Treatment of Stress Urinary Incontinence with Marshall-Marchetti-Krantz Operation

The purpose of this study is to investigate the clinical result of Marshall-Mar-chetti-Krantz operation, one of the treatment methods for stress urinary ncontinence.

Authors have analyzed the 66 cases out of 83 stress urinary incontinence patientsin whom Marshall-Marchetti-Krantz operation and 1 year follow-up was performed at UrologyDepartment of Ewha Womans University Hospital from January 1990 to December 1993.

The results were as follows:

1) The patients' age distribution was from 33 to 53 years old (mean age 44.9 years). The average number of deliveries was 3.1 and 29 patients were multipara with more than 4 deliveries.

2) As compared with urinary incontinence grade, Grade I was seen in 22 cases (43.9%),Grade II in 40 rases (42.4%) and Grade III in 4 cases (6.1%). Overall Grade II was most frequent.

3) PUV angle between posterior urethra and bladder base seen by chain cystourethrographywas 154.0°(134-179°) in average and urethral inclination was 23.9°(14-50°)in average.

4) The operation took between 36 to 72 minutes with mean 45.2 minutes. Urethral catheter was placed after the operation for mean 5.0 days (4-8 days) ana hospitalization days weremean 8.3 days (7-15 days).

5) 6 cases (9%) of urinary retention was the only postoperative complication and all of themwere resolved 3-7 days after intermittent catheterization.

6) In the fi11ow-up after 6 months, recurrence was seen on the third month after the operationin 2 cases and on the 12th month in 3 cases which resulted in 92.4% of operation success rate.

Marshall-Marchetti-Krantz method can safely be performed in patients withstress urinary incontinence and further comparative study with otter operation method be needed.
