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)
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 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 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)
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)
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)
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)
The aim of this study was to determine whether p53 is helpful in making the decision to undergo cystectomy in T1, G3 transitional cell carcinoma (TCC) of the bladder, by prospectively comparing the p53 status of bladder biopsies with the histology and p53 status of the corresponding cystectomy specimens. From January 1996 to August 1997, 38 consecutive(More)
pT1 G3 bladder carcinomas are heterogeneous with respect to tumor recurrence and progression. Whereas some urologists treat these carcinomas by repeated transurethral resections often followed by intravesical chemotherapy or BCG instillation, others recommend cystectomy after tumor recurrence or early cystectomy after the initial diagnosis. Our goal was to(More)
