[Extracorporeal shockwave lithotripsy in patients with urinary diversion]

Presentation of a review on nine patients (10 renal units) with urinary by-pass and renoureteral lithiasis who underwent shock wave extracorporeal lithotrity in our hospital. The justification for the by-pass was an infiltrant vesical tumour in 6 patients, myelomeningocele in 2, and vesicourethral trauma in the remaining one. All cases were being treated for a Bricker-type by-pass except the last one (bilateral ureterosigmoidostomy). Outcome of treatment was: absence of residual lithiasis in 6, minimal residues in 1 (2 renal units), failure in 1. The remaining patient suffered anaphylactic shock induced by the latex in the ureteral catheter placed prior to lithotrity which caused the patient's death.
