Bilateral peritoneal flaps reduce incidence and complications of lymphoceles after robotic radical prostatectomy with pelvic lymph node dissection-results of the prospective randomized multicenter trial ProLy.

Purpose:Prostate biopsy is mostly performed through the transrectal route worldwide and infectious complications may occur in up to 7% of cases. Therefore, alternative strategies to decrease infectious complications are needed. Our aim was to evaluate the effectiveness of intrarectal povidone-iodine cleansing plus formalin disinfection of the needle tip in decreasing infectious complications after transrectal ultrasound guided prostate biopsy.Materials and Methods:We conducted a prospective, single-center, phase III trial in patients undergoing transrectal ultrasound guided prostate biopsy randomized 1:1 to rectal mucosa cleansing with gauze soaked in 10% povidone-iodine solution wrapped around the gloved index finger and needle tip disinfection by immersion in a 10% formalin solution before each puncture vs control group. The primary end point was the rate of infectious complications defined as 1 or more of the following events: fever, urinary tract infection, or sepsis.Results:Overall, 633 patients were randomized to the intervention group and 623 to the control group. The infectious complication rate was 3.9% in the intervention group and 6.4% in the control group (RR 0.61; 95% CI 0.36-0.99; P = .049). The rates of sepsis, urinary tract infection, and fever were 0.3% vs 0.5% (P = .646), 2.3% vs 4.1% (P = .071), and 1.3% vs 1.9% (P = .443), respectively. The positive urine culture rate was 5.2% in the intervention group and 9% in the control group (RR 0.57; P = .015). There was no statistically significant difference between the groups regarding the occurrence of noninfectious adverse events.Conclusions:Intrarectal povidone-iodine cleansing plus formalin disinfection of the biopsy needle tip was associated with a reduction in infectious complications after transrectal prostate biopsy.

Objective: To identify the main hemorrhagic complications after percutaneous nephrolithotomy, as well as the results obtained with transcatheter arterial embolization (TAE) at an interventional radiology center. Materials and Methods: This was a retrospective analysis of patients undergoing TAE for the treatment of hemorrhagic complications after percutaneous nephrolithotomy. All patients underwent computed tomography angiography (CTA). Results: We evaluated a total of nine patients. At emergency department readmission, the most common symptom was macroscopic hematuria, which was seen in five patients. Three patients had an isolated pseudoaneurysm, two had a pseudoaneurysm together with active bleeding (perirenal hematoma), and one had a pseudoaneurysm together with arteriocalyceal fistula. Arteriovenous fistula was diagnosed in three patients and was not seen in combination with other vascular lesions. We did not identify arteriocalyceal fistula in isolation. Five patients underwent TAE with 6 × 15 mm and 6 × 20 mm microcoils. Four patients underwent TAE with n-butyl-2-cyanoacrylate and ethiodized oil. Follow-up CTAs revealed no complications. Conclusion: Because of its high diagnostic accuracy, CTA provides the interventional radiologist with valuable data for individualized therapeutic planning. The TAE procedure is safe and effective. It can therefore be used as a first-line treatment for hemorrhagic complications resulting from percutaneous renal procedures.

Rev Bras Cir Cardiovasc | Braz J Cardiovasc SurgRev Bras Cir Cardiovasc 2013;28(2):167- Abstract Objectives The purpose of our study was to establish, with an entirely noninvasive method, transthoracic Doppler echocardiography, criteria for patency of composite left internal thoracic artery grafts when placed on the left anterior descending artery and other branches of the left coronary system.Methods: The control group comprised 20 patients with single graft and 20 patients with composite graft; all forty having their patency confirmed by coronary angiogram (CA). In this control group, two Doppler echocardiographic variables, diastolic mean velocity-time and integral diastolic peak velocity to systolic peak velocity ratio were recorded. For each variable, established cut-off points were established, using the ROC (Receiver Operator Characteristic) curves, to identify criteria which could differentiate the composite grafts. Only patients with composite grafts were included in the 159-patients study group. The criteria established by the cut-off points in the control group were then applied to detect patency using a diastolic fraction of ≥ 0.5 as the gold standard. The sensitivity, specificity, and positive and negative predictive values of these two criteria were determined.Results: In the control group, cut-off points of 0.71 and 0.09m were established for the diastolic peak velocity/systolic peak velocity ratio and for diastolic mean velocity-time integral, respectively. In the study group phase, the sensitivity and negative predictive value of the diastolic peak velocity/systolic peak velocity ≥ 0.71 criterion were 36% and 11%, respectively. Diastolic mean velocity-time integral ≥ 0.09m criterion, were 40% and 10.48%. The specificities and positive predictive values of each criterion were 100%.
