Trends in hypospadias surgery: results of a worldwide survey.

Background: Hypospadias is a challenging field of urogenital reconstructive surgery, with different techniques currently being used.

Objective: Evaluate international trends in hypospadias surgery.

Design, Setting, And Participants: Paediatric urologists, paediatric surgeons, urologists, and plastic surgeons worldwide were invited to participate 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 Limitations: Three hundred seventy-seven participants 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 participants. Meatal advancement and glanuloplasty (MAGPI) is still 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 procedure are the techniques of choice in curvature up to 30°; urethral division and ventral incision of the tunica albuginea with grafting is performed by about 20% of the participants in severe chordee. The frequency of hypospadias repairs does not influence the choice of technique.

Conclusions: In this study, we identified current international trends in the management of hypospadias. In distal hypospadias, the TIP repair is the preferred 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.
