Phosphodiesterase type 5 inhibitors usage and prostate cancer: a match-paired analysis.

Background: To treat erectile dysfunction (ED), phosphodiesterase type 5 inhibitors (PDE5i) are commonly used. However, to date, only a few studies exist evaluate a possible effect on the incidence of prostate cancer. One such study completed by the authors' institution suggested men who use PDE5i for ED may have a lower incidence of prostate cancer.

Five year results of the prospective randomized controlled prostatic urethral L.I.F.T. study.

Introduction: To report the five year results of a prospective, multi-center, randomized, blinded sham control trial of the Prostatic Urethral Lift (PUL) in men with bothersome lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

Materials And Methods: At 19 centers in North America and Australia, 206 subjects ≥ 50 years old with International Prostate Symptom Score (IPSS ) > 12, peak flow rate (Qmax) ≤ 12 mL/s, and prostate volume 30 cc-80 cc were randomized 2:1 to the PUL procedure or blinded sham control. In PUL permanent UroLift implants are placed to hold open the lateral lobes of the prostate to reduce urinary obstruction.

Urinary Catheterization: a Paradigm Shift in Difficult Urinary Catheterization.

Background: The urinary catheter is an ancient device for urinary drainage in patients. Placement of a urethral catheter is a common medical procedure that may have led to morbidity and mortality. Urethral catheterization is commonly performed by a nurse.

Three year results of the prostatic urethral L.I.F.T. study.

Introduction: To report the three year results of a multi-center, randomized, patient and outcome assessor blinded trial of the Prostatic Urethral Lift (PUL) in men with bothersome lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

Materials And Methods: At 19 centers in North America and Australia, 206 subjects = 50 years old with International Prostate Symptom Score (IPSS) ≥ 13, peak flow rate (Qmax) ≤ 12 mL/s, and prostate volume between 30 cc-80 cc were randomized 2:1 to the PUL procedure or sham control. PUL involved placing permanent UroLift implants into the lateral lobes of the prostate to enlarge the urethral lumen.

Durability of the Prostatic Urethral Lift: 2-Year Results of the L.I.F.T. Study.

Introduction: For a therapy to become an important part of a provider armamentarium it must be safer or better than existing therapies and be durable. The prostatic urethral lift offers rapid improvement in lower urinary tract symptoms associated with benign prostatic hyperplasia with minimal side effects. We report 2-year results of a multicenter, randomized, blinded trial of the prostatic urethral lift.

The prostatic urethral lift for the treatment of lower urinary tract symptoms associated with prostate enlargement due to benign prostatic hyperplasia: the L.I.F.T. Study.

Purpose: We report the first multicenter randomized blinded trial of the prostatic urethral lift for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia.

Materials And Methods: Men at least 50 years old with AUASI (American Urological Association Symptom Index) 13 or greater, a maximum flow rate 12 ml per second or less and a prostate 30 to 80 cc were randomized 2:1 between prostatic urethral lift and sham. In the prostatic urethral lift group small permanent implants are placed within the prostate to retract encroaching lobes and open the prostatic urethra.

Current trends in the management of difficult urinary catheterizations.

Routine urinary catheter placement may cause trauma and poses a risk of infection. Male catheterization, in particular, can be difficult, especially in patients with enlarged prostate glands or other potentially obstructive conditions in the lower urinary tract. Solutions to problematic urinary catheterization are not well known and when difficult catheterization occurs, the risk of failed catheterization and concomitant complications increase.

Incidence rate of prostate cancer in men treated for erectile dysfunction with phosphodiesterase type 5 inhibitors: retrospective analysis.

The purpose of this study was to determine the incidence rate of prostate cancer among men with erectile dysfunction (ED) treated with phosphodiesterase type 5 inhibitors (PDE-5i) over a 7-year period vs. men with ED of the same age and with similar risk factors who were not treated with PDE-5i. In a retrospective review of electronic medical records and billing databases between the years 2000 and 2006, men with ED between the ages of 50 and 69 years and no history of prostate cancer prior to 2000 were identified.

Anti-caveolin-1 antibodies as anti-prostate cancer therapeutics.

Caveolae are critical cell surface structures important in coordinated cell signaling and endocytosis. One of the major proteins of caveolae is caveolin 1 (Cav-1). Cellular levels of Cav-1 are associated with cancer progression.

Caffeine ingestion and lower urinary tract symptoms in healthy volunteers.

Aims: To assess lower urinary tract symptoms (LUTS) after caffeine ingestion in healthy volunteers.

Materials And Methods: We conducted a randomized, double-blind, placebo-controlled trial utilizing healthy adult volunteers without urinary tract disease. Caffeine dosage was based on patient weight (equivalent to a 70 kg person taking 200 mg of caffeine twice a day).
