Point-of-care abdominal ultrasound in pediatric and neonatal intensive care units.

A spectrum of critical abdominal pathological conditions that might occur in neonates and children warrants real-time point-of-care abdominal ultrasound (abdominal POCUS) assessment. Abdominal radiographs have limited value with low sensitivity and specificity in many cases and have no value in assessing abdominal organ perfusion and microcirculation (Rehan et al. in Clin Pediatr (Phila) 38(11):637-643, 1999). The advantages of abdominal POCUS include that it is non-invasive, easily available, can provide information in real-time, and can guide therapeutic intervention (such as paracentesis and urinary bladder catheterization), making it a crucial tool for use in pediatric and neonatal abdominal emergencies (Martínez Biarge et al. in J Perinat Med 32(2):190-194, 2004) and (Alexander et al. in Arch Dis Child Fetal Neonatal Ed 106(1):F96-103, 2021). Conclusion: Abdominal POCUS is a dynamic assessment with many ultrasound markers of gut injury by two dimensions (2-D) and color Doppler (CD) compared to the abdominal X-ray; the current evidence supports the superiority of abdominal POCUS over an abdominal X-ray in emergency situations. However, it should still be considered an adjunct rather than replacing abdominal X-rays due to its limitations and operator constraints (Alexander et al. in Arch Dis Child Fetal Neonatal Ed 106(1):F96-103, 2021). What is Known: • Ultrasound is an important modality for the assessment of abdominal pathologies. What is New: • The evidence supports the superiority of abdominal POCUS over an abdominal X-ray in emergency abdominal situations in the neonatal and pediatric intensive care units.

Urinary bladder catheterisation of female pigs: Influence of bladder content and Escherichia coli urinary tract infection on procedural outcome.

Catheterisation of the urinary bladder is needed in many types of human disease models in pigs. Based on our extensive experience with the pig as an infection model, we here demonstrate an approach of catheterising domestic pigs (40 attempts) and Göttingen minipigs (10 attempts) using a blinded method, that is, without speculums or videoscopes to visualise the urethral opening. The procedure was tested on control animals and pigs with experimental Escherichia coli urinary tract infection (UTI) to assess the potential influence of this condition on procedural outcome. Lastly, we performed cystoscopy in three animals to visualise the route to the urethra and to localise potential anatomical obstacles. All domestic pigs were catheterised successfully in an average of 2 minutes and 23 seconds, and this was not influenced by UTI (p = 0.06) or bladder urine content at the time of catheterisation (p = 0.32). All Göttingen minipigs were successfully catheterised in an average of 4 minutes and 27 seconds. We conclude that blinded catheterisation is a fast and reliable approach that can be performed in pigs with or without UTI with minimal risk of trauma or contamination.

Abdominal Wall Movements Predict Intra-Abdominal Pressure Changes in Rats: A Novel Non-Invasive Intra-Abdominal Pressure Detection Method.

(1) Background: As increases in intra-abdominal pressure (IAP) result in irreversible tissue damage, monitoring IAP in critically ill patients using the common urinary bladder catheter method is essential. However, this method can result in complications and is not suitable for very low birth weight neonates. The aim of this study was to establish a non-invasive and accurate method to detect IAP changes using an animal model. (2) Methods: IAP changes via intra-abdominal air application (up to 20 mmHg) were measured in 19 Wistar rats via an intra-abdominally placed intracranial pressure probe. Concurrently, abdominal surface tension was measured using a Graseby capsule (GC). (3) Results: A high correlation between abdominal wall distension and IAP (r = 0.9264, CI 0.9249-0.9279) was found for all subjects. (4) Conclusions: IAP changes in rats can be detected non-invasively using a GC. However, further studies are necessary to assess whether IAP changes can be measured using a GC in the neonatal population.

