The predictive impact of hematological inflammatory markers in detecting prostate cancer in patients with PI-RADS 3 lesions on multiparametric magnetic resonance imaging.

Background: The diagnostic accuracy of suspicious lesions that are classified as PI-RADS 3 in multiparametric prostate magnetic-resonance imaging (mpMRI) is controversial. This study aims to assess the predictive capacity of hematological inflammatory markers such as neutrophil-lymphocyte ratio (NLR), pan-immune-inflammation value (PIV), and systemic immune-response index (SIRI) in detecting prostate cancer in PI-RADS 3 lesions.

Methods: 276 patients who underwent mpMRI and subsequent prostate biopsy after PI-RADS 3 lesion detection were included in the study.

Inflammation indexes and machine-learning algorithm in predicting urethroplasty success.

Purpose: To assess the predictive capability of hematological inflammatory markers for urethral stricture recurrence after primary urethroplasty and to compare traditional statistical methods with a machine-learning-based artificial intelligence algorithm.

Materials And Methods: Two hundred eighty-seven patients who underwent primary urethroplasty were scanned. Ages, smoking status, comorbidities, hematological inflammatory parameters (neutrophil-lymphocyte ratios, platelet-lymphocyte ratios [PLR], systemic immune-inflammation indexes [SII], and pan-immune-inflammation values [PIV]), stricture characteristics, history of previous direct-visual internal urethrotomy, urethroplasty techniques, and grafts/flaps placements were collected.

Is testosterone deficiency a predictive factor for recurrence of urethral stricture?

Background: Testosterone plays a vital role in maintaining tissue homeostasis, and testosterone deficiency may potentially influence the likelihood of urethral stricture recurrence.

Objectives: To evaluate the prognostic value of testosterone levels in the recurrence after direct visual internal urethrotomy in primary short segment bulbar urethral strictures and its clinical reflections.

Materials And Methods: A total of 723 patients who underwent direct vision internal urethrotomy between January 2000 and October 2022 were retrospectively analyzed.

Pan-immune-inflammation value as a prognostic tool for overall survival and disease-free survival in non-metastatic muscle-invasive bladder cancer.

Purpose: To evaluate the association between preoperative pan-immune inflammation value (PIV) and overall survival (OS) and disease-free survival (DFS) in patients who underwent radical cystectomy for non-metastatic muscle-invasive bladder cancer.

Methods: A total of 119 patients with non-metastatic muscle-invasive bladder cancer who underwent radical cystectomy at our institution between January 2014 and January 2022 were included in this retrospective study. PIV was calculated using the formula (monocyte count × neutrophil count × platelet count)/lymphocyte count.

Extensive penile glans and corpus spongiosum necrosis due to catheter traction following laparoscopic radical cystoprostatectomy: a rare case report and literature review.

Background: Penile glans and corpus spongiosum necrosis is an extremely rare urologic condition associated with substantial morbidity.

Case Presentation: We report a rare case presenting extensive penile glans and corpus spongiosum necrosis following catheter traction in a 71-year-old male patient who had a laparoscopic radical cystoprostatectomy for muscle-invasive bladder cancer. The patient has no preexisting diabetes mellitus or chronic renal failure.

Assessment of YouTube Videos about Urethral Stricture and Its Management.

Purpose: To evaluate the reliability, transparency, usability and technical quality of videos about urethral stricture and its management in the most common video-sharing website "YouTube".

Methods: We performed a video search on YouTube using the keywords "Urethral Stricture", "Internal Urethrotomy" and "Urethroplasty". After excluding the videos that did not meet the inclusion criteria, demographic data of each video was recorded and assessed with the validated DISCERN questionnaire, the Journal of the American Medical Association Benchmark Score (JAMAs) and the Global Quality Score (GQS).

Biopsy with Ureterorenoscopy Before Radical Nephroureterectomy is Associated with Increased Intravesical Recurrence in Urothelial Cancer Located in the Kidney.

Objective: Diagnostic ureterorenoscopy is used to identify upper tract urothelial cancer before radical nephro ureterectomy, especially for uncertain lesions in imaging modalities or urine cytology. However, diagnostic ureterorenoscopy can potentially cause intravesical tumor spillage and can increase intravesical recurrence rates. We aimed to investigate the impact of diagnostic ureterorenoscopy before radical nephroureterectomy, with and without biopsy, on intravesical recurrence rates of patients with upper tract urothelial cancer.

Predictive value of systemic immune-inflammation index in recurrent urethral strictures.

Purpose: To investigate the predictive value of systemic immune-inflammation index (SII) in recurrence of urethral stricture in patients undergoing internal urethrotomy.

Methods: In this two-center, retrospective study, 703 patients who had internal urethrotomy for urethral stricture were included. Demographic, clinical, and laboratory characteristics and operative data were obtained.

Management and outcomes of urethral stricture: single centre experience over 13 years.

Aim: To present a comprehensive summary of the diagnosis, treatment and follow-up process of patients who underwent open urethroplasty in our tertiary referral center for the treatment of urethral stricture in the last 13 years.

Materials And Methods: Two hundred and forty-five (245) patients who underwent open urethroplasty between January 2008 and June 2021 were retrospectively analysed. Detailed history, physical examination, uroflowmetry, retrograde urethrography and/or voiding cystourethrography and/or urethroscopy were used throughout the preoperative diagnosis process.

Is neutrophil to lymphocyte ratio a predictive factor for recurrence of urethral stricture?

Introduction: Due to spongiofibrosis and inflammatory processes underlying the pathogenesis of urethral stricture, it is possible that the neutrophil-lymphocyte ratio (NLR) may give essential information about the course of the disease and recurrence possibilities. Our study aims to evaluate the correlation between NLR and recurrence rates.

Methods: A total of 512 patients who underwent direct visual internal urethrotomy (DVIU) due to urethral stricture in our clinic between February 2010 and January 2018 were evaluated retrospectively.

Surgical management of renal cell carcinoma with associated tumor thrombus extending into the inferior vena cava: A 10-year single-center experience.

Objective: Renal cell carcinoma (RCC) is a tumor that has a tendency of vascular invasion by extending to the inferior vena cava (IVC) after the renal vein. The total resection of the renal tumor and tumor thrombus is considered the optimal treatment. In our study, we aimed to present the results related to 34 consecutive cases of RCC with tumor thrombus.
