AbstractWe compared the intensity of staining of interstitial cells (ICs) and neural tissue in the lower urinary tract of rabbits with diabetes with the intensity in normal subjects. Diabetes was induced by injecting alloxane (65mg/kg) in adult male rabbits. After 3 days, rabbits with a blood glucose level >300 mg/dL were considered to have diabetes. After 8 weeks, the rabbits were killed, and tissue specimens from the bladder, prostate and urethra were obtained. ICs were stained with anti-human CD117 (c-kit) rabbit polyclonal antibody, and neural tissue was stained with synaptophysin. The streptavidin-biotin method was used for immunohistochemical staining. The intensity of c-kit and synaptophysin staining were scored as negative (0), weak (+), moderate (++), and strong (+++). Staining intensity of ICs and neural tissue was assessed and compared in tissues obtained from rabbits with diabetes (n=8) and from control subjects (n=7). Although staining intensity of both ICs and neural tissue was found to be significantly decreased in the bladder tissue of rabbits with diabetes compared to that in the control group (p=0.0001 [ICs] and p=0.021 [neural tissue]), no significant differences in staining intensity of ICs and neural tissue in the urethra and in the prostate was found when rabbits with diabetes were compared to the control group. Diabetes may cause dysfunction of the lower urinary tract, particularly in the urinary bladder, as shown by the staining intensity of ICs and neural tissue.

Material and methods. The study included patients (n=164) in peri- and postmenopause, having a laboratory-confirmed picture of the genitourinary menopausal syndrome - atrophic vulvovaginitis and suffering from recurrent lower urinary tract infections (UTI) - cystitis and urethritis. All patients underwent standard antibacterial therapy (ABT) UTI in accordance with the results of bacteriological urine culture according to Russian clinical guidelines on urology. Against the background of ABT, 164 patients received additional therapy with Trioginal® (the study group - SG) containing estriol, micronized progesterone and Lactobacillus casei rhamnosus Doderleini 35 (LCR 35) lactobacillus strain. Trioginal® was administered intravaginally in two stages: for 20 days, 2 capsules per day, then for 10 days, 1 capsule per day. In the comparison group - CG (n=67) with ABT, Ovipol Klio® (estriol monopreparation) was additionally intravaginally used in two stages: for 14 days, 1 suppository per day, then for 2 weeks, 1 suppository 2 times a week. The control group consisted of 30 patients receiving only standard ABT UTI, local hormone therapy for vulvovaginal atrophy (VVA) was not performed. The observation period was 12 months after the end of the course of therapy. At all stages of treatment, a subjective and objective assessment of the severity of urination disorders and urogenital atrophy (UDI-6 questionnaire), their impact on the quality of life of patients (questionnaire IIQ-7), indicators of bacteriuria, bacterial urine culture and vaginal biocenosis, frequency of undesirable phenomena were carried out. According to the initial characteristics of the group of patients were comparable. Results. At all stages of the study, in the group of patients who received therapy with the use of the Trioginal® drug, there was a significant improvement in the clinical picture of urination disorders compared to the CG and the control (main) group - MG (in SG - 18% at the end of therapy versus 100% before the start of therapy; CG - 26 % versus 100% respectively; Ledger - 58% versus 100% respectively; p

To investigate the association among lower urinary tract infection (UTI), the type and timing of antibiotic usage, and the subsequent risk of developing cancers, especially genitourinary cancers (GUC), in Taiwan. This retrospective population-based cohort study was conducted using 2009–2013 data from the Longitudinal Health Insurance Database. This study enrolled patients who were diagnosed with a UTI between 2010 and 2012. A 1:2 propensity score-matched control population without UTI served as the control group. Multivariate analysis with a multiple Cox regression model was applied to analyze the data. A total of 38,084 patients with UTI were included in the study group, and 76,168 participants without UTI were included in the control group. The result showed a higher hazard ratio of any cancer in both sexes with UTI (for males, adjusted hazard ratio (aHR) = 1.32; 95% confidence interval (CI) = 1.12–1.54; for females, aHR = 1.21; 95% CI = 1.08–1.35). Patients with UTI had a higher probability of developing new GUC than those without UTI. Moreover, the genital organs, kidney, and urinary bladder of men were significantly more affected than those of women with prior UTI. Furthermore, antibiotic treatment for more than 7 days associated the incidence of bladder cancer in men (7–13 days, aHR = 1.23, 95% CI = 0.50–3.02; >14 days, aHR = 2.73, CI = 1.32–5.64). In conclusion, UTI is significantly related to GUC and may serve as an early sign of GUC, especially in the male genital organs, prostate, kidney, and urinary bladder. During UTI treatment, physicians should cautiously prescribe antibiotics to patients.

