Abstract:
Objective:To investigate the risk factors for the complications of urethroplasty in patients with primary hypospadias by postoperative follow-up observation.
METHODS:We retrospectively analyzed 110 cases of primary hypospadias repair performed from November 2010 to October 2015, including 70 cases of tubularized incised plate (TIP) urethroplasty and 40 cases of inlay internal preputial graft (IIPG) urethroplasty, all with the urethral plate reserved. We followed up the patients for 15.6－36 months, (27.3 ± 0.52) mo for those with and (26.9 ± 0.22) mo for those without complications. The mean age of the two groups of patients was (7.5 ± 0.2) and (7.0 ± 0.5) yr, respectively.
RESULTS:The follow-up data were collected from all the patients, 17 (15.5%) with and 93 (84.5%) without complications. The success rate of surgery was 84.5%. There were no statistically significant differences in the follow-up time and age between the two groups of patients (P >0.05). Single-factor analysis of variance showed significant differences between the complication and non-complication groups in the preoperative urethral opening (P <0.01), ventral penile curvature (P <0.01), and length of urethral defect (P = 0.04), while multiple linear regression analysis exhibited that only ventral curvature was associated with the postoperative complications of the patients (OR = 1.12, 95% CI: 1.06－1.19, P<0.01).
CONCLUSIONS:We chose single-stage urethroplasty with the urethral plate reserved for the treatment of primary hypospadias and achieved satisfactory outcomes. Ventral penile curvature is an independent risk factor for the complications of primary hypospadias, and a higher degree of curvature is associated with a higher incidnece of complications.
