ABSTRACT
PURPOSE: It has been proposed that reusable catheters are more cost effective and environmentally sustainable than single-use catheters intended for intermittent catheterization (IC). However, the aspect of individuals' well-being and preference for catheter type is not considered. In this study, we investigated the impact on individuals' health-related quality of life (HR-QoL) when testing a reusable catheter. MATERIALS AND METHODS: The study was an open-labeled, single-arm, multicenter investigation with a treatment period of 28 days. Forty subjects using single-use hydrophilic catheters were accustomed to a reusable catheter for managing IC. HR-QoL was evaluated by the Intermittent-Self Catheterization Questionnaire (ISC-Q). Additionally, satisfaction was evaluated by the Intermittent Catheterization Satisfaction Questionnaire (InCaSa-Q). The difference in total score was analyzed using a mixed linear model. Furthermore, preference for IC (single-use vs. reusable) was assessed and microbial evaluation of the catheters was performed. RESULTS: The total ISC-Q score measuring HR-QoL decreased significantly by 28% (p < 0.001). Two of the four subdomains (ease-of-use and discreetness) also decreased significantly (p < 0.001). The total InCaSa-score and all four subdomains evaluating satisfaction decreased significantly (p < 0.005). The primary study results were supported by the fact that 90.9% of subjects preferred to use a single-use catheter for IC. Furthermore, 50% of reusable catheters were contaminated with bacteria. CONCLUSION: Switching from single-use to reusable IC resulted in a significant decrease in HR-QoL and satisfaction. Moreover, the vast majority preferred the single-use catheter due to handling and convenience. The users' rights to their preferred bladder management method should be acknowledged.
ABSTRACT
Background: Bladder dysfunction is a common complication following radical hysterectomy, affecting patients' QOL. Exploring interventions, particularly IC continuity care, is crucial for identifying strategies to enhance postoperative outcomes. This study aimed to assess the impact of continuous intermittent catheterization (IC) care on bladder function recovery and quality of life (QOL) in patients undergoing radical hysterectomy for cervical cancer. Methods: The primary outcome measured was the time to bladder function recovery, with secondary outcomes comprising EORTC QLQ-C30 assessments at 3 and 6 months post-surgery, as well as EORTC QLQ-CX24 evaluations. Meanwhile, urinary complications, readmissions, and outpatient follow-up were also compared. Results: Among the 128 participants, with 64 in each group, indwelling catheterization durations were similar. However, the IC continuity care group exhibited significantly shorter IC duration and bladder recovery time. This group demonstrated superior QOL, lower occurrence rates post-IC, reduced urethral injuries, and higher readmission and outpatient follow-up rates. Conclusion: This study underscores continuous IC care emerges as a beneficial intervention, facilitating accelerated bladder function recovery and improved QOL in patients following radical hysterectomy for cervical cancer.
ABSTRACT
INTRODUCTION: Iatrogenic injury during urethral catheterization is a common reason for inpatient urologic consultation and is associated with increased morbidity and resource utilization. Literature defining the patient population, interventions, or outcomes associated with traumatic catheterization is scarce. METHODS: We performed a retrospective review of consults for adult urethral catheterization at a single tertiary care center (July 2017-December 2019), with focus on patient characteristics and complications. Traumatic urethral catheterization was defined as catheterization by the primary team with at least 1 of these conditions: gross hematuria, meatal blood, or cystoscopic evidence of urethral trauma. Characteristics collected included urologic history, catheterization circumstances, procedural intervention, and subsequent visits. RESULTS: Three hundred urology consults for urethral catheterization were identified, including 98 (33%) traumatic events (5.3 incidents/1000 catheters placed). All traumatic catheterization consults were in men (median age 69 years). Most (71%) patients sustaining injury had significant urologic history (eg, benign prostatic hyperplasia, urethral stricture). Sixty-three (64%) consults were determined to be uncomplicated (not requiring any procedural intervention for catheter placement). Gross hematuria was the most common sequela (50% of patients). The 30-day catheter-associated urinary tract infection rate was 13%, and 2 patients developed sepsis. Complications required a total of 52 additional hospital admission days, 19 of which were intensive-care level, as well 113 outpatient urology visits. CONCLUSIONS: Traumatic urethral catheterization is associated with increased need for procedural intervention, risk of catheter-associated urinary tract infection, and additional resource utilization. Further studies on traumatic catheterization are needed to guide systemic efforts for minimizing injury and cost.

