Introduction: Complications of kidney and ureter trauma are directly in the field of the urologist. If they have a second place in the vital prognosis, a good knowledge of these pathologies is essential.
Methods: A systematic review of the literature was carried out using the Medline database in order to identify the most relevant articles in English and French.
Results: Urinary extravasation in the context of blunt kidney trauma has a good functional prognosis. Impaired function of the traumatized kidney is linked to vascular damage associated with grade IV and V. Non operative management is the treatment of choice with deferred management in the event of septic or painful deterioration. The lesions of the ureter are predominantly iatrogenic. While incomplete lesions can be treated endoscopically, complete lesions (stenosis or wound) require surgery. The most frequent lesions, in the distal ureter are easily treated by ureterovesical reimplantation. Large losses of substance may require ileal replacement.
Conclusion: Blunt kidney trauma causing urinary extravasation, with an excellent prognosis, are treated conservatively. Conversely, lesions of the ureter require in the majority of cases an intervention to restore continuity.

Comparison of two negative pressure ureteral access sheaths combined with day-case flexible ureteroscopy for renal stones randomized trial.
Sci Rep
November 2024
Department of Urology, The Second Hospital of Longyan, Longyan, 364000, Fujian, China.
Article Synopsis
- - The study investigates the safety and effectiveness of intelligent intrarenal pressure control versus traditional methods in treating renal stones under 2 cm, involving 60 patients in a randomized, controlled trial from November 2023 to July 2024.
- - Results showed that the intelligent pressure control group took longer for procedures (average 52.5 minutes) compared to the traditional group (46 minutes), with a lower stone-free rate on the first postoperative day (73.33% vs. 93.33%).
- - Despite similar outcomes in stone clearance after two months and low rates of complications for both methods, the traditional approach resulted in lower overall hospitalization costs compared to the intelligent pressure control method.
Clinical application and efficacy analysis of robot-assisted laparoscopic tumor enucleation combined with tumor aspiration in the treatment of renal hilar angiomyolipoma.

Background: For renal hilar angiomyolipoma, general surgical resection is often quite challenging. The aim of this study is to evaluate the safety and efficacy of an innovative robot-assisted laparoscopic strategy that combines tumor enucleation with tumor aspiration in the treatment of renal hilar angiomyolipoma.
Methods: The clinical data of 38 patients with renal hilar angiomyolipoma who went through robotic tumor enucleation combined with tumor aspiration in the Department of Urology, the Affiliated Hospital of Nanjing University Medical School, from December 2019 to December 2022 were retrospectively analyzed.
The Role of Cardio-Renal Inflammation in Deciding the Fate of the Arteriovenous Fistula in Haemodialysis Therapy.

Vascular access is an indispensable component of haemodialysis therapy for end-stage kidney disease patients. The arteriovenous fistula (AVF) is most common, but importantly, two-year failure rates are greater than fifty percent. AVF failure can occur due to a lack of suitable vascular remodelling, and inappropriate inflammation preventing maturation, or alternatively neointimal hyperplasia and vascular stenosis preventing long-term use.

Objective: To identify risk factors for failure of conservative management (CM) for uncomplicated extraperitoneal bladder injuries (EBI).
Methods: The trauma registry at a single Level 1 trauma center was queried for patients presenting with a blunt EBI between 2004 and 2022. Patients with CM and follow-up through at least 1 postoperative cystogram or catheter removal were included.
