Lymphocele incidence after kidney transplantation is as high as 18%. We retrospectively studied the therapy of 42 lymphoceles that occurred in our clinic between 1990 and 2005, focusing on possible predisposing factors for their formation and the results of several therapy variants: conservative, operative, percutaneous puncture, and laparoscopic or open(More)
Es werden die Ergebnisse einer nichtrandomisierten Vergleichsstudie zwischen offener und laparoskopischer Nephrektomie bei Patienten mit benignen Nierenerkrankungen vorgestellt. In den Jahren 1993–2002 wurden an der Klinik und Poliklinik für Urologie der Medizinischen Universität zu Lübeck und an der Universitätsklinik und Poliklinik für Urologie der(More)
Over the last few years, laparoscopy has become more common in urology. Nevertheless only a few centres carry out more than 40 laparoscopies a year. A reduction to two standard techniques has led to the simplification and time optimisation in preparation for surgery and thus to an increase in quality. Two standard positionings and trocar placements are(More)
We introduce here an improved design of the Uniform Marker Fields and an algorithm for their fast and reliable detection. Our concept of the marker field is designed so that it can be detected and recognized for camera pose estimation: in various lighting conditions, under a severe perspective, while heavily occluded, and under a strong motion blur. Our(More)
Currently, radical retropubic prostatectomy is the standard procedure for clinically localized prostate cancer. The surgical technique has been continuously refined for decades, resulting in reduced morbidity and improved functional and oncologic results. Since the late 90s, radical prostatectomy has been increasingly performed laparoscopically. A search of(More)
Structure prediction of non-canonical motifs such as mismatches, extra unmatched nucleotides or internal and hairpin loop structures in nucleic acids is of great importance for understanding the function and design of nucleic acid structures. Systematic conformational analysis of such motifs typically involves the generation of many possible combinations of(More)
A major limitation of contemporary fiduciary markers is that they are either very small (they try to represent a single point in the space) or they must be planar in order to be reasonably detectable. A deformable large-scale marker or marker field that would be efficiently detectable is the objective of this work. We propose a design of such a marker(More)
