title: Evaluation of bladder clots using a nonsurgical treatment.
abstract: OBJECTIVE
  To introduce a novel method to successfully evacuate severe clot retention in the bladder.
  
  
  METHODS
  A total of 22 male patients were treated using our method for severe clot retention. The bladder was irrigated with 40,000 U chymotrypsin in 50 mL of 5% sodium bicarbonate using a Foley catheter (20 F-24 F) for 30 minutes. The clots were then easily mobilized and evacuated using continuous saline irrigation and suction with a 60-mL syringe. The procedure was repeated 2-4 times until all the blood clots had been evacuated.
  
  
  RESULTS
  Of the 22 patients, 19 were successfully treated using this method, with clot retention thoroughly resolved.
  
  
  CONCLUSIONS
  The chymotrypsin and sodium bicarbonate irrigation technique is safe, inexpensive, and a successful method to evacuate severe clot retention.
