Urinary retention is a common complication among patients after haemorrhoidectomy. Although Crede's method is recommended for urinary retention in nursing practice textbooks, its effects require further examination. The purpose of this study was to investigate the rate of urine voiding within the first 8 h following haemorrhoidectomy and to examine the effects of Crede's method on this postoperative outcome. A two-group comparison study was conducted. All participants were over 20 years of age, and each had undergone haemorrhoidectomy. Outcome measurements included patients' self-reported urine voiding within 8 h of surgery, personal demographics and disease-related data. Before the surgical procedure, participants were divided into Crede's group and non-Crede's group, and written educational materials were given. Patients in the Crede's group were taught Crede's method for application in the event that they were unable to void urine after haemorrhoidectomy. The non-Crede's group patients were taught traditional methods without Crede's method. We examined urine voiding within the first 8 h after haemorrhoidectomy. The mean rate of urine voiding within 8 h of surgery was 60·9% overall, with 91·3% (21/23) in the Crede's group and 30·4% (7/23) in the non-Crede's group reporting successful voiding. After controlling for the two groups' personal characteristics and disease-related variables, age, educational level and perioperative fluid administration were treated as covariates and included in the multinomial logistic regression model. The odds ratio of urine voiding within the first 8 h after surgery was 52·70-fold higher in the Crede's group than in the non-Crede's group (p < 0·01). This study shows that Crede's method is an effective strategy to aid in urine voiding within the first eight postsurgical hours among patients following haemorrhoidectomy. Clear and concise information about urinary retention and related management strategies should be given to patients before haemorrhoidectomy.

Aims and objectives. The purpose of this study was to explore the prevalence and risk factors of urine retention among posthaemorrhoidectomy recipients. Background. Haemorrhoids are one of the most common functional disorders of the anus. The Haemorrhoidectomy surgical procedure is one of the primary treatments for more severe haemorrhoidal occurrences, such as for third- and/or fourth-degree haemorrhoid conditions. Urine retention is a common acute complication after operation, but rare study conducted by nurses in Taiwan to explore the prevalence and risk factors. Design. A retrospective chart review was conducted. Methods. Data from a prospectively maintained database on patients who had undergone haemorrhoidectomy between April 2004 – August 2008 were retrospectively analysed. A total of 469 charts were used in this analysis. The following outcomes were studied: patient profiles, haemorrhoid type and severity, anaesthesia methods, length of operating room stay, urine retention and management, intravenous fluid given during operation and length of stay. Results. The overall urinary retention rate was 32·8% (n = 153). Significant risk factors associated with postoperative urinary retention included severity of haemorrhoid and anaesthesia methods. Logistic regression analysis revealed that epidural anaesthesia (p = 0·008), spinal anaesthesia (p = 0·016) and haemorrhoids with a severity of three degrees or higher (p = 0·017) were predictors of urinary retention post haemorrhoidectomy. Conclusions. Acute urinary retention can have an adverse effect on a patient’s quality of care. Careful follow-up of patients with these risk factors can help nurses spot posthaemorrhoidectomy urinary retention early. Relevance to clinical practice. The prevalence of acute urinary retention post haemorrhoidectomy is common. Surgical ward nurses should therefore take the responsibility regarding the impact of urinary retention and seeking appropriate nursing interventions of induced urination.
