2015-01-01 · Reflux nephropathy (RN), previously called chronic pyelonephritis, is the renal scarring associated with VUR. RN may be congenital (also called primary), a result of abnormal renal development leading to focal renal dysplasia, or acquired, resulting from pyelonephritis-induced renal injury. Clinical features and risk factors for renal failure in patients with reflux nephropathy (RN) as seen in an adult nephrology service are likely to be different than those seen in a pediatric service. There are only a few studies on adults with vesicoureteric reflux (VUR) and RN and data on RN as seen in developing countries is still evolving. Abstract. We have studied the clinical features and course of adults with reflex nephropathy and/or primary vesicoureteric reflux, paying particular attention to the differences between males and females, and the presenting features that influence prognosis. incidence of RN in children or adults is not known.

Incidence of hypertension in adults with reflux nephropathy has been reported to be anywhere between 38–60% [4–9]. A retrospective study reported nearly 60% of patients with VUR had hypertension at presentation; it was significantly associated with the presence of >1 g/day of proteinuria, although the exact number of patients who had both proteinuria and hypertension was not reported [ 5 ].

Vesicoureteral reflux (VUR) is commonly identified in pediatric patients and can be associated with reflux nephropathy (RN), chronic kidney disease (CKD), and rarely end-stage renal disease (ESRD).

These include vesicoureteral reflux, urethral stricture, and stenosis. The most common cause of hydronephrosis in young adults is kidney stones, or renal calculi. In older adults, the most common cause of hydronephrosis is benign prostate hyperplasia (BPH), or intrapelvic neoplasms such as prostate cancer.
