Based on current literature, evidence stating that PUR is harmless is lacking. Future research should focus on management strategies for overt PUR and the long-term consequences of covert PUR. Until these results are available, clinicians should be aware of the potential consequences and therefore keep trying to identify patients at risk of PUR and patients with the actual condition.
Background Postpartum urinary retention (PUR) is a common condition with varying prevalence. Measurement of the post-void residual volume (PVRV) is not regularly performed. Various studies have been published on overt (the inability to void after giving birth, requiring catheterisation) and covert (an increased PVRV after spontaneous micturition) PUR. To evaluate which clinical prognostic factors are related to PUR, the identification of independent risk factors for covert and overt PUR is needed.Objectives We performed a systematic review and meta-analysis of observational studies reporting on risk factors for PUR.Search strategy Systematic search of MEDLINE and EMBASE to September 2011.Selection criteria Articles that reported on women diagnosed with PUR or with an abnormal PVRV.Data collection and analysis The included articles were selected by two authors. We constructed two-by-two tables for potential risk factors of overt and covert PUR and calculated pooled odds ratios (ORs) with 95% confidence intervals.Main results Twenty-three observational studies with original data were eligible for data extraction, of which 13 could be used for meta-analysis. Statistically significant risk factors for overt PUR were epidural analgesia (OR 7.7), instrumental delivery (OR 4.5), episiotomy (OR 4.8) and primiparity (OR 2.4). For covert PUR, variety in the definitions used resulted in heterogeneity; no significant prognostic factors were found.Conclusions Instrumental delivery, epidural analgesia, episiotomy and nulliparity are statistically significantly associated with a higher incidence of overt PUR. The same factors were identified for covert PUR, but without statistical significance. Uniformity in definitions in future research is essential to create a prognostic model.
Setting A large training hospital in the Netherlands.Population Patients undergoing anterior colporrhaphy.Methods One hundred patients were included. Patients were randomised into two groups. In one group (n ¼ 50), a transurethral catheter was in place for four days post-operatively and removed on the fifth postoperative day. In the other group (n ¼ 50), catheterisation was not prolonged and the catheter was removed the morning after surgery. Residual volumes after removal of the catheter were measured by ultrasound scanning. Where residual volumes of >200 mL were found the patient was recatheterised for three more days. Urinary cultures were taken before removal of the catheter. Six patients were excluded: four in the standard prolonged catheterisation group and two in the not prolonged catheterisation group. Main outcome measures Need for recatheterisation, urinary tract infection, mean duration of catheterisation and hospital stay. Results Residual volumes exceeding 200 mL and need for recatheterisation occurred in 9% in the standard prolonged catheterisation group versus 40% of patients in the not prolonged catheterisation group (OR 0.15, 95% CI 0.045 -0.47). Positive urine cultures were found in 40% of cases in the standard prolonged catheterisation group compared with 4% in the not prolonged catheterisation group (OR 15, 95% CI 3.2 -68.6). Mean duration of catheterisation was 5.3 days in the standard prolonged catheterisation group and 2.3 days in the not prolonged catheterisation group (P < 0.001). Mean duration of hospitalisation was 7 days in the standard prolonged catheterisation group and 5.7 days in the not prolonged group (P < 0.001). Conclusion The disadvantages of prolonged catheterisation outweigh the advantages, therefore, removal of the catheter on the morning after surgery may be preferable and longer term catheterisation should only be undertaken where there are specific indications.
Urinary retention after vaginal prolapse surgery occurs more frequently in women with larger cystoceles, severe intra-operative blood loss and the application of levator plication and Kelly plication.
Introduction and hypothesisPostpartum urinary retention (PUR) is a common consequence of bladder dysfunction after vaginal delivery. Patients with covert PUR are able to void spontaneously but have a postvoid residual bladder volume (PVRV) of ≥150 mL. Incomplete bladder emptying may predispose to bladder dysfunction at a later stage of life. The aim of this cross-sectional study was to identify independent delivery-related risk factors for covert PUR after vaginal delivery in order to identify women with an increased risk of covert PUR.MethodsThe PVRV of women who delivered vaginally was measured after the first spontaneous micturition with a portable bladder-scanning device. A PVRV of 150 mL or more was defined as covert PUR. Independent risk factors for covert PUR were identified in multivariate regression analysis.ResultsOf 745 included women, 347 (47 %) were diagnosed with covert PUR (PVRV ≥150 mL), of whom 197 (26 %) had a PVRV ≥250 mL (75th percentile) and 50 (7 %) a PVRV ≥500 mL (95th percentile). In multivariate regression analysis, episiotomy (OR 1.7, 95 % CI 1.02 – 2.71), epidural analgesia (OR 2.08, 95 % CI 1.36 – 3.19) and birth weight (OR 1.03, 95 % CI 1.01 – 1.06) were independent risk factors for covert PUR. Opioid analgesia during labour (OR 3.19, 95 % CI 1.46 – 6.98), epidural analgesia (OR 3.54, 95 % CI 1.64 – 7.64) and episiotomy (OR 3.72, 95 % CI 1.71 – 8.08) were risk factors for PVRV ≥500 mL.ConclusionsEpisiotomy, epidural analgesia and birth weight are risk factors for covert PUR. We suggest that the current cut-off values for covert PUR should be reevaluated when data on the clinical consequences of abnormal PVRV become available.
