[Intraprostatic embolization of cholesterol crystals]. / Embolización intraprostática de cristales de colesterol.

The cholesterol embolism syndrome (CES) is an unusual disease that carries a high mortality rate. Finding intraprostatic cholesterol crystal embolization as the result of transrectal prostate biopsy in a patient with several risk factors for atherosclerosis, should alert the urologist to the possibility of CES existence.

La Enfermedad por émbolos de colesterol (EEC) es una patología poco conocida pero con una alta mortalidad asociada. La presencia de embolias de cristales de colesterol a nivel intraprostático como hallazgo poco común en las biopsias prostáticas transrectales en un enfermo con factores de riesgo tromboembólico, debe alertarnos sobre la posible existencia de la EEC

[Ambulatory treatment of ureteral lithiasis using shock wave extracorporeal lithotripsy]. / Tratamiento ambulatorio de la litiasis ureteral mediante litotricia extracorpórea por ondas de choque.

Presentation of the results obtained with extracorporeal shock wave lithotripsy (ESWL) applied to 3173 ureteral lithiasis with a Dornier HM-4 equipment. Location of lithiasis was pyeloureteral junction (329), lumbar ureter (1068), sacral ureter (238), iliopelvic ureter (1474) and "lithiasic path" (64). All lithiasis were treated in situ. Treatments were carried out ambulatory with no anaesthesia. Treatment/lithiasis rate was 1.3. Percentage of stone-free patients with ESWL alone was 79.2% after the first session, and reached 86.14% with retreatment. Percentage of success for lithiasis in pyeloureteral junction was 81.8%, 79.7% for lumbar ureter lithiasis, 80.09% sacral lithiasis, 90.10% iliopelvic ureter lithiasis and 79.9% for those in the "lithiasic path". 12.6% lithiasis required post-ESWL auxiliary manoeuvres. Post-ESWL minor complications (pain, vegetations) occurred in 5.6% cases and major complications (obstruction, fever, sepsis) in 2.9%. The factors influencing lithiasis fragmentation were the number of shock waves and the lithiasis duration. Size of lithiasis and presence or absence of ureteral catheter had no influence. These results suggest that ESWL is an effective method for managing ureteral lithiasis.
