A new operative technique for a rare case of pyelic fusion.

This case report presents the first documented case of pyelic fusion with two sites of obstruction. The patient was diagnosed following antenatal presentation and the operative technique described in this case report is the only way by which the obstructions could be treated with a single procedure. The left pelvicalyceal system was grossly dilated and was draining into the common pelvis via an obstructed calyx in the isthmus of the horse shoe. The common ureter also had a pelviureteric junction stenosis. Incisions were made in the left dilated pelvis and in the obstructed part of the pelviureteric junction and ureter. The two openings were sutured as a culp pyeloplasty using interrupted 6/0 PDS sutures over a 4F JJ stent.
