Differentials Urinary Tract Infection Musculoskeletal strain
Nephrolithiasis Harrison’s Internal Medicine, 18thed Definition: presence of stones in the kidney
Nephrolithiasis Harrison’s Internal Medicine, 18thed • Prevalence rates: • Male to female ratio – 3:1 • Types of stones: • Calcium oxalate and calcium phosphate (75 – 85%) • Calcium salts (5 – 10%) • Cystine (uncommon) • Uric acid • Struvite (common and potentially dangerous)
Pathophysiology Imbalance bet. Solubility and precipitation of salts!! Harrison’s Internal Medicine, 18thed Kidneys must conserve water…. … but must also excrete materials that have low solubility
Pathophysiology Supersaturation Dec. in citrate levels dehydration Overexcretion of Caclium, oxalate, phosphate, cystine, or uric acid Harrison’s Internal Medicine, 18thed Insoluble materials
Pathophysiology Crystallization Harrison’s Internal Medicine, 18thed Supersaturation reaches it’s maximum…

Diagnostics/workup European Association of Urology 2008 • Diagnostics • Plain CT Scan - A1 • intravenous pyelography (IVP) – GS acute stone cholic • KUB + US - B2a
Management European Association of Urology 2008 Pain relief
Management European Association of Urology 2008 Pain relief
Management European Association of Urology 2008 • 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%
Management European Association of Urology 2008 • Calcium Channel Blocker (nifedipine) • An increase of 9% in stone-passage rates • Alpha blockers • An increase of 29% in stone-passage rates
Management European Association of Urology 2008 • Indications for Active Stone Removal • Stone diameter >/= 6-7 mm • Stone </= 6-7 mm residing in calyx
Management European Association of Urology 2008 Extracorporeal shock-wave lithotripsy (ESWL)
Management European Association of Urology 2008 • 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
Management European Association of Urology 2008 • Contraindications to ESWL treatment • Pregnancy • Severe skeletal malformations • Severe obesity • Aortic and/or renal artery aneurysms • Uncontrolled blood coagulation • Uncontrolled UTI
Management PercutaneousNephrolithotomy (PCNL)
Management Retrograde intrarenal surgery (RIRS)
Management European Association of Urology 2008 • Retrograde intrarenal surgery (RIRS) • 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
Management European Association of Urology 2008 Open and laparoscopic surgery
Managament European Association of Urology 2008 • Chemolysis by percutaneous irrigation • 10% hemiacidrin • magnesium ammonium phosphate • Carbonate apatite • Brushite • Trihydroxylmethylaminomethan solution • Cystine stones • Uric acid

Management 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.
Prevention 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.
