PURPOSE: To evaluate the incidence of and factors associated with intraoperative floppy iris syndrome (IFIS) in patients undergoing cataract phacoemulsification. METHODS: In total, 319 eyes of 319 patients who underwent phacoemulsification with implantation of an intraocular lens (IOL) into the posterior chamber were included in this study. Direct injection of epinephrine into the anterior chamber was performed in all cases. The following patient information was collected: gender, age, axial length of the eye, presence of pseudoexfoliation syndrome, glaucoma, diabetes mellitus, hypertension, current use of medications including alpha1 adrenergic receptor antagonists (alpha1-ARAs), finasteride, and benzodiazepines, duration of intake of alpha1-ARAs and finasteride, and duration of the surgery...

PURPOSE: To investigate the effects of combined treatment of tadalafil (a phosphodiesterase-5 inhibitor) and tamsulosin (an α1 -adrenoceptor antagonist) on bladder dysfunction in a rat model of bladder outlet obstruction (BOO). METHODS: Cystometry was performed in conscious female BOO rats 6 weeks after partially ligation of the urethra. Either tadalafil (0.03, 0.1 and 0.3 mg/kg) or tamsulosin (0.001, 0.003 and 0.01 mg/kg) was cumulatively applied intravenously at 30-min intervals to examine changes in cystometric parameters and blood pressures...

OBJECTIVE: To verify the efficacy and safety of tamsulosin 0.4 mg and tamsulosin 0.2 mg compared with those of placebo in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). METHODS: A total of 494 patients from multiple centers participated in this double-blind, randomized, phase 3 trial. The eligible patients were randomly assigned to the tamsulosin 0.4 mg group, tamsulosin 0.2 mg group, or placebo group...

INTRODUCTION AND OBJECTIVES: Percutaneous nephrolithotomy remains a challenging procedure primarily due to difficulties obtaining access. Indeed, few urologists obtain their own access due to difficulties using a fluoroscopic or ultrasonic based antegrade puncture technique. Herein we report the first experience using holmium laser energy to obtain access in a retrograde fashion. METHODS: After a pretreatment week of tamsulosin 0.4 mg/day (one center only) and following a documented sterile urine, a total of ten patients underwent retrograde holmium laser-assisted endoscopic-guided nephrostomy access in a prone split leg position...

A 68-year-old man with chronic myelogenous leukemia presents for evaluation of 2 months of dyspnea with exertion. He denies cough, fever, chest pain, weight gain, orthopnea, and edema. Since diagnosis of chronic myelogenous leukemia 5 years ago, he has been treated with dasatinib, with recent BCR-ABL1 assay showing no detectable disease in the peripheral blood. Medical history also includes hyperlipidemia, prostate enlargement, and hypothyroidism, but no prior heart or lung disease. Born in the Middle East, he immigrated to the United States 30 years ago and is working as a physician...

PURPOSE: To evaluate the add-on efficacy of a cyclooxygenase (COX)-2 inhibitor on the chronological changes in urinary function in patients who underwent low-dose-rate prostate brachytherapy. METHODS AND MATERIALS: A total of 310 patients with prostate cancer who underwent low-dose-rate-brachytherapy were enrolled. Patients were randomized and allocated to the monotherapy group (tamsulosin alone: 0.2 mg/d) and the combination group (tamsulosin 0.2 mg/d plus celecoxib: 200 mg/d)...

BACKGROUND: High urinary infection (UTI) rate (12%) for our rectal surgery prompted practice change to early catheter removal (postoperative day 2) and prophylactic tamsulosin. Here we report urinary retention (UR) and UTI after this change. METHODS: Retrospective cohort study in male patients 50+ years undergoing elective colorectal surgery from July 2015 to July 2017. Multivariate regression was used to determine risk factors for urinary retention. RESULTS: 157 patients, 57 without and 100 with tamsulosin had UR 11...

