RESUMO
Background: Urethral calculi causing acute urinary retention is a highly uncommon condition in women, which poses distinctive difficulties in diagnosis and treatment. This report presents the case of a 52-year-old woman who experienced acute urinary retention caused by a urethral stone. It emphasizes the effective use of minimally invasive methods and underscores the importance of comprehensive multidisciplinary treatment. Case presentation: A 52-year-old woman patient arrived with acute urinary retention symptoms that lasted 6 hours. She complained of pain in the perineal and periurethral regions. She struggled with poorly managed type 2 diabetes, metabolic syndrome, and frequent cystitis. The examination showed the presence of a 2-cm stone in the urethra. The treatment utilised retrograde propulsion and laser fragmentation. Postoperative magnetic resonance imaging results were normal, and follow-up care involved managing diabetes and adopting lifestyle changes to prevent the recurrence of cystitis and stones for 6 months. Conclusion: Urethral calculi exceptionally cause acute urinary retention in women. To achieve successful outcomes and prevent recurrence, it is crucial to prioritize prompt, minimally invasive treatment, and comprehensive management.
RESUMO
PURPOSE: To investigate the diagnostic performance of an automatic pipeline for detection of hydronephrosis on kidney's parenchyma on unenhanced low-dose CT of the abdomen. METHODS: This retrospective study included 95 patients with confirmed unilateral hydronephrosis in an unenhanced low-dose CT of the abdomen. Data were split into training (n = 67) and test (n = 28) cohorts. Both kidneys for each case were included in further analyses, whereas the kidney without hydronephrosis was used as control. Using the training cohort, we developed a pipeline consisting of a deep-learning model for automatic segmentation (a Convolutional Neural Network based on nnU-Net architecture) of the kidney's parenchyma and a radiomics classifier to detect hydronephrosis. The models were assessed using standard classification metrics, such as area under the ROC curve (AUC), sensitivity and specificity, as well as semantic segmentation metrics, including Dice coefficient and Jaccard index. RESULTS: Using manual segmentation of the kidney's parenchyma, hydronephrosis can be detected with an AUC of 0.84, a sensitivity of 75% and a specificity of 82%, a PPV of 81% and a NPV of 77%. Automatic kidney segmentation achieved a mean Dice score of 0.87 and 0.91 for the right and left kidney, respectively. Additionally, automatic segmentation achieved an AUC of 0.83, a sensitivity of 86%, specificity of 64%, PPV of 71%, and NPV of 82%. CONCLUSION: Our proposed radiomics signature using automatic kidney's parenchyma segmentation allows for accurate hydronephrosis detection on unenhanced low-dose CT scans of the abdomen independently of widened renal pelvis. This method could be used in clinical routine to highlight hydronephrosis to radiologists as well as clinicians, especially in patients with concurrent parapelvic cysts and might reduce time and costs associated with diagnosing hydronephrosis.

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: Intrathecal morphine provides effective analgesia for a range of operations. However, widespread implementation into clinical practice is hampered by concerns for potential side-effects. We undertook a systematic review, meta-analysis, and meta-regression with the primary objective of determining whether a threshold dose for non-pulmonary complications could be defined and whether an association could be established between dose and complication rates when intrathecal morphine is administered for perioperative or obstetric analgesia. METHODS: We systematically searched the literature for randomised controlled trials comparing intrathecal morphine vs control in patients undergoing any type of surgery under general or spinal anaesthesia, or women in labour. Primary outcomes were rates of postoperative nausea and vomiting, pruritus, and urinary retention within the first 24 postoperative hours, analysed according to doses (1-100 µg; 101-200 µg; 201-500 µg; >500 µg), type of surgery, and anaesthetic strategy. Trials were excluded if doses were not specified. RESULTS: Our analysis included 168 trials with 9917 patients. The rates of postoperative nausea and vomiting, pruritus, and urinary retention were significantly increased in the intrathecal morphine group, with an odds ratio (95% confidence interval) of 1.52 (1.29-1.79), P<0.0001; 6.11 (5.25-7.10), P<0.0001; and 1.73 (1.17-2.56), P=0.005, respectively. Meta-regression could not establish an association between dose and rates of non-pulmonary complications. There was no subgroup difference according to surgery for any outcome. The quality of evidence was low (Grading of Recommendations Assessment, Development, and Evaluation [GRADE] system). CONCLUSIONS: Intrathecal morphine significantly increased postoperative nausea and vomiting, pruritus, and urinary retention after surgery or labour in a dose-independent manner. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42023387838).
RESUMO
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. CONCLUSION: 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.

