N13.39
Other hydronephrosis
Clinical Classification Guidelines
Medical Intelligence & Overview
Other hydronephrosis, classified under ICD-10 code N13.39, refers to the swelling of one or both kidneys due to the build-up of urine. This condition occurs when urine cannot drain properly from the kidneys to the bladder, leading to enlarged kidneys and potential damage if left untreated. Hydronephrosis can affect kidney function over time and may be caused by various underlying health issues.
Causes & Symptoms
Clinical Causes: Blockages in the urinary tract, such as kidney stones or strictures Tumors or growths obstructing the flow of urine Congenital abnormalities present from birth Narrowing of the ureter (ureteral stricture) Blood clots blocking urine passage Infections causing swelling and swelling of the urinary pathways Enlarged prostate in men, leading to obstruction Pregnancy-induced pressure changes affecting urine flow Previous surgeries or injuries affecting urine drainage
Key Symptoms: Pain or discomfort in the side or back Flank pain that may radiate to the groin or abdomen Hematuria (blood in the urine) Frequent urinary tract infections Pain during urination Reduced urine output or difficulty urinating Nausea or vomiting in severe cases Fever if associated with infection
Diagnostic & Treatment
Diagnosis Path: Ultrasound imaging to visualize kidney swelling and obstruction CT scan for detailed assessment of kidney and urinary tract Intravenous pyelogram (IVP), which uses contrast dye to highlight urinary structures Urinalysis to check for signs of infection or blood Blood tests to evaluate kidney function, such as serum creatinine and blood urea nitrogen (BUN)
Treatment Protocols: Relieving the blockage through surgical procedures or minimally invasive techniques like stenting or nephrostomy Treating infections with appropriate antibiotics Removing kidney stones via lithotripsy or surgical removal Surgical correction of congenital abnormalities Managing underlying conditions such as prostate enlargement Regular monitoring of kidney function and imaging studies to assess resolution
