Association between benign prostatic hyperplasia,body mass index,and metabolic syndrome in Chinese men

Previous studies have showed that men suffering from diabetes mellitus, metabolic syndrome (MetS) and obesity have a higher risk of benign prostatic hyperplasia (BPH). The present study aimed to examine the association between BPH, obesity, and features of MetS among men of the Hunan area of China. For this cross-sectional study, 904 males (aged 50–59 years) were included. MetS parameters, International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA) levels, total prostate volume (TPV), postvoid residual volume (PVR) and maximum urine flow rate (Qmax) were measured. Results showed that MetS was associated with TPV (P = 0.048), PVR (P = 0.004) and IPSS (P = 0.011), but not with other indicators of BPH progression such as PSA levels or Qmax. MetS was associated with the voiding symptoms score (P < 0.05), but not with the storage symptom score. In addition, body mass index and fasting blood glucose positively correlated with TPV (r = 0.416, P < 0.001; and r = 0.310, P= 0.011, respectively). In conclusion, results suggest that MetS is associated with higher prostatic volume, prostate symptom score and voiding symptoms, but not with other features of prostatic hyperplasia such as PSA levels or Qmax. Changes in lifestyle factors, including physical activity and prevention of MetS, might be useful to prevent BPH and its progression, but further studies are needed.     

Can preoperative detrusor underactivity influence surgical outcomes of 120 W HPS vaporization of the prostate (PVP) or holmium laser enucleation of the prostate (HoLEP)? A serial 3‐year follow‐up study

Aims

To determine the influence of preoperative detrusor underactivity (DU) on serial long‐term outcomes of HPS/PVP or HoLEP for LUTS/BPH, and to compare the influence between the two surgeries.

Methods

A total of 382 men, who underwent 120W‐HPS/PVP or HoLEP for LUTS/BPH and for whom 36‐month follow‐up data were available, were classified into four groups: HPS with DU (n = 145), HPS without DU (n = 44), HoLEP with DU (n = 105), and HoLEP without DU (n = 88). DU was defined as bladder contractility index of <100. Surgical outcomes were assessed at postoperative 6, 12, 24, and 36 months using IPSS, uroflowmetry, and serum PSA.

Results

All four groups maintained improvements in voiding symptom score (VSS), storage symptom score, total‐IPSS, QOL index, maximum flow rate (Qmax), post‐void residual urine volume (PVR), and bladder voiding efficiency (BVE) compared with baseline up to 3 years postoperatively. There were no significant differences in improvements of postoperative IPSS parameters including QOL index between men with and without DU throughout the follow‐up period after HPS or HoLEP. In men with DU, there were no significant differences in improvements of postoperative QOL index, Qmax, PVR, or BVE between HPS and HoLEP groups throughout the follow‐up period, except for VSS and total IPSS. Serum PSA reductions after HoLEP were greater than after PVP.

Conclusions

Improvements in LUTS, Qmax, and BVE can maintain up to 3 years after HPS or HoLEP for LUTS/BPH, irrespective of the presence or absence of preoperative DU. Although HoLEP may provide more durable improvement of VS in men with DU than HPS, there seems to be no difference in improvement of QOL or Qmax or BVE between HPS and HoLEP.

Efficacy and safety of combination therapy with mirodenafil and α1-blocker for benign prostatic hyperplasia-induced lower urinary tract symptoms accompanied by erectile dysfunction: a multicenter, open-label, prospective study

This study was conducted to determine whether mirodenafil 100 mg, when administered on demand to patients with benign prostatic hyperplasia (BPH) who are receiving α1-blocker therapy, is safe with regard to the cardiovascular system and whether it improves lower urinary tract symptoms (LUTS) and sexual function. The study involved 121 LUTS/BPH patients who had been treated for at least 3 months with α1-blockers before being administered with mirodenafil 100 mg on demand. Before the start of mirodenafil administration, the blood pressure, heart rate, international prostate symptom score (IPSS)/quality of life (QoL), peak urine flow rate (Qmax), post-voiding residual urine volume (PVR), and international index of erectile function-5 (IIEF-5) of each patient were measured. At 4 and 8 weeks after commencing mirodenafil administration, the blood pressure and heart rate were measured again, any adverse effects of mirodenafil were assessed, and sexual function and voiding symptoms were re-evaluated. Of the 121 patients, 73 (60.3%) completed the 8-week clinical trial. Significant changes in blood pressure and heart rate were not observed during the study. Significant improvements in the IIEF-5 and the IPSS/QoL, but not the Qmax or PVR, were observed. The results of this study suggest that the administration of mirodenafil 100 mg on demand may induce few hypotensive interactions and may be acceptably effective with regard to improving LUTS and sexual function.

