    Notes: Abstract We evaluated our experience with buccal mucosa in urethral reconstruction for complex hypospadias repair in a total of 62 children operated on at our institution since 1990 at a mean follow-up of 23␣months. After the graft had been taken from the lower lip, with possible extension to the inner cheek, complete thinning of the graft was performed. The graft was then sutured in an onlay fashion to the urethral plate, and suprapubic urinary diversion was carried out for 3␣weeks. The overall complication rate in this rather complex series of patients, including 26 “hypospadias cripples,” was 13%; the complications involved 4 fistulas, 3 cases of graft necrosis, and only 1 meatal stenosis during the follow-up period. These favorable results prompted us to use buccal mucosa onlays as our current method of choice for urethral reconstruction with avoidance of tubularized repairs. The definite value of this technique, however, will become evident only after a longer follow-up period and confirmation of these favorable results.

    Notes: Abstract Computed tomography (CT) was performed in 28 patients 2 weeks to 120 months after enucleation of renal cell carcinoma. The postoperative defect could be exactly localized in all patients. A wedge-shaped (N = 11) or concave (N = 9) morphology was typical. No dependence between morphology of the defect and localization or size of the tumor or the operative technique was observed. The defects were smaller (1.9 cm) than the original prominent tumors (3.6 cm). Defect size was dependent on the operative technique: closure by suture of the renal capsule in smaller defects or by fat flap in larger ones. Postoperative hematomas or delayed perfusion in the adjacent parenchyma were seen in five patients. Tumor recurrence was correctly diagnosed in one patient.

    Description / Table of Contents: Summary The goal of this study was to investigate the practicability and effectiveness of a systematic screening for renal cell carcinoma by ultrasound in the course of the established German Health Ministry screening programs. Methods: In two centers (Mainz and Wuppertal) a screening program for renal cell carcinoma for all citizens (age 〉40 years) was established. The screening was divided into two phases (time period 1 year): (1) All citizens over 40 years could attend voluntarily a cost-free ultrasound investigation. (2) A follow-up investigation for the entire screening population was provided. Results: Ten thousand volunteers attended the screening program. Mean age was 60 years. Thirteen renal cell carcinomas were detected. The incidence of other findings was 15%; none of those required further treatment. Conclusion: Systematic screening for renal cell carcinoma by ultrasound is cost-effective and showed high acceptance and practicability in a German population. The rate of detection of renal cell carcinoma was higher than initially statistically calculated.
    Notes: Zusammenfassung Die zunehmende Zahl der zufällig mit der Ultraschalluntersuchung entdeckter, kleiner, asymptomatischer Nierenzellkarzinome, wirft die Frage der Praktikabilität und Effektivität einer systematisierten Screeninuntersuchung des Nierenzellkarzinoms mittels Sonographie auf. Vor diesem Hintergrund wurde eine Machbarkeitsstudie im Rahmen des Früherkennungsprogramms des Bundesministeriums für Gesundheit initiiert. Methodik: In 2 Städten, Mainz und Wuppertal, wurde ein Früherkennungsprogramm für das Nierenzellkarzinom etabliert, bei dem allen Einwohnern (Alter über 40 Jahre) eine kostenlose Ultraschalluntersuchung der Nieren angeboten wurde. Das Screening unterteilte sich in 2 Phasen (Laufzeit 1 Jahr): Erste Phase: kostenlose freiwillige Ultraschalluntersuchung, zweite Phase: Folgeuntersuchung der Screeningpopulation. Ergebnisse: Das angestrebte Ziel von 10.000 Teilnehmern wurde erreicht, das mittlere Alter lag bei 60 Jahren. 13 Nierentumore wurden entdeckt. Die Rate anderer, nicht therapiebedürftiger Nebenbefunde betrug 15%. Schlußfolgerung: Die Früherkennungsuntersuchung des Nierenzellkarzinoms mittels Ultraschall zeigte eine hohe Akzeptanz und Praktikabilität in beiden Städten, die Detektionsrate des Nierenzellkarzinoms war höher als initial am Boden der veröffentlichten Statistik kalkuliert.
