Abstract

  Long-term result of laparoscopic pyeloplasty （LPP）for ureteropelvic junction obstruction（UPJO）was investigated. Until March 2006, we performed LPP on 50 ureters in 47 patients with hydronephrosis due to UPJO. All procedures were performed transperitoneally, including Anderson-Hynes pyeloplasty, Fenger plasty, Y-V plasty and slit incisiton for 37, 10, 2 and one ureters, respectively. Seven postoperative minor complications were observed（14.6%）. During a median follow-up period of 91（58-146）months, re-stricture was observed in one ureter, which developed immediately after the stent removal. In addition, obstruction was not dissolved in two ureters. Remaining 47 ureters（94%）were regarded as success by improving symptoms and decreasing pelvic capacity associated with a patency of UPJ. Efficacy of LPP seems to be settled for long-term and, thus, LPP can be a powerful and less invasive alternative for surgical treatment of UPJO.
