Abstract
In children, urologic complications are rare after laparoscopic appendectomy (LA). In this article, we report the case of a 9-year-old boy with bilateral hydronephrosis caused by ureteral calculi 10 days after he had undergone LA. The patient's urinary output normalized and renal function recovered after stone extraction and bilateral ureteral stent insertion.

Summary
Appendicitis is the most common surgical indication for acute abdomen in children; it occurs in 5.1% of all nonscheduled hospital visits It most frequently presents in patients aged 10–19 years. Bilateral ureteral stones with hydronephrosis were observed 10 days postoperatively. During follow-up at 10 days postoperatively, the patient complained of mild abdominal discomfort with poor appetite and reported vomiting twice. Bilateral obstructing stones were noted at the right ureteral orifice and left ureter, *2 cm proximal to the ureterovesical junction, resulting to severe hydronephrosis (Fig. 4). Laboratory analyses conducted on postoperative day 2 revealed a white blood cell count of 12,300 lL (range: 3500–9100 lL; neutrophilia 84.9%) and creatinine levels of 0.76 mg/dL (range: 0.70–1.30 mg/dL). The bilateral Double-J catheter was removed 1 month after outpatient follow-up, and only a mild blood clot was noted at the right ureter.
