Tissue engineering encompasses a multidisciplinary approach geared toward the development of biological substitutes designed to restore and maintain normal function in diseased or injured tissues. This article reviews the basic technology that is used to generate implantable tissue-engineered grafts in vitro that will exhibit characteristics in vivo consistent with the physiology and function of the equivalent healthy tissue. We also examine the current trends in tissue engineering designed to tailor scaffold construction, promote angiogenesis and identify an optimal seeded cell source. Finally, we describe several currently applied therapeutic modalities that use a tissue-engineered construct. While notable progress has clearly been demonstrated in this emerging field, these efforts have not yet translated into widespread clinical applicability. With continued development and innovation, there is optimism that the tremendous potential of this field will be realized. L’ingenierie tissulaire englobe une approche multidisciplinaire axee sur le developpement de substituts biologiques en vue de retablir et de maintenir la fonction normale de tissus leses. L’article qui suit passe en revue la technologie fondamentale utilisee pour generer des greffons implantables produits par ingenierie in vitro et possedant des caracteristiques in vivo correspondant aux tissus sains equivalents sur les plans physiologique et fonctionnel. Nous examinons egalement les tendances actuelles en ingenierie tissulaire visant a adapter des echafaudages tissulaires, a promouvoir l’angiogenese et a degager une source optimale de cellules implantables. Enfin, nous decrivons plusieurs modalites therapeutiques actuellement mises en application utilisant un echafaudage cree par ingenierie tissulaire. En depit de progres remarquables dans ce domaine en effervescence, les efforts deployes ne se sont pas encore traduits par une applicabilite clinique etendue. Des developpements et des percees continus permettent d’etre optimiste face au potentiel prodigieux de ce domaine.

Urethral defects originating from congenital malformations, trauma, inflammation or carcinoma still pose a great challenge to modern urology. Recent therapies have failed many times and have not provided the expected results. This negatively affects patients’ quality of life. By combining cells, bioactive molecules, and biomaterials, tissue engineering can provide promising treatment options. This review focused on scaffold systems for urethra reconstruction. We also discussed different technolo...

OBJECTIVE:To evaluate the mechanical properties of gastrointestinal (GI) tissue segments and to compare them with the urinary bladder for urinary tract reconstruction. METHODS:Urinary bladders and GI tissue segments were sourced from porcine models (n = 6, 7 months old [5 male; 1 female]). Uniaxial planar tension tests were performed on bladder tissue, and Cauchy stress-stretch ratio responses were compared with stomach, jejunum, ileum, and colonic GI tissue. RESULTS:The biomechanical properties...

Ileal conduit urinary diversion is the gold standard treatment for urinary tract reconstruction following cystectomy. This procedure uses gastrointestinal segments for bladder augmentation, a technique that is often associated with significant complications. The substantial progression in the fields of tissue engineering and regenerative medicine over the previous two decades has resulted in the development of techniques that may lead to the construction of functional de novo urinary bladder sub...

Bladder augmentation was first described in 1899. The goal at the time was to establish the ideal method to create a simple capacious reservoir for the safe storage of urine. That simple idea has over the last 100 years grown into one of the most dynamic areas in Pediatric Urology. Creative minds and hands from individuals in multiple disciplines have led us from creating a reservoir to the threshold of recreating a functional organ. In this review we look at the historical evolution of bladder ...

Pediatric urology patients often present with congenital or acquired tissue and organ dysfunction that requires surgical reconstruction to recreate the normal genitourinary systems functions. The traditional methods have varying degrees of donor site morbidity or inherent side effects. Tissue engineering is a developing field that aims to replace or regenerate these dysfunctional tissues and organs with cells, biomaterials, or a combination thereof. A tremendous amount of work has been done to t...

Abstract Introduction Enterocystoplasties are associated to complications. We developed a surgical technique for bladder autoaugmentation using autologous uterine flap in the rat, to try and improve the post-surgical evolution. Methods 36 female Wistar rats were randomly allocated into following groups: Group 1: Control ( n = 12) for analytical parameters, Group 2: Sham-operation hysterocystorrhaphy ( n = 12) and Group 3: Bladder autoaugmentation with autologous uterine flap ( n = 12). Two weeks...

In this Review, Kayes and colleagues discuss the aetiology, diagnosis and treatment options for congenital micropenis, acquired micropenis and penile dysmorphic disorder, including both nonsurgical and surgical techniques. They evaluate the role of phalloplasty and penile replacement surgery including transplantation, in this challenging clinical area.

Abstract The state of art of stem cell therapies in urologic regenerative medicine is still under development. There are still many issues before advances in tissue engineering can be introduced for clinical application. The essential question is whether stem cells should be seeded on the urinary tract lumen side. The present experiment, using Real-Time Cell Analyzer (RTCA) DP (Dual Plate) of the xCellligence system (Roche Applied Science, Mannheim, Germany), allowed us to monitor cellular event...

In this study, we have fabricated an artificial ureter by transplantation of in vitro-expanded urothelial cells onto an in vivo-prefabricated capsular stent using tissue engineering methods. Spiral poly (l-lactic acid) (PLLA) stents were transplanted into the subcutaneous of Wistar rats for a period of 1, 2 or 3 weeks to induce the formation of connective tissue capsules on their surfaces. The capsular PLLA stents were then decellularized and further recellularized with bladder epithelial cells ...
