ABSTRACT
Objective:
To discuss the diagnosis and treatment of ectopic ureter company with the bladder neck and urethral maldevelopment in children.Methods:
The clinical data of the 6 patients admitted to Children’s Hospital affiliated to Chongqing Medical University from September 1993 to April 2019 diagnosed as ectopic ureter company with the bladder neck and urethral maldevelopment were retrospectively reviewed. The 6 children were girls and the median age was 7 years old , ranged from 2 to 15 years old. All children had ectopic ureter, including 3 in left-sided, 1 in right-sided, and 2 in bilateral-sided. Five children presented the intermittent dribbling incontinence and one child presented the continuously incontinence without normal voiding. Through ultrasound, IVP, MRI, cystoscopy and retrograde urography, seven ureters were found ectopic position, including bladder neck in 4 cases, two ureters inserted in the vagina in 2 cases. There were two cases with duplex kidney and 4 cases with renal dysplasia. Preoperative cystoscopy revealed wide and short urethra in 1 case, wide bladder neck combined with wide and short urethra in 4 cases. The surgery type included nephrectomy in cases 1-3, bilateral ureter reimplantation in case 4 who had the bilateral ectopic ureter , bilateral ureter reimplantation and bladder neck reconstruction at the same time in case 5. Nephrectomy associated with bladder neck and urethral reconstruction in case 6.Results:
Five patients were followed-up and one patient was lost to follow-up after the first operation. Mean follow-up was 41.2 months (ranging 2 to 84 months). Four patients with bladder neck and maldevelopment that were not solved intraoperatively got reoperations due to incontinence without remission. Case 1, who underwent urethral reconstruction and extension, and urinary incontinence was partially relieved. Case 2 was found to have wide bladder neck deformity, and then retrospectively got bladder neck reconstruction and urethrovaginal fistula repair in 3 years and 5 years later. The urinary incontinence was completely relieved. The ureteral stump of case 3 was resected 2 years after operation due to recurrent urinary tract infection, and then got twice bladder neck and urethral reconstruction in 3 years and 6 years later of nephrectomy. His incontinence was partially relieved. The case 4 got bladder neck and urethral reconstruction in one year after bilateral ureter reimplantation, and incontinence was partially relieved too. Among the two patients underwent combined surgery, the case 5, who got bilateral ureteral bladder replantation combined with bladder neck reconstruction, were lost to follow-up after surgery. The case 6 got dysplasia nephrectomy combined with bladder neck reconstruction and urethroplasty were completely relieved of urinary incontinence.Conclusions:
Bladder neck and urethra maldevelopment is one of the main causes of urinary incontinence after surgery in children with ectopic ureter. The diagnosis mainly relies on cystoscopy. The treatment mainly relies on surgery. Bladder neck and urethral reconstruction is expected to be available. If the operative conditions permit, synchronous surgical treatment of ectopic ureter and bladder neck and urethral maldevelopment will get a better prognosis than staging surgery.
