OBJECTIVE To determine the need to standardize the number and location of lymph nodes to be removed during radical cystectomy in patients with invasive bladder carcinoma. PATIENTS AND METHODS The pelvic lymph nodes from 447 patients (mean age 62.8 years) who underwent radical cystectomy between 1986 and 1997 were evaluated. The number of lymph nodes was(More)
PURPOSE Previous studies demonstrate a positive correlation between postoperative survival and the extent of pelvic lymphadenectomies in patients with bladder cancer. However, the distribution of nodal metastases has not been examined in sufficient detail. Therefore, we conducted a comprehensive prospective analysis of lymph node metastases to obtain(More)
PURPOSE Data on the prognostic significance of tumor invading lymphatic and blood vessels in bladder cancer are controversial, while little is known about perineural invasion in this tumor. We determined the prognostic value of these parameters in radical cystectomy specimens. MATERIALS AND METHODS Slides of 283 radical cystectomy specimens obtained from(More)
PURPOSE To study safety, feasibility, and biologic activity of adenovirus-mediated p53 gene transfer in patients with bladder cancer. PATIENTS AND METHODS Twelve patients with histologically confirmed bladder cancer scheduled for cystectomy were treated on day 1 with a single intratumoral injection of SCH 58500 (rAd/p53) at cystoscopy at one dose level(More)
PURPOSE We question the statement that anti-refluxing ureteral implantation is mandatory in low pressure, high capacity reservoirs. In a series of patients with ureteral obstruction after implantation with an anti-refluxing submucosal tunnel reimplantation was performed as a direct ureter-pouch anastomosis. The same technique was used for primary(More)
PURPOSE Voiding dysfunction and urinary retention are rare complications of antireflux surgery. As mainly reported after bilateral antireflux surgery with extravesical technique, bladder insufficiency has been suspected to be caused by intraoperative damage to neural structures. We studied the topography of the pelvic plexus and assessed the injury to the(More)
OBJECTIVES Urinary diversion after previous pelvic irradiation is challenging. The use of irradiated bowel in particular is associated with an increased rate of early and late complications. We therefore performed continent cutaneous urinary diversion using exclusively nonirradiated bowel segments in this group of patients. METHODS A continent colon pouch(More)
OBJECTIVE To analyse, in a retrospective study, the oncological outcome, pouch-related complications, continence and micturition after radical cystoprostatectomy combined with Mainz pouch orthotopic bladder substitution to the urethra for the treatment of bladder cancer. PATIENTS AND METHODS Between 1986 and 1996, three urological departments contributed(More)
