OBJECTIVE: To compare clinical outcomes of three dimensional (3D) and traditional two dimentional (2D) laparoscopic pyeloplasty for @entity4145 ( @entity4145 ). METHODS: Clinical data on 31 @entity1 who underwent retroperitoneoscopic pyeloplasty for @entity4145 in Peking Union Medical Hospital from January 2013 to March 2014 were retrospectively analyzed. There were 16 male and 15 female @entity1 , and the age ranged from 21 to 42 years, mean (30    6) years. The lesions of 20 cases were located on the left side and 11 cases on the right side. All cases were diagnosed as @entity4145 by B ultrasound and computed tomography urography (CTU). According to 3D or 2D laparoscopy, these @entity1 were divided into two groups. The 3D laparoscopy group included 16 cases, who received 3D retroperitoneoscopic pyeloplasty. The 2D laparoscopy group included 15 cases, who received traditional 2D retroperitoneoscopic pyeloplasty. Demographic data (gender, age, laterality, body mass index), perioperative indexes and clinical outcomes (operative time, estimated @entity190 , postoperative hospital stay, total hospitalization charge) were collected and compared between two groups.Numerical demographic and perioperative data were analyzed by using Student's t-test. Categorical data were compared using Pearson's Chi-square test. RESULTS: All operations were completed successfully without open convertion.In the 3D laparoscopy group operative time was significantly shorter than 2D laparoscopy group ((106    16) minutes vs. (124    24) minutes, t = 5.993, P = 0.021) . There were no significant difference between two groups on the estimated @entity190 ((54    14) ml vs. (57    16) ml, t = 0.285, P = 0.598), postoperative hospital stay ((7.3    0.7) days vs. (7.5    0.6) days, t = 1.415, P = 0.244), incidence of @entity260 (0/16 vs. 1/15,   (2) = 1.102, P = 0.484) and total hospitalization charge ((25 687    3 032) RMB vs. (25 426    2 626) RMB, t = 0.065, P = 0.800) . All @entity1 were followed up from 3 to 12 months (mean 6 months).Ureteropelvic junction stricture recurred in 2 cases respectively from 3D laparoscopic group and traditional laparoscopic group. Both were cured. CONCLUSIONS: 3D laparoscopic pyeloplasty is safe and feasible. Compared with the traditional 2D laparoscopic technology, 3D laparoscopy technology reduces the operation difficulty and shortens the operative time.