INTRODUCTION AND HYPOTHESIS: 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.
RESUMO
Background: Transanal total mesorectal excision has emerged as a potential solution to certain limitations associated with laparoscopic total mesorectal excision in rectal cancer patients. Differences in surgical approaches have raised questions regarding their impact on the risk of postoperative urinary retention, with limited data available from large scale randomized clinical study. Objective: To report incidence of postoperative urinary retention and evaluate the associated risk factors for transanal total mesorectal excision. Design: In this randomized controlled trial (ClinicalTrials. gov NCT06147492), we retrieved 524 patients who received total mesorectal excision (TME) for stage I-III rectal cancer between June 2019 and April 2022, and the patients were randomly assigned in a 1:1 ratio to undergo either taTME or laTME. Patients: We enrolled 524 patients who underwent total mesorectal excision for stage I-III rectal cancer between June 2019 and April 2022. Main outcome measures: The incidence of postoperative urinary retention. Results: Among the 524 enrolled patients, 261 were randomized to the laTME group, while 263 were were randomized the taTME group. The median age was 58 years, and 340 participants (64.8 %) were male. Notably, 37 individuals (7.0 %) experienced postoperative urinary retention during the follow-up period, with no significant disparity was observed between the taTME and laTME groups (6.8 % and 7.2 %, respectively, P = 0.98). Risk factors associated with PUR in patients following taTME encompassed early removal of the urinary catheter (P = 0.006), net infusion rate >4.09 ml kg-1.h-1 (P = 0.006), and an age surpassing 65 years (P = 0.0321). Limitations: The generalizability of the findings outside specialist rectal cancer centers may be limited. Conclusions: Transanal total mesorectal excision was not found to heighten the risk of postoperative urinary retention. Nonetheless, it is advisable removing postoperative catheter beyond the initial day and exercising caution in the administration of intravenous fluids in clinical practice for taTME procedures.
RESUMO
Urinary retention is a common complaint encountered in the emergency department (ED). Current tools for the assessment of urinary retention are either bladder volume estimation with a bladder scanner performed by nursing staff or direct visualization and measurement via bedside ultrasound performed by an emergency physician. Newer handheld ultrasound devices such as the Butterfly iQ have been brought to the market to bring ultrasound more conveniently to the bedside. A recently released handheld auto-calculation tool produces a 3D image of the bladder and instant bladder volume measurement in milliliters. However, there is a paucity of data assessing the validity of the new Butterfly iQ at the bedside. This study sought to compare the diagnostic accuracy and rated user convenience of the nursing bladder scanner, the cart-based ultrasound machine, and the Butterfly iQ auto-bladder volume tool. ED patients were prospectively enrolled and underwent bladder measurements in a randomized, pre-determined order with each modality. Measurements were subsequently compared to the gold standard of catheterization. Cart-based ultrasound had the highest agreement to catheterization when compared to the RN scanner and the Butterfly iQ. However, the Butterfly iQ and RN scanner were both considered more convenient measurement modalities than the cart-based ultrasound. The Butterfly iQ serves as a cost-effective alternative to cart-based ultrasound while providing greater general utility compared to bladder scanners.
RESUMO
OBJECTIVES: 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.
RESUMO
Objective: To compare the success of establishing spontaneous micturition following immediate trial without catheter (TWOC) to delayed TWOC in males catheterized for acute urinary retention. Materials and methods: 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. Results: 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. Conclusion: There was a limited number of appropriately designed studies addressing the research question directly. The evidence favours neither approach.
RESUMO
Herpes simplex virus (HSV) infections necessitate careful management of urinary dysfunction and retention, which are underestimated conditions. Here, we present a rare case of HSV encephalomyeloradiculitis in a 76-year-old man, whose initial symptoms included urinary dysfunction and retention that alone lasted for approximately 1 week. Unlike in meningoencephalitis, high fever and headache were absent; however, the patient subsequently developed cauda equina syndrome and consciousness disturbance. Gadolinium-enhanced spinal MRI suggested enhanced cauda equina at the L2/3 level. Upon admission, he was treated for meningoencephalitis with acyclovir and steroid pulse therapy. Subsequent cerebrospinal fluid analysis result was positive for HSV DNA. A |brain MRI conducted 1 week after admission displayed high-intensity lesions in the white matter of the right temporal lobe, confirming HSV encephalomyeloradiculitis. These treatments were highly effective and gradually improved the patient's condition. He was discharged 1 month after hospitalization, and the urinary catheter was removed 2 weeks later. HSV infections can cause life-threatening encephalomyeloradiculitis. Therefore, both neurologists and urologists must pay attention to their occurrence and characteristics in clinical settings.