#5095 THE CURIOUS CASE OF GAS IN THE GRAFT KIDNEY

Abstract Background and Aims Emphysematous pyelonephritis (EPN) denotes a severe infection of renal parenchyma resulting in necrosis and gas accumulation in the renal and perirenal tissue. Risk factors for urinary tract infections in renal transplant recipients include advanced age, female gender, reflux nephropathy prior to transplantation, diabetes mellitus, deceased donor kidney, kidney–pancreas transplant, retransplantation, antibody induction for immunosuppression, urinary bladder catheterisation, history of allograft rejection with subsequent escalation of immunosuppressive therapy and use of ureteral stents. There are no definite guidelines for management of EPN in renal allografts. If unstable and deteriorating, graft nephrectomy should be undertaken as soon as possible. Any delay in surgical intervention, be it percutaneous drainage or nephrectomy may result in death. Method A 25-year old male, diagnosed with IgA Nephropathy (IgAN) received a living donor renal transplant from his mother in 2013 after a dialysis vintage of 3 years. He received Basiliximab induction followed by maintenance immunosuppression with Tacrolimus, Mycophenolate mofetil and Prednisolone. He had no history of UTI in the immediate post-transplant period. His blood glucose levels were within normal limits and he had not had any urological intervention. In 2019, patient was diagnosed with IgAN recurrence as a cause of chronic renal allograft injury. His Creatinine at last follow up in July 2022 was 4.1 mg/dL. He presented in September 2022 with fever, chills, vomiting, pain in the right iliac fossa and inability to extend his right leg. At presentation, his BP was 86/60mmHg, with pyrexia and tachycardia. Ultrasonography revealed an ill-defined collection superomedial to the graft kidney with doubtful posterior extension and air foci. Non-contrast CT study revealed a large subcapsular collection, extending posteriorly into the right iliac fossa involving the right psoas major and inferiorly into the pelvis, with air foci and no evidence of any urinary tract obstruction suggestive of Acute Emphysematous pyelonephritis with ruptured abscess. He was started on broad-spectrum iv antibiotics- Meropenem and Levofloxacin. Immunosuppression was reduced. Laboratory investigations revealed total leucocyte count of 37,000 cells/mm3, Creatinine of 11 mg/dL, urine routine microscopy revealed field full of pus cells. Blood and urine cultures grew ESBL Escherichia coli. He was taken up for urgent urological intervention in the form of percutaneous drain insertion. Frank pus was aspirated and 200mL drained instantaneously, cultures of which demonstrated the same organism. Within 24 hours of pus drainage, patient became afebrile and had pain relief. He was given 3 weeks of culture-appropriate iv antibiotics, to continue another 3 weeks of oral Carbapenem. However, his graft dysfunction persisted, with no recovery and he became dialysis-dependent. Discussion EPN of the renal allograft is a rare occurrence. A study of EPN in renal transplant recipients by Alexander et al from 2012 revealed 18 out of 22 patients were diabetics, 9 necessitated graft nephrectomy and 7 required percutaneous drainage in addition to antibiotics4. Till date, up to 30 cases of graft EPN have been reported in English literature. The striking feature is that more than 90% of these cases were diabetic. Conclusion The complete pathogenesis of renal allograft EPN, especially in patients with no apparent traditionally described risk factors remains yet to be understood. A high degree of suspicion and early intervention may help to save the allograft.

Invasive urothelial carcinoma with squamous differentiation and associated high-risk human papilloma virus infection: Clinical, cytologic, and histologic features of a rare entity

We correlate the fine needle aspiration (FNA) cytologic findings with the histologic features of an invasive high-grade urothelial carcinoma showing squamous differentiation in the setting of high-risk Human Papilloma Virus (hrHPV) infection. To our knowledge, only extensive urinary bladder catheterization has been associated with hrHPV-positive urothelial carcinoma with squamous differentiation, and rarely at that. Herein, we present a case arising in a patient with only sparse and intermittent catheterization. A 69-year-old woman presented with voiding difficulties, and after continued symptoms, a Foley catheter was placed, and a cystoscopy procedure revealed two 1–2 cm inflammatory masses. Excisional biopsies were interpreted as papillary urothelial carcinoma. One month follow-up pelvic imaging demonstrated a new mass involving the urinary bladder neck, with irregular wall thickening and perivesical fat stranding, as well as probable vaginal involvement. CT-guided FNA (CT-FNA) to collect smears and core biopsies revealed an invasive urothelial carcinoma with squamous differentiation. HPV-cytopathic changes amid squamous metaplasia and dysplasia were noted on FNA smears with HPV E6/E7 RNA in situ hybridization (ISH) showing on the FNA core biopsy specimen. Immunostains showed that the tumor cells were positive for P16 (strong, diffuse), CK7, p63, ER, and GATA3 (patchy). Subsequent radical cystectomy revealed the extent of the patient's carcinoma, with direct extension to the vaginal wall, and involvement of the radial soft tissue resection margins. Describing the cytomorphologic features of a hrHPV positive urothelial carcinoma with squamous differentiation, without an extensive history of urinary catheterization or prior known history of HPV infection, emphasizes the role of cytopathology as a powerful diagnostic tool for recognizing a unique and unexpected lesion.

