目的:提高经尿道腔内手术治疗膀胱颈部梗阻的诊治水平。方法:对33例保守治疗无效的膀胱颈部梗阻女性患者行经尿道膀胱颈部电切术。结果:28例患者(84.8%)术后排尿症状明显改善,在手术后6～12周梗阻症状消失。最大尿流率和剩余尿量明显改善,手术前后平均尿流率分别为(6±4)ml/s、(28±10)ml/s(P<0.05)。切除的膀胱颈部组织病理报告为纤维平滑肌组织增生伴或不伴慢性炎细胞浸润。随访6～58个月,平均18个月,5例在术后2～4年膀胱颈部梗阻症状复发,3例行再次电切后症状改善,2例再次电切,随访3个月无效后行膀胱造瘘术。均未发生尿失禁和尿瘘等并发症。结论:经尿道电切术治疗女性膀胱颈部梗阻手术操作简单、创伤小、出血少,疗效肯定。 Objective: To improve the diagnosis and treatment of bladder neck obstruction by transurethral surgery. Methods: Twenty-three female patients with bladder neck obstruction who were ineffective in conservative treatment underwent transurethral resection of bladder neck. Results: 28 cases (84.8%) had obvious improvement of urination symptoms and obstructive symptoms disappeared 6 to 12 weeks after operation. The maximum urinary flow rate and residual urine volume were significantly improved. The mean urinary flow rates before and after surgery were (6 ± 4) ml / s and (28 ± 10) ml / s, respectively (P <0.05). Excised bladder neck histopathology was reported as fibrofacial tissue hyperplasia with or without chronic inflammatory cell infiltration. All patients were followed up for 6 to 58 months with an average of 18 months. Five patients had recurrent bladder neck obstruction 2 to 4 years after operation. The symptoms were improved in 3 patients after resection, and in 2 patients, the resection was performed again. After 3 months of follow-up, Bladder ostomy. Neither incontinence nor urinary fistula occurred. Conclusion: Transurethral resection of bladder neck obstruction in female patients with simple operation, less trauma, less bleeding, and sure effect.
