Accuracy of PET-choline in nodal staging of localized very high-risk prostate cancer.

Objectives: Localized very high-risk prostate cancer (VHR PCa) has long suffered from the inex-istence of good lymph node staging methods other than invasive surgery, as computed tomogra-phy has low sensitivity for nodal disease. With the rising use of positron emission tomography (PET), it is clinically meaningful to know its value for these patients. Our goal was to evaluate the real-life diagnostic accuracy of PET Choline in nodal staging, comparing it with the gold standard of extended pelvic lymph node dissection (ePLND).

Renal tumor biopsy does not increase the risk of surgical complications of minimally invasive partial nephrectomy.

Background: For patients with cT1 renal lesions, Partial Nephrectomy (PN) is the gold standard treatment. However, 20% of small renal masses are benign, situation in which the PN is an overtreatment. The percutaneous Renal Tumor Biopsy (RTB) may lower the risk of overtreatment as there is a 90% concordance rate on histotype between the RTB and the final pathology.

Neoadjuvant chemotherapy does not increase peri-operative morbidity following radical cystectomy.

Objective: To determine whether use of neoadjuvant chemotherapy (NAC) is associated with a higher risk of post-operative complications following radical cystectomy (RC) for bladder cancer (BCa).

Materials And Methods: We retrospectively reviewed records of patients undergoing RC for non-metastatic urothelial BCa at 13 tertiary care centres from 2007-2019. Patients who received NAC ('NAC + RC' group) were compared with those who underwent upfront RC ('RC alone' group) for intra-operative variables, incidence of post-operative complications as per the Clavien-Dindo classification (CDC) and rates of re-admission and re-intervention.

Robotic-Assisted Partial Nephrectomy: Techniques to Improve Clinical Outcomes.

To summarize current options available for robot-assisted partial nephrectomy RECENT FINDINGS: Partial nephrectomy (PN) is a standard treatment option for management of cT1 renal masses. It may be carried out by multiple approaches. Robot-assisted (RA) PN is one such option.

[Rectourethral fistula treatment using the modified York Mason technique: Failure factors assessment].

Objectives: To assess surgical outcomes and failure factors in the management of rectourethral fistulas treated surgically with the modified York Mason technique based on our center's 25 years of experience.

Methods: From 1997 to 2021, in a single center study, a total of 35 consecutive patients, underwent rectourethral fistula cure, using the modified York Mason technique. Preoperative patient data, surgical outcomes and failure factors were assessed.
