Adenoma of the prostate

Purpose: We report our experience with 100 patients who underwent an innovative prostate enucleation technique that spares the complete urethral-plate from the veru montanum to the bladder neck using a low-energy thulium laser emission. The aim of our study was to evaluate the short-term effects of this procedure on ejaculation preservation and urinary obstruction. Materials and Methods: The International Prostate Symptom Index (IPSS), quality of life (QoL), and Male Sexual Health Questionnaire Ejaculatory Dysfunction (MSHQ-EJD) Short Form were used as validated instruments to quantify ejaculatory dysfunction before and 6 months after the surgery...

CONTEXT: Surgical management of lower urinary tract symptoms (LUTS)/benign prostatic obstruction (BPO) aims at ablating prostate adenoma by resection, enucleation, or vaporisation. Apart from established ablation modes according to the European Association of Urology guidelines, various technologies have emerged as safe/effective alternatives but remain under investigation. OBJECTIVE: To explore short-term benefits/harms of emerging technologies for surgical management of LUTS/BPO...

Benign prostatic hyperplasia (BPH) is the most common adenoma in old men. Tomatoes are a rich source of bioactive compounds that, as well as selenium (Se), possess antioxidant and antiproliferative activity. The aim was to evaluate the therapeutic effect of Se in combination with a tomato extract in aged rats with BPH. Aged male Wistar rats were divided in the following groups (n = 10 rats/group): Control (C), BPH, BPH + Finasteride (BPH + F), BPH + Tomato Lipidic Extract (BPH + E), BPH + Selenium (BPH + S) and BPH plus E plus S (BPH + E + S)...

Hypercalcemia of malignancy is commonly associated with several malignancies, but its existence in prostate cancer is an uncommon finding. The concurrent existence of a parathyroid adenoma and a history of hypercalcemia over several decades further adds to the enigma. Our case is of an 82-year-old man with a history of prostate cancer who presented to the endocrinology clinic with hypercalcemia. His PET-CT showed osteolytic metastasis to the T10 vertebrae which were presumed to be the cause of his high serum calcium...

OBJECTIVE: To compare the outcome and morbidity of bipolar transurethral enucleation of the prostate (B-TUEP) and thulium laser enucleation of the prostate (ThuLEP) with those of holmium laser enucleation of the prostate (HoLEP) in the treatment of large symptomatic benign prostatic obstruction (BPO) through a non-inferiority randomized controlled trial (NCT03916536). PATIENTS AND METHODS: A total of 155 patients were recruited from a single centre between February 2019 and August 2020...

BACKGROUND: Sulfur microbial diet (SMD), related to the enrichment of sulfur-metabolizing gut bacteria, has been confirmed to be linked to an elevated risk of early-onset colorectal adenoma in young females. However, it remains unclear whether SMD is associated with the risk of colorectal adenoma in older people, who are at greater risk for colorectal cancer. METHODS: All data on participants in this study were retrieved from the intervention arm of the Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening test...

BACKGROUND: Bleeding and bleeding-related complications remain common after bipolar transurethral resection of the prostate (TURP) for benign prostatic hyperplasia. This may possibly lead to prolonged postoperative irrigation, catheterization, and hospital stay. The objective of this trial was to evaluate the effect of high-dose tranexamic acid (TXA) on perioperative blood loss in patients treated with bipolar TURP for prostate sizes between 30 and 80 g. METHODS: We conducted a single-center, prospective, double-blind, randomized controlled trial...

BACKGROUND: Highly supported microRNAs (miRNAs) are key players in cancer development. Each of these miRNAs may act as an oncomir, a tumor-suppressor, or both in various cancers. Mir-151a-5p is believed to be one of these miRNAs with diverse roles. We have conducted this systematic review to clarify the role of mir-151a-5p in formation of various cancers. METHODS AND MATERIALS: We searched for existing articles in PubMed, Web of Science, Cochrane, Scopus, and RNAcentral databases up to November 2022...

OBJECTIVE: To compare the perioperative outcomes of transvesical single-port robotic simple prostatectomy (SP-RASP) and holmium laser enucleation of the prostate (HoLEP). MATERIALS AND METHODS: A retrospective review was performed of patients undergoing SP-RASP and HoLEP from 2019 to 2022 with preoperative prostatic volume (PPV) >80 cm3 . Percent of prostate adenoma removed (%PAR) was estimated by specimen weight normalized by PPV. Univariate analysis was performed using chi-square, Fisher exact, and Wilcoxon rank-sum tests...

Perfluorinated compounds (PFCs) are man-made chemicals used in the manufacture of many products with water and dirt repellent properties. Many diseases have been proved to be related to the exposure of PFCs, including breast fibroadenoma, hepatocellular carcinoma, breast cancer and leydig cell adenoma. However, whether the PFCs promote the progression of prostate cancer remains unclear. In this work, through comprehensive bioinformatics analysis, we discovered the correlation between the prostate cancer and five PFCs using Comparative Toxicogenomics Database (CTD), Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases...

