This paper presents an index-based checkpointing algorithm for distributed systems with the aim of reducing the total number of checkpoints while ensuring that each checkpoint belongs to at least one consistent global checkpoint (or recovery line). The algorithm is based on an equivalence relation deened between pairs of successive c heckpoints of a process(More)
OBJECTIVE To report a prospective, controlled, non-randomized patient study to determine the systemic response to extraperitoneal laparoscopic (eLRP) and open retropubic radical prostatectomy (RRP). PATIENTS AND METHODS In all, 403 patients who had eLRP (163) or open RRP (240) were recruited; patients in both groups had similar preoperative staging. In(More)
OBJECTIVE To compare the oncological outcomes of laparoscopic radical nephroureterectomy (LNU) vs open NU (ONU) for upper urinary tract transitional cell carcinoma (TCC). PATIENTS AND METHODS Between July 1999 and January 2003, we performed 70 LNUs and 70 ONUs for TCC of the upper urinary tract. ONU was reserved for patients with previous abdominal(More)
PURPOSE The 4 most active centers of the laparoscopy working group of the German Urologic Association collected data about the complications associated with laparoscopic surgery in urology. MATERIALS AND METHODS At 4 centers 2,407 laparoscopies or retroperitoneoscopies were performed as of May 1998, including 776 for varicocelectomy, 259 for(More)
PURPOSE To present the current status of laparoscopic radical prostatectomy (LRP) in Germany, Austria and Switzerland with respect to transferability, learning curve, and outcome. MATERIAL AND METHODS The data of 5824 patients who underwent LRP in 18 centers by 50 urologists from March 1999 to August 2004 were analyzed retrospectively. Three centers(More)
The laparoscopic approach to the adrenal gland has evolved to be the gold standard for most cases of adrenal conditions requiring surgical treatment. There is general consent about the safety, efficacy, and reproducibility of laparoscopic adrenal surgery. Compared to the open surgery, significant advantages with regard to shorter hospitalization time,(More)
BACKGROUND Laparoendoscopic single-site surgery (LESS) has been developed in an attempt to further reduce the surgical trauma associated with conventional laparoscopy. Partial nephrectomy (PN) represents a challenging indication for LESS. OBJECTIVE To report a large multi-institutional series of LESS-PN and to analyze the predictors of outcomes after(More)
OBJECTIVES We report the results from a nonrandomized comparison of open flank versus laparoscopic nephrectomy in patients with benign renal disease. METHODS From January 1993 to December 1997, 249 nephrectomies for benign renal disease were performed at our institution. There were 118 patients in the open flank nephrectomy group (median age 58.5, range(More)
To compare the efficacy of digital rectal examination (DRE) and serum prostate specific antigen (PSA) in early detection of prostate cancer, we initiated a prospective multicenter screening trial. In 12,542 men choosen at random with a mean age of 62 (+/- 7.5) a suspect DRE or a PSA level > 4.0 ng/ml was found in 2343 (20%). Of the presently performed 744(More)
