OBJECTIVES To compare the outcome of hypospadias repair using tubularised incised-plate (TIP) urethroplasty and tubularisation of an intact and laterally augmented urethral plate. PATIENTS AND METHODS This prospective randomised study included 370 patients with primary distal hypospadias. All had urethral plate widths of 8-10 mm and a glans of ⩾15 mm. Exclusion criteria were previous repair, ...

INTRODUCTION There are different methods of urethroplasty in hypospadias. The present study aimed to compare the repair of the urethral plate by single vs. double layer suturing. MATERIAL AND METHODS Fifteen male rabbits were assigned to the control, single layer, and double layer urethral plate suturing groups (n = 5). Experimental hypospadias was induced in the second and third groups and t...

PURPOSE Controversy persists regarding the formation of human penile urethra. The classic fusion theory for the development of the spongy urethra and ectodermal ingrowth or endodermal transformation theories for the development of the glanular urethra do not explain the wide spectrum of anomalies seen in patients with hypospadias. This histological study was made to clarify the mechanism of ure...

PURPOSE Meatal stenosis is still a common problem in tubularized incised plate urethroplasty. In this study, we aimed to seek for a relationship between the size of urethral catheter and meatal stenosis formation in children undergoing tubularized incised plate urethroplasty. MATERIALS AND METHODS We retrospectively reviewed 83 children who underwent tubularized incised plate urethroplasty fo...

PURPOSE Buccal mucosa is a widely accepted tissue for urethroplasty. The exact healing and tissue integration process, mainly the histological characteristics of dorsal buccal mucosa graft urethroplasty when used dorsally to reconstruct the urethral plate has not previously been assessed, and thus we developed an experimental model to address this question. MATERIALS AND METHODS In 12 New Zea...

The role of VCU in the management of various urological conditions was discussed after retrospectively analyzing 197 voiding cysto-urethrograms performed on 167 cases. 1) The normal voiding is initiated when the base plate breaks open by virtue of its own contraction and continues smoothly while detrusor contraction follows toward the trigonal canal which is progressively transformed from the b...

background: the treatment of urethral stricture in female patients is through dilatation of the urethra by tubes of increasing diameter. there are two main methods: intermittent dilatation and on demand dilatation. objectives: the main aim of this study was to compare the results of these two methods, and to determine the best one. patients and methods: in this clinical trial study, we reviewed...

OBJECTIVE To present and evaluate our initial results with a modified double face onlay preputial flap (DOPF) for repair of different degrees of hypospadias. MATERIAL AND METHODS From April 2004 to April 2009, 182 patients with different degrees of hypospadias (distal penile hypospadias = 122, mid penile hypospadias = 38, proximal penile hypospadias = 22) were included in our study. All patie...

OBJECTIVE To assess the use of tunica vaginalis graft plus onlay preputial island flap in urethral reconstructive surgery in rabbits through histopathology. MATERIAL AND METHODS We developed an experimental model of urethroplasty that resembles one-stage complex hypospadias surgery with divided urethral plate. The tunica vaginalis graft is dorsally placed to recreate the urethral plate and th...
