Purpose: This study was performed to analyze the predictors that might contribute to urinary retention following semiclosed hemorrhoidectomy under spinal anesthesia.
Methods: This retrospective study enrolled 2,176 consecutive patients with symptomatic grade III to IV hemorrhoids who underwent semiclosed hemorrhoidectomy between September 2018 and September 2019.
Results: Among the 2,176 patients, 1,878 (86.3%) had no postoperative urinary retention, whereas 298 (13.7%) developed urinary retention after hemorrhoidectomy. The percentage of males was significantly higher in the retention group than in the non-retention group (60.4% vs. 48.1%; P=0.001). The risk of urinary retention was 1.52-fold higher in males than in females (95% confidence interval [CI], 1.13?2.04; P=0.005), 1.62-fold higher in old age (95% CI, 1.14?2.28; P=0.006), and 1.37-fold higher with high body mass index (BMI) (95% CI, 1.04?1.81; P=0.025). Patients with ≥4 resected hemorrhoids had a higher odds ratio (OR) of 1.46 (95% CI, 1.12?1.89; P=0.005) than patients with <4 resected hemorrhoids. Among the supplementary medication, patients who used analgesics had a higher OR of 2.06 (95% CI, 1.57?2.68; P=0.001) than those who did not.
Conclusion: Male sex, age, high BMI, number of resected hemorrhoids, and supplementary analgesics are independent risk factors for urinary retention after semiclosed hemorrhoidectomy.
