PurposeMetabolic syndrome and obesity have been advocated to be risk factors for the development of overactive bladder (OAB). Additionally, insulin resistance is the underlying mechanism of metabolic syndrome. We aimed to investigate the association of insulin resistance with overactive bladder in female patients.MethodsWe prospectively conducted the study in our urology department. Female patients aged between 30 and 76 years old applied to our policlinics with or without OAB symptoms were enrolled. One hundred and twenty-two patients with OAB and 62 age-matched controls without OAB were included into the study. Fasting serum insulin, glucose, high-density lipoprotein (HDL-c), and triglycerides levels were measured. Insulin resistance value was obtained via the homeostasis model assessment of insulin resistance (HOMA-IR) calculator. The chi-square and Mann-Whitney U tests were used to compare differences in variables.ResultsSerum insulin level was found higher in female patients with OAB (11.5±6.2 µU/mL) relative to controls (6.4±2.1 µU/mL), statistically significant (P=0.036). In addition, HOMA-IR was significantly found higher in the OAB group, 2.86 (0.76 to 17.04) in comparison to controls, 1.32 (0.67 to 224), P=0.018. High-density lipoprotein cholesterol levels (HDL-c) were significantly found lower in females with OAB.ConclusionsInsulin resistance can be associated to overactive bladder and may play significant role in pathogenesis.
Vascular impairment was found to be associated with LUTS in both men and women. Atherosclerosis-related vascular risk factors are also known to be related to LUTS and both disorders may have pathogenic interactions.
NAFLD is associated with BPH in men and with OAB in women. These findings confirm the hypothesis that BPH is an aspect of the metabolic syndrome and support the hypothesis that OAB is an aspect of the metabolic syndrome.
PurposeBladder wall thickness has been reported to be associated with overactive bladder (OAB) in women. Diabetic women have an increased risk for OAB syndrome and may have an increased risk for bladder wall thickness.MethodsA total of 235 female patients aged 40 to 75 years were categorized into four groups. The first group consisted of women free of urgency or urge urinary incontinence. The second group included nondiabetic women with idiopathic OAB. The third group consisted of women with diabetes and clinical OAB, and women with diabetes but without OAB constituted the fourth group. Bladder wall thickness at the anterior wall was measured by ultrasound by the suprapubic approach with bladder filling over 250 mL.ResultsThe diabetic (third group) and nondiabetic (second group) women with OAB had significantly greater bladder wall thickness at the anterior bladder wall than did the controls. However, the difference was not significant between the diabetic (third group) and the nondiabetic (second group) women with OAB. Women with diabetes but without OAB (fourth group) had greater bladder wall thickness than did the controls but this difference was not significant. Additionally, the difference in bladder wall thickness between diabetic women with (third group) and without (fourth group) OAB was not significant.ConclusionsThis is the first study to show that bladder wall thickness is increased in diabetic women with and without OAB. Additionally, nondiabetic women with OAB had increased bladder wall thickness. Further studies may provide additional information for diabetic and nondiabetic women with OAB, in whom the etiopathogenesis of the disease may be similar.
BackgroundUrethral stricture is a common condition, and direct vision internal urethrotomy is prefered as the first treatment option by many urologists, for strictures shorter than 2 cm. This procedure is generally performed under general or spinal anaesthesia.ObjectivesTo investigate the feasibility of adding local urethral anaesthesia to intravenous sedation and analgesia (sedoanalgesia) methods in patients undergoing internal urethrotomy.Patients and MethodsA total of 21 and 15 patients with anterior urethral strictures underwent internal urethrotomy under local urethral anaesthesia, with or without sedoanalgesia, respectively. Patient discomfort and pain levels were evaluated using the visual analog scale (VAS). Statistical analyses were calculated with a Mann-Whitney U test to compare difference in VAS scores between the subjects in both groups.ResultsTwo of the 15 (13%) patients operated under local urethral anaesthesia without sedoanalgesia were converted to general anaesthesia due to patient intolerability. Mean pain VAS scores for patients operated under 2% lidocain urethral gel anaesthesia with or without sedoanalgesia were 2.86 cm and 4.5 cm, respectively (P = 0.001). In addition, a VAS score over 3 cm was found in 3 of the 21 (14%) patients with, and 13 of the 15 (86%) patients without sedoanalgesia (P = 0.001).ConclusionsThe addition of intravenous sedoanalgesia improved the VAS scores of pain and discomfort, compared to patients operated under only local urethral anaesthesia. This may offer patients safer anaesthesia and shorter operative times with equilavent results in selected patients.
Background Prostate‐specific antigen (PSA) synthesis is related to testosterone, which has a diurnal rhythm. PSA might have a diurnal variation and the timing of measurement could change the clinical practice for prostate biopsy. Methods Male patients complaining of lower urinary tract symptoms (group 1) and diagnosed with prostate cancer (group 2) were recruited into the study. Morning fasting blood samples were withdrawn between 9.00 and 11.00 am for the determination of biochemical parameters, PSA (PSA1), total testosterone (T1), and estradiol (E1) levels. In the afternoon, between 15.00 and 15.30 pm, blood samples were again obtained from the same participants at the same day and the serum concentration of PSA (PSA2), total testosterone (T2), and estradiol (E2) were measured. Results A total of 160 and 30 patients were enrolled in groups 1 and 2, respectively. One hundred forty (87.5%) and 26 (86.6%) patients had a decrease in the PSA levels when measured in the afternoon. The Wilcoxon signed‐rank test determined a statistically significant difference between the PSA levels measured in the morning and in the afternoon in each group. An analysis of covariance test revealed no statistically significant difference in PSA concentration between the groups after adjustment for baseline concentration (F(1.187) = 0.203, P = .653). There was a weak positive correlation between PSA1/PSA2 and T1/T2, rs (160) = 0.163, P = .034. An extra unit increase in PSA1 concentration leads to a 0.805 (95% confidence interval [CI], 0.781‐0.830) and 0.828 (95% CI, 0.807‐0.849) ng/mL increase in PSA2 concentration in groups 1 and 2, respectively, that is, patients with and without prostate cancer had a similar decrease in the PSA levels. When measured in the afternoon, 66.6% and 50% patients with a morning PSA level over 3 or 4 ng/mL had a PSA drop below these levels, respectively. Conclusions PSA has a diurnal variation and the timing of measurement may alter the decision of the clinician for transrectal ultrasound prostate biopsy.
