Abstract
OBJECTIVE: To describe the use of renal angiography in the detection of renal vascular injuries following percutaneous nephrolithotomy and to assess the efficacy of endovascular management of these complications.
MATERIALS AND METHODS: This was a retrospective review of 159 consecutive patients over a period of 12 years from 2005 to 2016 who presented with significant post nephrolithotomy hemorrhage and who were evaluated by renal angiography as a first-line diagnostic study, followed by embolization of identified renal vascular injuries in the same session. The parameters assessed for each patient included type of renal vascular injury identified, type of embolic material and therapeutic outcome.
RESULTS: Renal vascular lesions identified in 119 patients were treated with embolization with complete resolution of hemorrhage, no further clinical deterioration and preservation of renal function.
CONCLUSIONS: Renal vascular injury is a rare complication of percutaneous nephrolithotomy. Early renal angiography and selective embolization can play an integral diagnostic and therapeutic role.
