Effects of urodynamic studies on diagnosis and treatment of female stress urinary incontinence(report of 20 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the effects of urodynamic studies on diagnosis and treatment of female stress urinary incontinence (SUI). Methods Urodynamic studies including the determination of stress leakage spot pressure were performed in 20 cases of SUI.Of them 6 cases (30%) had detrusor instability.Based on the types of SUI pathogenesis,7 cases were of Type Ⅲ,10 cases of mixed type (Type Ⅲ/Type Ⅱ) and 3 cases of Type Ⅱ.Of the 20 cases,16 underwent operation,including modified Gittes suspension in 12,sling with polyester pieces in 3 and MMK plus posterior vaginal wall repair in 1. Results The 16 operatied patients were followed up for 8～40 months(mean,31 months).The patients undergoing MMK or Sling operation were cured.But 3 patients (1 of Type Ⅲ and 2 of Type Ⅲ/Ⅱ) undergoing modified Gittes suspension had relapse (recurrence rate,25%). Conclusions Urodynamic studies are important to the diagnosis and differential diagnosis of SUI,and are indicative for choice of operation approaches.
