N13.732
Vesicoureteral-reflux with reflux nephropathy with hydroureter, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Vesicoureteral reflux (VUR) is a condition where urine flows backward from the bladder into the ureters and possibly the kidneys. When this reflux causes kidney damage, it’s referred to as reflux nephropathy. The presence of hydroureter — swelling of the ureters due to urine buildup — can compound these issues. Bilateral means both sides are affected, involving both ureters and kidneys. This condition can lead to recurrent urinary tract infections (UTIs), kidney scarring, and potential long-term kidney function impairment.
Causes & Symptoms
Clinical Causes: Congenital malformation of the vesicoureteral junction, leading to improper valve function Genetic predispositions affecting urinary tract development Increased bladder pressure from neuromuscular disorders or obstruction Structural abnormalities in the urinary tract Previous urinary tract infections causing scarring and reflux
Key Symptoms: Recurrent urinary tract infections, especially in children Cloudy or foul-smelling urine Pain or discomfort in the lower abdomen or back Frequent urination or the urge to urinate urgently In some cases, no noticeable symptoms; may be detected during imaging tests
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and imaging studies, including: - Voiding cystourethrogram (VCUG): the standard test to visualize urine flow and detect reflux - Renal ultrasound: assesses kidney size, structure, and presence of hydroureter - Nuclear medicine scans (such as DMSA scan): evaluate kidney scarring and function These tests help confirm the diagnosis, determine the severity, and guide treatment planning.
Treatment Protocols: Management of bilateral vesicoureteral reflux with reflux nephropathy and hydroureter may include: - Antibiotic prophylaxis: used to prevent urinary tract infections - Regular monitoring: imaging to assess kidney health and reflux status - Surgical interventions: - Ureteral reimplantation: repositioning the ureters to prevent reflux - Endoscopic procedures: placement of bulking agents to improve valve function - Addressing underlying causes: managing bladder dysfunction or obstructions The approach depends on the severity of reflux, frequency of infections, and extent of kidney damage.
