Pyonephrosis
ICD-10 N13.6 is a billable code used to indicate a diagnosis of pyonephrosis.
Pyonephrosis is a serious condition characterized by the presence of pus in the renal pelvis due to infection, often resulting from obstructive uropathy. It typically arises from untreated or inadequately treated pyelonephritis, where bacteria invade the renal parenchyma, leading to inflammation and subsequent necrosis. The condition can also be associated with hydronephrosis, where urine accumulates in the kidney due to obstruction, creating an environment conducive to infection. Patients may present with fever, flank pain, and signs of systemic infection. Diagnosis is often confirmed through imaging studies such as ultrasound or CT scans, which reveal dilated renal collecting systems and possibly the presence of abscesses. Management typically involves antibiotic therapy tailored to the causative organism, along with interventions to relieve any obstruction, such as ureteral stenting or nephrostomy. Failure to address pyonephrosis can lead to severe complications, including renal failure and sepsis.
Detailed notes on imaging results, surgical interventions, and antibiotic therapy.
Management of obstructive uropathy leading to pyonephrosis, post-operative complications.
Ensure clarity on the cause of obstruction and any surgical procedures performed.
Comprehensive records of antibiotic therapy, culture results, and response to treatment.
Patients with recurrent urinary tract infections leading to pyonephrosis.
Document the rationale for antibiotic choice and any resistance patterns.
Performed to relieve obstruction in cases of pyonephrosis.
Document indication for nephrostomy and imaging findings.
Urology specialists should ensure detailed operative notes.
The primary cause of pyonephrosis is typically an obstructive uropathy leading to a urinary tract infection that progresses to pus accumulation in the renal pelvis.
