The first robotic-assisted kidney transplant (RAKT) in the Philippines was performed at St Luke’s Medical Center Global City in December 2023. This milestone marks a significant advancement in kidney transplantation within the country. This case series provides the first documentation of the preliminary clinical outcomes of RAKT in the Philippines.

We conducted a retrospective analysis of five (N=5) recipients who underwent living donor robotic-assisted kidney transplantation from December 2023 to March 2025 at St. Luke’s Medical Center, Global City. Data were gathered from the Center for Organ Transplant Registry, with follow-up extending until April 2025. The variables collected included demographics, primary kidney disease, donor relationship, HLA mismatch, dialysis modality and duration, BMI, warm ischemia time, hospitalization length, and post-operative outcomes.

The mean recipient age was 42.2 years (range: 19-63 years), with 60% (n=3) being male. The primary kidney diseases were diabetic kidney disease, polycystic kidney disease, and chronic glomerulonephritis. Two patients underwent preemptive transplantation, while three were on maintenance hemodialysis. Two patients had living-related donors. The BMI of recipients ranged from 17.73 to 59.04, with two patients classified as morbidly obese (BMIs 43.04 and 59.04). Warm ischemia time ranged from 76.8 to 151.8 minutes. The median hospitalization duration was 9 days (range: 6-17 days). All patients demonstrated a significant decline in serum creatinine levels post-transplant, with adequate urine output and stable allograft function throughout the follow-up. No episodes of delayed allograft function, acute rejection, readmission, graft loss, or mortality were observed during the study period.

Robotic-assisted kidney transplantation represents a promising advancement in kidney transplantation, and the early outcomes in this initial case series are encouraging, showing good allograft function and minimal complications. It may serve as a viable alternative to open surgery, especially for morbidly obese patients who face higher surgical risks. Further studies with larger cohorts are warranted to validate these findings and assess safety and efficacy of robotic-assisted surgery, ultimately improving kidney transplantation outcomes in the Philippines.
