RESUMO

OBJECTIVE: Often a sick or an anxious person can experience pain or anxiety relief if another person holds his or her hand. In this study, we conducted investigations to determine whether hand-holding during cystoscopy decreases patient anxiety, pain, and dissatisfaction while at the same time increasing patient comfort and tolerance during the procedure. PATIENTS AND METHODS: Eighty-six male patients who underwent flexible cystoscopy between November 2015 and March 2017 were randomized as follows: hand-holding (group I, n = 43) or non-hand-holding (group II, n = 43) during the procedure. Before flexible cystoscopy, lidocaine gel was instilled in the urethra. Patients' anxiety levels were quantified using the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for self-assessment of satisfaction, discomfort, and willingness to undergo repeat cystoscopy. RESULTS: Demographic characteristics, mean age, procedure duration, procedure indications, and preprocedural analyses did not differ significantly between the 2 groups. In group I, the postprocedural mean anxiety level, pain score, heart rate, and systolic blood pressure were significantly lower compared with those in group II (p = 0.009, p = 0.003, p = 0.022, and p = 0.014, respectively). In group I, postprocedural mean satisfaction score were higher, and patients were more likely to undergo a repeat cystoscopy, compared with those in group II (p = 0.001 and p = 0.004, respectively). CONCLUSIONS: Hand-holding during cystoscopy significantly reduced patients' feelings of anxiety, pain, discomfort, and dissatisfaction. Hand-holding served as a simple, inexpensive, and effective adjunct to sedation during cystoscopy.

RESUMO

OBJECTIVES: To investigate the effect of chronic stress on bladder function. We used awake cystometry and investigated the expressions of contractile-associated proteins. METHODS: Sixteen adult female Sprague-Dawley rats, weighing approximately 220 g, were randomly assigned and divided into control (CON, n = 8) and chronic variable stress (CVS, n = 7) groups. The rats of the CVS group spent 6 weeks under the CVS protocol. After 6 weeks, continuous filling cystometry was performed on conscious animals. The basal pressure, maximal pressure, micturition duration, threshold pressure, micturition interval and micturition volume were measured in each rat. After measuring cystometric parameters, the rat was sacrificed. Western blotting of the entire urinary bladder was performed for detecting the changes in contractile-associated protein expression. RESULTS: Compared to the control group, basal pressure and threshold pressure were significantly higher (P < 0.05) while micturition duration, micturition interval and micturition volume were significantly lower in the CVS group (P < 0.05). In the western blot study, neuronal nitric oxide synthase (nNOS) expression was weaker and RhoA/Rho-kinase alpha were stronger in the CVS group than those in the CON group. CONCLUSIONS: These results suggest that chronic variable stress induces changes in bladder function lead to bladder hyperactivity and possibly related to the changes in RhoA/Rho-kinase and nNOS.

RESUMO

OBJECTIVE: To determine whether listening to music during transrectal ultrasound (TRUS)-guided 12-core needle prostate biopsy decreases anxiety, pain and dissatisfaction among patients and results in a more comfortable and better tolerated procedure. PATIENTS AND METHODS: 76 male patients who underwent TRUS-guided prostate biopsy between March 2013 and June 2014 were randomized into the following groups: no music (group I, n = 38) or classical music (group II, n = 38) during the procedure. Before TRUS-guided prostate biopsy, lidocaine gel was instilled into the rectum. Patient anxiety levels were quantified using the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for self-assessment of satisfaction, discomfort and willingness among patients to have a repeat TRUS-guided prostate biopsy. RESULTS: Demographic characteristics, mean age, procedure duration and procedure indications did not differ statistically between the two groups. The mean anxiety level and mean pain score of group II were significantly lower than those of group I (p = 0.001 and p = 0.003, respectively). Group II also had a significantly higher mean satisfaction score than group I (p = 0.007). Before the procedure, heart rate and systolic blood pressure were similar in groups I and II; however, after the procedure, levels were lower in group II than in group I (heart rate, p = 0.014; systolic blood pressure, p = 0.011). CONCLUSION: Listening to music during TRUS-guided prostate biopsy significantly reduced patients' feelings of pain, discomfort and dissatisfaction. Music can serve as a simple, inexpensive and effective adjunct to sedation during TRUS-guided prostate biopsy. We recommend playing music during TRUS-guided prostate biopsy.

