Bladder catheterization improves bacterial interference with asymptomatic Escherichia coli 83972 in an experimental porcine model of urinary tract infection.

BACKGROUND: Urinary tract infection (UTI) is a common disease with a significant risk of relapse. Deliberate bladder colonization with asymptomatic Escherichia coli is being explored as a potential strategy to fend off invading uropathogens thereby mitigating the risk symptomatic UTI. Currently, one major obstacle is the low success rates for achieving persistent bladder colonization with asymptomatic bacteria and experimental challenge studies are lacking. Here, we assessed the influence of an indwelling bladder catheter on the ability of asymptomatic E. coli to colonize the bladder and to assess the protective efficacy of such colonization against experimental urinary tract infection with uropathogenic E. coli. METHODS: Pigs with or without indwelling bladder catheters were experimentally inoculated with the asymptomatic E. coli strain 83972 and subsequently challenged by inoculation with the uropathogenic E. coli isolate, UTI89. The animals were monitored with regular urine and blood samples and bladders and kidneys were harvested at termination. RESULTS: All pigs with indwelling catheters were colonized by 83972 in response to inoculation, compared to pigs without catheters in which only one of eight animals were colonized. When removing the catheter, 83972 were spontaneously cleared. Colonization with 83972 prevented experimental infection in 50% of animals compared to controls that all became infected. CONCLUSIONS: The presence of indwelling bladder catheters strongly facilitates the colonization of 83972, indicating that individuals using catheters may be particularly suited for receiving this treatment. The research supports prophylactic colonization with 83972 as a potential strategy to reduce the risk of urinary tract infections.

Ascending renal infection following experimental candiduria by Candida tropicalis in immunocompromised mice.

The present study evaluated renal infection resulting from the implantation of C. tropicalis in the bladder of immunosuppressed mice. Yeasts were implanted in two manners: planktonic and via preformed biofilm on a small catheter fragment (SCF). Renal histopathology and cultures was performed 72 and 144 h after cystotomy was carried out in mice from three groups: group I contained non-contaminated mice implanted with a sterile SCF; group II mice received a sterile SCF plus a yeast suspension containing 1 × 107 yeasts/mL in a planktonic form; group III mice were implanted with a SCF containing preformed C. tropicalis biofilm. Viable yeasts were found in the kidneys of mice from both groups II and III. However, after 72 h the planktonic cells (group II) invaded more quickly than the sessile cells (group III). Over a longer period (144 h), group III exhibited a more invasive infection (50% of the animals presented renal infection and the renal fungal load was 3.2 log10 CFU/g tissue) than in group II, where yeasts were not found. C. tropicalis introduced into the bladder in two ways (in planktonic or biofilm form) were able to reach the kidney and establish a renal fungal infection, causing interstitial disorders. The data of the present study therefore support the hypothesis of an ascending pathway for renal infections by C. tropicalis. Furthermore, the biofilm resulted in a greater and progressive risk of renal infection, attributed to the slow detachment of the yeasts.

Multicentre, prospective, randomized control non-inferiority trial of bladder catheter management in colon surgery.

AIM: Perioperative bladder catheterization is a controversial issue. Most current recommendations are based on data from open surgery extrapolated to enhanced recovery after surgery or fast-track programmes ranging between 24 and 48 h. The aim of this study is to provide a rationale for reducing catheterization time while at the same time avoiding acute urine retention (AUR), in patients undergoing scheduled laparoscopic colon surgery. METHOD: This is a multicentre, prospective, controlled, randomized non-inferiority study of bladder catheter management in patients undergoing scheduled laparoscopic colon surgery, randomized into two groups: experimental (with catheter removal immediately after surgery) and control (with catheter removal 24 h post-surgery). The main outcome will be the development of AUR, and secondary outcomes the development of urinary infection within the first 30 days and hospital stay. Demographic, surgical and pathological variables will also be evaluated, especially the development of adverse effects assessed according to the Clavien scale and the Comprehensive Complication Index. Following the literature, we assume an incidence of AUR of 11% and a margin of non-inferiority (delta) of 8% and estimate that a sample size of 208 patients per group will be required (with an estimated 10% of losses per group). CONCLUSIONS: In this study we try to demonstrate that the bladder catheter can be removed immediately after scheduled laparoscopic colon surgery, without increasing acute urine retention. This measure would offers the benefits of earlier mobilization and reduces catheter-related morbidity.

