Abstract：Objective:To summarize the preliminary experience with robot-assisted laparoscopic pyeloplasty for the treatment of recurrent obstruction after pyeloplasty in children.Methods:A retrospective study was conducted of 17 cases of recurrent obstruction after pyeloplasty in children who underwent robotic-assisted laparoscopic pyeloplasty in the Seventh Medical Center of PLA General Hospital between January 2019 and December 2023.There were 14 males and 3 females with a mean age of(6.1±0.6)years,the average weight was(18.7±1.8)kg,11 cases on left and 6 cases on right.The diagnosis and outcomes of recurrent obstruction were reviewed on clinical and imaging data.Results:All operations were successful in the 17 cases of recurrent obstruction with no serious intraoperative compli-cation.The average operative time was(78.5±10.2)min,the average intraoperative blood loss was(10.0±2.0)ml,the average start oral of feeding was(3.0±0.4)h,the average drain removal was(4.1±0.5)d,and the average postop-erative hospital stay was(7.0±1.5)d.All of the patients received postoperative follow-up ranged from 4 to 24 months,23.5% (4/17)with Clavien Ⅰand Ⅱ complications postoperatively were managed conservatively.No pa-tient suffered Clavien Ⅲ and Ⅳ complications such as anastomotic stenosis,reobstruction,or urinary tract infection postoperatively.Three months after surgery,the renal pelvis anteroposterior diameter was(1.8±0.3)cm,which was significantly smaller than that of peroperation[(3.5±0.3)cm,P<0.05],a diuretic T1/2 showed the improvement of differential renal function without urinary obstruction,and the average postoperative differential renal function was(39.7±1.8)%,which was not significantly different with peroiperation[(36.2±1.3)%,P>0.05].Conclusions:Ro-botic-assisted laparoscopic pyeloplasty is safe and effective for recurrent obstruction in children.
