Renal angiomyolipoma is a distinctive benign neoplasm that occurs either sporadically or in patients with tuberous sclerosis complex. A 45-year-old woman was admitted with history offlank pain and vomiting. There were no signs suggestive of tuberous sclerosis either in the patient or her family. At operation, she had a left renal mass with nephrolithiasis and hydronephrosis. Histopathology revealed epithelioid angiomyolipoma of the left kidney with chronic pyelonephritis. Immunohistochemistry confirmed the diagnosis of angiomyolipoma. This case is presented to highlight the epithelioid variant of angiomyolipoma which may behave in an aggressive manner.

The article presents results of retrograde endoscopic pyelolithotripsy (REP) in 75 patients with large and coral nephroliths. Retrograde contact pyelolithotripsy was made with application of Swiss Lithoclast unit, semirigid ureteroscopes R. Wolf with a cone 8-9 Ch and working channel 5.3 Ch. This enables maximal removal of the destroyed concrement by hydraulic litholapaxia with consequent insertion of the internal stent. Extracorporeal lithotripsy with low-energy shock-wave impulses was performed on demand (1-3 sessions). The stent was removed in 3-5 days in cases of complete one-stage sanation of the kidney and in 2-3 weeks in the presence of residual fragments of the nephrolith. One-stage complete sanation in coral nephrolithiasis (K1-K2) up to 5 cm3 and large concrements was achieved in 69.3% patients. Three months later residual fragments of the nephroliths were observed in 8% patients, 6 months later--in 5.3%. One year after treatment a complete sanation was achieved in 96%. Complications of the method consisted in exacerbation of chronic pyelonephritis observed in 12% cases. The control examination revealed improvement of renal function early and late after surgery. As shown by 6-year follow-up, recurrent nephroliths occurred in 6% patients. Endoscopic retrograde pyelolithotripsy can be used as a method of choice in the treatment of compound forms of nephrolithiasis in intrarenal type of the pelvis, the absence of marked extension of the caliceal-pelvic system of the kidney, in other stones resistant to extracorporeal lithotripsy.

Spontaneous renal artery dissection (SRAD) is a rare event, and thus may be a challenge for physicians to diagnose and treat. We report a case of SRAD in a healthy 56-year-old male who presented with flank pain, fever, and elevated white blood cell count. The patient was initially diagnosed with nephrolithiasis versus pyelonephritis and was admitted for observation. Multiple imaging modalities, including non-contrast computed tomography (CT), magnetic resonance imaging (MRI) with gadolinium, CT angiogram, and intraoperative angiogram, were used to make the final diagnosis of SRAD. The patient was treated with endovascular stent placement and is currently free of pain with normal laboratory values and blood pressure.

The ureter which runs behind the main lower vein is the evolutionary fault of the vascular system. It is the result of the disorder of the foetal vein canals developments. The clinical symptoms resulting from this fault are: the pains in the lumbar region, hematuria, the recurrent pyelonephritis, nephrolithiasis and the arterial hypertension. Ultrasonography, tomography and magnetic resonans imaging are used in the diagnosis. The best treatment is the operation leading to the restoration of the ureter anatomic position. Nowadays the laparoscopic minimal invasive methods are used more and more often. In this study we described 3 patients. Each of them underwent the operation to correct the ureter position. The result was the improvement of the clinical condition.

Ovarian vein thrombosis (OVT) is a rare cause of abdominal pain that may mimic a surgical abdomen. The differential diagnosis of OVT includes acute appendicitis, endometritis, pelvic inflammatory disease, pyelonephritis, nephrolithiasis, tubo-ovarian abscess, and ovarian torsion. The complications of OVT, including sepsis and pulmonary embolism, are significant. Diagnosis relies on a careful examination of the radiographic findings. This diagnosis should be considered not only in postpartum patients but also in women with pelvic inflammatory disease, recent abdominal surgery, malignancy, or known hypercoagulable state. In this report we present a case of OVT in a 29-year-old woman presenting with 3 days of sharp left-sided abdominal pain, nausea, and vomiting after bilateral salpingectomy. We then discuss the epidemiology, pathophysiology, and clinical management of OVT.

