Treatment outcomes of laparoscopic partial nephrectomy for cT1bN0M0 renal cell carcinoma at Binh Dan Hospital
Tóm tắt
Introduction: This study aims to evaluate perioperative, oncological, and functional outcomes of laparoscopic partial nephrectomy performed for cT1bN0M0 renal cell carcinoma at Binh Dan Hospital.
Materials - Methods: Data were collected on 37 patients who had undergone laparoscopic partial nephrectomy for cT1bN0M0 renal cell carcinoma from January 2021 to September 2023. Demographic, radiological growth patterns of the tumors and intraoperative data were collected. Post-operative complications and pathological data were also recorded. Patients were followed for an average of 13.6 months to review oncological and functional outcomes.
Results: Radiological tumor size was 48.1 ± 8.2 mm. The average operative time was 157.4 ± 55.3 minutes. The mean estimated blood loss was 213.4 ± 239.8 ml. Warm ischemia time (WIT) was 20.3 ± 7.7 min. Pathological analyses revealed renal cell carcinoma in 37/37 patients and positive margins in 2.7% of cases. 37/37 cases (100%) had no local recurrence with a minimum follow-up time of 6 months. Warm ischemia time (WIT) was associated with acute kidney injury (AKI) with a rate of 4.5% if WIT was shorter than 20 minutes. This rate was 26.7% in the WIT longer than 20 minutes group.
Conclusion: This survey confirms that laparoscopic partial nephrectomy for cT1bN0M0 renal cell carcinoma is feasible in experienced hands with reasonable oncological and functional outcomes.
