One-port retroperitoneoscopic assisted pyeloplasty versus open dismembered pyeloplasty in young children: Preliminary experience

Purpose We propose 1-port retroperitoneoscopic assisted pyeloplasty as a minimally invasive approach and compare the results to open dismembered pyeloplasty. Materials and Methods All patients 6 months to 5 years old presenting with ureteropelvic junction obstruction between January 2008 and June 2009 were offered 1-port retroperitoneoscopic assisted pyeloplasty. Age matched patients who underwent open dismembered pyeloplasty during 2007 served as controls. The ureteropelvic junction was isolated retroperitoneoscopically and exteriorized through a single operative trocar. Pyeloplasty was performed in an open fashion with Double-J® stenting. Operative time, postoperative pain, surgical complications, hospital stay, ultrasound and mercaptoacetyltriglycine nuclear scan results at 6-month followup were evaluated and compared. Chi-square test and Student's t test were adopted for statistical analysis, with p
