Abstract

Objective: To evaluate the long-term outcomes of one-trocar retroperitoneoscopic-assisted pyeloplasty in treating ureteropelvic junction obstruction (UPJO) in children under 5 years of age. Subjects and Methods: a retrospective study of 70 patients under 5 years old diagnosed with UPJO who underwent one-trocar retroperitoneoscopic-assisted pyeloplasty January 2011 and June 2013 at the Department of Urology, National Children's Hospital. All patients underwent routine blood tests and preoperative imaging to assess the degree of obstruction and kidney function. Preoperative data including age, sex, clinical presentation, anteroposterior diameter of the renal pelvis, and renal function from renal scintigraphy were recorded. Early postoperative outcomes were evaluated at 6 months Long-term outcomes were evaluated at an average of 65 months postoperatively (ranging from 36 to 120 months). Results: Among the 70 children who underwent surgery, 65 were male (92.86%) and 5 were female (7.14%), with ages ranging from 1 month to 5 years (average age 22.9 ± 18.6 months). The mean preoperative renal pelvis diameter was 34.3 ± 8.1 mm (range: 25–50 mm). Laparoscopic surgery was completed in 68 out of 70 patients (97.2%). Two cases (2.8%) required conversion to open surgery due to peritoneal perforation. The average operative time was 74.8 ± 15.2 minutes (range: 45–100 minutes). The average hospital stay was 3.7 ± 2.6 days.. Among the 68 patients who underwent successful laparoscopic surgery, 51 (75%) had follow-up data at 6 months; 17 (25%) were lost to follow-up. The average postoperative renal pelvis diameter was 14.3 ± 5.1 mm. 45/51 (88.3%) patients had a renal pelvis diameter <15 mm, 4/51 (7.8%) had diameters <25 mm, and 2/51 (3.9%) required reoperation due to anastomotic stricture. Long-term outcomes were evaluated in 30/51 patients with a mean follow-up of 65 months (range: 36–120 months). 28/30 patients had good outcomes. Conclusion: One-trocar retroperitoneoscopic-assisted pyeloplasty is an effective and suitable surgical treatment in children under 5 years old.
