摘要

Background

The aim of this study was to evaluate the differences in perioperative outcomes between transperitoneal and retroperitoneal techniques in cutaneous ureterostomy (CUS).

Methods

Between 2018 and 2023, 55 patients underwent CUS following robot-assisted radical cystectomy. Among the 55 patients, we compared 33 patients who underwent transperitoneal CUS (t-CUS) and 22 who underwent retroperitoneal CUS (r-CUS).

Results

Compared with the r-CUS group, the t-CUS group had significantly shorter operative times (p < 0.001); significantly less estimated blood loss (p < 0.001); and significantly lower incidence of complications (Clavien–Dindo classification grade ≤ 2) within 30 days (p = 0.005). Unexpectedly, the incidence of ileus within 30 days was lower, though the difference was not statistically significant (p = 0.064). During the median follow-up period of 24.3 months, no ileus was observed in either group after 30 days postoperatively. There was no significant difference in the stent-free rate between the groups (p = 0.449). There were also no significant differences in the rates of change in estimated glomerular filtration rate from preoperatively at 3, 6, 12, and 24 months postoperatively between the groups (p = 0.590, p = 0.627, p = 0.741, and p = 0.778, respectively).

Conclusions

Compared with r-CUS, t-CUS was associated with a shorter operative time and lower incidence of perioperative complications, including gastrointestinal complications. We believe that t-CUS can be performed safely and effectively.
