Abstract:
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.
