Introduction: The goal of the study is to evaluate and report on the third-generation da Vinci surgical (Si) system malfunctions. Methods: A total of 1228 robotic surgeries were performed between January 2012 and December 2015 at our academic centre. All cases were performed by using a single, dual console, four-arm, da Vinci Si robot system. The three specialties included urology, gynecology, and thoracic surgery. Studied outcomes included the robotic surgical error types, immediate consequences, and operative side effects. Error rate trend with time was also examined.

PVP is an effective, safe, and durable treatment for men in acute urinary retention (AUR) with a catheter-free rate of 96%. The improvement is similar to those who did not present in AUR.

Purpose: Partial gland ablation (PGA) using high-intensity focused ultrasound (HIFU) is currently under investigation for clinically significant prostate cancer (Cs-PCa). Our primary objective was to assess the role of systematic control biopsies following HIFU-PGA in a cohort of Cs-PCa patients. Materials and Methods: We studied a single-center retrospective cohort of 77 men treated with HIFU-PGA between October 2015 and December 2019. Patients with unilateral Cs-PCa, defined as Gleason grade group (GGG) 2, with visible lesion on multiparametric magnetic resonance imaging (mpMRI) and prostate specific antigen (PSA) 15 ng/ml were included. All patients underwent mpMRI with systematic and targeted biopsies before and after HIFU-PGA. The primary outcome was the rate of Cs-PCa at control biopsy within 1 year of treatment. Logistic regression was performed to identify predictive factors of our primary outcome. Results: Median age was 67 years (IQR 61e71), median PSA was 7 ng/ml (IQR 5.5e8.9). Pre-treatment biopsies revealed 48 (62.3%) GGG2 lesions, 24 (31.2%) GGG3 and 5 (6.5%) GGG4 lesions. Cs-PCa was found in 24 (31.2%) patients at systematic control biopsy post-HIFU; Cs-PCa was in the treated lobe for 18 (27%) patients. No variables were identified as significant predictors of Cs-PCa at control biopsy, including PSA kinetics and control mpMRI. Median followup time was 17 months (95% CI 15e21). Median time to any retreatment was 32 months (95% CI 23-42). Conclusions: Systematic control biopsy within a year after PGA for Cs-PCa can identify the presence of residual Cs-PCa in up to a third of patients. From our early experience, control biopsy should be systematically offered patients regardless of PSA kinetics or control mpMRI results.

Despite older age, greater comorbidity, and significant use of anticoagulants, HMR men who undergo photoselective vaporization benefit from symptom improvement and show no clinical difference in adverse event profiles. GreenLight-XPS produces similar short-term outcomes in patients with significant comorbidities when compared with healthy patients.

Introduction: Transurethral resection of the prostate (TURP) is still considered the gold standard surgical treatment for symptomatic benign prostatic hyperplasia (BPH). However, photoselective vaporization of the prostate (PVP) has gained widespread global acceptance in national guidelines as a safe and effective alternative option. Nevertheless, further evidence is required to assess the durability of Greenlight PVP. Herein, we reported our five years PVP experience with the Greenlight 180W XPS laser system. Methods: A retrospective analysis was conducted on a prospectively gathered database of 370 consecutive included patients who underwent PVP using Greenlight XPS-180 W laser system (Boston Scientific, Boston, MA, U.S.) performed by a single experienced laser surgeon between 2011 and 2016. Preoperative characteristics, intervention parameters, postoperative functional, uroflowmetry outcomes, and complications were collected. Outcomes are reported over a period of five years. Results: Mean age was 68 years with a mean prostate volume of 78.8 cc (95% confidence interval [CI] 70.9-78.7]). The mean followup was 59.4 months (55.4-63.5). Mean energy, operative time and energy/cc were 270.2 kJ (255.2-285.2), 62.7 minutes (59.6-65.7), and 3.7 kJ/cc (3.6-3.9), respectively. Compared to preoperative values, International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), and post-void residual (PVR) parameters were significantly improved and sustained over the five postoperative years. To note, only 66 patients (out of 370) had a complete five-year

Background Biliary mucinous cystic neoplasms are rare cystic lesions of the liver which carry pre-malignant potential. Given the scarcity of reports in the literature, they pose a considerable challenge to clinical management, particularly with regards to accurate pre-operative diagnosis. Case presentation We present the case of a 37-year-old Tunisian woman who presented with subacute right upper quadrant pain and a large multi-loculated cystic lesion, most consistent with a hydatid cyst. She underwent an open right hepatectomy, and pathology surprisingly revealed a biliary mucinous cystadenoma. Herein, we review the current literature on biliary mucinous cystic neoplasms, with a particular emphasis on diagnostic investigations, key radiological features and optimal treatment modalities. Conclusion Biliary mucinous cystic neoplasms require a high index of suspicion and should be managed with complete surgical resection, as conservative techniques are associated with high recurrence rates. Considering the potential for malignant transformation, periodical surveillance imaging is recommended in the post-operative period.

Bladder-sparing protocols (BSP) have been gaining widespread popularity as an attractive alternative to radical cystectomy (RC) for muscle-invasive bladder cancer. Unimodal therapies are inferior to multimodal regimens. The most promising regimen is trimodal therapy (TMT), which is a combination of maximal transurethral resection of bladder tumor (TURBT), radiotherapy, and chemotherapy. In appropriately selected patients (low volume unifocal T2 disease, complete TURBT, no hydronephrosis and no carcinoma-in-situ), comparable oncological outcomes to RC have been reported in large retrospective studies, with a potential improvement in overall quality of life (QOL). TMT also offers the possibility for definitive therapy for patients who are not surgically fit to undergo RC. Routine biopsy of previous tumor resection is recommended to assess response. Prompt salvage RC is required in non-responders and for recurrent muscle-invasive disease, while non-muscle-invasive recurrence can be managed conservatively with TURBT +/− intravesical BCG. Long-term follow-up consisting of routine cystoscopy, urine cytology, and cross-section imaging is required. Further studies are warranted to better define the role of neoadjuvant or adjuvant chemotherapy in the setting of TMT. Finally, future research on predictive markers of response to TMT and on the integration of immunotherapy in bladder sparing protocols is ongoing and is highly promising.
