BACKGROUND: The aim of this study was to assess the safety and clinical effectiveness of laparoscopic disconnected pyeloplasty in treating ureteropelvic junction obstruction (UPJO) in children.
MATERIAL AND METHODS: We retrospectively analyzed the clinical data of 122 young children with UPJO treated from February 2015 to February 2018 at our hospital. According to the surgery type, the patients were divided into 2 groups: a laparoscopic surgery group (group A, n=69) and a traditional open surgery group (group B, n=53).
RESULTS: The success rate of laparoscopic disconnected pyeloplasty was 100%, and none of the patients were converted to open surgery. The mean duration of use of painkillers was 27.6±11.3 h in group A and 58.2±18.2 h in group B (p=0.012), the postoperative hospital stay was 7.8±1.5 days in group A and 11.5±2.6 days in group B (p=0.041), and the length of the incision was 1.5±0.4 cm in group A and 5.2±1.1 cm in group B (p=0.007). The incidence rate of poor surgical wound healing was 0% in group A and 7.5% in group B (p=0.020). The incidence rate of ureteral stricture was 4.3% in group A and 3.8% in group B (p=0.874) during follow-up. The 1-year follow-up showed that both the anterior and posterior diameters and glomerular filtration rate were significantly improved from the preoperation period.
CONCLUSIONS: Laparoscopic disconnected pyeloplasty to treat UPJO in young children has the same early clinical effectiveness and safety as open surgery, and this procedure has the advantages of minimal trauma, quick recovery, and good cosmetic effect.