Postpartum Uterine Prolapse and Vaginal Cystocoele in a Murrah Buffalo

A pluriparous Murrah buffalo was presented with vaginal tear over fornix vagina along with post-partum prolapse of uterus, cervix and urinary bladder. The case was managed by suturing of vaginal wall after repositioning the prolapsed mass. The catheterization of urinary bladder and modified Buhner's sutures through vulvar lips were applied to prevent the recurrence of the condition.

An Evaluation Study of Hospital Acquired Infections in Thi-Qar province, Iraq

The present study was evaluated for the six months (1st October 2014 to 30th March 2015), the proportion of acquired infection in the Al-Imam Hussain Teaching Hospital at Al-Nasiriya province south of Iraq has studied. The relationship also estimated between employments and their variables such as age, gender, residence, medical department, social status and different distribution infections among staff in the hospital. The result showed discrepancy rate of occurrence and recording the incidence of cases. Common causes of hospital-acquired infections include urinary bladder catheterization, respiratory procedures, surgery and wounds and intravenous procedures. The most common bacterial isolates were Staphylococcus spp., Pseudomonas spp., Escherichia coli and Klebseilla spp. respectively. In conclusion, the acquired infection rate is an indicator of quality and safety of care. The development of a surveillance process to monitor this rate is an essential step to identify local problems and priorities, and evaluate the effectiveness of infection control activity.

Use of Positron Emission Tomography for Pregnancy-Associated Cancer Assessment: A Review.

Background. Positron emission tomography (PET) has proven clinical utility both in the initial and relapse staging phase, but this technique is controversial during pregnancy. The objective of this review is to provide a compendium of available information on the use of PET during pregnancy. Materials and methods. A systematic literature review was conducted from 1 January 2004 until 20 May 2021. A total of 4 small series and 9 case reports consisting of 25 cases were selected. Results. During the first trimester, the fetus is most sensitive to ionization damage, so lower doses are recommended (2.6E-02 mGy/MBq). Fetal-effective doses are higher in this period and the average fetal dose (4.06 ± 3.22 mGy) remains significantly below the threshold for deterministic effects. During the second and third trimesters, recommended doses are higher (1.4E-02 mGy/MBq at 6 months, and 6.9E-03 mGy/MBq at 9 months of gestation). 18F-FDG activity was distributed to the whole fetus with a prevalence of myocardial tissue in seven cases. The use of special precautions, such as PET-magnetic resonance (MR) and urinary bladder catheterization, reduces the amount of radioactive tracer. Breastfeeding interruption is not recommended. Conclusions. 18F-FDG PET is not contraindicated in pregnancy, but multidisciplinary discussion is necessary and strict precautions are recommended.

Demonstrate, Observe, Assist, and Perform versus structured educational video in imparting standard skill in male urinary bladder catheterization

Background: Conventional teaching-learning methods often fail to assure competency in male bladder catheterization (MBC) in the Indian Medical Graduate. Introduction of structured training methods could offer a solution. Aims and Objectives: The objective of the study was to compare efficiency of demonstrate, observe, assist, and perform (DOAP) method of training in a skill lab against structured educational video (SEV)-based learning in training final MBBS students in the psychomotor skill to safely perform MBC. Materials and Methods: Following IRB and IEC clearance, final MBBS students fulfilling selection criteria were randomly allocated into two comparable groups. One group underwent skill lab training using DOAP method while the other group underwent training using a SEV by the same instructor. CRRI interns, regularly performing MBC at work by virtue of conventional training, with 6–8 months experience formed a control group. All participants underwent assessment of skill in MBC by skill lab OSCE evaluation, by assessors blinded to the participant’s method of training. Data were recorded and analyzed using standard statistical software. Trial evaluation from the trial groups was obtained using SurveyMonkey tool. Results: There was no statistically significant difference in the ability of DOAP group or SEV group to safely perform MBC though a higher level of confidence was expressed with their training by DOAP group. Both trial groups statistically outperformed the control group. Conclusion: Structured training assures competence. Video-assisted training produces comparable results though DOAP method is preferred by students. A combination of the techniques may facilitate optimal training.

