Abstract

Abstract: Objective To investigate the efficacy and outcomes of laparoscopic ureteroneocystostomy with a Boari flap(LUBF) for the treatment of middle and distal ureteral carcinoma. Methods Totally 19 cases (12 males and 7 females) of primary solitary middle or distal ureteral carcinoma in the department of urology at Beijing Chaoyang Hospital, Capital Medical University from 2005-2016 were screened and enrolled, who were treated with LUBF (5 cases treated with 2D laparoscopy,14 cases treated with 3D laparoscopy). The median age was 68.0 (60.0,75.0) years old. 12 patients were diagnosed with moderate hydronephrosis,3 patients with severe hydronephrosis. The clinical data including perioperative data, pathology results and follow-up results and collected. Results All 19 cases were completed successfully without transited to open surgery. The median operation time was 180.0 (145.0, 210.0) min. The median estimated blood loss was 50.0 (20.0,100.0) mL. The median hospital stay was 14.0 (12.0,18.0) days. The mean preoperative and postoperative serum creatinine (SCr) were(94.1±25.2)μmol/L and (88.9±32.2)μmol/L, respectively. The 1-year and 3-year overall survival were 94.4% and 82.6%, respectively. Comparing 2D and 3D methods with each other, the 3D method could be accomplished with shorter operative time (P=0.033) and less blood loss (P=0.044). Conclusions LUBF is a feasible method in treating middle and distal ureteral carcinoma, which can be accomplished with less blood loss and short operation time by a minimally invasive way. The surgery can also help improve renal function. Compared with 2D traditional laparoscopic technique, 3D-LUBF showed significant advantages in operation time and blood loss.
