Abstract:
Objective To evaluate the efficacy and safety of robot-assisted laparoscopic pyeloplasty(RALP)in the treatment of obstructive hydronephrosis at ureteropelvic junction in infants≤6 months old.Methods Clinical data of 44 infants with ureteropelvic junction obstruction(UPJO)and hydronephrosis treated by RALP from January 2021 to December 2023 were analyzed retrospectively.The average age was(72.3±49.7)d(range,5 d-6 months old),and the average weight was(5.7±1.6)kg(range,2.9-8.5 kg).Preoperative ultrasonography showed that the anteroposterior diameter was(30.2±9.5)mm and the thinnest part of the renal parenchyma was(2.6±1.2)mm.By using the da Vinci Xi robotic operating system,the narrow segment of the ureteropelvic junction was fully exposed,the renal pelvis and ureter were trimmed with scissors,and the ureter was anastomosed with 6-0 single strands.Results All the 44 operations were completed successfully without conversion to traditional laparoscopic or open surgery.No intraoperative complications occurred.The operation time was 105-245 min(mean,179.8 min),and the intraoperative blood loss was 2-10 ml(mean,4.9 ml).Re-examinations of ultrasonography at 6 months after removal of double J tube showed that the anteroposterior diameter was(10.5±6.3)mm,which was significantly decreased than that before operation(paired t test,t=19.985,P=0.000),and the thinnest part of the renal parenchyma was(6.8±1.7)mm,which was significantly increased than that before operation(paired t test,t=18.420,P=0.000).The patients were followed up for 6-12 months after removal of double J tube.There were no complications such as anastomotic stricture,urine leakage,or recurrence of obstruction.Conclusion RALP is safe and effective in the treatment of UPJO and hydronephrosis in infants younger than 6 months old.
