A multicenter evaluation of technical preferences for primary hypospadias repair.
OBJECTIVE
Considerable controversy exists regarding the optimal surgical technique for the repair of mid shaft and proximal hypospadias. We sought to evaluate differences in surgical preferences among an international cohort of pediatric urologists.


METHODS
An anonymous questionnaire containing relevant demographic data as well as choices of technique to repair 5 representative hypospadias cases was developed and administered.


RESULTS
Of 121 pediatric urologists contacted 101 completed the survey, representing an 83% response rate. The majority were full-time academic pediatric urologists who performed 6 to 10 hypospadias surgeries monthly. A total of 92 respondents (confidence interval [CI) 0.84 to 0.96) preferred the tubularized incised urethral plate (TIP) technique for the repair of distal hypospadias. Similarly, 82 (CI 0.72 to 0.88) preferred TIP for the repair of mid shaft hypospadias. The 2 most common techniques for repair of proximal hypospadias without chordee, preferred by 43 correspondents each (CI 0.33 to 0.53), were TIP and transverse island flap (TVIF) onlay. For repair of moderate (30-degree to 40-degree) chordee dorsal plication was preferred by 82 respondents, while a ventral approach was preferred by 12. When moderate chordee was associated TVIF onlay was preferred by 35 (CI 0.26 to 0.45) and TIP by 24 respondents (CI 0.16 to 0.34). For severe chordee (greater than 50 degrees) 31 respondents preferred dorsal plication, while 68 chose some form of ventral repair. Among the respondents 37 approach proximal hypospadias associated with severe chordee using a staged procedure, while 40 use a single stage procedure using a TVIF tube (CI 0.30 to 0.50). Using Spearman's rank correlation coefficient, no significant correlations were identified between respondent practice demographics and choice of repair for each hypothetical hypospadias case.


CONCLUSIONS
In this cohort of pediatric urologists we observed that the majority prefers TIP to repair distal and mid shaft hypospadiac defects. Significant variability exists for preferred technique for proximal hypospadias and chordee correction. These results support the need for prospective trials comparing techniques for the repair of proximal hypospadias.
