INTRODUCTION: The objective of our study was to evaluate the efficacy and durability of GreenLight laser prostatectomy for the management of acute urinary retention (AUR) and chronic urinary retention (CUR) and to determine outcomes compared to patients without preoperative urinary retention (UR). METHODS: We conducted a retrospective study of prospectively collected data from individuals who underwent GreenLight laser prostatectomy at our institution from May 2018 to July 2022. Patient demographics and outcome measures were recorded, including indications for the procedure, median urinary volume drained, or median postvoid residual urine volume (PVR) before catheterization or GreenLight laser prostatectomy. CUR was defined as PVR >300 mL in males able to void and initial catheter drainage >1000 mL in males unable to void in the absence of pain. All patients had postoperative followup visits at one, three, six, and 12 months. Our evaluation included the International Prostate Symptom Score (IPSS), quality-of-life (QoL) assessment, maximum urinary flow rate (Qmax), PVR, and catheter-free status. RESULTS: One hundred sixty-eight males who underwent GreenLight laser prostatectomy were included in our study. The UR group consisted of 88 patients (50 AUR and 38 CUR), and the lower urinary tract symptoms (LUTS) group was comprised of 80 individuals. There were no statistically significant differences between the AUR and CUR subgroups regarding demographics. The UR group had a significantly higher age and a significantly higher postoperative catheterization time compared to the LUTS cohort. The CUR subgroup had a significantly higher PVR at one, three, and six months compared to the AUR subgroup, although other outcome measures were similar between the two cohorts. During three- and six-month followup visits, the UR group had a significantly higher PVR than the LUTS cohort. At 12 months postoperative, the LUTS group had a higher catheter-free rate than the UR group (p=0.001). The successful first trial of void (TOV) rate for the UR and LUTS groups were 83% and 80%, respectively. At 12-month followup, the catheter-free rate for the UR and LUTS cohorts was 87.5% and 100%, respectively. CONCLUSIONS: GreenLight laser prostatectomy is an effective and durable treatment for UR, with a high catheter-free rate and comparable outcomes when performed to manage LUTS. [ABSTRACT FROM AUTHOR]

INTRODUCTION: We evaluated the impact of age on perioperative morbidity and clinical outcomes in patients undergoing GreenLight laser prostatectomy for benign prostatic hyperplasia (BPH). METHODS: We conducted a retrospective study of prospectively collected data from individuals who underwent GreenLight laser prostatectomy from May 2018 to July 2022. Patient demographics and outcome measures were recorded, including indications for the procedure and American Society of Anesthesiology (ASA) scores. All patients had postoperative followup visits at one, three, six, and 12 months. Our evaluation included the International Prostate Symptom Score (IPSS), quality of life (QoL) assessment, maximum urinary flow rate (Qmax), postvoid residual volume (PVR), and catheter-free status. RESULTS: One-hundred-sixty-eight males who underwent GreenLight laser prostatectomy were included. The non-octogenarian group consisted of 111 patients and the octogenarian group comprised 57 individuals. Based on ASA scores, most octogenarians were deemed high-risk (ASA III: 91.2%), while over half of non-octogenarians were lower-risk (ASA II: 53.2%) (p<0.001). Intraoperative parameters, including operative time, vaporization time, lasing time, and energy did not differ significantly between groups. There was no difference in the proportion of intraoperative complications between non-octogenarians and octogenarians (0.9% vs. 3.5%). Postoperative complications were not statistically significant between the two groups (p=0.608). There was also no observed difference in the proportion of patients requiring readmission (p=0.226) or retreatment (p=1.0). CONCLUSIONS: GreenLight laser prostatectomy is a safe and effective treatment for BPH regardless of age. It provides similar surgical and functional outcomes as younger men while maintaining the QoL of octogenarians. [ABSTRACT FROM AUTHOR]

The Moringa seeds waste (MSW), which resulted from the oil extraction industry, contains many varieties of natural organic components such as flavonoid, tannins, phenolic and hydrolyzable carbohydrates. The MSW could be considered a promising and an efficient green adsorbent for wastewater treatment as it reduces the environmental impact of hazardous chemicals existing in the industrial wastewater. The present work is designated to clarify the possibility of using MSW for the removal of industrial dispersed red 60 (DR60) and Congo Red (CR) dyes from aqueous solutions. The factors affecting the adsorption process such as initial dye concentration, catalyst weight, pH value, and solution temperature were investigated. It was found that the adsorption rate for both dyes was very high at the initial stages of the process and then decreases until reaches the equilibrium. The adsorption rate of the DR60 dye was not affected by catalyst weight, pH or the solution temperature. Whereas the percentage of the CR dye removal is found to be 100% for all dyes concentrations except for the CR dye with high initial concentration (100 mg/L), which reached only 85.3%. It was observed that the adsorption % of CR dye increases by increasing the temperature from 25 to 40 °C. With more increases in the reaction temperature from 40 to 80 °C, the CR removal decreases from 88.7 to 57.7%, respectively. This behavior can be attributed to the desorption behavior of the adsorbed dye molecules at a higher temperature. Accordingly, the optimum temperature for the CR dye adsorption is found at 40 °C. A detailed study of the dye adsorption isotherms and kinetics was carried out and the results show that the dyes adsorption isotherms and kinetics are followed by Freundlich and pseudo-second-order models. Maximum amounts of dyes adsorbed were found to be 170.7 and 196.8 mg/g for both CR and DR60 dyes, respectively, at 100 mg/L concentration, 25 °C and pH 7. The overall rate of adsorption process seems to be controlled by a chemical process mechanism involving valence forces through exchange or sharing of electrons between dyes and MSW adsorbent.

Background: Airway obstruction by malignant tumors may lead to dyspnea, cough, hemoptysis, atelectasis and pneumonia. Aim: The aim was to assess safety and efficacy of ethanol injection in debulking of endobronchial malignant tumors. Patients and methods: It included 20 patients with endobronchial malignant tumors and divided into 2 groups randomly: group A; 10 patients subjected to ethanol injection plus chemotherapy and group B; included 10 patients treated with chemotherapy alone. Results: There was a significant improvement in dyspnea, cough and hemoptysis scores in group A after the end of the study (P1: 0.004, 0.014 and 0.014 respectively) and a significant improvement in group A compared with group B 2 weeks after the last session of chemotherapy as regard dyspnea and cough (P2