AIM: To determine the surgical indication and results of bladder augmentation (BA) during the last decade in a neurourology center in the era of intradetrusor botulinum toxin injection. MATERIAL: We conducted a retrospective study that included patients with BA between January 1, 2012 and December 31, 2022 in our centre. We collected pre-operative demographic, clinical, and urodynamic data, BA indication, and associated procedures. We analyzed early and late complications as well as continence and postoperative voiding mode in patients with first BA in a neurological pathology context. RESULTS: We performed 77 BA over the study period. The main indication was neurogenic overactive bladder, which was secondarily resistant to botulinum toxin. The main associated procedure was continent cutaneous diversion (n=31, 57.4%). Among patients who had a first BA for neurogenic bladder, 34 patients had early complications (50%) including 12 patients with≥Clavien 3 complications (17.6%). After a median follow-up of 33 [14; 55] months, 23 patients had late complications (33.8%) and 59 patients had complete continence (86.8%). CONCLUSION: In the era of botulinum toxin, the main indication of BA is the secondary failure of botulinum toxin for overactive neurogenic bladder. The BA provided continence in 86.8% of patients. It remains however an intervention with a significant rate of severe complications whose indication must be discussed by a multidisciplinary team. LEVEL OF EVIDENCE: Weak.

BACKGROUND: Little is known about the effect of catheterization during pressure-flow studies (PFS) on voiding efficiency in children. Our objective was to determine the effect of urethral catheterization on Qmax and flow index (FI) during PFS compared to the free flow of uroflowmetry (UF). METHODS: We retrospectively reviewed 63 consecutive children who underwent UF and PFS at our center on the same day (2019-2022). Voiding data was available for 46 patients. Patients first underwent a UF with full bladder, then PFS after urethral catheter insertion. Patients with urethral pathologies (n = 6), on clean intermittent catheterization (CIC) (n = 2) and with major comorbidities (n = 2) were excluded. Indications for UF/PFS were LUTS, recurrent UTIs, incontinence or neurosurgical pre-operative evaluation. Data was collected from the UF and the PFS and compared using paired t-test. The idealized Qmax and flow index (FI) were calculated for UF and PFS using the formulas described by Franco et al.: Male Qmax = 11.26 + 0.0701(TBC [total bladder capacity]) - 0.0000513(TBC); Female Qmax = 10.723 + 0.073(TBC) - 0.0000423(TBC), FI = Actual Qmax/Expected Qmax (Franco and et al., 2016; Franco et al., 2018; Franco and et al., 2016). RESULTS: Median age was 7 years old (IQR 5-11). Twenty-one (40%) patients were male and 32 (60%) patients were female. Of the 53 patients, 3 boys and 4 girls (n = 7; 13%) were unable to void with the catheter in place during PFS but able to void after its removal. Of the remaining 46 cases, the Qmax during PFS was 5 mL/s slower than the Qmax recorded on the UF without catheter, representing a decrease of 29% (12.3 vs 17.3 mL/s; p < 0.0001). The impact of urethral catheter during PFS was more important in males vs females (Qmax decreased by 7.7 vs 3.3 mL/s, or 45 vs 19%). The mean FI during PFS was 44%, which was a 30% reduction compared to the 74% FI obtained with UF (p < 0.00001). In males, the FI decreased by 37% on PFS, whereas it decreased 26% in females, similar to the Qmax decrease. CONCLUSIONS: Voiding efficiency, as assessed by Qmax and FI, is decreased during PFS compared to uroflow studies. Our data documents for the first time the impact of urethral catheterization on pediatric voiding efficiency. Abnormal flow rates and elevated PVRs should be used to guide patient management only if obtained by uroflow. Prospective validation comparing free flow with PFS studies will help characterize the impact of urethral catheter relative to bladder pathology, age, gender and catheter size used.

