Transperitoneal laparoscopic nephrectomy for renal tumour disease versus non-tumour disease: What are the differences in outcomes?

ABSTRACT

@#Introduction: Laparoscopic nephrectomy is the standard of care for the removal of both non-functioning and tumourbearing kidneys. This study was conducted to compare the characteristics and outcomes follow-ing laparoscopic transperitoneal nephrectomy (TP) for tumour and nontumour disease. Methods: We retro-spectively reviewed all TP nephrectomies performed in the Hospital Sultanah Bahiyah Alor Setar, Kedah between January 2016 and July 2017. Results: A total of 36 eligible cases were identified, 10 of which were for renal tumours and the others for nonfunctioning kidneys. There were no statistically significant differ-ences between the two groups in terms of demographics and comorbidities. We also did not identify any sta-tistically significant differences between the two groups in terms of operating time, blood loss, need for transfusion, septic complications and postoperative recovery. The only significant difference between the groups was the postoperative rise in serum creatinine, which was higher in the tumour disease group (mean rise 23.4 vs 5.35µmol/l; p = 0.012). Conclusions: Our study showed that laparoscopic nephrectomy is both feasible and safe for the treatment of tumour and non-tumour renal disease with low complication rates in both groups.
