Venous Fistula

Iatrogenic complications due to renal biopsy majorly include formation of an arterio-venous fistula, pseudoaneurysm or arterio-ureteral fistula. These complications are observed within a span of few days post biopsy and are rare after few years. We reported a case of  32-year-old renal allograft recipient male presenting 6 years post biopsy of the left kidney with left lumbar region pain who was eventually diagnosed with arterio-venous fistula and pseudoaneurysm involving inferior interlobular branch of left renal artery. Superselective embolization was achieved using coils and high concentration glue and transient placement of a venous occlusion balloon with complete technical and clinical success.

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.

Objectives Studies on the short-, medium and long-term effects of flow guiding stents are still limited. In this case report, we present three-year follow-up of the multilayer flow modulator stent in a 55-year-old patient with Crawford Type 2 thoracoabdominal aortic aneurysm. Methods A 55-year-old male patient with Crawford Type 2 thoracoabdominal aortic aneurysm had applied to our medical center. The aneurysm involved coeliac truncus and superior mesenteric artery and extended to the renal artery ostia. Multilayer flow modulator stent was successfully placed, and follow-up CT (Computed tomography) angiographic examination images recorded intermittently (36 months). Results After three years, it was observed that the left renal artery was thrombosed and the left kidney went to atrophy. Other major vascular branches were observed to be open. During this time, the aneurysm was completely closed with thrombus, but the diameter of the aneurysm continued to increase. Conclusions Multilayer flow modulator stents are safe in complex aortic aneurysms. The device increases the thrombus load in the aortic aneurysm and maintains the flow of the main vascular branches. But re-interventions, dilatation of the aneurysm sac and visceral branch obstructions are still challenging for multilayer flow modulator stents.

The aim of this study was to test the hypothesis that the intrarenal renin-angiotensin system (RAS) modulates glomerular angiotensin II (ANG II) receptors. In one protocol ANG II receptors were measured 7 days after unilateral denervation of the left kidney in rats. There were 50% more receptors in the glomeruli from denervated compared with innervated kidneys (right, 1,037 +/- 108 vs. left, 1,556 +/- 143 fmol/mg; P less than 0.01), which was associated with a 63% reduction (P less than 0.01) in left renal vein renin. The differences in ANG II receptors between the left and right kidneys were no longer present when angiotensin-converting enzyme was inhibited with enalapril or when pharmacological amounts of ANG II (50 ng/min) were infused. In a second protocol, renal cortical renin content was raised in the left kidney by placing a 0.20-mm clip on the left renal artery (two-kidney, one-clip Goldblatt model). At 7 days, glomerular ANG II receptors were reduced by 72.3% in the clipped compared with the contralateral kidneys (right, 1,232 +/- 105 vs. left, 341 +/- 170 fmol/mg; P less than 0.01). The differences in ANG II receptors were no longer present after enalapril treatment. Pharmacological maneuvers that either blocked ANG II formation or increased circulating ANG II resulted in an equal number of ANG II receptors in the right and left kidneys. The data indicate that the intrarenal RAS modulates the density of glomerular ANG II receptors and is a more important receptor modulator than plasma ANG II.

We report a case of renal transplantation using a horseshoe kidney from a living, genetically unrelated donor. The recipient was a 60-year-old man with diabetic nephropathy, and the donor was the 63-year-old wife of the recipient with a horseshoe kidney free of complications. Computed tomography showed two renal arteries and one renal vein on the left side, and the isthmus was perfused by several accessory arteries and veins. To demarcate the boundary of the isthmus, the left renal artery was ligated and cannulated for in situ perfusion. Furthermore, the isthmus was clamped, and the boundary of the isthmus was confirmed. The kidney was divided at the left margin of the perfused boundary. The cut ends of the isthmus were closed by sutures. The left kidney was transplanted into the right iliac fossa of the recipient. Asymptomatic fluid collection occurred on the cut surface at the isthmus of the donor, and this fluid decreased in due course. On the other hand, the recipient experienced no surgical complication or rejection, while maintaining serum creatinine levels of 2.00–2.20 mg/dL over a 22-month follow-up period. Horseshoe kidneys may be used for transplantation in selected cases after a detailed preoperative evaluation.

