Laparoscopic treatment of ectopic kidney with other urinary malformations in 9 children

Abstract:

Objective：To investigate the clinical features and treatment of ectopic kidney with other urinary malformations in children，and to assess the safety and effectiveness of laparoscopic treatment. Methods：The clinical data of 9 children with ectopic kidney and other urinary malformations treated with laparoscopy from October 2009 to July 2018 in Department of Urology，Children’s Hospital of Chongqing Medical University were retrospectively analyzed. Results：Ectopic kidney often occurred with other urinary malformations in children，including ipsilateral renal dysplasia（6/9），ipsilateral ureteropelvic junction stenosis（3/9），ipsilateral ectopic ureteral orifice（5/9），and urethrovaginal fistula（2/9）. Six children underwent heminephrectomy and nephroureterectomy and 3 children under－went dismembered pyeloplasty by laparoscopy. The operations were successful without conversion to open surgery. All children showed a postoperative improvement in preoperative symptoms and follow-up showed no recurrence of hydronephrosis. Conclusion：Ectopic kidney often occurs with other urinary malformations in children and it is minimally invasive，safe，and effective to treat this disease with laparoscopy.
