[A clinical observation of cool-tip radiofrequency ablation assisted enucleation for giant renal angiomyolipoma].
Zhonghua Wai Ke za Zhi [Chinese Journal of Surgery] 2016 Februrary 2
OBJECTIVE: To initially explore the clinical effect of cool-tip radiofrequency ablation combined with enucleation for the giant hamartoma of kidney with narrow base and export-oriented way of growth.
METHODS: The clinical date of 15 patients including 6 male and 9 female with special hamartoma of kidney underwent cool-tip radiofrequency ablation assisted enucleation from July 2011 to October 2014 were reviewed.The median age was 49 years (ranging from 35 to 71 years). There were 6 cases with left renal tumor, 8 cases with right renal tumor and 1 case with solitary kidney tumor.All patients were confirmed by B ultrasound or CT scan, the mean diameter of hamartoma of kidney was 9.7 cm(8.5-12.7)cm, all tumors were located distant from the collecting system and presents with a special way of growth.The preoperative hemoglobin was (129±18)g/L, SCr was (92±41)μmol/L, glomerular filtration rate (GFR) was (32±12)ml·min(-1)·1.73 m(-2).
RESULTS: Cool-tip radiofrequency ablation assisted enucleation was technically successful in all patients.The mean operative duration was (115±31)minutes, and the average intraoperative bleeding was (72±21)ml with no blooding transfusion.The postoperative hospital stay was(7±2)days, and the postoperative hemoglobin was(129±18)g/L, SCr (92±41)μmol/L, GFR(30±15)ml·min(-1)·1.73 m(-2). No statistic change of hemoglobin and SCr or glomerular filtration rate after operations(all P>0.05). Postoperative pathology showed that all cases were hamartoma of kidney.During a mean follow-up period of 19.5 months, none of them had local tumor recurrence or chronic renal insufficiency.
CONCLUSIONS: Cool-tip radiofrequency ablation assisted enucleation is both safe and effective in the treatment of huge hamartoma of kidney with a narrow base and export-oriented way of growth. The short-term follow-up shows a satisfactory therapeutic effect.
