RESUMO
PURPOSE: This five-year, retrospective, multicenter study evaluated the long-term safety and efficiency of sacral neuromodulation (SNM) in Chinese patients with urinary voiding dysfunction. PATIENTS AND METHODS: This is a Chinese national, multicenter, retrospective study that included 247 patients (51.2% female) who received an implantable pulse generator (IPG) (InterStim, Medtronic, Minneapolis, MN, USA) between 2012 and 2016. Success was considered if the initial ≥50% improvement in any of primary voiding diary variables persisted compared with baseline. The results were further stratified by identifying patients who showed >50% improvement and those although showed <50% improvement but still wanted to receive IPG; these data were collected and analyzed for general improvement. RESULTS: Following test stimulation, 187 patients (43%) declined implantation and 247 (57%) underwent implantation using InterStim®. Among 247 patients, 34 (13.7%) had overactive bladder (OAB), 59 (23.8%) had interstitial cystitis/bladder pain syndrome (IC/BPS), 47 (19%) had idiopathic urinary retention (IUR), and 107 (44.1%) had neurogenic bladder (NB). IPG efficiency rate for OAB, interstitial cystitis/bladder pain syndrome, idiopathic urinary retention, and neurogenic bladder were 42.5, 72.4, 51.6, and 58.8%, respectively. The mean duration of follow-up was 20.1 ± 12.8 months. CONCLUSIONS: SNM appears effective in the long term, with a total IPG implantation rate of approximately 57% (ranging between 42.5 and 72.4% depending on indication). Interstitial cystitis/bladder pain syndrome appear to be the best indication for stage I testing. Chinese neurogenic bladder patients are most inclined to choose SNM. SNM is relatively safe, with low postoperation adverse events of 16.1% and reoperation rate of 3.2% during the follow-up period.

OBJECTIVE: To evaluate the efficacy of Huang'e Capsules in the treatment of BPH of the qi-deficiency blood-stasis and damp-heat stagnation type under conditions of extensive use. METHODS: Totally, 605 male patients with BPH of the qi-deficiency blood-stasis and damp-heat stagnation type received oral Huang'e Capsules, tid, 4 capsules per time, for 42 days. We recorded the IPSS, maximum urinary flow rate (Qmax), mean urinary flow rate (Qave), quality of life (QOL) score, and prostate volume of the patients before and after medication. RESULTS: A total of 503 patients completed the whole trial. Compared with the baseline, the patients showed significant decreases after treatment in the IPSS (20.1 ± 5.5 vs 12.6 ± 5.0, P < 0.05), QOL score (4.19 ± 0.90 vs 2.50 ± 0.89, P < 0.05) and prostate volume (ï¼»36.6 ± 15.8ï¼½ vs ï¼»34.0 ± 17.6ï¼½ ml, P < 0.05), but remarkable increases in Qmax (ï¼»12.2 ± 5.8ï¼½ vs ï¼»14.2 ± 6.5ï¼½ ml/s, P < 0.05) and Qave (ï¼»5.91 ± 3.12ï¼½ vs ï¼»6.95 ± 3.45ï¼½ ml/s, P < 0.05). CONCLUSIONS: Huang'e Capsules had a good therapeutic effect on BPH of the qi-deficiency blood-stasis and damp-heat stagnation type.

OBJECTIVES: The present work evaluated preventive effect of curcumin on cisplatin-induced bladder cystopathy. METHODS: Fifteen female rats were divided into (i) Control group administered with physiological saline solution for 5 days; (ii) Cis-P group injected with cisplatin (6 mg/kg); and (iii) Cis-Cur group given cisplatin (6 mg/kg) with curcumin for 5 consecutive days. The function of bladder was measured by means of urodynamic analysis. Furthermore, hematoxylin-eosin staining and Masson trichrome staining were performed for morphological analysis. The cell apoptosis was evaluated through terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay and flow cytometry. The expression of nerve growth factor (NGF), NF-E2-related factor 2, and hemeoxygenase-1 (HO-1) levels were measured through Western blotting. RESULTS: Urodynamic assay and histopathological manifestations revealed that curcumin ameliorated the bladder dysfunction induced by cisplatin. The level of cisplatin-induced apoptosis in the bladder decreased following curcumin treatment. Also, the increased protein expression of NGF indicated that the curcumin could offer neuroprotection for bladder against cisplatin. Curcumin also activated NRF2, and elevated the expression of HO-1, but curcumin could not rescue cisplatin-induced apoptosis in the cell lines with knockdown of NRF2. CONCLUSIONS: Taken together, the results of this paper showed that curcumin could ameliorate cisplatin-induced cystopathy and inhibit the apoptosis of bladder cell in cisplatin-treated rats. This may be attributed to curcumin's broad biological functions, particularly antioxidant effect, and to its ability to activate the NRF2 protein.

