OBJECTIVE:
To compare a 16-French resectoscope with a 22-French resectoscope and a 15-French hysteroscope for the treatment of uterine cavity lesions.
METHODS:
This was a prospective, randomized study of women with endometrial polyps or submucous myomas treated with a 16-French resectoscope, a traditional 22-French resectoscope, or a 15-French hysteroscope. The operating time, volume of distension medium delivered, discharge time, and patient discomfort by visual analog scale were recorded. Data were compared by one-way and two-way analysis of variance as appropriate.
RESULTS:
Four hundred one women were included in the analysis. All four parameters showed lower values in the 16-French resectoscope group (142 women) compared with the 15-French hysteroscope group (132 women; P<.01). The mean operating time was 10.87±2.87 minutes in the 22-French group (127 women), 8.33±2.94 minutes in the 16-French group, and 17.11±6.86 minutes in the 15-French group. The mean volume of distension medium delivered was 1,043±230 mL in the 22-French group, 991±442 mL in the 16-French group, and 1,489±566 mL in the 15-French group. The mean discharge time was 1.99±0.72 hours in the 22-French group, 1.08±0.18 hours in the 16-French group, and 1.89±0.68 hours in the 15-French group. Finally, the mean visual analog scale scores were 2.10±0.97 in the 22-French group, 1.93±1.03 in the 16-French group, and 4.00±1.61 in the 15-French group. An analysis of patients subdivided according to the lesion size (less than 1.5 cm and more than 1.5 cm in diameter) showed similar results.
CONCLUSION:
The new 16-French resectoscope is effective for the “see and treat” approach for both small (less than 1.5 cm diameter) and large (more than 1.5 cm diameter) uterine lesions.
