Objective: Photodynamic diagnosis (PDD) of superficial bladder cancer decreases recurrence rates. We present oncological results of a randomized, prospective study, comparing transurethral resection (TUR) performed under conventional white light (WL) with PDD. The follow-up period is the longest reported to date.

We compared the long-term results in patients with initial T1G3 bc treated with transurethral resection of the bladder (TURB), bacille Calmette-Guérin (BCG) instillations and repeat resection with special regard to these clinical risk factors. The aim was to determine if they influence the outcome in the bladder sparing approach for initial T1G3 bc.

The results have suggested a reduced rate of recurrent tumors with the use of 5-ALA fluorescence before bladder tumor resection. We performed a prospective, randomized trial to investigate whether the long-term tumor recurrence and residual tumor rates can be decreased using 5-ALA fluorescence diagnosis (FD).

While white light (WL) cystoscopy is considered to be the gold standard for transurethral resection of the bladder, photodynamic diagnostic (PDD) has been shown to improve final outcome. Escalating healthcare costs warrant increased effectiveness in treating noninvasive UCB.

Although vacuum therapy has been reported to expedite the healing of complex wound failures, vacuum-assisted closure (VAC) has been reported to be contraindicated in malignancy. In the present study we evaluated the use of VAC in the treatment of complex wound failures following inguinal lymphadenectomy for penile cancer in comparison to conventional wound care (CWC) implying debridement and saline-soaked gauze.

Reasons are the highly discrepant results obtained in the hitherto existing studies and the lack of an experimental system allowing the direct examination of chlamydial effects in the human vasculature. We established a human ex vivo organ culture model for the characterization of vascular chlamydial infection.

We performed a prospective, single institution, randomized trial to investigate whether the residual tumor rate and long-term tumor recurrence can be decreased by fluorescence diagnosis.
Materials And Methods: A total of 301 patients underwent transurethral resection of bladder tumors with white light or fluorescence diagnosis.