Despite the risk of developing catheter-associated urinary tract infections (CAUTI), catheter reuse is common among people with spinal cord injury (SCI). This study examined the microbiological burden and catheter surface changes associated with short-term reuse. Ten individuals with chronic SCI reused their catheters over 3 days. Urine and catheter swab cultures were collected daily for analysis. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analyses were used to assess catheter surface changes. Catheter swab cultures showed no growth after 48 h (47.8%), skin flora (28.9%), mixed flora (17.8%), or bacterial growth (5.5%). Asymptomatic bacteriuria was found for most participants at baseline (n = 9) and all at follow-up (n = 10). Urine samples contained Escherichia coli (58%), Klebsiella pneumoniae (30%), Enterococcus faecalis (26%), Acinetobacter calcoaceticus-baumannii (10%), Pseudomonas aeruginosa (6%) or Proteus vulgaris (2%). Most urine cultures showed resistance to one or more antibiotics (62%). SEM images demonstrated structural damage, biofilm and/or bacteria on all reused catheter surfaces. XPS analyses also confirmed the deposition of bacterial biofilm on reused catheters. Catheter surface changes and the presence of antibiotic-resistant bacteria were evident following short-term reuse, which may increase susceptibility to CAUTI in individuals with SCI despite asymptomatic bacteriuria.
ABSTRACT
INTRODUCTION: Acute urinary retention (AUR) is one of the most severe symptoms of Benign Prostatic Hyperplasia (BPH). There are some studies in the literature describing the risk factors for the development of AUR in BPH patients. However, the studies that summarize the effect of AUR on Transurethral resection of Prostate (TUR-P) surgery results are limited. The aim of this study is to assess the effect of AUR on TUR-P results. METHODS: Between 2018 and 2020, patients who underwent TUR-P for AUR or lower urinary tract symptoms (LUTS) were included in the study. The inclusion criteria were, men over 50 years old with a BPH diagnosis and who underwent monopolar TUR-P by a single surgeon. The exclusion criteria were; patients who had prostate cancer, multiple sclerosis, or neurogenic bladder were diagnosed or had previous lower urinary tract surgeries such as TUR-P, TUR-Bladder, Urethrotomy, had a chronic indwelling catheter, and patients who did not accept immediate TUR-P and preferred trial without catheter (TWOC) protocol. The age, PSA, prostate volume, pre- and post-operative flow rates, duration of hospitalization, and complications were recorded. Two groups were constituted for comparison such as AUR and Elective Group and p values <0.05 were considered significant. RESULTS: There were 14 and 46 patients for AUR and Elective Groups respectively. The age, pre-operative prostate volume, free and total PSA values, postoperative complication rate, and re-hospitalization rate were significantly higher in the AUR-Group. However, there were no differences between groups in terms of pre-operative medication, duration of hospitalization, and post-operative uroflow maximum flow rate. DISCUSSION: Patients who underwent TUR-P after AUR have a higher risk for complications and re-hospitalization. Care should be taken in these patients and patients should be warned about the risks.

