Clinical analysis of conventional laparoscopic and robotic-assisted laparoscopic pyeloplasty in children

摘要

Objective To compare the effect and scope of conventional laparoscopic and robotic-assisted laparoscopic pyeloplasty in children. Methods A retrospective study was performed in children undergoing conventional laparoscopy and robotic assisted laparoscopic pyeloplasty from January 2014 to May 2016. All patients underwent dismembered pyeloplasty (Anderson-Hynes). Results A total of 39 patients of ureteropelvic junction obstruction (UPJO) were enrolled,. There were 20 boys and 4 girls. And laparoscopy (LP, 14 boys versus 1 girl) and robotic surgery (RALP, 14 boys versus 1 girl) were performed. The mean age was 3.2 (LP) vs. 7.5 (RALP) years, mean operative duration was 167 (LP) vs. 173 (RALP) min, the mean estimated blood loss 15 ml and the mean follow-up period 22.3 (LP) vs. 17.5 (RALP) months. The procedure was performed without any conversion into open surgery. There was no onset of perioperative complications. There was recurrence in each group. Conclusions Robotic assisted laparoscopic pyeloplasty may be safely performed in children aged over 3 years with a similar efficacy to that of traditional laparoscopy.
