Post-Voided Residual Ratio Does Not Predict Trifecta Outcome after Transurethral Resection of Prostate. Life (Basel) 2024; 14:445. [PMID: 38672716 PMCID: PMC11051523 DOI: 10.3390/life14040445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 03/25/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
The purpose of this study was to assess the importance of the post-void residual (PVR) ratio (PVR ratio) in achieving a favorable trifecta outcome for patients suffering from lower urinary tract symptoms and benign prostatic enlargement (LUTS-BPE) who undergo transurethral resection of the prostate (TURP). Starting from 2015, a series of patients with LUTS-BPE who underwent TURP were included in a forward-looking study. These patients were assessed using the international prostate symptom score (IPSS) screening tool, uroflowmetry, and a transrectal ultrasound to measure prostate volume (TRUS). Both the PVR urine volume and the PVR ratio (PVR-R), which is the PVR as a percentage of total bladder volume (voided volume + PVR), were measured. The assessment of outcomes was based on the trifecta favorable outcome, defined as meeting all of the following criteria: (1) absence of perioperative complications, (2) a postoperative IPSS of less than eight, and (3) a postoperative maximum urinary flow rate (Qmax) greater than 15 mL/s. A total of 143 patients were included, with a median age of 70 years (interquartile range 65-73). Of these, 58% (83/143) achieved a positive trifecta outcome. Upon conducting a multivariate analysis, both IPSS and Qmax were identified as predictors of a positive trifecta outcome, whereas the PVR-R did not prove to be an independent predictor. In summary, it was found that preoperative IPSS and Qmax are indicative of a trifecta outcome following TURP, whereas PVR-R is not.

Abstract
Background The correlation between modified bladder outlet obstruction index (MBOOI) and surgical efficacy still remains unknown. The purpose of the study was to investigate the clinical value of the MBOOI and its use in predicting surgical efficacy in men receiving transurethral resection of the prostate (TURP).
Methods A total of 403 patients with benign prostate hyperplasia (BPH) were included in this study. The International Prostate Symptom Score (IPSS), quality of life (QoL) index, transrectal ultrasonography, and pressure flow study were conducted for all patients. The bladder outlet obstruction index (BOOI) (PdetQmax–2Qmax) and MBOOI (Pves–2Qmax) were calculated. All patients underwent TURP, and surgical efficacy was accessed by the improvements in IPSS, QoL, and Qmax 6 months after surgery. The association between surgical efficacy and baseline factors was statistically analyzed. Results A comparison of effective and ineffective groups based on the overall efficacy showed that significant differences were observed in PSA, Pves, PdetQmax, Pabd, BOOI, MBOOI, TZV, TZI, IPSS-t, IPSS-v, IPSS-s, Qmax, and PVR at baseline (p < 0.05). Binary logistic regression analysis suggested that MBOOI was the only baseline parameter correlated with the improvements in IPSS, QoL, Qmax, and the overall efficacy. Additionally, the ROC analysis further verified that MBOOI was more optimal than BOOI, TZV and TZI in predicting the surgical efficacy. Conclusion Although both MBOOI and BOOI can predict the clinical symptoms and surgical efficacy of BPH patients to a certain extent, however, compared to BOOI, MBOOI may be a more useful factor that can be used to predict the surgical efficacy of TURP. Trial registration retrospectively registered.

Abstract
Lower urinary tract symptoms (LUTS) are common in males over the age of 40 years old and are likely to increase with an aging population. Currently urodynamic studies are the gold standard to determine the aetiology of voiding dysfunction and LUTS. However, due to its invasive nature, a great number of non-invasive ultrasound based investigations have been developed to assess patients with symptomatic LUTS. The clinical application of non-invasive tests could potentially stratify patients who would require more invasive investigations and allow more precise patient directed treatment. A PubMed literature review was performed and we will discuss the non-invasive investigations that have been developed thus far, focusing on bladder wall and detrusor wall thickness (BWT & DWT), ultrasound estimated bladder weight (UEBW) and intravesical prostatic protrusion (IPP).

