Hydronephrosis with ureteropelvic junction obstruction.
Medical necessity for the diagnosis and treatment of hydronephrosis with ureteropelvic junction obstruction is established by the presence of symptoms (e.g., flank pain, urinary tract infection), imaging evidence of hydronephrosis, and impaired renal function.The intervention (surgical or otherwise) is medically necessary to alleviate symptoms, prevent further kidney damage, and preserve renal function.
Urologists and nephrologists are primarily responsible for the diagnosis and management of hydronephrosis with ureteropelvic junction obstruction.The clinical responsibility involves performing a comprehensive evaluation, which may include imaging studies (ultrasound, CT scan), to confirm the diagnosis and determine the severity of the obstruction.Treatment options vary depending on the cause and severity, ranging from conservative management (e.g., medication for infection) to surgical intervention (e.g., pyeloplasty).
In simple words: Hydronephrosis with ureteropelvic junction obstruction means the kidney's drainage system is blocked where the kidney meets the tube leading to the bladder. This blockage causes the kidney to swell. If not treated, it can damage the kidney.
Hydronephrosis with ureteropelvic junction obstruction is a condition characterized by the dilation of the renal pelvis and calyces due to blockage at the junction where the renal pelvis meets the ureter. This obstruction can be acquired or congenital and can lead to impaired urine drainage, potentially causing kidney damage if left untreated.The condition is classified under the broader category of obstructive uropathy.
Example 1: A 55-year-old male presents with flank pain and intermittent fever. Imaging studies reveal hydronephrosis of the right kidney due to a stricture at the ureteropelvic junction.The patient undergoes pyeloplasty to correct the obstruction., A 2-year-old child is diagnosed with congenital ureteropelvic junction obstruction causing hydronephrosis.The obstruction is managed surgically with an endoscopic procedure to relieve the blockage., A 70-year-old female with a history of bladder cancer presents with worsening hydronephrosis due to ureteral compression from the tumor.A stent is placed to improve urinary drainage until definitive treatment of the cancer can be performed.
Detailed medical history, physical examination findings, imaging reports (ultrasound, CT scan, or intravenous pyelogram), laboratory results (urinalysis, blood tests), surgical reports (if applicable), and pathology reports (if applicable).
** This code is used to report hydronephrosis specifically related to obstruction at the ureteropelvic junction.Other types of hydronephrosis require different codes (e.g., N13.1, N13.2, N13.3).
