The aim of this study was to demonstrate the impact of the nerve-sparing radical hysterectomy on the bladder function.
Patients with cervical cancer stage 1B1 to IIB, who underwent type 3 to 4 nerve-sparing radical hysterectomy, were evaluated with urodynamic test before and within 6 months from surgery. Stage IB2 to IIB patients were treated with platinum-based neoadjuvant chemotherapy. Bladder catheter was removed in postoperative day 4, and patients were educated to clean intermittent self-catheterization. Urinary symptoms were evaluated with a questionnaire administered before and 3, 6, and 12 months after surgery. Patients treated with adjuvant chemoradiotherapy were excluded from the study.
Fifteen patients (stage IB1, 7; IB2, 3; and IIB, 5) completed the study. Eight (53%) patients were treated with neoadjuvant chemotherapy. Bilateral nerve sparing was feasible in 13 (87%) patients, unilateral in 2 (13%). At postoperative day 10, only 3 (20%) patients continued intermittent self-catheterization. Before surgery, 1 (6.2%) patient had urodynamic symptoms of incontinence, and 3 (20%) had overactive bladder detrusor. Postoperative urodynamic study (median, 4 months; range, 3-6) showed reduced detrusor activity in 8 (53%), overactive detrusor in 4 (27%), and normal profile in 3 (20%) patients. Reduced bladder sensation was observed in 2 (12.5%), and residual urine more than 30% of bladder capacity in 2 (12.5%) patients, respectively. No patient showed de novo incontinence. Bladder compliance was unchanged.
The separation of the hypogastric nerve from the parametrium is a feasible surgical step, which can be implemented in the radical hysterectomy technique in different clinical settings. The comparative urodynamic study showed a mild functional impairment in the early postoperative period. The most frequent finding was the reduced detrusor activity observed during the voiding phase, consistent with the straining needed to void reported in the questionnaire. These data suggest that a mild bladder impairment occurs despite the conservation of the hypogastric nerve.
本研究旨在展示保留神经的根治性子宫切除术对膀胱功能的影响。
对接受 3 型至 4 型保留神经根治性子宫切除术的宫颈癌ⅠB1 期至ⅡB 期患者,在术前和术后 6 个月内进行尿动力学检查。ⅠB2 期至ⅡB 期患者接受含铂新辅助化疗。术后第 4 天拔除膀胱导管,对患者进行清洁间歇性自家导尿教育。在术前和术后 3、6 和 12 个月通过问卷调查评估尿症状。排除接受辅助放化疗的患者。
15 例患者(ⅠB1 期 7 例,ⅠB2 期 3 例,ⅡB 期 5 例)完成了研究。8 例(53%)患者接受了新辅助化疗。13 例(87%)患者行双侧神经保留,2 例(13%)行单侧神经保留。术后第 10 天,仅有 3 例(20%)患者继续间歇性自家导尿。术前,1 例(6.2%)患者有尿动力学表现为尿失禁,3 例(20%)患者有逼尿过度性膀胱。术后尿动力学检查(中位数为 4 个月;范围为 3-6 个月)显示 8 例(53%)患者逼尿肌活动减少,4 例(27%)患者逼尿肌过度活动,3 例(20%)患者逼尿肌正常。2 例(12.5%)患者膀胱感觉减退,2 例(12.5%)患者残余尿量超过膀胱容量的 30%。无一例患者出现新发尿失禁。膀胱顺应性无变化。
从宫旁组织分离腹下神经是一种可行的手术步骤,可在不同的临床环境下应用于根治性子宫切除术。比较性尿动力学研究显示,术后早期膀胱功能轻度受损。最常见的发现是在排尿期观察到逼尿肌活动减少,与问卷中报告的排尿时需要用力相吻合。这些数据表明,尽管保留了腹下神经,但仍会出现轻度的膀胱损伤。
