Abstract:
Objective:To investigate the clinical effect of progressive transfer of penile flap combined with local scrotal flap in correction of severe concealed penis in children.Methods:The clinical data of children with severe concealed penis admitted to the Children’s Hospital Affiliated to Zhengzhou University from July 2021 to July 2023 were retrospectively analyzed. The concealed penis was corrected by progressive transfer of penile flap combined with local scrotal flap. During the operation, a small amount of excess inner prepuce was removed and the outer prepuce was cut in the middle of the dorsal side of the penis. Then the penile flap was transferred from dorsal to ventral, gradually covering the wound without tension. The local scrotal flap was lifted upwards and sutured to the frenulum for covering the ventral foreskin defect of the penis. The amount of blood loss during the operation was recorded. The pain tolerance, the duration of prepuce edema, the length of penis extension and the healing of skin flap were observed. The appearance of the penis was followed up to observe whether the penis was retracted, and the satisfaction of the children and their guardians was recorded.Results:A total of 32 male children were enrolled, ranging in age from 3 to 10 years, with an average age of 7.2 years. The penis of all the children had a conical appearance, and the penile shaft was buried under the subcutaneous anterior pubis, which was difficult to palpate in its natural state. The average intraoperative blood loss was about 5 ml. All patients had pain after the operation. Two patients needed a pump to relieve pain, and the rest could tolerate it after rectum administration of indomethacin suppositories. The edema of the prepuce was mild after the operation, and the edema basically disappeared when the patient was discharged 7-9 days later. The penis could be lengthened by 1.5-3.0 cm under static conditions, averaging about 2.0 cm. After surgery, only 1 patient had a small area (about 5 mm × 4 mm) of infection in the scrotal flap and poor incision healing, and scar healing after dressing change and intensive nursing. The other flaps healed well. After 6 to 12 months of follow-up, the penis length of 2 cases was slightly retracted from the time of discharge, and the remaining 30 cases had no significant change. The patients and their guardians were satisfied with the operation results.Conclusion:The progressive transfer of penile flap combined with local scrotal flap correction of severe concealed penis in children can fully lengthen the penile body, and the degree of postoperative retraction is low, the appearance of the penis is good, and the patient satisfaction is high.
