Simultaneous bilateral renal pelvic tumors

Abstract

Background: A 72-year-old man was admitted with gross hematuria. Investigations revealed bilateral renal pelvic tumors. Methods/Results: Via a midline incision, left nephroureterectomy with bladder cuff resection was performed for the large left-sided tumor. The right small solitary right-sided tumor was endoscopically resected simultaneously. Histologically, both tumors were grade 2 transitional cell carcinomas without muscular invasion. Conclusion:There has been no evidence of recurrence or metastasis 30 months postoperatively.

Synchronous bilateral ureteral and renal pelvic carcinomas

“…Petkovic reported on 45 patients with bilateral tumors, but he did not separate patients with synchronous tumors from those with metachronous tumors, nor did he report tumor stages or grades; nonetheless, 71% of patients in that study were alive 5 years after diagnosis. Most case studies also report favorable outcomes, but follow‐up for these cases typically is < 2 years 2–12. The most reasonable explanation for the observation of acceptable survival is that for most patients, small, low‐grade malignancies, which permitted local resection, were present on at least one side.…”

“…Bilateral tumors are very rare and may be synchronous or metachronous. The long‐term outcome for patients with synchronous tumors is largely unknown, because our current knowledge is based primarily on approximately 30 case reports with short follow‐up 2–12. In the current report, we present clinical and histopathologic data for 15 patients with synchronous bilateral upper tract tumors.…”
