A case of simple supraurethral cleft was treated surgically with success. In December 2011, we admitted a child with simple supraurethral cleft to our hospital. The child, male, 3 years old, was admitted to the hospital for 3 years due to the discovery of penile deformity. On admission, he was seen to have an upturned penis, thick and short, separated ghost head, urethral opening on the dorsal side of the penis, thick urinary line, close range, and no urinary incontinence. He was treated surgically on December 19, 2011. Intraoperatively, the penile corpus cavernosum was separated and the urethra was extended obliquely from the root of the penis to the dorsal side of the penis. The dorsal penile vascular nerve bundle was preserved, the bilateral penile corpus cavernosum was separated to the cavernous pedicle of the penis root, the proximal urethral corpus cavernosum and the distal urethral plate mucosa were separated, the bilateral penile corpus cavernosum was closed, and the urethra was transferred to the ventral side of the penis, and the distal urethral plate mucosa was extended with multiple “Z” incisions, and the urethra was fixed to the ventral side of the penis in one stage. The urethra was fixed to the ventral side of the penis. Postoperative recovery was smooth with no complications. The incidence is about 1/95,000, male:female 4~8:1, and it is clinically classified into penile head type, penile body type, and complete type, which can be accompanied by different degrees of urinary incontinence. Preoperative urodynamic evaluation is required, along with voiding cystourethrography to understand bladder capacity and to exclude ureteral reflux. Surgical treatment is its only measure, and the choice of the procedure is particularly careful. Particular attention should be paid to the protection of the dorsal vascular nerve bundle of the penis during surgery, the wide mucosa of the urethral plate in this type of disease, and the urethral plate in place of the urethra can be urethroplasty in one visit.
