    Notes: Abstract We report the case of a 44-year-old male presenting with deviation of the penis during erection. Upon physical and clinical examination the patient did not have the typical findings of Peyronie's disease, therefore he was admitted for further evaluation by conventional sonography, duplex Doppler ultrasound, endourethral ultrasound and magnetic resonance imaging (MRI). Endourethral ultrasound and MRI provided evidence of Peyronie's disease with atypical involvement of the corpus spongiosum and, in addition, demonstrated nonpalpable plaques in the septum of the penis.

    Notes: Abstract In order to identify a high-risk group for the development of arterial hypertension after extracorporeal shock wave nephrolithotripsy (ESWL), we correlated the increase in renovascular resistance induced by ESWL in 79 normotensive patients with changes in arterial blood pressure occurring 20 (+-3) months after therapy. Renal vascular resistance was measured as resistive index (RI) by duplex Doppler sonography in both kidneys. Mean RI before treatment was 0.620±0.035 (SD). After treatment, we observed a significant and age-dependent increase in the RI in the treated kidney to 0.673 ± 0.06. Of the patients with a post-ESWL RI〉 0.690, 39% developed hypertension. Posttherapy RI values surpassing 0.690 showed a 0.8 sensitivity and a 0.7 specificity in predicting arterial hypertension. Intrarenal Doppler ultrasound (US) is useful to find the high-risk group for arterial hypertension after ESWL.

    Notes: Abstract. The aim of our study was to evaluate the striated urethral sphincter (rhabdosphincter) in incontinent females by means of intraurethral ultrasound (IUUS). Thirty-four incontinent and 11 continent female patients were examined by means of 12.5-MHz endoluminal ultrasound (US). The distance between the inner contour of the sphincter muscle and the US catheter was measured in the contracted and the non-contracted condition. The US findings were correlated with those obtained by urodynamic studies. Partial or complete loss of sphincter function was detected in patients with stress urinary incontinence (SUI). Reduced sphincter function was not observed in patients with urge incontinence and continent volunteers. The findings on US were found to correlate well with the grade of SUI. The IUUS technique offers the benefit of direct visualization of the sphincter mechanism. Therefore, endoluminal US may become an important adjunct in the diagnostic evaluation of SUI and will possibly provide new insights for a better therapeutic strategy.

    Description / Table of Contents: Summary Sonography of the shoulder joint is a well-established technique in the hands of the experienced examiner, when using a standardized protocol. It has proved invaluable in assessing pathological soft tissue changes, especially after trauma. The static evaluation of anatomy and dynamic assessment of function are especially helpful in both preoperative staging and postoperative follow-up. The normal anatomy, examination techniques, including our own variations, and pathological conditions are discussed. The findings and various classifications of impingement syndrome, rotator cuff injuries, biceps tendon lesions and inflammatory changes are examined. Review of the major articles in the literature shows excellent correlation with our results, the overall sensitivity in the case of rotator cuff lesions being over 90 %. A well-performed ultrasound examination in most cases obviates the need for the more invasive arthroscopy and the more cumbersome and expensive MRI examinations.
    Notes: Zusammenfassung Der Stellenwert der Schultersonographie unter standardisierten Untersuchungsbedingungen und entsprechender Erfahrung des Untersuchers ist unbestritten. Insbesondere im Bereich der Traumatologie ist die Wertigkeit bei Rotatorenmanschettenläsionen mit entsprechendem operativem Korrelat statistisch gut abgesichert. Die Overall-Sensitivität bei Rotatorenläsion liegt heute bei ca. 95 %. Partielle und Totalrupturen der Rotatorenmanschette sowie das Impingementsyndrom fallen unter den Sammelbegriff Subakromialsyndrome und sind sonographisch sowohl in statistischer als auch dynamischer Untersuchungstechnik gut beurteilbar. Eine wesentliche Bedeutung hat die sonographische Normalwertbestimmung von Schulterweichteilen als metrisches Fundament zur Bewertung pathologischer Veränderungen. Ein definiertes Staging (prä- wie postoperativ) ermöglicht eine exakte Operationsplanung sowie eine genaue Therapiekontrolle. Die Beurteilung der Gleitlager als indirekter Hinweis auf Traumen bzw. bei entsprechender Klinik als Anhaltspunkt entzündlicher Veränderungen mit exsudativ proliferativen Gelenkergüssen oder im Rahmen der Tendinitis calcarea ist heute sonographischer Untersuchungsstandard. Die Indikation für andere Untersuchungsverfahren wie Arthroskopie, Kontrast-CT oder MRT ist dadurch zurückgedrängt.
