    Abstract:
    INTRODUCTION: Dismembered pyeloplasty has been the traditional technique in the management of pelvi-ureteric junction obstruction (PUJO) secondary to crossing renal vessels in children. Laparoscopic transposition of lower pole vessels for PUJO has been described in children as well as adults. CASE REPORT: We report a child with PUJO secondary to lower pole renal vessels who underwent laparoscopic transposition of vessels. The child had persistent PUJO, which was later treated with laparoscopic dismembered pyeloplasty. CONCLUSION: Laparoscopic transposition of renal vessels is a simple technique, and requires less operating time. It involves no anastomosis or insertion of temporary DJ stent. However, as of now there are no imaging techniques or intraoperative procedures available to confirm that the crossing renal vessels are the sole etiology for PUJO. This option should therefore be used with caution.
