The Role of Novel Bladder Cancer Diagnostic and Surveillance Biomarkers—What Should a Urologist Really Know?
The aim of this review is to analyze and describe the current landscape of bladder cancer diagnostic and surveillance biomarkers. We researched the literature from 2016 to November 2021 to find the most promising new molecules and divided them into seven different subgroups based on their function and location in the cell. Although cystoscopy and cytology are still the gold standard for diagnosis and surveillance when it comes to bladder cancer (BCa), their cost is quite a burden for national health systems worldwide. Currently, the research is focused on finding a biomarker that has high negative predictive value (NPV) and can exclude with a certainty the presence of the tumor, considering…
Percutaneous Nephrostomy Catheter Misplacement into Inferior Vena Cava in a Patient with a Horseshoe Kidney
Background: Percutaneous nephrostomy (PCN) is commonly indicated for upper urinary tract drainage in case of obstruction or fistula. Only a few cases of PCN catheter misplacement into the inferior vena cava (IVC) have been published. Case Presentation: We report a case of a PCN catheter misplaced into the IVC through a fistula between the urinary tract and an ipsilateral renal vein in a patient with horseshoe kidney, after bedside urgent replacement for hemorrhage and hemorrhagic shock. Conclusion: Although a nephrostomy Foley catheter can be used for adequate urinary drainage and hemostatic purposes after percutaneous nephrolithotomy, its placement should be always verified through antegra…
Comparison of Fluoroquinolones and Other Antibiotic Prophylaxis Regimens for Preventing Complications in Patients Undergoing Transrectal Prostate Biopsy

A multi-institutional cohort of 1150 patients who underwent TRUSBx was retrospectively analyzed. Procedures were performed between 2017 and 2019 (before and after the EMA warning about the use of fluoroquinolones for the antibiotic prophylaxis of patient candidates to TRUSBx). The primary endpoint was the occurrence of infective complications, including sepsis and/or fever. The population was stratified according to the antibiotic prophylaxis adopted: fluoroquinolones (levofloxacin, ciprofloxacin, prulifl…
Risk of Virus Contamination Through Surgical Smoke During Minimally Invasive Surgery: A Systematic Review of the Literature on a Neglected Issue Revived in the COVID-19 Pandemic Era
Abstract Context The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. Objective To evaluate the risk of virus spread due to surgical smoke during surgical procedures. Evidence acquisition We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke fr…
Congenital penile curvature: dermal grafting procedure to prevent penile shortening in adults.
Objectives: We report the results of a derma graft corporoplasty in a selected group of patients with congenital penile curvature (CPC) who refused a simple plication technique for the risk of penile shortening, even if minimal. Methods: Between January 1995 and January 2004, 15 potent patients with CPC underwent corporoplasty with inguinal derma graft, with or without tunica albuginea plication.

Segmental Ureterectomy Versus Radical Nephroureterectomy in Older Patients Treated for Upper Tract Urothelial Carcinoma
Introduction: The world population is ageing and surgical procedures for older patients are associated with higher perioperative morbidity and mortality rates than in younger patients. Segmental ureterectomy (SU) has been proposed as an alternative to radical nephroureterectomy (RNU) for selected upper tract urothelial carcinomas (UTUC), to reduce post-operative morbidity, and preserve renal function. The aim of this study was to compare RNU and SU in terms of post-operative complications, functional outcomes, and overall survival (OS) in older patients treated for UTUC. Materials and methods: Data of patients aged 75 years or older and treated for UTUC were included. The primary outcome wa…

Preoperative risk factors for postoperative delirium (POD) after urological surgery in the elderly
The aim of this observational study was to investigate the occurrence of postoperative delirium (POD) in elderly patients undergoing urological surgery and to identify those factors associated with delirium. Ninety consecutive patients (81 males and 9 females; average age of 74.3 ± 0.40 years), undergoing urological surgery in University-Hospital Urological Clinic were selected. Personal, medical, cognitive and functional data, biochemical parameters, preoperative medications, conduct of surgery and anesthesia and details of hemodynamic control were collected as predictors of delirium. After surgery, the subjects were divided on the basis of delirium onset within a week observation period. …
Spontaneous extrusion of male genital pearling
Pearling is a practice of inserting small beads beneath the skin of the genitalia. Patients generally underwent this practice believing that this would have made their penis bigger and able to better satisfy their partners during intercourse. Pearling can cause complications. We report a case of spontaneous extrusion of genital pearling exiting in a granuloma of the inner face of the foreskin.
Myxoid liposarcoma of the spermatic cord: US and MR imaging findings.
We report a patient with myxoid liposarcoma of the spermatic cord in whom combined use of both ultrasound (US) and MRI helped to suggest the diagnosis. The lesion was solid at US and vascularized at color Doppler. T1-weighted MRI did not show fat within it; on T2-weighted images it had high signal intensity, with a cyst-like appearance. It is known that fat-poor myxoid liposarcomas with high water content may mimic a cystic lesion on non-contrast-enhanced MR; then, a combination of MRI findings, suggesting a cyst, and of US findings, showing the mass was actually solid and vascularized, allowed preoperatively the diagnosis of fat-poor myxoid liposarcoma. © 2013 Wiley Periodicals, Inc.
Monocyte distribution width (MDW) as a reliable biomarker for urosepsis
The use of nephrometry scoring systems can help urologists predict the risk of conversion to radical nephrectomy in patients scheduled for partial nephrectomy
Conversion to radical nephrectomy (RN) in patients scheduled for partial nephrectomy (PN) is an important outcome that should be strongly considered during the decision-making process and adequately discussed with patients during their preoperative counseling. This unplanned event could be due to severe intraoperative complications or oncologic reasons. Intraoperative suspicion of hilar and/or perirenal fat tissue involvement, peritumoral venous involvement, tumor multifocality and/or iatrogenic rupture of the tumor are the most common conditions threatening the oncological safety of the procedure.
Prognostic value of nuclear matrix protein expression in localized prostate cancer.
The aim of the study was to correlate nuclear matrix (NM) protein expression profiles with the risk of PSA progression or death in early prostate cancer (PCa).High-resolution two-dimensional gel electrophoresis (2D-PAGE) was used to identify tumor-associated NM proteins in the PCa specimens obtained from 94 patients. The association between the expression of each protein and the probability of PSA progression or death was studied through univariate analysis. Unsupervised hierarchical clustering analysis was then used to generate patient clusters showing comparable outcomes by including the proteins that were predictive at univariate analysis. PSA-free and overall survival curves relative to…

