Objective To evaluate the feasibility and safety of transumbilical laparoendoscopic sin-gle-site dismembered pyeloplasty ( U-LESS-P ) for the treatment of ureteropelvic junction obstruction (UPJO). Methods Between Mar.2011 and Mar.2012, U-LESS-P was performed in 8 consecutive pa-tients with UPJO by one experienced laparoscopic surgeon .The patients included 5 males and 3 females, with an average age of 28 (16-45) years.Of the 8 patients, six presented with flank pain , and two were a-symptomatic and discovered incidentally by health check .Of the 8 patients, seven had UPJO on the left side and one on the right side .The diagnosis was established by renal ultrasonography , diuretic renal scan , intra-venous urography (IVU) or/and computed tomography urography (CTU).Renal ultrasonography, IVU and ( or) CTU showed hydronephrosis and UPJO in the affected side , while diuretic renal scan demonstrated re-nal function deteriorated .No patients had undergone abdominal surgery previously .A 2-2.5 cm umbilical in-cision was made for single-port access .The procedures were performed using 30°5 mm or 10 mm laparoscope with a combination of conventional and bent laparoscopic instruments . Results All procedures were com-pleted successfully .None was converted to open surgery or traditional laparoscopic surgery .The mean opera-tive time was 153 (117-190) min, and the average estimated blood loss about 20 (10-40) ml.The mean time to resume oral diet was 1.5 days.The drainage remained 2-7 days.The mean hospital stay was 6 (4-8) days.With the follow-up of 3-6 months, symptom-free was investigated in all 8 cases.Ultrasonography , diuretic renal scan and IVU showed decreased or disappeared hydronephrosis .No operative complication , such as anastomotic stoma stenosis , was founded . Conclusions U-LESS-P is a safe and effective proce-dure for the treatment of UPJO , with the advantages of decreased operative morbidity , postoperative rapid re-covery and improved cosmetic result .

Objective:To evaluate and compare the effciency and safety of Cyberwand dual probe lithotriptor and Swiss lithoclast master in percutaneous nephrolithotomy for renal staghorn calculi. Methods:A total of 138 patients with renal staghorn calculi were divided randomly into a Cyberwand dual probe lithotripter group (Group A, n=71) and a Swiss lithoclast master group(Group B, n=67). hTe data for operative time, blood loss volume, one-stage calculus clearance rate, hospitalization time, cost of hospitalization and complication in the two groups were collected and compared. Results: The renal access was established successfully and the one-stage percutaneous nephrolithotomy (PCNL) was performed in the 2 groups. There was no significant difference in the size of stones, the age of patients and the complications between the 2 groups before the operations. Intraoperative gravel time in the Group A was signiifcantly shorter than that in the Group B (77.14±21.39 vs 84.25±20.62, P=0.049). There was no significant difference in the one-staged stone clearance rate, blood loss volume in the operation between the 2 groups. hTe one-staged stone clearance rate in the 2 groups were 67.6%(48/71) and 70.1%(47/67) respectively, with no signiifcant difference (P=0.854). Conclusion:Two lithotrities were safe and effcient for renal staghorn calculi. But comparing with Swiss lithoclast master, Cyberwand dual probe lithotriptor is more effcient and convenient.
