Purpose: The main objective of this study was to reveal the relationship between lower urinary tract symptoms (LUTS) and post-void residual (PVR) urine volume. Materials and Methods: Between October 2014 and February 2015, older than 40 years patients were included in this study. Volunteers filled out a questionnaire consisted of demographic characteristics, comorbidities, medications, history of surgery and LUTS. Volunteers were undergone PVR measurement with transabdominal ultrasonography. The relationship between symptoms, demographic characteristics and PVR were analyzed. Results: A total of 939 patients (756 men and 183 women) were enrolled in this study. There was a positive correlation between the sensation of incomplete bladder emptying and PVR volume in all age groups of women (p=0.0001). However such a relationship was found only over the age of 60 in the subgroup analysis of men (p=0.001). PVR volume increased in men by age (0.65 mL per year of age, p=0.011). In men, voiding symptoms and urgency were associated with a high PVR volume. In women, storage and voiding symptoms (except slow stream and terminal dribble) did not correlate with PVR volume. Conclusions: Our study showed that all men over the age of 60 years and all women with the complaint of feeling of incomplete emptying should undergone PVR measurement. Women with the complaint of poor stream and men mainly with voiding symptoms are other candidates in whom PVR measurement would be considered as an important tool in the clinical management and follow-up.

The renoprotective effects of mannitol and udenafil in renal ischemia-reperfusion injury model

Purpose: The aim of this study was to investigate and compare the effects of udenafil and mannitol in an experimental renal ischemia-reperfusion (I/R) injury model. Materials and Methods: A total of 64 female Wister Albino rats were used. Right nephrectomy was performed in all groups. In the control group; I/R injury was not performed. In the I/R group; left renal pedicle was clamped for 45 minutes and then underwent 60 minutes and 24 hours of reperfusion. In the mannitol group; 1 mL 20% mannitol was given intravenously 15 minutes before clamping. In the udenafil group; 10-mg/kg udenafil was given orally 1 hour before clamping. Creatinine (Cr), blood urea nitrogen (BUN), Cr clearance, malondialdehyde, neutrophil gelatinase associated lipocalin (NGAL), histological examination and DNA damage (Comet Assay method) levels were compared in tissue, serum and urine samples. Results: Udenafil had a better protective effect than mannitol according to biochemical parameters (Cr, BUN, Cr clearance, and NGAL levels) and histopathological findings when compared with the I/R group. In the Comet sampling analysis no significant difference was detected. Conclusions: Udenafil has a better renoprotective effect than mannitol against I/R injury and this effect supports more functional improvements. Further clinical trials are needed to demonstrate those effects and clinical utility of udenafil for that purpose in humans.

Purpose: The aims of this study were to assess the prevalence of nocturia and nocturnal polyuria (NP) and to define new cutoff values according to age and sex for both conditions. Methods: Data from a population-based prevalence survey conducted among a random sample of 2,128 adults were analyzed in this study. Participants were requested to fill out a questionnaire including the International Continence Society (ICS) definitions of lower urinary tract symptoms and the International Consultation on Incontinence Questionnaire - Short Form. Additionally, a 1-day bladder diary was given to each individual. The participants were divided into 5 age groups. The prevalence of nocturia was calculated based on definitions of nocturia as ≥1 voiding episodes, ≥2 episodes, and ≥3 episodes. NP was evaluated according to the ICS definition. The mean±standard errors and 95th percentile values were calculated in each group as new cutoff values for NP. Results: The prevalence of nocturia was estimated as 28.4%, 17.6%, and 8.9% for ≥1, ≥2, and ≥3 voiding episodes each night, respectively. When nocturia was defined as 2 or more voiding episodes at night, the prevalence decreased significantly. The mean NP index was 29.4%±15.0% in men and 23.1%±11.8% in women. For the age groups of <50 years, 50–59 years, and ≥60 years, the new cutoff values for the diagnosis of NP were calculated as 48%, 69%, and 59% for men and 41%, 50%, and 42% for women, respectively. Conclusions: We found that the definition of nocturia was still controversial and that waking up once for voiding might be within the normal spectrum of behavior. The definition of NP should be modified, and new cutoff values should be defined using the data presented in our study and in other forthcoming studies.
