Safety and feasibility of thullium laser transurethral resection of prostate for the treatment of benign prostatic enlargement in overweight patients

Objective: We aimed to determine safety and feasibility of thulium laser transurethral vapoenucleation of prostate (ThuVEP) for treatment of obese patients affected by benign prostatic hyperplasia (BPH). Methods: We retrospectively analysed data of 452 patients with BPH who underwent ThuVEP from February 2012 to March 2016 in a single center. Patients were divided into three groups according to body mass index (BMI, kg/m2): Normal weight (18.5 64 BMI < 25; Group A), overweight (25 64 BMI < 30; Group B) and obese (BMI 65 30; Group C), for a total of 412 patients evaluable for this study. Preoperative total serum prostate-specific antigen (PSA), digital rectal examination of the prostate, transrectal ultrasound (TRUS), renal ultrasound, urine culture, uroflowmetry, International Prostate Symptoms Score (IPSS), and Quality of Life (QoL) score were analyzed. Post-operative complications, hospital stay and days of catheterization, questionnaires and uroflowmetry at 1 and 3 months after surgery were evaluated. Preoperative data, surgical outcomes, complication rate and clinical outcomes were compared between groups. Results: The median age of patients was 69 years (Interquartile Range [IQR 10]). The preoperative median IPSS among groups was 19 (IQR 8.75), 20 (IQR 10), and 18 (IQR 10) respectively. At 1 and 3 months of follow-up, this value was 8 (IQR 7), 8 (IQR 4), 7 (IQR 5) and 5 (IQR 6.25), 5 (IQR 6), 6 (IQR 5), respectively (all p between groups > 0.05). There was no statistically significant difference among three groups as for hospital stay and days of catheterization (p > 0.05). Conclusion: Our results showed that ThuVEP was safe and feasible even in overweight patients with substantially enlarged prostate

Comparison of perioperative outcomes between open and robotic radical cystectomy: a population based analysis

Introduction: Radical cystectomy represents the standard of care for muscle-invasive bladder cancer (MIBC). Due to its novelty the use of robotic radical cystectomy (RARC) is still under debate. We examined intraoperative and postoperative morbidity and mortality in addition to impact on length of stay (LOS) and total hospital charges (THCGs) of RARC compared with open radical cystectomy (ORC). Materials and Methods: Within National Inpatient Sample (2008-2013), we identified patients with nonmetastatic bladder cancer treated with either ORC or RARC. We relied on inverse probability of treatment weighting to reduce the effect of inherent differences between ORC vs RARC. Multivariable logistic regression (MLR) and multivariable Poisson regression (MPR) models were used. Results: Of all 10,027 patients, 12.6% underwent RARC. Between 2008 and 2013, RARC rates increased from 0.8% to 20.4% [estimated annual percentage change (EAPC): +26.5%, 95% confidence interval (CI): +11.1 to +48.3; p=0.035] and RARC THCGs decreased from 45,981 to 31,749 United States dollars (EAPC: -6.8%, 95% CI: -9.6 to -3.9; p=0.01). In MLR models RARC resulted in lower rates of overall complications [odds ratio (OR): 0.6; p<0.001] and transfusions (OR: 0.44; p<0.001). In MPR models, RARC was associated with shorter LOS (relative risk 0.91; p<0.001). Finally, higher THCGs (OR: 1.09; p<0.001) were recorded for RARC. Data are retrospective and no tumor characteristics were available. Conclusion: RARC is related to lower rates of overall complications and transfusions rates. In consequence, RARC is a safe and feasible technique in select MIBC patients. Moreover, RARC is associated with shorter LOS, although higher THCGs