BACKGROUND: To investigate the efficacy of tamsulosin in patients with lower urinary tract symptoms (LUTS) and benign prostatic enlargement (BPE) with intravesical prostatic protrusion (IPP). Ultrasound measurement of the IPP has been previously described as an effective instrument for the evaluation of benign prostatic obstruction (BPO) and could help in clarifying the role of alpha-blockers in patients with (BPE). METHODS: Patients with BPE and LUTS were enrolled in this observational study...

In this study, using the melt-adsorption method, we developed sustained-release microparticles containing the potent drug, tamsulosin HCl, for use as orally disintegrating tablets. A high-speed kneading granulator was used, enabling temperature modulation and uniform material distribution. A lipid and ethylcellulose suspension (Surelease®) was applied to retard drug release, and magnesium aluminometasilicate (Neusilin®) was used as adsorbent. Among various lipid candidates for melt-adsorption, beeswax and glyceryl behenate were selected due to their high mechanical strength...

Introduction: Alpha blockers are widely used in the treatment of primary bladder neck obstruction; however, evidence for objective urodynamic efficacy is scarce. We studied the effect of the uroselective α1-blocker tamsulosin on urodynamic parameters in male patients with type I primary bladder neck obstruction. Methods: A single center prospective observational study was carried out from July 2013 to February 2015. Male patients (18-50 years) with type 1 primary bladder neck obstruction were recruited...

Alpha blockers (AB) are the main group of drugs used for medical expulsive therapy (MET) in patients with ureteral stones. However, there is no consensus on the relative efficacy and safety of individual AB in MET. Areas covered: The present work is a network meta-analysis of randomized controlled trials comparing AB with either placebo or standard of care in patients with ureteral stones. Electronic databases of Medline, Cochrane CENTRAL and Google Scholar were searched for eligible clinical studies. Inverse variance heterogeneity model was used for mixed treatment comparisons...

BACKGROUND: Urolithiasis is a common condition in the U.S. Patients frequently present to the emergency department (ED) for care, including analgesia and treatments to facilitate stone passage. OBJECTIVE: With the new evidence concerning the evaluation and treatment of urolithiasis, this review summarizes current literature regarding the ED management of urolithiasis. DISCUSSION: Urolithiasis occurs primarily through supersaturation of urine and commonly presents with flank pain, hematuria, and nausea/vomiting...

PURPOSE: Clinicians use tamsulosin, an α1-adrenoceptor antagonist, to manage symptomatic benign prostatic hyperplasia (BPH). Because α1-adrenoceptors are also present in the brain, the potential exists for adverse effects on cognitive functions. We explored the association between tamsulosin use and dementia risk. METHODS: We used Medicare data (2006-2012) to conduct a cohort study among patients aged ≥65 years and diagnosed with BPH. Men taking tamsulosin (n = 253 136) were matched at a 1:1 ratio using propensity-scores to each of 6 comparison cohorts: patients who used no BPH-medication (n = 180 926), and patients who used the following alternative-BPH-medications: doxazosin (n = 28 581), terazosin (n = 23 858), alfuzosin (n = 17 934), dutasteride (n = 34 027), and finasteride (n = 38 767)...

Objective: To investigate the potential role of alpha1-adrenoceptor (α1-AR) in the pathogenesis of hepatorenal syndrome. Methods: Hepatorenal syndrome was induced in male rats by intraperitoneal injection of D-galactosamine and orally treatment with α1-AR antagonist tamsulosin. Hyperresponsiveness of the renal artery contraction was evaluated by the laser-Doppler flowmetry and multimyograph system, while renal blood flow (cortical and medullary perfusion) was simultaneously measured...

A 54-year-old man presents to the emergency department with acute onset left flank pain that radiates to the groin. A computed tomography scan of the abdomen/pelvis without contrast reveals a 7-mm distal ureteral stone. He is deemed appropriate for outpatient management. In addition to pain medications, should you prescribe tamsulosin?
