Multisystem Neuroprosthetic Training Improves Bladder Function After Severe Spinal Cord Injury

Grégoire Courtine, Rubia van den Brand, Daniel Eberli

Severe spinal cord injury leads to neurogenic bladder dysfunction. We recently developed a multisystem neuroprosthetic training program that promotes plastic changes capable of restoring refined locomotion in rats with severe spinal cord injury. We investi ...

Hydrogels for Urinary Tract Tissue Engineering

Lionel Ambroise Micol

Several urinary tract disorders, such as hypospadias or bladder cancer, require reconstructive surgery to preserve the patient's quality of life and at times even save their life. The current available surgical treatments, involving grafts from other tissu ...

Endoscopic Fluorescence Imaging

Blaise Lovisa

Since several decades, the physicians are able to access hollow organs with endoscopic methods, which serve both as diagnostic and surgical means in a wide range of disciplines of the modern medicine (e.g. urology, pneumology, gastroenterology). Unfortunat ...

Fluorescence of the bladder washout fluid following cystoscopy: a preliminary study

Hubert van den Bergh, Georges Wagnières, Anna Maria Novello, Blaise Lovisa

During fluorescence cystoscopy, it is observed that the acquired images are sometimes blurred by a greenish background originating from the bladder washout fluid. Several fluorophores are involved in this overall liquid fluorescence, and their exact origin ...

Detection of early bladder carcinoma by fluorescence cystoscopy with Hexvix: optical characterization of a high magnification cystoscope

Hubert van den Bergh, Georges Wagnières, Blaise Lovisa

Fluorescence detection of early superficial bladder cancer has been well established over the last years. This technique exploits the selective production and accumulation within cancerous tissues of photoactive porphyrins (PaP), mainly protoporphyrin IX ( ...

On the influence of the instillation time on the results of HAL (Hexvix®) fluorescence detection of superficial bladder cancer

Hubert van den Bergh, Georges Wagnières

Hexyl aminolevulinate (HAL) fluorescence cystoscopy is being investigated as a new diagnostic tool for the detection of flat urothelial malignancies in bladder cancers. However, the influence of the bladder instillation time on the performance of this dete ...

Human urothelial cells grown on collagen adsorbed to surface-modified polymers

Florian Maria Wurm, Peter Frey

OBJECTIVES: Tissue engineering methods can be applied to regenerate diseased, or congenitally missing, urinary tract tissues. Urinary tract tissue cell cultures must be established in vitro and adequate matrices, acting as cell carriers, must be developed. ...

Clinical evaluation of a method for detecting superficial transitional cell carcinoma of the bladder by light-induced fluorescence of protoporphyrin IX following topical application of 5-aminolevulinic acid: Preliminary results

Hubert van den Bergh, Georges Wagnières

BACKGROUND AND OBJECTIVE: In bladder cancer, conventional white light endoscopic examination of the bladder does not provide adequate information about the presence of "flat" urothelial lesions such as carcinoma in situ. In the present investigation, we ex ...

Usefulness of fluorescence photodetection of neoplastic urothelial foci in bladder cancer following intravesical instillation of delta-aminolevulinic acid (5-ALA)

Hubert van den Bergh, Georges Wagnières

An excellent knowledge of histopathological risk factors of superficial bladder transitional cell carcinoma is mandatory to establish the prognosis of the disease. Presence or absence of carcinoma in situ (CIS) in superficial bladder cancer is one of the m ...