RESUMO

PURPOSE: Thanks to advancements in surgical techniques and instruments, many surgical modalities have been developed to replace transurethral resection of the prostate (TURP). However, TURP remains the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH). We conducted a meta-analysis on the efficacy and safety of minimally invasive surgical therapies for BPH compared with TURP. METHODS: This meta-analysis used a Medline search assessing the period from 1997 to 2011. A total of 784 randomized controlled trials were identified in an electronic search. Among the 784 articles, 36 randomized controlled trials that provided the highest level of evidence (level 1b) were included in the meta-analysis. We also conducted a quality analysis of selected articles. RESULTS: Only 2 articles (5.56%) were assessed as having a low risk of bias by use of the Cochrane collaboration risk of bias tool. On the other hand, by use of the Jadad scale, there were 26 high-quality articles (72.22%). Furthermore, 28 articles (77.78%) were assessed as high-quality articles by use of the van Tulder scale. Holmium laser enucleation of the prostate (HoLEP) showed the highest reduction of the International Prostate Symptom Score compared with TURP (P<0.0001). Bipolar TURP, bipolar transurethral vaporization of the prostate, HoLEP, and open prostatectomy showed superior outcome in postvoid residual urine volume and maximum flow rate. The intraoperative complications of the minimally invasive surgeries had no statistically significant inferior outcomes compared with TURP. Also, there were no statistically significant differences in any of the modalities compared with TURP. CONCLUSIONS: The selection of an appropriate surgical modality for BPH should be assessed by fully understanding each patient's clinical conditions.

RESUMO

PURPOSE: Patients with bladder pain syndrome/interstitial cystitis (BPS/IC) can have pain as a main symptom and overactive bladder (OAB) symptoms that are directly or indirectly related to a major mechanism that causes pain. The primary purpose of this study is firstly to identify the prevalence rate of OAB symptoms in patients with BPS/IC, secondly to identify changes in OAB symptoms after low-dose triple therapy, and thirdly to build a theoretical foundation to improve quality of life for patients. METHODS: Patients who met the inclusion criteria of BPS/IC through basic tests including the O'Leary-Sant symptom index, overactive bladder symptom score (OABSS), and visual analog scale (VAS) were identified. Treatment-based changes in OAB symptoms were identified using the IC Symptom Index and IC Problem Index (ICSI/ICPI), OABSS, and VAS before, and 4 and 12 weeks after low-dose triple therapy. RESULTS: The patients consisted of 3 men and 20 women, and their mean age was 61.9 years (41.0-83.2 years). Comparing values before treatment, and 4 and 12 weeks after treatment (baseline vs. 4 weeks to baseline vs. 12 weeks), the rates of improvement were as follows: ICSI, 44.2% to 63.7%; ICPI, 46.9% to 59.4%; OABSS, 34.3% to 58.2%; and VAS, 53.6% to 75.0%, which showed statistically significant differences (P<0.05). However, comparing values at 4 and 12 weeks after treatment (4 weeks vs. 12 weeks), the ICSI and VAS showed a statistically significant decrease (P<0.05). The ICPI and OABSS showed slight improvement, but no statistically significant differences (P>0.05). CONCLUSIONS: Low-dose triple therapy in BPS/IC results in a clear decrease in OAB symptoms in the first 4 weeks after treatment, and additional treatment for 8 weeks had a partial effect with varied statistical significances depending on the questionnaires.

RESUMO

Managing persistent and symptomatic urachal anomalies requires wide surgical excision of all anomalous tissue with a cuff of bladder tissue via the open approach. We report 7 cases with complete laparoscopic removal of symptomatic urachal remnants with or without a cuff of bladder tissue. We expected that this technique would be less invasive and have lower morbidity. We report on the feasibility of this approach, including efficacy and outcomes. Eight patients with a mean age of 36.5 years who had symptomatic urachal diseases underwent laparoscopic excision between July 2004 and July 2012. With the use of four ports, the urachal remnant was dissected transperitoneally and then removed via the umbilicus port. The clinical results of laparoscopic urachal remnant excision as a minimally invasive surgery, the perioperative records, and pathologic results were evaluated. There were no intraoperative or postoperative complications. Mean surgery time was 2.7 hours. Mean hospital stay was 14.6 days. The patients with bladder cuff resection had a long admission and Foley catheterization period (mean, 14.4 and 11 days). Pathological evaluations were 6 cases of infected urachal cysts, 1 case of infected urachal sinus, and 1 case of urachal adenocarcinoma. We found no postoperative complications including any symptom recurrence or voiding difficulty during a mean follow-up of 46.3 months. The perioperative surgical outcomes achieved infection control and symptomatic relief and additionally good cosmesis. Complete laparoscopic removal of symptomatic urachal remnants with or without a cuff of bladder tissue seems to be a safe, effective, and better cosmetic alternative with the advantages of a minimally invasive approach.

