ABSTRACT

Objective:

To explore the feasibility and precautions of laparoscopic pyeloplasty for children with hydronephrosis combined with renal trauma.

Methods:

The clinical data of 6 cases with hydronephrosis and renal trauma admitted to the Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from August 2016 to August 2019, aged from 5 to 11 years old (average age 7 years old) were reviewed.These patients had suffered renal trauma for 1 to 4 days.All patients had the symptoms of pain in the affected kidney, and 4 patients had hematuria.The renal pelvis diameter of all patients was more than 25 mm.The patients underwent laparoscopic pyeloplasty and renal rupture repairment, with the ureteral stent, perirenal drainage tube and catheter placed inside the body during the operation.

Results:

All operations were completed successfully without any blood transfusion and open surgery.Intrao-perative time was from 2.5 to 3.5 hours.Two cases had renal parenchymal contusion in the front lower pole of kidneys and 4 cases in the lateral lower pole.Five cases had renal cortex and pelvis rupture, and 1 case had renal cortical fracture and subcapsular hematoncus.After the operation, the perinephric drainage tube was pulled out in 3 to 5 days, the catheter was pulled out in 7 to 10 days, and the ureteral stent was removed in 6 to 8 weeks.All children recovered well and hydronephrosis was ameliorated.The glomerular filtration rates and fractional renal function were all improved.

Conclusions:

One stage laparoscopic pyeloplasty is safe and effective for the treatment of hydronephrosis with renal trauma in children.Renal trauma in children usually occurs at the lower pole of the kidney.Early operation is needed if hydronephrosis is aggravated and symptoms are not relieved after the trauma.Intraoperative impairment of renal parenchymal rupture can be conducted.For intraoperative bleeding in grade 3 renal injury, renal parenchyma suturation and removal of necrotic renal tissue should be adopted to arrest bleeding.
