Introduction:
Burch colposuspension is still estimated as a ‘gold standard’ by the Cochrane Collaboration Group in the treatment of operative stress urinary incontinence (SUI) Some urogynecologists agree with this statement, some argue that Burch colposuspension should no longer be used.

Objective:
The aim of this study was to evaluate mid-term effects and patient’s satisfaction with standardized modified colposuspension performed in one centre.

Material and Methods:
Modified colposuspension was performed after standardization by 2 trained gynaecologists in 354 women. Data collected from 227 women were added to the final analysis of mid-term results. Average time from the operation to mid-term visit was 19 months (range 9–36 months).

Results:
At mid-term visit, 86.3% of patients were cured. There was no case of post-void urine residual over 100 ml. Pain near the operated region was reported by 1 woman from agricultural region. No one reported negative impact of modified colposuspension on sexual activity or dyspareunia.

Conclusions:
Modified colposuspension according to the E. Petri technique seems to be an operation that is safe and well-tolerated by women with preoperative stress urinary incontinence and paravaginal defect without urodynamic signs of ISD in mid-term observation.
