title: Sphincterotomy and micturition parameters: quantitative analysis of sphincterotomy in 24 patients.
abstract: The effect of transurethral external sphincterotomy, performed in 24 patients, was evaluated quantitatively on micturition parameters and blood loss. The total urethral resistance, residual urine, and the maximum and average urinary flow rates were all improved with a statistically significant difference (p less than 0.01). Of 7 patients with indwelling catheter, all but one became catheter free. Erythrocytes and hemoglobin decreased 6% in number and 9% in weight, respectively. Moderate degree of stress incontinence were noted in 15 patients (63%).