OBJECTIVE: To assess the clinical efficacy of the saw palmetto fruit extract (SPFE) in the treatment of lower urinary tract symptoms (LUTS) in patients with type â ¢A prostatitis. METHODS: This retrospective study included 54 cases of type â ¢A prostatitis treated in the Outpatient Department of our hospital from January to December 2015. The patients were aged 35.06 ± 5.85 years, with a mean disease course of 3.8 ± 2.1 years, and all received oral medication of SPFE Capsules at the dose of 320 mg qd for 12 weeks. We assessed the therapeutic effects by comparing the NIH-chronic prostatitis symptom indexes (NIH-CPSI), voiding diary, International Prostate Symptom Scores (IPSS), and results of urodynamic examination before and after treatment. RESULTS: Compared with the baseline, both NIH-CPSI and IPSS were significantly decreased after medication (27.61 ± 3.76 vs 18.6 ± 5.34, P <0.01; 20.44 ± 4.51 vs 10.96±4.62, P <0.01), and urodynamic examination and voiding diary showed dramatic post-medication improvement in the average urinary flow rate (ï¼»8.05±1.42ï¼½ vs ï¼»12.05±2.60ï¼½ ml/s, P <0.01 ), maximum urinary flow rate (ï¼»14.22±1.74ï¼½ vs ï¼»21.32±4.51ï¼½ ml/s, P <0.01), residual urine volume (ï¼»46.15±16.57ï¼½ vs ï¼»14.55±10.21ï¼½ ml, P <0.01), maximum urethral closure pressure (ï¼»76.52±3.53ï¼½ vs ï¼»65.32±4.75ï¼½ cm H2O, P <0.01), mean urinary volume (ï¼»124.63±40.55ï¼½ vs ï¼»285.93±58.68ï¼½ ml, P <0.01), urination frequency (16.96±4.17 vs 8.96±2.50, P <0.01), and nocturia frequency (8.94±3.23 vs 3.15±1.90, P <0.01). No apparent adverse reactions were observed in any of the patients. CONCLUSIONS: SPFE Capsules can safely and effectively improve LUTS and thus the quality of life of patients with type â ¢A prostatitis.

OBJECTIVE: To assess the efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia (BPH). METHODS: We conducted a multi-centered open clinical study on 165 BPH patients treated with Saw Palmetto Extract Capsules at a dose of 160 mg qd for 12 weeks. At the baseline and after 6 and 12 weeks of medication, we compared the International Prostate Symptom Scores (IPSS), prostate volume, postvoid residual urine volume, urinary flow rate, quality of life scores (QOL), and adverse events between the two groups of patients. RESULTS: Compared with the baseline, both IPSS and QOL were improved after 6 weeks of medication, and at 12 weeks, significant improvement was found in IPSS, QOL, urinary flow rate, and postvoid residual urine. Mild stomachache occurred in 1 case, which necessitated no treatment. CONCLUSION: Saw Palmetto Extract Capsules were safe and effective for the treatment of BPH.

AIM: To explore the effects and mechanisms of caffeine and coffee on bladder dysfunction in streptozotocin-induced diabetic rats. METHODS: Sprague-Dawley male rats were divided randomly into 4 groups: control, diabetes mellitus (DM), DM with coffee treatment, and DM with caffeine treatment. The diabetic rat was induced by intraperitoneal injection of streptozotocin (60 mg/kg). After 7 weeks of treatment with coffee and caffeine, cystometrogram, contractile responses to electrical field stimulation (EFS) and acetylcholine (ACh), and cyclic AMP (cAMP) concentration of the bladder body and base were measured. RESULTS: The bladder weight, volume threshold for micturition and post-void residual volume (PVR) in the diabetic rats were significantly higher compared to those in the control animals. Coffee or caffeine treatment significantly reduced the bladder weight, bladder capacity and PVR in the diabetic rats. DM caused significant decreases in cAMP concentration of the bladder and coffee and caffeine caused upregulation of cAMP content in the diabetic bladder. In addition, coffee and caffeine tended to normalize the altered detrusor contractile responses to EFS and ACh in the diabetic rats. CONCLUSION: These results indicate that caffeine and coffee may have beneficial effects on bladder dysfunction in the early stage of diabetes by increasing cAMP content in the lower urinary tract, recovering the micturition reflex and improving the detrusor contractility.
