Background: To compare the return of bladder function and genitourinary complications after type Cl robotic nerve-sparing radical hysterectomy (C1-RRH) to type C2 robotic radical hysterectomy (C2-RRH) in gynecologic cancers. Methods: A retrospective analysis between C1-RRH (n = 42) and C2-RRH (n = 43) was performed. Operative outcomes and perioperative genitourinary complications between the two groups were analyzed. Results: The C1-RRH group had shorter hospitalization (0.7 vs. 1.7 days, p < 0.001) and shorter DUC (1 vs. 28 days, p < 0.001). About 76% of C1-RRH group required a catheter for less than 1 week while 84% of the C2RRH group did for more than 1 week (54% for 1-6 weeks; 30% > 6 weeks). In spite of the short stay after surgery (95% of C1-RRH <= 1 day), only two patients (4.8%) in C1-RRH group were admitted again because of urinary tract infection. C1-RRH was only independent predictor for early bladder function return within 1 week after surgery. Conclusion: The C1-RRH showed early bladder function return and feasible outcomes in spite of early discharge. It can be considered as the first surgical option in gynecologic cancer patients who need RH to preserve their bladder function.
