Lower Urinary

The urethra is part of the lower urinary tract and its main role is urine voiding. Its complex histological structure makes urethral tissue prone to various injuries with complicated healing processes that often lead to scar formation. Urethral stricture disease can affect both men and women. The occurrence of this pathology is more common in men and thus are previous research has been mainly oriented on male urethra reconstruction. However, commonly used surgical techniques show unsatisfactory results because of complications. The new and progressively developing field of tissue engineering offers promising solutions, which could be applied in the urethral regeneration of both men´s and women´s urethras. The presented systematic review article offers an overview of the cells that have been used in urethral tissue engineering so far. Urine-derived stem cells show a great perspective in respect to urethral tissue engineering. They can be easily harvested and are a promising autologous cell source for the needs of tissue engineering techniques. The presented review also shows the importance of mechanical stimuli application on maturating tissue. Sufficient vascularization and elimination of stricture formation present the biggest challenges not only in customary surgical management but also in tissue-engineering approaches.

Choice Of Technique

There are no particularly important technical aspects to urethra reconstruction in the elderly compared to younger patients, but the surgical indications and especially the choice of technique must be carefully assessed. The risk factors which may influence the result of a urethroplasty in the elderly are: senescence of the urinary apparatus, ischemia, psychological instability. It is therefore vital not to jeopardise the urethral vascular fragility of elderly patients with an operation. The concept of vessel sparing is very important in urethroplasty in the elderly in order to preserve terminal vascularisation of the bulbar arteries as much as possible. A retrospective review of 98 patients (aged 12-82 years) who underwent urethroplasty showed that there is a greater risk of ischemia when free skin flaps exceeding 4 cm are used. Furthermore, urethroplasty divided into two sessions with temporary perineal urethrostomy can cause psychological disturbance in the elderly, often aggravating sub-latent clinical depression.

Tissue Engineering Technology

Urethral stricture is a disease characterized by a pathological narrowing of the urethra. Treatment for this condition often requires surgery using autologous grafts (urethroplasty). It is common practice to use patient’s own tissue like genital and extragenital skin, tunica vaginalis, buccal mucosa as a source of the graft. Alternative and safer approach is to use tissue-engineered graft created in a laboratory using patient’s autologous cells and biocompatible matrix (scaffold). The article presents the up-to-date achievements in lab-created tissue-engineered graft, describes all components needed to build a tissue-engineered structure of the graft for urethroplasty, and summarizes authors’ thoughts on advantages and disadvantages of various approaches to choose both cellular component and the matrix of future construction. The article reviews clinical studies conducted in the field of tissue engineering of the graft material for urethraplasty.
