A comparative study of electrosurgical vs. cold urethrotomy in the treatment of urethral strictures.

Thirty-one patients with urethral stricture were subjected to internal urethrotomy under visual control. The patients were divided into two groups according to the surgical procedure: electrosurgical or cold resection. A modification of the Sachse knife was introduced in order to permit its use with the American Cystoscope Makers Inc. instruments. The success rate with cold resection was 81.81% and with the electrosurgical procedure 40%. Internal urethrotomy with cold resection is a simple and harmless operation, being a first choice in the treatment of urethral stricture.