Abstract
PURPOSE To investigate the association of prostate blood flow (PBF) with lower urinary tract symptoms (LUTS) in aged males using Doppler spectral waveform (DSW) analysis. PATIENTS AND METHODS We performed a prospective analysis involving 133 aged males with clinical diagnosis of LUTS. DSW parameters (peak-systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI)) were measured at bilateral neurovascular bundles (NVB), periurethral, and capsular branches by Doppler transrectal ultrasound with the patient in the right lateral decubitus position. The associations of PBF parameters and the International Prostate Symptom Score (IPSS) were analyzed. RESULTS Overall, total IPSS scores were significantly correlated with the RI of bilateral NVB vessels (r2 = 0.03, 0.04; p = 0.04, 0.02, respectively), and PSV of left NVB vessels. PSV of bilateral NVB vessels were associated with the storage score (p = 0.022 and p = 0.016), but not with the voiding score. The sum of the frequency and urgency score was also associated with EDV of both capsular and urethral branches (p = 0.043 and p = 0.009, respectively), and PSV of NVB vessels on both sides (p = 0.045 and p = 0.019, respectively). CONCLUSIONS There is an association between PBF and LUTS, especially with storage symptoms. The findings may provide some insights in understanding the underlying pathophysiology of lower urinary tract dysfunction.

Abstract
OBJECTIVES To examine which parameters obtained from transrectal ultrasonography are accurate predictors of urodynamically-confirmed bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. METHODS The records of 350 patients with complaints of lower urinary tract symptoms suggestive of benign prostatic hyperplasia were reviewed. Baseline parameters were international prostate symptom score, quality of life score, postvoid residual urine volume, prostate-specific antigen, and data obtained from uroflowmetry and transrectal ultrasonography. Urodynamic studies were carried out to determine bladder outlet obstruction. Receiver operator characteristic curves were generated to compare the accuracy of the different parameters, and the area under the curve of each parameter was calculated. RESULTS Bladder outlet obstruction index positively correlated with intravesical prostatic protrusion, total prostate volume, transition zone volume, transition zone index, resistive index and prostate-specific antigen. Further, resistive index was only a significant independent variable with intravesical prostatic protrusion. Intravesical prostatic protrusion had the highest area under the curve of 0.790 among all variables, and its cut-off value was 10 mm. The positive predictive value of intravesical prostatic protrusion was 76.2%. In addition, the positive predictive value of the combined parameters intravesical prostatic protrusion and resistive index increased to 83.8%. CONCLUSIONS Intravesical prostatic protrusion and resistive index are useful parameters for predicting bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. In clinical practice, the combination of intravesical prostatic protrusion and resistive index on ultrasound can be diagnostic of bladder outlet obstruction.

Abstract
OBJECTIVES To establish and to evaluate discriminant models to predict the outcomes of transurethral prostatectomy. METHODS Clinical data of patients treated with transurethral prostatectomy between January and December 2013 were collected, including medical history, symptoms, biochemical tests, ultrasonography and urodynamics. Surgical efficacy was evaluated at 6-month follow up. Predictive models were constructed by logistic regression. Receiver operating characteristic curve and diagnostic tests were used to test the accuracy of models before the predictive value between models was compared. RESULTS A total of 182 patients were included, with 73.6% having an effective outcome. History of recurrent urinary tract infection (OR 1.33), score of storage phase (OR 2.58), maximum flow rate (OR 2.11) and detrusor overactivity (OR 3.13) were found to be risk factors. International Prostate Symptom Score (OR 0.13), transitional zone index (OR 0.58), resistive index of prostatic artery (OR 0.46), bladder wall thickness (OR 0.78), ultrasonic estimation of bladder weight (OR 0.28), bladder outlet obstruction index (OR 0.20) and bladder contractility index (OR 0.83) were found to be protective factors. The areas under the curve of models using factors from ultrasonography and urodynamics were 0.792 and 0.829 respectively, with no significant difference being found between them (P = 0.348). CONCLUSIONS Surgical efficacy of transurethral prostatectomy is positively correlated to severe voiding phase symptoms, outlet obstruction and better detrusor contractility, and negative correlated with urinary infection, severe storage phase symptoms and excessive detrusor contractibility. Ultrasonography might replace urodynamics in selecting patients for whom transurethral prostatectomy is more likely to be beneficial.

