OBJECTIVE: We aimed to determine the incidence and risk factors for post-operative urinary retention (POUR) following surgery for perineal tears, and to determine the time to normal voiding after POUR.
METHODS: This was a prospective cohort study of women who underwent surgery for old (≥ 3 months) obstetric perineal tears from January 2022 to December 2023. The diagnosis of POUR was made in a woman who completely failed to void despite a full bladder or, one who had post-void residual (PVR) > 150 ml within 10 min of voiding. Return to normal voiding was considered if a patient with POUR had two consecutive PVRs of ≤ 150 ml. Descriptive analyses and multivariable logistic regression were performed to determine risk factors for POUR.
RESULTS: A total of 153 participants were enrolled in this study with a mean age of 35.9 (SD ± 10.8) years. The incidence of POUR was 19.6% (30/153, 95% CI 14.02-26.7), and the median time to normal voiding for these patients was 42.4 h (range 24-72). Risk factors for POUR included repeat perineal tear surgery (RR = 4.24; 95% CI 1.16-15.52; p = 0.029) and early urinary catheter removal (RR = 2.89; 95% CI 1.09-7.67; p = 0.033).
CONCLUSIONS: Post-operative urinary retention following surgery for perineal tears is common. The time to return to normal voiding in patients with POUR is short. Women having repeat perineal tear surgery and those in whom the urinary catheter is removed early were more likely to experience POUR. Delayed urinary catheter removal could be considered, especially in patients undergoing repeat perineal tear surgery.

UNASSIGNED: Post-operative urinary retention (POUR) is a frequent complication following surgical procedures, characterized by an acute inability to void, leading to additional complications and extended hospitalization. Acupuncture has been shown to be effective in facilitating spontaneous urination and alleviating anxiety in patients experiencing poor urination. The present study aims to evaluate the effectiveness of electroacupuncture in the management of POUR in patients who have undergone lumbar spine surgery.
UNASSIGNED: This retrospective study conducted at the National Hospital of Acupuncture in Vietnam and reviewed the medical records of patients over 18 years old who underwent lumbar spine surgery and were diagnosed with POUR between January to December 2019. Electroacupuncture was administered at five specific acupuncture points Qugu (CV2), Zhongji (CV3), Zhibian (BL54), Pangguanshu (BL28), and Kunlun (BL60). This study monitored key parameters related to the effectiveness of the acupuncture treatment, including the number of acupuncture treatment sessions required until a patient was successfully treated was recorded, with a maximum of three acupuncture treatment sessions per patient, the time elapsed until urination following the treatment (minutes), and urinary bladder volume before and after treatment (mL).
UNASSIGNED: The study demonstrated a 93.3% success rate in treating POUR with electroacupuncture. A significant reduction in post-void residual volume was noted, and patients could void within 30 minutes post-treatment. No significant differences in treatment effectiveness were observed across difference genders and age groups.
UNASSIGNED: Electroacupuncture proved to be a highly effective treatment for POUR in patients post-lumbar spine surgery, with a rapid response time and substantial reduction in PVR. However, the retrospective nature of the study and single-center focus limit its generalizability. Future research incorporating randomized controlled trials or multi-center observational studies are recommended to validate these findings and explore the potential of acupuncture in POUR management on a broader scale.

OBJECTIVE: Post-operative urinary retention (POUR) is a known complication of hernia surgery. Minimally invasive inguinal hernia repair (IHR) is typically done under general anesthesia with neuromuscular blockade (NMB), which is commonly reversed with an anticholinesterase inhibitor paired with an anticholinergic agent. Sugammadex is a unique NMB reversal agent that does not have to be paired with an anticholinergic. We sought to explore the role of sugammadex in reducing the rate of POUR following these procedures.
METHODS: Data were collected retrospectively at a single institution between February 2016 and October 2019. We identified and studied patients who underwent minimally invasive IHR and received either sugammadex or neostigmine/glycopyrrolate for NMB reversal. The primary endpoint was POUR requiring bladder catheterization. Secondary endpoints included post-operative and 30-day readmissions.
RESULTS: 274 patients were included in this study (143 received neostigmine and glycopyrrolate, 131 sugammadex). The sugammadex patients were on average 5 years older than the neostigmine/ glycopyrrolate patients (63.2 vs 58.2, p = 0.003), and received less median intravenous fluids (IVF) (900 ml vs 1000 ml; p = 0.015). There was a significant difference in the rate of POUR between the sugammadex and neostigmine/glycopyrrolate patients (0.0% vs 8.4%, p ≤ 0.001). The difference remained significant after controlling for age and IVF. The odds of POUR for those who received neostigmine/glycopyrrolate were 25 × higher than the odds of those who received sugammadex.
CONCLUSIONS: The results of this study reflect the protective role of sugammadex against POUR in minimally invasive IHR cases.

