Incidence of diuresis following hysterectomy

Despite literature documenting ureteral obstruction associated with certain gynecological conditions, the occurrence of diuresis among posthysterectomy patients has not been examined. This nonexperimental exploratory study investigated whether diuresis was greater following hysterectomy for conditions that could potentially cause obstruction of the urinary tract than for other conditions requiring hysterectomy. Roy's adaptation model was used to emphasize the importance of expedient detection and intervention of the resultant fluid volume deficit. A retrospective chart review of 140 posthysterectomy patients was conducted. Four strata were used to divide the sample records into one nonobstructive and three potentially obstructive conditions for surgery. A ratio of total intake divided by total output was formulated for each patient and compared between the groups. Statistically significant differences were shown by one-way analysis of variance between two of the obstructive groups and the nonobstructive group (F = 5.182; P < .05). Results of this research showed that certain obstructive conditions--uterine prolapse/endometrial cancer and leiomyomas greater than 15 week size--were linked with substantially higher postoperative urine outputs, which increase the risk of hypovolemia.