RESUMO
Hematometrocolpos is an infrequent congenital anomaly (Mullerian duct anomaly) that results in an imperforate hymen, followed by accumulation of menstrual blood in the vagina and or uterus in prepubertal girls results in retrograde menstruation. This commonly manifests as abdominal pain in premenarcheal pubescent girls. We discuss the case of two adolescent girls who presented to the emergency with lower abdominal pain, constipation, back pain, and/or urinary retention. They were found to have an imperforate hymen and hematometrocolpos. The diagnosis was made with the use of a genital examination and ultrasound. Hymenotomy was performed successfully in both cases and the patients recovered completely without complications. Failure to diagnose premenstrual girls presenting with lower abdominal pain and/or retention of urine with hematometrocolpos might lead to complications like infertility, endometriosis, tubal infections, adhesions, etc.
RESUMO
BACKGROUND: Inguinal hernia repair (IHR) is a common surgical procedure worldwide. Although IHR can be performed by the minimally invasive method, which accelerates recovery, postoperative urinary retention (POUR) remains a common complication that significantly impacts patients. Thus, it is essential to identify the risk factors associated with POUR to diminish its negative impact. METHODS: We conducted a single-center retrospective review of elective IHR from 2018 to 2021. POUR was defined as the postoperative use of straight catheter or placement of an indwelling catheter to relieve the symptoms. Adjusted multivariate regression analysis was performed to address the associations of clinicodemographic, surgical, and intraoperative factors with POUR. RESULTS: A total of 946 subjects were included in the analysis after excluding cases of emergent surgery, recurrent hernia, or concomitant operations. The median age was 68.4 years, and 92.0% of the patients were male. Twenty-three (2.4%) patients developed POUR. In univariate analysis, POUR in comparison with non-POUR was significantly associated with increased age (72.2 versus 68.3 years, P = 0.012), a greater volume of intraoperative fluid administered (500 versus 400 ml, P = 0.040), and the diagnosis with benign prostate hypertrophy (34.8% versus 16.9%, P = 0.025). In the multivariate model, both increased age (odds ratio [OR] 1.04, 95% CI 1.01-1.08; P = 0.049) and a greater volume of intraoperative fluid administered (OR 1.12 per 100-mL increase, 95% CI 1.01-1.27; P = 0.047) were significantly associated with the occurrence of POUR. CONCLUSIONS: We found that increased age and a greater volume of intraoperative fluid administered were significantly associated with the occurrence of POUR. Limiting the administration of intraoperative fluid may prevent POUR. From the perspective of practical implications, specific guidelines or clinical pathways should be implemented for fluid management and patient assessment.
RESUMO
During the assessment of a third-degree atrioventricular (AV) block in a patient with syncope, different etiologies should be considered and evaluated. Extrinsic vagal paroxysmal AV block, extrinsic idiopathic AV block and intrinsic paroxysmal AV block are among the types of third-degree AV block in the differential diagnoses. Extrinsic vagal paroxysmal third-degree atrioventricular block (EV-AVB) is linked to parasympathetic influence on cardiac conduction and can be observed in bladder distention and urinary retention. Topical and ophthalmic beta-blockers have shown systemic effects such as bradycardia with and without syncope. We present the case of an 80-year-old male with symptomatic EV-AVB likely precipitated by bladder outlet obstruction and chronic use of an ophthalmic beta-blocker, often overlooked causes of third-degree AV block.
RESUMO
Acute urinary retention is uncommon in pediatric age and is usually associated with infection or obstruction of the urinary tract. We present the case of a 12-year-old girl admitted to the emergency room with acute urinary retention and lower urinary tract symptoms. Physical examination revealed abdominal distension and a blue-bulging mass occupying the vaginal introitus. Ultrasound confirmed the diagnosis of hematocolpos and revealed hydronephrosis, caused by compression. Kidney function and urinalysis were normal. A hymen incision and excision of redundant tissue were performed without complications. Hematocolpos is a condition caused by obstructive uterovaginal deformity. Imperforate hymen is responsible for most of the cases and usually manifests as primary amenorrhea and cyclic lower abdominal pain. The diagnosis of hematocolpos can be challenging. However, it is important to consider it in female adolescents without menarche presenting with acute urinary retention.
