Renal artery pseudoaneurysm after blunt renal trauma is an uncommon complication of delayed hemorrhage, and diagnostic difficulties are experienced due to its rarity. Delayed hemorrhage after renal trauma is a life-threatening complication. Angiography is considered the gold standard to diagnose a traumatic renal artery pseudoaneurysm. We report here a case of delayed bleeding from a renal artery pseudoaneurysm that was diagnosed at 17 days after the injury and that was managed successfully with selective renal artery embolization without medical complication.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.

Acute renal failure is a well known serious complication following open heart surgery and is associated with a significant increase in morbidity and mortality rate. From 1984 to 1990, 33 patients who had acute renal failure following cardiopulmonary bypass received renal replacement therapy. PD[Peritonial dialysis] was employed in 11 patients and CAVH[continous arteriovenous hemofiltration] was employed in 22 patients. Their age ranged from 3 months to 64 years[mean 25.5$\pm$7.8 years]. The disease entities included congenital cardiac anomaly in 18, valvular heart disease in 15 and aorta disease in 2 cases. Low cardiac output was thought as a primary cause of ARF except two redo valve cases who showed severe Aemolysis k depressed renal function preoperatively. Mean serum BUN and creatinine level at the onset renal replacement therapy were 65$\pm$8 mg/dl and 3.5$\pm$0.4 mg/dl respectively, declining only after reaching peak level 7&10 days following the onset of therapy. Overall hospital mortality was 72.7%[24/33]; 81%[9/11] in PD group and 68.2% [15/22] in CAVH group respectively. The primary cause of death was low cardiac output & hemodynamic depression in all the cases. The fatal complications included multiorgan failure in 7, disseminated intravascular coagulation and sepsis in 6, neurologic damage in 4 and mediastinitis in 3 cases. No measurable differences were observed between CAVH and PD group upon consequence of acute renal failure and disease per se. The age at operation, BUN/Cr level at the onset of bypass and highest BUN/Cr level and the consequence of low output status were regarded as important risk factors, determining outcome of ARF and success of renal replacement therapy. Thus, we concluded that althoght the prognosis is largely determined by severity of low cardiac output status and other organ complication, early institution of renal replacement therapy with other intensive supportive measures could improve salvage rate in established ARF patients following CPB.

Trauma is an important risk factor for a pulmonary thromboembolism, and anticoagulation is essential to prevent deep vein thrombosis (DVT) in patients with trauma. Low-molecular-weight heparin (LMWH) is excreted in the kidney; therefore, using LMWH in patients with renal insufficiency may increase the risk of bleeding complication. The following case describes a 55-year-old traffic accident victim who had massive bleeding and underwent a laparotomy for bleeding control. The patient had acute renal failure, and enoxaparin was administered for the prophylaxis of DVT. Although the patient suffered from serious complications such as pericardial hematoma, the patient recovered without sequellae and was discharged at day 84.

The conclusions which was acquired one renal cell carcinoma and renal disease 132 cases that was tested renal echogram among 4,499 cases for recent 16 months at medical department, Dae Han Kyoyuk Insurance company from August, 1984 to November, 1985 are as follows: 1. On bur ultrasonography, the echo of tumor was demonstrated with echogenicity as compared with renal parenchyme. 2. The case was stage I by Robson's modification method for pathologic histology. 3. There is no fever, typical triad of renal cell carcinoma and the result of serum biochemical test was within normal limit. 4. The frequency with disease was renal cell carcinoma(0.76%), ureteral stone(1.5%), multicystic kidney(2.27%), hydroureter(2.27%), Bilateral poly cystic kidney(4.55%), hydronephrosis(4.55%), renal agenesis(6.06%) renal calculi(18.18%), simple cyst(60.61%). 5. The frequency with age was 55/1200 case(4.58%) in $41{\sim}50$ years, 13/296 cases(4.39%) in $51{\sim}60$ years, 43/2144 cases(2.01%) in $31{\sim}40$ years, 14/791 cases(1.77%) in $21{\sim}30$ years, 7/53 cases(1.32%) more than 61 years and 0/15(0%) under 20 years. 6. The affected site of renal agenesis 8 cases was right side all. 7. In total renal disease 132 cases, the affected site of 126 cases except bilateral polycystic kidney 6 cases was right kidney 72 cases, left kidney the proportion of right to left 1.6:1 8. In total renal disease 132 cases except bilateral polycystic kidneys 6 cases, the patients affected with both side kidneys were 14 cases. 9. The affection rate with sex in total renal disease 132 cases was 98/2860 cases in male, 34/1819 cases in female and the former was about 2 times than the latter. 10. Classifying the stone with part, nephrolithiasis 24 cases were appeared high frequency, on the contray, ureteral stone 2 cases. 11. 2 cases of ureteral stone developed complication, hydronephrosis and hydroureter. 12. The linear array type transducer was not helpful for the diagnosis of lower ureteral calculi but for the lower ureteral calculi, we could see the stone with high echo in accompanying with acoustic shadowing. 13. In 24 cases of renal calculi, both side nephrolithiasis was 3 cases(12.5%). 14. In renal calculi, solitary stone could be seen extremely much and the number of stone was so much variable from 2 to 10. 15. In 26 cases with renal calculi and ureteral stone, the common clinical manifestation was a intermittent and slight pain. 16. In 80 cases of renal cyst, as one's get older, the affection rate of cyst extremely rised. 17. In bilateral polycystic kidney, large cyst had septum on the whole. 18. The patients with complication were 14 cases(10.6%) of total patients.