Analysis of purple urine bag syndrome by low vacuum scanning electron microscopy.

Purple urine bag syndrome (PUBS) is seen in the prolonged indwelling bladder catheters, and the mechanism of its onset was investigated using low vacuum scanning electron microscopy (LVSEM), which enables us to study the 3D structure of urinary sediments and urine bag walls. The urinary sediment and urine bags of 2 cases of PUBS were observed by LVSEM. The urine was brown turbid urine with a pH of 8.5, and magnesium phosphate stones and granules were observed in the urinary sediment together with Gram-positive and Gram-negative bacilli. Bacteria that moved by Brownian motion were observed with a dark-field microscope. LVSEM showed granular crystals around the bacilli, cocci, or mycelium that adhered to the walls of the bag. Granular crystals were dissolved in chloroform and presumed to be a mixture of the bacterial metabolites indigo blue and indirubin red. LVSEM also detected unusual tubular and honeycomb-like graphene in the urinary sediments, which were derived from the inner layer of the silicon elastomer-coated rubber catheter. LVSEM revealed purple crystals produced by bacteria or fungi attached to the urine bag that caused PUBS.

Evaluation of Strategies to Prevent Urinary Tract Injury in Minimally Invasive Gynecologic Surgery: A Systematic Review.

OBJECTIVE: To systematically review tools for the prevention of urinary tract injury in adult women undergoing minimally invasive gynecologic surgery. DATA SOURCES: A medical librarian (M.P.H.) searched Ovid Medline 1946 to, Ovid Embase 1929 to, CINAHL 1965 to, Cochrane Library 1974 to, Web of Science 1926 to, and SCOPUS 1974 to present on April 2 and April 3, 2020. METHODS OF STUDY SELECTION: Articles evaluating strategies for the prevention of urinary tract injury at the time of minimally invasive gynecologic surgery were included. Articles that were nongynecologic, nonhuman, and nonadult were excluded. If a study did not describe the surgical approach or type of surgical procedures performed, it was excluded. If the study population was <50% gynecologic or <50% minimally invasive, it was excluded. Articles evaluating techniques for the diagnosis or management of injury, rather than prevention, were excluded. TABULATION, INTEGRATION, AND RESULTS: The search yielded 2344 citations; duplicates were removed, inclusion criteria were applied, and 9 studies remained for analysis. Three studies evaluated bladder catheters, and 6 evaluated ureteral catheters. In the 3 studies evaluating bladder catheters, there were no urinary tract injuries. Urinary tract infection was greater in women who received a bladder catheter. In the studies evaluating the use of ureteral catheters, we found inconsistent reporting and heterogeneity that precluded meta-analysis. The results of the available studies do not indicate that ureteral catheters decrease the risk of injury, and indicate that they increase morbidity. CONCLUSION: The evidence is insufficient to support the routine use of bladder catheters or ureteral catheters for the prevention of urinary tract injury at the time of minimally invasive gynecologic surgery.

Incidence and Severity of Catheter-Related Bladder Discomfort Among Nonurological Adult Patients in a Postanesthesia Care Unit.

PURPOSE: The purpose of this study was to identify the incidence and severity of catheter-related bladder discomfort (CRBD) among nonurological adult patients in a postanesthesia care unit with catheter sizes of 10 to 18 Fr. DESIGN: Descriptive, prospective, and quantitative study. METHODS: In all, 401 patients were included. Incidence and severity of CRBD were assessed upon arrival and 1 hour after arrival. FINDINGS: CRBD incidence was 17.2% (n = 69) on arrival versus 19.1 (n = 74) 1 hour after arrival. Male gender showed a significantly higher risk of developing CRBD upon arrival (odds ratio, 3.15; P = .000; 95% confidence interval, 1.78 to 5.59), and 1 hour after arrival (odds ratio, 2.34; P = .002; 95% confidence interval, 1.38 to 3.99). CONCLUSIONS: The findings suggest using a catheter as small as possible and confirm that men experience significantly more discomfort, whatever sized catheter is used.

