Modified penile augmentation by dermal-fat graft in post-operative hypospadias adults / 中华整形外科杂志

ABSTRACT

Objecive@#To assess the clinical outcomes of patients who received modified penile augmentation by free dermal-fat grafting.@*Methods@#From April 2012 to December 2014, a total of 15 male adults (18-24 years of age) after hypospadias repairs were included. They underwent modified penile augmentation, including girth enhancement using free dermal-fat grafting, and penile elongation (suprapubic skin advancement-ligamentolysis). Penile measurements were performed using ruler before operation and 6 months after operation. The outcome was evaluated by patients, based on the Male Genital Image Scale. SPSS 22.0 was used to analyze the data. In-paired t-test and Wilcoxon test were applied.@*Results@#In 6-84 months of follow-up, all patients achieved excellent cosmetic results, and satisfied with the appearance and diameter. In weak state, the penile length increased from (5.03±0.47) cm to (6.69±0.49) cm. The increased value was (1.67±0.24) cm (t=8.6, P<0.001). Under traction, the penile length increased from (7.29±0.74) cm to (9.21±0.73) cm. The increased value was (1.93±0.21) cm (t=7.8, P<0.001). In weak state, the diameter of the middle part of penis increased from (7.16±0.25) cm to (8.69±0.44) cm, with the increased value of (1.53±0.23) cm (t=8.2, P<0.001). The MGIS score grew from 31.73±4.86 to 40.20±4.54(Z=3.2, P=0.001).@*Conclusions@#This modified technique is safe and effective in enlarging penile size for patients who had underwent hypospadias repair. It is confirmed that physical dimensional enhancement does contribute to improving their self-estimation of penile size.
