Article Title: Outcomes of patients with surgically treated bilateral renal masses and a minimum of 10 years of followup
Abstract: PURPOSE: Nephron sparing surgery has been advocated for patients with bilateral renal masses but long-term functional and oncological outcomes are lacking. We report the outcomes of patients with bilateral renal masses and a minimum 10-year followup. MATERIALS AND METHODS: Patients with bilateral renal masses evaluated at our institution who were treated with initial surgery at least 10 years ago and underwent interventions on each renal unit were included in the analysis. Collected data included demographics, hereditary diagnosis, number of renal interventions, renal function and mortality status. Overall and renal cell carcinoma specific survival was assessed. Comparisons were made of renal function and overall survival between groups with 2 renal units and a surgically solitary kidney. RESULTS: A total of 128 patients met study inclusion criteria. Median followup in our cohort was 16 years (mean 17, range 10 to 49). The median number of surgical interventions was 3 (range 2 to 10). Of the patients 87 (68%) required repeat interventions on the ipsilateral renal unit at last followup with a median of 6.2 years (range 0.7 to 21) between interventions. Overall and renal cell cancer specific survival was 88% and 97%, respectively. Six patients (4.7%) ultimately underwent bilateral nephrectomy. Although renal function was better preserved in patients with 2 kidneys (70 vs 53 ml/minute/1.73 m(2), p = 0.0002), there was no difference in overall survival between those with bilateral kidneys or a surgically solitary kidney. CONCLUSIONS: At a minimum 10-year followup after initial surgery, nephron sparing surgery allowed for excellent oncological and functional outcomes. Despite the need for repeat surgical interventions, nephron sparing surgery enabled dialysis to be avoided in more than 95% of patients.
