ABSTRACT

Objective:To investigate the efficacy of Mirabegron plus microecologics for the treatment of overactive bladder(OAB)in elderly women.Methods:In this prospective study, 104 patients diagnosed with OAB in the urology department of our hospital between February 2020 and December 2021 were recruited.The participants were randomly divided into two groups, with 52 in each.Group I was treated with Mirabegron alone(50 mg, qd)and Group Ⅱ was treated with Mirabegron(50 mg, qd)plus probiotics(3.5 g, bid)for 12 weeks.The efficacy was evaluated based on results before and after treatment, using measurements including the daily frequencies of urinary urgency, nocturia, daytime urination, urge incontinence and bladder capacity.The overactive bladder symptom score(OABSS), the quality-of-life score, and the number of lower urinary tract infections during treatment were also collected.Results at different treatment stages(week 4 and week 12)were compared within each group and between the two groups by Dunnett's test.Results:The symptoms of OAB in both groups were significantly improved after 12 weeks' treatment.In the group(Group Ⅱ)receiving the combination of two drugs, results from four measurements, the frequency of 24-hour urination(6.6 ± 0.7 vs.7.1 ± 1.2), the frequency of 24-hour urinary urgency(0.6 ± 0.6 vs.1.1 ± 0.7), the frequency of daily nocturia(0.8 ± 0.7 vs.1.3 ± 0.6)and the quality-of-life score(1.2 ± 0.7 vs.2.3 ± 0.8), were all significantly more favorable than in the group(Group I)treated with Mirabegron( P<0.05).The incidence of lower urinary tract infections and constipation was significantly reduced in the group with drug combination treatment. Conclusions:The efficacy of Mirabegron combined with microecologics for the treatment of OAB is better than that of Mirabegron alone, and the incidence of adverse events such as infections and constipation is also lower.

ABSTRACT

To evaluate the anti-cicatricial and anti-restenosis effect of verapamil on anterior urethral stricture.
 Methods: A total of 32 patients received anterior urethral stricture were enrolled in this study. They were divided into 4 blocks according to the duration of previous urethral operations and dilations. Every block was further randomly divided into an experimental group and a control group. Experimental groups received 2 mL injection of verapamil around the anastomosis site of urethra before and after the surgery (2, 4, 6, 8, and 10 weeks after the surgery), while the control groups only received the anastomosis surgery. After surgery, maximal urinary flow rate (Qmax) was examined for all patients once the catheter was removed. In addition, they were also conducted palpation of urethral scar range. The sum of long transverse diameters of urethral scar was measured, and the narrowest urethral inner diameter was examined. The Qmax was rechecked and the urethral scar range was assessed by penis color Doppler elastography after 12 weeks of surgery. The above 4 indexes were used to evaluate the inhibitory effect of verapamil on urethral scar.
 Results: The length of palpated urethral scar in the Block 1 to 4 of the experimental groups was (22.75±1.03), (21.25±0.25), (20.75±1.03), and (20.0±0.58) mm, respectively; and those in the control groups (26.00±0.82), (24.5±1.04), (25.75±1.65), and (28.25±1.75) mm, respectively. The Qmax rates in the Block 1 to 4 of the experimental groups were (11.85±0.77), (11.33±0.81), (10.23±0.26), and (10.35±0.17) mL/s, respectively; and those in the control groups were (10.85±0.39), (10.50±0.76), (10.53±1.00), (12.60±0.39) mL/s, respectively. The Qmax rates in the Block 1 to 4 of the experimental groups were (11.73±0.87), (10.65±0.25), (10.23±0.19), and (10.35±0.29) mL/s, respectively; and those in the control groups were (8.05±0.28), (7.73±0.68), (7.53±0.92), and (9.60±0.32) mL/s, respectively. The narrowest diameters of urethral in the Block 1 to 4 of the experimental groups were (9.00±0.58), (7.50±2.89), (7.00±0.10), and (7.00±0.41) mm, respectively; and those in the control groups were (5.50±0.29), (5.00±0.41), (4.75±0.48), and (6.75±0.48) mm, respectively. The ultrasound strain ratio in the Block 1 to 4 of the experimental groups were 6.10±0.22, 6.10±0.17, 5.10±0.16, and 6.90±0.19, respectively; and those in the control groups were 8.00±0.25, 10.60±0.29, 11.30±0.16, and 8.90±0.33, respectively. Compared with the control groups, the experimental groups displayed smaller urethral scar range, less severe scarring, improved Qmax rates and wider inner diameters (all P<0.05).
 Conclusion: Urethral regional injection of verapamil intraoperatively or postoperatively can prevent overgrowth of urethral scar tissues after the transperineal anastomosis surgery, and reduce the tendency of postoperative restenosis of anterior urethral stricture.

