A 3-week-old male infant, born full term without complication, developed septic arthritis of his left shoulder. His joint fluid, blood, and bone marrow were all positive for Escherichia coli. Urinalysis demonstrated pyuria. Urine culture obtained after one dose of ceftriaxone and several doses of nafcillin was negative. Work-up revealed a refluxing, right single ectopic ureter with severe hydroureteronephrosis and a non-functioning ipsilateral kidney. After appropriate management of the musculoskeletal infection, he underwent a right nephroureterectomy. Coliform septic arthritis is exceedingly rare in children, with only a few cases reported. We report the first case of septic arthritis with anomalous genitourinary tract development as the source of bacterial seeding. This report re-emphasizes the need to screen the urinary tract in all cases of pediatric gram-negative sepsis.

Single-system ureteral ectopia (UE) encompasses a spectrum of malformations involving the bladder trigone, ureter, and kidney. The clinical presentation is variable, and both diagnostic and therapeutic problems are common. Reduced renal function in these patients may result from primary dysplasia, obstruction, vesicoureteral reflux, or recurrent infection. Based on our experience of seven patients, suggestions for diagnostic procedures and criteria for renal saving versus nephrectomy are offered. The relationship between ostium localization, renal function, and long-term results was investigated. From 1972 to 1990, five female and two male patients were studied. During the same period, 31 patients with UE and duplex kidneys were seen. Ages ranged from 1 day to 7 years. A ureteric opening into the bladder neck was associated with dilatation of the ureter and renal pelvis. Two patients had vaginal ectopia and severe renal dysplasia. In one, a cyst of the vaginal wall (Gardner's cyst) was detected at birth. A male newborn had multicystic renal dysplasia on the left and ureteric ectopia to the ductus deferens on the right side. To our knowledge, he is the first patient reported with renal function totally dependent on a kidney with severe UE. Follow-up ranged from 4 to 9 years. One patient died in the postoperative period because of renal failure and sepsis. All the others are well and have normal creatinine values. Improvement of renal function was noted after ureteral reimplantation (URI) in patients with bladder-neck ectopia. The numbers of infections were also drastically reduced. Our observations suggest that the combination of ultrasound, cyst urethrography, and cystoscopy will be diagnostic in most patients. A suspicion of UE should be raised in symptomatic patients with apparently solitary kidneys, enuresis ureterica, or atypical obstructive uropathy. Reduced renal function in some patients with ectopia to the bladder neck will improve after URI. This may be of importance in patients with bilateral anomalies and marginal renal function.

A case of retroperitoneal perforation of the appendix presenting with a thigh abscess is described. The patient presented with pyrexia (38 degrees C) and abdominal and right thigh pain. There was tenderness in the right loin. His white blood cell count was 22 x 10(9)/L. An intravenous urogram revealed tapering of the right ureter at the L2/L3 level and suggested an infected obstructive uropathy. The patient failed to respond to drainage and antibiotics, so we performed a computed tomography scan, which showed a retroperitoneal abscess extending to the gluteal region and thigh, with signs of small bowel obstruction. This precipitated surgery. The route of extension of infection was through the sacrosciatic notch, which is considered to be a rare way of spread. The patient made a slow but eventual recovery. The overall mortality of this condition is high, but early recognition of an abdominal source of sepsis with appropriate treatment can improve survival.

The aim of this work was to report some case histories on the usefulness of spiral TC, used for several years both to diagnose renal colic and urinary lithiasis and to study radio lucent stones that are often difficult to be detected with traditional radiology. 13 patients, aged between 31 and 76 (average age: 54.2), were therefore examined. Eight of them had a ureteral colic when examined, while five patients had shown symptoms some days before being hospitalised in our ward. In all cases, ultrasonography showed a significant hydronephrosis, while direct radiography of the urinary tract could not detect any images that could be associated with radio-opaque lithiasis. All patients therefore underwent an abdominal spiral TC with no contrast medium within 24 hours after hospitalisation. The confrontation between the results obtained by ultrasonography and those obtained by spiral TC, showed the usefulness of the former method to detect stones located in the proximal ureter or in its intramural tract, while the latter could detect the lithiasis of the proximal ureter in 3 cases (23%), of the mid ureter in 2 cases (15.3%), and of the distal ureter in 8 cases (61%). The stones had, approximately, a 5 mm diameter in 5 cases. In 6 cases the diameter was between 6 and 10 mm, and more than 1 cm in 2 cases. Both methods proved to be equally accurate in the assessment of the hydronephrosis degree and of the thickness of the renal parenchyma. The therapy was medical in 2 cases and open surgery in 3 cases, while 8 patients were treated with ureterolitholapaxy with a ballistic searcher. The usefulness of TC in the study of urolithiasis nowadays is supported by a large literature which clearly supplies with documentary evidence the high sensitivity and specificity of such a method in diagnosing the presence of urolithiasis in general and above all of ureteric stones. Such a method not only makes an accurate evaluation of the stones location possible, but it can also assess the calculi dimensions and the indirect signs of the functionality of the kidney affected, without having to use the contrast medium. This method needs very limited execution times and allows a diagnostic of possible collateral pathologies. The main disadvantage of spiral TC, if compared to conventional radiology, is that the patient is exposed to a larger quantity of ionizing radiations, although such an inconvenience will be overcome by the new and more technologically advanced machines. According to our experience, though based on a limited number of cases, spiral TC allowed us to get a quick diagnosis of radio-lucent lithiasis, to see the seat and dimensions of the calculi and finally to chose the most effective treatment. We can therefore think of a diagnostic protocol, for ureteral colics with hydronephrosis or complicated by hyperpyrexia or sepsis, with spiral TC in order to have a quick diagnosis and start the most effective therapy in case an ultrasonographic research should not result diriment.

