OBJECTIVE: There are 2 critical steps of stent placement during laparoscopic pyeloplasty (LP) in children. Introduction to the ureteropelvic junction and passing through the ureterovesical junction. We aimed at overcoming those 2 steps by creating a modified technique. METHODS: Consecutive 27 children undergoing transperitoneal laparoscopic dismembered pyeloplasty by a single surgeon were prospectively enrolled into this study. The modifications of our technique are using an Amplatz dilator and a closed tip stent. RESULTS: The mean age of the children was 6.7 (range 4 months-17 years). The mean time of stent insertion was 2.7 ± 2.0 (2-6) min and the operative time was 128.3 ± 17.6 (90-180) min. The mean number of days of hospital stay was 2.0 ± 0.4 (1-3). After a mean follow-up period of 20.3 ± 4.2 (14-30) months, no operative failure was detected. CONCLUSION: Our modified technique is a completion of the current armamentarium for stent placement during LP in infants and children.