OBJECTIVE: Prostate-specific membrane antigen (PSMA) is a cell membrane protein expressed by prostate tissues. It is not prostate specific and is also expressed by some non-prostatic solid neoplasms. Our study aimed to investigate the potential role of PSMA in salivary gland tumors. METHODS: The present study was designed to retrospectively analyze our cases that presented with salivary gland tumors. The files of 105 patients were reviewed and their paraffin embedded blocks were retrieved from the pathology department...

SIGNIFICANCE: Mueller-matrix polarimetry is a powerful method allowing for the visualization of malformations in biological tissues and quantitative evaluation of alterations associated with the progression of various diseases. This approach, in fact, is limited in observation of spatial localization and scale-selective changes in the poly-crystalline compound of tissue samples. AIM: We aimed to improve the Mueller-matrix polarimetry approach by implementing the wavelet decomposition accompanied with the polarization-singular processing for express differential diagnosis of local changes in the poly-crystalline structure of tissue samples with various pathology...

BACKGROUND: Most Colorectal cancers arise from adenomas, and though insulinemic and inflammatory dietary patterns have been associated with colorectal cancer risk, these dietary patterns have not been studied in relation to adenoma risk. METHODS: Using data from 21,192 participants in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer screening cohort, we calculated the Empirical Dietary Index for Hyperinsulinemia (EDIH), Empirical Dietary Inflammatory Pattern (EDIP) and overall dietary quality measured via the Healthy Eating Index (HEI-2015), from food frequency questionnaires (FFQ)...

(1) Background: Numerous meta-analyses have shown that a high intake of dietary fiber plays a protective role in preventing the development of various types of cancer. However, previous studies have been limited by focusing on a single type of dietary fiber and variations in outcome measures, which may not be effectively applied to provide dietary guidance for the general population. (2) Object: We summarized the meta-analysis of dietary fiber and cancer, and provided references for residents to prevent cancer...

OBJECTIVES: To compare intra and early postoperative outcomes between pulsed-wave and continuous-wave Thulium Fiber Laser Enucleation of the Prostate (PW-ThuFLEP vs CW-ThuFLEP) for the treatment of benign prostatic hyperplasia (BPH). METHODS: 238 patients with lower urinary tract symptoms (LUTS) due to BPH underwent PW-ThuFLEP (118 patients) vs. CW-ThuFLEP (120 patients). Preoperative prostate volume, adenoma volume, PSA and haemoglobin values were recorded. International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual volume (PVR) and International Index of Erectile Function-5 score (IIEF-5) were assessed...

BACKGROUND: The results regarding the association between insulin-like growth factor binding protein 1 (IGFBP1) expression and cancer risk were controversial. We performed a meta-analysis to provide novel evidence on relationship between IGFBP1 expression and cancer risk. METHODS: PubMed, Embase, Cochrane library and Web of science were searched for relevant cohort and case-control studies exploring the relationship between IGFBP1 expression and cancer risk. Odds ratios (ORs) were pooled in this meta-analysis using random model...

BACKGROUND: Simple open prostatectomy is still the treatment of choice for removing large prostates; however, peri-surgical bleeding accompanied by this technique has always been a challenge for urologist surgeons. Therefore, the present study aimed to investigate the effect of surgicel on reducing bleeding in trans-vesical prostatectomy. MATERIALS AND METHODS: The present double-blinded clinical trial included 54 patients with Benign Prostatic Hyperplasia (BPH), divided into two groups of 27, and underwent trans-vesical prostatectomy...

BACKGROUND: Anatomical endoscopic enucleation of the prostate (AEEP) is recommended for first line surgical treatment of benign prostatic obstruction (BPO) caused by moderate and large prostatic adenoma. However, its role in the retreatment setting after failed previous surgical treatment for BPO remains uncaptured. In this scope, we performed a systematic review and meta-analysis aiming to assess the safety and efficacy of AEEP in the retreatment setting. METHODS: We searched PubMed, Cochrane Library and Embase databases from inception to March 2022 for prospective or retrospective studies involving patients undergoing prostatic enucleation for recurrent or residual BPO after previous standard or minimally invasive surgical treatments for BPO...

Pituitary apoplexy (PA) is a clinical syndrome resulting from sudden hemorrhage and/or infarction of the pituitary gland. Recent reports documented the development of PA secondary to treatment with gonadotropin-releasing hormone (GnRH) agonists for prostate cancer. A 52-year-old woman visited our emergency room with a severe headache, occurred 1 day prior. She underwent breast-conserving surgery for breast cancer 1 month prior. She was currently undergoing radiation and hormone therapy, consisting of leuprorelin...

PURPOSE: To evaluate the safety, efficiency, and size-dependency of the 'Inverted omega En-bloc (Ʊ)' holmium laser enucleation of the prostate (HoLEP) in benign prostate hyperplasia (BPH) with lower urinary tract symptoms. MATERIALS AND METHODS: A retrospective analysis of 716 consecutive patients who underwent HoLEP under the care of a single surgeon from 2014-2021. These patients were treated using the 'Inverted omega En-bloc ' HoLEP technique for BPH. The patients were divided into 3 groups: Group 1 (<40 mL, n=328), Group 2 (40-60 mL, n=221), and Group 3 (≤60 mL, n=167)...