Aspects of Prevention of Urinary Tract Infections Associated with Urinary Bladder Catheterisation and Their Implementation in Nursing Practice.

In the case of the prevention of catheter-associated urinary tract infections (CAUTI) related to healthcare provision, high-quality and comprehensively provided nursing care is essential. Implementation of preventive strategies is based on recommended procedures, and the introduction of whole sets of measures has been shown to be effective. The objective of this research is to find out whether the providers of acute bed care have implemented the steps of CAUTI prevention, and specifically which measures leading to improved quality of care in the area of urinary infections are already in place. To determine this, we carried out quantitative research. Data were collected using a questionnaire-based investigation; we used two non-standardised and one standardised questionnaire, and the respondents were general nurses in management positions (n = 186). The results revealed that result-related CAUTI indicators are monitored by only one-third of the respondents, and records of catheterisation indication are not kept by 17.3% of general nurses. The results of the research showed deficiencies in the monitoring of CAUTI outcome and process indicators, and a weakness of the implemented preventive measures is the maintenance of catheterisation documentation. Periodic CAUTI prevention training is not implemented as recommended. It is positive that there are well-working teams of HAI prevention experts in hospitals.

Ureteric Rupture: Rare Complication of Inappropriate Urinary Bladder Catheterization

AbstractWe have reported case of 71-year-old male with acute urinary retention due to gross prostatomegaly. Due to inappropriate catheterization, urinary bladder remained distended and ultimately caused left ureteric rupture. This article is peculiar as it shows that misplaced Foley's catheter may also lead to exceedingly rare complication of ureteric rupture and highlights importance of proper management of difficult catheterization which is otherwise considered a simple procedure.

Does a prior hysterectomy complicate transvaginal/transumbilical hybrid NOTES cholecystectomy?\u2014a comparative analysis of prospectively collected data

PurposeHysterectomy alters the anatomy of the posterior vaginal vault used as access for transvaginal/transumbilical hybrid NOTES cholecystectomy (NC), creating potential consequences for the feasibility and complication rate of the procedure. Therefore, the aim of our retrospective analysis of prospectively collected data was to analyze the postoperative course after NC in previously hysterectomized (PH) patients compared with patients who had not undergone hysterectomy (NH).MethodsA total of 126 NH patients and 50 PH patients aged over 42 who had an NC from 12/2008 to 04/2021 were compared regarding age, body mass index (BMI), ASA classification, number of percutaneous trocars, need for intraoperative urinary bladder catheterization, length of procedure, conversion rate, and intraoperative and postoperative complication rate according to the Clavien/Dindo classification, Comprehensive Complication Index (CCI), mortality, and hospital length of stay.ResultsPH patients were older than NH patients (63.0 vs 51.5 years; P < 0.001) but did not differ significantly in ASA classification (P = 0.595) and BMI (26.8 vs 27.9 kg/m2; P = 0.480). They required more percutaneous trocars (P = 0.047) and longer procedure time (66.0 vs. 58.5 min; P = 0.039). Out of all 287 scheduled NC only one had to be “converted” to traditional laparoscopic cholecystectomy. Intraoperative and postoperative complication rates, Clavien/Dindo classification, CCI, need for intraoperative urinary bladder catheterization, and length of stay did not differ significantly.ConclusionOur results indicate an increased degree of difficulty of NC in PH patients, although there is no major impact on intraoperative and postoperative complication rates. Urinary bladder perforation is a specific access-related complication in PH patients.