Clinical effects of naftopidil on nocturia associated with benign prostatic hyperplasia

We studied the efficacy of naftopidil (50 mg/day) on nocturia associated with benign prostatic hyperplasia in 35 patients (62-80 years old). The patients had BPH > 20 ml, nocturia, more than 3 times, international prostate symptom score (IPSS) > 7, quality of life score (QOL) < 1, and maximum flow rate (Qmax) < 15 ml/sec. They received naftopidil for more than 6 weeks. IPSS, QOL, Qmax, micturition volume, and side effects were analyzed. Naftopidil was effective for nocturia associated with benign prostatic hyperplasia, especially when taken at night.     

Clinical evaluation of supplemental administration of flavoxate hydrochloride in benign prostatic hyperplasia patients with nocturia resistant to an alpha1-adrenoceptor blocker

We examined the effectiveness of supplemental administration of flavoxate hydrochloride in patients with benign prostatic hyperplasia (BPH) whose nocturia was not adequately relieved by an alpha1-adrenoceptor blocker. Fifty-two patients who had two or more nocturnal micturition after administration of tamsulosin hydrochloride or naftopidil for 4 weeks or more received 400-600 mg of flavoxate hydrochloride in addition to an alpha1-adrenoceptor blocker for another 8-12 weeks. With supplemental administration of flavoxate hydrochloride, significant improvement was observed in the number of nocturnal micturition, total International Prostate Sympton Score, quality of life score and BPH impact index. No significant change was observed in the voided volume, Qmax, voiding time and residual urine volume. Supplemental administration of flavoxate hydrochloride is therefore effective for the improvement of nocturia and QOL in BPH patients resistant to an alpha1-adrenoceptor blocker.     

Combination of alfuzosin and sildenafil is superior to monotherapy in treating lower urinary tract symptoms and erectile dysfunction

OBJECTIVES: This pilot study was undertaken to assess the efficacy and safety of the alpha(1)-blocker alfuzosin 10mg once daily (OD), the PDE-5 inhibitor sildenafil 25mg OD, and the combination of both on lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). MATERIAL AND METHODS: Men aged 50-76 yr with previously untreated LUTS and ED were randomized to receive alfuzosin (n=20), sildenafil (n=21), or the combination of both (n=21) for 12 wk. Changes from baseline in International Prostate Symptom Score (IPSS), voiding diary, maximum urinary flow rate (Qmax), postvoid residual urine (PVRU) volume, and erectile function domain of the International Index of Erectile Function (IIEF) were assessed at week 12. RESULTS: Improvement of IPSS was significant with the three treatments but greatest with the combination (-24.1%) compared with alfuzosin (-15.6%) and sildenafil (-11.8%) [corrected] alone (p<0.03). Frequency, nocturia, PVR, and Qmax were significantly improved with alfuzosin only and the combination. Improvement in IIEF was slight with alfuzosin (16.7%), marked with sildenafil (49.7%), and greatest with the combination (58.6%). Likewise, increases in the frequency of penetration (Q3) and of maintained erection (Q4) were greater with the combination therapy (65.2% and 68.2%, respectively) than with sildenafil (41.7% and 59.1%, respectively) and alfuzosin (27.3% and 33.3%, respectively) alone. All three treatments were well tolerated. CONCLUSIONS: In this pilot study, the combination of alfuzosin 10 mg OD and sildenafil 25 mg OD is safe and more effective than monotherapy with either agent to improve both voiding and sexual dysfunction in men with LUTS suggestive of BPH.     

