Bilateral renal tumours: a hard surgical problem. Case report

Area of Science:

• Urology
• Oncology
• Surgical Pathology

Background:

• Bilateral renal tumors present complex diagnostic and therapeutic challenges.
• Management strategies for synchronous bilateral kidney neoplasms require careful consideration.

Observation:

• Three cases of bilateral renal tumors were treated with varying surgical approaches.
• Preoperative biopsies showed discrepancies with final postoperative histological diagnoses in two cases.
• Intraoperative discovery of an additional renal lesion occurred in one patient.

Findings:

• Conservative surgical management, including partial nephrectomy or enucleo-resection, was employed.
• Radical nephrectomy was performed on the side with the larger tumor in two cases.
• Bilateral partial nephrectomy was necessary for tumors exceeding 5 cm.

Implications:

• Surgical intervention is essential for definitive staging and accurate histological diagnosis of bilateral renal neoplasms.
• Conservative surgical techniques preserve renal function while enabling thorough pathological assessment.
• Highlighting the limitations of preoperative biopsy in complex bilateral renal tumor cases.
