OBJECTIVE: The purpose of this randomized controlled trial was to evaluate whether early urinary catheter removal is feasible during epidural anesthesia during gastrointestinal surgery in male patients at high risk for urinary retention.
METHODS: Male patients who underwent radical surgery for gastric or colon cancer were enrolled in this randomized controlled trial. Patients were randomized 1:1 into 2 groups: the early group, in which the urinary catheter was removed before removal of the epidural catheter on the second or third postoperative day, and the late group, in which the urinary catheter was removed after removal of the epidural catheter. The randomization adjustment factors were age (≥ 65 or < 65 years) and operative site (gastric or colon). The primary endpoint was urinary retention. The secondary endpoints were the incidence of urinary tract infection and length of postoperative hospital stay.
RESULTS: Seventy-three patients were enrolled between March 2020 and February 2024 and assigned to the Early (n = 37) and Late (n = 36) groups. Four patients withdrew their consent after randomization. The intention-to-treat analysis showed that urinary retention occurred in 4 patients (11.1%) in the early group and 1 patient (3.0%) in the late group (P = 0.20). Urinary tract infection occurred in 1 patient (3.0%) in the late group. The median postoperative hospital stay was 9 days in both groups.
CONCLUSIONS: Early urinary catheter removal in male patients undergoing gastrointestinal surgery with epidural anesthesia could increase urinary retention within the expected acceptable range.

UNASSIGNED: Urinary retention is a postoperative problem that causes pain and discomfort for patients, even when catheters are used. The potential role of magnetic therapy in treating postoperative urinary retention through acupuncture points remains uncertain. This research aims to assess the impact of magnetic therapy on urinary retention in patients undergoing surgery.
UNASSIGNED: This single-blind clinical trial study was conducted in a recovery department within an operating room and subsequently in the Surgery Department of Amin Hospital. The study took place in Isfahan in 2022, with a sample of 64 patients selected using a simple random sampling method and divided equally into two groups. In the intervention group, magnet plates were applied, while the control group received iron plates at seven specific points for duration of 35 ± 5 minutes. Demographic information, the type of urinary excretion, the duration of urinary retention, and the volume of excreted urine were recorded using a researcher-made checklist for both intervention and control groups. These data were compared and subjected to descriptive and analytical statistical analysis.
UNASSIGNED: Among the participants (N = 64), the majority were male (N = 37, 57.80%), and the mean age was 40.17 years. The Chi-square analysis revealed no significant difference between the intervention and control groups in terms of the type of urinary excretion (p = 0.106). However, the Mann-Whitney U-test demonstrated significant difference between the two groups regarding the duration required to eliminate urinary retention and the volume of excreted urine (F2,41 = 62 and F1,76 = 62; p < 0.001).
UNASSIGNED: The use of a novel approach involving magnetic therapy applied to acupuncture and reflexology points has been shown to reduce the time required for the first urination and increase the volume of urine in post-surgery patients.

OBJECTIVE: Radical hysterectomy is the standard of care for management of early-stage cervical cancer and is associated with postoperative urinary retention. No clear consensus exists regarding optimal voiding trial methodology for mitigating postoperative urinary retention. Our objective was to evaluate the association between type of postoperative voiding trial and risk of urinary retention after radical hysterectomy for cervical cancer.
METHODS: We conducted a retrospective analysis of patients undergoing radical hysterectomy for apparent early-stage cervical cancer (FIGO 2018 Stage IA2-IB2) between January 2014 and February 2023. We compared incidence of urinary retention and perioperative outcomes based on method of postoperative voiding trial (timed, autofill, or backfill). Multivariate logistic regression was used to determine association of type of void trial with absence of urinary retention within 30 days postoperatively.
RESULTS: Of the 115 patients identified, 48 (41.8%) patients completed a timed void trial, 40 (34.7%) an autofill void trial, and 27 (23.5%) a backfill void trial. 44.3% of patients developed postoperative urinary retention with no differences based on void trial (p = 0.17). Urinary retention was more likely to resolve by 7 (p = 0.012) and 30 days (p = 0.01) for patients undergoing backfill voiding trials, compared to other trials. In multivariate models, backfill void trial was associated with absence of 30-day urinary retention, compared to other trials (aOR 15.1; 95% C.I. 1.5-154.9).
CONCLUSIONS: Rates of urinary retention following radical hysterectomy do not differ based on postoperative void trial methodology. A backfill void trial following radical hysterectomy may lead to increased rates of resolution of postoperative urinary retention.