RESUMO

Herein, we describe a perineum-based pediculated scrotal flap procedure for urethral reconstruction. A scrotal tubular flap was used as a substitute to correct a proximal penile urethral stricture in case 1. In case 2, a scrotal island patch was performed to treat an iatrogenic penile urethral injury. In both cases, the urethral catheter was removed on postoperative day 14 with simultaneous normal voiding cystourethrography. The excellent axial vascularization of this perineum-based pediculated scrotal flap procedure allows successful urethral reconstruction, regardless of extension, location, and etiology.

RESUMO

Excess production of nitric oxide by activated macrophages via inducible nitric oxide synthase leads to the development of various inflammatory diseases. Heme oxygenase-1 expression via activation of nuclear factor-erythroid 2-related factor 2 inhibits nitric oxide production and inducible nitric oxide synthase expression in activated macrophages. Okanin is one of the most abundant chalcones found in the genus Bidens (Asteraceae) that is used as various folk medications in Korea and China for treating inflammation. Here, we found that okanin (possessing the α-ß unsaturated carbonyl group) induced heme oxygenase-1 expression via nuclear factor-erythroid 2-related factor 2 activation in RAW264.7 macrophages. 3-Penten-2-one, of which structure, as in okanin, possesses the α-ß unsaturated carbonyl group, also induced nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression, while both 2-pentanone (lacking a double bond) and 2-pentene (lacking a carbonyl group) were virtually inactive. In lipopolysaccharide-activated RAW264.7 macrophages, both okanin and 3-penten-2-one inhibited nitric oxide production and inducible nitric oxide synthase expression via heme oxygenase-1 expression. Collectively, our findings suggest that by virtue of its α-ß unsaturated carbonyl functional group, okanin can inhibit nitric oxide production and inducible nitric oxide synthase expression via nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression in lipopolysaccharide-activated macrophages.

RESUMO

PURPOSE: Triple therapy with gabapentin, amitriptyline, and nonsteroidal antiinflammatory drugs is efficacious for chronic bladder pain syndrome/interstitial cystitis (BPS/IC). However, transient, fluctuating, worsening pain or flare-up symptoms may develop during treatment for a variety of reasons. Here, we assessed the validity of our observational experience regarding a short course of oral prednisolone therapy, which might be of value in the management of flare-up symptoms of BPS/IC. METHODS: Between May 2007 and May 2012, 7 women (mean age, 61.5 years; range, 44.8 to 75.4 years) with BPS/IC presenting with transient, fluctuating, worsening pain as a flare-up symptom despite low-dose triple therapy received a 1- to 3-month course of oral prednisolone 10 mg. The outcome measures used were the IC symptom scale (ICSS, O'Leary-Sant Interstitial Cystitis Symptom Index) and a visual analogue scale (VAS), which were completed at baseline and after treatment. RESULTS: There were statistically significant differences in the ICSS and VAS score before and after prednisolone treatment (P<0.05 by Wilcoxon singed-rank test). The pretreatment IC symptom index (ICSI), IC problem index (ICPI), and VAS score were 16.7± 2.2, 13.7±2.3, and 8.3±1.5 (mean±standard deviation [SD]), and the posttreatment scores were 4.9±2.3, 4.3±1.1, and 2.5±0.9 (mean±SD), respectively. The ICSI, ICPI, and VAS scores were improved after prednisolone treatment by 70.7%, 68.6%, and 69.9%, respectively. Low-dose triple therapy with prednisolone caused no significant adverse effects. CONCLUSIONS: In patients with BPS/IC who show transient, fluctuating, worsening pain as flare-up symptoms despite undergoing low-dose triple therapy, a short course of oral prednisolone therapy was sufficiently effective. However, large-scale studies should be performed to verify our findings.

