Analysis of Da Vinci robot-assisted laparoscopy in children’s duplication of kidney / 中华泌尿外科杂志

ABSTRACT

Objective:To investigate the efficacy of robot-assisted laparoscopic surgery in heminephrectomy in children.Methods:The clinical data of 54 children with heminephrectomy in the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2019 was analyzed retrospectively, of which 42 cases underwent laparoscopic heminephrectomy (LH group) and 12 cases underwent robot-assisted laparoscopic heminephrectomy (RALH group). In LH group, there were 17 males and 25 females, with an average age of (71.74±34.57)months, 29 on the left and 13 on the right. In RALH group, there were 4 males and 8 females, with an average age of (76.83±37.33) months, 9 on the left and 3 on the right. There was no significant difference in age, sex composition and deformity side between the two groups ( P > 0.05). The clinical indexes such as operation time, intraoperative blood loss, postoperative drainage time, hospital stay and postoperative complications were compared between the two groups. Results:There were significant differences in operation time[(196.48±21.92)min vs.(171.50±24.91)min], intraoperative blood loss[(34.14±8.63)ml vs.(18.50±5.92)ml], postoperative drainage time[6.0(5.0, 7.0)d vs. 4.5(3.0, 6.5)d] and postoperative hospital stay[(8.93±1.70)d vs.(7.33±1.37)d] between LH and RALH groups ( P < 0.05). During the follow-up from 3 months to 2 years, the lower kidneys of the two groups developed well and the symptoms before operation such as urinary tract infection, intermittent voiding leakage and dysuria caused by ureterocele were gradually relieved and disappeared after operation. In the LH group, 2 cases were complicated with the symptoms as ureteral stump effusion, cyst formation and recurrent ureteral stump infection after operation, which were cured after reoperation. There was no case of ureteral stump effusion and cyst formation in the RALH group. Conclusions:Robot-assisted laparoscopic heminephrectomy in children has shorter intraoperative blood loss, postoperative drainage time and hospital stay, lower incidence of postoperative complications, and has better efficacy and safety.
