Feasibility and accuracy of prostate cancer risk calculators in prediction of prostate cancer, extraprostatic extension as well as the risk of lymph nodes metastasis.

Introduction: The aim of this article was to evaluate the accuracy of European Randomized study of Screening for Prostate Cancer (ERSPC 4) and Prostate Cancer Prevention Trial (PCPT 2.0) risk calculator on predicting high-grade prostate cancer (HGPCa) and accuracy of Partin and Briganti nomograms on organ confined (OC) or extraprostatic cancer (EXP), seminal vesicles invasion (SVI) and risk of lymph nodes metastasis. Material and methods: A cohort of 269 men aged between 44-84 years, who underwent radical prostatectomy was retrospectively analysed. Based on estimated calculator risk, patients were divided into risk groups: low (LR), medium (MR) and high (HR). Results obtained with calculators were compared to post-surgical final pathology outcome. Results: In ERPSC4, the average risk for HGPC was LR = 5%, MR = 21%, and HR = 64%. In PCPT 2.0, the average risk for HG was: LR - 8%, MR - 14%, and HR - 30%. In the final results, HGPC was observed in: LR = 29%, MR = 67%, and HR = 81%. In Partin, LNI was estimated to occur in: LR = 1%, MR = 2%, and HR = 7.5% and in Briganti: LR = 1.8%, MR = 11.4%, and HR = 44.2% while finally it was found in: LR = 1.3%, MR = 0%, and HR = 11.6%. Conclusions: ERPSC 4 and PCPT 2.0 corresponded well with each other as well as Partin and Briganti. ERPSC 4 was more accurate in predicting HGPC than PCPT 2.0. Partin was more accurate as for LNI than Briganti. In this study group a large underestimation was observed in reference to Gleason grade.

Influence of Antibiotic Administration on the Urinary Bladder Cancer Early Recurrence Rate.

Bladder cancer tends to recur, making treatment one of the most expensive in oncology. The limited efficacy and high cost of adjuvant therapies in the treatment of bladder cancer prompt research on new drugs which could replace them. In vitro studies have established that antibiotics can have a cytostatic and cytotoxic effect on urinary bladder cancer cells. The objective of the study was to investigate the influence of antibiotics on the recurrence rate of bladder cancer. In a retrospective study, we analyzed a group of 199 patients with urinary bladder cancer from four urological centers. The study groups consisted of 40 patients who received ciprofloxacin and 83 patients who received beta-lactams as perioperative antimicrobial prophylaxis. The control group included 76 patients who did not get perioperative antimicrobial prophylaxis. The groups were analyzed for risk stratification, degree of malignancy, and size of the primary tumor. The average follow-up time was 24 months. The main focus of the study was to investigate the early recurrence rate of bladder cancer among studied groups, which could correlate with the effectiveness of currently used intravesical instillations. Additionally, cancer's early progression was examined. Regardless of the division used, the highest recurrence rate was found in the ciprofloxacin group. There were no statistical differences in the recurrence rate between patients who received beta-lactams and patients who did not receive any antibiotics. In addition, there were no differences due to the progression rate between the groups. Perioperative antibiotic administration does not influence the early recurrence rate in patients with nonmuscle invasive urothelial bladder cancer.

Current thromboprophylaxis in urological cancer patients during COVID-19 pandemic.

Introduction: Venous thrombosis is a well-known complication of cancer disease, especially in Urology. However, even though proper antithrombotic prophylaxis is crucial in most urological procedures, we have insufficient high-quality studies on this topic. The European Association of Urology (EAU) Guidelines are outdated and lack data on COVID-19 increased risk of thrombosis. This review aimed to summarize data on thromboprophylaxis after radical prostatectomy, cystectomy, and nephrectomy during COVID-19 pandemic. Material and methods: A thorough analysis of the EAU Guidelines of Thromboprophylaxis was performed and compared to PubMed search, considering updated literature on thromboprophylaxis of radical prostatectomy, cystectomy, nephrectomy, as well as COVID-19 influence on venous thrombosis and urological practice. Results: Each patient should be evaluated individually to balance bleeding and venous thromboembolism (VTE) risk. There is still much uncertainty in low and medium-risk patients and all endoscopic procedures, where thromboprophylaxis could be omitted. Patients with COVID infection bear a significantly higher risk of VTE. All patients should be tested for COVID infection prior to a planned surgery during bursts of infections, undependably of vaccination status. Efforts to maintain early cancer diagnosis and treatment during the pandemic should be maintained. Conclusions: The quality of evidence is inadequate, and when deciding on thromboprophylaxis, we need to base it on individual risk, cancer advancement, procedure type, and our own experience.

Sarcoidosis of the spermatic cord - case report and literature review.