RESUMO

PURPOSE: The glutathione-S-transferase (GST)P1, GSTM1, and GSTT1 genotypes have been associated with an increased risk of prostate, bladder, and lung cancers. The aim of this study was to investigate the association between the GSTP1, GSTM1, and GSTT1 genotypes and the risk of prostate cancer in Korean men. MATERIALS AND METHODS: The study group consisted of 166 patients with histologically confirmed prostate cancer. The control group consisted of 327 healthy, cancer-free individuals. The diagnosis of prostate cancer was made by transrectal ultrasound-guided biopsy. Patients with prostatic adenocarcinoma were divided into organ-confined (≤pT2) and non-organ-confined (≥pT3) subgroups. The histological grades were subdivided according to the Gleason score. The GSTP1, GSTM1, and GSTT1 genotypes were determined by using polymerase chain reaction-based methods. The relationship among GSTP1, GSTM1, and GSTT1 polymorphisms and prostate cancer in a case-control study was investigated. RESULTS: The frequency of the GSTM1 null genotype in the prostate cancer group (54.2%) was higher than in the control group (odds ratio=1.53, 95% confidence interval=1.20-1.96). The comparison of the GSTP1, GSTM1, and GSTT1 genotypes and cancer prognostic factors, such as staging and grading, showed no statistical significance. CONCLUSIONS: An increased risk for prostate cancer may be associated with the GSTM1 null genotype in Korean men, but no association was found with the GSTT1 or GSTP1 genotypes.

RESUMO

OBJECTIVE: We carried out a nationwide epidemiological study to evaluate the prevalence and effect of varicoceles on testicular volume in South Korean adolescents. We also investigated the correlation between varicoceles and body mass index (BMI). METHODS: In this prospective study, physical examinations were carried out to assess the presence and severity of varicoceles in middle school boys from six regions of South Korea. Testicular volume, height and weight of all boys were measured. The prevalence of varicoceles was assessed. The associations between age, testicular volume, BMI, and the presence and severity of varicoceles were examined. RESULTS: A total of 1938 boys with a mean age of 14.1 years (range 13-16 years) were screened. A varicocele was found on the left side in 295 (15.2%) boys and on the right side in 8 (0.4%) boys. Bilateral varicoceles were found in 17 (0.9%) individuals. Of the subjects with a left varicocele, 151 (51.2%), 80 (27.1%) and 64 (25.1%) boys had a grade 1, 2 or 3 varicocele, respectively. The prevalence of varicoceles did not increase with age. The proportion of boys with testicular size discrepancies increased with the severity of the varicocele. After adjusting for age, BMI had a negative correlation with the presence of varicoceles. CONCLUSIONS: The prevalence of varicoceles in South Korean middle school boys is 16.5%. The presence of varicoceles seems to have a negative effect on testicular growth. BMI has a significant inverse relationship with the occurrence of varicoceles.

RESUMO

PURPOSE: The value of total transurethral resection of prostate cancer (TURPC) as an alternative therapy was first recognized by Hans J. Reuter. Thus, we conducted the study of prospectively collected data to verify total TURPC as an alternative therapy forlocalized prostate cancer. METHODS: From January 2008 to July 2011, 14 patients with a mean age of 76.1 years (range, 66 to 89 years) with clinically localized prostate cancer were treated by prostatic resection by the corresponding author with curative intention. RESULTS: The mean duration of TURPC was 51.7 minutes (range, 30 to 120 minutes) and the mean amount of prostatic tissue resected was 21.2 g (range, 5 to 66 g). An intra- and/or postoperative blood transfusion was necessary in 2 cases. Hyponatremia was found in 7 patients. Six months after TURPC, 3 cases of grade 1 and 1 case of grade 2 incontinence were observed. Three patients in the high-risk group did not achieve a prostate specific antigen (PSA) nadir of ≤0.2 ng/mL. PSA recurrence occurred in one case in our series. Newly developed lymph node or distant metastases were not observed during the follow-up period. CONCLUSIONS: According to our results, transurethral resection for prostate cancer can be performed with reasonable oncological results. The PSA nadir levels, and rates of biochemical failure and postoperative complications, including incontinence, were comparable with the published results for other procedures. TURPC is also inexpensive and non-invasive, and requires short hospitalization and a short surgical time without vesicourethral anastomosis.

RESUMO

The most common cause of vesicovaginal fistulasis injury to the bladder at the time of surgery. The operation most frequently responsible for vesicovaginal fistula formation is hysterectomy. The first successful transvaginal approach to vesicovaginal fistula repair was reported by Sims in 1838. Although many surgical procedures exist, there is no best approach for all patients with vesicovaginal fistula. However, it is an essential surgical principle that the fistulous tract and scar should be excised completely. Here we report our technique using a transurethral pointed electrode for the treatment of multiple, small vesicovaginal fistulas and its outcome.

