Purpose: There is a lack of data on true long-term functional outcome of orthotopic bladder substitution. The primary study objective was to report our 35-year clinical experience.
Materials And Methods: Since October 1985, 259 male patients from a large single center radical cystectomy series with complete followup of more than 60 months (median 121, range 60-267) without recurrence, irradiation or undiversion that might have affected the functional outcome, were included.
Objective: To report the results using an extensive saturation biopsy in men with negative prostate biopsies but in whom there is still a clinical suspicion for carcinoma.
Patients And Methods: Between February 1999 and October 2004 we offered 40 patients (median age 63 years) an extensive saturation biopsy if there was clinical suspicion of prostate cancer after previous negative prostate biopsies. The median (range) number of cores taken was 64 (39-139) and was adjusted to the size of the prostate.
Purpose: To describe our experience with transrectal ultrasound (TRUS)-guided needle biopsy of pelvic malignancies.
Methods: Eleven patients with clinical suspecion of advanced malignant pelvic tumor were referred to our institution with a history of unsuccessful CT-guided biopsy, although a target lesion was demonstrated on pelvic CT or MRI. Cholin-PET and FDG-18-PET were also obtained individually in each patient.
Unlabelled: The ability of 11C-choline and multimodality fusion imaging with integrated PET and contrast-enhanced CT (PET/CT) was investigated to delineate prostate carcinoma (PCa) within the prostate and to differentiate cancer tissue from normal prostate, benign prostate hyperplasia, and focal chronic prostatitis.
Methods: All patients with PCa gave written informed consent. Twenty-six patients with clinical stage T1, T2, or T3 and biopsy-proven PCa underwent 11C-choline PET/CT after intravenous injection of 1,112 +/- 131 MBq 11C-choline, radical retropubic prostatovesiculectomy, and standardized prostate tissue sampling.
Organ-confined staging for bladder cancer has major impact on further treatment. Most imaging techniques for this purpose are insufficient. We, therefore, assessed the value and the limitations of a new diagnostic tool, the 3-D ultrasound (US) rendering, to distinguish invasive from noninvasive bladder cancers.

In this paper an attempt was made to find out which properties mainly predispose to these two tumor categories, and whether it is possible to predict the category from a battery of clinical and histopathological variables using newer methods of multivariate data analysis. The incidental prostatic carcinomas of the decade 1990-99 diagnosed at our department were reexamined.

In the present study, 50 pT2N0 and 28 pT3N0 prostatic adenocarcinomas were characterized by Gleason grading, comparative genomic hybridization (CGH), and histological texture analysis based on principles of stereology and stochastic geometry. The cases were classified by learning vector quantization and support vector machines.

For each chromosome region, one obtains the information whether there is a loss or gain of genetic material, or whether there is no change at that place. Therefore, large amounts of data quickly accumulate which must be put into a logical order.

Cases of complications requiring surgical revision are reported to be rare. We report on 6 patients with complications necessitating surgery.

Methods: Six patients ranging in age from 6 to 37 years with traumatic high-flow priapism underwent superselective embolization with gelatin sponges (n=3) or minicoils (n=3). Embolization was repeated up to 3 times.
Objectives: The genetic changes underlying the development and progression of prostate cancer are poorly understood. To identify chromosomal regions in incidental prostatic carcinoma (T1a and T1b) was the primary aim of this study.
Materials And Methods: We used comparative genomic hybridization (CGH) to search for DNA sequence copy number changes on a series of 48 T1 prostate cancer diagnosed by transurethral resection (TURP) and by adenomectomy.
Purpose: Lower ureteral calculi are accessible by transrectal endo-ultrasound, including 3-dimensional image processing with surface rendering. We analyzed the efficiency of this innovative technology compared with that of standard radiographic examinations with respect to the outcome of extracorporeal shock wave lithotripsy (ESWL) (Dornier Medical Systems, Marietta, Georgia).
Materials And Methods: In patients with prevesical or intramural calculi we performed excretory urography and transrectal endo-ultrasound using a Combison 530 device (Kretz Technik, Zipf, Austria) with integrated optional 3-dimensional image processing and surface rendering.
Traumatic high-flow priapism caused by a pathologic influx from lacerated arteries to the cavernous bodies is usually treated by transcatheter arterial embolisation. The purpose of this study was to evaluate a combined interventional approach with intraoperative perineal colour Doppler ultrasound (US) while performing the embolisation procedure. Our aim was to reduce radiation exposure and application of iodinised contrast media.

A total of 55 patients with urinary stones were examined by transabdominal 3-D ultrasound (US) with surface rendering of the stone. In calculi of the prevesical ureter, bladder and prostatic urethra, transrectal 3-D endosonography was performed as well.
