Background On encountering a self-inflicted foreign body in the urinary tract, it is common that emergency physicians only consult the department of urology, and no further evaluations from other specialties are sought. Psychological conditions can also involve people with psychiatric disorders who perform self-harming or sexual practices. Many case reports of foreign bodies have been reported in the literature. However, there is little information regarding which specialties to consult in this situation within the emergency department (ED). Methodology This case series study gathered information on 10 cases from patients who attended the ED from 2005 to 2020 with the diagnosis of genital or lower urinary tract foreign body. Results In total, 10 patients were analyzed with a mean age of 37.3 (SD: ±14.1) years. Of the 10 patients, seven (70%) were males, and three (30%) were females. Overall, four (40%) patients presented with lower urinary tract symptoms (dysuria, tenesmus, hematuria, urinary frequency), five (50%) patients had a significant psychiatric history, and eight (80%) patients admitted having these practices for sexual gratification. Conclusions Foreign bodies in the lower urinary tract pose a significant challenge to ED physicians and urologists because some patients do not admit or do not recall inserting foreign bodies. Patients should be interrogated for mental illness, medication use, and a history of foreign bodies in the urinary tract or genitals during the initial evaluation. There is no consensus or screening method for such patients presenting to the ED. Hence, the use of complementary imaging studies and cystoscopy is fundamental for diagnosis. Further, it is essential to perform a psychiatric evaluation to diagnose or address any underlying psychiatric conditions that could cause this behavior.

Introduction: High-grade adenocarcinoma of the prostate tends to have denser glandular structures and a prominent desmoplastic reaction, which could be detected by magnetic resonance imaging (MRI) with a super-high b-value in diffusion-weighted imaging (DWI) sequence, to differentiate it from low-grade carcinomas.Objective: To evaluate the diagnostic validity of the diffusion sequence with values of b4000 s/mm2 for the diagnosis of high-grade prostate cancer (Gleason score ≥ 7).Materials and methods: It is a retrospective analytical study of male patients who have undergone a prostate biopsy and count with a prostate MRI with a DWI sequence of a super-high b-value (4000 s/mm2).Results: The sensitivity of the diffusion sequence with b4000 s/mm2 values to classify as positive for prostate cancer was 57.14% as compared to biopsy. The specificity of the diffusion sequence with b4000 s/mm2 values classifying patients with prostate carcinoma as negative was 84.62%. The probability that the diffusion sequence with b4000 s/mm2 values classifies patients with prostate cancer was 80%. The probability that the diffusion sequence with b4000 s/mm2 values does not classify patients with prostate cancer was 64.71%. The proportion of patients adequately classified with prostate cancer using the diffusion sequence with b4000 s/mm2 values was 70.37%. Conclusions:The study shows that using the diffusion sequence with values of b4000 s/mm2 is an optimal value that serves as a tool to be able to decant those high-risk carcinomas with those of low risk; however, it is not a definitive method of diagnosis that could replace the performance of a biopsy. Since the study sample was limited, these results cannot be interpreted as reliable for diagnosing high-grade prostate cancer and should encourage future studies on a larger scale population to obtain significant evidence for a noninvasive diagnostic tool with a better cost-benefit for the patient.