RESUMO

PURPOSE: Ketamine may decrease core-to-peripheral redistribution of heat through direct central sympathetic stimulation and inhibition of norepinephrine uptake into postganglionic sympathetic nerve endings. The purpose of this study was to evaluate the efficacy of epidural ketamine in preventing shivering during transurethral resection of the prostate (TURP) under epidural anesthesia. MATERIALS AND METHODS: Ninety-three male patients scheduled for TURP under epidural anesthesia were enrolled in this study. Patients were randomized into one of three groups. Group 1 consisted of 31 patients who received epidural 0.75% ropivacaine, group 2 consisted of 32 patients who received epidural ketamine (0.2 mg/kg) in addition to 0.75% ropivacaine, and group 3 consisted of 30 patients who received epidural ketamine (0.4 mg/kg) in addition to 0.75% ropivacaine. Shivering and side effects such as hypotension, bradycardia, nausea, and hallucination were recorded during the anesthesia and for 2 hours while in the postanesthetic recovery room. RESULTS: Shivering was statistically more frequent in group 1 than in the other groups. The incidence of sedation was significantly higher in group 3 than in the other groups. The incidences of side effects such as hypotension, bradycardia, and nausea were significantly higher in group 1 than in the other groups. CONCLUSIONS: In this study, epidural ketamine 0.2 mg/kg and 0.4 mg/kg was shown to have a lower incidence of shivering and other side effects except sedation. In patients who undergo TURP under epidural anesthesia, the prophylactic use of low-dose epidural ketamine would be helpful in preventing any adverse effects, including shivering.

RESUMO

Beyond its vasodilator role, vascular nitric oxide (NO), which is synthesized by endothelial NO synthase (eNOS) via its activation, has been shown to play a number of other beneficial roles in the vascular system; it inhibits proliferation of vascular smooth muscle cells, prevents platelet aggregation, and regulates endothelial apoptosis. Such beneficial roles have been shown to be implicated in the regulation of endothelial functions. A loss of NO bioavailability that may result either from decreased eNOS expression and activity or from increased NO degradation is associated with endothelial dysfunction, a key factor in the development of vascular diseases. Heme oxygenase-1 (HO-1), an inducible enzyme, catalyzes the oxidative degradation of heme to free iron, carbon monoxide, and biliverdin, the latter being subsequently converted into bilirubin. In the vascular system, HO-1 and heme degradation products perform important physiological functions, which are ultimately linked to the protection of vascular cells. Studies have shown that HO-1 and heme degradation products exert vasodilatory, antioxidant, anti-inflammatory, antiproliferative and anti-apoptotic effects on vascular cells. Interestingly, these effects of HO-1 and its by-products are similar, at least in part, to those of eNOS-derived NO; this similarity may prompt investigators to study a possible relationship between eNOS-derived NO and HO-1 pathways. Many studies have been reported, and accumulating evidence suggests that HO-1 and heme degradation products can improve vascular function, at least in part, by compensating for the loss of NO bioavailability. This paper will provide the possible pathway explaining how HO-1 and heme degradation products can preserve vascular NO.

RESUMO

PURPOSE: Curcumin (Cur) has been reported to induce apoptosis in human renal carcinoma Caki cells. Dimethoxycurcumin (DMC), one of several synthetic Cur analogues, has been reported to have increased metabolic stability over Cur. We determined whether DMC, like Cur, induces apoptosis in Caki cells and also compared the apoptosis-inducing activity of DMC with that of Cur. MATERIALS AND METHODS: Caki cells were treated with DMC possessing four methoxy groups, Cur possessing two methoxy groups, or bis-demethoxycurcumin (BMC), which lacks a methoxy group. Cell viability was measured by using a methyltetrazolium assay. Flow cytometry and the caspase-3 activity assay were used to detect apoptosis. The release of cytochrome-c (Cyt c) was detected by Western blot analysis. The production of reactive oxygen species (ROS) was measured by flow cytometry. RESULTS: DMC, Cur, and BMC reduced cell viability and induced apoptosis, but the potency varied; DMC was the most potent compound, followed by Cur and BMC. ROS production, Cyt c release, and caspase-3 activity were increased, again in the order DMC>Cur>BMC. N-Acetylcysteine, a potent antioxidant, inhibited ROS production, Cyt c release, caspase-3 activation, and apoptosis induction in DMC-treated cells. CONCLUSIONS: These results indicate that DMC, like the original form of Cur, may induce apoptosis in human renal carcinoma Caki cells through the production of ROS, the release of mitochondrial Cyt c, and the subsequent activation of caspase-3. In addition, DMC is more potent than Cur in the ability to induce apoptosis.