[Epidemiology of emergency consultations for acute urine retention]. / Épidémiologie des consultations aux urgences pour une retention aiguë d'urine.

INTRODUCTION: Acute urinary retention (AUR) is a common reason for emergency consultation. It may be spontaneous or precipitated and affects both men and women. The purpose of this study was to determine the profile of men visiting emergency departments for an AUR. MATERIEL AND METHODS: A retrospective monocentric study including all men who consulted the emergency department between January 2014 and December 2016 for AUR was conducted. RESULTS: In 3 years, 731 patients were admitted for AUR (611 men and 120 women). The mean age was 71.6±14 years with a mean retention volume of 948±668mL drained for 96% of patients (n=584) through a bladder catheter and 4% (n=27) with a suprapubic catheter. Most patients had an urological (66%, n=104) or neurologic (40%, n=242) history and 23% (n=136) already had an episode of AUR. In 28% of cases (n=173), the globe was not painful. A majority of AUR were spontaneous, 53% (n=326) versus 46% (n=279) who were precipitated, secondary to a recent surgical procedure (<1 month) (15%, n=89), hematuria (9%, n=54), or male urinary tract infections (7%, n=42). Patients were treated externally in 71% (n=436), 25% (n=153) were hospitalized with significantly more comorbidities. CONCLUSION: Men consulting emergency for AUR are 72 years old, with a globe volume of 942mL. Thirty-three percent have a history of BPH, with a prostate treatment like alpha-blockers type. Almost all patients were treated with a bladder catheter and the majority was treated externally. LEVEL OF EVIDENCE: 4.

[Obstructive pyelonephritis caused by ureteral orifice catheterization with a bladder catheter]. / Pyélonéphrite obstructive par cathétérisation du méat urétéral par une sonde vésicale.

This article reports a rare case of acute pyelonephritis secondary to left ureteral obstruction by a bladder catheter. The patient was 93years old man hospitalized in the hospital emergency department with a 39°C fever and pyuria from an indwelling catheter. Blood test found hyperleukocytosis, inflammatory syndrome and acute renal failure. Diagnosis was confirmed by non-contrast abdominal CT scan showing distal part of the catheter inside left ureteral orifice with ureterohydronephrosis. Treatment consisted in replacing the catheter by a three-way catheter for irrigation and parenteral antibiotics therapy. Clinico-biological evolution was successful and a urinary tract CT scan could be realized at day 9. The left upper urinary tract function was recovered. With a short review of the literature we propose to describe the different procedures to manage those obstructions.

Experience sharing of conservative treatment after a 90-year-old male replacing the suprapubic bladder catheter enters the small intestine: A rare case report.

INTRODUCTION: The treatment of intestinal perforation caused by the SBC enters the small intestine in elderly patients is a challenge for urologists. The report is to share our experience of conservative treatment after a 90-year-old male with the suprapubic bladder catheter enters the small intestine. PRESENTATION OF CASE: Because of the device was obstructed, a 90-year-old male went to our hospital with his family and requested to replace the SBC. When the fistula tube was replaced, it entered the intestine through the intestinal injury site instead of entering the bladder. During the hospitalization, the patient was given supportive treatments and the SBC was dynamically monitored daily and it was intermittently withdrawn out during this period. After the drainage volume was less than 10 mL for three consecutive days and the intestinal fistula was healing gradually, the catheter was taken out. DISCUSSION: According to our experience, the common complications in the process include failure to pull out the SBC, abnormal position of the SBC, and poor drainage of the SBC. However, the drainage tube placing into the small intestine through the original hole of the suprapubic bladder fistula during the replacement process is quite rare. When elderly patients have traumatic small bowel perforation, the diagnosis and treatment of intestinal perforation in elderly patients was particularly important. CONCLUSION: The conservative treatment of intestinal perforation is suitable for elderly patients who are unsuitable or unwilling to undergo a surgical operation. Of course, it should be in accordance with the patient's condition to make the right choice of treatment.

Association of acute urinary retention in postoperative patients with a urinary catheter, with and without bladder catheter clamping. / Asociación de retención urinaria aguda en pacientes postoperados con catéter urinario, con y sin pinzamiento de catéter vesical.

