Obstructing vs. Non-Obstructing Stones in Ureter and Kidney<\/strong><\/h2>\n

Kidney stones that block the flow of urine from the kidney or down the ureter are called obstructive kidney stones. \u00a0Depending on stone size and location the blockage can be complete or partial. \u00a0Non-obstructing stones do not block urine flow but can also cause symptoms that are commonly associated with kidney stones. \u00a0A non-obstructive kidney stone may at some point start moving and become obstructive.<\/p>\n

Obstructive Kidney Stones: What You Need to Know<\/h2>\n

Obstructing stones cause blockage in the urinary system and can be potentially dangerous. Obstructing stones usually, but not always, cause symptoms. \u00a0Obstruction can be complete or partial. Symptoms are typically more severe with complete obstruction but occasionally even patients with large stones and complete obstruction do not have much pain but only some discomfort.<\/p>\n

Most commonly obstructing stones are located in the ureter.\u00a0 Obstructing ureteral stones can also occur at UPJ (uretero-pelvic junction) and in the kidneys.<\/p>\n

Stones can also be partially obstructing or intermittently obstructing. This is likely the explanation for intermittent pain \u2013 the severity of obstruction increases as stone moves and leads to pain. If it moves and becomes less obstructing, pain subsides.<\/p>\n

Obstructing stones can lead to severe infection and renal failure.\u00a0 Stones associated with infection or renal failure require prompt treatment.<\/p>\n

The presence of obstructing stones in both ureters concurrently, although rare, is a urological emergency as it can lead to acute renal failure because of the inability to pass urine. ESWL cannot be performed in patients with an obstructing stone and signs of infection (fever).<\/p>\n

Non-Obstructing Stones:\u00a0Today a Friend Tomorrow a Foe<\/strong><\/h2>\n

Non-obstructing stones are typically not symptomatic, but may occasionally cause infection, pain, renal insufficiency, or blood in urine. These can be treated electively with ESWL, ureteroscopy or PCNL.<\/p>\n

If non-obstructing stones are symptomatic or sufficiently large, they should be treated electively as long-term they are likely to cause symptoms, grow and make it more challenging to break them.<\/p>\n

It is important to remember that non-obstructive kidney stones can move at any time and become ‘obstructive’ at the UPJ or in the ureter. \u00a0If they grow to a large size, they can become obstructive even in the kidney causing partial renal caliceal obstruction.<\/p>\n

Most of non-obstructive stones occur in the kidney but some smaller stones in the ureter can also cause minimal partial obstruction or no significant obstruction at all. This is the most likely explanation for why patients sometimes pass kidney stones without knowing it or without experiencing any pain.<\/p>\n
