We present a new concept on how to remove unwanted green fluorescence from urine during Photodynamic Diagnostics of tumours in the bladder using cystoscopy. A high power LED based light source (525 nm) has been made in our laboratory. This light source is tailored to match most commercially available rigid cystoscopes.

A suitable spectral filter and adapter, for the eyepiece of the cystoscope, has been selected which allows the urologist to observe both red fluorescence from tumours and autofluorescence from healthy tissue at the same time.