INTRODUCTION: The use of a temporaryor permanent catheter is very common in clinical practice. Between 15.0% and 25.0% of hospitalized patients have in-dwelling bladder catheters, the majority of which are short-term. Bladder catheter clamping before catheter removal was generally regarded as useful in the past. Today, its utility is questionable. OBJECTIVE: To determine the association between bladder catheter clamping and spontaneous micturition or acute urinary retention (AUR) in postoperative patients with short-term indwelling bladder catheter. MATERIALS AND METHODS: A descriptive, comparative,longitudinal study was conducted at a secondary care hospital center in a western Mexican state .AUR was the outcome variable. Two study groups wereformed: patients with bladder catheter clamping (n=43) and the control patients with no bladder catheter clamping (n=41). Descriptive statistical analyses were performed, and percentage comparisons were made with the chi-squaretest. Significant predictors were subsequently added to the multivariate model. RESULTS: Fourteen percent (n=12) of all the study patients, with and without bladder catheter clamping, presented with AUR and 86% (n=72) did not. In the association analysis, there was no statistically significant difference between presenting with AUR and having or not having bladder catheter clamping (p=0.59). The associations of AUR with bladder re-catheterization (p=0.001), age (p=0.01), and the presence of lower urinary symptoms (p= 0.005) were statistically significant. CONCLUSION: Postoperative bladder catheter clamping was not associated with the presence of AUR.

INTRODUCCIÓN: El uso de un catéter urinario temporal o permanente es muy común en la práctica clínica. Entre el 15,0% y el 25,0% de los pacientes hospitalizados tienen catéteres vesicales, la mayoría a corto plazo. Durante mucho tiempo se había considerado a los ejercicios vesicales como una práctica útil antes del retiro de los mismos. En la actualidad su utilidad es muy cuestionable.OBJETIVOS: Determinar la asociación que tienen los ejercicios vesicales sobre la micción espontánea o retención aguda de orina en pacientes postoperados portadores de catéter urinario de corta duración.MATERIAL Y MÉTODOS: Se realizó un estudio comparativo, longitudinal y descriptivo en un hospital de 2º nivel de un estado de occidente de México. La variablede desenlace fue la retención aguda de orina. Se formaron dos grupos de estudio; con ejercicios vesicales y un grupo control sin ejercicios vesicales 43 sujetos vs- 41 respectivamente. Se realizaron pruebas estadísticas descriptivas y a comparación de porcentajes se realizó con la prueba Chi2. Posteriormente se agregaron predictores significativos al modelo multivariable.RESULTADOS: De los pacientes incluidos en el estudio con y sin ejercicios vesicales, 14% (12) presentaron retención aguda de orina (RAO) y 72% (86) no la presentaron. Haciendo un análisis de asociación, no hubo significancia estadística, tener RAO y hacer ejercicios vesicales o no hacerlos (p=0,59). Hubo asociación estadísticamente significativa cuando se compararon la recolocación del catéter urinario con RAO p=0,001, la edad con la RAO p=0,01 y la presencia de síntomas irritativos urinarios bajos p=0,005.CONCLUSIÓN: El realizar ejercicios vesicales en los pacientes postoperados no están asociados a la presencia de retención aguda de orina.

Avoiding Bladder Catheters During Atrial Fibrillation Ablation.

