良性前列腺增生手术前后尿动力学检查及其临床价值

Perioperative Urodynamic Studies on BPH Patients and Its Clinical Significance

目的探讨尿动力学检查在良性前列腺增生症(BPH)诊治中的价值。方法回顾性分析72例良性前列腺增生症患者手术前后尿动力学检查结果。结果 72例均有膀胱出口梗阻(BOO),其中40例伴有不稳定膀胱(DI),占55%。66例膀胱逼尿肌收缩正常或增强,6例膀胱逼尿肌收缩减弱。65例尿流率(UFR)低平,7例正常。手术后3个月,66例症状消失,2例出现并发症经再次处理治愈,不稳定膀胱15例,占21%,包括5例低顺应性膀胱。结论通过对良性前列腺增生症患者术前术后详细的尿动力学检查,可明确患者有无下尿路梗阻、膀胱逼尿肌顺应性和收缩功能及尿道括约肌功能。这对于合理选择病人及术后疗效判定有重要的指导意义。

Objective To investigate the clinical significance of urodynamic studies on BPH patients.Methods The perioperative urodynamic data of 72 BPH patients were retrospectively analyzed.Results All the patients were diagnosed with BOO preoperatively.Urodynamic studies showed that 40 patients(55%) had detrusor instability (DI).Detrusor contractility was normal or increased in 66 patients,decreased in 6 patients.Uroflowmetry rate(UFR) was normal in 7 and low in 65 cases.66 patients recovered in three months after prostatectomy, Two patients has complications after operation and they were treated with transurethral procedure again.15 patients (21%) had DI in which 5 cases had hypo-compliance bladder.Conclusions The urodynamic study could determine the presence and degree of BOO,the vesical compliance,the detrusor contractility and the urethral sphincter function.It would play an important role in selected patietns for operation.
