ABSTRACT
PURPOSE:
To report one of the largest series of clinical and renal function outcomes of treated iatrogenic vascular lesions (IVL) after partial nephrectomy (PN). Angioembolization (AE) is the treatment of choice for patients with these lesions, but the additional renal injury conferred by this treatment has not been well described. PATIENTS ANDMETHODS:
Patients who underwent open, laparoscopic, or robot-assisted PN from 2002 to 2012 were identified and those with AE were selected. Patients' charts were reviewed, and renal function was analyzed using estimated glomerular filtration rate (eGFR) and progression of chronic kidney disease (CKD) classification before and after PN and AE.RESULTS:
There were 849 patients who underwent PN and an IVL developed in 28 (3.3%). Twenty (71%) presented with gross hematuria at a mean of 10.2 ± 7.7 days after PN and 8 (28%) needed transfusion. All patients had identifiable IVL at the time of selective AE, and technical success was achieved in 24/28 (86%), although 4 needed subsequent additional AE. The paired decrease in eGFR after PN was significant (P<0.01), while the paired change in eGFR after AE was not with either short-term (2.8 days) or intermediate-term (362 days) follow-up (P=0.50). Four patients experienced transient worsening in CKD classification after AE, although three experienced CKD stage improvement.CONCLUSION:
Selective AE for IVL after PN is safe, efficacious, and does not lead to a significant impairment of renal function. It remains the preferred approach for the evaluation and management of post-PN hemorrhage.