RESUMO
OBJECTIVE: To determine the association between timing of indwelling catheter removal and urinary retention after cesarean. DESIGN: Retrospective cohort study. SETTING: Eight hospitals in suburban, rural, and urban Colorado and Montana. PARTICIPANTS: Women who gave birth by cesarean from January 1, 2021, to April 30, 2022 (N = 3,496). METHODS: We categorized participants who gave birth between January 1, 2021, and June 29, 2021, (before implementation of the Enhanced Recovery After Surgery initiative) into Group A and participants who gave birth between July 1, 2021, and April 30, 2022, (after implementation of the Enhanced Recovery After Surgery initiative) into Group B. We used descriptive statistics to report the proportion of participants in both groups who experienced urinary retention after birth. We performed chi-square tests to determine the association between the time of catheter removal and incidence of urinary retention. We used the Wilcoxon rank sum test to determine the association between length of stay and urinary retention. RESULTS: Urinary retention rates were 5.8% in Group A and 12.6% in Group B (p < .001). In both groups, participants who received epidural anesthesia experienced significantly more urinary retention than those who received spinal anesthesia (p < .001). Participants who received epidural anesthesia and experienced urinary retention pushed 16.9% longer than those without urinary retention (p < .001). The proportion of participants who experienced urinary retention after catheter removal was 19.4% at 7 hours, 4.6% at 16 hours, and 9.9% at 12 hours after birth. Length of stay was determined to be inconclusive. CONCLUSION: We determined that the optimal time of catheter removal to minimize the rate of urinary retention was 12 to 16 hours after cesarean among women who received morphine sulfate as the spinal anesthesia.
RESUMO
INTRODUCTION AND HYPOTHESIS: 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). CONCLUSION: 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.
RESUMO
Acute urinary retention caused by uterine incarceration due to adenomyosis is a rare phenomenon with limited documented cases. This report details the case of a 38-year-old female with acute urinary retention. A pelvic MRI revealed an enlarged retroverted uterus with a mass on the posterior left of the myometrium, indicative of adenomyosis. The size and anatomical location of the mass suggested uterine incarceration with direct pressure on the urinary bladder neck, leading to urinary retention. The patient underwent total abdominal hysterectomy, bilateral salpingectomy, and adhesiolysis. Subsequent follow-ups at one and three months post-surgery showed the resolution of urinary symptoms, underscoring the importance of considering adenomyosis as a potential cause of urinary retention in women with lower urinary tract symptoms. Timely recognition and appropriate intervention are crucial for mitigating complications and improving outcomes in these patients, as illustrated in this case.
RESUMO
BACKGROUND: There are conflicting reports on the factors that increase the likelihood of postpartum urinary retention (PUR). OBJECTIVES: We completed an updated systematic review and meta-analysis to identify the risk factors for PUR. SEARCH STRATEGY: An exhaustive search of the literature was undertaken using multiple databases, including PubMed, Web of Science, the Cochrane Library, and Embase to identify pertinent studies published up until November 4, 2023. SELECTION CRITERIA: Observational studies that provided outcomes to calculate the risk factors for PUR were included. DATA COLLECTION AND ANALYSIS: Two investigators separately performed the extraction of pertinent data from the articles. The risk factors for PUR were identified by pooling adjusted and unadjusted odds ratios (ORs) and 95% confidence intervals (CIs). Heterogeneity test, sensitivity analysis, and publication bias assessment were performed. MAIN RESULTS: This meta-analysis included 21 studies with a total of 36 951 participants. Meta-analysis was performed for 14 risk factors, and eight of these were statistically significant. The risk factors that were identified in this review included instrumental delivery (OR, 2.96 [95% CI, 1.82-4.80]; 95% prediction interval [PI], 0.67-12.98), relatively long duration of labor (OR, 1.04 [95% CI, 1.02-1.06]; 95% PI, 1.00-1.08), episiotomy (OR, 1.56 [95% CI, 1.19-2.06] 95% PI, 0.64-3.83), nulliparity (OR, 1.55 [95% CI, 1.30-1.84]; 95% PI, 0.94-2.77), epidural analgesia (OR, 2.99 [95% CI, 1.78-5.03]; 95% PI, 0.53-16.76), labor augmentation (OR, 2.21 [95% CI, 1.49-3.28]; 95% PI, 0.12-39.26), labor induction (OR, 1.73 [95% CI, 1.12-2.66]; 95% PI, 0.40-7.39), and perineal injury (OR, 2.75 [95% CI, 1.95-3.89]; 95% PI, 1.10-6.92). CONCLUSION: Instrumental delivery, extended labor duration, episiotomy, nulliparity, epidural analgesia, labor augmentation/induction, and perineal injury are significant risk factors for PUR. The findings could help physicians identify patients at risk in the postpartum setting.
