PURPOSE This study aimed to determine the predictors of ipsilateral hydronephrosis after ureteroscopic lithotripsy for ureteral calculi. MATERIALS AND METHODS From January 2010 to December 2014, a total of 204 patients with ureteral calculi who underwent ureteroscopic lithotripsy were reviewed. Patients with lack of clinical data, presence of ureteral rupture, and who underwent simultaneous p...

An 89-year-old male presented with dysuria and oliguria. He had a history of benign prostate hyperplasia and neurogenic bladder under long-term Foley catheter use of 10 years. Recurrent urinary tract infections had occurred since then. The laboratory data showed acute renal failure with a blood urea nitrogen (BUN) of 57 mg/dL, creatinine 3.61 mg/dL (baseline renal function 6 months before admis...

Prenatal and postnatal ultrasonography has dramatically increased the number of infants detected with significant asymptomatic uropathology. We report of a fetus with hydronephrosis and dilated ureter, diagnosed insidentally at 25 week of gestation. On assumption of left sided ureteropelvic junction obstruction, postnatal serial diagnostic investigations including abdominal ultrasonography, voi...

BACKGROUND AND OBJECT The cases with adult hydronephrosis are usually performed either conservative surgery or nephrectomy according to the grade of residual renal function. The residual renal function of adult hydronephrosis are usually suspected with analysis of concentration and/or clearance of the renal urine content after percutaneous nephrostomy. However, percutaneous nephrostomy is invas...

OBJECTIVES Hydronephrosis in patients with bladder cancer is caused by tumour at the ureteral orifice, secondary ureteral tumours, intramural or extravesical tumour infiltration, or compression of the ureter. This study investigated the prognostic impact of hydronephrosis in bladder cancer. METHODS A series of 788 patients were treated with radical cystectomy with curative intent for transiti...

Objective: Congenital hydronephrosis is a common prenatally diagnosed anomaly associated with an incidence of approximately 0.5-1% in newborns. The purpose of this study was to clarify the value of 99 m diethylenetriamine pentaacetic acid (99mTc-DTPA) in the assessment of renal function impairment of pediatric hydronephrosis. Methods: A total of 48 children with unilateral ureteropelvic junctio...

PURPOSE We determined the etiology and prognostic significance of adult onset enuresis with absent daytime incontinence. Adult onset nocturnal enuresis unassociated with daytime incontinence is uncommon and there is a paucity of information about its incidence, significance, evaluation and treatment. We present a retrospective evaluation of this condition based on a database review of more than...

Nitric oxide synthases (NOSs, EC 1.14.13.39) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO is an important cellular signaling molecule that helps to modulate the vascular tone, insulin secretion, airway tone and peristalsis, etc, and NO is involved in angiogenesis and neural development. It may function as a retrograde neurotransmitter. NO is mediate...
