摘要
目的 探讨女性原发性膀胱颈梗阻 (PBNO)的临床及尿动力学特点。 方法 回顾性分析 6 1例PBNO及 32例压力性尿失禁患者尿动力学检查资料。 结果 PBNO病人分为内括约肌痉挛症 (ISS)组及膀胱颈梗阻 (BNO)组 ,前者 41例 ,后者 2 0例。压力流率测定成功率ISS组低于BNO组及对照组 (4 9% ,80 % ,81% )。ISS组及BNO组Lin PURRBOO分级 >Ⅱ级者占 94% ,对照组 99%为 0～Ⅰ级。ISS组及BNO组与对照组比较差别有显著性意义的指标为膀胱颈开放逼尿肌压(PVB)、AG数 (PdetQmax- 2Qmax)、剩余尿量及最大尿道闭合压 (MUCP)。 结论 PBNO诊断的重要参数为Lin PURR分级、PVB及AG数 ,改良苄胺唑啉UPP试验是内括约肌功能性梗阻定性定位的良好指标 ,Lin PURR >
Objective To probe into the clinical and urodynamic features of primary bladder neck obstruction(PBNO) in females. Methods A retrospective analysis was made with comprehensive urodynamic evaluation in 61 cases with PBNO and 32 cases with genuine stress incontinence. Results According to the modified phentolamine UPP tests,there were 41 cases of internal sphincter spasticity(ISS)and 20 cases of bladder neck obstruction(BNO).The success rate of P Q plot analysis in the ISS group was lower than those of BNO and the control(49%vs 80% and 81%).94% of both ISS and BNO patients had a Lin PURR grading of ≥grade Ⅱ,whereas 99% of the control group were of grade 0 of I.There were a significant difference in such parameters as PVB,A G number(Pdet Qmax -2Qmax),post voiding residual,and maximum urethral closure pressure between the obstructed groups and nonobstructed group. Conclusions The meaningful diagnostic parameters for PBNO are Lin PURR grading(≥grade Ⅱ),PVB and A G number.The modified phentolamine UPP test is a reliable index for the assessment of internal sphincter sphincter functional obstruction.