Tamsulosin is a therapeutic drug of alpha-adrenergic antagonists. Previous randomized controlled trials and retrospective analyses have proved the efficacy of tamsulosin on many urinary system diseases. However, there is still a conflict about whether tamsulosin could prevent postoperative urinary retention (POUR). This meta-analysis aims to probe into the efficacy of tamsulosin for preventing POUR versus placebo. We searched MEDLINE, EMBASE, and Cochrane Library from December 31, 1999 to April 30, 2022, for randomized controlled trials (RCTs). Studies that were not RCTs or without negative controls were excluded. Cochrane Collaboration harmonized criteria were used to assess the risk of bias in included studies. Revman (version 5.3) software was invited to synthesize the results. We performed subgroup analyses to explore the factors that could influence tamsulosin\'s efficacy in POUR prevention. Our meta-analysis pooled 13 RCTs with 2163 patients. We concluded that tamsulosin brought about a significant reduction in the risk of POUR versus placebo (13.54% vs 20.88% for tamsulosin vs placebo, RR = 0.63, 95% CI 0.47 to 0.84, P = 0.002). Tamsulosin could significantly reduce the risk of POUR in abdominal (11.52% vs 20.25% for tamsulosin vs placebo, RR = 0.52, 95% CI 0.31 to 0.88, P = 0.02) and female pelvic surgery (15.57% vs 31.50% for tamsulosin vs placebo, RR = 0.51, 95% CI 0.31 to 0.82, P = 0.006) but not in spinal surgery (13.45% vs 12.75% for tamsulosin vs placebo, RR = 1.07, 95% CI 0.72 to 1.60, P = 0.73) and lower limb surgery (21.43% vs 33.33% for tamsulosin vs placebo, RR = 0.64, 95% CI 0.35 to 1.14, P = 0.13). The preventive effect of postoperative (17.70% vs 33.93% for tamsulosin vs placebo, RR = 0.53, 95% CI 0.33 to 0.85, P = 0.008) and postoperative with preoperative tamsulosin (13.96% vs 23.44% for tamsulosin vs placebo, RR = 0.64, 95% CI 0.43 to 0.93, P = 0.02) on POUR were significantly better than preoperative management (11.95% vs 14.63% for tamsulosin vs placebo, RR = 0.62, 95% CI 0.23 to 1.65, P = 0.34). Postoperative catheter placement appears to have a negative impact on the POUR-preventive effect of tamsulosin. (9.37% vs 16.46% for tamsulosin vs placebo, RR = 0.51, 95% CI 0.31 to 0.83, P = 0.007) Tamsulosin showed significantly effect on POUR prevention in patients during spinal (15.07% vs 26.51% for tamsulosin vs placebo, RR = 0.52, 95% CI 0.31 to 0.90, P = 0.02) and epidural anesthesia (12.50% vs 29.79% for tamsulosin vs placebo, RR = 0.42, 95% CI 0.18 to 1.00, P = 0.05) but not in general anesthesia (12.40% vs 18.52% for tamsulosin vs placebo, RR = 0.68, 95% CI 0.45 to 1.03, P = 0.07). Tamsulosin shows better outcomes for preventing POUR than placebo. Besides, tamsulosin showed a different effect on POUR prevention in the various surgical sites, anesthesia, medication management, and catheter use. However, our conclusions still have some limitations due to the lack of evidence.

