Frequently associated with duplex kidney, pediatric bilateral orthotopic single system ureteroceles are a very uncommon condition. The aim of this video is to show a clinical series of pediatric patients with bilateral ureteroceles, successfully treated by an endoscopic route. MATERIAL AND METHODS Retrospective reviews of patients treated between 2011 and 2016. A total of 7 male patients were identified. 5 patients had antenatal hydronephrosis and postnatal studies had confirmed bilateral single system ureteroceles. Cases six and seven presented with acute pyelonephritis at age of 1 month and 2 years respectively. All patients were studied with ultrasonography and renal scintig- raphy. Four had pre operative micturating cystourethrogram. RESULTS An endoscopic treatment was offered due to infection, progressive hydronephrosis and/or obstruc- tive pattern at the renal scintigraphy. Eleven consecutive endoscopic punctures were performed at a median age of 9 months (range 2–27). In five patients bugbee diathermy was used. As shown in this video we have recently incorporated the Holmium Laser technology for the puncture. This technique is easy to reproduce and offers a more controlled ureterocele incision. After a mean 22 months (6–44) follow up, no complications were observed and all patients remain asymptomatic without use of antibiotics and with resolution of the hydronephrosis. CONCLUSIONS Bilateral pediatric single system ureterocele is a very rare condition. This video demonstrated suc- cessful endoscopic minimal invasive treatment in a consecutive series of seven patients. Holmiun Laser ureterocele cut offers an easy to perform technique with good outcomes.
