[Early complications after robot-assisted laparoscopic radical cystectomy and their risk factors].

To identify risk factors for early complications in patients after robot-assisted laparoscopic radical cystectomy (RARC) and a standardized reporting model to predict complications precisely and recommend reasonable prophylaxis.

Methods

A total of 90 patients with bladder cancer, who underwent RARC in the Second Xiangya Hospital and the Third Xiangya Hospital of Central South University from January 2016 to January 2018, were enrolled for this study. Their clinical information, preoperative examination and follow-up data within 90 d after RARC were collected. Univariable and multivariable logistic regressions were performed to identify risk factors for early complications after RARC.

Results

The overall incidence of complications within 90 d after RARC was 48.9% (44/90), including 9 cases of Clavien grade 1, 17 cases of Clavien grade 2, 4 cases of Clavien grade 3, 12 cases of Clavien grade 4, and 2 cases of Clavien grade 5. Acute renal injury (22.2%), intestinal obstruction (16.7%), urinary tract infection (14.4%) and lymphatic leakage (10.0%) were the most common complications within 90 d after the operation. Two patients (2.2%) died within 90 d after the operation. Preoperative BMI (OR=1.16, 95% CI 1.02 to 1.32), postoperative instant (≤30 min) serum creatinine (OR=1.02, 95% CI 1.00 to 1.03), and pT stage (OR=1.67, 95% CI 1.05 to 2.68) were the risk factors for early complications after RARC.

Conclusion

The incidence of early complications after RARC is high. Preoperative hemodialysis, correction of anemia, intraoperative protection of renal function, and early recovery after surgery are helpful to prevent early complications after RARC.