OBJECTIVES: This study sought to determine if atrial fibrillation (AF) ablation can be performed safely without bladder catheterization. BACKGROUND: Patients undergoing AF ablation often receive bladder catheters. Catheterization is associated with potential complications. The ABCD-AF (Avoiding Bladder Catheters During Atrial Fibrillation) ablation study evaluates the advantages of performing AF ablation without routine catheterization. METHODS: In this single-center, prospective, randomized controlled trial, 80 patients received bladder catheterization (group A), and 80 patients received only as-needed catheterization (group B). The primary endpoint was a composite of cystitis, urethral injury, hematuria, dysuria, or urinary retention. RESULTS: The mean patient age was 63 ± 13 years, and 33% of patients were female. The primary outcome was reached in 45 patients in group A and 11 patients in group B (p < 0.001). Urinary tract infection occurred in 7 patients in group A and 2 patients in group B (p = 0.17). Urinary retention occurred in 12 patients in group A and 5 patients in group B (p = 0.07). Randomization to catheterization carried an odds ratio of 8.1 (95% confidence interval [CI]: 3.7 to 17.5; p < 0.001), and male sex carried an odds ratio of 3.8 (95% CI: 1.7 to 8.6; p = 0.001) for the primary endpoint. On subgroup analysis, randomization to undergo catheterization had no association with the primary outcome in female patients but had an odds ratio of 14.6 (95% CI: 5.6 to 38.1; p < 0.001) in male patients. In multivariable analysis, sex and catheter status remained independently associated with the primary outcome. CONCLUSIONS: Bladder catheterization can be safely avoided in patients undergoing AF ablation and is associated with a significant reduction in adverse outcomes, especially in men.

Avoiding Urinary Catheterization in Patients Undergoing Atrial Fibrillation Catheter Ablation.

PURPOSE: Indwelling urinary catheters are commonly inserted when administering general anesthesia. However, there are significant risks to routine IUC insertion. We compared urinary and other outcomes in a population of patients undergoing atrial fibrillation (AF) ablation with or without IUC. METHODS: This was a single center, retrospective review of patients undergoing AF ablation. Patients were identified by procedure codes and patient health characteristics and outcome data were manually extracted from electronic health records. The primary composite endpoint was 7-day periprocedural urinary outcomes including cystitis, dysuria, hematuria, urethral damage, or urinary retention. RESULTS: 404 patients were included in the study, 297 with IUC and 107 without IUC. Uncatheterized patients were less likely to have congestive heart failure (CHF) (31.8% vs 43.4%; P = 0.039) and had a shorter procedure length (4.2 vs 4.9 hours; P < 0.001) with less fluid administered (1485 vs 2040 mL; P < 0.001). No urinary complications occurred in the uncatheterized group versus 14 in the catheterized group (P = 0.026). 3 patients in the uncatheterized group developed serious infections versus none in the catheterized group (P = 0.018). There was no incidence of death and no statistically significant difference in readmission in the 30 days after procedure. CONCLUSIONS: There were no urinary complications in 107 patients who received no IUC during AF ablation. Avoiding bladder catheters during AF ablation procedures may lower incidence of adverse urinary complications without adding substantial risk of urinary retention.

Vesicoureteral antireflux surgery with Lich-Gregoir technique without vesical drainage: Long-term results. / Resultados a largo plazo de cirugía antirreflujo vesicoureteral con técnica de Lich-Gregoir sin drenaje vesical.

OBJECTIVE: To describe our long-term experience with patients with vesicoureteral reflux (VUR) who underwent conventional surgery without postoperative bladder drainage. MATERIAL AND METHODS: Retrospective review of 45 patients surgically treated by extravesical Lich-Gregoir's ureterovesical reimplantation without postoperative bladder drainage between 2010 and 2013. RESULTS: 37 women (82.2%) and 8 men (17.8%). 28 patients with unilateral reflux, and 17 patients with bilateral reflux with a total of 62 operated kidneys. The mean age at surgery was 6 years (2 to 11 years). The main cause of surgical indication was the persistence of reflux in patients older than 6 years (73.3%); with grade III VUR (75.6%) being the most frequent. The mean surgical time was 44minutes (35-70) for unilateral reimplantation, and 70minutes (53-98) for bilateral ones. All patients presented spontaneous urination in the immediate postoperative period, without pain, no hematuria, full incontinence, and without a bladder balloon. None required bladder catheter placement, and hospital discharge was indicated between 7 and 36hours postoperatively (mean 11h). All continued with spontaneous micturitions, without postvoid residual or voiding dysfunction during the 5-year follow-up. CONCLUSION: The thorough selection of the patients, the detailed surgical gestures, the bladder emptying without instrumentation of the urethra, together with a correct use of analgesics and early ambulation allowed excellent outcomes obtained in these patients managed with a short hospital stay and without bladder drainage, also demonstrating the safety of the procedure at 5 years of follow-up.

