Summary

A 72-year-old man with bilateral renal pelvic tumors underwent successful treatment. Both tumors, diagnosed as grade 2 transitional cell carcinomas, showed no recurrence or metastasis at 30 months post-surgery.

Area of Science:

  • Uro-oncology
  • Surgical oncology
  • Nephrology

Background:

  • A 72-year-old male presented with gross hematuria, indicating a potential urinary tract malignancy.
  • Diagnostic investigations confirmed the presence of bilateral renal pelvic tumors, necessitating prompt clinical evaluation and management.

Observation:

  • The patient presented with gross hematuria, a significant clinical sign.
  • Bilateral renal pelvic tumors were identified, posing a complex diagnostic and therapeutic challenge.

Findings:

  • Surgical intervention included left nephroureterectomy with bladder cuff resection for the larger left-sided tumor.
  • Simultaneous endoscopic resection was performed for the smaller right-sided tumor.
  • Histopathological analysis revealed both tumors as grade 2 transitional cell carcinomas, crucially without evidence of muscular invasion.

Implications:

  • This case highlights the successful management of bilateral renal pelvic tumors with a combined surgical and endoscopic approach.
  • The absence of recurrence or metastasis at 30 months postoperatively suggests favorable outcomes for this treatment strategy in select cases.
  • Further research into optimal management strategies for synchronous bilateral upper tract urothelial carcinomas is warranted.
