Objective: The aim of this study was to investigate the relationship between obstructive sleep apnea syndrome (OSAS) and lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH).Methods: This multicenter study was performed on 122 male patients with dyspnea and/or sleep disorder. Patient characteristics were recorded. All patients underwent full-night polysomnography, and the apnea-hypopnea index (AHI) was calculated. LUTS were evaluated using the International Prostate Symptom Score (IPSS) and prostate volume was calculated by transabdominal ultrasonography. Based on the AHI, patients were classified as normal or as having mild, moderate, or severe OSAS. Regression analyses were performed to identify independent predictive factors associated with nocturia.Results: Severe, moderate, and mild OSAS was present in 53, nine, and 46 patients, respectively, where 14 patients with dyspnea and sleep disorder were classified as normal. There were no significant differences between the severe and mild OSAS groups with regard to age, body mass index, systolic and diastolic blood pressure, smoking history, fluid intake, and serum creatinine and glucose concentrations. However, there was a significant difference between two groups in AHI (P < 0.001), nocturia (P < 0.001), and nocturnal voided volume (P = 0.011). Univariate and multivariate analyses revealed that age, smoking history, and an AHI >15 were independent predictors of nocturia.Conclusions: Sleep disorders are thought to be one reason for nocturia and nocturnal polyuria.Thus, OSAS must be considered in BPH patients who predominantly have storage symptoms.

PurposeThe aim of this study was to evaluate the relationship of seminal parameters with the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR), which are inflammatory markers, in men with an abnormal semen analysis and men with normozoospermia.Materials and MethodsFifty-seven men with abnormal semen analyses and 59 men with normozoospermia were included in this cross-sectional study. A complete blood count was recorded, and the NLR and PLR were calculated from the hematologic parameters.ResultsThe NLR was 1.84±0.78 in the normozoospermic group and 1.80±0.75 in the abnormal semen analysis group. The PLR was 95.32±35.47 in the normozoospermic group and 93.57±28.09 in the abnormal semen analysis group. No significant differences were found between the normozoospermic and the abnormal semen analysis group in the NLR (p=0.828) or the PLR (p=0.768). In addition, no seminal parameters were correlated with the NLR or the PLR (p>0.05).ConclusionsWe do not recommend using the NLR or the PLR as markers to screen for abnormal semen parameters or male infertility.

Materials and methods Study designAfter approval by our institutional review board, the medical records of 428 consecutive initially diagnosed Background/aim: Although it has been shown that the neutrophil-to-lymphocyte ratio (NLR) may predict the progression of nonmuscle invasive bladder cancer (NMIBC), its association with the recurrence of NMIBC has been poorly studied. The aim of this study is to evaluate the association between NLR and disease recurrence in patients with NMIBC. Materials and methods:The medical records of 428 consecutive initially diagnosed NMIBC patients who underwent transurethral resection between January 2010 and July 2014 were retrospectively reviewed. Patients without a preoperative NLR (n = 6), without a minimum of 6 months of follow-up (n = 56), who were lost to follow-up (n = 38), or who had progressive disease during follow-up (n = 42) were excluded. The demographics, tumor characteristics, and NLRs of patients with and without tumor recurrence were compared.Results: Of 286 patients who met the inclusion criteria, 68 (17.43%) had recurrent disease. Tumor size (P = 0.198), tumor type (P = 0.929), and the presence of carcinoma in situ (P = 0.373) were also similar between groups. Patients with recurrent disease had a higher mean NLR (2.62 ± 0.99 vs. 2.2 ± 0.96, P = 0.002). Conclusion:Our results show that NLR may be used as a predictor of recurrence in patients with NMIBC; however, prospective studies are required to validate these findings.
