GUIDELINE STATEMENTS

Imaging, Pre-operative Testing

1. Clinicians should obtain a non-contrast CT scan on patients prior to performing PCNL.

(Strong, C)
322859

2. Clinicians may obtain a non-contrast CT scan to help select the best candidate for SWL versus URS.

(Conditional, C)
322859

3. Clinicians may obtain a functional imaging study (DTPA or MAG‐3) if clinically significant loss of renal function in the involved kidney or kidneys is suspected.

(Conditional, C)
322859

4. Clinicians are required to obtain a urinalysis prior to intervention. In patients with clinical or laboratory signs of infection, urine culture should be obtained.

(Strong, B)
322859

5. Clinicians should obtain a CBC and platelet count on patients undergoing procedures where there is a significant risk of hemorrhage or for patients with symptoms suggesting anemia, thrombocytopenia or infection; serum electrolytes and creatinine should be obtained if there is suspicion of reduced renal function.

(Expert Opinion, )
322859

6. In patients with complex stones or anatomy, clinicians may obtain additional contrast imaging if further definition of the collecting system and the ureteral anatomy is needed.

All Patients with Renal or Ureteral Stones

23. When residual fragments are present, clinicians should offer patients endoscopic procedures to render the patients stone-free, especially if infection stones are suspected.

(Moderate, C)
322859

24. Stone material should be sent for analysis.

(Clinical Principle, )
322859

26. Open/laparoscopic/robotic surgery should not be offered as first-line therapy to most patients with stones. Exceptions include rare cases of anatomic abnormalities, with large or complex stones, or those requiring concomitant reconstruction.

(Strong, C)
322859

36. A safety guide wire should be used for most endoscopic procedures.

(Expert Opinion, )
322859

37. Antimicrobial prophylaxis should be administered prior to stone intervention and is based primarily on prior urine culture results, the local antibiogram, and in consultation with the current Best Practice Policy Statement on Urologic Surgery Antibiotic Prophylaxis.

(Clinical Principle, )
322859

38. Clinicians should abort stone removal procedures, establish appropriate drainage, continue antibiotic therapy, and obtain a urine culture if purulent urine is encountered during endoscopic intervention.

(Strong, C)
322859

41. If initial SWL fails, clinicians should offer endoscopic therapy as the next treatment option.

(Moderate, C)
322859

42. Clinicians should use URS as first-line therapy in most patients who require stone intervention in the setting of uncorrected bleeding diatheses or who require continuous anticoagulation/antiplatelet therapy.

(Strong, C)
322859

46. In pediatric patients with uncomplicated ureteral stones ≤10 mm, clinicians should offer observation with or without MET using α-blockers.

(Moderate, B)
322859

47. Clinicians should offer URS or SWL for pediatric patients with ureteral stones who are unlikely to pass the stones or who failed observation and/or MET, based on patient-specific anatomy and body habitus.

(Strong, B)
322859

48. Clinicians should obtain a low-dose CT scan on pediatric patients prior to performing PCNL.

(Strong, C)
322859

49. In pediatric patients with ureteral stones, clinicians should not routinely place a stent prior to URS.

(Expert Opinion, )
322859

50. In pediatric patients with a total renal stone burden ≤20mm, clinicians may offer SWL or URS as first-line therapy.

(Moderate, C)
322859

51. In pediatric patients with a total renal stone burden >20mm, both PCNL and SWL are acceptable treatment options. If SWL is utilized, clinicians should place an internalized ureteral stent or nephrostomy tube.

(Expert Opinion, )
322859

52. In pediatric patients, except in cases of coexisting anatomic abnormalities, clinicians should not routinely perform open/laparoscopic/robotic surgery for upper tract stones.

(Expert Opinion, )
322859

53. In pediatric patients with asymptomatic and non-obstructing renal stones, clinicians may utilize active surveillance with periodic ultrasonography.

(Expert Opinion, )
322859

54. In pregnant patients, the clinician should coordinate pharmacological and surgical intervention with the obstetrician.

(Clinical Principle, )
322859

55. In pregnant patients with ureteral stones and well controlled symptoms, clinicians should offer observation as first-line therapy.

(Strong, B)
322859

56. In pregnant patients with ureteral stones, clinicians may offer URS to patients who fail observation. Ureteral stent and nephrostomy tube are alternative options, with frequent stent or tube changes usually being necessary.
