Objective To explore the effective method of the prevention and cure of unstable bladder after transurethral resection of prostate(TURP).Methods Ninety patients with benign prostatic hyperplasia(BPH)undergoing TURP under epidural anesthesia were randomly divided into 3 groups(with 30 patients in each group):treatment group,control group I and control group II.Tolterodine combined with diciofenac sodium/lidecaine hydrechloride injection were used after operation in treatment group.Control group I was only given tolterodine,and control group II was only given diclofenac sodium/lidocaine hydrochloride injection.Observed the incidence times and continuous time of unstable bladder after operation in three groups.Results Three cases(10.0%)happened to unstable bladder in treatment group and they were I degree,14 cases(46.7%)happened to unstable bladder in control group I,8 cases were I degree,5 cases were II degree,1 case was III degree;16 cases(53.3%)happened to unstable bladder in control group II,8 cases were I degree,6 cases were II degree,1 case was III degree,1 case was IV degree.There was obvious significance either between treatment group and control group I(P = 0.003)or between treatment group and control group II(P = 0.001).Conclusion Tolterodine combined with diclofenac sodium/ lidocaine hydrochloride injection have obvious effect on preventing the incidence of unstable bladder after TURP,it is easy to perform and can be used widely.

Objective To explore the effect of the prevention and treatment of unstable bladder after suprapubic prostaectomy by capsaicin instilled into the bladder preoperatively combined with patient-controlled epidural analgesia(PCEA)for benign prostatic hyperplasia(BPH).Methods Sixty patients with BPH underwent suprapubic prostatectomy under epidural anesthesia were randomly divided into control group (30 cases)and treatment group(30 cases),100 ml of 100 μmol/L capsaicin was instilled into the bladder preoperatively for 30 minutes combined with PCEA after operation in treatment group,the control group was only given PCEA.Observed the incidence and continuous time of unstable bladder after operation in two groups.Results Unstable bladder was found in 3 cases of treatment group and they were Ⅰdegree,12 cases happened unstable bladder in control group,3 cases Ⅰdegree,5 cases Ⅱdegree,3 cases Ⅲ degree,1 case Ⅳ degree.There was obvious significance between two groups (P＜0.05).Conclusion Capsaicin instilled into the bladder combined with PCEA can cut off the reflex arc of detrusor contraction more completely and has obvious effect of decrease the incidence of unstable bladder after suprapubic prostatectomy and can be used widely.
