Diagnostic value of voiding scores of the "International prostate symptom score" and the "Bristol female lower urinary system symptoms-short form" questionnaires in women with voiding dysfunction
(Wolters Kluwer Medknow Publications, 2024) Erbay,M.E.; Sevinç,B.H.; Tarhan,F.
Introduction: We aimed to investigate the diagnostic value of International Prostate Symptom Score voiding symptom score (IPSS VS) and Bristol Female Lower Urinary Tract Symptoms short form voiding score (BFLUTS VS) in female patients with urodynamically diagnosed voiding dysfunction. Methods: The medical records of female patients who underwent urodynamic examination between May 2007 and November 2021 for lower urinary tract complaints were retrospectively evaluated. A total of 1858 female patients were included in the study. Patients investigated between 2007 and 2014 were asked to fill the IPSS, and patients investigated after 2015 were asked to fill the BFLUTS SF. Results: The mean age of the patients was 49.06 ± 0.33 in the IPSS group and 50.02 ± 0.47 in the BFLUTS group. On the pressure flow study, voiding dysfunction was found in 14.8% (n = 95) in the IPSS group and 15.1% (n = 183) in the BFLUTS group. The area under curve value was found to be 0.58 for IPSS and 0.64 for BFLUTS. Threshold values were found as >9 for IPSS VS and >4 for BFLUTS VS. The sensitivity, specificity, false negative, and false positive rates for IPSS VS were 33.3%, 78.8%, 66.7%, and 21.2%, respectively. The same parameters were 45.5%, 78.9%, 54.5%, and 21.1% for BFLUTS VS, respectively. Conclusion: The diagnostic performance of both the questionnaires was found to be low for diagnosing voiding dysfunction in female patients according to our data. Therefore, the assessment of the voiding phase in women should not solely rely on the current questionnaires. However, further studies using questionnaires including all voiding symptoms are required. © 2024 Indian Journal of Urology.

Does ejaculation have an effect on urinary flow rates?
(John Wiley and Sons Inc, 2024) Erkan Erbay,M.; Tarhan,F.
Introduction: The primary objective of this investigation is to explore the impact of ejaculation on urinary flow rates in men experiencing lower urinary tract symptoms. Materials and Methods: This study involved the enrollment of 55 male patients who presented with lower urinary tract symptoms. An assessment encompassed components, including medical history, questionnaires related to sexual activity and lower urinary tract symptoms, bladder diary, physical examination, urinalysis, urine culture, ultrasound examination and measurements of serum prostate-specific antigen, free flow uroflowmetry, and post-void residual urine volume. All participants were instructed to abstain from ejaculation for 3 days before undergoing uroflowmetry (UF1). Subsequently, they were required to ejaculate. Subsequent uroflowmetry assessments were conducted at 2 to 4 h (UF2) and 48 to 50 h (UF3) after ejaculation. No further ejaculations were permitted during this timeframe. Results: The patients had a mean age of 50.97 ± 1.47 years. Statistically significant differences were observed in the mean values of Qmax and corrected Qmax (cQmax) between UF1 and UF2 measurements (p < 0.05). These differences were only in patients with benign prostatic enlargement (BPE) (p < 0.05). Furthermore, the number of patients with Qmax <15 mL/s showed a statistically significant difference between UF1 and UF2 measurements, specifically in the BPE group (p = 0.016). Conclusions: In this study, we have observed a significant and temporary increase in the Qmax following ejaculation, particularly among patients with BPE. This indicates that ejaculation can potentially complicate the interpretation of uroflowmetry results. Therefore, further research is necessary to gain a more comprehensive understanding of this phenomenon. © 2024 Wiley Periodicals LLC.