BACKGROUND: Sarcoidosis is a multi-system disease characterized by the formation of non-caseating granulomas in various organs. The lungs remain the most frequently affected organ, whereas lesions in the genitourinary system affect around 0.2% of patients. The primary site found in the spermatic cord is extremely rare. CASE PRESENTATION: We present a patient's case where the spermatic cord involvement was the first manifestation of sarcoidosis. For several months, a number of tests had been performed, which showed, among others, non-caseating granulomas in pathomorphological material, bilateral hilar lymphadenopathy, and leukopenia with lymphopenia. Tumor markers were normal. Infection with urogenital pathogens (including Chlamydia Trachomatis, Neisseria gonorrhea, Mycoplasma hominis) was excluded. The patient did not report any general symptoms such as fever, excessive fatigue, weight loss. He denied swelling, shortness of breath. At the same time, a complete differential diagnosis was carried out, and the extent of the disease was assessed. Due to interdisciplinary management, the patient's quality of life and fertility is preserved. In the discussion, we present the diagnosis, treatment, and prognosis of such patients. CONCLUSION: Sarcoidosis is a multi-system disease, which should not be omitted in the differential diagnosis. Selective excision of the lesion with intraoperative examination plays a significant role while establishing a diagnosis. However, in the primary site in the genitourinary system, the diagnosis is challenging.

RéSUMé: CONTEXTE: La sarcoïdose est une maladie multisystémique caractérisée par la formation de granulomes non caséeux dans divers organes. Les poumons restent l'organe le plus fréquemment touché, alors que les lésions du système génito-urinaire affectent environ 0,2% des patients. La découverte d'un site principal dans le cordon spermatique est extrêmement rare. PRéSENTATION DU CAS: Nous présentons le cas d'un patient où l'atteinte du cordon spermatique a été la première manifestation d'une sarcoïdose. Pendant plusieurs mois, un certain nombre de tests ont été effectués, qui montraient, entre autres, des granulomes non caséeux dans le matériel pathomorphologique, une lymphadénopathie hilaire bilatérale, et une leucopénie avec lymphopénie. Les marqueurs tumoraux étaient normaux. Une infection par des agents pathogènes urogénitaux (y compris Chlamydia Trachomatis, Neisseria gonorrhea, Mycoplasma hominis) a été exclue. Le patient n'a signalé aucun symptôme général tel que fièvre, fatigue excessive, ou perte de poids. Il a nié toute œdème ou essoufflement. Dans le même temps, un diagnostic différentiel complet a été effectué et l'étendue de la maladie a été évaluée. Grâce à la prise en charge interdisciplinaire, la qualité de vie et la fertilité du patient ont été préservées. Dans la discussion, nous présentons le diagnostic, le traitement et le pronostic de ces patients. CONCLUSION: La sarcoïdose est une maladie multisystémique, qui ne doit pas être omise dans le diagnostic différentiel. L'excision sélective de la lésion, avec examen peropératoire, joue un rôle important lors de l'établissement d'un diagnostic. Cependant, en cas de localisation du site primaire dans le système génito-urinaire, le diagnostic est difficile.

Zinner Syndrome-A Rare Cause of Recurrent Epididymitis and Infertility.

Zinner syndrome (ZS) is a rare disorder that affects only men. It is characterized by a triad of abnormalities, including unilateral renal agenesis, ipsilateral seminal vesicle cysts, and atresia of the ejaculatory tract. Unfortunately, there is no consensus on the best treatment modality. We describe a case of a young male patient with recurrent epididymitis, dysuria, and frequent urination. In the diagnostic evaluation, we found an extended right seminal vesicle in the ultrasound with hyperechoic fluid inside and an absence of the right kidney. We performed magnetic resonance imaging, computed tomography, and semen analysis confirming Zinner syndrome and deteriorated semen parameters. Urethroscopic evaluation and ultrasound-guided puncture of the seminal vesicle were performed. An abscess was excluded. The cytologic evaluation showed hemosiderophages. Tamsulosin was introduced. We found no signs of relapse in a six-month observation, and the patient had no further symptoms. Therefore, minimally invasive treatment is a feasible option in young patients found with early-stage Zinner syndrome.

Extent of lymphadenectomy in patients with bladder cancer undergoing radical cystectomy - a multi-institutional analysis.

Lymph node dissection (LND) performed at radical cystectomy (RC) has therapeutic and staging significance. However, the extent of LND remains controversial. The aim of this study was to analyze surgical patterns and results of LND in a contemporary series of patients with bladder cancer. This is a retrospective analysis of 113 consecutive patients subjected to RC in seven urological centres in the year 2013. The mean age of the cohort was 66.6 years. There were 49 cases of organ confined and 64 cases of locally advanced disease. Study endpoints were: status and extent of LND, number of LNs removed, and number of positive LNs. LND was performed in 102 patients (90.3%). Detailed data on the anatomical extent of LND was available in 82 patients (80.4%). Limited (lLND) and extended LND (eLND) was performed in 68.3% (n = 56) and 31.7% (n = 26) of patients, respectively. Obturator fossa LNs were removed in 84.1%, external iliac in 72.0%, internal iliac in 40.2%, common iliac in 31.7%, and presacral in 15.9% of cases. The median number of LNs removed in the whole study cohort, in patients who underwent lLND, and eLND, was 8.5, 5, and 16.5, respectively. In 28 patients (27.5%), LN metastases were diagnosed, including 6 cases (12.5%) in the organ-confined cohort and 22 cases (34.4%) in the locally advanced disease cohort. LND is an integral part of radical cystectomy in patients with bladder cancer. However, in the majority of patients, the extent of the procedure was suboptimal, potentially negatively affecting the survival and adequacy of pathological staging.
