title: Incidence and management of dialysis patients with renal calculi.
abstract: OBJECTIVE
  The incidence of renal stones in patients on dialysis, while lower in number compared to the general population because of decreased renal function, is nonetheless a clinical dilemma. We wanted to evaluate the incidence and management of stone disease in patients on hemodialysis.
  
  
  METHODS
  We reviewed the literature from 1966 to the present using Medline. Study inclusion criteria were detection and treatment of stone disease in both hemodialysis and peritoneal dialysis patients.
  
  
  RESULTS
  It is estimated that between 5 and 13% of all dialysis patients will develop symptomatic renal calculi and many more asymptomatic calculi. Many of the stone-forming dialysis patients will have recurring stone disease with one study finding an 83.3% recurrence rate.
  
  
  CONCLUSIONS
  Since dialysis patients have a wide range of urine output, the clinician should be alert to the possibility of stone formation. We recommend yearly ultrasound examinations on all dialysis patients as well as citrate and magnesium supplements with careful follow-up of laboratory results and urine electrolytes. We also recommend careful follow-up of all patients on aluminum-hydroxide phosphate binders as they are predisposed to form Al-Mg-urate stones. For those dialysis patients that form renal calculi, watchful waiting and symptomatic treatment is recommended since almost all patients will spontaneously pass their stones. However, ESWL and other current modalities may be used with no greater morbidity compared to nondialysis cohorts. We also suggest that patients with severe recurring intractable stone disease who are candidates for renal transplantation should be offered bilateral nephrectomies.
