Abstract

Objectives: To establish a standard surgical procedure for children with chordee with a paper-thin hypoplastic urethra, which was based on the degree of curvature and urethral plate quality. To guidelines for the management of this disorder.

Methods: We reviewed 58 cases of chordee with a paper-thin hypoplastic urethra, managed between March 2006 and September 2020. The age of the patients ranged from 23 to 89 months. Operative details and postoperative complications were analyzed.

Results: Mild-moderate chordee with a paper-thin hypoplastic urethra correction was performed using a tubularized incised plate (13 cases) or onlay island flap (five cases) technique after penile degloving. Severe chordee with a paper-thin hypoplastic urethra required transection of the urethra and underwent a Duckett (11 cases) or staged (29 cases) urethroplasty. Complications in the tubularized incised plate and onlay island flap groups were 7.7% and 20%, respectively. The overall complication rate was 10.3% in the staged group and 27.3% in the Duckett group.

Conclusions: Reconstruction of the entire hypoplastic urethra should be recommended in the management of chordee with a paper-thin hypoplastic urethra. We propose an algorithm based on the degree of curvature and urethral plate quality. The tubularized incised plate or onlay island flap technique can be used for mild to moderate chordee with a paper-thin hypoplastic urethra, and the outcome of the tubularized incised plate technique tends to be better than that of the onlay island flap technique. Duckett or staged urethroplasty is suitable for severe chordee with a paper-thin hypoplastic urethra, and the staged technique can improve the overall success rate.