The most common anatomic variant seen in donor kidneys for renal transplantation is the presence of multiple renal arteries, which can cause an increased risk of complications. Accessory renal arteries should be anastomosed to the proper source arteries to improve renal perfusion via the appropriate vascular reconstruction techniques. In microsurgery, 2 kinds of vascular augmentation methods, known as 'supercharging' and 'turbocharging,' have been introduced to ensure vascular perfusion in the transferred flap. Supercharging uses a distant source of the vessels, while turbocharging uses vascular sources within the same flap territory. These technical concepts can also be applied in renal transplantation, and in this report, we describe 2 patients who underwent procedures using supercharging and turbocharging. In one case, the ipsilateral deep inferior epigastric artery was transposed to the accessory renal artery (supercharging), and in the other case, the accessory renal artery was anastomosed to the corresponding main renal artery with a vascular graft (turbocharging). The transplanted kidneys showed good perfusion and proper function. No cases of renal failure, hypertension, rejection, or urologic complications were observed. These microsurgical techniques can be safely utilized for renal transplantation with donor kidneys that have multiple arteries with a lower complication rate and better outcome.

Purpose: Blunt injury accounts for 80-95% of renal injury trauma in the United States. The majority of blunt renal injuries are low grade and 80-85% of these injuries can be managed conservatively. However, there is a debate on the management of patients with high-grade renal injury. We reviewed our experience of renal trauma at our trauma center to assess management strategy for high-grade blunt renal injury. Methods: We reviewed blunt renal injury cases admitted at a single trauma center between August 2007 and December 2015. Computed tomography (CT) scan was used to diagnose renal injuries and high-grade (according to the American Association for the Surgery of Trauma [AAST] organ injury scale III-V) renal injury patients were included in the analysis. Results: During the eight-year study period, there were 62 AAST grade III-V patients. 5 cases underwent nephrectomy and 57 underwent non-operative management (NOM). There was no difference in outcome between the operative group and the NOM group. In the NOM group, 24 cases underwent angioembolization with a 91% success rate. The Incidence of urological complications correlated with increasing grade. Conclusions: Conservative management of high-grade blunt renal injury was considered preferable to operative management, with an increased renal salvage rate. However, high-grade injuries have higher complication rates, and therefore, close observation is recommended after conservative management.

Envenoming by Russells viper causes a broad spectrum of renal impairment. Renal failure is an important complication in patients bitten by Russells viper. Experimental work in animals and in vitro has elucidated pathophysiological mechanisms that contribute to life threatening complications and have suggested possibilities for therapeutic intervention. The evidence in experimental animals regarding mechanisms of venom action in relation to changes in either extrarenal or intrarenal factors is presented. The cardiovascular system and renal hemodynamics are affected by venom. Reductions of renal function including renal hemodynamics are associated directly with changes in general circulation during envenomation. Possible endogenous mechanisms for releasing the hormone inducing renal vasoconstriction after envenomation are evident. Hormonal factor such as the catecholamine, prostaglandin and renin angiotensin systems induce these changes. Direct nephrotoxicity of venom action is studied in the isolated per-fused kidney. Characteristic polarization of the cell membrane, changes of mitochondrial activity and Na-K ATPase in renal tubular cells are observed. Changes in renal function and the cardiovascular system are observed of ter envenomation and are reversed by the administration of Russells viper antivenom (purified equine immunoglobulin, $Fab_2$ fragment). The neutralizing effects are more efficient when the intravenous injection of antivenom is given within 30 min after the envenomation.