BACKGROUND: Postoperative urinary retention (POUR) is a significant problem in total joint arthroplasty (TJA). Although risk factors for POUR have been well documented, they are ubiquitous in an aging total joint population, which makes risk stratification difficult. The purpose of this study was to determine if a high preoperative post-void bladder scan identifies patients at risk for POUR.
METHODS: A retrospective analysis was conducted on all TJAs performed at a high-volume orthopedic center between December 2019 and February 2020. A total of 585 elective TJA patients received post-void bladder scans before surgery. Bladder scan volumes were correlated with catheterization via Chi-squared tests.
RESULTS: A high post-void residual volume (PVRV > 50 ml) was associated with an increased risk of catheterization (23% vs 34%, chi-squared statistic = 6.2638, P value = .013), as was intravenous fluid volume (>1000 ml in knee, >2000 ml in hip). Catheterization rates were higher among total knee arthroplasty patients younger than 60 years (37% vs 24%, chi-squared statistic = 4.284, P value = .0385) and total hip arthroplasty (THA) patients older than 65 years (30% vs 18%, chi-squared statistic = 3.292, P value = .0695). Multiple risk factors were additive.
CONCLUSIONS: Higher PVRV and intravenous fluids were independently associated with catheterization after TJA. Younger age was associated with greater risk in total knee arthroplasty, while older age increased risk in THA. We propose that a preoperative bladder scan to detect a high PVRV may provide clinical utility to identify patients likely to develop POUR.

UNASSIGNED: To assess the efficacy in lowering post-operative urinary retention, urinary tract infection and lower urinary tract symptoms and the incidence of adverse events among 12 interventions and to perform risk-benefit analysis.
UNASSIGNED: Previous randomized controlled trials were identified from MEDLINE, Scopus and CENTRAL database up to January 2020. The interventions of interest included early ambulation, fluid adjustment, neuromodulation, acupuncture, cholinergic drugs, benzodiazepine, antispasmodic agents, opioid antagonist agents, alpha-adrenergic antagonists, non-steroidal anti-inflammatory drugs (NSAIDs) and combination of any interventions. The comparators were placebo or standard care or any of these interventions. Network meta-analysis was performed. The probability of being the best intervention was estimated and ranked using rankogram and surface under the cumulative ranking curve. Risk-benefit analysis was done. Incremental risk-benefit ratio (IRBR) was calculated and risk-benefit acceptability curve was constructed.
UNASSIGNED: A total of 45 randomized controlled trials with 5387 patients was included in the study. Network meta-analysis showed that early ambulation, acupuncture, alpha-blockers and NSAIDs significantly reduced the post-operative urinary retention. Regarding urinary tract infection and lower urinary tract symptoms, no statistical significance was found among interventions. Regarding the side effects, only alpha-adrenergic antagonists significantly increased the adverse events compared with acupuncture and opioid antagonist agents from the indirect comparison. According to the cluster ranking plot, acupuncture and early ambulation were considered high efficacy with low adverse events, corresponding to the IRBR.
UNASSIGNED: Early ambulation, acupuncture, opioid antagonist agents, alpha-adrenergic antagonists and NSAIDs significantly reduce the incidence of post-operative urinary retention with no difference in adverse events. Regarding the risk-benefit analysis of the medical treatment, alpha-adrenergic antagonists have the highest probability of net benefit at the acceptable threshold of side effect of 15%, followed by opioid antagonist agents, NSAIDs and cholinergic drugs.

BACKGROUND: Postoperative urinary retention (POUR) is a common hip fracture (HF) complication. Although fecal impaction (FI) is one of the oft-cited causes of POUR in clinical practice, evidence regarding this association is scarce.
OBJECTIVE: The aim of this study was to determine whether FI was associated with POUR after HF surgery in older patients.
METHODS: All patients consecutively admitted after a HF surgery in a geriatric perioperative unit were included in this cross-sectional study. FI was systematically assessed by a digital rectal exam at admission and according to clinical suspicion during the hospital stay. The dependent variable was POUR, systematically screened according to the department protocol and defined as a bladder volume>400ml requiring catheterization. The association between FI and POUR was assessed by multivariable analysis.
RESULTS: A total of 256 patients were included (mean [SD] age 86 [6] years), (76% women): 108 (42%) presented FI and 63 (25%) POUR. The frequency of FI was higher with than without POUR (73% vs. 32%, P<0.001). On multivariable analysis, after adjusting for age, sex, Cumulative Illness Rating Scale score and anticholinergic load, FI was the only factor independently associated with POUR (odds ratio 4.78) [95% confidence interval 2.44-9.71], P<0.001.
CONCLUSIONS: FI was the only independent factor associated with POUR after HF surgery in older adults. Further studies are needed to optimize perioperative geriatric care including FI and POUR assessment and management.

