Optimum uterine filling pressure for outpatient diagnostic hysteroscopy: a double-blind, randomized controlled trial.

This study designed a double-blind, randomized controlled trial to assess whether adequate visibility can be achieved with lower uterine filling pressures using normal saline for diagnostic outpatient hysteroscopy and whether patient discomfort can be reduced. A total of 234 patients were randomized to 40 mmHg (77 patients), 70 mmHg (78 patients) or 100 mmHg (79 patients) of uterine filling pressures. The primary outcome measure was the proportion of procedures where adequate visibility was achieved during diagnostic outpatient hysteroscopy.

See-and-treat outpatient hysteroscopy: an analysis of 1109 examinations.

The aim of this study was to assess the feasibility of diagnostic and therapeutic outpatient hysteroscopy. Data were collected prospectively from 1109 consecutive hysteroscopy examinations. The main outcome measure was success and failure of diagnostic and therapeutic outpatient hysteroscopy examination.
