205 11–14 APRIL, 2018, HELSINKI, FINLAND MATERIAL AND METHODS The patient was a-13-year-old girl. She was first presented with hematuria. Ultrasonography de- tected 5 cm simple renal cyst. The cyst was rapidly increased in size up to 8 cm in a year with low back pain. DMSA showed no deterioration of differential renal function. Laparoscopic resection of renal cyst was planned. RESULTS The patient was placed lateral decubitus position, 5-mm camera port was inserted at the umbilicus and other two 5-mm trocars were introduced. After mobilization of the kidney, SAND balloon cath- eter was directly injected into an appropriate point of the distended cyst wall percutaneously under laparoscopic guide. Distal balloon was gently inflated first and proximal balloon was expanded subsequently. The cyst wall was sealed by two balloons from inside and outside then fluid was extracted without leakage. SAND balloon catheter minimized the spillage of cystic contents. It was also used as an extra working instrument. The collapsed cyst was well controlled and the cyst was excused as much as possible with electric device and withdrawn via umbilical port. The patient was discharged 4 days after the surgery and no recurrence has been noted. CONCLUSIONS SAND balloon catheter is safe and efficient tool for laparoscopic surgery which could be used for other selected cystic lesions. VD-14 (VS without presentation) LAPAROSCOPIC URETEROURETEROSTOMY FOR RETROCAVAL URETER Sonia PÉREZ-BERTÓLEZ, Oriol MARTÍN, Jenny ARBOLEDA, Andrea SORIA and Luis GARCÍA-APARICIO Hospital Sant Joan de Déu, Pediatric Urology, Pediatric Surgery, Barcelona, SPAIN PURPOSE A retrocaval ureter is a rare congenital anomaly that results from persistence of the right posterior cardinal vein in the lumbar portion, crossing anterior to the middle segment of the ureter. The aim of this video is to show the steps of a laparoscopic repair of retrocaval ureter. MATERIAL AND METHODS Case report. RESULTS A 8-year-old boy presented with progressive hydronephrosis of a solitary right kidney, with dilatation of the proximal ureter. The patient was operated on with a transperitoneal four ports approach under general anesthesia. A 10Fr Foley catheter was inserted. Patient was placed in 30º left lateral posi- tion. Open trocar placement was done at the umbilucus (5 mm), the rest 3 mm ports were placed at epigastrium, right hypocondrium and right iliac phossa. The ascending colon was reflected medially to expose the retroperitoneum. The ureter was identified coursing posterior to the inferior vena cava. Then, the proximal right ureter was dissected and mobilized. The ureter was transected and transposed anterior to the inferior vena cava, excising the retrocaval portion. The distal ureter was spatulated. A 4.8Fr double-J stent was inserted in an antegrade manner. A ureteroureterostomy was done with 5.0 vicryl by intracorporeal suturing. A closed suction drain was placed. Duration of the surgery was 100 minutes. The drain was removed after 72 hours and patient was discharged. Stent removal was done on the 2 nd postoperative month. Postoperative follow-up with ultrasound showed significant reduction of hydronephrosis.
