Discharge Instructions for Kidney Stone in Ureter

Pain Management

  • The American Urological Association recommends NSAIDs (diclofenac, ibuprofen, metamizole) as first-line analgesics for renal colic due to their superior efficacy and fewer side effects compared to opioids 2
  • The guideline suggests using the lowest effective dose of NSAIDs to minimize cardiovascular and gastrointestinal risks 2
  • Opioids should be used as second-line therapy only when NSAIDs are contraindicated or insufficient for pain control, as recommended by the medical community 2
  • Pain medications should be taken on a regular schedule rather than "as needed" for optimal pain control, according to medical guidelines 2

Medical Expulsive Therapy (MET)

  • Alpha-blockers (tamsulosin, terazosin, doxazosin) should be prescribed for stones <10mm to facilitate spontaneous passage, as suggested by The Journal of Urology 3, 4
  • Medical Expulsive Therapy can increase stone passage rates by 29% and reduce stone passage time, according to medical research 2
  • Patients must be informed that alpha-blockers are used "off-label" for this purpose and counseled about potential side effects, as recommended by The Journal of Urology 1
  • Most stones that will pass spontaneously do so within approximately 17 days (range 6-29 days), based on medical studies 5

Follow-up Instructions

  • Schedule periodic imaging (preferably low-dose CT or ultrasound) to monitor stone position and assess for hydronephrosis, as recommended by The Journal of Urology 1, 5
  • Complete metabolic testing if indicated (first-time stone formers should have stone analysis performed), according to medical guidelines 6
  • Follow up with a urologist within 2-4 weeks if the stone has not passed, as suggested by medical research 5

Return to Medical Care Immediately If:

  • Uncontrolled pain develops despite adequate analgesia, according to medical guidelines 5
  • Fever, chills, or other signs of infection develop, as recommended by The Journal of Urology 1, 6
  • Development of obstruction or worsening hydronephrosis occurs, based on medical research 5
  • Anuria (complete cessation of urine output) develops, according to medical guidelines 2

Treatment Options if Stone Fails to Pass

  • Both shock wave lithotripsy (SWL) and ureteroscopy (URS) are acceptable first-line treatments, as recommended by The Journal of Urology 1
  • URS yields significantly greater stone-free rates for most stones but has slightly higher complication rates, according to medical research 1
  • SWL is less invasive but may require additional procedures, based on medical studies 3, 4
  • Blind basketing (stone extraction without endoscopic visualization) should never be performed, as recommended by The Journal of Urology 1
