Intraoperative and Early Post‑Transplant Assessment in Kidney Transplantation

Guideline Recommendations (European Association of Urology)

The 2024 EAU guidelines do not give a specific recommendation to assess urine output after graft reperfusion and before completing the ureteral anastomosis; they focus on overall surgical technique instead. 1
The EAU emphasizes meticulous bench preparation, urging preservation of the ureter’s quality and the peripelvic / proximal periureteral “golden triangle” tissue to protect ureteral perfusion. 2
According to the EAU, surgeons should verify the intima of donor and recipient arteries before starting the arterial anastomosis to avoid intimal rupture or flaps. 1
The EAU recommends careful peri‑ and postoperative fluid balance as essential for optimal renal graft function. 2

Preservation of the ureteral blood supply during dissection—specifically maintaining the peripelvic and proximal periureteral tissue (“golden triangle”)—is critical to prevent ureteral ischemic complications. 1

Complication	Reported Incidence Range	Typical Etiology (when noted)
Urinary leakage	0 % – 9.3 %	Linked to ureteral ischemia and technical factors.
Ureteral stenosis	0.6 % – 10.5 %	Early (< 3 months) stenosis usually stems from surgical technique or compromised ureteral blood supply.
Arterial thrombosis (absence of urine output)	0.5 % – 3.5 %	Indicates possible vascular occlusion.
Venous thrombosis (absence of urine output)	0.5 % – 4 %	Indicates possible vascular occlusion.

Incidence data are drawn from European Urology publications referenced in the EAU guideline context. [3] [4] 5

If no urine is produced after reperfusion, an immediate color Doppler ultrasound should be performed to evaluate for arterial or venous thrombosis. 3
