BACKGROUND: The aim of this study was to assess the efficacy of laser endopyelotomy in both primary and secondary ureteropelvic junction obstructions (UPJOs).
METHODS: Primary category consisted of 10 patients of congenital UPJOs. Secondary category was comprised of UPJOs in 12 status post pyeloplasty, 10 status post lithotomy, 5 status post shockwave lithotripsy, and 10 status post ureteroscopic lithotripsy. Holmium:Yttrium-Aluminium-Garnet (Ho:YAG) laser endopyelotomy was performed in all subjects. Exclusion criteria included obstructions longer than 2 cm, ipsilateral upper urinary calculi and crossing vasculature.
RESULTS: Mean operation time was 44 min. Average inpatient duration was 1.87 days. No major complication occurred. Follow-ups were at least 12 months. Success rate for single endopyelotomy was 82.5%, leaving 7 patients for a secondary endopyelotomy. Secondary UPJO due to failed pyeloplasty had a predilection of restenosis after endopyelotomy (P=0.0005) compared to other etiologies.
CONCLUSIONS: Ho:YAG laser endopyelotomy is a safe and effective approach effective in both primary and secondary UPJO treatments.
