OBJECTIVE: To investigate the mean preputial microvessel density (mMVD) and features of hypospadias and their relationship with the severity and early postoperative complications of the disease.
METHODS: Sixty children with hypospadias and another 14 age-matching ones with phimosis (the control group) underwent penile curvature correction, Snodgrass procedure or staged surgery, the excessive dorsal foreskin trimmed and retained. We determined the mMVD in the prepuce tissue of the patients by immunohistochemistry, and followed up those treated by Snodgrass procedure.
RESULTS: The mMVD was significantly lower in the patients with severe hypospadias than in those with mild hypospadias and the controls (15.51 ± 3.53 vs 19.27 ± 4.42 and 22.09 ± 6.15, P < 0.05), with a median of 21.8 in the control group. The incidence of postoperative complications was obviously lower in the high mMVD (≥ 21.8) than in the low mMVD (< 21.8) group.
CONCLUSIONS: The preputial mMVD is significantly lower in patients with severe hypospadias than in normal children, decreasing in a severity-dependent manner. The lower the preputial mMVD, the higher the incidence rate of postoperative complications. The preputial mMVD of 21.8 can be used as a reference index for evaluating the prognosis of surgery clinically. ?
