Abstract:
Objective To observe the incidence and transformation of pyuria and bacteriuria in different time point after TURP and supply the evidence for antibiotic application.Methods From March,2011 to May,2012,84 patients with BPH admitted in our hospital.Their ages ranged from 61 to 87 years old,mean (71.9±7.6) years.The volume of prostate in those patients ranged from 27.8 to 118 ml,mean (70.8±24.1) ml.The procedure of TURP was undergone in all of them.In one week after the operation,two urine specimens from each patient,one for urine routine examination and one for urine culture,were collected 24 h after the catheter have been withdrawn.The catheter was also cultured.During the following-up,urine routine examination and urine culture were regularly performed in 1,2,3 months after surgery.If the patient had both pyuria and bacteriuria,he should be excluded the study.Results The pyuria rate on one week,one month,two months and three months were 54.8% (46/84),100.0% (82/82),65.8% (48/ 73),34.2% (25/73),respectively.There is a significance difference among those groups (P<0.05).It seemed that the pyuria would appear in all patients.However,the incidence would gradually decrease.It seemed that the pyuria has the tendency of self-recovery.A significant difference of prostatic resection volume after 3 months could be observed in the pyuria group (31.4±15.2 ml) and non-pyuria group (24.8±11.6 ml) (P<0.05).The bacteriuria rate on one week,1,2,3 months were 7.1% (6/84),11.0% (9/82),6.8% (5/73)and 0,respectively.There is no significance difference among the groups (P>0.05).Conclusions Pyuria will appear after TURP and the incidence reduced gradually following the time.The pyuria alone without the bacteriuria may be explained by inflammation,that antibiotics were unnecessary.The bacteriuria alone without the pyuria may be considered as asymptomatic bacteriuria or bacterial colonization,antibiotics were unnecessary,either.
