Surgical treatment of UPJO with pyelonephrosis in children

In 2022, we treat 2 children with hydronephrosis and pyonephrosis, 1 with primary ureteropelvic junction obstruction and 1 with recurrent obstruction after laparoscopic pyeloplasty.All children have purulent pyelonephritis and urinary abdomen. After comprehensive anti-infection+abdominal drainage +renal pelvis drainage, the infection was significantly improved, and they were cured and discharged after pyeloplasty under general anesthesia. Conclusion: UPJO complicated with pyonephrosis in children is rare, and the most important treatment principle for hydronephrosis complicated with pyonephrosis is adequate drainage. Comprehensive anti-infection + open drainage infection treatment and control followed by conventional pyeloplasty can cure as soon as possible and return to normal life.It has the advantages of good safety effect and easy promotion.
