The study’s aim was to find preoperative factors that could predict the likelihood of achieving intraoperative Trifecta and build a surgical nomogram. <strong>Methods:</strong> We retrospectively evaluated 122 patients who underwent LPN. Preoperative factors like age, sex, body-mass index (BMI), kidney function, tumor characteristics (R.E.N.A.L. score) and Charlson-Comorbidity-Index (CCI) were recorded. Intraoperative complication (IOC) was graded according to the Rosenthal classification. R software was used to find a predicting model for achievement of Trifecta using preoperative variables and a nomogram was built. <strong>Results: </strong>The surgical features include median EBL of 100 ml having 6.5% bleed > 500 ml, median WIT of 12 minutes having 7.3% more than 20 minutes. There was recorded a 12.3% IOC with a mean Rosenthal’s grade of 0.2. Intraoperative Trifecta was achieved in 105 patients (86%) and three preoperative factors were chosen for the predictive model: BMI (p = 0.041), CCI (p = 0.037) and RENAL score (p = 0.002). A nomogram was generated and the ROC-AUC of the model was 75.8%. <strong>Conclusion:</strong> We have defined an intraoperative Trifecta concept as the achievement of EBL < 500 ml, WIT < 20 minutes and minimal changes of the intraoperative course. A nomogram was developed from preoperative factors like BMI, CCI and R.E.N.A.L. score. It can be used to estimate the probability of Trifecta achievement in patients treated with LPN.展开更多

There is however paucity of studies that compares the trifecta outcome between screen detected and patients presenting with lower urinary symptoms with localized prostate cancer after radical prostatectomy. This study compares the trifecta outcomes between these two groups after an open retropubic radical prostatectomy. Methodology: This is a retrospective study, on the trifecta outcomes (urinary continence, erectile function, and cancer control) of consecutive patients that had open radical retropubic prostatectomy for localized prostate cancer by a single surgeon. Patients were grouped into screen detected and presentation with lower urinary symptoms or retention of urine. The parameters considered were the age of the patients, the total prostate specific antigen (tPSA) at presentation, the clinical T stage, the Gleason score of prostate biopsies, the risk categories using the D’Amico risk groups and the trifecta outcomes after the procedure. Results: In all, 119 patients met the criteria for inclusion. The median follow up was 63.5 months (range 12 - 156 months). Of these 40.3% of the patients were diagnosed through screening with elevated PSA while 59.7% had presented with symptoms of lower urinary tract obstruction. The mean age for the patients was 60.8 ± 6.5 years, median PSA 12.6 ng/ml (IQR 8.6 - 19.7) and median prostate weight of 50.0 (IQR 40.0 - 60 g). The urinary continence rate after the procedure was 93.3%, erection rate of 81.5%, cancer control rate of 71.4% and trifecta achieved in 57.1%. Comparing the screening and the symptomatic cases, the urinary continence rate was 91.7% vrs 94.3%;erectile function rate was 79.2% vrs 83.1%;cancer control 68.8% vrs 73.2% and trifecta achieved in 58.3% vrs 56.3%. There was no statistically significant difference between the two groups in terms of urinary continence p = 0.564, erection function p = 0.588, cancer control p = 0.595, and achieving trifecta p = 0.829. Conclusion: Patients with localized prostate cancer presenting with lower urinary symptoms compared to screen detected patients have similar outcomes in terms of urinary Continence, erectile function, cancer control and trifecta after open radical retropubic prostatectomy.展开更多
