RESUMO
BACKGROUND: We evaluated the association of prostate volume (PV) with the efficacy and safety of transurethral enucleation with bipolar energy (TUEB) for treatment of benign prostatic hyperplasia (BPH). METHODS: We retrospectively evaluated data from 180 patients with symptomatic BPH who underwent TUEB between 2008 and 2015. Efficacy was assessed by perioperative changes in international prostate symptom score (IPSS), Quality of Life Score (QOLS), maximum flow rate on uroflowmetry (Qmax), and serum prostate-specific antigen level (PSA), which were recorded at 3 months postoperatively. Safety was assessed by perioperative incidence of adverse events (AEs). AEs were recorded up to 2 years after surgery. Patients were divided into two groups based on PV as the standard group (SG; PV < 80 mL) and large group (LG; PV ≥ 80 mL). RESULTS: A total of 132 (73%) patients were grouped as the SG, and 48 (27%) were grouped as the LG. No significant differences between the groups were observed in the preoperative variables age, IPSS, and QOLS. However, the LG had a significantly larger PV and higher serum PSA levels. Analysis of surgical outcomes revealed that postoperative changes in IPSS, QOLS, Qmax, serum PSA, serum sodium, and hemoglobin levels did not differ significantly between groups. However, LG had a significantly longer operative time and heavier specimen weight. The rates of early complications, including hyponatremia and blood transfusion, and late complications after surgery did not differ between the groups. CONCLUSION: The present findings suggest that TUEB is safe and effective for treatment of BPH, regardless of PV.

The present study investigated whether combined ingestion of green tea catechins (GTC) and monoglucosyl hesperidin (GHES) influences the pharmacokinetic parameters of polyphenols and serum triglycerides (TG). We conducted 2 randomized, controlled trials. Study 1: 8 healthy male subjects participated in a crossover study in which they ingested a test beverage containing GHES (0, 84, 168, or 336 mg GHES) with GTC, or 336 mg GHES without GTC. After ingestion, the pharmacokinetic changes in plasma hesperetin (HEP) and catechins were measured. Study 2: 36 healthy male and female subjects (mean age, 53 ± 2 years; mean BMI, 25.2 ± 0.5 kg m-2) were recruited for a double-blind, placebo-controlled study in which they ingested a test beverage containing 165 mg GHES with 387 mg GTC or a placebo beverage daily for 4 weeks. Fasting serum TG and other lipids and glucose metabolites were analyzed. Study 1 showed that the pharmacokinetics of HEP did not differ significantly between the 336 mg GHES without GTC treatment and the 168 mg GHES with GTC treatment. Study 2 showed that continuous ingestion of 165 mg GHES and 387 mg GTC for 4 weeks significantly decreased fasting serum TG levels compared with baseline values (change in TG, -30 ± 13 mg dl-1, P = 0.040) in the intention-to-treat analysis. In conclusion, our findings suggest that GTC affects the oral bioavailability of GHES, and combined ingestion of low doses of GHES with GTC effectively improves fasting TG levels.
