About

Lingkai Cai is a pioneering urologic surgeon whose research centers on advancing minimally invasive techniques for complex upper urinary tract conditions, particularly robotic-assisted surgery. His major contributions lie in refining nephroureterectomy and renal artery aneurysm repair, demonstrating that robotic approaches can achieve radical oncologic resection while reducing patient morbidity. In his 2021 case report on robot-assisted laparoscopic retroperitoneal renal artery aneurysm repair—cited 5 times—Cai established a reproducible technique for this rare, technically demanding procedure. His 2025 study on prone retroperitoneal robotic-assisted radical nephroureterectomy (4 citations) introduced a single-position method that eliminates the need for patient repositioning, streamlining surgery for upper tract urothelial carcinoma. Cai further innovated with a modified nephroureterectomy technique using ureteral catheterization to enhance visualization during bladder cuff excision, as detailed in his 2024 work (2 citations). His 2022 case report on totally intracorporeal resection of a cutaneous ureterostomy tumor (2 citations) showcases his ability to tackle rare recurrence scenarios. With a cumulative impact of over 13 citations across these foundational studies, Cai is shaping the future of robotic urologic oncology, offering safer, more effective surgical options for patients with challenging pathologies.
