Management of blunt renal trauma on pre-existing diseased kidneys: a cross-sectional study.

Pathological kidney trauma is a special entity. Congenital or acquired lesions may interfere with clinical presentation, radiological imaging, and the therapeutic approach. Objective: Our objective was to determine the clinical, radiological, and therapeutic features of this entity. Materials and methods: The medical records of 37 observations were retrospectively collected from January 1992 to February 2022. All cases were explored by a kidney ultrasound and/or a computed tomography scan, and classified according to the American Association of Surgery of Trauma. Pre-existing renal abnormalities were found in 37 patients among 203 (18.2%). The most common underlying lesion were urolithiasis (37.8%) followed by pyelo-ureteral junction syndrome (32.4%). Surgical abstention was decided in 11 cases, four nephrectomies were performed as a matter of urgency, and seven nephrectomies were performed remotely. The cure of uropathy was performed after an average delay of 3 months. Conclusion: Kidneys with underlying pathology are habitually more susceptible to trauma. Contusions are often benign contrasting with a high nephrectomy rate.

Are Diabetic Patients at Increased Risk for Biochemical Recurrence After Radical Prostatectomy?

Introduction Diabetic patients are at a lower risk for prostate cancer. However, the relationship between diabetes mellitus (DM) and biochemical recurrence (BCR) after radical prostatectomy (RP) is less clear. The goal of our study was to determine diabetes's value as a biochemical recurrence predictor. Materials and methods We conducted a retrospective analysis of 117 patients who had undergone open radical prostatectomy between 1999 and 2021 at our institution. Univariate and multivariate statistical analyses were used to identify factors associated with biochemical recurrence. Results On univariate analysis, factors associated with biochemical recurrence were diabetes (p=0.002), preoperative prostate-specific antigen (PSA) levels (p=0.022), positive digital rectal exam (p=0.035), number of positive biopsy cores (p<0.001), unfavorable intermediate risk group (p=0.014), peri-neural invasion (PNI) on RP specimen (p=0.043), tumor volume (p=0.011), and positive surgical margins (p<0.001). Multivariate analysis showed that factors independently associated with biochemical recurrence were diabetes (p=0.039; OR=2.788), number of positive cores (p=0.016; OR=4.124), and positive surgical margins (p=0.008; OR=3.876). Conclusion A history of diabetes mellitus should be taken into consideration when assessing patients' risk of biochemical recurrence after radical prostatectomy. More research on a larger scale is needed to determine diabetes' value as a biochemical predictor.

An unusual association between renal tuberculosis and urothelial carcinoma of the upper urinary tract; a case report.

The occurrence of urothelial carcinoma and tuberculosis in the same kidney is exceptional. To our knowledge, a few cases have been reported in the literature. Herein, we report a case of an unusual association between renal tuberculosis and urothelial carcinoma of the upper urinary tract in a 61-year-old patient and discuss the diagnosis and treatment difficulties.
