Preoperative Renal Tumor Embolization

Abstract

The medical reports of 113 patients operated upon for renal tumors were retrospectively reviewed to assess the value of preoperative embolization. Coils or ethanol were used preoperatively in 55 patients while 58 patients underwent nephrectomy without embolization. The tumors were staged according to the TNM and the Robson staging classification. TI and T2 tumors as well as T3 and T4 tumors were grouped together for statistical evaluation. There was no significant difference in intraoperative blood loss, operation time and survival rate between patients undergoing preoperative embolization and those who had only nephrectomy. Duration of hospital stay was always longer in the preoperatively embolized group. Preoperative embolization of renal tumors neither improved the patients' outcome nor reduced the surgical risk. Robson's classification, stage III/IV, did not show any significant differences for embolized patients or for those nephrectomized without embolization.

Indocyanine green‐marked fluorescence‐guided off‐clamp versus intraoperative ultrasound‐guided on‐clamp robotic partial nephrectomy: Outcomes on surgical procedure

“…Moreover, some studies have questioned the utility of preoperative RCC embolization, with no significant difference in intraoperative blood loss and operative time compared to PN without embolization. 24 However, embolization may become a useful tool to help the localization of the renal mass. Accordingly, our study aims to compare surgical and functional outcomes between off‐clamp RAPN with ICG tumour marking through preliminary selective RCC embolization and on‐clamp RAPN with IUS‐only identification.…”

Transcatheter Renal Interventions: A Review of Established and Emerging Procedures

“…Similar to AMLs, safe injection of liquid sclerosants or embolic particles may require balloon occlusion or selective injection via a microcatheter. Renal artery embolization may also have a limited role in the palliative setting;[ 43 ] a recent report described radioembolization with yttrium-90 glass microspheres for palliative treatment of RCC in an 87-year-old woman with a 14.7 × 11.1 cm left renal mass, in which the mass remained stable in size and the patient reported decreased pain and hematuria during the first year following treatment.

Embolisation of cancer: what is the evidence?

“…A subsequent series by Bakke et al [ 54 ] showed no difference in survival of patients with stage 4 renal cell carcinoma treated with embolisation/nephrectomy and embolisation alone. Fischedick et al [ 55 ] also found no survival benefit of embolisation prior to nephrectomy, and demonstrated no difference in peri-operative blood loss during nephrectomy between patients who received embolisation and those who did not. The failure of embolisation to reduce peri-operative blood loss was also seen in further series of 35 patients treated with embolisation with ethanol [ 56 ].…”
