PURPOSE: Urinary tract infections are relatively common in pediatric patients. Unrecognized bacteriuria at the time of urologic surgery puts patients at increased risk for perioperative complications. Many pediatric urologists obtain preoperative or intraoperative urine cultures prior to surgery, but data are lacking regarding rates and risk factors for positive intraoperative urine cultures. We conducted a retrospective cohort study of patients undergoing pediatric urologic surgery to examine factors associated with positive intraoperative urine cultures...

Invasive candidiasis is a serious pathogen of late-onset sepsis in very-low-birth- weight (VLBW) infants. Kidney is the most common organ involved and it causes morbidity and mortality, especially when fungal balls are formed. We report a 34-day-old female infant (28 weeks, 1152 gm) with systemic fungal infection complicated obstructive uropathy. On sonography, the fungal balls filled the entire pelvis without hydronephrosis. Percutaneous nephrostomy was not feasible. In addition to systemic antifungals, we successfully performed cystoscopy-assisted retrograde ureteral catheterization (RUC) to decompress the pelvis, which also provided a route for local amphotericin B irrigation to achieve therapeutic concentration without nephrotoxicity...

Primary hyperparathyroidism is one of the most common endocrine diseases, however, it is rare in children. In most cases, it is caused by adenoma of these organs. Its most common complications include urolithiasis, nephrocalcinosis and osteoporosis. CASE REPORT: A 16-year-old patient was admitted to our Clinic because of his first-ever renal colic. The ultrasound examination revealed rightsided hydronephrosis caused by the presence of 9 mm stone in the upper part of the right ureter. In addition, the presence of 8 mm stone in the middle calyx of the left kidney was found...

Hydronephrosis in children is most often due to an intrinsic ureteropelvic junction obstruction or by compression on ureter by accessory renal artery coming from the aorta to the lower pole of the kidney. AIM: The aim of study was to present a case with a late onset of hydronephrosis caused by accessory renal artery. CASE REPORT: 5-year old boy with a mild pyelectasia during first 10 months of age was admitted to hospital because of abdominal pain and vomiting. Abdominal ultrasound revealed a marked dilatation of the right pelvicalyceal system with renal pelvis measuring 23 mm in anterior-posterior (ap) diameter, enlargement of calyces to 10 mm and narrowed cortex to 5 mm...

Pyonephrosis in the course of hydronephrosis usually provides to total or near-total loss of renal function. In adults pyonephrosis usually results from urolithiasis. In children usually congenital urinary tract anomalies are present as contributing factors. CASE REPORT: 6-year old girl was admitted to the hospital because of 2-day history of high fever, abdominal pain, progressive deterioration of general condition and ultrasonographically (US) detected left hydronephrosis. US on admission showed grossly dilated left renal collecting system together with extensive echogenic debris and laboratory tests highly elevated inflammatory markers...

BACKGROUND: Post-operative infection after radical cystectomy is a common complication. It is essential to identify modifiable risk factors that can predict post-operative infection to reduce the incidence of infection after radical cystectomy. We investigated the incidence of post-operative infection, associated pathogens, and risk factors for post-operative infection after radical cystectomy. PATIENTS AND METHODS: Patients who underwent radical cystectomy for bladder cancer in a single urologic department from 2014 to 2016 were included...

Obstruction of urine flow at the level of the pelvo-ureteric junction (UPJO) and subsequent development of hydronephrosis is one of the most common congenital renal malformations. UPJO is associated with development of salt-sensitive hypertension, which is set by the obstructed kidney, and with a stimulated renin-angiotensin-aldosterone system (RAAS) in rodent models. This study aimed at investigating the hypothesis that i) in pediatric patients with UPJO the RAAS is activated prior to surgical relief of the obstruction; ii) in rats with UPJO the RAAS activation is reflected by increased abundance of renal aldosterone-stimulated Na+ transporters; and iii) the injured UPJO kidney allows aberrant filtration of plasminogen leading to proteolytic activation of the epithelial sodium channel gamma subunit (γ-ENaC)...

BACKGROUND: Febrile urinary tract infections (UTIs) include a spectrum of pathologies from uncomplicated pyelonephritis to urosepsis, including xanthogranulomatous pyelonephritis (XGP). Most febrile UTIs are treated with antibiotics alone, but studies indicate nearly 12% of cases of presumed simple pyelonephritis require emergent urologic intervention. How to identify these individuals, while limiting unnecessary advanced imaging and delays in diagnosis, challenges all emergency providers...

Although the role of laparoscopic nephrectomy (LN) has been established, few studies have reported cases of LN in individuals with scoliosis. Here we report a case of right LN in a patient with severe right convex scoliosis. A 26-year-old man presented with a fever. His medical history comprised severe right convex lumbar scoliosis. CT revealed right hydronephrosis and right kidney stones. Pyelonephritis requiring nephrectomy was diagnosed. Right LN was feasible with elaborate perioperative care. The postoperative course was uneventful with no relapse of urinary tract infection...

Objective: To examine the relationship between benign prostatic hyperplasia (BPH) and the presence of lower urinary tract stones. Methods: We retrospectively reviewed the records of men with lower urinary tract stones who presented to three clinical centers in Korea over a 4-year period. We divided the patients into two groups based on the location of urinary stones: Group 1 (bladder calculi) and Group 2 (urethral calculi). We compared the characteristics of both groups and performed univariate and multivariate analyses with a logistic regression model to investigate the relationship between BPH and lower urinary tract stones...
