To analyze the impact of urinary diversion type following radical cystectomy (RC) on readmission and short-term mortality rates.
Patients who underwent RC for bladder cancer in the National Cancer Data Base were grouped based on the type of urinary diversion performed: non-continent [ileal conduit (IC)] or two continent techniques [continent pouch (CP) and orthotopic neobladder (NB)]. We used propensity score matching and multivariable logistic regression models to compare 30-day readmission and 30- and 90-day mortality between the different types of urinary diversion.
Among 11,933 patients who underwent RC, we identified 10,197 (85.5%) IC, 1044 (8.7%) CP, and 692 (5.8%) NB. Patients who received IC were significantly older and had more comorbidities (p < 0.0001). Continent diversions were more likely to be performed at an academic center (p < 0.0001). Surgery performed at a non-academic center was an independent predictor of 30-day readmission (OR 1.19, p = 0.010) and 30-day mortality (OR 1.27, p = 0.043). Patients undergoing NB had an increased likelihood of being readmitted (OR 1.41, p = 0.010). There was no significant difference in short-term mortality between groups.
Patients undergoing NB had marginally increased rates of readmission compared to IC. Surgery performed at a non-academic center was associated with higher readmission and 30-day mortality. Similar short-term mortality rates were observed among the different types of urinary diversion.
