PURPOSE: To examine the incidence, characteristics, and management of patients who had tumor bed recurrence after partial nephrectomy. PATIENTS AND METHODS: We retrospectively reviewed the charts of 2,256 patients with sporadic small renal masses undergoing partial nephrectomy between 2000 and 2014. Local tumor bed recurrence was strictly defined as either: 1) detection of a new enhancing lesion specifically within the surgical defect or 2) detection of a new enhancing lesion within the same region (e...

Solitary functioning kidneys form an important subgroup of congenital anomalies of the kidney and urinary tract (CAKUT). A solitary kidney can be congenital or acquired after unilateral nephrectomy and is often associated with ipsilateral urogenital anomalies. Both types of solitary functioning kidney are associated with an increased risk of chronic kidney disease (CKD). A low functional nephron number results in compensatory glomerular hypertension and enlargement of remnant nephrons, indicating glomerular hyperfiltration...

Metastatic disease involving the thyroid gland is uncommon. Solitary thyroid metastases from various primary sites particularly kidney, lung, and breast had been previously described. To the best of our knowledge, metastases from two topographically separate primary malignancies to the thyroid have never been documented hitherto. This is the first reported case of cancer-to-cancer metastasis involving an invasive breast carcinoma metastasized within a metastatic renal cell carcinoma in the nonneoplastic thyroid in a 58-year-old woman...

Renal artery aneurysms (RAAs) are an uncommon finding but are more often associated with other congenital disorders. The complex (hilar) RAAs constitute a subset of RAAs that present a therapeutic dilemma for the vascular surgeon; because of their anatomic location. This dilemma worsens when hilar RAAs occur with a solitary kidney where organ preservation is vital. Ex-vivo reconstruction with autotransplantation is especially suitable for hilar RAAs, even when they are associated with a solitary kidney. We report two of such cases of RAA's with a solitary kidney in patients with pertinent congenital anomalies...

The purpose of the study was to evaluate the functional and morphological recovery of solitary kidneys following the relief of obstruction by two different approaches. Data of 65 adult patients with acute renal failure in obstructed solitary kidney were evaluated. Depending on the type of emergent decompression procedure while 34 patients were treated with a double J stent placement only 31 patients underwent ureteroscopic lithotripsy with double J stent placement. Following these procedures, in addition to the amount of excreted urine during the first 24 h, changes in the serum creatinine levels and the degree of hydronephrosis were noted and evaluated during the first week of follow-up after intervention...

Following contemporary trends in arterial endovascular therapy of the lower extremities, recent major trials in anti-hypertensive renovascular revascularization have focused on outcomes after primary stenting of the renal artery. Angioplasty-only therapy has not been studied in a major trial since the year 2000. As such, the current study by Saeed et al. presents an updated data set on the technique with one unique aspect: patients underwent post-procedural physiologic scintigraphy to document the effects of unilateral intervention in patients with two kidneys...

Cigarette smoking affects many organs. It causes vasoconstriction through activation of sympathetic nervous system which leads to elevation of blood pressure and reduction in glomerular filtration rate and filtration pressure. It also causes thickening of renal arterioles. Cigarette smoking increases the risk of microalbuminuria and accelerates progression of microalbuminuria to macroalbuminuria. Furthermore, it causes rapid loss of glomerular filtration rate in chronic kidney disease patients. After kidney donation, these factors may be injurious to the solitary kidney...

Renal Artery Stenosis (RAS) is an important cause of treatment-resistant hypertension. Uncontrolled hypertension with RAS can cause progressive chronic kidney disease (CKD) leading to end-stage kidney disease. Therapeutic revascularisation can be helpful in appropriate circumstances where pharmaceutical intervention has failed and significant renovascular disease contributes to resistant hypertension. We present an interesting case of a Caucasian male with peripheral vasculopathy, abdominal aortic aneurysm (AAA), single functioning kidney and ostial RAS caused by stent struts from an endovascular AAA stent graft...

RATIONAL: The inhibition of renin-angiotensin-aldosterone system (RAAS) is a major strategy for slowing the progression of chronic kidney disease (CKD). The utility of anti-RAAS agents in patients with congenital or acquired solitary kidney is still controversial. OBJECTIVE: A systematic literature review was conducted. MAIN FINDINGS: The conclusions of the few available studies on the topic are homogeneously in agreement with a long-term reno-protective activity of anti-RAAS drugs in patients with solitary kidney, especially if patients are hypertensive or proteinuric...

Individuals suffering from chronic kidney disease (CKD) deal with major morbidity and mortality including poor exercise tolerance. A variety of factors including anemia, poor muscle mass, cardiovascular changes and limited physical activity contribute to exercise intolerance. Studies suggest that early initiation of aerobic and resistance training improves the muscle function, ability to tolerate exercise and quality of life in CKD patients. A thorough medical examination and exercise testing are recommended before initiating an exercise regimen in individuals with CKD...

Solitary papilloma is a human papillomavirus (HPV)-induced benign indolent epithelial tumor with limited growth, whereas papillomatosis is an entirely different entity. Papillomatosis requires attention because of its aggressive and recurrent clinical progress with risks of dysplastic and malignant transformation. Recurrent respiratory papillomatosis (RRP) has a high prevalence of dysplasia and reports of transformation to carcinoma-ex-papillomatosis, especially when associated with low-risk HPV type 11. Although papillomatosis seldom occurs in the oral cavity, this report describes 3 cases of oral papillomatosis in immunocompromised patients, with 1 case identified as having HPV type 11...

Laryngeal cancer is the 14th most common malignancy worldwide, and its common subtype squamous cell carcinoma (SCC) is highly associated with tobacco use and long-term alcohol consumption. The incidence of distant metastasis from a primary laryngeal cancer has been reported to be very low, between 6.5% and 8.5%, according to published tumour registry data. Distant metastases of laryngeal SCC most commonly involve the lung, liver, bone and mediastinum, seldom involving the kidney. Renal metastasis has been well established in many other cancers such as lymphoma, lung, breast and gastric carcinoma...

BACKGROUND: The different mechanisms leading to a solitary kidney should be differentiated because the long-term outcome might be different. The fetal period is the best moment to make a true diagnosis of congenital unilateral renal agenesis (URA). The objective was to determine the prevalence of URA at birth. The secondary objectives were to describe the evolution of sensitivity of prenatal diagnosis over time and the different forms of URA (isolated and associated with other malformations) detected up to 1 year...
