ABSTRACT
Objective To explore the feasibility and safety of laparoscopic pyeloplasty in the treatment of neonatal renal pelvis ureteraljunction obstruction(PUJO),and to analyze its preliminary experience.Methods From Jun.2009 to Apr.2012,11 neonates(9 boys and 2 girls) were recruited in this study.They were all detected by prenatal ultrasound and renal pelvis anteroposterior diameter was more than 3 cm.One week after birth,emission computed tomography(ECT) showed that split function of hydronephrotic kidneys were lower than 40％.All patients underwent laparoscopic dismembered pyeloplasty.Results All successful underwent laparoscopic dismembered pyeloplasty,no conversion to open surgery or additional Trocar,no intraoperative complications.The mean time of operation was 80 min,and blood loss was less than 10 mL,the mean postoperative hospital stay was 9 days.All patients were followed up for 6 to 36 months with ultrasound and ECT.The thickness of renal parenchyma increased,and 8 kidneys turned almost normal,the other's renal pelvis anteroposterior diameter was about 1.5 cm,renal pelvis anteroposterior was significantly reduced,and the scar was not obvious.Conclusions Laparoscopic ureteroplasty in the treatment of neonatal hydronephrosis is safe and feasible,and it is worthy of application in a large scale.Qperators need mastering laparoscopic suture technology,and then apply the technique from older children to neonates gradually.