Urinary infection in the elderly. / Infección urinaria en el anciano.

INTRODUCTION: Urinary tract infections (UTIs) are one of the most frequent infections. In the elderly, they have multiple comorbidities. The objective of this work is to describe the clinical and microbiological epidemiology of elderly persons admitted for UTIs and to evaluate the suitability of empirical treatments and their implications regarding mortality. MATERIAL AND METHODS: An observational study was conducted during 2013-2015 in 4public hospitals, with patients older than 65 years who were admitted to the Internal Medicine service with a microbiological diagnosis of UTI. Cases of asymptomatic bacteriuria were excluded. In-hospital mortality was analyzed. Univariate analysis and multivariate analysis was carried out. RESULTS: A total of 349 episodes were selected, with a mean age of 82 ± 11 years, 51% female. Mortality was 10.3% and was associated with age, dementia and sepsis and septic shock (P<.05). The most frequent organisms were Escherichia coli(E. coli) (53.6%), Klebsiella spp. (8.7%) and Enterococcus spp. (6.6%). E. coli and Klebsiella spp. with extended-spectrum beta-lactamases (13% of the total isolated) were associated with the previous use of antibiotics, community care treatment and a permanent urinary catheter (P<.05). The empirical treatment was adequate only in 73.6% of cases. As these treatments were associated with higher mortality, they were not considered adequate. CONCLUSIONS: In the elderly, UTIs show a high mortality. Empirical treatment is often inadequate and may be associated with increased mortality.

Sonication as a tool for disrupting biofilms and recovering microorganisms in bladder catheters / Sonicação como uma ferramenta para romper biofilmes e recuperar microrganismos em cateteres vesicais

Abstract Introduction: Urinary catheter-related infection is commonly associated with bacterial biofilm. The impact of anaerobes is unknown, but their detection in the biofilm on this device has not been previously reported. This study aimed to evaluate the capability to recovery strict, facultative, and aerobic microorganisms in patients using bladder catheters from ICUs using conventional culture, sonication, urinary analysis, and mass spectrometry. Methods: Parallel, sonicated bladder catheters from 29 critically ill patients were compared with their routine urine culture. Identification was performed using matrix-assisted laser desorption/ionization with time-of-flight mass spectrometry. Results: The positivity rate in urine (n = 2, 3.4%) was lower than that in sonicated catheters (n = 7, 13.8%). Conclusion: Bladder catheter sonication showed more positive culture results than urine samples for anaerobic and aerobic microorganisms. The role of anaerobes in urinary tract infection and catheter biofilm is discussed.

Resumo Introdução: A infecção relacionada ao cateter urinário é comumente associada ao biofilme bacteriano. O impacto dos anaeróbios é desconhecido, mas sua detecção no biofilme deste dispositivo não foi relatada anteriormente. Este estudo teve como objetivo avaliar a capacidade de recuperar microrganismos estritos, facultativos e aeróbios em pacientes que utilizam cateteres vesicais de UTIs utilizando cultura convencional, sonicação, análise urinária e espectrometria de massa. Métodos: Paralelamente, foram comparados cateteres vesicais sonicados de 29 pacientes gravemente enfermos com sua urocultura de rotina. A identificação foi realizada utilizando dessorção/ionização a laser assistida por matriz com espectrometria de massa por tempo de voo. Resultados: A taxa de positividade na urina (n = 2; 3,4%) foi inferior à dos cateteres sonicados (n = 7; 13,8%). Conclusão: A sonicação do cateter vesical apresentou resultados de cultura mais positivos do que as amostras de urina para microrganismos anaeróbios e aeróbios. É discutido o papel dos anaeróbios na infecção do trato urinário e no biofilme do cateter.

Enhanced recovery after gastro-intestinal surgery: The scientific background.

Enhanced recovery programs (ERP) are without any doubt a major innovation in the care of surgical patients. This multimodal approach encompasses elements of both medical and surgical care. The goal of this in-depth review is to analyze the surgical aspects of ERP, underlining the scientific rationale behind each element of ERP after surgery and in particular, the role of mechanical bowel preparation before colorectal surgery, the place of minimal access surgery, the utility of nasogastric tube, abdominal drainage, bladder catheters and early re-feeding. Publication of factual data has allowed many dogmas to be discarded.