Plasma kinetic vaporization of the prostate: clinical evaluation of a new technique

PURPOSE: We evaluated our results with bipolar plasma kinetic electrovaporization in the treatment of benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Twenty-one patients with infravesical obstruction by BPH have been treated with bipolar plasma kinetic electrovaporization. International Prostate Symptom Score (IPSS) with a quality of life (QOL) scoring questionnaire, uroflowmetry (maximum flow rate; Qmax), transrectal ultrasonography (TRUS), and residual urine volume and prostate specific antigen (PSA) measurements had been performed before surgery. The IPSS scores, prostate volumes, and residual urine volumes were reevaluated during the third postoperative month. Uroflowmetry was repeated on postoperative days 7, 15, 30, and 90. Total PSA and free PSA measurements were repeated on postoperative days 3, 5, 7, 15, 30, and 90. RESULTS: The results of 20 patients could be evaluated. The median age of these patients was 61 years. The median volume of the prostates was 42 cc (95% CI 56-53). The median operation time and postoperative hospitalization were 55 minutes (95% CI 40-65) and 3 days (95% CI 3-5), respectively. The mean period of time needed for vaporizing 1 g of tissue was calculated as 2.8 +/- 1.3 minutes. Postoperative day 90 values of IPSS, QOL, prostate volume, residual urine volume, and Qmax showed significant improvement compared with preoperative values (p < 0.05). The median preoperative PSA value was 1.64 mg/mL (95% CI 1-3.6). The value showed a statistically significant increase 24 hours after the intervention (p < 0.0001), but the PSA values on the 30th (p = 0.041) and 90th (p = 0.025) days were below preoperative values. CONCLUSION: The IPSS with QOL scores, prostate volumes, and residual urine volumes showed significant decreases and Qmax values showed a significant increase after bipolar plasma kinetic electrovaporization. This treatment modality causes a temporary increase in the PSA concentration, as do other interventional treatment methods, but the measurements on the 30th and 90th days were below preoperative values.     

Surgery (TUR-P) as a recommended initial treatment modality for the presented case

The pathophysiology of lower urinary tract dysfunction in the presented case comprised voiding dysfunction and overactive bladder. Two etiologies for voiding dysfunction in this case could be considered, bladder outlet obstruction due to benign prostatic hyperplasia (BPH) or detrusor underactivity. Prospected efficacies of pharmacological and surgical treatment (transurethral resection of prostate: TUR-P) for this case were compared based on a literature review. Alpha-1 blockers improve both voiding and storage symptoms in patients with BPH. However, improvement of maximum flow rate (Qmax) on uroflowmetry is limited within a small range and there is no evidence of significant reduction in residual urine volume. Alpha-1 blockers have no significant efficacy in improvement of objective measures in patients with detrusor underactivity. Although anticholinergics improve overactive bladder symptoms, they are contraindicated for patients with severe voiding dysfunction with residual urine. There is a lack of study on efficacy of apha-1 blocker administration combined with anticholinergics available in our hands for patients with BPH and overactive bladder. On the other hand, TUR-P brings remarkable improvement in voiding and storage symptoms, increase of flow rate and reduction of residual urine as a gold-standard surgical treatment for BPH. Urge incontinence and uninhibited detrusor contraction on cystometry reportedly disappeared in 60% of patients following TUR-P. TUR-P also improves subjective symptom and objective measures in patients with BPH and detrusor underactivity. Based on the literature review, surgery is recommended as a standard initial therapy for the presented patient with significant voiding dysfunction (Qmax 9.4 ml/sac and residual urine 72 ml).     

