ABSTRACT
Objective To investigate the correlation between prostatitis and bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia.Methods From January 2008 to January 2012,Three hundred BPH patients were divided into two group according to whether had prostatitis determined by pathology.One hundred and thirty six patients with simple BPH and 164 patients with BPH combined with prostatitis were included with the median age of 69 years.PSA was (4.9 ± 8.3) μg/L and (7.0 ± 8.5)μg/L,the prostate volume was (41.4±18.1) ml and (48.7±20.7) ml,and IPSS was 21.9±7.0 and 27.5 ± 5.1 in BPH group and prostatitis group,respectively.The urodynamic parameters of bladder outlet obstruction between the two groups were analyzed.Results Qmax was (8.8 ± 4.8) ml/s and (6.3 ± 3.7)ml/s,Pdet.Qmax was (96.7 ± 33.0) cm H2O and (113.3 ± 39.8) cm H2O,AG value was 77.7 ± 31.9 and 93.9 ± 39.6,and Schafer grading value was 3.3 ± 1.5 and 4.4 ± 1.2 in BPH group and BPH combined with prostatitis group,respectively (P ＜ 0.05).Logistic regression analysis showed that prostatitis (OR =2.66,P =0.002),PV (OR =1.37,P =0.000),and Qmax(OR =0.72,P =0.000) were positively correlated with Schafer grading value.Conclusions Prostatitis increased the degree of BOO in patients with BPH.
ABSTRACT
Objective To investigate the clinical feature,pathologic characteristics and prognosis of non-muscle invasive urothelial bladder tumor in young and old patients.Methods From January 2000 to March 2011,the clinicial data of 48 young patients (age ≤ 40 years) with non-muscle invasive urothelial bladder tumor and 50 patients randomly selected with non-muscle invasive urothelial tumor (age ≥ 60 years) were analyzed and compared retrospectively.There were 38 male and 10 female with a median age of 35.4 years (range,18 to 40).There were 34 male and 16 female with a median age of 68.5 years (range,68.5 to 87).All patients had postoperative intravesical instillation for one year.Young patients presented with gross hematuria mostly,which were similmar with old patients.Solitary tumor were 45 cases and 40 cases,and the multiple tumors were 3 cases and 10 cases in the young and old groups,respectively.Of the young group,40 patients were treated by transurethral resection of bladder tumor,and 8 patients by partial cystectomy.Of the old group,35 patients were treated by transurethral resection of bladder tumor,and 15 patients by partial cystectomy.Results According to 2004 WHO classification of papillary urothelial tumor,lower grade tumor were more frequentto occur in young group than in old group.There was significant difference in incidence of PUNLMP between young group and old group (16/48,33.3％ and 8/50,16.0％,P ＜ 0.05).There was significant difference in incidence of high grade bladder cancer between young group and old group (7/48,14.6％ and 17/50,34.0％,P ＜0.05).The incidence of PTa tumor was 70.8％ and 44.0％ in the young and old groups,respectively (P ＜ 0.05).Median follow up was 34 months (range,6 to 132) in young group and 35 months (range,6 to 130) in old group,respectively.Five-year recurrence rate was 36.7％ and 64.3％ respectively (P ＜ 0.05).Conclusions Non-muscle invasive urothelial bladder tumor in young patients had a better prognosis than those in the old group,with lower grade and stage at diagnosisand lower recurrence rate.
