[Sun's coronal sulcus ring incision plus suprapubic liposuction versus suprapubic V-Y incision for penile elongation].

Objective: To investigate the clinical effect of suprapubic V-Y incision versus that of Sun's coronal sulcus ring incision plus suprapubic liposuction (CSRI+SPLS) for penile elongation.

Methods: From December 2010 to January 2018, 100 adult males with congenital short penis underwent suprapubic V-Y incision (the V-Y group, n = 50) or CSRI+SPLS (n = 50) for penile elongation surgery in our department. We statistically analyzed the clinical data on the two groups of patients, including age, body mass index (BMI), pre- and post-operative penile lengths in flaccid and erectile states, operation time, intraoperative blood loss, postoperative use of analgesics, postoperative hospital stay, stage-Ⅰ wound healing, incidence of postoperative complications, and quality of pre- and post-operative sexual life.

Results: The average ages of the patients in the V-Y and CSRI+SPLS groups were 23.5 and 23.0 years, their BMIs (26.59 ± 1.16) and (26.44 ± 0.96) kg/m2, preoperative flaccid penile lengths (5.11 ± 0.30) and (5.12 ± 0.35) cm, preoperative erectile penile lengths (7.57 ± 0.65) and (7.35 ± 0.59) cm, postoperative flaccid penile lengths (7.80 ± 0.40) and (7.79 ± 0.42) cm, postoperative erectile penile lengths (11.59 ± 0.55) and (11.47 ± 0.64) cm, none with statistically significant difference between the two groups (P > 0.05). Compared with the V-Y group, the CSRI+SPLS group showed a markedly shorter operation time (108 ［90－120］ vs 51 ［45－58］ min, P < 0.01), less intraoperative blood loss (30 ［15－45］ vs 15 ［5－25］ ml, P < 0.01), shorter postoperative hospital stay 8 ［6－11］ vs 4 ［2－6］ d, P < 0.01), lower incidence rates of postoperative hematoma (23.33% ［7 cases］ vs 0, P < 0.05) and infection (20.00% ［6 cases］ vs 0, P < 0.05), higher stage-Ⅰ healing rate (76.67% ［23 cases］ vs 100.00% ［30 cases］, P < 0.05), lower rate of postoperative use of analgesics (26.67% ［8 cases］ vs 3.33% ［1 case］, P < 0.05), and higher score on the quality of postoperative sexual life (36.73 ± 5.41 vs 42.07 ± 3.64, P < 0.01) though with no statistically significant difference preoperatively (28.70 ± 4.87 vs 28.27 ± 3.40, P > 0.05).

Conclusions: As a surgical procedure for penile elongation, Sun's coronal sulcus ring incision plus suprapubic liposuction is superior to suprapubic V-Y incision for its advantages of lower invasiveness, shorter operation time, less intraoperative blood loss, and lower incidence of postoperative complications.