Objectives. Renal artery stenosis, as main cause of renovascular secondary hypertension, is mainly caused by atherosclerosis of large vessels and is clinically characterized by resistant or malignant hypertension, impacting the kidney function to various degrees. The present article brings into attention the case of a patient which developed renal artery stenosis on the left kidney, the same condition occurring 12 years later on the right kidney. Material and method. Our patient was initially diagnosed at the age of 48 with complete occlusion of the left renal artery, for which left nephrectomy was performed, while the right artery was normal. Twelve years later she presents with renal artery stenosis on the right kidney, which is treat by stent-angioplasty. Results. After surgery, the patient’s evolution was positive, with amelioration of the laboratory values, in parallel to the arterial blood pressure. Discussions. The probability that, in the moment of diagnosis of renal artery stenosis with progressive evolution to occlusion caused by atherosclerosis, the other artery would be normal, both seen by ultrasonography and angiography, while years later to develop stenosis, is minimal. Up to present, the literature holds little evidence of such similar cases. Conclusions. In the particular case of patients that were diagnosed with severe renal artery stenosis of atherosclerotic origin and had only one of the arteries affected, it is necessary to keep a permanent monitoring, justified by the risk of development of the same pathology to the other artery

Renal Hilum

Among the variations of the renal system, abnormalities of structure and position of kidney along with the variations of renal vessels are reported most frequently. However, reports on rotational abnormalities and abnormal positions of renal hilum are scanty. During routine dissection of the posterior abdominal wall, laterally rotated kidneys with laterally facing hila were observed in about 60-year-old male cadaver. On right side, the hilum was more on the anterior surface of the organ and right renal vein was emerging almost from the middle of the anterior surface at the lateral edge of the hilum. However, the hilum of the left kidney was observed along the lateral border of the organ and left renal artery was crossing transversely anterior to the kidney forming a loop to reach the hilum. It was also observed that because of the lateral position of the hilum, the renal vessels and pelvis where passing over the anterior surface of the kidney. Rotational variations and abnormal locations of renal hilum are of importance in surgical procedures like percutaneous nephrectomy. Further clinical and surgical importance of the case is discussed in the paper.DOI: http://dx.doi.org/10.3126/ajms.v6i5.12414 Asian Journal of Medical Sciences Vol.6(5) 2015 82-84

Renal Artery Embolization

Introduction: Renal artery embolization is a minimally invasive X-ray endovascular operation that is used in the treatment of various urological diseases. This operation is of increasing interest due to its ability to occlude not only proximal, but also distal renal vessels with a low risk of complications. Recent developments in endovascular technology make embolization one of the effective and safe methods applicable to stop renal bleeding, preoperative preparation for surgical treatment of renal malignant tumors, and first-line treatment for angiomyolipomas. For a certain category of patients, renal artery embolization is practically no alternative method of treatment. This applies to comorbid patients with kidney tumors and aggravated somatic status, in whom the anesthetic risk makes open or laparoscopic surgical treatment impossible, and embolization can reduce symptoms, improve the quality of life of such patients and prolong the patient's life.Clinical case: we demonstrate the experience of X-ray surgical treatment of cT1aN0M0 left kidney cancer in an 80-year-old patient.Conclusion: Embolization of renal arteries in some cases can be an effective and safe alternative treatment for renal cell carcinoma in somatically burdened patients who cannot perform surgical treatment.

Müllerianosis is a rare benign lesion of the urinary bladder, which is constituted by two or more of the Müllerian-duct-derived tissues. We report a 45-year-old perimenopausal multiparous woman presenting with occasional episodes of dysuria and lower abdominal discomfort of recent duration. Ultrasound examination revealed a well-defined lesion in urinary bladder and the absence of left kidney. Contrast-enhanced CT of the abdomen confirmed the findings. During diagnostic cystoscopy, haemorrhagic polypoidal lesions were noted in the left side of the posterolateral wall and dome of urinary bladder along with the absence of left ureteric orifice. Transurethral resection of the bladder lesions was done and histology examination confirmed the diagnosis of Müllerianosis. She was administered Luteinizing hormone-releasing hormone (LHRH) agonist monthly. At 1 year of follow-up, cystoscopy showed only scar tissue. The case was reported for the rarity of Müllerianosis noted in a patient with unilateral agenesis of kidney, a possible cause of delayed presentation.
