BACKGROUND: Nephron sparing surgery (NSS) is well established as the standard of care for most surgical small renal tumors when technically feasible. While the majority of sporadic renal tumors are solitary, multifocal tumors have been reported in 5.4% to 25% of patients with tumors smaller than 5cm. We present a video where we approach, through laparoscopy, four tumors on the same kidney. CASE STUDY: Male, 58y, went through a routine abdominal ultrasound which showed a 5cm left kidney nodule...

Recurrent congestive heart failure related to renal artery disease is an important clinical entity that is typically observed in bilateral renal artery stenosis or solitary functioning kidney. However, the relationship between heart failure and unilateral renal artery disease, especially that with total occlusion, remains unclear. We report a successful management by unilateral renal artery total occlusion stenting with an evidence of improvement of left ventricular filling and pulmonary artery pressure in case of a patient suffering from medical therapy resistant recurrent congestive heart failure with preserved ejection fraction...

In the management of patients with chronic kidney diseases (CKD), a low-protein diet usually refers to a diet with protein intake of 0.6 to 0.8 grams per kilogram of body weight per day (g/kg/day) and should include at least 50% high-biologic-value protein. It may be supplemented with essential acids or nitrogen- free ketoanalogues if <0.6 g/kg/d. Low-protein diet can reduce proteinuria especially in non-diabetic CKD patients. In hypoalbuminemic patients it may lead to an increase in serum albumin level...

Renal ischemia/reperfusion (I/R) damage may arise due to nephron sparing surgery in patient with a solitary kidney of restricted renal parenchymas. Apoptosis, inflammation and oxidative stress play a significant role in the expansion of renal dysfunction following renal I/R. The aim of the current investigation was to particularize the potential effect of curcumin against hypoxia induced renal injury. The albino Wistar rats divided into groups and each group contains six rats. They groups are normal control; disease control; curcumin (5 mg/kg per day) and another group orally treated with curcumin (10 mg/kg per day) for two weeks before induction of renal I/R...

: Atherosclerotic renal artery stenosis is an increasingly recognized medical problem especially in elderly patients. It commonly occurs with systemic manifestations including hypertension (HTN), chronic kidney disease (CKD) or atherosclerotic diseases including coronary or peripheral artery disease. Significant renal artery stenosis may result in HTN, ischemic nephropathy, however it is still in debate about the benefit of revascularization. Although several randomized controlled trials including Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) and Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study has failed to reveal a significant benefit of angioplasty, angioplasty with medical therapy is increasingly accepted in some patients with certain clinical conditions...

Surgical removal of the kidney tumor outside the body, (ex vivo renal bench surgery) followed by auto transplantation is an emerging and often done procedure to reconstruct the urinary tract. It possesses immense challenges to both the anesthesiologists and the surgeons. The risks are multiplied if you are performing the surgery on a solitary functioning kidney. Here, we are describing the anesthetic management of 70-year-old male post nephrectomy patient undergoing renal auto transplantation by bench surgery...

We report the rare case of a 54-year-old man with uncontrolled renovascular hypertension, who was found to have an abdominal aortic aneurysm with congenital solitary pelvic kidney and superior mesenteric artery stenosis. A single renal artery branched from aneurysmal aortic bifurcation, and both the renal artery and the superior mesenteric artery (SMA) had severe stenosis at their origins. The aneurysm was repaired with a bifurcated Dacron graft, to which the renal artery was anastomosed. SMA bypass was created between the graft's left limb and the SMA using another Dacron graft...

INTRODUCTION: Solitary fibrous tumor (SFT) of the kidney represents a rare neoplasm, and its malignant potential seems to be scarce. Classically, a radical nephrectomy is regarded as the treatment of choice for this condition. CASE REPORT: We present the case of a 37-year-old male patient who underwent left robotic clampless partial nephrectomy of an SFT of the kidney. Our patient has been followed-up carefully, and at 15-month examination, he is free of recurrence...

The solitary kidney (SK) undergoes adaptive phenomena of hyperfunction and hyperfiltration. These secondary adaptive phenomena can make it more vulnerable to potentially nephrotoxic therapies. Adverse reactions of the kidneys to ciprofloxacin are rare, but sometimes severe. Therefore, our study sought to assess the reactions to ciprofloxacin of patients with solitary kidney (SK) and urinary tract infection (UTI) by means of urinary biomarkers. We studied 19 patients with SK and urinary tract infection (UTI) who had been administered a 7-day treatment with intravenous ciprofloxacin...
