- Hydronephrosis with renal and ureteral calculous obstruction with infection (N13.6)
Medical Intelligence & Overview
Hydronephrosis with renal and ureteral calculous obstruction, classified under ICD-10 code N13.2, refers to a condition where swelling of the kidney occurs due to a blockage caused by stones (calculi) in the kidney or ureter. This obstruction prevents urine from draining properly, leading to potential kidney damage if left untreated. The condition is often associated with the presence of kidney stones that lodge themselves within the urinary tract, causing a buildup of urine and pressure within the kidney units.
Causes & Symptoms
Clinical Causes: Presence of kidney stones (nephrolithiasis) that migrate and obstruct the urinary pathways Ureteral strictures or narrowing, possibly due to scarring or injury Enlarged prostate in men, which can block urine flow Development of tumors pressing on the ureters or renal pelvis Congenital abnormalities of the urinary tract that predispose to obstruction Urinary tract infections leading to inflammation and swelling that cause secondary blockage
Key Symptoms: Flank pain or discomfort, often severe and episodic Pain radiating to the groin or abdomen Hematuria (blood in the urine) Frequent urge to urinate or difficulty urinating Nausea and vomiting, particularly during episodes of severe pain Reduced or absent urine output in some cases Signs of infection such as fever, chills, or malaise, if infection develops
Diagnostic & Treatment
Diagnosis Path: Diagnosing hydronephrosis with calculous obstruction involves several steps, including:
Treatment Protocols: Treatment options aim to relieve the obstruction, remove stones, and prevent future complications. Approaches include:
