[Suprapubic urinary drainage after surgical correction of stress urinary incontinence using Pereyra's technique].

One hundred patients with diagnoses of stress urinary incontinence underwent Pereyra's revised procedure and suprapubic bladder drainage. Postoperative urinary infection was 12%. The urinary infection rate and the length of suprapubic bladder drainage had an excellent relationship (r = 0.9484). Postoperative normal bladder functions recovery was 7.8 days in average. Length of hospitalization was 5.5 days. All these values were significantly reduced respectively urethral drainage (P < 0.01 for urinary infection; P < 0.05 for bladder function recovery and P < 0.001 for hospitalization rate). We did not have any type of serious complications. We conclude that suprapubic is a simple and safe bladder drainage method that offers also economical advantages.
