Objective and Subjective Assessment of Bladder Function after Robot-assisted Laparoscopic Radical Hysterectomy for Early-stage Cervical Cancer.

Study Objective: To examine whether objective bladder function after robot-assisted radical hysterectomy (RRH) for early-stage cervical cancer is correlated with subjective patient-reported outcomes and quality of life during the first year after RRH.
Design: Prospective observational study.
Setting: Karolinska University Hospital, Sweden.
Patients: Women with early-stage cervical cancer (International Federation of Gynecology and Obstetrics stage IA2-IB1) between July 2017 and May 2019 were assessed for eligibility.
Interventions: RRH.
Measurements and Main Results: Subjective bladder function was evaluated with the Female Lower Urinary Tract Symptoms and Urinary Incontinence Quality of Life modules of the International Consultation on Incontinence Questionnaire. Objective urinary function was characterized with urodynamic tests, and the nerves ablated at RRH were quantified by using immunohistochemical staining of biopsies from the resected paracervix, vesicouterine, and sacrouterine ligaments. Twenty-seven women were included for analysis at baseline, 2 weeks, 3 months, and 12 months after surgery. RRH caused hypotonia of the urinary bladder (p <.05). Patient-reported outcomes of voiding and filling dysfunction were most significant 2 weeks after surgery (p <.05) but for most of the women, bladder function recovered within 3 months. No correlations were found with either subjective or objective urinary function and the number of ablated nerves.
Conclusion: For most women, objective and subjective urinary bladder dysfunction recovered within 3 months after RRH. The absence of correlation between functional outcomes and ablated autonomous nerves suggests that other underlying causes play a significant role. Early detection of bladder overextension after RRH is paramount, and the role of postoperative bladder catheterization needs further investigation.
