PURPOSE
Recent research has suggested that glans penis size may be inversely associated with the likelihood of complications
after hypospadias repair and should therefore be included in prognostic models for surgical outcomes. Our aim was to
further evaluate whether objective measurement of glans penis width is predictive of complications, with subgroup
analyses based on preoperative testosterone use.
MATERIAL AND METHODS
We reviewed clinical data recorded at the time of prepubertal primary hypospadias repairs between July 2011 and
August 2014, as well as postoperative follow−up. Urethroplasty complications were defined as meatal stenosis,
dehiscence, fistula, or urethral stricture or diverticulum. The subset of meatal stenosis and dehiscence were regarded as
glanular complications. We performed logistic regression to determine association between glans width and
complications, with stratification by preoperative testosterone use.
RESULTS
Glans width was measured on 159 patients (median, 15 mm; range, 10−22 mm). Median postoperative follow−up was
6 months (interquartile range, 1−9 months). Twenty−two patients (14%) had one or more urethroplasty complications,
including 10 (6%) with glanular complications. Glans width was not significantly predictive of urethroplasty
complications overall (p=0.23) or glanular complications in particular (p=0.77). Lack of significant association between
glans width and complications was noted both in patients who did (n=84) and did not (n=75) receive testosterone
preoperatively (see Table).

CONCLUSIONS
Objective measurement of glans penis width was not predictive of complications after hypospadias repair, regardless of
preoperative testosterone use. These findings call into question whether glans size should be included in prognostic
models for outcomes of hypospadias repair.