Frailty predicts failure to discharge patients home from a subacute-care unit: a 3-year Italian experience

BackgroundThe primary purpose of Subacute Care Units (SCU) is to decongest acute hospital wards and facilitate the return of older patients to home.AimsWe analyzed the clinical characteristics and outcomes of patients admitted to an Italian SCU, and we explored factors associated with discharge to locations other than home (outcome).MethodsThis retrospective observational cohort study was conducted at a medium-sized suburban hospital, enrolling all patients consecutively admitted to one SCU from October 2017 to February 2020. We collected demographics, cause of admission, comorbidities, cognition, Barthel Index (BI), nutritional status, Clinical Frailty Scale (CFS), length of stay, and discharge destination. Delirium was screened with the 4AT score. We adopted a multivariable conditional logistic regression model to identify the factors associated with the outcome.ResultsFrail subjects accounted for 58.6% of 406 patients (mean age 78.2 years, SD 11.6), while 61% were classified as functionally dependent. More than half of patients had relevant comorbidity, approximately 80% had a poor nutritional status, and 25% had pre-existing dementia. The overall prevalence of delirium was 14.5%. Most patients came from a hospital setting; recurrent reasons for admission were infections (70.5%) and heart failure (12.7%). Having a urinary bladder catheter at discharge, being overtly frail (CFS > 8), and low BI score were factors independently associated with not being discharged home.Discussion and conclusionThe routine assessment of frailty, as expressed by the CFS, may help redirecting the patients eligible for SCU admission.

Purple urine bag syndrome: When the urine turns purple – An under diagnosed spot diagnosis

The Purple Urine Bag Syndrome (PUBS) is a rare condition in which the urine turns purple. It may occur in Urinary Tract Infections (UTIs) when bacteria metabolize dietary tryptophan to indole resulting in indigo (blue) and indirubin (red). This condition is mostly seen in elderly female patients with permanent urinary bladder catheterization. Patients, relatives and health professionals may be concerned about this discolouration, which is usually harmless. Medical management of PUBS involves frequent urinary bag change, antibiotic therapy and most importantly reassurance. We report an 89-years-old long-term catheterized female nursing home resident who was admitted to the emergency room because of a Community Acquired Pneumonia (CAP). After a few days of inpatient treatment her urine bag turned purple. Antibiotic therapy continued and the indwelling urinary catheter was changed resulting in clear urine. Keywords: Purple urine bag syndrome (PUBS); purple discolouration; urinary tract infection (UTI); long-term catheterization.

Reduced Need for Urinary Bladder Catheterization in the Postanesthesia Care Unit After Implementation of an Evidence-based Protocol: A Prospective Cohort Comparison Study

BackgroundPostoperative urinary retention (POUR) is a known complication in the postanesthesia care unit (PACU). The variations in catheterization thresholds contribute to unnecessary invasive procedures. ObjectiveIn the current study, we implemented an algorithm for a sterile intermittent catheterization (SIC) threshold of 800 ml with volume-dependent bladder scan intervals and compared the incidence of SIC with that of a matched patient cohort threshold of 400 ml. Design, setting, and participantsThis comparative study of two prospective historical cohorts represented two thresholds for POUR, set at 400 ml without a standardized bladder scan protocol and 800 ml with a volume-dependent bladder scan protocol. Outcome measurements and statistical analysisThe primary outcome was the frequency of catheterization during the PACU stay. Secondary outcomes evaluated patient safety aspects in occurrence of thresholds above 400/800 ml. The study was set at the PACU under the Department of Anesthesia, Center for Cancer and Organ Diseases, Rigshospitalet, Denmark. Results and limitationsIn total, 741 patients were consecutively included, with 307 in the POUR-400 and 434 in the POUR-800 group, and with comparable group characteristics. Significantly fewer patients fulfilled the SIC/catheter a’ demeure (CAD) criteria in the POUR-800 (5.0%) versus POUR-400 (14.3%) group, equivalent to a 65.0% relative reduction in SIC. ConclusionsImplementation of a standardized ultrasound-guided protocol with volume-dependent scan intervals and an evidence-based catheterization threshold of 800 ml decreases the need for SIC by >65%, without increasing the need for urinary catheterization at the wards. Patient summaryIn this study, we implemented an algorithm for a sterile intermittent catheterization threshold of 800 ml with volume-dependent bladder scan intervals. A marked reduction was seen in catheterization in the postanesthesia care unit, without increasing catheterization rates at the ward.

