Pyonephrosis;hydronephrosis with infection, including obstruction or stricture with infection.
Medical necessity for the diagnosis and treatment of pyonephrosis is established by the presence of clinical symptoms and findings consistent with a kidney infection with or without obstruction, confirmed by diagnostic testing.Treatment is necessary to prevent serious complications such as sepsis, kidney damage, or loss of renal function.
Diagnosis and management of pyonephrosis typically involves a urologist.This includes evaluating the patient's symptoms, conducting imaging studies (ultrasound, CT scan), identifying the causative organism through urine culture, and managing the infection with antibiotics.In cases of obstruction, procedures such as nephrostomy or ureteral stenting might be necessary.

In simple words: Pyonephrosis means there's pus in your kidney because of an infection, often caused by a blockage stopping urine from draining properly.This blockage could be from a kidney stone or other problems.
Pyonephrosis is a medical condition characterized by the presence of pus within the kidney, typically resulting from a kidney infection (pyelonephritis) often complicated by urinary tract obstruction.This condition encompasses hydronephrosis (swelling of the kidney due to urine backup) accompanied by infection.The obstruction may be caused by various factors, including kidney stones, strictures, or crossing vessels.Additional codes (B95-B97) may be used to specify the infectious agent.
Example 1: A 65-year-old male presents with fever, flank pain, and elevated white blood cell count.Imaging reveals hydronephrosis of the right kidney with a large staghorn calculus obstructing the ureter.Urine culture confirms E. coli infection.The diagnosis is pyonephrosis (N13.6) due to calculus obstruction (N13.2).Appropriate antibiotic therapy is initiated., A 30-year-old female with a history of vesicoureteral reflux experiences recurrent urinary tract infections.Imaging demonstrates hydronephrosis with scarring of the left kidney and evidence of infection.Diagnosis: Pyonephrosis (N13.6) secondary to reflux nephropathy.Treatment includes antibiotics and potentially surgical intervention to address the reflux., A 70-year-old male with prostate cancer undergoing radiation therapy develops pyelonephritis and hydronephrosis.Cystoscopy reveals a tumor obstructing the ureter.The diagnosis is pyonephrosis (N13.6) secondary to malignancy.Management includes antibiotics, palliative measures to relieve obstruction, and consideration of further cancer treatment.
Complete history and physical examination;detailed description of symptoms (fever, flank pain, dysuria, etc.); results of urinalysis (including culture and sensitivity); imaging studies (ultrasound, CT scan, or IVP) showing hydronephrosis and any obstruction;laboratory results (CBC, blood cultures); documentation of any interventions (e.g., nephrostomy, antibiotic treatment).
** The diagnosis of pyonephrosis necessitates a high index of suspicion given its serious implications.Prompt diagnosis and treatment are critical to prevent severe complications.
