The procedure involves placing a band of sling material using fascia lata directly under the bladder neck, which acts as a physical support to prevent bladder neck and urethral descent during physical activity.       
All patients were evaluated postoperatively by clinical examination, PVRU, Peak flow rate on uroflowmetry and urodynamic assessment. 
Results: Mean patients age was 46.5 years (range 27-68) and mean parity was 6 (range 0-10). Follow up was completed in all 32 patients over a mean follow-up period of 26 months (range 3-38). Overall success rate (completely cured and partially cured) was 84%. De. novo detrusor over activity was observed in 25% patients, while 2 patients underwent undo operation for urinary obstruction.
