Summary
A pseudoaneurysm caused gross hematuria after kidney cancer surgery. Selective angioembolization successfully treated the condition, with no recurrence observed for 28 months.
Area of Science:
- Urology
- Vascular Surgery
- Radiology
Background:
- Retroperitoneoscopic partial nephrectomy is a standard procedure for renal cell carcinoma.
- Postoperative complications, though rare, require prompt diagnosis and management.
- Pseudoaneurysms can arise after renal surgery, leading to significant bleeding.
Observation:
- A 59-year-old woman developed gross hematuria 16 days post-retroperitoneoscopic partial nephrectomy.
- Doppler ultrasonography identified a pseudoaneurysm as the source of bleeding.
- The patient presented with significant, visible blood in her urine.
Findings:
- Selective angioembolization was performed to treat the renal pseudoaneurysm.
- The procedure effectively stopped the hematuria.
- No pseudoaneurysm recurrence was noted during a 28-month follow-up period.
Implications:
- Early diagnosis of post-nephrectomy pseudoaneurysms is crucial for successful management.
- Angioembolization is a safe and effective treatment for post-surgical renal pseudoaneurysms.
- This case highlights the importance of vigilant monitoring for vascular complications after minimally invasive renal surgery.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:18Blood and Nerve Supply to the Kidney
The kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...