Comparison of the level of sensory blockade achieved when spinal anaesthesia is performed for caesarean section before and after urinary bladder catheterisation: a randomised controlled study

Background: Spinal anaesthesia has a prominent place in obstetric anaesthesia. Factors affecting the sensory level and the depth of anaesthesia and associated complications have been topics for much discussion. One such topic is whether keeping the patient supine for bladder catheterisation after the spinal injection would enhance spread of the anaesthetic agents upwards in the subarachnoid space leading to grave complications. Objectives: To observe whether there was a clinically significant difference in the sensory levels achieved, changes in blood pressure and pulse rates when bladder catheterization was done before as opposed to after spinal anaesthesia, for caesarean section. . Method: 106 pregnant women undergoing cesarean section were randomised into two groups, with one group receiving spinal anaesthesia before bladder catheterisation and the other receiving spinal anaesthesia after catheterisation. Results: The initial sensory level of T4 was achieved by 76% and 53.4% women who were catheterized before and after spinal anaesthesia respectively. The systolic and diastolic blood pressure dropped, and the pulse rate increased in both groups. There was no significant difference in either the spinal sensory level achieved, or the blood pressure and pulse rate changes observed whether the bladder was catheterized before or after spinal anaesthesia. Conclusions: There was no difference in either the spinal sensory level achieved or the haemodynamic changes irrespective of whether the bladder was catheterized before or after spinal anaesthesia.

A novel insertion technique for urinary catheters in female dogs with the use of a guidewire.

BackgroundComplicated transurethral urinary bladder catheterization in female dogs is a commonly encountered urologic problem, often causing inadvertent trauma to the lower urinary tract and breach in aseptic technique.Key ConceptsA novel method for transurethral insertion of urinary catheters in female dogs is described. The main variation from current procedures involves the application of the Seldinger technique with the use of an introduction catheter that is specifically designed to feed into the urethra, and the use of a guidewire to replace the introducer with an indwelling balloon catheter.SignificanceThe technique presented offers a step‑by‑step approach that could improve success in urinary catheter placement. This modification may facilitate catheter insertion, be less traumatic, and offer better control of asepsis, especially with challenging urethral catheterization. The technique also offers an easy method to replace the catheter. Application of the technique may reduce catheter‐associated urinary tract infections as it addresses certain infection‐related risk factors. Prospective validation studies are needed to support its advantages over current urinary catheter placement techniques.

Outcomes after Early versus Delayed Urinary Bladder Catheter Removal after Proctectomy for Benign and Malignant Disease in 2,429 Patients: An Observational Cohort Study.

Background: There currently is no standard practice for optimal urinary catheter removal after rectal resection (proctectomy). Delayed removal may increase urinary tract infection risk, an important hospital quality metric. This study aimed to assess the effect of catheter duration on urinary tract infection rate. We hypothesized that early removal would be associated with fewer infections. Methods: We performed a retrospective review of patients who underwent proctectomy from January 2007 to December 2017 with urinary catheter placement in our colorectal surgery department. The main outcome measures were urinary tract infection, post-operative urinary retention, and length of stay. Patients were divided into early (post-operative day one or two) and late (day three or later) removal groups. Results: A series of 2,429 patients were included; 1,176 in the early and 1,253 in the late group. The early group had a shorter median length of stay (5.26 versus 7 days). The urinary tract infection (n = 77) multivariable logistic regression model showed no association between timing of removal and infection; however, females had more infections (odds ratio [OR] 2.70, 95% confidence interval [CI] 1.65-4.41). The post-operative urinary retention model (n = 280) showed no association between the timing of removal and retention; however, patients who underwent pre-operative radiation (OR 1.55; 95% CI 1.15-2.09) or total proctocolectomy (OR 1.74; 95% CI 1.21-2.49) or were male (OR 1.35; 95% CI 1.02-1.78) were more likely to have retention. When analyzed by specific removal day, each one-day delay in removal increased the odds of infection by 21% (OR 1.21; 95% CI 1.09-1.35] and decreased the odds of retention by 12% (OR 0.88; 95% CI 0.80-0.97] with a cross-over at 9 days. Patients who experienced retention were not more likely to have infection. Conclusion: Early urinary catheter removal after proctectomy was associated with a lower urinary tract infection rate and a shorter hospital stay.