Roles of BPH impact index in the evaluation of impaired urination in patients with BPH

OBJECTIVE: To assess the significance and current status of the benign prostatic hyperplasia (BPH) impact index (BII) in the evaluation of subjective symptoms of impaired urination in so-called QOL disease, BPH. PATIENTS AND METHODS: Over the past 2 year-period, in 159 patients with the diagnosis of BPH were asked to reply to each of the international prostate symptom score (I-PSS), QOL index and BII questionnaires. The subjective symptom scores (a total of 246 points) were evaluated from the viewpoint of clinical statistics in the search for any these and to find which questions cover the BII, most. RESULTS: 1) Statistically significant but moderate correlations were observed among I-PSS total score, QOL index and BII. The correlations among Qmax, BII and QOL were very weak. 2) Out of the 11 domains in both IPSS and BII, 2 questions of BII ("bothersomeness caused by urinary problems" and "degree of worry about well-being") and 4 questions of IPSS ("residual sense," " pollakisuria," "weak urinary stream" and "nocturia") were shared as QOL indices. Patient satisfaction was affected also by the questions in the BII. 3) Of the 7 BPH symptoms assessed in IPSS, 4 symptoms ("residual sense," "pollakisuria," "weak urinary stream" and "nocturia") affected the QOL index, and 4 symptoms ("urgency on micturition," "residual sense," "nocturia" and "strain at urination") affected BII. 4) Of the 7 symptoms assessed by IPSS, different symptoms affected each of the 4 BII questions. CONCLUSION: It is needed to assess BPH symptoms not only by the IPSS and QOL index but also based on BII to provide the detailed therapeutic instructions and thorough patients consultation.

Efficacy of transurethral needle ablation of the prostate for the treatment of benign prostatic hyperplasia

BACKGROUND: We evaluated the efficacy and safety of transurethral needle ablation (TUNA) of the prostate for treatment of symptomatic benign prostatic hyperplasia (BPH) as one institute participating in a Japanese clinical trial. METHODS: Thirty-three patients with symptomatic BPH were treated with the TUNA procedure in our institute. The international prostate symptom score (IPSS), quality of life (QOL) score, residual urine volume (RV), prostate volume (PV) and peak urinary flow rates (Qmax) were measured and complications were assessed. RESULTS: We followed and evaluated 30 of the 33 cases. At 12 months there were significant improvements in the IPSS (20.7 to 11.2, P < 0.0001), QOL score (4.9 to 2.1, P < 0.0001), RV (46.6 to 22.6 mL, P < 0.01), PV (37.8 to 30.0 mL3, P < 0.002) and Qmax (8.00 to 11.0 mL/s, P < 0.002). There were no serious complications. CONCLUSION: This trial shows that the TUNA procedure is a safe and efficacious treatment for symptomatic BPH.     

Prognostic value of a combination of IPSS,flow rate and residual urine volume compared to pressure-flow studies in the preoperative evaluation of symptomatic BPH

OBJECTIVE: Evaluate the predictive value of a combination of IPSS, uroflowmetry and ultrasound determination of residual urine volume in the determination of bladder outflow obstruction (BOO) and in predicting treatment outcome. METHODS: Forty-five out of a group of 60 BPH symptomatic patients were included. Preoperative evaluation: urine culture, PSA, uroflowmetry with sonographic measurement of post-void residual urine, DRE, IPSS with quality of life questions and pressure-flow study. Selection criteria for surgery were IPSS > 16 and Qmax < 10 ml/s. Transurethral resection of the prostate was performed in these patients; the control visit was performed at 3 months. Treatment success was defined as Qmax above 15 ml/s, residual urine of less than 100 ml, a 50% reduction in IPSS and absence of urinary retention. RESULTS: Urodynamic abnormalities were found in 42 patients (93.3%): 19 had detrusor instability, 5 patients showed impaired contractility, 37 patients had proven BOO, and 8 patients were unobstructed or mildly obstructed. The overall success rate was 86% when measured by the IPSS. Its preoperative value was 16.9, and dropped significantly to 4 (P = 0.005). The score improved significantly after surgery only in the obstructed group compared to the non-obstructed group (P = 0.001), however preoperative IPSS did not correlate with objective treatment results. CONCLUSIONS: A high proportion of patients successfully operated (71.1%) had a combination of IPSS > 16 and Qmax < 10 ml/s, although BOO could not be accurately predicted with non-invasive methods alone. Patients with no or mild infravesical obstruction had only minimal improvement of IPSS and uroflowmetry following surgery.
