Creation of Tissue-Engineered Urethras for Large Urethral Defect Repair in a Rabbit Experimental Model.

Tissue engineering is a potential source of urethral substitutes to treat severe urethral defects. Our aim was to create tissue-engineered urethras by harvesting autologous cells obtained by bladder washes and then using these cells to create a neourethra in a chronic large urethral defect in a rabbit model. A large urethral defect was first created in male New Zealand rabbits by resecting an elliptic defect (70 mm) in the ventral penile urethra and then letting it settle down as a chronic defect for 5-6 weeks.

Long-Term Renal Transplant Outcome in Patients With Posterior Urethral Valves. Prognostic Factors Related to Bladder Dysfunction Management.

To obtain a successful renal transplant (RT) outcome in patients with posterior urethral valves (PUV), it is necessary to accomplish an adequate bladder dysfunction treatment. Our aim was to determine prognostic factors related to bladder dysfunction management in long-term RT outcome in patients with PUV. A retrospective review of patients with PUV who received a first RT after 1985 in our institution with at least 5 years of follow-up was performed.

Long-term outcomes of adult-size and size-matched kidney transplants in small pediatric recipients.

Introduction: Adult-size kidneys are usually used for kidney transplantation in small pediatric recipients, but the influence of graft size in transplant outcome remains controversial. Our aim is to compare long-term transplant outcomes of using adult-size and size-matched kidneys in small pediatric recipients.

Materials And Methods: Since 1999, 61 of 226 kidney transplants were achieved in recipients weighing <20 kg with 5 years of follow-up.

Predicting Full Enteral Feeding in the Postoperative Period in Infants with Congenital Diaphragmatic Hernia.

 The objective of the study is to examine the factors associated with time to achieve full enteral feeding after repair of congenital diaphragmatic hernia.  Demographic, clinical, and therapeutic data were retrospectively assessed, and uni- and multivariate Cox regression were performed to examine factors predictive of achieving full enteral feeding that was defined as time to achieve120 mL/kg/d after surgical repair.  Of 78 infants, 66 underwent intervention before hospital discharge.

Mesohepatectomy for Centrally Located Tumors in Children.

Introduction: Central hepatectomy or mesohepatectomy (MH) is a complex surgical technique rarely used in children. It is indicated in central tumors to preserve functioning liver mass avoiding an extended right hepatectomy. The purpose of this article is to analyze our experience with this technique.

Surgical Rehabilitation Techniques in Children with Poor Prognosis Short Bowel Syndrome.

Intestinal failure (IF) requires a multidisciplinary management based on nutritional support, surgical and medical rehabilitation, and transplantation. The aim of this study is to review our experience with surgical rehabilitation techniques (SRTs: enteroplasty, Bianchi, Serial Transverse Enteroplasty Procedure [STEP]) in patients with short bowel syndrome (SBS) and poor prognosis due to complex abdominal pathology. We performed a single-center retrospective study of patients with IF evaluated for intestinal transplantation in the Intestinal Rehabilitation Unit who underwent an SRT.

Congenital Portosystemic Shunts: Clinic Heterogeneity Requires an Individual Management of the Patient.

Introduction: Congenital portosystemic shunt (CPSS) is a rare entity without insufficiency in treatment issues. The aim of this article is to show our experience in the heterogeneity of this condition.

Material And Methods: A retrospective study of 25 CPSS in the period 1995 to 2014 was conducted.

Portal Cavernoma in the Era of Mesoportal Shunt (Rex) and Liver Transplant in Children.

Objective: The mesoportal shunt (MPS) and liver transplantation (LT) have changed the scenario of extrahepatic portal vein obstruction (EHPVO) since the MPS, the only "curative" technique, can now be offered in asymptomatic patients and also thrombotic complications of LT have increased the incidence of EHPVO.

Material And Methods: A retrospective study of patients undergoing surgery for EHPVO was conducted between 1990 and 2015. An analysis was done for the shunt permeability and clinical evolution over time.

Quality of Life in Female Epispadias.

Introduction and Aim Female epispadias is a rare congenital anomaly associated with significant urinary incontinence. This study aims to evaluate the results of its treatment in terms of continence, sexuality, and impact of incontinence on quality of life. Materials and Methods We retrospectively reviewed nine patients (5-39 years) treated of female epispadias in our hospital during the period 1976-2013.
