title: Laparoscopic selective clipping of upper moiety vasculature and ureter without partial nephrectomy: A novel technique for pediatric urinary incontinence due to ectopic ureter associated with poor functioning upper renal moiety.
abstract: OBJECTIVE
  The aim of this study was to present a novel laparoscopic technique for persistent urinary incontinence in pediatrics due to ectopic ureter associated with poor functioning upper renal moiety.
  
  
  METHODS
  This technique consisted of laparoscopic clipping of the upper moiety artery and vein. The ectopic ureter was also clipped afterwards without upper pole partial nephrectomy.
  
  
  RESULTS
  The patient was a seven-year-old girl with persistent urinary incontinence and confirmation of duplex kidney with poor functioning upper moiety in pre-operative investigations. The upper moiety ureter was ectopically drained to the vaginal cavity. She was immediately dry after surgery and discharged on the second postoperative day. During the follow-up period of 14 months, she was continent and symptom-free. Hydronephrosis was not visualized in follow-up ultrasonography.
  
  
  CONCLUSIONS
  This laparoscopic upper renal moiety vascular and ureteral clipping without partial nephrectomy could serve as a promising, safe and simple alternative in the treatment of patients with ectopic ureter associated with poor functioning renal moiety. Also, ipsilateral normal functioning moiety would not be associated with potential morbidity in this technique.
