OBJECTIVE: To report our experience of laparoscopic heminephroureterectomy (Hnu) in pediatric patients with duplex anomalies, in comparison to open surgery. PATIENTS AND METHODS: Retrospective review of data from patients who underwent Hnu from 2005 to 2008 was performed. The patients were divided into two groups: laparoscopic (LHnu) and open surgery (OHnu). Laparoscopic surgery was performed by transperitoneal approach in majority of cases. Open surgery was performed by retroperitoneal approach in all cases. RESULTS: Group LHnu: nine patients (8 females, 1 male) with median age of 14 months (range 3-205). Transperitoneal approach was performed in eight patients. Mean operative time was 182 min (CI 95% 146-217). No conversion to open surgery was necessary and there were no complications. Mean hospital stay was 2.44 days (CI 95% 1.37-3.52). Group OHnu: eight patients (3 females, 5 males) underwent nine heminephrectomies at median age of 6.9 months (range 1-12). Mean operating time was 152 min (CI 95% 121-183). There were no complications and mean hospital stay was 4.38 (CI 95% 2.59-6.16) days. Statistical analysis showed no statistically significant difference (P>0.05) in operating time between groups while mean hospital stay was significant (P=0.021). CONCLUSION: The laparoscopic approach is feasible, safe, reduces hospital stay, does not increase operating time and has better cosmetic results. We believe this should be the first option for heminephrectomy.
