Post-operative acute urinary retention after greenlight laser. Analysis of risk factors from a multicentric database

Purpose: Greenlight laser is a mini-invasive technique used to treat Benign Prostatic Obstruction (BPO). Some of the advantages of GreenLight photoselective vaporization (PVP) are shorter catheterization time and hospital stay compared to TURP. Post-operative acute urinary retention (pAUR) leads to patients' discomfort, prolonged hospital stay and increased health care costs. We analyzed risk factors for urinary retention after GreenLight laser PVP. Materials and methods: In a multicenter experience, we retrospectively analyzed the onset of early and late post-operative acute urinary retention in patients undergoing standard or anatomical PVP. The pre-, intra- and post-operative characteristics were compared betweene patients who started to void and the patients who developed post-operative urinary retention. Results: The study included 434 patients suitable for the study. Post-operative acute urinary retention occurred in 39 (9%). Patients with a lower prostate volume (P < .001), an adenoma volume lower than 40 mL (P < .001), and lower lasing time (P = .013) had a higher probability to develop pAUR at the univariate analysis. The multivariate logistic regression confirmed that lower lasing time (95% CI: 0.86-0.99, OR = 0.93, P = .046) and adenoma volume (95% CI: 0.89-0.98, OR = 0.94, P = .006) are correlated to pAUR. Furthermore IPSS ≥ 19 (95% CI: 1.19- 10.75, OR = 2.27, P = .023) and treatment with 5-ARI (95% CI: 1.05-15.03, OR = 3.98, P = .042) are risk factors for pAUR. Conclusion: In our series, post-operative acute urinary retention was related to low adenoma volume and lasing time, pre-operative IPSS ≥ 19 and 5-ARI intake. These data should be considered in deciding the best timing for urethral catheters removal

Association between selenium and lycopene supplementation and incidence of prostate cancer: Results from the post-hoc analysis of the procomb trial

Background Many potential chemopreventive agents have been used in PCa prevention, including selenium (Se) and lycopene (Ly). However, their role has been matter of debate over the years, due to potential of promotion of PCa. Purpose In this study we aimed at evaluating the incidence risk of prostate cancer (PCa) in a cohort of patients treated with Se and Ly. Methods The Procomb trial design has been previously published (ISRCTN78639965). From April 2012 to April 2014 209 patients were followed and underwent prostate biopsy when PSA ≥4 ng/ml and/or suspicion of PCa. The all cohort was composed by patients treated with Se and Ly (Group A = 134 patients) and control (Group B = 75 patients). Results During the follow-up time of 2 years, a total of 24 patients (11.5%) underwent prostate biopsy, of which 9 (4.3%) where diagnosed with PCa and 15 (7.2%) where diagnosed with benign prostatic hyperplasia. We did not observe statistical differences in terms of mean changes of PSA between the two groups (p-value for trend = 0.33). The relative risk (RR) for PCa was 1.07 and 0.89 in group A and B, respectively (p = 0.95). At the multivariate Cox regression analysis supplementation with Se and Ly was not associated with greater risk of PCa (hazard ratio: 1.38; p = 0.67). Conclusion In this analysis we did not show evidences supporting a detrimental role of Selenium and Lycopene supplementation in increasing PCa after 2 years of therapy, nor supporting a protective role

Fournier's gangrene: Clinical case and review of the literature

Fournier's gangrene is a life-threatening acute necrotizing fasciitis of perianal,genitourinary and perineal areas. Nowadays, is well known that Fournier gangrene is almost never an idiopathic disease. In this article we report a case of a 70-year-old patient that initially was not treated properly. The gold standard therapy of the Fournier's gangrene remains today a complete, early and extended surgical debridement

Serenoa repens + selenium + lycopene vs tadalafil 5 mg for the treatment of lower urinary tract symptoms secondary to benign prostatic obstruction: a Phase IV, non-inferiority, open-label, clinical study (SPRITE study)

