Cribriform Pattern of The Prostate Adenocarcinoma: Sensitivity of Multiparametric MRI.

Background: The aim of this study was to investigate the diagnostic performance of mpMRI for detecting cribriform pattern prostate cancer.

Materials And Methods: This study retrospectively enrolled 33 patients who were reported cribriform pattern prostate cancer at final pathology. The localization, grade and volumetric properties of the dominant tumors and areas with cribriform pattern at the final pathological specimens were recorded and the diagnostic value of mpMRI was evaluated on the basis of the cribriform morphology detection rate.

One step nucleic acid amplification (OSNA) for detection of lymph node metastasis during robotic radical prostatectomy for prostate cancer: A pilot study.

Introduction: The OSNA technique is based on reverse transcription loop-mediated DNA amplification for the detection of cytokeratin 19 (CK19) messen-ger RNA (mRNA). The purpose of our paper, which represents the first study in the literature, is to test the accuracy of this method in the detection of lymph node metastases in patients undergoing robotic radical prostatectomy with lymph node dis-section.

Methods: Our cohort consisted of patients that have undergone robotic radical prostatectomy with extended lymph node dissec-tion.

Safe use of intravesical bacillus Calmette-Guérin immunotherapy for bladder cancer during breastfeeding: a case report.

It is unknown whether intravesical bacillus Calmette-Guérin (BCG) is excreted in human breast milk. The US FDA advocates ceasing nursing due to potential adverse reactions. A lactating woman with bladder cancer who elected to receive intravesical immunotherapy with BCG and denied having ceased nursing her newborn is reported.

Impact of Refractive Errors on Da Vinci SI Robotic System.

Objective: To investigate the impact of refractive errors on binocular visual acuity while using the Da Vinci SI robotic system console.

Methods: Eighty volunteers were examined on the Da Vinci SI robotic system console by using a near vision chart. Refractive errors, anisometropia status, and Fly Stereo Acuity Test scores were recorded.

Management of prostate cancer patients during COVID-19 pandemic.

Prostate cancer patients' management demands prioritization, adjustments, and a tailored approach during the unprecedented SARS-CoV-2 pandemic. Benefit of care from treatment must be carefully weighed against the potential of infection and morbidity from COVID-19. Furthermore, urologists need to be cognizant of their obligation for wise consumption of restricted healthcare resources and protection of the safety of their coworkers.

Evaluation of Diagnostic Accuracy of Percutaneous Biopsy for Small Renal Masses and First Report of Post-Biopsy Adhesions: A Prospective Study.

Purpose: In the present study, we evaluate the biopsy results, complications due to biopsy, and the correlation with the final pathology specimen of 19 patients who had surgery for their small renal masses.

Materials And Methods: A total of 19 patients (11 male, 8 female) underwent percutaneous biopsy of their renal mass under ultrasound guidance. All patients subsequently underwent extirpative surgery.

Can SUVmax values of Ga-68-PSMA PET/CT scan predict the clinically significant prostate cancer?

Purpose: The intensity of prostate-specific membrane antigen (PSMA) expression increases as the tumor grade increases and the uptake of Ga-68-PSMA is higher in high-grade tumors. The aim of the present study was to evaluate the correlation of preoperative tracer uptake of primary tumor to Gleason Score in patients who underwent prostatectomy.

Patients And Methods: We retrospectively evaluated 141 patients who had Ga-68-PSMA positron emission tomography/computed tomography (PET/CT) imaging and who underwent prostatectomy.

Intra-surgical total and re-constructible pathological prostate examination for safer margins and nerve preservation (Istanbul preserve).

Purpose: To demonstrate a novel frozen section analysis technique during robot assisted radical prostatectomy with 2 distinct advantages: evaluation of the entire circumference and easier reconstruction for whole mount evaluation.

Material And Methods: Istanbul Preserve was performed on patients who underwent robotic prostatectomy with nerve sparing between 10/2014 and 7/2016. Gland was sectioned at 3-4mm intervals from apex to bladder neck.

Prevention of Urethral Retraction with Stay Sutures (PURS) During Robot-Assisted Radical Prostatectomy Improves Early Urinary Control: A Prospective Cohort Study.

Objective: To evaluate early continence rates with a novel modified vesicourethral anastomosis technique based on prevention of urethral retraction using anastomosis sutures as stay sutures (PURS) during robot-assisted radical prostatectomy.

Materials And Methods: Sixty patients operated by a single surgeon were enrolled and data collected prospectively. This cohort was compared with another consecutive 60 patients operated with standard anastomosis.

The accuracy of Ga-PSMA PET/CT in primary lymph node staging in high-risk prostate cancer.

Purpose: To assess the diagnostic accuracy of Ga-PSMA PET in predicting lymph node (LN) metastases in primary N staging in high-risk and very high-risk nonmetastatic prostate cancer in comparison with morphological imaging.

Methods: This was a multicentre trial of the Society of Urologic Oncology in Turkey in conjunction with the Nuclear Medicine Department of Cerrahpasa School of Medicine, Istanbul University. Patients were accrued from eight centres.

Robot-Assisted Partial Nephrectomy for T1b Tumors: Strict Trifecta Outcomes.

Background And Objectives: "Trifecta" in partial nephrectomy consists of negative surgical margins, minimal renal function decrease and absence of complications. In the present article, our single-center robot-assisted partial nephrectomy (RAPN) experience in T1b renal masses is reported in terms of strict Trifecta outcomes.

Methods: This is a retrospective analysis of patients with a tumor diameter between 4 and 7 cm (stage T1b), who underwent RAPN by a single surgeon.

Can We Accomplish Better Oncological Results with Robot-Assisted Radical Prostatectomy?

Surgical removal with radical prostatectomy has been a cornerstone for the treatment of prostate cancer and is associated with level 1 evidence for survival advantage compared with watchful waiting. Since the first structured robotic program was launched in 2000, robot-assisted radical prostatectomy (RARP) has had a rapid diffusion and surpassed its open radical prostatectomy (ORP) and laparoscopic radical prostatectomy (LRP) counterparts in the United States and is progressively expanding in other countries. Interestingly, this common acceptance of RARP was initially driven in the paucity of robust clinical evidence.

Procedural sedation and analgesia as an adjunct to periprostatic nerve block for prostate biopsy: A prospective randomized trial.

Background: To assess whether patient comfort could be increased by adding procedural sedation and analgesia (PSAA) to periprostatic nerve block (PNB) in patients undergoing transrectal ultrasound-guided prostatic biopsy (TRUS-PB).

Methods: This was a prospective, randomized (1:2) trial comparing PNB with the combination of PSAA+PNB in patients undergoing TRUS-PB. PNB was achieved by using lidocaine gel and lidocaine and bipuvacaine infiltration.

Core length in prostate biopsy: size matters.

Purpose: The diagnostic yield of prostate biopsy is limited. Increasing the number of cores enhances the cancer detection rate by sampling additional sites and obtaining more tissue. An alternative way to inspect more tissue would be to obtain longer cores.
