29. European Association of Urology 2008

31.  Diagnostics Plain CT Scan - A1 intravenous pyelography (IVP) – GS acute stone cholic KUB + US - B2a European Association of Urology 2008

32.  Pain relief European Association of Urology 2008

33.  Pain relief European Association of Urology 2008

34.  Spontaneous passage (80%) for stones </= 4mm in diameter  >/= 7mm spontaneous passage is very low  Overall passage rate of ureteral stone is: Proximal ureteral: 25% Mid-ureteral: 45% Distal ureteral: 70% European Association of Urology 2008

35.  Calcium Channel Blocker (nifedipine) An increase of 9% in stone-passage rates  Alpha blockers An increase of 29% in stone-passage rates European Association of Urology 2008

36.  Indications for Active Stone Removal Stone diameter >/= 6-7 mm Stone </= 6-7 mm residing in calyx European Association of Urology 2008

37.  Extracorporeal shock-wave lithotripsy (ESWL) European Association of Urology 2008

38.  ESWL sessions should not exceed 3-5x If not yet treated, a percutaneous method might be considered In case of infected stones or bacteriuria, antibiotic therapy should be given before ESWL and continues at least 4 days after Shorter intervals between treatment sessions are usually acceptable for stones in the ureter A frequency of 1-1.5 Hz is acceptable and optimal European Association of Urology 2008

39.  Contraindications to ESWL treatment Pregnancy Severe skeletal malformations Severe obesity Aortic and/or renal artery aneurysms Uncontrolled blood coagulation Uncontrolled UTI European Association of Urology 2008

40.  Percutaneous Nephrolithotomy (PCNL)

41.  Retrograde intrarenal surgery (RIRS)

42. Antibiotic prophylaxis preoperatively to ensure sterile urine Stone extraction with a basket without endoscopic visualization of the stone should not be performed Nitinol baskets preserve tip deflection of flexible ureterorenoscopes and the tipless design reduces the risk of mucosa injury. They are therefore most suitable for use in flexible URS Stenting following uncomplicated URS is optional URS could become a reliable first-line treatment for lower pole stones </= 1.5cm Can be done when ESWL might be contraindicated European Association of Urology 2008

43. Open and laparoscopic surgery European Association of Urology 2008

44.  Chemolysis by percutaneous irrigation  10% hemiacidrin magnesium ammonium phosphate Carbonate apatite Brushite  Trihydroxylmethyl aminomethan solution Cystine stones Uric acid European Association of Urology 2008

48. Cochrane Studies  Patients with lower pole kidney stones who undergo PCNL have a higher success rate than ESWL whereas RIRS was not significantly different from ESWL. However, ESWL patients spent less time in hospital and the duration of treatment was shorter.

49. Cochrane Studies  In this review only one trial was found that looked at the effect of increase water intake on recurrence and time to recurrence. Increased water intake decreased the chance of recurrence and increased the time to recurrence. Further studies are needed.
