Video-assisted thoracoscopic surgery after renal transplantation: A single-institution experience.

INTRODUCTION: The number of renal transplantations performed for patients with chronic kidney disease has increased in Japan, but little is known about the outcomes in those who subsequently undergo video-assisted thoracoscopic surgery (VATS). We therefore investigated the outcomes of consecutive patients requiring VATS after renal transplantation at our institute.

METHODS: We retrospectively collected the clinical data for patients undergoing VATS after renal transplantation between January 2003 and September 2014. Specifically, we compared the serum creatinine level and estimated glomerular filtration rate preoperatively and postoperatively, and investigated the postoperative complications.

RESULTS: In total, 12 patients underwent VATS after renal transplantation during the study period. All patients received two or three immunosuppressive agents. Operative methods used included VATS wedge resection (n = 4), segmentectomy (n = 4), lobectomy (n = 2), mediastinal tumor resection (n = 1), and chest wall tumor resection (n = 1). No patients required perioperative hemodialysis. There were no intraoperative complications, but one patient developed postoperative hemorrhagic cystitis and another developed pneumonia. One patient developed pneumocystis pneumonia 2 months after left lower lobectomy and required hemodialysis. No further hemodialysis was required by any patient. Of note, no statistically significant differences were observed between the preoperative and postoperative serum creatinine level (P = 0.666) and estimated glomerular filtration rate (P = 0.388). There were no in-hospital deaths. Univariate analysis revealed no significant risk factors for postoperative complications.

CONCLUSION: This report showed favorable results for VATS after renal transplantation. However, clinicians must remain vigilant for complications because transplant recipients remain permanently immunocompromised.
