Abstract
To compare perioperative and follow-up outcomes of ileal ureter replacement (IUR) among open (O-IUR), laparoscopic (L-IUR) and robotic (R-IUR) approaches.
We conducted a bidirectional cohort study of patients undergoing IUR for long ureteral strictures between September 2010 and April 2023 in our multi-institutional database. Clinical and follow-up outcomes were compared among the O-IUR, L-IUR and R-IUR groups. Clinical success was defined as symptom-free, stable renal function and no radiographic evidence of obstruction.
Among 106 patients (23 in O-IUR, 49 in L-IUR and 34 in R-IUR), the three groups had comparable demographic and baseline characteristics. The median operation time was significantly shorter in R-IUR compared to O-IUR (p = 0.029) and L-IUR (p < 0.001). The median estimated blood loss was statistically lower in R-IUR compared to O-IUR (p = 0.002) and L-IUR (p < 0.001). The median length of stay was statistically shorter in R-IUR compared to O-IUR (p < 0.001) and L-IUR (p < 0.001). The rate of postoperative Clavien-Dindo grade III complications was higher in O-IUR compared to L-IUR (p = 0.257) and R-IUR (p = 0.022).
Robotic ileal ureter replacement demonstrates clear perioperative advantages, consistent with the well-established superiority of robotic platforms in complex reconstructive procedures. However, differences in follow-up duration and potential time/experience bias should be acknowledged when interpreting complication rates.
