Prostate cancer (PCa) is a prevalent male malignancy that originates in the epithelial cells of the prostate. In terms of incidence and mortality of malignant tumors in men, PCa ranks second and fifth globally and first and third among men in Europe and the United States, respectively. These figures have gradually increased in recent years. The primary modalities used to diagnose PCa include prostate-specific antigen (PSA), multiparametric magnetic resonance imaging (mpMRI), and prostate puncture biopsy. Among these techniques, prostate puncture biopsy is considered the gold standard for the diagnosis of PCa; however, this method carries the potential for missed diagnoses. The preoperative evaluation of the patient in this study suggested advanced PCa. However, the initial prostate puncture biopsy was inconsistent with the preoperative diagnosis, and instead of waiting for a repeat puncture of the prostate primary, we performed a biopsy of the rib metastasis, which was later diagnosed as advanced PCa.

Multi-parametric prostate MRI (mpMRI) is crucial for diagnosing, staging, and assessing treatment response in individuals with prostate cancer. Radiologists, through an accurate and standardized interpretation of mpMRI, stratify patients who may benefit from more invasive treatment or exclude patients who may be harmed by overtreatment. The integration of prostate MRI into the diagnostic pathway is anticipated to generate a substantial surge in the demand for high-quality mpMRI, estimated at approximately two million additional prostate MRI scans annually in Europe. In this review we examine the immediate impact on healthcare, particularly focusing on the workload and evolving roles of radiologists and urologists tasked with the interpretation of these reports and consequential decisions regarding prostate biopsies. We investigate important questions that influence how prostate MRI reports are handled. The discussion aims to provide insights into the collaboration needed for effective reporting.

Despite the significant advancements in prostate-specific antigen (PSA) screening and the diverse array of available treatments, prostate cancer (PCa) still significantly contributes to cancer-related illness. The most prevalent sites for metastases are bones, distant lymph nodes, and abdominal organs. Nevertheless, metastasis to the renal and retroperitoneal regions originating from prostate cancer constitutes an exceptionally uncommon clinical occurrence. Metastatic PCa commonly presents with elevated serum PSA levels, a hallmark of its diagnostic profile. However, there are instances where patients exhibit atypical metastatic patterns or maintain normal PSA levels. In the case under consideration, the patient exhibited a periureteral tumor with an indeterminate primary origin, subsequently confirmed to be metastatic prostate cancer. This case underscores the importance of recognizing the varied and sometimes elusive presentations of metastatic PCa. Despite its rarity, the occurrence of renal and retroperitoneal metastasis emphasizes the need for vigilance and a comprehensive understanding of the diverse manifestations of advanced PCa for timely and accurate diagnosis, which is paramount in optimizing patient care and outcomes.

Abiotrophia defectiva is a pathogen of the oral, gastrointestinal, and urinary tracts that can cause significant systemic disease with uniquely negative blood cultures depending on the growth medium. Prior cases note possible seeding from relatively common procedures such as routine dental work and prostate biopsies, however case literature describes prior infectious complications to include infective endocarditis, brain abscess formation, and spondylodiscitis. While prior cases describe some aspects of these presentations, we highlight a case of a 64-year-old male who presented to the emergency department (ED) f5or acute onset of low back pain with fever symptoms four days after an outpatient transrectal ultrasound-guided needle biopsy of the prostate, with a prior dental extraction described four weeks prior to arrival. Findings on initial ED presentation and subsequent hospitalization revealed infective spondylodiscitis, endocarditis, and brain abscess formation. This is the only cases noted in literature with all three infection locations with dual risk factors of dental and prostate procedures prior to symptom onset. This case highlights the multifocal illness that can complicate Abiotrophia defectiva infections, and the importance of thorough ED evaluation and multiservice approach for consultation and treatment.

BACKGROUND: Transperineal prostate biopsy is gradually becoming the standard methodology for diagnosing prostate cancer because of its high accuracy and low risk of infection, but careful preparation is not always highlighted before a transperineal biopsy. we reported two cases of hair embedding during transurethral resection of the prostate following transperineal puncture biopsy with a Bard MC1820 disposable biopsy needle. Histological examination did not find the hair follicle structure required for hair growth. The hair source was suspected to be percutaneously brought in by needle during the biopsya simulated experiment was used to analyze and reconstruct the process of hair embedding in prostate tissue.
CONCLUSIONS: Hair embedding caused by perineal prostate biopsy is a consumable-related adverse event, and skin preparation before a transperineal prostate biopsy is recommended.

