Abstract:
Objective:To summarize the ideal strategy for the treatment of female hypospadias.Methods:The data of 12 female patients with hypospadias admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from December 2011 to December 2019 were retrospectively analyzed. The patients was (31.0±16.6) years old (7-67 years old). Among them, 3 cases had a history of pelvic fracture trauma, 3 cases had a history of birth trauma, and the remaining 6 cases had no history of trauma and surgery. Among them, there were 6 cases of congenital hypospadias and 6 cases of acquired hypospadias. The clinical manifestations were urinary incontinence in 6 cases and dysuria in 6 cases. Examination of the normal position of the external opening of the genital urethra did not show the opening of the urethra, but moved down to different parts of the anterior wall of the vagina. All patients underwent urethral lengthening. For congenital hypospadias, the urethral plate is used to cut the coiled tube during the operation to prolong the urethra. For acquired hypospadias, the stenotic urethra was enlarged and lengthened with a labial pedicled flap coil. The subcutaneous fat pad of the labia majora was mobilized and transferred to the outside of the newly constructed urethra to prevent the occurrence of urethro-vaginal fistula and increase the pressure of the urethra. Five patients with significant urinary incontinence underwent bladder neck reconstruction at the same time. Anatomical success of the procedure was defined as the appearance of a normal-shaped external urethral opening beneath the clitoris. Functional success was defined as the absence of moderate to severe urinary incontinence after surgery, and the maximum urinary flow rate was >15ml/s during the 12-month follow-up period.Results:All operations were successfully completed. All patients had no perioperative complications, and were followed up for 18-96 months, with an average of 57.3±32.5 months. All patients were able to urinate spontaneously after operation, 4 cases of urinary incontinence disappeared, and 2 cases improved significantly; 4 cases of patients with strenuous urination urinated smoothly. The remaining 2 cases still complained of dysuria after operation, which was solved by subsequent urethral dilatation. The anatomical repair success rate was 100.0%(12/12) and the functional success rate was 83.3% (10/12).Conclusions:Urethral lengthening is an effective method for female hypospadias. The pedicled fat pad helps to increase urethral pressure and prevent fistulas. For female patients with hypospadias and severe urinary incontinence, bladder neck reconstruction is an ideal method. of the technique.