UNASSIGNED: To compare the success of establishing spontaneous micturition following immediate trial without catheter (TWOC) to delayed TWOC in males catheterized for acute urinary retention.
UNASSIGNED: In this systematic review, we included studies reporting success rates of immediate TWOC or delayed TWOC (≤30 days) among males ≥18 years of age catheterized for acute urinary retention. We excluded studies on suprapubic catheterization, postoperative/perioperative catheterization and urinary retention related to trauma. We searched the following databases: MEDLINE, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Open Grey and Clinicaltrials.gov. The search was concluded on 30 November 2022. There were no restrictions on language or publication date. Risk of bias was assessed using the ROB 2.0 and ROBINS-I tools. We did random-effects restricted maximum likelihood model meta-analyses. Certainty of evidence was assessed using GRADE.
UNASSIGNED: We included 61 studies. In two randomized controlled trials (RCTs), both with some concerns for risk of bias, including in total 174 participants, the relative success rate was 1.22 (95% CI 0.84-1.76) favouring delayed TWOC. In two comparative cohort studies, both with serious risk of bias, including 642 participants, the relative success rate was 1.18 (0.94-1.47) favouring delayed TWOC. One study was excluded from this meta-analysis because of critically low quality. Four studies reporting success rates for cohorts with immediate TWOC, all with serious risk of bias, including 409 participants, had an overall success rate of 47% (29-66). Fifty-two studies reporting success rates for cohorts with delayed TWOC, all with serious risk of bias, including 12 489 participants, had an overall success rate of 53% (49-56). The certainty of the evidence was considered low for the RCTs and very low for the rest.
UNASSIGNED: There was a limited number of appropriately designed studies addressing the research question directly. The evidence favours neither approach.

OBJECTIVE: Many patients develop bladder symptoms after radical hysterectomy. This study compared urinary outcomes following radical hysterectomy based on trial of void (TOV) timing (pre-discharge TOV versus post-discharge TOV).
METHODS: A retrospective non-inferiority study of patients at two academic tertiary referral centers who underwent radical hysterectomy between January 2010 and January 2020 was carried out. Patients were stratified according to timing of postoperative TOV: either pre-discharge or post-discharge from the hospital. Short-term urinary outcomes (including passing TOV, representation with retention) and long-term de novo urinary dysfunction (defined as irritative voiding symptoms, urgency, frequency, nocturia, stress or urgency incontinence, neurogenic bladder, and/or urinary retention) were extracted from the medical record. We hypothesized that the proportion of patients who failed pre-discharge TOV would be within a 15% non-inferiority margin of post-discharge TOV.
RESULTS: A total of 198 patients underwent radical hysterectomy for cervical (118 out of 198; 59.6%), uterine (36 out of 198; 18.2%), and ovarian (29 out of 198; 14.6%) cancer. One hundred and nineteen patients (119 out of 198, 60.1%) underwent pre-discharge TOV, of whom 14 out of 119 (11.8%) failed. Of the post-discharge TOV patients (79 out of 198, 39.9%), 5 out of 79 (6.3%) failed. The proportion of patients who failed a pre-discharge TOV was within the non-inferiority margin (5.4% difference, p = 0.23). A greater proportion of patients in the post-discharge TOV group developed long-term de novo urinary dysfunction (27.2% difference, p = 0.005). Median time to diagnosis of de novo urinary dysfunction was 0.5 years (range 0-9) in the pre-discharge TOV group versus 1.0 year (range 0-6) in the post-discharge TOV group (p > 0.05).
CONCLUSIONS: In this study, pre-discharge TOV had non-inferior short-term outcomes and improved long-term outcomes.

