Sanjay Mhalasakant Khaladkar, Kunaal Mahesh Jain, Rajesh Kuber, Sidappa Gandage
Emphysematous pyelonephritis is a life-threatening severe form of pyelonephritis usually occurring in patients with diabetes mellitus with or without obstructive uropathies in whom there is necrotizing infection leading to the gas production of an unclear mechanism involving the renal parenchyma and the collecting system. Necrotizing fasciitis is characterized by progressive necrosis of fat and fascia due to deep-seated infection of subcutaneous tissue. It has a fulminant course with considerable mortality...

OBJECTIVE: Posterior urethral valve is the most common lower urinary tract obstruction in male children. A high percentage of patients with posterior urethral valve evolve to end-stage renal disease. Previous studies showed that cytokines, chemokines, and components of the renin-angiotensin system contribute to the renal damage in obstructive uropathies. The authors recently found that urine samples from fetuses with posterior urethral valve have increased levels of inflammatory molecules...

OBJECTIVES: To assess the effects of slow-releasing H2 S donor GYY4137 on post-obstructive renal function and injury following unilateral ureteral obstruction (UUO) by using the UUO and reimplantation (UUO-R) model in rats and to elucidate potential mechanisms by using an in vitro model of epithelial-mesenchymal transition (EMT). METHODS: Male Lewis rats underwent UUO at the left ureterovesical junction. From post-obstructive day (POD) 1-13, rats received daily intraperitoneal (IP) injection of phosphate buffered saline (PBS, 1 mL) or GYY4137 (200 μmol/kg/day in 1 mL PBS, IP)...

Two cases of anatomical variations of the thymus are presented with respect to the anatomical relations with the left brachiocephalic vein and found during the necropsy process. Less than 2 days after birth with Noonan Syndrome, when the left brachiocephalic vein was scanning behind the upper thymus horns, there were other adjacent lesions consisting of three supernumerary spleens and three hepatic veins. The second case was an 8-year-old infant with child malpractice who died from urinary sepsis due to obstructive uropathy, in which case the upper lobes of the thymus were fused and formed a ring through which the left brachiocephalic vein passed...

Nephrogenic diabetes insipidus (NDI), a rare cause of polyuria and polydipsia in children, is usually managed with medications and careful monitoring of water intake. We present a child who was incidentally found to have right hydronephrosis secondary to ureteropelvic junction obstruction, and was subsequently also diagnosed with NDI. After being medically managed, he underwent open right pyeloplasty. His polydipsia abated within one month of surgery, and he has done well off of medications since that time...

A 59-year-old man with a medical history of hypertension, gout and obesity presented to the hospital with a chief complaint of worsening scrotal oedema. The patient endorsed associated symptoms of decreased force of stream on urination, stranguria and hesitancy with slight dysuria. Physical exam showed an effaced umbilicus and phallus with a hidden scrotum estimated to be 30×20×30 cm in size. Imaging and lab findings led to a diagnosis of total bladder herniation within an incarcerated right inguinal hernia...

Retroperitoneal fibrosis is an inflammatory process which may cause acute renal failure. In patients who admitted to emergency services with obstructive uropathy, retroperitoneal fibrosis should be considered in the differential diagnosis. We present our ten cases who admitted to emergency department with obstructive acute renal failure related to retroperitoneal fibrosis.

A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral obstructive uropathy caused by enlarged paraureteral bladder diverticula. After the non-functioning right kidney and ureter and the bilateral diverticula were removed, the left ureter was reimplanted in the bladder...

BACKGROUND Plasmacytoid is a rare histological variant of urothelial carcinoma (UC). Since the first reported case of plasmacytoid urothelial carcinoma (PUC), in 1991, only about 100 cases have since been reported, with most cases involving the bladder. Urothelial carcinomas of the upper urinary tract represent only 5% of urothelial cancers. To the best of our knowledge, there has only been 1 reported case of PUC of the ureter. PUC is a highly aggressive disease, with a poor prognosis. We present a rare biopsy-proven case of PUC of the ureter with retroperitoneal metastasis...

Background: Obstructive uropathy is a common public health issue that requires imaging research for providing necessary information. The data is important for determining treatment options, and may influence selective management choices. Objective: The aim of the study is to determine whether magnetic resonance urography or computerized tomography urography is the best imaging modality among patients with suspected obstructive uropathy. Methods: Seventy patients; referred from the emergency department for the evaluation of renal colic or hematuria that highly suggested urinary tract abnormalities, were prospectively enrolled...

RATIONALE: Although rare, cases of renal failure secondary to a uretero-inguinal hernia have been reported. PATIENT CONCERNS: Here, we report a case of left renal failure caused by chronic obstructive uropathy due to a uretero-inguinal hernia combined with contralateral renal pelvic carcinoma. DIAGNOSES: The present case highly indicated that a comprehensive examination is very important when diagnosing an inguinal hernia. In particular, it is necessary to check whether the ureter is involved or not...

We present a case of a premature infant with a presumed obstructive uropathy found to be a megalourethra leading to a perinatal postrenal failure. A megalourethra - an uncommon cause of urethral dilatation - is a congenital, non-obstructive anomaly of the penile erectile tissue. We think that a distal stenosis resulted in dysplasia of the penile tissue and an aspect of a megalourethra. Further diagnostic workup included urinary tract sonograms, a voiding cystourethrogram and MAG3 scintigrafy. Initially the patient was managed with supportive care such as a suprapubic urinary catheter, followed by surgical intervention (Bengt Johanson)...

BACKGROUND: There is a paucity of data on paediatric kidney disease in developing countries such as Malawi. Descriptive research on kidney disease is essential to improving patient outcomes. METHODS: We conducted a cross-sectional study at a tertiary hospital in Malawi from 2012 to 2013. Children under 14 years with proteinuric kidney disease were enrolled from paediatric wards and outpatient clinics at Queen Elizabeth Central Hospital (QECH). Demographic, clinical and laboratory data were collected from patients at enrolment and at 3 months review at which point clinical status and disease outcome were ascertained...

BACKGROUND: Obstructive uropathy is a common problem in urologic practice; temporary relief of obstruction in the upper tract poses a significant challenge. Ultrasound-guided percutaneous nephrostomy (PCN) is an option for upper tract drainage; compared to fluoroscopic guidance, it is readily available, affordable, and not associated with radiation exposure. We present our experience with ultrasound-guided PCN. PATIENTS AND METHODS: We studied all patients who had ultrasound-guided PCN in our center between January 2013 and January 2017...

Xanthogranulomatous pyelonephritis (XGP) is a rare benign condition with unknown aetiology and chronic infection of kidney. Commonly, most cases are related with urinary tract obstruction, nephrolithiasis, infection, diabetes, and/or immune compromise. XGP is associated with destruction of the renal parenchyma and granulomatous inflammation with foamy lipid-laden macrophages resulting from obstructive uropathy. It closely mimics a malignancy, exhibiting local tissue invasion and destruction. Adjacent organs especially duodenum as well as very rarely pancreas or spleen may be involved...
