title: Case report: radiofrequency ablation-induced renal-pelvic obstruction resulting in nephrectomy.
abstract: Radiofrequency ablation (RFA) has emerged as a minimally invasive nephron-sparing treatment for small (<4-cm) renal tumors. Post-RFA complications have been reported. We describe a patient who developed complete renal-pelvic obstruction after RFA. To our knowledge, this is the first such case to be reported and the second reported renal-unit loss as the result of collecting-system obstruction after RFA.