Two West Indian manatees (Trichechus manatus spp.) were reported with severe emaciation. One animal was a Florida manatee from the Everglades; the other was an Antillean manatee from Cuba. On necropsy, both animals had nephrolithiasis, pyelonephritis, and moderate to severe renomegaly. Histopathology revealed multifocal to diffuse pyelonephritis, interstitial nephritis, and nephrocalcinosis. The stones were analyzed and consisted primarily of calcium carbonate. Serum chemistry values for the Florida animal revealed no renal abnormalities. The mechanism of calculus formation remains unclear in manatees. In horses, another hindgut fermenter, the most common urolith is also calcium carbonate. Urinalyses performed on manatees are very similar to those of horses (i.e., alkaline urine, low specific gravity, and calcium carbonate crystals). Formation of uroliths in manatees may have a pathogenesis similar to equine urolithiasis.

We report a 65-year-old woman with leukemia who presented with urinary tract infection, splenic abscess, and a renal mass. Both urine and pus culture of the splenic abscess yielded Klebsiella pneumoniae. The differential diagnosis of the renal mass by radiological findings included unliquefied renal abscess, xanthogranulomatous pyelonephritis, and renal cell carcinoma. Percutaneous biopsy of the renal mass confirmed the diagnosis of xanthogranulomatous pyelonephritis. Because of high surgical risk, the patient received medical treatment with prolonged antibiotic therapy. With antibiotic therapy only, not only the splenic abscess was cured but also follow-up ultrasonography showed progressive resolution of the renal mass. The occurrence of xanthogranulomatous pyelonephritis has rarely been reported in the absence of urinary tract obstruction or nephrolithiasis. Furthermore, this is the first report of xanthogranulomatous pyelonephritis occurring in patients with leukemia and concurrent with splenic abscess. In addition to describing this unusual case, we provide a short review of xanthogranulomatous pyelonephritis successfully treated with antibiotics only.

TAR syndrome is a congenital malformation syndrome characterized by bilateral absence of the radius and thrombocytopenia. The known urinary anomalies are duplex ureter, dilatation of renal pelvis, horseshoe kidney and functional problems like vesicoureteral reflux and pyelonephritis. In this report of a case with TAR syndrome, a kidney stone and bladder telangiectasia were found coincidentally during the investigation of hematuria. TAR syndrome is discussed in the light of the medical literature. To our knowledge, no case has been reported demonstrating nephrolithiasis and bladder telangiectasia in TAR patients.

A 73-year-old woman with leukemia presented with urinary tract infection, splenic abscess, and a renal mass. Both urine culture and pus culture of the splenic abscess yielded Klebsiella pneumoniae. Percutaneous biopsy of the renal mass confirmed the diagnosis of xanthogranulomatous pyelonephritis. Because of high risk for surgery, the patient received treatment with antibiotic therapy for 2 months. With antibiotic therapy, not only was the splenic abscess cured but follow-up ultrasonography also showed progressive resolution of the renal mass. Xanthogranulomatous pyelonephritis is frequently associated with urinary tract obstruction or nephrolithiasis. In this first report of xanthogranulomatous pyelonephritis in a patient with leukemia and splenic abscess, we provide a short review of xanthogranulomatous pyelonephritis successfully treated with antibiotics only.

Female Sprague-Dawley rats (n = 100; age, 3 wk) were fed diets that included a vitamin premix and either albumin or milk powder. Rats fed the albumin diet gained weight more slowly than did the other group. Between 19 and 28 wk of being fed the albumin diet, 12 rats died of bacterial cystitis and pyelonephritis. In addition, 2 more rats from the same dietary group developed peritonitis after ovariohysterectomy. Examination of the 44 rats fed the albumin diet that completed the 34-wk experiment revealed pyelonephritis in 68%, cystitis in 66%, urolithiasis in 27%, and nephrolithiasis in 5%. Squamous metaplasia of the transitional epithelium was present in all 44 rats, although other epithelia were histologically normal. Vitamin A deficiency was diagnosed after analyses of blood and liver samples. Analysis of the vitamin premix revealed approximately 25% of the expected amount of vitamin A. Because the milk powder contained sufficient vitamin A, deficiency did not occur in rats fed the milk powder diet. The major consequences of vitamin A deficiency in the rats were squamous metaplasia, bacterial infection, and calculus formation within the urinary tract. This report illustrates the importance of careful formulation and storage of vitamin premixes used in experimental diets. Vitamin A deficiency should be considered in rats with decreased weight gain and urinary tract disease even if ocular lesions are not present.
