Urodynamic analysis of benign prostatic hyperplasia (600 cases)

【Objective】 To study the urodynamic analysis of benign prostatic hyperplasia,to evaluate the value of urodynamics in the diagnosis and surgery of the patients with benign prostatic hyperplasia.【Methods】 Urodynamic tests and urodynamic evaluation of the treatment were made to 600 cases with benign prostatic phyperplasia so as to provide the theoretical basis for surgical treatment.【Results】 All the 600 cases suffered from bladder outlet obstruction(BOO),303 cases had pure BOO without bladder dysfunction(50.5%),102 cases suffered from bladder instability(15.45%),109 cases had low compliance bladder(18.16%),49 cases suffered from unstable bladder with low compliance(8.16%),83 cases had weak detrusor contraction(13.83%),and 3 cases had detrusor sphincter dysfunction(0.5%).【Conclusions】 Urodynamic test can evaluate the function of bladder and urethra and have very important value to dignoes BOO of BPH,appraise the function of detrusor muscle,select and predict the therapy.
