title: Transvesical laparoscopic surgery for double renal pelvis and ureter with or without ureterocele.
abstract: OBJECTIVE
  To evaluate the performance of transvesical laparoscopic surgery for patients with complete double pelvis and ureter.
  
  
  METHODS
  A total of 10 patients were included in the present study: five had complete double pelvis and ureter with ureterocele (group A), and five did not have ureterocele (group B). Three small incisions of 5 mm were used, without incision in the lower abdomen. In group A patients, the ureterocele wall was resected, and two ureters were sufficiently detached as a combined ureteral complex. Ureterocele on the side of the bladder wall was sutured to the bladder neck, and the bladder wall was strengthened. According to the cross-trigonal technique, ureterocystoneostomy was carried out in two ureters as a combined ureteral complex. In group B patients, two ureters were sufficiently detached, and ureterocystoneostomy was carried out as in group A.
  
  
  RESULTS
  In group A, the mean age was 13.4 years (range 2-34 years). The mean operation time was 304.6 min (242-346 min). In group B, the mean age was 16.6 years (range 2-48 years). The mean operation time was 207.8 min (150-249 min). There were no intraoperative and postoperative complications in both study groups.
  
  
  CONCLUSIONS
  Transvesical laparoscopic surgery can be safely and effectively used in patients with double pelvis and ureter.
