Ureteric Clipping for the Treatment of Urinary Incontinence in Girls With Ectopic Ureters: Predicting Who Is Going to Dilate and Does It Matter?

OBJECTIVE To assess the effectiveness and midterm follow-up of laparoscopic upper pole ectopic ureteral clipping to treat urinary incontinence in girls with duplex kidneys and non/poorly functioning upper pole moieties. To see if preoperative characteristics increased the likelihood of significant postoperative dilatation and whether this dilation has clinical significance. METHODS A database review identified children who had undergone ureteric clipping at our institution. Patient details assessed included: age at presentation, age at procedure, significant past medical history, preoperative investigations, operative time, length of stay, postoperative symptoms, postoperative renal tract ultrasound findings and the need for subsequent intervention. RESULTS Six girls underwent clipping between March 2018 and May 2021. The mean age at presentation and surgery were 77 months (39-186) and 86 months (44-193), respectively. The mean operative time was 94 minutes (range 66-128 minutes). The median length of stay was 1 day (range 0-3 days). All the girls were dry immediately after the procedure. During a mean follow-up of 51 months (29-66) all children have remained symptom-free and required no further intervention. Two children have developed significant (> 30 mm) but stable ureteric dilatation after clipping but have remained asymptomatic and therefore are continuing on conservative followup. Both these children had dilated ureters (> 10 mm) preoperatively. CONCLUSION Ureteric clipping is quick, safe, and effective option in dealing with incontinence due to ectopic upper pole ureters in girls. Children with preoperative ureteric dilation seem to be at increased risk of postoperative dilation. However, as they remain asymptomatic, the clinical significance of this dilatation is unclear.