RESUMO

PURPOSE: Bladder pain syndrome is a chronic disease that manifests as bladder pain, frequency, nocturia, and urgency. Gabapentin, amitriptyline, and nonsteroidal anti-inflammatory drugs are efficacious treatments for bladder pain syndrome. Here, we assessed the effect of triple therapy with these drugs in women with bladder pain syndrome. METHODS: Between May 2007 and May 2010, we conducted a prospective nonrandomized study on 74 patients with bladder pain syndrome. Of these patients, 38 (11 men and 27 women; mean age, 55.9 years; range, 25 to 77 years; mean follow-up, 12.6 months) were administered the interstitial cystitis (IC) symptom scales (O'Leary-Sant Symptom Index) and visual analog scale (VAS) 1, 3, and 6 months after treatment to assess the efficacy of triple therapy. RESULTS: The pretreatment O'Leary-Sant IC symptom score was 11.7, and the post-treatment scores were 4.4, 3.8, and 4.0 at 1, 3, and 6 months, respectively; the pretreatment problem index score was 10.5, and the post-treatment scores were 3.7, 2.7, and 2.9 at 1, 3, and 6 months, respectively. The pretreatment VAS score was 6.7, and the post-treatment scores were 1.8, 1.5, and 1.7 at 1, 3, and 6 months, respectively. The O'Leary-Sant IC symptom index and problem index and VAS scores improved considerably 1 month after treatment (P<0.05). However, the results at 1, 3, and 6 months after treatment were not significantly different (P>0.05). CONCLUSIONS: Triple therapy was sufficiently effective in patients with bladder pain syndrome and caused no significant adverse effects. However, large-scale studies should be performed to verify our findings.

RESUMO

Crossed testicular ectopia is an extremely rare congenital disorder in which both testes descend toward the same hemiscrotum. Twenty percent of cases with crossed testicular ectopia are accompanied by urogenital anomalies such as hypospadias, seminal vesicle cysts, renal anomalies associated with obstruction of the ureteropelvic junction, and testicular tumors. In the case reported here, we describe a patient with ganglioneuroblastoma and crossed testicular ectopia.

RESUMO

Cryptococcal infection primarily involves the lung and is hematogenously spread to other organs. Sometimes it might affect the genitourinary tract, and rare cases have been reported involving the prostate without systemic infection. We report a case of granulomatous prostatitis as a result of Cryptococcus neoformans yeast in an immunocompromised patient with alcoholic liver cirrhosis, which was diagnosed by transrectal ultrasound guided biopsy and treated with antifungal medication.

RESUMO

PURPOSE: We evaluated the efficacy and safety of a therapeutic modality involving propiverine combined with doxazosin in patients with overactive bladder (OAB) and benign prostatic obstruction. MATERIALS AND METHODS: Men 50 years or older with OAB symptoms and urodynamically proven bladder outlet obstruction (Abrams-Griffith score greater than 20) were randomized (1:2) into 2 groups, namely group 1-doxazosin controlled release gastrointestinal therapeutic system formulation (4 mg once daily) only and group 2-propiverine hydrochloride (20 mg once daily) plus doxazosin controlled release gastrointestinal therapeutic system formulation for an 8-week treatment regimen. RESULTS: A total of 211 men, including 69 in group 1 and 142 in group 2, were treated and 198 (93.8%) completed the 8 weeks of treatment. Significant improvements were noted in each group after treatment in urinary frequency, maximum flow rate, average micturition volume and International Prostate Symptom Score. Compared with group 1 improvement rates with regard to urinary frequency (23.5% vs 14.3%, p = 0.004), average micturition volume (32.3% vs 19.2%, p = 0.004), and storage (41.3% vs 32.6%, p = 0.029) and urgency (p = 0.019) International Prostate Symptom Score symptoms were more significant in group 2. Post-void residual urine was found to be significantly increased only in group 2 but this was not accompanied by urinary retention. Patient satisfaction rates were found to be significantly higher in group 2 than in group 1 (p = 0.002). Overall adverse event rates were higher in group 2 (p = 0.002), although discontinuation rates and discontinuation rates due to adverse events were not different between the 2 groups. CONCLUSIONS: This study reveals that combination therapy consisting of alpha1-adrenoceptor antagonists with antimuscarinics represents an effective and relatively safe treatment modality in select patients with OAB coexisting with benign prostatic obstruction.
