 to describe the symptoms of urgency, with or without urge incontinence, usually in the presence of frequency and nocturia. Community-based prevalence studies have shown an estimated 16% of the adult population in the US and Europe suffers the symptoms of OAB, and in many cases the symptoms can have a profound effect on quality of life. OAB can also co-exist with other disorders (e.g. depression, sleep deprivation, urinary tract and skin infections) which further increases the burden to the patient. Contemporary therapeutic algorithms, based on clinical experiences and evaluations of the …

Variations PSA Value in Patients Candidate to Biopsy of the Prostate

2005

Subclinical infections of the prostate can increase the prostate-specific antigen (PSA) values in patients with normal digital rectal examination. This study aimed to evaluate the role of short-term antimicrobial therapy in reducing the PSA value in patients as candidates for transrectal biopsy. Fifty-eight patients with negative digital rectal examination and PSA values between 4 and 20 ng/mL were included in the study. Antibiotics were administered to all patients for 3 weeks, and the PSA was reassessed 10 days after the end of the treatment. Patients were subsequently submitted to prostate biopsy. A reduction in PSA was detected in 34 patients (59%). Mean percentage reduction was 32%. I…

99mTc–MAG3–Nierenfunktionsszintigraphie ohne und mit Captopril zur Diagnostik der renovaskulären Hypertonie

1993

In this study, the diagnostic value of renal function scintigraphy performed both without and with ACE inhibition has been evaluated using the new radiopharmaceutical 99mTc-MAG3. In cases of decompensated renal artery stenoses, the typical scan finding with this tubular excreted agent was shown to be a distinct parenchymal nuclide retention in combination with a delayed appearance of the radiotracer in the pelvic system. Using this criterion in 43 patients with suspected renovascular hypertension, sensitivity and specificity were 89 and 88%, respectively. Bilateral positive findings were non-specific; excluding them from the study, specificity increased to 100%. In renal insufficiency, capt…

Confocal Laser Endomicroscopy and Chromoendoscopy - A New Option of Surveillance in Patients with Ureterosigmoidostomy or Rectosigmoid Pouch

2010

Purpose In patients with bladder exstrophy-epispadias-complex (BEEC) or in selected patients with bladder loss for other reasons, ureterosigmoidostomy (USIG) & rectosigmoid pouch (Mainz Pouch (MZP) II) has been used at our institution. This diversion carries a lifelong risk for secondary malignancies. Therefore annual colonoscopy is recommended. Identification of potentially malignant structures can be challenging, and biopsies are taken in doubt, with the risk of injuring the ureterocolic implantation site. Using confocal laser endomicroscopy (CLE) and chromoendoscopy, the uretero-intestinal anastomosis is better visualized compared to conventional colonoscopy, and target biopsies could be…

Interdisciplinary management of peripheral arteriovenous malformations: review of the literature and current proceedings.

2021

Arteriovenous malformations (AVMs) are a rare congenital vascular disorder. They represent a fast-flow vascular malformation. Clinically, AVMs present a heterogenous expression and can affect every part of the body. Here, we will solely focus on extracranial AVMs. Generally, AVMs progress with the patient's age. Patients often suffer from pulsation, skin discoloration, pain, ulceration, bleeding, and disfigurement. Diagnostic tools include color-coded duplex sonography, MRI and CT imaging, as well as the clinical examination. 4D dynamic perfusion-computed tomography may help in the interventional planning. Digital subtraction angiography is required during interventional therapy. AVMs pose …

Das Pulmonalarteriensarkom - Prä- und postoperative radiologische Befunde bei der Tumorerstmanifestation und beim Rezidiv

2008

Purpose Primary pulmonary artery sarcomas are very rare tumors. Their diagnosis is difficult due to their unspecific symptoms. Still, an early preoperative diagnosis is the only possibility for a potential therapy. Patients and methods 4 pre- and 5 postoperative CT- and three pre- and one postoperative MRT-examination(s) have been evaluated with respect to surgical and histological findings. Results The presence of a convex intraluminal bulging mass spreading mostly from the pulmonary trunc continuously into the peripheral pulmonary artery branches the filling and dilatation of the vessels, the tumor's inhomogeneity indicating hemorrhages and necrosis and the appearance of intrapulmonary no…

CT-Angiographie bei arterieller Verschlußkrankheit: Vergleich von 3 Rekonstruktionsverfahren

1997

Purpose To evaluate different rendering techniques of CT data for the assessment of long vessel segments in peripheral vascular occlusive disease. Material and methods 40 CT angiograms (aortoiliac: n = 20, leg arteries: n = 20) were viewed using three different rendering techniques: 1, maximum intensity projection (MIP); 2, volume rendering (VR); 3, shaded surface display (SSD). CT angiograms were obtained in 6 or 8 projections. Axial cross-section images were analysed using an interactive cine mode. Intraarterial DSA was the standard in all cases. Results The sensitivities for the diagnosis of occlusive disease were 100% (cross-section images), 94% (MIP), 91% (VR) and 93% (SSD). The specif…

Kontrastverstärkte dreidimensionale MR-Angiographie der A. carotis bei 1,0 Tesla im Vergleich zuri.a. DSA - ist die Methode für die Diagnostik von Ka…

2001

Artery Disease? Purpose: To evaluate the efficacy of three-dimensional, contrast-enhanced magnetic resonance angiography (CE-MRA) of the carotid artery with a 1.0 system in comparison to intra-arterial conventional angiography (i.a.CA) for the assessment of carotid artery disease. Method: 55 patients with suspected stenosis of the carotid artery were examined with a 3D-CE gradient-echo sequence on a 1.0 T scanner (TR/TE = 6.2/2.2 ms) and a selective DSA i.a. angiography. Image quality was evaluated by estimating the arterial contrast and venous enhancement. Morphological pathologies were registered for all arteries, stenoses of the internal carotid artery were graded by applying the NASCET …

ICD Implantation in Noncompaction of the Left Ventricular Myocardium: A Case Report

2009

Isolated noncompaction of the ventricular myocardium (INVM) is an uncommon cardiomyopathy characterized by the persistence of fetal myocardium with prominent trabecular meshwork and deep intertrabecular recesses, often associated with systolic dysfunction and ventricular dilatation. A 23-year-old man from Burkina Faso was referred to our operative unit with a diagnosis of INVM, made with echocardiogram and magnetic resonance imaging and nonsustained ventricular tachycardia. The literature reports the incidence of malignant ventricular arrhythmias in as many as 47% of the patients and sudden cardiac death in almost 50% of them and this supported our decision to perform implantable cardiovert…
