Left Flank Pain

Retroperitoneal lipoma presenting with a nutcracker-like phenomenon is extremely rare. I experienced a case of a 65-year-old man presenting with left flank pain and macrohematuria intermittently for 3 years. Computed tomography revealed a lipoma at the left pedicle of the kidney, 30 mm in diameter, causing a curving of the left renal artery and dilatation of the left renal vein. This patient was treated successfully by retroperitoneoscopic resection of the lipoma. There have been no symptoms for 10 years after the operation.

Introduction. Neuroblastomas arise in the case of intimate association of the tumor with large vessels and internal organs. The early detailed stratification of cancer risk, as well as forecasting possible complications of surgery based on visual diagnostic methods, contribute to the improving the results in this category of patients. Material and methods. The study analyzes the results of the diagnosis and treatment of neuroblastoma of thoracoabdominal localization in 9 children aged from 9 to 55 months. All of them received the treatment according to the NB-2004 protocol. Before surgical intervention, the factors of the surgical risk were estimated from computed tomography with contrast, the number of factors averaged of 5. Results. The inclusion of the left renal artery and aorta into the tumor was revealed intraoperatively in 8 children, the involvement of the left renal vein, the right renal artery, the superior mesenteric artery was found in 7 patients, the right renal vein, the celiac trunk - in 6 cases, and the other large vessels - in a smaller number of cases. Damages of the right renal vein in 2 patients, left renal vein - in 2 children, aorta - in 1 child, inferior vena cava - in 2 observations and celiac trunk in 1 patient was sutured without subsequent complications. After injury and suturing of the inferior vena cava in a 1 patient, there was revealed a parietal thrombus without clinically significant hemodynamic disturbances. In 1 observation, postoperative thrombosis of the left renal artery caused the deterioration of the blood flow requiring nephrectomy. Damage to the pancreas in 1 child was accompanied by a long drainage and the formation of pancreatojejunostomy. The volume of the resection of the tumor amounted on average of 93%. The total number of complications in the early postoperative period accounted for 44%, out of which repeated surgical interventions were required in case of bleeding against the therapy of renal artery thrombosis in 1 patient and focal pancreatic necrosis in the 1 patient. The duration of postoperative follow-up was of 18 months. Overall survival is 100%, the event-free survival rate is of 78%. The continued growth of the tumor was registered in 2 patients in the high-risk group. Discussion. Neoadjuvant chemotherapy contributed to the enhancement of the radicalization of the surgical treatment, leading to a decrease in the size of the primary focus, metastases, and involvement of large vessels and internal organs in the tumor. The radical removal of neuroblastoma is acceptable in the absence of the invasive growth in the walls of large vessels and internal organs, otherwise, the resection should be performed for the purpose of cytoreduction and prevention of organ failure due to tumor compression.

We studied the in vivo luminal and contraluminal uptake of [3H]digoxin in dog kidney using the single-pass multiple indicator dilution method. A bolus tracer of 125I-albumin (plasma reference), creatinine, or L-[14C]glucose [extracellular reference (ecf)] and [3H]digoxin (or [3H]ouabain) was injected into the left renal artery, and timed serial samples were collected from the left renal vein (basolateral uptake) and left and right ureters (luminal uptake). [3H]ouabain was excreted solely by filtration and exhibited saturable and irreversible binding at the basolateral surface. Uptake of [3H]digoxin across the basolateral membrane was large and nonsaturable. Despite urine flow-dependent reabsorption and approximately 20% protein binding, the urine recovery ratio for [3H]-digoxin/glomerular (ecf) marker was 0.97 +/- 0.04 (n = 29), indicating net digoxin secretion. After intravenous infusions of cyclosporin in Cremophor EL (0.5-3.5 microM), the urine recovery ratio decreased in a dose-dependent manner from control values of 1.13 +/- 0.06 (n = 12) to 0.62 +/- 0.03 (n = 14). There was no change in the relative renal vein recovery. Left renal artery infusion of quinidine (37.5 micrograms.min-1.kg-1) decreased the relative urine recovery of [3H]digoxin by 46% (n = 6) but had no effect on postglomerular extraction. Cyclosporin and quinidine are known inhibitors of P-glycoprotein. But digoxin did not compete with [3H]azidopine for binding in rat brush-border membranes or membranes prepared from the multidrug-resistant cell line CHRC5. The exact mechanism for renal digoxin secretion remains to be determined, but our results point to a luminal localization of this secretory system.