Clarithromycin was administered intravenously to 55 rabbits to evaluate its effect on experimental sepsis caused by multidrug-resistant Pseudomonas aeruginosa. Acute pyelonephritis was induced after ligation of the right ureter and injection of 10(8) CFU of the test isolate per kg of body weight into the renal pelvis. The animals were divided into six groups: group A, controls; group B, rabbits that received one intravenous dose of 80 mg of clarithromycin per kg concomitantly with bacterial challenge; group C, rabbits that received two doses of clarithromycin, the second one of which was given 2 h after the first one; group D, rabbits that received 15 mg of amikacin per kg; group E, rabbits that received one dose of clarithromycin and amikacin; and group F, rabbits that received two doses of clarithromycin and amikacin. Serum endotoxin levels were estimated by the QCL-1000 Limulus amoebocyte lysate assay, tumor necrosis factor alpha (TNF-alpha) levels were measured by a bioassay, and malondialdehyde (MDA) levels were measured by the thiobarbiturate assay. Viable bacterial counts in various tissue samples were also assessed. The mean survival times of the animals in groups A, B, C, D, E, and F were 4.50, 7.69, 4.07, 4.55, 11.55, and 11.60 days, respectively (P = 0.033 for group D versus group F, P = 0.006 for group D versus group E, P = not significant for group B versus group E, P = 0.042 for group C versus group F). Serum endotoxin levels were similar between groups at all sampling times; TNF-alpha and MDA levels in groups B, C, E, and F decreased significantly over follow-up. The numbers of viable bacterial cells in the infected kidney were similar among the groups; those in the liver, spleen, lungs, and mesenteral lymph nodes were significantly decreased in groups B, E, and F compared to those in groups A and D. It is concluded that a prolongation of survival in animals with experimental sepsis caused by multidrug-resistant P. aeruginosa was achieved after coadministration of clarithromycin and amikacin and that the increased survival was probably attributable to the immunomodulatory properties of clarithromycin.

The maintenance of depletion of antibody (Ab) reactive with Galalpha1-3Gal (Gal) on pig vascular endothelial cells by the intravenous (i.v.) infusion of a synthetic Gal conjugate has been proposed as a means of delaying Ab-mediated rejection of transplanted pig organs in primates. We have therefore studied the effect of the continuous i.v. infusion of bovine serum albumin conjugated to multiple synthetic Gal type 6 oligosaccharides (BSA-Gal) on anti-Gal Ab levels and on graft survival in baboons undergoing pig kidney transplantation. Group 1 baboons (n=3) underwent extracorporeal immunoadsorption of anti-Gal Ab, a cyclophosphamide (CPP)-based immunosuppressive regimen, and a non-transgenic pig kidney transplant. Group 2 (n=2) were treated identically to Group 1 but, in addition, received a continuous i.v. infusion of BSA-Gal. Group 3 (n=2) were treated identically to Group 2, but without CPP. A single baboon (Group 4) underwent extracorporeal immunoadsorption, a CPP-based regimen, and continuous i.v. BSA-Gal therapy for 28 days, but did not receive a pig kidney transplant. Two of the transplanted pig kidneys in Group 1 were excised on post transplant days 7 and 13 for a rejected ureter, and disseminated intravascular coagulation (DIC), respectively. The third baboon died of sepsis on day 6. All transplanted ureters and kidneys showed some histopathologic features of acute humoral xenograft rejection. Group 2 baboons were euthanized on days 8 and 11, respectively, for liver failure. At autopsy, there were histopathological features of widespread liver necrosis, but the pig kidneys and ureters showed no features of rejection. The pig kidneys in Group 3 baboons were excised for renal vein thrombosis (day 9) and DIC (day 12); there was no histological signs of rejection in the pig kidneys or ureter, although there were focal areas of modest liver injury in one baboon on biopsy. The single Group 4 baboon showed no biochemical or histological features of liver injury. Anti-Gal Ab levels returned in Group 1, but were maintained at negligible levels in the baboons in Groups 2 to 4 that received BSA-Gal therapy. Continuous i.v. therapy with BSA-Gal is largely successful in maintaining depletion of circulating anti-Gal antibodies and in preventing or delaying Ab deposition and acute humoral xenograft rejection in porcine grafts, but may be associated with liver injury when administered in the presence of a pig kidney transplant and CPP therapy. The mechanism of the hepatic injury remains uncertain.