BACKGROUND: Labor analgesic interventions, particularly the use of opioids and epidural anaesthesia, have raised concerns regarding their potential impact on postpartum urinary retention (PUR), necessitating a comprehensive investigation into their association with this clinical outcome.
METHODS: This retrospective case-control study analysed clinical data from postpartum patients at our hospital from January 2023 to December 2023. Anaesthetic methods, including opioid and non-opioid drug usage, epidural analgesia and non-use of analgesia, were assessed. Logistic regression analysis was also performed to determine important associations with apparent PUR.
RESULTS: This study included clinical data from 54 postpartum patients with PUR and 54 without urinary retention. A higher percentage of women with apparent PUR received opioids during labour compared with those without PUR (p = 0.033). Conversely, a lower percentage of women with apparent PUR received non-opioid analgesics compared with those without PUR (p = 0.026). In addition, a higher percentage of women with apparent PUR received epidural analgesia compared with those without PUR (p = 0.041). Logistic regression analysis demonstrated that opioid consumption during labour was significantly associated with apparent PUR (odds ratio (OR) = 2.469, p = 0.022). By contrast, non-opioid consumption during labour was inversely associated with apparent PUR (OR = 0.297, 95% CI = 0.123-0.681, p = 0.005). In addition, the use of epidural analgesia during labour showed a remarkable association with apparent PUR (OR = 2.857, 95% CI = 1.289-6.552, p = 0.011).
CONCLUSIONS: Opioid use during labour and the use of epidural analgesia were identified as important risk factors for apparent PUR. These findings emphasise the need for a thoughtful and balanced approach to analgesic management during labour to minimise the risk of PUR in obstetric patients.

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR.
METHODS: A nested case-control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609).
RESULTS: The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence.
CONCLUSIONS: For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases.

BACKGROUND: Cesarean deliveries (CD) are commonly performed using neuraxial anesthesia. The use of neuraxial morphine has proven beneficial in terms of postoperative pain management; however, its effect on postoperative urine retention remains unclear.
OBJECTIVE: To determine whether morphine injection into the neuraxis during CD influences postoperative urinary retention rate.
METHODS: We conducted a retrospective case-control observational study of patients undergoing CD. We compared patients using morphine injected into the intrathecal or epidural spaces (November 2020 to October 2021) to a historical cohort of patients undergoing CD without morphine (November 2019 to October 2020). The primary outcome was the rate of postoperative overt urinary retention necessitating bladder catheterization.
RESULTS: The study group comprised 283 patients, and 313 patients in the control group were eligible for analysis. No differences were found with respect to the baseline demographic and indication for CD. The number of postpartum urinary bladder catheterizations due to urine retention was higher in the study group (5% vs. 1%, P-value = 0.003). No cases of 30-day readmission were recorded. Moreover, patients treated with neuraxial morphine required fewer repeat doses of postoperative anesthesia (oral analgesia 7.4 vs. 10.1, intravenous analgesia 0.29 vs. 0.31, oral opioids 0.06 vs. 3.70, intravenous opioids 0.01 vs. 0.45, P-value < 0.001 for all).
CONCLUSIONS: While neuraxial morphine used during CD appears to be safe and effective, the risk of postoperative urinary retention seems to be increased due to its use. Cases of overt urinary retention treated by bladder catheterization does not lead to short-term complications.

UNASSIGNED: In recent years, severe pain after perianal surgery has seriously affected the prognosis of hospitalized patients. How to maximize the improvement of postoperative pain and perioperative comfort becomes particularly important.
UNASSIGNED: This study was a double-blind randomized controlled trial (Registration No.: ChiCTR2100048760, Registration Date: 16 July 2021, Link: www.chictr.org.cn/showproj.html?proj=130226), and patients were randomly divided into two groups: one group underwent postoperative 20 mL bilateral pudendal nerve block with 0.5% ropivacaine (P group), and the other group underwent postoperative 20 mL bilateral pudendal nerve block with 0.5% ropivacaine + 8 mg dexamethasone (PD group). The primary outcome was the incidence of moderate to severe pain at the first postoperative dressing change. Secondary outcomes included Quality of recovery-15 (QoR-15) score at 3 days after surgery, sleep quality, pain score at 3 days after surgery, and incidence of adverse events.
UNASSIGNED: In the main outcome indicators, the incidence was 41.7% in the P group and 24.2% in the PD group (p = 0.01). The QoR-15 score and sleep quality in PD group were better than those in P group 2 days before surgery. The incidence of postoperative urinary retention was significantly decreased in PD group (p = 0.01).
UNASSIGNED: Local anesthesia with dexamethasone combined with pudendal nerve block after perianal surgery can reduce the incidence of moderate to severe pain during the first dressing change. This may be one of the approaches to multimodal analgesia after perianal surgery.
