Abstract:
Objective To investigate the causes and the clinical significance of the female lower urinary tract symptoms (LUTS). Methods Of the 72 female patients (mean age,48 years;range,8 to 86 years) with LUTS,46 had dysuria,14 with incontinence,10 with frequency and urgency of micturition and 2 with nocturnal enuresis.Urodynamic examinations were conducted in these patients. Results Among the 46 cases with difficulty of urination,whose bladder volumes were 60 to 800 ml,20 had the bladder detrusor contractility of 0,and 26,of 9 to 160 cm H 2O.Linearised passive urethral resistance relation (Linp-URR) figure showed at least grade Ⅲ obstruction in 19 cases.The urethral pressure profiles (UPPs) were 25 to 130 cm H 2O.Dyssynergia of detrusor-external sphincter occurred in 33 cases with voiding dysfunction.Ten cases with frequency of micturition had bladder volume of 97 to 450 ml.Two cases had the bladder detrusor contractility of 0,the other 8 cases were of 9 to 160 cm H 2O.Linp-URR figure showed at least grade Ⅲ obstruction in 2 cases.One case with urgent incontinence had hyper-sensitive bladder.The abdominal leak point pressures were 44 to 76 cm H 2O in 6 cases of stress incontinence.3 cases of overflowing urinary incontinence had no contraction of bladder detrusor and the UPPs were 32 to 42 cm H 2O.The UPPs were 0 to 16 cm H 2O in the 4 cases of total urinary incontinence.Two cases of nocturnal enuresis had detrusor instability with impaired contractility. Conclusions Urodynamic examination is necessary to the diagnosis of female LUTS and it also has significant value in predicting the treatment and prognosis of LUTS.
