Evaluation of intrinsic sphincter deficiency (ISD) according to the urethral leak point pressure in female population with stress urinary incontinence.
Prospective clinical study.
Department of Urology, Jessenius School of Medicine Comenius University Martin, Slovak Republic.
Study population compromise of 204 females with lower urinary tract symptoms. Exclusion criteria were neurogenic bladder and unstable bladder. Valsalva leak point pressures were evaluated (VLPP). ISD was defined if VLPP below 65 cm H2O has been occurred. Pad weighing test (PWT) was positive after leakage of 2 g per hour and more.
Stress urinary incontinence was in 134 and continence in 70 cases (control group). The first stage of incontinence was in 83, the second stage in 45 and the third stage in 6 cases of incontinence group. ISD has been occurred in 14 cases (10.5%), 8 cases with the second stage and 6 cases with the third stage. The best correlation was between VLPP and PWT, symptoms of incontinence and age of patients. All ISD cases underwent antiincontinent surgery with urethral suspension, some years ago.
ISD has been risen in the second stage (6%) and the third stage (4.5%), also, in the female population with stress urinary incontinence.
根据尿道漏点压力评估女性压力性尿失禁患者的固有括约肌缺陷（ISD）。
前瞻性临床研究。
斯洛伐克共和国马丁市康梅纽斯大学耶塞纽斯医学院泌尿外科。
研究人群包括204名有下尿路症状的女性。排除标准为神经源性膀胱和不稳定膀胱。评估瓦尔萨尔瓦漏点压力（VLPP）。如果VLPP低于65 cm H₂O，则定义为ISD。每小时漏尿2克及以上时，护垫称重试验（PWT）为阳性。
134例为压力性尿失禁，70例为尿失禁（对照组）。尿失禁组中，83例为第一阶段尿失禁，45例为第二阶段，6例为第三阶段。14例（10.5%）发生ISD，其中8例为第二阶段，6例为第三阶段。VLPP与PWT、尿失禁症状和患者年龄之间的相关性最佳。所有ISD病例数年前均接受了尿道悬吊抗尿失禁手术。
在女性压力性尿失禁人群中，第二阶段（6%）和第三阶段（4.5%）也出现了ISD。
