Ureter reconstruction is a difficult procedure in urology. Adipose-derived stem cells (ADSCs), along with multipotency and self-renewal capacity, are a preferred choice for tissue engineering-based ureteral reconstruction. We explored the synergic role of cathelicidin LL37 (LL37) in epithelial and smooth-muscle-like differentiation. ADSCs were separated from adipose tissues of mouse and characterized by flow cytometry. The ADSCs were then stably transfected with pGC-FU-GFP (pGC) or pGC containing full-length LL37 (pGC-LL37), respectively...

OBJECTIVE: Precise pre-operative urethral stricture characterization is important for surgical planning. A period of urethral rest by suprapubic cystostomy tube may aid in stricture characterization and may affect the surgical approach. We compare the radiographic characterization of anterior urethral strictures by fellowship-trained reconstructive urologists before and after a period of urethral rest. We then determine how this changed the planned operative approach. METHODS: We queried our prospectively maintained urethroplasty database at the University of Minnesota for men with anterior urethral stricture who had retrograde urethrogram (RUG) and voiding cystourethrogram (VCUG) both before and after pre-operative suprapubic cystostomy tube (SPC) placement (n=29)...

Collagen and collagen-based materials have been successfully used in medicine for over 50 years. The number of scientific articles about the role of collagen in the construction of scaffolds for tissue engineering has risen precipitously in recent years. The review contains materials about historic and modern applications of collagen in medicine such as soluble collagen injections, solid constructs reconstructed from solution, and decellularized collagen matrices. The analysis of published data proves the efficacy of collagen material in the treatment of chronic wounds, burns, venous and diabetic ulcers, in plastic, reconstructive and general surgery, urology, proctology, gynecology, ophthalmology, otolaryngology, neurosurgery, dentistry, cardiovascular and bone and cartilage surgery, as well as in cosmetology...

Introduction: Genito Urinary Tuberculosis (GUTB) is a widespread disease seen in urology practice. The true incidence and prevalence of GUTB is difficult to estimate because a large number of patients remain asymptomatic. Aim: To recognize typical and atypical clinical and radiological features of tuberculosis and to emphasize the need for diagnosing GUTB early. Materials and Methods: This was a retrospective study conducted in 110 cases of GUTB diagnosed and treated in two teaching institutions over a period of three years, from July 2002 to June 2005...

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 of the bladder differed significantly to jejunum, ileum and colonic GI tissue...

BACKGROUND: Cloacal malformations represent a uniquely complex challenge for surgeons. The surgical approach to date has been based on the common channel (CC) length with two patient groups considered: less than or greater than 3cm, which we believe is an oversimplification. We reviewed 19 patients, referred after surgery done elsewhere. Eight had postoperative urinary complications, 3 had constant urinary leakage and had been left after surgery with a urethra <1cm, .5 with an original 3 to 5cm common channel, who had undergone total urogenital mobilization (TUM), experienced peri-operative urethral loss needing a vesicostomy, and later, a Mitrofanoff...

Although posterior urethral injury occurs almost always in association with pelvic fracture, it may result from severe trauma to the perineum with its associated potential lethality and severe morbidity. Early primary endoscopic realignment over a urethral catheter can be attempted, although an immediate suprapubic tube placement remains the standard of care. Definitive treatment consists of elective open posterior anastomotic urethroplasty through a perineal approach. The authors present a 53-year-old man who sustained total, massive perineal destruction resulting from work accident with an agricultural implement...

Bladder reconstruction remains challenging for urological surgery due to lack of suitable regenerative scaffolds. In a previous study, we had used a collagen-binding basic fibroblast growth factor (CBD-bFGF) to bind bFGF to the collagen scaffold, which could promote bladder regeneration in rats. However, the limited graft size in rodent models cannot provide enough evidence to demonstrate the repair capabilities of this method for severely damaged bladders in humans or large animals. In this study, the CBD-bFGF was used to activate a bladder acellular matrix (BAM) scaffold, and the CBD-bFGF/BAM functional scaffold was assessed in a canine model with a large segment defect (half of the entire bladder was resected)...

Regenerative medicine is a new branch of medicine based on tissue engineering technology. This rapidly developing field of science offers revolutionary treatment strategy aimed at urinary bladder regeneration. Despite many promising announcements of experimental urinary bladder reconstruction, there has been a lack in commercialization of therapies based on current investigations. This is due to numerous obstacles that are slowly being identified and precisely overcome. The goal of this review is to present the current status of research on urinary bladder regeneration and highlight further challenges that need to be gradually addressed...

INTRODUCTION: Magnamosis forms a compression anastomosis using self-aligning magnetic Harrison rings. The device has been approved by the Food and Drug Administration for first-in-human testing and has been applied in adults for intestinal anastomosis during urologic reconstructions. We now report the first cases of magnamosis to functionally undivert the fecal stream from a previously created loop ileostomy in pediatric patients. MATERIALS AND METHODS: Case 1: A 4-year-old male underwent a diverting loop ileostomy for malignant bowel obstruction...

INTRODUCTION: Mechanical bowel preparation (MBP) has historically been the standard of care for patients undergoing reconstructive urologic surgery, including urinary diversion. To date, several studies have examined the role of mechanical bowel preparation in postoperative outcomes in pediatric patients undergoing augmentation cystoplasty. However, these patient populations have been heterogeneous in nature, with no studies dedicated to examining the role of MBP prior to reconstructive urologic surgery in pediatric patients with myelomenginoceles...

PURPOSE: Overactive bladder (OAB) impacts over 15% of the adult population. Compliance with medical treatment is low, due either to inadequate symptom control or intolerable side effects. Although third line therapies have improved the treatment of OAB, many patients do not receive optimal treatment. We hypothesize that the utilization of third line treatment is higher among female pelvic medicine and reconstructive surgery urologists and examine its use in our tertiary referral center...
