Abstract:
Objective:To evaluate the safety and efficacy of tabularized urethral plate disassembly for epispadias repair in infant.
Methods:From January 2016 to September 2018, 10 boys aged between 18 to 36 months old with mishaft epispadias were included. The main complaint was that the urethral opening was found on the dorsal side of the penis. Preoperative cystography revealed that 3 of them had unilateral vesicoureteral reflux (Grade Ⅰ), and white blood cells in routine urinary in all 10 patients were negative. Physical examination: the penis is short and flat, the width is 17-25 mm, average is 20.7 mm, the penis curvature is 15°-30°, average is 21.5°, and the urethral opening located on the dorsal side of the penis. The anesthesia method was selected for tracheal intubation, intravenous anesthesia combined with caudal anesthesia, and the surgical position was supine position. The surgical method: one stage of tabularized urethral plate disassembly urethroplasty: during the operation, the penile curve was corrected by free urethral plate and penile degloving. Two of them were unsatisfied with the correction of the curvature, and the ventral tunica folded was applicate. To avoid urethral plate ischemia, attention should pay to blood supply protection. The two corpus cavernosum are separated in the root, and the urethra is completely displaced to the ventral side of the cavernous body. The ventral side of the urethral under glans is shaped into a fissured that conforms to the anatomy. The prognosis and surgical choice of the midshaft epispadias were discussed combined with literature.
Result:The operation time was 130-200 min with an average of 157 mins. Intraoperative hemorrhage 5-30 ml, average is 16 ml, 1 case of glans skin was black one day after surgery, with enhanced dressing change. After 1 month, the glans was local atrophy and scar formation. No skin incision infection case. After discharge from the hospital, the follow up through the internet and outpatients for 3-40 months, average is 21 months, 2 cases with urethral fistula, more surgery to repair the fistula successfully after 6 months. The penile curvature was corrected in 8 cases, and the residual curvature of 2 cases was about 10-15°, which was temporarily observed. Patients with unilateral vesicoureteral reflux preoperatively, they still suffered from vesicoureteral reflux in the 6-12 months regular review after surgery without any intervention due to white blood cell was negative in urine routine. All cases had urinary patency and no cases with urethral stricture.
Conclusion:Tubularized urethral plate disassembly is a effective and simple procedure that can correct the midshaft epispadias in infant.
