Maximum Urinary Flow

Because various criteria are used to define metabolic syndrome (MetS), this study examines the most relevant definition for patients with benign prostatic enlargement (BPE). Most studies regarding the link between MetS and BPE/lower urinary tract symptoms (LUTS) have used the National Cholesterol Education Program Adult Treatment Panel III criteria for diagnosis, while a few have used criteria from the International Diabetes Federation and/or American Heart Association. Patients with LUTS due to BPE are classified as having MetS or not by the aforementioned three definitions. Prostate volume, International Prostate Symptom Score, storage and voiding subscores, maximum urinary flow rate, and the postvoid urine of patients with and without MetS were compared separately in the three different groups. Surgical and medical treatment prevalence was also compared between three groups. No matter which definition was used, the International Prostate Symptom Score, the storage and voiding symptom scores, prostate volume, prostate-specific antigen, and postvoid urine were significantly higher in the patients with MetS. The maximum urinary flow rate was similar between patients with and without MetS, according to all three different definitions. There was no significant difference in the aforementioned parameter between patients with MetS diagnosed with the three different definitions. Irrespective of which definition was used, the surgical treatment rate was not significantly different in patients diagnosed with than without MetS, or between the patients with MetS diagnosed with the three different definitions. The authors suggest that it does not matter which of the aforementioned three definitions is used during the evaluation of MetS in men with BPE/LUTS.

The objective of this study was to evaluate association between body mass index (BMI) and prostate volume (PV), international prostate symptom scores (IPSS), maximum urinary flow rate ( Qmax), and post-void residual (PVR) of Chinese benign prostatic hyperplasia (BPH) patients. All newly diagnosed BPH patients between September 2016 and August 2018 were selected and 788 patients were included. According to BMI, the patients were categorized into four groups, while according to PV, IPSS, Qmax, and PVR, they were categorized into two groups based on clinical significant cutoffs. Univariable and multivariable logistic regressions and a restricted cubic spline (RCS) were applied to explore the relationship of BMI with categorical PV, IPSS, Qmax, and PVR. Compared with normal BMI, obesity presented significant association with increased risk of larger PV (>80 ml) in both unadjusted and adjusted models (unadjusted odds ratio [OR] = 1.772, 95% CI [1.201, 2.614], p = .004; adjusted OR = 1.912, 95% CI [1.212, 3.017], p = .005); however, underweight or overweight did not present a significant connection with such risk. No significant effect was identified for BMI on IPSS, Qmax, or PVR in either unadjusted or adjusted model. Nonlinear test including BMI using RCS and adjusting for confounders showed no significance ( p > .05); however, a significant linear relationship was ascertained between BMI and the risk of larger PV ( p < .001). In conclusion, there was a significant linear association between BMI and the risk of larger PV in BPH patients. Hence, this suggests urologists should consider both BMI and PV when providing surgical treatment for BPH patients.

Objective: T0 compare the outcome of Transurethral Resecton of Prostate between Patients with Preoperative Low or Normal and High Voiding Pressure. Methods: This hospital based prospective observational study was conducted in the Department of Urology of Dhaka Medical college Hospital from July 2008 to June 2010 on male patients aging >59 years having Lower urinary tract symptoms (LUTS) attending to urology OPD& IPD were evaluated by history, physical examination including DRE and necessary investigations like USG of KUB and prostate with MCC & PVR, Q max, IPSS score to identify the potential candidates for TURP. Potential participants were counseled for urodynamic study. Who fulfilled the selection criteria included in this study in outpatient basis or admitted in the urology ward and numbered chronologically and performed urodynamic study and then patients underwent TURP, after 12 weeks of completion of TURP again a follow-up urodynamic study performed in all patients to compare the outcome between two groups. Sample size was 65, high pressure voiding group were 36 in number and Normal or low pressure voiding group were 29 in number. Data were collected on variables of interest using a structural data collection format. Data were processed and analyzed using SPSS (Statistical package for social science) software program. The test of significant employed to analyze the data was descriptive statistics and Student’s t-test, Paired and unpaired t- test, Fisher exact test. Probability value (P value < 0.05) was considered significant. Results: In this study the age ranges were 59 and 88 years and mean age was 70.7 ± 6.7 years. the maximum urinary flow rate, residual urine volume and maximum intravesical pressure 3 months after transurethral prostatic resection were significantly better in patients with high detrusor pressure compared to those with normal/low normal/low detrusor pressure (15.9±0.7 vs. 21.3±2.2ml/sec, p<0.001, 18.1±11.8 vs. 2.9±0.7 ml, p<0.001 and 48.3±6.2 vs. 71.9±15.2 cmH2O, p<0.001 respectively).The maximum urinary flow rate ( Q max ), residual urine volume, maximum intravesical pressure and detrusor pressure at peak urinary flow rate and also IPSS score were significantly improved 3 months after operation in both groups, more improvement was observed in preoperative high voiding pressure group. Post-voiding residual urine is a clear indication of poor outcome, and also the maximum urinary flow rate, maximum intravesical pressure and detrusor pressure at peak urinary flow rate all factors may precipitate decompensation of bladder and in low voiding pressure group decompensation of bladder occurs more than the high voiding pressure group as the preoperative and postoperative residual urine develops more in low voiding pressure group. Conclusion: The high voiding pressures (detrusor pressure) may influence in good postoperative outcome and helps in resolution of a significant outflow obstruction, there are good urodynamic reasons for avoiding unwanted TURP rather it could be justified by using urodynamic study which may predict outcome of TURP. So, we may assess properly the patient for prostatectomy by urodynamic study. As if we do this type of evaluation before TURP it may reduce the unwanted operation.
