Hydronephrosis with ureteral stricture, not elsewhere classified
ICD-10 N13.1 is a billable code used to indicate a diagnosis of hydronephrosis with ureteral stricture, not elsewhere classified.
Hydronephrosis with ureteral stricture refers to the dilation of the renal pelvis and calyces due to obstruction of urine flow, typically caused by a stricture in the ureter. This condition can lead to increased pressure within the renal system, potentially resulting in kidney damage if not addressed promptly. The obstruction may arise from various etiologies, including congenital anomalies, tumors, or inflammatory processes. Patients may present with flank pain, hematuria, or urinary tract infections (UTIs). The condition can also be associated with pyelonephritis, which is an infection of the kidney that can occur due to stagnant urine. Interstitial nephritis may develop as a secondary complication due to prolonged obstruction and resultant renal ischemia. Drug-induced nephropathy can also be a concern, particularly if nephrotoxic medications are used in the presence of hydronephrosis. Management often involves addressing the underlying cause of the stricture, which may include surgical intervention, and antibiotic therapy for any associated infections.
Detailed imaging reports, surgical notes, and pathology results.
Patients presenting with flank pain, recurrent UTIs, or renal failure due to obstruction.
Ensure clear documentation of the stricture's location and cause, as well as any interventions performed.
Comprehensive renal function tests, history of drug use, and infection workup.
Patients with chronic kidney disease exacerbated by hydronephrosis or recurrent pyelonephritis.
Document the impact of hydronephrosis on renal function and any nephrotoxic medications used.
Used in cases of hydronephrosis due to ureteral stricture.
Operative report detailing the procedure and indication.
Urology specialists should ensure clear documentation of the stricture's characteristics.
The primary cause can vary but often includes congenital anomalies, tumors, or inflammatory processes that lead to obstruction of urine flow.