The aim of this work was to give an evidence of the likely presence of interstitial cells in the canine lower urinary tract and to study their possible interactions with the musculature and the intramural innervation. Cryosections of normal canine bladder and urethra were immunofluorescently labelled with c-kit, a transmembrane, tyrosine kinase growth factor receptor, known to be expressed on the interstitial cells of Cajal (ICCs) of the gut. The relationship with antiactin positive smooth muscle cells and PGP9.5-positive intramural innervation was also investigated by confocal microscopy. Anti-c-kit labelling demonstrated a network of elongated and branched c-kit positive cells, which were located in interstitial spaces, oriented in parallel to the smooth muscle bundles that form the bladder muscular layer, irrespective of dog sex. Cells with a similar localization were also PAS- and NADPH-diaphorase-positive. A contact between c-kit immunofluorescent cells and intramural innervation was demonstrated, too. The roles of interstitial cells might include regulation of smooth muscle activity of the bladder detrusor, integrating neuronal signals during urine storage and voiding.

Background: postcoital cystitis ranks first among recurrent infections of the lower urinary tract in young women. Their prevention is an important medical social issue. Prescription of antimicrobials for these infections increases antibacterial resistance of urinary tract pathogens, thereby requiring the search for alternative preventive strategies for postcoital cystitis. Aim: to assess the effectiveness of diet correction using biologically active food supplement (BAFS) Ecocystin® containing D-mannose and inulin to prevent coitus-related infections of the lower urinary tract (postcoital cystitis) in women. Patients and Methods: 40 sexually active women aged 18–45 (the mean age 31.9±8.8 years) with recurrent coitus-related infections of the lower urinary tract were enrolled. Women were divided into two groups, i.e., the study group (n=22) and the control group (n=18). Study group women received postcoital preventive treatment for the lower urinary tract infections (one sachet of BAFS Ecocystin® containing 1.5 g of mannose and 1.5 g of inulin no later than 2 hours after sexual intercourse and then another 12 hours later). Control group women received no preventive treatment. The primary indicator of the efficacy of postcoital prophylaxis was the rate of recurrent infections of the lower urinary tract. The additional indicator was the severity of clinical presentations assessed by the Acute Cystitis Symptom Score (ACSS) questionnaire. Follow-up was six months. Results: the rate of recurrent infections of the lower urinary tract was significantly lower in the study group compared to the control group. Recurrences were reported in 27.3% in the study group and 77.8% in the control group over months 1–3 (χ2=10.01, p=0.002) and 13.6% and 72.2%, respectively, over months 4–6 (χ2=14.16, p<0.001). The chances for cystitis exacerbation during the first and the second trimester of the follow-up were 2.9- and 5.3-times lower in the study group compared to the control group. During the first trimester of the follow-up, the recurrence rate was 0.45±0.86 per one woman of the study group and 1.55±1.10 per one of the control group (t=3.6, p<0.001). During the second trimester of the follow-up, the recurrence rate was 0.18±0.50 and 1.50±1.20 (t=4.7, p<0.001), respectively. Women who received BAFS Ecocystin® but developed postcoital cystitis reported much lower symptom severity than the control group. As a result, the study group’s quality of life was significantly higher than the control group’s. Conclusions: BAFS Ecocystin® is a highly effective and well-tolerated preventive tool for postcoital cystitis in women and a pathogenetically reasonable alternative for antibiotics.

