Male Urethral Stricture in Patients with Metabolic Syndrome

OBJECTIVE

Urethral stricture is characterized by fibrosis that decreases urine flow. Metabolic syndrome is a complex disorder that causes fibrosis in many organs. This study aimed to evaluate the relationship between metabolic syndrome and appearance of urethral stricture and effects of metabolic syndrome on the recurrence of urethral stricture in patients with primary urethral stricture who underwent direct visual internal urethrotomy.

MATERIALS AND METHODS

One hundred thirty-two male patients who underwent direct visual internal urethrotomy between 2014 and 2021 because of primary urethral stricture were included. Location, length, and type of urethral stricture, time from diagnosis to surgery, postoperative follow-up, time from surgery to recurrence, and postoperative follow-up duration with a urethral catheter were retrospectively analyzed and association with metabolic syndrome was evaluated.

RESULTS

The mean age was 50.48 ± 17.94 years. Recurrence was found in 34.1% and metabolic syndrome in 27.3%. Postoperative follow-up duration was significantly longer in patients with recurrence than in those without (P=.033). There was no statistically significant difference in terms of metabolic syndrome and postoperative urethral catheterization between patients with and without recurrence (P=.126, P=.714, respectively). Postoperative clean intermittent self-catheterization use was found to be statistically higher in patients with recurrence than in patients without recurrence (P=.018). Postoperative urinary tract infection rate was found to be significantly higher in patients with metabolic syndrome compared to patients without metabolic syndrome (P=.001).

CONCLUSION

Metabolic syndrome was not associated with recurrence. However, postoperative urinary tract infections were more common in patients with metabolic syndrome than in patients without. Clean intermittent self-catheterization used postoperatively may increase the risk of stricture.

Evaluation of factors associated with the detection of incidental prostate cancer after open prostatectomy for benign prostatic hyperplasia

We aimed to evaluate the incidental prostate cancer (PCa) rate and predictive factors in patients who underwent open prostatectomy (OP) with a pre-diagnosis of benign prostatic hyperplasia (BPH). This study included patients with a pre-diagnosis of BPH, who underwent OP due to symptomatic prostate enlargement. Our database included age, medications, prostate-specific antigen (PSA), free/total PSA ratio, PSA density, digital rectal examination (DRE), prostate volume, serum neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, aspartate aminotransferase/alanine aminotransferase ratio, presence of metabolic syndrome (MetS) and histopathological results after OP. Of the 430 patients that underwent OP, 406 (94.4%) with a benign pathological diagnosis were evaluated as the benign group and 24 (5.6%) detected to have PCa constituted the incidental PCa group. The rate of incidental PCa was much higher in the elderly patients. The cut-off value of age was 71.5 years in the PCa group according to the receiver operating characteristic curve analysis. According to the multivariate analysis, DRE and the presence of MetS were effective in predicting PCa (p < .001 and p = .031, respectively). DRE was found 16 times more effective and MetS was 2.8 times more effective than the other parameters. Our results showed that DRE and the presence of MetS could be useful predictive factors of incidental PCa in OP.

Examining cerebral metabolic abnormalities in chronic obstructive pulmonary disease (COPD) patients by localized proton magnetic resonance spectroscopy (MRS)

PURPOSE

The study was planned based on the hypothesis that cerebral metabolism is impaired in chronic obstructive pulmonary disease (COPD) by using localized in vivo proton magnetic resonance spectroscopy.

MATERIALS AND METHODS

The study comprised 30 male patients, aged 45-70 years, with moderate level COPD and an aged matched group of 30 healthy males as the control group. Cerebral metabolism was investigated with proton magnetic resonance spectroscopy (MRS) using multivoxel technique. Data normal distribution conformity was evaluated by the One Sample Kolmogorov Smirnov Test and homogeneity by the One-Way ANOVA test. For both the COPD and control group, data were obtained as mean, standard deviations, minimum and maximum values. Independent sample t-test was used for the comparison of means between the two groups.

RESULTS

The frontal and parietal white matter in patients with COPD showed an overall reduction in cerebral metabolites. The NAA (N-acetylaspartate)/Cr (Creatinine), Cho (Choline)/Cr ratios of the cerebral frontal and parietal white matter regions in the COPD group were significantly lower than the control group.

CONCLUSIONS

The findings of this study through the use of MRS confirmed that most patients with symptomatic COPD have cerebral metabolic abnormalities.
