Abstract Introduction: To assure that patients with lower urinary tract symptoms (LUTS) benefit from interventions, urologists must practice careful selection of surgical candidates. Currently, 15%-30% of men do not benefit optimally from these invasive and potentially morbid procedures. Success rates following transurethral resection of the prostate (TURP) are higher if bladder outlet obstruction (BOO) is confirmed prior to the procedure by invasive pressure flow studies (PFS). However, PFS may not be performed because of many reasons. We report a study of a non-invasive method of assessing BOO.
Materials and methods: The UroCuff test was compared to invasive… More >

Abstract Giant benign prostatic hyperplasia is a rare pathology of the prostate gland. Here we report the successful removal of the ninth largest prostate ever reported. This 65-year-old patient presented with acute urinary retention secondary to a bulky left prostatic mass identified on pelvic magnetic resonance imaging (MRI). His preoperative prostate-specific antigen (PSA) value was 44 ng/mL; preoperative biopsies were negative for malignancy. Open radical retropubic prostatectomy was performed and the resulting prostatic mass was measured at 13.5 cm x 11.5 cm x 5.2 cm, weighing 708 g including the prostate. The patient tolerated the procedure More >

Abstract In the primary care office the evaluation of prostate related lower urinary tract symptoms (BPH-LUTS) in the male can be confusing. Are the symptoms, in fact, from the prostate or is there another etiology such as the bladder or medical conditions causing or contributing to the problems? If the cause is the prostate, how does the physician choose from the multitude of available treatment options and when is referral appropriate? The prevalence of BPH-LUTS is high and commonly encountered by the primary care physician (PCP). An understanding of the normal prostate is essential to identifying More >

Abstract Introduction: The prostatic urethral Lift (PUL) procedure offers a novel treatment for men with lower urinary tract obstructive symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). Most patients who seek LUTS/BPH treatment choose the intervention that offers the expectations of a significant improvement in quality of life and the least chance of short or long term morbidity. We report the results of a prospective, non-randomized study designed to further characterize the perioperative subject experience with the PUL procedure.
Materials and methods: The PUL procedure employs permanent implants to mechanically pull the prostatic lateral lobes apart. Subjects… More >

Abstract Introduction: We assessed the efficacy of onabotulinumtoxinA (Botox, Allergan Inc., Irvine, CA, USA) in patients with refractory overactive bladder (OAB) after treatment for benign prostatic hyperplasia (BPH).
Materials and methods: This was a two-center, randomized, double-blinded pilot study conducted in patients with OAB secondary to bladder outlet obstruction (BOO), refractory to anticholinergic medication and persistent for greater than 3 months after surgical intervention to relieve obstruction, with an International Prostate Symptom Score (IPSS) >12. Patients were randomized in 1:1 fashion to either 200 units of onabotulinumtoxinA versus placebo. Fifteen patients received onabotulinumtoxinA versus 13 who received… More >

Abstract Introduction: To evaluate a hybrid technique involving GreenLight 120W HPS vapor incision tissue removal in prostate glands > 80 cc.
Materials and methods: Vapor incision technique (VIT) was performed in 25 consecutive men with a prostate > 80 cc by a single surgeon from May 2010 until September 2010. VIT involved adenoma incisions at 5 and 7-o'clock positions followed by 3, 9 and 12 o'clock down to the surgical capsule. Side-fire vaporization along the capsule excised transurethral resection of the prostate (TURP) like tissue strips for later retrieval. Functional evaluations were performed at 1 and 3 months.… More >

Abstract Introduction: To report our preliminary techniques and experience with retroperitoneoscopic single-site renal pedicle lymphatic disconnection (RPSS-RPLD) in five patients with serious filarial chyluria.
Materials and methods: Between May 2010 and July 2011, five patients with serious filarial chyluria underwent RPSS-RPLD. In each patient, a 3 cm single incision was made between the 12th subcostal margin and posterior axillary line, and a homemade single multichannel port using a surgical glove and three conventional trocars was placed into the retroperitoneal space. The lymphatic disconnection procedure was similar to that of traditional open surgery.
Results: All operations were successfully completed without More >

Abstract Introduction: Urinary prostate-specific antigen (uPSA) can be used as an additional parameter of benign prostatic hyperplasia (BPH) progression.
Materials and methods: From January 2001 to December 2011, uPSA was determined in 265 patients with benign prostate. Based on total prostate volume (TPV), the patients with benign prostate were divided into two groups: TPV < 31 mL and TPV ≥ 31 mL. Additionally, three groups were formed according to MTOPS study criteria: non-progressive BPH group (TPV < 31 mL, PSA < 1.6 ng/mL, age < 62 yrs), intermediate group (one or two parameters {TPV, PSA, age} increased), and… More >

Abstract Introduction: Benign prostatic hyperplasia (BPH) is a more common form of lower urinary tract symptoms (LUTS). BPH is due to the excessive growth of both stromal and epithelial cells of the prostate. Fifty percent of men over the age of 50 will have this disease, along with the probability that 90% of men at the age of 80 will have an enlarged prostate. The prevalence of vitamin D deficiency in the male urological population may represent a connection between BPH and vitamin D.
Material and methods: This review is geared to provide the most relevant data on… More >

Abstract Introduction: Inflammation plays a key role in the development of benign prostatic hyperplasia. Prostaglandin E2 (PGE2) is an important inflammation factor found in enlarged prostatic tissue that can be the main cause of inflammatory pain. The aim of this study was to investigate whether epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.
Materials and methods: The study included 60 patients who underwent open prostatectomy. All patients were randomly allocated to one of two study groups. The first group received general anesthesia and the second group a combination of general and epidural anesthesia.… More >