Finding the right biomarker for renal cell carcinoma (RCC): Nivolumab treatment induces the expression of specific peripheral lymphocyte microRNAs in patients with durable and complete response
Abstract Background The variability of clinical response to immune checkpoint inhibitors in RCC patients makes necessary the discovery of predictive biomarkers for patient selection. Emerging evidence has revealed a multitude of silenced genes and deregulated signalling pathways. These findings point towards extensive microRNAs (miRNAs) regulation and imply epigenetic reprogramming as a key feature of RCC. The aim of this study was to analyze the peripheral lymphocyte miRNA expression profile in metastatic RCC patients undergoing nivolumab treatment, to identify a lymphocyte miRNA signature specifically expressed in patients with partial or complete response (RP; RC) >12 months. Methods miR…
Quality-of-Life Outcomes in Female Patients With Ileal Conduit or Orthotopic Neobladder Urinary Diversion: 6-Month Results of a Multicenter Prospective Study
Radical cystectomy (RC) often affects patients’ life as this surgery is a traumatic and invasive event for the patients, with drawbacks on their daily, social, working, and sex life. Such changes in the quality of life (QoL) of patients are commonly studied through retrospective clinical evaluations and rarely with longitudinal studies. To date, studies focusing on functional outcomes, sexual function, and health-related QoL for female patients are lacking. We evaluated 37 patients using EORTC QLQ-C30 (QLQ-30) and Short-Form 36 (SF-36) questionnaires, before and after surgery, at 3 and 6 months of follow-up. The mean values for the emotional functioning in QLQ-C30 as well as the mental heal…
Ureteral stent encrustation: evaluation of available scores as predictors of a complex surgery
Background: Stent Encrustation is an uncommon event (13%) with a significant impact in patients' management. Aim of our study was to evaluate the available grading systems for encrusted stents. Methods: A retrospective analysis of encrusted stents was performed in four Italian centers between 2006 and 2020. Encrusted stents were classified according to four classifications: the Forgotten Encrusted Calcificated (FECal) score, the Kidney Ureter Bladder (KUB) score, the Visual Grading for Ureteral Encrusted Stent Classification and the Encrustation Burden Score (EBS). Classifications were evaluated to predict complex surgery defined as: long operative time (>60min); need of more than one su…

Can side-specific biopsy findings predict the side of nodal metastasis in clinically localized prostate cancer? Results from a multicenter prospective survey
Background To evaluate the correlation between the side of positive biopsy (Bx) and the risk of lymph-node metastases (LNMs) on each side and to quantify the risk of contralateral LNMs in patients with unilateral positive biopsy. Methods We analyzed the outcomes of 1599 patients with complete data regarding the sides of positive Bx and LN (lymph-node). By dividing each prostate into two separate sides, we assessed the accuracy of the side-specific Bx details in determining the side of positive nodes; the area under the receiver-operating characteristic (ROC) (AUCs) was used. For patients with unilateral positive Bx, we assessed the risk of homolateral and contralateral LNMs according to the…
Pathways for urology patients during the COVID-19 pandemic
The public health emergency caused by the Coronavirus Disease 2019 (COVID-19) pandemic has resulted in a significant reallocation of health resources with a consequent reorganization of the clinical activities also in several urological centers. A panel of Italian urologists has agreed on a set of recommendations on pathways of pre-, intra- and post-operative care for urological patients undergoing urgent procedures or non-deferrable oncological interventions during the COVID-19 pandemic. Simplification of the diagnostic and staging pathway has to be prioritized in order to reduce hospital visits and consequently the risk of contagion. In absence of strict uniform regulations that impose th…

Sexual dysfunction in dialytic patients. A prospective cross-sectional observational study in two hemodialysis centers
Objectives: Incidence and prevalence of patients in dialytic therapy increased considerably in recent years. The onset of new issues, once overshadowed, linked to a lower quality of life like sexual dysfunction became increasingly common. The first study in this area, dating back to the 1970s, shows the high prevalence of sexual dysfunction among patients in dialytic therapy of both sexes. Later studies proved an association of sexual dysfunction with psyche disorders, anxiety, depression and lack of self-confidence. The aim of this study is to describe the incidence of male and female sexual main dysfunctions, the latter not least in literature, in patients in hemodialytic therapy. With th…
Cancer of the Penis
Penile carcinoma is a rare and aggressive disease. Its incidence is related with age over 60 and presence of comorbidities such as HPV infection. The higher incidence rate is reached in developing countries. Penile carcinoma is generally a squamous cell carcinoma and it is frequently foregone by a premalignant lesion. Because of its short time to progression, an early detection is mandatory. Good physical examination is the first step toward a correct diagnosis and staging. CT scan and chest X-ray are useful for nodal stage while US and MRI can provide a preoperative assessment of local invasion. Surgical approach depends on invasion and nodal involvement, varying from a local laser ablatio…
