Acute kidney injury (AKI) is one of the major complications after CRS and HIPEC with concern that combining CRS and HIPEC with nephrectomy may further increase the risk of AKI. There is little published on this combined approach of CRS and HIPEC with nephrectomy for patients with disseminated appendiceal tumours. We report on eight patients who had CRS and HIPEC for an appendiceal tumour with synchronous nephrectomy. We performed a retrospective review of patients undergoing CRS and HIPEC for appendiceal malignancy and synchronous nephrectomy for renal cell carcinoma between 2014 and 2025. Patient demographics, operative details, pathology, postoperative morbidity and mortality were evaluated. A total of eight patients (M: F 4:4) with a median age of 65 were included, of which 5\/8 (62.5%) presented with abdominal pain. Concerning the primary appendiceal pathology, CRS included right hemicolectomy or extended right hemicolectomy in 5\/8 (67%). Regarding the renal pathology, 7\/8 (87.5%) had either right or left nephrectomy and 1 (12.5%) had right partial nephrectomy. The mean operation time was 453.75\u00a0minutes (365\u2013588). The mean blood loss was 1053\u00a0ml (420\u20132000). Mean Peritoneal Cancer Index was 13 (0\u201339). Complete cytoreduction was achieved in 5\/8 (62.5%). Appendix tumour pathology was low grade appendiceal mucinous neoplasm in 5\/8, goblet cell adenocarcinoma in 2\/8 and high grade appendiceal mucinous neoplasm in 1. Pathology of the renal tumour was clear cell carcinoma in 4\/8, papillary renal cell carcinoma in 3 and 1 patient with transitional cell carcinoma. Postoperative intensive care unit stay was a mean of 1\u00a0day (1\u20133). Median postoperative stay was 15\u00a0days (8\u201347). The mean drop in glomerular filtration rate was 10\u00a0ml\/min\/1.73\u00a0m2.There was no postoperative acute renal failure nor Clavien-Dindo Grade III-V complication with no post-operative mortality. Patients with synchronous appendiceal tumours and renal cell carcinoma have good immediate outcomes after combined CRS and HIPEC with nephrectomy with no measurable increase in risk of acute renal failure in this series.<\/jats:p>","DOI":"10.1093\/jscr\/rjag170","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T12:39:51Z","timestamp":1772195991000},"source":"Crossref","is-referenced-by-count":0,"title":["Cytoreductive