[Post-partum management after cesarean delivery. Guidelines for clinical practice]. / Césarienne et post-partum. Recommandations pour la pratique clinique.

OBJECTIVE: To determine guidelines for post-partum management after cesarean delivery regarding patient monitoring, organization, postoperative analgesia, time of urinary catheter removal, resumption of feeding and drinking, timing of ambulation, indication and modalities of thromboprophylaxis. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Immediate postoperative monitoring after caesarean delivery should be performed in the recovery room, but in exceptional circumstances, it may be performed in the delivery unit provided safety rules are maintained and regulatory authorities are informed (professional consensus). Specific surveillance including emergency call procedures must be performed (professional consensus). Systematic blood count performed immediately after cesarean delivery is not recommended in the general population (professional consensus). An analgesic protocol developed by the medical team should be available for each patient (professional consensus). An indwelling bladder catheter should be inserted before and maintained during surgery (professional consensus). The bladder catheter should be preferentially removed in the first 12 hours after cesarean delivery (professional consensus). It is recommended to check that spontaneous voiding has occurred in the 4-6 hours after the removal of the bladder catheter. The physician in charge should be alerted if the patient has failed to void within 6 hours after catheter removal (grade C). Early ambulation on day 1 (or earlier from the 6th to 8th hour) with help is advised and encouraged (professional consensus). Early feeding and drinking after elective or emergency cesarean delivery, performed under regional or general anesthesia, is recommended (grade A). Administration of a prophylactic treatment using two antiemetic medications is recommended during cesarean delivery (grade B). For every cesarean delivery, thromboprophylaxis with elastic stockings applied on the morning of the surgery and kept for at least 7 postoperative days is recommended (professional consensus) with or without the addition of LMWH according to the presence or not of additional risk factors, and depending on the risk factor (major, minor). In obese patient, LMWH dose needs to be weight-adapted (grade C). CONCLUSION: Harmonization of care according to these recommendations is expected to enhance recovery after cesarean delivery.

A prospective randomized controlled comparison of immediate versus late removal of urinary catheter after abdominal hysterectomy.

OBJECTIVE: Indwelling transurethral catheter is frequently used after gynecological surgeries in order to prevent urinary retention. There is controversy about the ideal time to remove the catheter after surgery. This randomized controlled study was undertaken to determine whether the immediate removal of urinary catheter after abdominal hysterectomy affects the rate of symptomatic urinary tract infection (UTI), recatheterization, subjective pain perception and febrile morbidity. STUDY DESIGN: This prospective randomized controlled trial included 70 women undergoing abdominal hysterectomy with or without salpingoophrectomy for benign diseases. Patients were divided into two equal groups on the basis of timing of removal of urinary catheter (Group I - Immediate removal after surgery, Group II - Removal after 24 h and evaluated for benefits versus risks of immediate catheter removal. The results were compared by the Chi-square test. RESULTS: Recatheterization was required in three patients of immediate removal group and none in late removal group (P = 0.07). Higher incidence of positive urine cultures (25.9%) and febrile morbidity (10%) was found in Group II when compared to immediate removal group (8%). Pain perception was not statistically different in both groups (P = 0.567). CONCLUSIONS: The early removal of an indwelling catheter after surgery was not associated with an increased rate of febrile events, UTI. Pain perception was also lower in early removal group. Although need of recatheterization was higher in early removal group, but not statistically significant.

What we don't know may hurt us: urinary drainage system tubing coils and CA-UTIs-A prospective quality study.

Catheter-associated urinary tract infections account for >30% of infections in acute care hospitals. We hypothesized that coiling of/kinks in the indwelling urinary bladder catheter (IUBC) drainage bag tubing would increase the occurrence of infection/bacteriuria. Ninety-one patient events were evaluated over 60 days. All outcome variables trended with greater frequency among those with a coil in the IUBC tubing; only fever (temperature > 38.1°C) correlated significantly between groups (P = .003). If IUBC is unavoidable, strategies such as keeping collection bag below the level of bladder and avoiding any coiling in the drainage system should be employed. Further study of these phenomena is needed.