We tested the hypothesis that women can subjectively determine if they have emptied their bladder after a spontaneous voiding attempt following urogynecological surgery to rule out post-operative urinary retention as determined by a voiding trial.
This is a prospective observational study of women undergoing urogynecological surgery at two academic institutions from June 2016 to March 2019. Following surgery, subjects underwent a voiding trial followed by measurement of the PVR via ultrasound bladder scan or straight catheterization. A successful voiding trial was defined as a PVR of ≤150 ml. Subjects were queried about their subjective sensation of bladder emptying; \"Do you feel that you completely emptied your bladder?\" Their responses were either \"Yes\", \"No\" or \"I don\'t know\". Their subjective responses were correlated with the voiding trial results using a Chi-squared analysis for sensitivity, specificity, and positive (PPV) and negative predictive values (NPV).
A total of 266 subjects were included in the final evaluation. The screening subjective question had a sensitivity of 85.7% (CI 71.46 to 94.57%), a specificity of 91.5% (CI 87.01 to 94.79%), a PPV of 65.4% (CI 54.78 to 74.77%), and an NPV of 97.14% (CI 94.18 to 98.62%) to detect a failed voiding trial.
The NPV of the subjective question regarding bladder emptying in the post-operative urogynecological setting is high at >97%, suggesting that it might be reasonable to forgo a formal voiding trial in patients who subjectively feel that they have emptied their bladder.

Post-operative urinary retention is a common problem affecting close to half of all women undergoing pelvic reconstructive surgery. This was an exploratory analysis that was aimed at identifying factors associated with an inability to learn clean intermittent self-catheterization (CISC) after a failed post-operative retrograde voiding trial (RGVT).
We performed a retrospective case-control study of women who underwent pelvic organ prolapse or urinary incontinence surgery within a single division from 2016 to 2018. We compared women who could learn CISC with those unable to learn and discharged home with an indwelling catheter (IC). Analyses were carried out using Fisher\'s exact test, the Mann-Whitney U test, the Chi-squared test, and the t test with logistic regression.
Of the 202 women who failed their RGVT, 134 (66.3%) were able to learn CISC and 68 (33.7%) were not. Older age, urinary incontinence, diabetes and colpectomy/colpocleisis were associated with an inability to learn CISC (p < 0.05). Women with an IC were more likely to have an office visit related to catheter care (65.7% vs 5.2%, p < 0.001). A UTI within 30 days of surgery was more common with CISC (16.4% vs 6.0%, p = 0.037). In a multivariate logistic regression model, each increasing year of age was associated with a 1.036-fold decrease in the ability to learn CISC (aOR 1.036, 95% CI 1.002-1.071; p = 0.04).
Increasing age was the only variable identified on multivariate logistic regression as a risk factor for failure to learn CISC. Further studies are needed to identify barriers to learning post-operative self-catheterization.

Spinal anesthesia has been reported to be a risk factor for postoperative urinary retention (POUR) in various surgical specialties. We hypothesized that spinal anesthesia was a risk factor for POUR after outpatient vaginal surgery for pelvic organ prolapse (POP).
This was a retrospective review of an urogynecology database for all outpatient POP vaginal surgeries performed in 2014 to evaluate the risk of POUR after general versus spinal anesthesia. A standardized voiding trial was performed by backfilling the bladder with 300 ml of saline. A successful trial was achieved if the patient voided two-thirds of the total volume instilled, confirmed by bladder ultrasound. Our primary outcome was to compare POUR requiring discharge with a Foley catheter between spinal and general anesthesia. Multivariate logistic regression was performed for variables with significance at p < 0.1 at the bivariate level.
A total of 177 procedures were included, 126 with general and 51 with spinal anesthesia. The overall POUR rate was 48.9%. Type of anesthesia was not a risk factor for POUR. Multivariate logistic regression demonstrated that age < 55 years (adjusted odds ratio [OR] 3.73; 95% confidence interval [CI], 1.31-11.7), diabetes (adjusted OR 4.18, 95% CI 1.04-21.67), and having a cystocele ≥ stage 2 (adjusted OR 4.23, 95% CI 1.89-10) were risk factors for developing POUR.
Acute urinary retention after outpatient vaginal pelvic floor surgery can vary by procedure, but overall is 48.9%. Spinal anesthesia does not contribute to POUR, but rates are higher in those women that are younger than 55 years of age, have a cystocele ≥ stage 2 preoperatively, and a history of diabetes.
