Urethral obstruction due to retained bullets migrating into the genitourinary system has rarely been reported. The literature describes two main methods of retained bullet removal from the genitourinary system: (1) spontaneous expulsion during voiding and (2) manual extraction due to urethral obstruction causing acute urinary retention. We present a case in which a 21-year-old man presented with acute urinary retention three years after suffering a gunshot wound to the abdomen. A retained bullet eroded through the bladder wall, migrated through the bladder and urethra, and eventually became lodged in the external urethral meatus, causing obstruction and urinary retention.
To evaluate the impact of cisplatin-based neoadjuvant chemotherapy (NAC) in patients who underwent nephroureterectomy for high grade (HG) upper tract urothelial carcinoma (UTUC).
Is Extraprostatic Extension of Cancer Predictable? A Review of Predictive Tools and an External Validation based on a Large and a Single Center Cohort of Prostate Cancer Patients
Our aim was to review and externally validate all the available predictive tools (PTs) predicting EPE using the area under the curve (AUC), calibration plots and scaled brier score.A literature search was performed showing 19 models predicting EPE. External validation (EV) was carried out on 6360 prostate cancer (PCa) patients submitted to RP. Most of the PTs showed poor discrimination and unsatisfactory calibration.The majority of the available PTs are not reliable for the prediction of EPE in populations other than the development one; thus, they may not be completely appropriate for patients’ counselling or for surgical strategy preplanning.
Location of recurrence by Gallium-68 PSMA-11 PET scan in prostate cancer patients eligible for salvage radiotherapy
To identify locations of recurrence after radical prostatectomy (RP) with PSA <2 by Gallium-68 Prostate Specific Membrane Antigen (PSMA)-11 PET imaging, and to determine whether standard nodal radiation fields would cover the location of prostate cancer recurrence.
