Introduction: Bladder exstrophy (BE) is a rare, complex malformation. There are three major approaches to closure. Despite this choice, abdominal wall closure in such patients is usually a challenging procedure specially in large defects and redo cases.

A large number of surgical techniques for the treatment of POM been proposed aiming mainly to reduce renal damage by relieving the affected ureter. Resection of the affected ureteral segment followed by vesicoureteral reimplantation either with or without reduction ureteroplasty is the classic treatment, however posing a high rate of complications when performed in patients aged less than one year.

This paper aims to separate this complex anomaly into different diseases, each with distinct clinical forms according to the disturbance during embryogenesis, yet noting a few similarities that may be helpful in their management. The classification system of urethral duplication is also discussed.

Introduction: Androgen actions are exerted upon the androgen receptor (AR), and complete genital virilization of normal 46,XY individuals depends on adequate function and expression of the AR gene in a tissue-specific manner.
Objective: Standardization of normal ARmRNA in androgen-sensitive tissues.
Materials And Methods: In this study, we determined the quantitative amounts of ARmRNA in peripheral blood mononuclear, urethral mucosa and preputial skin cells of control subjects with phimosis by using RT-PCR.
Purpose: Trauma injuries of the posterior urethra resulting from pelvic fracture in children tend to be complete ruptures, with upper dislocation of the prostate. This paper aims to show our experience in using an anterior sagittal transanorectal approach (ASTRA) in the treatment of such injuries.
Materials And Methods: The medical records of 11 patients with pelvic fracture urethral distraction defects who had undergone anastomotic urethroplasty through ASTRA between 1997 and 2009 were reviewed.
Previous studies described controversial opinions about pediatric tracheotomy concerning type of tracheal incision and long-term results, which remain as important research subjects. Experimental studies on rat tracheas are scarce, probably because of technical difficulties related to the structures' small dimensions. As many rat organ and system operative procedures were studied successfully by using microsurgical techniques, we decided to develop a pediatric tracheotomy model in growing rats which would permit long-term studies.

Grafts from C57BL/6 fetal intestines were implanted in an avascular form in BALB/C recipients. A syngeneic group of animals was used to compare the evolution.