Introduction: JJ stenting has been routinely used in endourology with a wide variety of implications. These stents have beneficial effects in postoperative period improving surgical outcome. Though they are widely used in urology practice, JJ stents cause lower urinary tract symptoms (LUTS) in majority of patients. The objective of this study was to test the hypothesis that alpha blockers reduce lower urinary tract symptoms (LUTS) after rigid ureterorenoscopy in postoperative time period up to 3 weeks. Study Design: It was a randomized clinical trial (RCT). Setting: The study was conducted in KRL hospital, Islamabad. Patients presenting in outpatient / emergency department were selected for the study. Duration of Study: Six months (15th July 2016 to 15th Jan’ 2017) Methods: A prospective randomized study was conducted in total 100 patients undergoing rigid ureterorenoscopy (URS). Patients were randomized into an intervention Group A and Control Group B. In Group A tamsulosin 0.4mg was given after rigid ureterorenoscopy, while in Group B no tamsulosin was given except placebo. Primary outcome were lower urinary tract symptoms (LUTS), which were measured by international prostate symptoms score (IPSS) up to 3 weeks postoperatively. Results: The mean IPSS at 3rd week in postoperative phase of rigid URS for Group A was 4.76± 4.14315 and in Group B was 27.28 ± 5.03879 with the P value of 0.0001 which was statistically significant and also less than 0.05. So IPSS was statistically lower in Group A as compared to Group B up to 3 weeks post operatively. In conclusion, a significant statistical difference was found for Double J (DJ) stent related symptoms between the two groups. Conclusion: Alpha blockers reduce lower urinary tract symptoms (LUTS) in postoperative period of rigid ureterorenoscopy up to 3 weeks.

Benign prostatic hyperplasia and its associated lower urinary tract symptoms seriously affect both the physical and mental health of older men. In order to determine the efficiency of Chinese Qigong Yi Jin Jing on prostate health in older individuals, thirty participants were randomized into either an Yi Jin Jing group (n = 15) or a control group (n = 15). After the 6-month intervention, the Yi Jin Jing group showed a significant decrease in international prostate symptom score and a significant increase in maximal urinary flow rate (compared with the control group p = .005, p = .001, respectively). Also, testosterone level increased and estrogen/testosterone ratio decreased in the Yi Jin Jing group (compared with the baseline p = .004, p = .002, respectively); estrogen level and estrogen/testosterone ratio were lower in the Yi Jin Jing group (compared with the control group p = .029, p = .012, respectively). The results showed that Yi Jin Jing is a promising way to reduce the risk of benign prostatic hyperplasia-lower urinary tract symptoms in older men.

Lower urinary tract dysfunction (LUTD) is a common problem in children and constitutes up to 40% of pediatric urology clinic visits. Improved diagnosis and interventions have been leading to better outcomes in many patients, whereas some children are left untreated or do not respond to the treatment successfully. In addition, many of these patients are lost by the pediatric urologists during their teenage years, and the outcome in later life largely remains unidentified. Studies suggest childhood LUTD is associated with subsequent adult urinary tract symptoms. However, whether and how early life LUTD attributes to urinary symptoms in those patients later in life remains to be elucidated. In the current study, we investigated the effects of early life voiding perturbation on bladder function using a neonatal maternal separation (NMS) protocol in mice. The NMS group displayed a delayed development of voluntary voiding behavior, a significant reduction of functional bladder capacity, and bladder overactivity compared with control mice later in life. In vitro evaluation of detrusor smooth muscle and molecular study showed a decrease in muscarinic contribution alongside an increase in purinergic contribution in detrusor contractility in NMS mice compared with control group. These results suggest that early life bladder dysfunction interfered with the normal maturation of the voluntary micturition control and facilitated LUTD in a later stage, which is at least partly attributed to an alteration of muscarinic and purinergic signaling in the urinary bladder.
