# Robot-assisted laparoscopic simultaneous bilateral partial nephrectomy for bilateral renal carcinoma: a case report

## TL;DR

A 38-year-old man with bilateral kidney tumors underwent robot-assisted surgery to remove both tumors while preserving kidney function.

## Contribution

The paper presents a case of robot-assisted laparoscopic simultaneous bilateral partial nephrectomy for sporadic bilateral renal carcinoma.

## Key findings

- Robot-assisted surgery achieved favorable outcomes in a patient with bilateral renal tumors.
- Simultaneous bilateral partial nephrectomy is a viable option with improved surgical techniques.
- Surgical decisions should consider tumor stage and R. E. N. A. L. nephrometry score.

## Abstract

Renal carcinoma is one of the most common malignant tumors of the urinary system, with more than 400,000 new cases diagnosed worldwide each year. More than 90% of cases involve unilateral tumors, whereas sporadic synchronous bilateral renal carcinoma (sBRC) accounts for only 1–5% of patients.

A 38-year-old male patient was admitted to Affiliated Hospital of Hebei University with a 5-day history of bilateral renal masses detected during a routine health examination. The patient with sporadic sBRC using robot-assisted laparoscopic simultaneous bilateral partial nephrectomy via a retroperitoneal approach. The procedure achieved favorable clinical outcomes.

With the advancement of robotic surgery and improvements in surgical expertise, simultaneous bilateral partial nephrectomy has emerged as a viable alternative. Surgical decision-making must consider tumor stage and R. E. N. A. L. nephrometry score.