Objective: To compare in a randomised, open-label, non-inferiority clinical study, the efficacy and tolerability of Serenoa repens (SeR) + selenium (Se) + lycopene (Ly) (SeR-Se-Ly) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms (LUTS). Patients and methods: From May 2015 to January 2017, 427 patients were enrolled in 21 different centres (International Standard Randomised Controlled Trial Number Register [ISRCTN] 73316039). Inclusion criteria included: age between 50 and 80 years, International Prostate Symptom Score (IPSS) ≥12, maximum urinary flow rate (Qmax) ≤ 15 mL/s, and post-void residual (PVR) <100 mL. Patients were randomised into two groups in a 2:1 ratio: Group A (SeR-Se-Ly, 1 tablet daily for 6 months) and Group B (tadalafil 5 mg, 1 tablet daily for 6 months). The primary endpoint of the study was the non-inferior variation in the IPSS and Qmax in Group A vs Group B after 6 months of treatment. Results: In all, 404 patients completed the full protocol. When comparing both therapies, Group A was statistically not inferior to Group B considering the median change in IPSS (−3.0 vs −3.0; P < 0.01), IPSS quality of life (−2.0 vs −2.0; P < 0.05), and Qmax (2.0 vs 2.0 mL/s; P < 0.01). We found statistically significant differences in the increase of at least 3 points in Qmax (38.2% vs 28.1%; P = 0.04) and of at least 30% of Qmax (39.2% vs 27.3%; P < 0.01) in Group A compared to Group B. The percentage of patients with an increase of at least 3 points in the IPSS and a decrease of at least 25% of the IPSS was not statistically different between the two groups. For adverse events, four patients in Group A (1.44%) and 10 in Group B (7.81%) (P < 0.05) reported side-effects. Conclusion: We have shown that treatment with SeR-Se-Ly was not inferior to tadalafil 5 mg for improving IPSS and Qmax in men with LUTS

Efficacy and safety profile of GreenLight laser photoselective vaporization of the prostate in ≥ 75 years old patients: results from the Italian GreenLight Laser Study Group

Background: Benign Prostatic Obstruction (BPO) is the most common non-malignant urological condition among men and its incidence rise with age. Among prostate treatments, GreenLight laser seems to reduce bleeding and would be safer in the aging population. Aims: We aimed to compare the functional outcomes and safety profile of < 75 years old (Group A) and ≥ 75 years old (Group B) patients. Methods: In a multicenter setting, we retrospectively analyzed all the patients treated with GreenLight Laser vaporization of the prostate (PVP). Results: 1077 patients were eligible for this study. 757 belonged to Group A (median age 66 years) and 320 to Group B (median age 78 years). No differences were present between the two groups in terms of prostate volume, operative time, hospital stay, PSA decrease over time after surgery, complications and re-intervention rate with a median follow-up period of 18 months (IQR 12-26). Nevertheless, focusing on complications, GreenLight laser PVP demonstrated an excellent safety profile in terms of hospital stay, re-intervention and complications, with an overall 29.6% complication rate in older patients and only two cases of Clavien III. Functional outcomes were similar at 12 month and became in favor of Group A over time. These data are satisfactory with a Qmax improvement of 111.7% and an IPSS reduction of 69.5% in older patients. Discussion and conclusions: GreenLight laser photoselective vaporization of the prostate is a safe and efficient procedure for all patients, despite their age, with comparable outcomes and an equal safety profile

Predictors of re-intervention after greenlight laser photoselective vaporization of the prostate: multicenter long/mid-term follow-up experience

Aim: Greenlight photoselective vaporization of the prostate (PVP) is considered a safe alternative to transurethral resection of the prostate (TURP) in men with lower urinary tract symptoms (LUTS) and a prostate volume of 30-80 mL for the comparable short- and mid-term results. Long-term re-treatment rate is still being debated.Methods: We retrospectively reviewed greenlight PVP procedures in a multi-institutional database from September 2011 to December 2019 collecting data on patients requiring re-intervention with a follow-up period of at least 12 months.Results: Among 867 patients with a median follow-up period of 32.5 months (interquartile range: 20.0-49.0 months), 35 patients (4%) required re-intervention. Patients requiring re-intervention had a prostate volume ≥ 100 mL in 28.6% of cases (P = 0.002). Preoperative urethral stricture and incidence of early complications were more frequent in the re-treatment group (P = 0.027 and P = 0.006). In the re-treatment group, 22 patients required an endoscopic intervention for bladder neck or prostatic fossa contracture (2.5% of the study population). The remaining 13 patients in the re-treatment group underwent TURP or PVP for LUTS relapse (1.5%). In the univariate and multivariate logistic regression models, only prostate volume ≥ 100 mL (P = 0.003 and P = 0.010), preoperative urethral stricture (P = 0.013 and P = 0.036), and occurrence of early complications (P = 0.008 and P = 0.024) correlated with re-intervention.Conclusion: Greenlight PVP has good functional long/mid-term results. The presence of preoperative urethral stricture and the occurrence of early complications correlate with the risk of late re-treatment. In patients with prostate ≥ 100 mL, the enucleation technique may be superior to vaporization in terms of lower long-term risk of re-intervention for LUTS relapse