Quality of life and the prevalence of urinary incontinence after surgical treatment for gynecologic cancer: a questionnaire survey

BackgroundAlthough there have been a number of reports on urinary voiding symptoms associated with surgical interventions for gynecologic cancer and post-voiding symptoms, there have been few reports on urinary storage symptoms such as urinary incontinence (UI) and overactive bladder (OAB). The purpose of this study was to examine the rates and impact on quality of life (QOL) of urinary storage symptoms after gynecologic cancer surgery.MethodsA questionnaire survey, including Japanese-language versions of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), Overactive Bladder Symptom Score (OABSS), and Incontinence Impact Questionnaire-7 (IIQ-7), was distributed to gynecologic cancer patients who underwent hysterectomy between 2008 and 2013.ResultsOf the 145 patients analyzed, 49 (33.8%) had UI pre-surgery, and 76 (52.4%) had UI post-surgery, including 34 (35.4%) first-time UI patients, with a significant difference between pre- and post-surgery. Of the 49 subjects with UI pre-surgery, 43 (87.7%) had stress incontinence, while of the 76 patients with UI post-surgery, 44 (57.1%) had stress incontinence, and 24 (31.2%) had mixed incontinence. Seven (4.8%) subjects had OAB pre-surgery, whereas 19 (13.1%) had OAB symptoms post-surgery (including 15 first-time OAB patients), with a significant difference between pre- and post-surgery. IIQ-7 scores were markedly higher for patients with mixed incontinence post-surgery than for those with stress incontinence, indicating a lower QOL. Logistic regression analysis identified the number of Cesarean sections and days of urinary bladder catheterization as risk factors for postoperative UI.ConclusionsUI and OAB rates were higher after gynecologic cancer surgery than in the general female population. The mixed incontinence rate was markedly higher post-surgery; QOL was low for such patients due to the combination of urge and stress incontinence. Multiple Cesarean sections and urinary bladder catheterization post-surgery were risk factors for post-surgical UI.

The Effect of Bladder Catheterization Technique on Postoperative Urinary Tract Infections After Primary Total Hip Arthroplasty

BackgroundUrinary bladder catheters are potential sources of infection after total hip arthroplasty (THA). Therefore, the goal of this study was to determine if intermittent catheterization provides a decreased risk of postoperative urinary tract infections (UTIs) compared with indwelling catheterization in THA patients. MethodsPatients undergoing THA at 15 hospitals within a large health system were prospectively collected between 2017 and 2019 and then stratified based on catheterization technique: no-catheter; indwelling catheter–only; intermittent catheter–only; and both intermittent and indwelling catheter. Patient demographics, medical comorbidities, anesthesia types, and postoperative UTIs were assessed. Independent Student t-tests were used to perform univariate analyses for the catheterization groups. Multiple linear regression models were used to compare the different groups while controlling for confounding variables. ResultsThere were a total of 7306 THA patients recorded with 5513 (75%) no-catheter, 1181 (16%) indwelling catheter–only, 285 (3.9%) intermittent catheter–only, and 327 (4.5%) indwelling and intermittent catheterization patients. A total of 580 patients experienced postoperative UTI. Urinary bladder catheterization increased the risk of postoperative UTIs (P < .001) in univariate analyses. Multiple linear regression models showed that indwelling catheter-only (OR: 2.178, P < .001), intermittent catheterization (OR: 1.975, P = .003), and both indwelling and intermittent (OR: 2.372, P = .002) were more likely to experience UTIs compared with no catheters. ConclusionThis study found that patients treated with indwelling catheterization, with or without preceding intermittent catheterization, were significantly more likely to experience UTIs. Therefore, in an effort to decrease the risk of UTIs, THA patients experiencing postoperative urinary retention should be treated with intermittent catheterization.
