[Congenital urogenital malformations associated with nephroblastomas. Long-term results of a study in Erlangen].

Background: Wilms' tumors are highly malignant tumors of the kidneys and are among the most frequent solid tumors of childhood, which are diagnosed for the most part before the 5th year. Various congenital anomalies are associated with a genetic predisposition and thus an increased risk of developing a Wilms' tumor.

Patients And Methods: As part of a retrospective analysis, the records from 1965 to 2003 of 66 patients with histologically confirmed Wilms' tumor were reviewed.

[Wilms' tumors in adults].

Wilms' tumors develop from persistent, primitive metanephrogenic stem cells. Their biology and etiology in adults is still unknown even though remnants of primitive metanephrogenic tissue, which tends to malignancy, is suspected, and there are very few scientific studies on the biology of Wilms' tumors in adults. Such a tumor occurs at a rate of 0.

[Risk factors for intra- and postoperative complications in Wilms' tumor surgery].

Background: Wilms' tumor is the most common renal tumor in childhood. Preoperative treatment is still under discussion. The aim of this study was to determine, using our own patient collective, the risk factors for and type of intraoperative complications which can occur.

[Endometriosis of the ureter and urinary bladder].

Endometriosis is a benign growth of ectopic endometrial mucous membrane which has maintained the histological characteristics and biological reactions of uterine mucous membrane. In only 1-2% of cases does it occur in the urinary system, most commonly in the urinary bladder. Such an endometriosis is often diagnosed very late due both to its commonly asymptomatic course and its rarity.

[Impact factors and publication time spans in urological journals].

The impact factor, cited half-life, and immediacy index are three important methods that can be used to demonstrate how a journal's articles are cited over the course of a specific time span. These three factors thus represent instruments for measuring the importance and reputation of a scientific magazine. The goal of our study was to evaluate the constancy of journals specialized in the field of urology and to analyze those listed in the 2005 Journal Citation Report (JCR) using the standardized methods specified by the Institute of Scientific Information (ISI) and JCR.