Introduction: Pelvi-calyceal system consists of renal pelvis along with major and minor calyces.The minor calyces unite with their neighbors two or three chambers to form the major calyces. The major calyces drain into the infundibula. The renal pelvis is formed from the junction of the infundibula. The common pattern of arrangement of structures at the renal hilum, antero-poteriorly is renal vein, renal artery and pelvis. Objectives: To compare the study of pelvi-calyceal system and relationship of structures at hilum of kidney between Nepalese and North Americans. Methodology: The gross and prosected kidney specimens were studied for pelvi-calyceal system and relationship of structures at hilum of kidney in Anatomy department. In Nepal, the study was undertaken in Gandaki Medical College, Kaski and in USA, it was done in Well-cornel University, New York. Result: Tricalyceal major calyx were found in 63.8% in Nepalese and Bicalyceal were found in 65.6% North Americans which is statistically significant variations. The number of minor calyces and pyramids varying 6 in Nepalese and 9 in North Americans were also statistically significant (p<0.05). The arrangement of structures at hilum of kidney from anterior to posterior(renal vein, artery and pelvis) in Nepalese and North American kidneys was 86.1% and 62.5% respectively whereas the structures arranged as renal artery, vein and pelvis from anterior to posterior was 13.9% and 37.5% . Conclusion: There are significant variations in pelvicalyceal system and relations of structures at hilum of kidneys of Nepalese and North-Americans.

Purpose. To report the effectiveness of left renal artery (LRA) occlusion using Amplatzer Vascular Plug (AVP) II as treatment for a high-flow renal arteriovenous fistula (RAVF) with multiple renal vein aneurysms (RVA) to prevent aneurysm rupture and cardiac decompensation. Case Report. A 59-year-old female suffering from a post-traumatic RAVF presented with tachycardia and increased cardiac output (CO). Doppler ultrasonography and computed tomography (CT) scan revealed a high-flow RAVF with multiple RVAs and unilateral critically reduced kidney function. Appreciating recent interventional therapeutic advances, the patient was treated with endovascular placement of AVP II into the left renal artery (LRA) resulting in complete occlusion of the RAVF to effectively reduce the risk of RVA rupture and cardiac decompensation. No anti-platelet medication was administrated after the occlusion of the LRA. The patient’s physical capacity improved since right heart volume strain was normalized, and CO was reduced. Conclusion. Transbrachial AVP II occlusion of the LRA is effective to occlude high-flow RAVFs to prevent risk of life-threatening RVA rupture. Additional follow-up is warranted to verify long-term effectiveness of this approach.

We sought to determine the role the liver might play in the regulation of anion-cation balance during both stable baseline conditions and acute endotoxemia. Ten pentobarbital sodium-anesthetized dogs were instrumented at laparotomy with ultrasonic flow probes around the left renal artery, portal vein, and hepatic artery, and catheters were inserted into the hepatic vein, portal vein, pulmonary artery, left renal vein, and abdominal aorta. Measurements were obtained from each site at baseline and 30-45 min after the intravenous infusion of endotoxin. The total anion flux across the liver was calculated from the strong-ion difference. At baseline, the liver removed anions from the circulation (-0.34 meq/min). With early endotoxemia, however, the liver switched to the release of anions (0.12 meq/min; P = 0.0046). After endotoxin administration, the gut, which was neutral at baseline, began to take up anions (-0.47 meq/min; P = 0.008). Anion flux across the lung and kidney was unchanged. We conclude that in the dog the liver, which removes anions at baseline, switches to release anions during early endotoxemia and may be a major site of acid production in early sepsis.
