Design and Prototype an artificial urethra

Salim Boussofara

The human urethra is a complex tubular organ that allows to empty urine from the urinary bladder. Due to its hyperelastic properties and heterogeneous composition, the design of an artificial urethra (AU) is a real engineering challenge. Within the Center ...

3D laser shock peening as a way to improve geometrical accuracy in selective laser melting

Roland Logé, Nikola Kalentics, Andreas Burn, Michael Cloots

One of the major drawbacks of selective laser melting (SLM) is the accumulation of tensile residual stresses (TRS) in the surface and subsurface zones of produced parts which can lead to cracking, delamination, geometrical distortions, and a decrease in fa ...

Impedance pumping as a non-invasive treatment for underactive bladder? An ex-vivo proof-of-concept-study in porcine bladders.

Yves Perriard, Yoan René Cyrille Civet, Francesco Clavica

In patients suffering from underactive bladder (UAB), the contraction of the detrusor muscle has insufficient strength or duration to ensure efficient bladder emptying. Although catheterisation is currently the most effective method to empty the bladder, i ...

Is There a Need for Smooth Muscle Cell Transplantation in Urethral Reconstruction?

Peter Frey

Background: Hypospadias and urethral strictures are conditions requiring additional tissue for reconstruction. Due to a limited source of tissue, autologous skin and oral mucosa are frequently used. However, long-term follow-up studies demonstrated signifi ...

Geostatistical modelling for the monitoring of environmental-related endemic diseases: Application to the distribution of schistosomiasis in Burkina Faso

Laurent Hafiz

The increased interest of reducing the infection rates of neglected tropical diseases like schistosomiasis in the world has raised the necessity of developing epidemiological monitoring techniques, in order to target specific areas where the risk of infect ...

In-vivo performance of high-density collagen gel tubes for urethral regeneration in a rabbit model

Peter Frey, Jeffrey Alan Hubbell, Lionel Ambroise Micol

Congenital malformations or injuries of the urethra can be treated using existing autologous tissue, but these procedures are sometimes associated with severe complications. Therefore, tissue engineering may be advantageous for generating urethral grafts. ...
