DIAGNOSTICO

• Hipospadia es diagnosticada por el examen físico,

sospechada inicialmente por la disposición del

prepucio y confirmada por la ubicación ventral del

meato.

ORTOPLASTIA

• corrección de la curvatura ventral

• tejidos ventrales: piel, dartos, cuerpo

esponjoso, placa uretral , y túnica del cuerpo

cavernoso. todos ellos creando tensión para

producir curvatura ventral.

• ocurre en 11% de hipospadia distal, 30%

medio peneana, 81% en proximal.

• para evaluar la curvatura real el primero paso es tener

el pene en erección total.

• otro requisito es tener el pene liberado del prepucio.

• técnica de Baskin: las

curvaturas mayores de

30º pueden ser resueltas

técnica de Nesbit:

• apertura longitudinal y

cierre transversal

escisión de piel en el

segmento contralateral a

1. Introduct ion

Hypospadias is the most common malformation of the

penis, and literally countless techniques for its repair have

been described [1]. In large, systematic reviews of various

types of hypospadias correction, no urethroplasty tech-

nique appears to be definit ively superior. Moreover,

comparison between series in the literature is challenging

because of a lack of reliability in reporting outcome, which

complicates creation of universal recommendations [2–4] .

In 2009, the European Association of Urology published

guidelines for the treatment of hypospadias, with a level of

evidence between case series and systematic reviews of

cohort studies with or without homogeneity [5]. In clinical

practice, many factors influence the choice of surgical

technique, including ‘‘personal taste, upbringing, situation-

al preference, training, experience and personal success’’

[6]. For that reason, we sought to determine which

Abstract

Background: Hypospadias is a challenging field of urogenital reconstructive surgery,

w ith different techniques currently being used.

Objective: Evaluate international trends in hypospadias surgery.

Design, sett ing, and part icipants: Paediatric urologists, paediatric surgeons, urologists,

and plastic surgeons worldwide were invited to part icipate an anonymous online

questionnaire (http://www.hypospadias-center.info).

Measurements: General epidemiologic data, preferred technique in the correction of

hypospadias, and preferred technique in the correction of penile curvature were

gathered.

Results and limitat ions: Three hundred seventy-seven part icipants from 68 countries

returned completed questionnaires. In distal hypospadias (subcoronal to midshaft), the

tubularised incised plate (TIP) repair is preferred by 52.9–71.0% of the part icipants.

Meatal advancement and glanuloplasty (MAGPI) is stil l a preferred method in glandular

hypospadias. In the repair of proximal hypospadias, the two-stage repair is preferred by

43.3–76.6%. TIP repair in proximal hypospadias is used by 0.9–16.7%. Onlay flaps and

tubes are used by 11.3–29.5%of the study group. Simple plication and Nesbit ’s proce-

dure are the techniques of choice in curvature up to 308; urethral division and ventral

incision of the tunica albuginea with graft ing is performed by about 20% of the

part icipants in severe chordee. The frequency of hypospadias repairs does not influence

the choice of technique.

Conclusions: In this study, we ident ified current international trends in the management

of hypospadias. In distal hypospadias, theTIPrepair is thepreferred technique. In proximal

hypospadias, the two-stage repair is most commonly used. A variety of techniques are

used for chordee correction. This study contains data on the basis of personal experience.

However, future research must focus on prospective controlled trials.