BACKGROUND: Immunoglobulin G4-related disease is characterized by swelling of various organs throughout the body and nodules/hypertrophic lesions. However, its cause remains unknown. We report a case of immunoglobulin G4-related disease that was diagnosed based on the histopathological findings of prostate biopsy.
METHODS: A 72-year-old Japanese man had been treated by a nearby doctor for hypertension, but subsequently developed lower urinary tract symptoms and was prescribed an α1 blocker for 1 year. However, the patient was subsequently referred to our department because his symptoms did not improve. Prostate-specific antigen was 1.258 ng/ml; however, the nodule was palpable in the right lobe on digital rectal examination, and magnetic resonance imaging suggested Prostate Imaging and Reporting and Data System category 3. Therefore, transrectal prostate needle biopsy (12 locations) under ultrasound was performed. Histopathological examination revealed no malignant findings, although infiltration of lymphocytes and plasma cells, and partial fibrosis were observed. No remarkable findings of obstructive phlebitis were observed. Immunoglobulin G4-related disease was suspected, and immunoglobulin and immunoglobulin G4 immunostaining was performed. Immunoglobulin G4 positive plasma cells were observed in a wide range, immunoglobulin G4 positive cells were noted at > 10 per high-power field, and the immunoglobulin G4 positive/immunoglobulin G positive cell ratio was > 40%. Serum immunoglobulin G4 levels were high at 1600 mg/dl. Enhanced abdominal computed tomography findings suggested periaortitis. Additionally, multiple lymphadenopathies were observed around the abdominal aorta. The patient was accordingly diagnosed with immunoglobulin G4-related disease definite, diagnosis group (definite). We proposed steroid treatment for periaortic soft tissue lesions and lower urinary tract symptoms; however, the patient was refused treatment. A computed tomography scan 6 months after diagnosis revealed no changes in the soft tissue lesions around the aorta. Follow-up computed tomography examinations will be performed every 6 months.
CONCLUSIONS: If immunoglobulin G4-related disease is suspected and a highly invasive examination is required for histopathological diagnosis, this can be performed by a relatively minimally invasive prostate biopsy for patients with lower urinary tract symptoms. Further evidence is needed to choose an optimal candidate for prostate biopsy for lower urinary tract symptoms patients with suspicion of immunoglobulin G4-related disease. For patients with lower urinary tract symptoms with immunoglobulin G4-related disease or a history, performing a prostate biopsy may avoid unnecessary treatment. However, if steroid therapy is ineffective, surgical treatment should be considered.

Prostate biopsy, a frequently performed procedure, is not harmless. In rare cases, life-threatening complications occur. We document a potential lethal bacterial meningitis after transrectal biopsy. In addition to our overview of all previously documented cases, we highlight the evidence of prevention of infectious complications when performing a prostate biopsy.

Development of bilateral hydronephrosis and ureteric rupture has never been reported in the published literature so far. We describe a case of 51years old gentleman who developed this complication aftertrans-rectal ultrasound guided prostate biopsy. The patient was treated with bilateral double-J stent insertion, intravenous antibiotic therapy and recovered completely. There have been reports of hydronephrosis with or without ureteric rupture in the world literature. The causes reported have been such as malignancy, stones, retroperitoneal fibrosis, iatrogenic manipulation, trauma, degenerative kidney conditions and spontaneous causes. This could lead to development of retroperitoneal urinoma, urosepsis, abscess formation, infection and renal impairment.

Rectal bleeding is a known complication of transrectal ultrasound-guided prostate biopsy. It is usually mild and resolves spontaneously. However, massive life-threatening hemorrhage can also rarely occur in this setting, potentially presenting a therapeutic conundrum. We hereby delineate the case of a patient who experienced severe intermittent lower gastrointestinal bleeding following a transrectal ultrasound-guided prostate biopsy. Traditional tamponade methods failed to control the hemorrhage. Subsequently, an urgent flexible sigmoidoscopy revealed an anterior rectal wall prominence with biopsy punctures as the possible source of bleeding. Endoclip was successfully applied at the bleeding site, achieving permanent hemostasis. The patient had an uneventful recovery and was discharged from the hospital. While the use of endoclipping has been widely reported in gastrointestinal endoscopy, its application remains exceedingly rare in this group of patients. To our knowledge, this case represents only the third report of endoclipping alone to treat massive rectal bleeding follwing a prostate biopsy procedure. In addition, we systematically review published medical literature to evaluate endoscopic techniques aimed at managing this important complication. This article illustrates that endoscopic therapy may present an efficient, noninvasive method to deal with severe post-biopsy rectal hemorrhage. Therefore, prompt consultation with the gastroenterology service should be advocated.

BACKGROUND: Transrectal ultrasonography (TRUS)-guided prostate biopsy is the conventional method of diagnosing prostate cancer. TRUS-guided prostate biopsy can occasionally be associated with severe complications. Here, we report the first case of a prostate abscess with aneurysms and spondylodiscitis as a complication of TRUS-guided prostate biopsy, and we review the relevant literature.
METHODS: A 78-year-old man presented with back pain, sepsis, and prostate abscesses. Twenty days after TRUS-guided prostate biopsy, he was found to have a 20-mm diameter abdominal aortic aneurysm that expanded to 28.2 mm in the space of a week, despite antibiotic therapy. Therefore, he underwent transurethral resection of the prostate to control prostatic abscesses. Although his aneurysm decreased to 23 mm in size after surgery, he continued to experience back pain. He was diagnosed as having pyogenic spondylitis and this was managed using a lumbar corset. Sixty-four days after the prostate biopsy, the aneurysm had re-expanded to 30 mm; therefore, we performed endovascular aneurysm repair (EVAR) using a microcore stent graft 82 days after the biopsy. Four days after the EVAR, the patient developed acute cholecystitis, and he underwent endoscopic retrograde biliary drainage. One hundred and sixty days after the prostate biopsy, all the complications had improved, and he was discharged. A literature review identified a further six cases of spondylodiscitis that had occurred after transrectal ultrasound-guided prostate biopsy.
CONCLUSIONS: We have reported the first case of a complication of TRUS-guided prostate biopsy that involved prostatic abscesses, aneurysms, and spondylodiscitis. Although such complications are uncommon, clinicians should be aware of the potential for such severe complications of this procedure to develop.