Abstract
We evaluated the relationship between prostatic resistive index (RI) and cardiovascular system (CVS) risk factors in patients with benign prostatic hyperplasia. The study included 120 patients who were attending our outpatient clinic with lower urinary tract symptoms related to benign prostatic hyperplasia. The clinical, laboratory, anthropometric data, and CVS risk factors (hypertension, diabetes mellitus, metabolic syndrome, history of CVS events, and smoking) of the patients were evaluated regarding the association between prostate RI level by regression analyses. The prostatic RI levels of the patients were measured using power Doppler imaging. In univariate regression analysis, there were statistically significant relationships between prostatic RI levels and the patients' age, International Prostate Symptom Score, hip circumference, fasting blood glucose, prostate specific antigen, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total prostate volume, uroflowmetric maximal flow rate, and all investigated CVS risk factors (p < 0.05). The prostatic RI levels were found to be associated with fasting blood glucose and total prostate volume, and also with CVS risk factors including only metabolic syndrome and cigarette smoking in the multivariate regression analysis. Our results showed that prostatic RI level is significantly related to metabolic syndrome and smoking among the investigated CVS risk factors.

Abstract
INTRODUCTION The effects of medical therapy or surgery on bladder and prostatic resistive indices (RIs) in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) were evaluated in the present study. PATIENTS AND METHODS A total of 124 consecutive LUTS/BPH patients who were candidates for medical therapy (alfuzosin 10 mg once daily, n=66) or surgery (transurethral prostatectomy (TUR-P), n=58) were prospectively included. Baseline assessment of patients was performed with the International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), and prostatic and bladder RIs measured using power Doppler imaging (PDI). All patients were re-evaluated 3 months after treatment measuring the same parameters. RESULTS Following medical therapy, mean IPSS (17.2±5.1 vs. 8.3±5.3, p=0.0001), postvoiding residual (PVR) urine (80.0±80.5 vs. 40.3±38.6, p=0.0001), and prostatic RI (0.73±0.1 vs. 0.70±0.1, p=0.0001) were decreased, Qmax (13.7±4.2 vs. 16.9±5.9, p=0.0001) was increased, and bladder RI remained unchanged (0.70±0.1 vs. 0.70±0.1, p=0.68). Mean IPSS (25.3±5.6 vs. 6.0±4.5, p=0.0001), PVR urine volume (134.5±115.5 vs. 35.7±25.9, p=0.0001), and prostatic (0.78±0.1 vs. 0.67±0.04, p=0.0001) and bladder RIs (0.72±0.1 vs. 0.64±0.04, p=0.005) were decreased, and Qmax (8.0±4.5 vs. 17.2±8.2, p=0.0001) was increased after TUR-P. CONCLUSIONS Our results demonstrated that TUR-P decreased both prostatic and bladder RIs, while α-blocker therapy did not change bladder RI in the early posttreatment period in LUTS/BPH patients.

Abstract
OBJECTIVES To evaluate the value of three parameters from preoperative ultrasonography in predicting the outcome of transurethral prostatectomy in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction. METHODS A total of 239 patients with lower urinary tract symptoms suggestive of benign prostatic obstruction entering our department for surgical therapy were prospectively recruited. All of them underwent both ultrasound and urodynamics before receiving standard transurethral prostatectomy by the same team of surgeons. For 202 patients, 6-month follow-up data were available after the surgery, including the International Prostate Symptom Score, the Quality of Life score and the maximum flow rate. Preoperative data stratified by different degree of recovery were compared and the influence of ultrasound parameters on the surgical outcome was analyzed by using logistic regression and receiver-operator characteristic curve analyses. RESULTS Baseline transitional zone index, intravesical prostatic protrusion, resistive index, detrusor wall thickness and ultrasonic estimation of bladder weight were significantly different between patients with an effective outcome and those with an ineffective outcome (P < 0.05). Resistive index, detrusor wall thickness and ultrasonic estimation of bladder weight were selected as independent factors correlated with the efficacy of transurethral prostatectomy by logistic regression (P < 0.05). All three factors had adequate area under receiver-operator characteristic curve with resistive index having the largest area (0.816, 95% CI 0.759-0.874). The combined positive predictive value in effective surgical outcome of resistive index, detrusor wall thickness and ultrasonic estimation was 96.3%. CONCLUSIONS Resistive index, detrusor wall thickness and ultrasonic estimation adequately predict the outcome of transurethral prostatectomy. Measuring these parameters by preoperative ultrasound might aid in determining the need for surgical intervention.

Abstract
Benign prostatic hyperplasia (BPH) is an extremely common and chronic condition that can lead to bladder outlet obstruction (BOO) in elderly men. Although pressure-flow studies are considered the most reliable method for evaluating BOO, they are invasive and complicated. Transrectal ultrasonography (TRUS) is a promising alternative because of its minimal invasiveness. Recently, TRUS imaging has been shown capable of measuring the resistive index, a useful parameter for evaluating BOO and for determining proper medical intervention in patients suffering from BPH.
