[Retroperitoneoscopic dismembered pyeloplasty in children]

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Surgical Techniques

Context:

• Ureteropelvic junction (UPJ) obstruction is a common cause of hydronephrosis in children.
• Surgical intervention is often required to restore proper urine flow and preserve renal function.
• Traditional open pyeloplasty can involve significant morbidity.

Purpose:

• To assess the technical feasibility and clinical effectiveness of retroperitoneoscopic dismembered pyeloplasty in pediatric patients.
• To evaluate the safety and outcomes of this minimally invasive approach for UPJ obstruction.

Summary:

• Seventeen children (aged 3-10 years) with symptomatic UPJ obstruction underwent retroperitoneoscopic dismembered pyeloplasty.
• The procedure was successful in all cases with no major complications. Average operative time was 4.3 hours, blood loss 38 ml, and hospital stay 4.6 days.
• Postoperative follow-up showed complete resolution of obstruction in all patients, with only one instance of urine leakage.

Impact:

• Retroperitoneoscopic dismembered pyeloplasty demonstrates excellent short-term and mid-term efficacy for pediatric UPJ obstruction.
• This minimally invasive technique offers a safe and effective alternative to open surgery, potentially reducing patient recovery time and morbidity.