A 59-year-old female was referred to our institute for urinary tract infection with septicemia, thrombocytopenia, and hyperglycemia. Plain abdominal X-ray and computed tomography (CT) showed emphysema at the left renal parenchyma and urinary tract along with the perirenal inflammatory changes. These findings suggested emphysematous pyelonephritis in the early phase of occurrence in a diabetic patient. Transurethral catheterization of the left ureter was immediately performed, and occluded cloudy urine was drained. Ureteral stent was left indwelt transurethrally for easy accession in case of occlusion. E. coli was cultured in drained urine. Administration of antibiotics, insulin, and anti-coagulant was performed, and drained urine became clear in several hours. General condition and laboratory findings were improved normally in a week, and CT did not reveal the emphysematous change of the left renal unit at the 11th hospital day.

To assess the efficacy of clarithromycin as an immunomodulator in experimental sepsis with Escherichia coli, acute pyelonephritis was induced after ligation of the right ureter and injection of the test isolate into the renal pelvis in 40 rabbits. Four groups of treatment were applied with administration of therapy on advent of sepsis-associated pulmonary oedema, as follows: A: controls; B: clarithromycin; C: amikacin, D: both agents. Survival was recorded along with estimation of serum levels of endotoxins (LPS), of tumour necrosis factor-alpha (TNFalpha), malondialdehyde (MDA) and of bacterial counts. Mean survival of groups A, B, C and D was 2.51, 7.60, 10.25 and 11.40 days, respectively. Serum levels of TNFalpha and of MDA of group A increased over-time. Pulmonary oedema at 6 h after bacterial challenge was accompanied by increase of TNFalpha and MDA; administration of clarithromycin decreased their values. It is concluded that intravenous clarithromycin might constitute a promising immunomodulatory agent for the management of sepsis since its efficacy was proved after administration on presentation of sepsis-associated pulmonary oedema. The presented findings emphasise the need for further clinical research of the use of clarithromycin for the therapy of Gram-negative sepsis.

Ureteral injury is a rare but potential serious complication that can occur during a variety of general surgical procedures. Knowledge of the course of the ureter is the first step toward preventing ureteral injuries. While some injuries are noticed intraoperatively, most are missed and present later with pain, sepsis, urinary drainage or renal loss. The choice of treatment is based on the location, type and extend of ureteral injury. For injuries recognized during open surgery, when involving the distal 5 cm of the ureter, an antireflux ureterocystostomy such as the Politano-Leadbetter procedure or a vesicopsoas hitch can be performed. For the middle ureter, an ureteroureterostomy is satisfactory and for the proximal ureter, most injuries can be managed by transureteroureterostomy. In complex situations intestinal interposition, autotransplantation or even nephrectomy can be considered. The majority of patients with delayed diagnosed ureteral injuries should be managed by an initial endo-urologic approach.

We report a case of acute respiratory distress syndrome caused by uropathogenic Escherichia coli induced sepsis and treated successfully. A 56-year-old women admitted for high-fever, dyspnea, and disturbance of consciousness on September 11, 2006, was found in chest computed tomography (CT) on admission to have diffuse infiltration with bilateral pleural effusion. Abdominal CT on admission showed left hydronephrosis complicated with ureteral stones. Because of severe hypoxemia, mechanical ventilation was started from hospital day 1. She went into shock soon after admission. Under mechanical ventilation, she was administered several antibiotics and dopamine. Because sera endotoxins were elevated, she was treated by endotoxin adsorption therapy on hospital day 3. A urethral stent was indwelled in the ureter for drainage after endotoxin adsorption therapy. Because Escherichia coli was isolated from urine and blood cultures, she was diagnosed with acute respiratory distress syndrome (ARDS) caused by E. coli inducing septic shock. After therapy, her condition improved, and she was extubated on hospital day 9. Extracorporeal shock wave lithotripsy was conducted on hospital day 19 and she was discharged.
