Since September 1992, 63 patients with symptomatic benign prostatic hyperplasia (BPH) have been treated with transurethral microwave thermotherapy (TUMT) using the Prostatron device. The International Prostate Symptom Score (I-PSS) and quality of life (QOL) score were used to evaluate subjective symptoms. The mean I-PSS (total, irritative and obstructive scores) and QOL scores had decreased by 40, 38, 45 and 40%, respectively, at 12 months (p < 0.0001). While the mean peak flow rate had increased by 72% (p < 0.001). The clinical efficacy at 12 months was 42%, using a modification of the response criteria proposed at the 2nd International Consultation on Benign Prostatic Hyperplasia. There were no significant differences in the baseline and treatment parameters between those who responded favorably to TUMT and those who did not. The total thermal dose delivered to the prostate did not predict clinical response. However, there was a positive correlation between I-PSS or QOL at baseline and % reduction at 3, 6 and 12 months, and a negative correlation between peak flow rate at baseline and % increase at 3 and 6 months. There were no major complications associated with TUMT during the follow-up period. In summary, our 1-year clinical results are compatible with previous reports, suggesting that TUMT is a safe, effective and lasting non-surgical treatment for BPH. However, evaluation of efficacy should be based on uniform criteria to facilitate comparisons of different clinical trials. The most suitable patient profiles for TUMT could not be identified by retrospective analysis.

Objective: To study the effects of intravitreal anti-Vascular Endothelial Growth Factor (VEGF) therapy with Avastin for wet Age-Related Macular Degeneration (AMD) on Benign Prostatic Hyperplasia (BPH)-related symptoms. Methods: An exploratory trial was conducted from August 1, 2013 to February 1, 2014, that included 14 male patients previously diagnosed with BPH, who were aged between 59 and 69 years. The trial was performed in Bucharest and involved two medical institutions: the Clinical Hospital of Eye Emergencies and the "Prof. Dr. Theodor Burghele" Hospital. This prospective study utilized both objective and subjective indicators to analyze the link between intravitreal anti-VEGF therapy for wet AMD and BPH. The evaluations consisted of uroflowmetry and International Prostate Symptom Score (I-PSS) assessments. Results: The maximum flow rate (Qmax) improved by an average of 5.05 ml/ sec in 9 patients, whereas the remaining 5 patients showed a slight decrease in Qmax (mean 1.6 ml/ sec). The I-PSS score improved, with an overall decrease of 1.18 points at follow-up compared to the initial score (mean initial score = 2.42; mean follow-up score = 1.24). Conclusion: The analysis revealed that anti-VEGF therapy for wet AMD had a significant positive effect on all BPH-related symptoms; patients reported improved urinary streams and decreased nocturia.
