What dietary precautions should be taken for gastrointestinal stones?

Gastrointestinal stones (bezoars) are a serious condition that can greatly affect a patient’s health. The points below summarize the main dietary measures doctors usually recommend after surgery so that new stones do not form. Drink plenty of plain water every dayA high fluid intake dilutes the intestinal and urinary contents, lowering the concentration of calcium and oxalate and reducing the risk of recurrent stones. Add black fungus (wood-ear mushroom, Auricularia) to the diet when permittedThis food is rich in minerals and dietary fiber; it is traditionally thought to “soften” and break up debris so that fragments can be swept out...

How is extracorporeal shock wave lithotripsy (ESWL)?

Extracorporeal shock-wave lithotripsy (ESWL) was introduced into clinical practice in the early 1980s. Experience has shown it to be a safe, effective and non-invasive treatment; the majority of upper-urinary-tract stones can be managed in this way. Success depends not only on stone size but also on location, chemical composition and anatomical factors. Stone size: Renal stones < 20 mm in diameter should be considered first-line for ESWL. Stone location: Pelvic stones fragment most readily; upper- and mid-calyceal stones respond better than lower-pole stones. Stone composition: Struvite and calcium-oxalate-dihydrate stones break easily; uric-acid stones can be treated with ESWL combined with... Learn more

Why does lithotripsy hurt or not hurt?

Anesthesia is given during lithotripsy, so pain is usually minimal; however, colicky pain may appear later when stone fragments pass down the ureter. Therefore some discomfort is possible during the whole stone-removal process. Main lithotripsy techniques: Extracorporeal shock-wave lithotripsy (ESWL) Suitable for renal stones ≤ 2 cm Stones are localized by X-ray or ultrasound and fractured with focused high-energy shock waves; the resulting sand-like particles are voided with urine. Ureteroscopic lithotripsy / stone extraction Rigid or flexible scopes (flexible scopes preferred for renal pelvis or calyceal stones) Used for radiolucent or ESWL-resistant stones < 2 cm; the scope is passed...

How long does it take for the stone fragments to pass after extracorporeal shock-wave lithotripsy (ESWL)?

After extracorporeal shock-wave lithotripsy (ESWL), the time needed for stone expulsion depends on the size and hardness of the fragments. In most cases, passage begins only after one day; soft stones may be expelled on the same day. Although ESWL can break the stone into pieces, these pieces are still discrete fragments. They have to be flushed out by drinking plenty of water and urinating frequently. The recommended fluid intake is 2 000–3 000 mL per day. Patients are also advised to walk around so that the fragments can migrate and be expelled more easily. A small portion of the... Learn more

How many days of rest are needed after extracorporeal shock-wave lithotripsy (ESWL)?

Patients should rest for at least three days after extracorporeal shock-wave lithotripsy (ESWL); the exact period is adjusted according to how smoothly the stone fragments pass. The repeated shock waves produce mild trauma to the kidney or ureter, leading to localized edema and sometimes small mucosal tears. This explains the slight abdominal pain or discomfort commonly felt after the procedure. Provided the symptoms are tolerable, no extra intervention is required. Post-ESWL routine Drink plenty of water Perform gentle activity (walking) to help gravel descend Avoid strenuous exercise, which can intensify pain while edema is present Minimum 3-day rest is advised....
