    Notizen: Abstract In a retrospective study 108 patients (average age: 56.5 years) could be evaluated, who were treated with a fascial sling plasty because of pure genuine stress incontinence (n=90) or combined stress/urge incontinence (n=18). 72 patients (66.6%) had recurrent incontinence after previous surgery. The average follow-up was 5 years. Patients without previous surgery related to urinary incontinence (n=36) showed the best results and remained continent in 78% (n=28). Patients with 1 to 4 (average 1.4) previous surgical procedures because of incontinence (n=52) remained continent in 62% (n=32), and in those who had between 1 and 6 (average 3.6) previous surgical procedures using even alloplastic material the continence rate dropped to 60% (n=12). In patients with pure genuine stress incontinence the overall success rate was 74.7%, whereas in cases with a proven preoperative urge component, the success rate dropped to 37%. Fascial sling plasty is a very useful procedure to treat patients with primary and especially recurrent urinary incontinence, when a functional urethra is missing. However, one has to be very cautious with patients in whom a preoperative urodynamic evaluation shows detrusor instability.

    Beschreibung / Inhaltsverzeichnis: Summary The International Consensus Committee recommends α-adrenoceptor antagonists for medical therapy of benign prostatic hyperplasia (BPH). This review evaluates 52 randomized, placebo-controlled, double-blind studies, including 10 399 patients and, moreover, 40 clinical studies including 33 600 patients undergoing treatment with α-adrenoceptor antagonists because of BPH. The therapeutic efficacy of all α-adrenoceptor antagonists is more or less the same. There is an average improvement of symptom scores of about 35 % and a mean increase in maximum flow rate of between 1.8 and 2.5 ml/s. Studies investigating long-term efficacy and quality of life tend to show a long-term benefit. The introduction of selective α1-adrenoceptor antagonists led to a significant reduction of side effects. These side effects are primarily caused by the vasodilatatory qualities of α-blockers. The development of so-called uroselective α1A-adrenoceptor antagonists in the treatment of BPH possibly leads to further reduction of side effects related to vasodilatation. Medical therapy by α1-adrenoceptor antagonists seems to be superior to phytotherapy or treatment with 5α-reductase inhibitors, as shown in a few studies. So far, it is not clear whether there is any advantage of combination therapy. The application of α1-adrenoceptor antagonists is indicated in all cases of symptomatic BPH, excluding patients who need TUR-P (e. g., middle lobe) or prostatectomy. If patients are either willing or eligible to have surgical treatment, therapy by α1-adrenoceptor antagonists is a rational choice. Comparative clinical trials have to be conducted to provide additional information and to clarify which α-blocker may be recommended as the first choice. Until then, those α1-adrenoceptor antagonists should be used for which safety and efficacy are well documented and which can be prescribed at reasonable costs.
    Notizen: Zusammenfassung Das Internationale Konsensuskomitee empfiehlt α-Adrenozeptorantagonisten zur medikamentösen Therapie der benignen Prostatahyperplasie (BPH). In dieser Übersicht werden 52 randomisierte, plazebokontrollierte, doppelblinde Studien mit 10 399 Patienten sowie 40 weitere klinische Studien mit über 33 600 Patienten, die wegen einer BPH mit α-Adrenozeptorantagonisten behandelt wurden, zusammengestellt. Dabei zeigt sich, daß die therapeutische Effektivität sämtlicher α-Adrenozeptorantagonisten im wesentlichen gleich ist. Im Durchschnitt wird eine Verbesserung der Symptomenscores um 35 % beobachtet. Der mittlere Anstieg der maximalen Harnflußrate liegt zwischen 1,8 und 2,5 ml/s. Untersuchungen zur Langzeiteffektivität und Lebensqualität deuten auf andauernde Verbesserungen hin. Durch die Einführung selektiver α1-Adrenozeptorantagonisten konnte eine deutliche Verminderung der Nebenwirkungen dieser Substanzen erzielt werden. Diese Nebenwirkungen sind in erster Linie durch die blutdrucksenkenden Eigenschaften der α-Blocker bedingt. Die Etablierung sog. uroselektiver α1A-Adrenozeptorantagonisten in die Behandlung der BPH führt möglicherweise zu einer weiteren Reduktion durch Blutdrucksenkung bedingter unerwünschter Eigenschaften. Bis zur Klärung des Stellenwertes der verschiedenen Medikamente in prospektiven vergleichenden Studien, sollten solche α1-Adrenozeptorantagonisten Verwendung finden, die kostengünstig sind und sich als sicher und effektiv erwiesen haben.

    Notizen: Abstract Because of their resistance to fragmentation, treatment of brushite stones is a big problem. This study was performed to look for an improvement in therapeutic strategies by using artificial stones made of brushite (Bon(n)-stones), which are comparable to their natural counterparts. Using an ultrasound transmission technique, longitudinal wave propagation speeds were measured at different time intervals during treatment with hemiacidrin. From these and density measurements, transverse wave speed, wave impedance and dynamic mechanical properties of the artificial stones were calculated. Moreover, the microhardness of artificial stones was measured and investigations on shock wave lithotripsy (SWL) combined with initial chemolytic treatment of the stones were performed. The suggestion was confirmed that stone fragility and thus SWL can be improved by varying the physical properties of brushite stones through treatment with hemiacidrin. Additionally, we demonstrated the efficacy of Suby G in dissolving artificial brushite stones using an experimental arrangement simulating the physiological conditions in the upper urinary tract. Moreover, the efficacy of four different intracorporeal lithotripsy devices (electrohydraulic, pneumatic, laser and ultrasound) was tested and it was shown that electrohydraulic lithotripsy seems to be the best system for comminution of brushite stones.

    Notizen: Abstract  Spreading depression (SD) of electroencephalographic activity is a dynamic wave phenomenon in the central nervous system (CNS). The retina, especially the isolated chicken retina, is an excellent constituent of the CNS in which to observe the dynamic behavior of the SD wave fronts, because it changes its optical properties during a SD attack. The waves become visible as milky fronts on a black background. It is still controversial what the basic mechanistic steps of SD are, but certainly SD belongs to the self-organization phenomena occurring in neuronal tissue. In this work, spiral-shaped wave fronts are analyzed using digital video imaging techniques. We report how the inner end of the wave front, the spiral tip, breaks away repeatedly. This separation process is associated with a Z-shaped trajectory (extension ∼1.2 mm) that is described by the tip over one spiral revolution (period 2.45±0.1 min). The Z-shaped trajectory does not remain fixed, but performs a complex motion across the retina with each period. This is the first time, to our knowledge, that established imaging methods have been applied to the study of the two-dimensional features of SD wave propagation and to obtaining quantitative data of their dynamics. Since these methods do not interfere with the tissue, it is possible to observe the intrinsic properties of the phenomenon without any external influence.