ABSTRACT

Objective To discuss the clinical effects of transurethral seminal vesiculoscopy in refractory hemospermia caused by seminal vesicle diseases.Methods The clinical data of 50 patients suffered from refractory hemospermia caused by seminal vesicle gland diseases were retrospectively analyzed from February 2012 to February 2014.Patients' age varied from 25 to 54 years old,mean (39.2 ± 9.2) years.The course of disease was (7.44 ± 2.6) months.There were 24 seminal vesiculitis,10 seminal ducts obstruction disease,and 16 seminal vesicle calculi disease.According to patients' priority,the patients were divided into surgical treatment group and conservative treatment group.In surgical group,there were 38 patients with age of (38.9 ± 8.8) years old,and the course of disease was (7.5 ± 2.5) months.There were 18 seminal vesiculitis,8 seminal ducts obstruction,and 12 seminal vesicle calculi.Whereas in conservative treatment group,there were 12 patients,with age of (40.2 ± 10.5) years old,and the course of disease was (7.3 ±2.9) months.Among them,there were 6 seminal vesiculitis,2 seminal ducts obstruction,and 4 seminal vesicle calculi.There was no significant difference between the two groups in patients age,course of disease and constitution of disease.The clinical data derived from the two treatment groups including the white blood cell counts (WBC) and red blood cell counts (RBC) in the seminal fluid,hematospermia rate,quality of life score,cure rate and improvement rate before and after the treatment were analysed.Results 1,3,6 months and 1 year after treatment,all observation indexes in the two groups had been ameliorated and had significant difference compared with those before treatment including WBC and RBC in the seminal fluid,hematospermia rate and quality of life score.No operative complications occurred in conservative treatment group.While a patient in surgical treatment group suffered from infection and recovered after levofloxacin treatment for a day.Six months after two kinds of treatment,in surgical treatment group,the cure rate was 55.2%,and the improvement rate was 36.8%.In the meanwhile,in conservative treatment group,the cure rate and the improvement rate were both 25.0%.A year after two different treatment,in surgical treatment group,the cure rate was 60.5%,the improvement rate was 34.2%.However,in conservative treatment group,the cure rate and improvement rate were both 8.3%.The effective rate of surgical group was much higher than that of conservative treatment group and the difference were significant.Conclusions Both transurethral seminal vesiculoscopy and conservative treatment have certain effects in relieving hemospermia.The transurethral seminal vesiculoscopy has obvious advantages over conservative treatment in improving the clinical effects of hemospermia after long duration.It could be used as a good supplement when medication fail.

ABSTRACT

To investigate effects of verapamil on primary cultured human urethral scar fibroblasts (USFs) and to provide basis for protecting the formation of urethra scar.
 Methods: The cell proliferation was evaluated with the cell counting kit (CCK)-8 method after USFs were incubated various verapamil concentrations (50, 100, 150, 200, or 250 μmol/L) or solvent for 12, 24, or 48 h. The protein level of matrix metalloproteinase (MMP) was evaluated with ELISA after cells were incubated with verapamil (100 μmol/L) or solvent (control cells) for 24 h.
 Results: The proliferation of USFs was obviously suppressed after verapamil treatment, which was in a dose-dependent and time-dependent manner. Meanwhile, the protein levels of MMP-2 and MMP-9 in the verapamil treatment group increased obviously compared with those of the control groups (P<0.05).
 Conclusion: Calcium channel blockers may prevent the excessive formation of urethra scar by inhibiting the proliferation of urethral scar fibroblasts and enhancing the activity of MMP.

ABSTRACT

OBJECTIVE@#To explore the mechanisms for urinary system disorders before and after ketamine withdrawal in rats and to evaluate the recovery degree of the urinary system damage after ketamine withdrawal.@*METHODS@#Fifteen male healthy Sprague-Dawley rats were randomly divided into 3 groups: A control group, an experimental group, and a withdrawal group. The rats in the control group were given normal saline. The rats in the experimental group were given ketamine 30 mg/(kg.day) for 30 days. The rats in the withdrawal group were treated as the experimental group except for drug withdrawal for 2 weeks. In the experimental period, we randomly selected 1 rat of kidney, ureter, and bladder from each group to perform HE staining. The bladder tissues in each group were used to detect mRNA expression by quantitative real-time polymerase chain reaction (qRT-PCR).@*RESULTS@#1) The behavior of ketamine-injected rats was obviously changed, but the weight of ketamine-induced rats was not changed. 2) As compared with the control group, the experimental and withdrawal groups showed infiltration of mononuclear inflammatory cells in the kidney tissues, the thinner epithelium of bladder and infiltration of submucosal mononuclear inflammatory cells under the optical microscope. 3) As compared with the control group, the expression of H1R mRNA was increased in the experimental group (P<0.05). As compared with the experimental group, H1R mRNA expression was significantly decreased in the withdrawal group (P<0.05).@*CONCLUSION@#Ketamine abuse could induce behavior changes in rats. The infiltration of mononuclear inflammatory cells in kidney and bladder, the thinner bladder epithelial layer, and the increased H1R gene mRNA expression in bladder might be an important pathogenesis of KAUD. Ketamine withdrawal may effectively reverse the pathogenic process of KAUD.

ABSTRACT

OBJECTIVE@#To establish logistic regression model for prostate cancer and provide basis for prostate biopsy.
@*METHODS@#A total of 117 cases of prostate biopsy were retrospectively analyzed in chronological sequence. All cases were assigned into a model group (n=78) and a validation group (n=39). Logistic regression model was established and its value was estimated by receiver operating characteristic (ROC) curve. 
@*RESULTS@#Digital rectal examination(DRE), transrectal ultrasound(TRUS), MRI, prostate-specific antigen density (PSAD), and free PSA/total PSA (fPSA/tPSA) were the influential factors for prostate biopsy (P<0.01). The established logistic regression model for prostate cancer by regression coefficient was: logit P=-2.362+2.561×DRE+1.747×TRUS+2.901×MRI+1.126×PSAD-
2.569×fPSA/tPSA and area under curve was 0.907. When the cutoff aimed at 0.12, the sensitivity and specificity were 81.80% and 89.30%, respectively.
@*CONCLUSION@#Logistic regression model for prostate cancer can provide sufficient basis for prostate biopsy. Prostate biopsy should be performed when P value is more than 0.12.