BACKGROUND: To investigate the clinical effect of better nursing education on patients' postoperative urination after renal biopsy. METHODS: In this study, patients who underwent renal biopsy in the Department of Nephrology at our hospital were selected as the observation group (July-December 2018, n = 120) and control group (January-June 2018, n = 110) and received refined nursing education and routine nursing education, respectively. Postoperatively, the causes of dysuria after puncture, the degree of postoperative pain, and the urination mode were compared between the two groups. RESULTS: Six patients in the observation group and 23 patients in the control group needed urethral catheterization, accounting for about 5% and 15.2%, respectively. Therefore, the postoperative catheterization rate in the observation group was significantly lower than the control group, with a statistically significant difference. CONCLUSION: The refined nursing education proposed in this study can effectively improve urinary dysfunction after renal biopsy and has a clinical promotional value.

Prostatic inflammation and prostatic fibrosis are associated with lower urinary tract dysfunction in men. Prostatic inflammation arising from a transurethral uropathogenic E. coli infection is sufficient to increase prostatic collagen content in male mice. It is not known whether and how the sequence, duration and chronology of prostatic infection influence urinary function, prostatic inflammation and collagen content. We placed a transurethral catheter into adult male C57BL/6J mice to deliver uropathogenic E. coli UTI189 two-weeks prior to study endpoint (to evaluate the short-term impact of infection), 10-weeks prior to study endpoint (to evaluate the long-term impact of infection), or two-, six-, and ten-weeks prior to endpoint (to evaluate the impact of repeated intermittent infection). Mice were catheterized the same number of times across all experimental groups and instilled with sterile saline when not instilled with E. coli to control for the variable of catheterization. We measured bacterial load in free catch urine, body weight and weight of bladder and dorsal prostate; prostatic density of leukocytes, collagen and procollagen 1A1 producing cells, and urinary function. Transurethral E. coli instillation caused more severe and persistent bacteriuria in mice with a history of one or more transurethral instillations of sterile saline or E. coli. Repeated intermittent infections resulted in a greater relative bladder wet weight than single infections. However, voiding function, as measured by the void spot assay, and the density of collagen and ProCOL1A1+ cells in dorsal prostate tissue sections did not significantly differ among infection groups. The density of CD45+ leukocytes was greater in the dorsal prostate of mice infected two weeks prior to study endpoint but not in other infection groups compared to uninfected controls.
ABSTRACT
OBJECTIVES: The aim of this study was to evaluate the use of inhalant anesthesia vs sedation for urinary catheter placement in male cats with urethral obstruction. The primary outcome measures were the incidence of complications related to catheterization, the incidence of recurrent urethral obstruction (rUO; both during hospitalization and within 1 year) and survival. The secondary aim of this study was to evaluate the association between baseline serum biochemical concentrations and antispasmodic medications with complications and short-term rUO. METHODS: We carried out a retrospective review of records from a university teaching hospital from 2009 to 2020. Cats were included if diagnosed with a urinary obstruction, based on the presence of a large, painful and non-expressible bladder, a urinary catheter was placed and hospitalization occurred for a minimum of 24 h. Collected baseline data included age, breed, weight, serum biochemical concentrations and if cats underwent sedation or inhalant anesthesia for urethral catheterization. For the comparison of inhalant anesthesia or sedation, univariate logistic regression was used. RESULTS: There was no statistically significant difference in complications or the recurrence of obstruction in cats with urethral obstruction that underwent inhalant anesthesia compared with sedation. All serum biochemical concentrations were significantly associated with survival. Decreased serum ionized calcium was found to be statistically significantly associated with higher complication rates (P = 0.0086), as well as short-term recurrence of obstruction (P = 0.004). Increased serum potassium concentrations were found to be statistically significantly associated with the risk of short-term recurrent urethral obstruction (P = 0.0345). No significant difference was found between the use of antispasmodic medications with short-term recurrence. CONCLUSIONS AND RELEVANCE: No significant difference was found between complications or recurrence rates when comparing the use of inhalant anesthesia to sedation protocols. Baseline serum biochemical data were significantly associated with complications, survival and short-term recurrence rates.

AIMS: This study was conducted to identify potential risk factors for permanent clean intermittent catheterization (CIC) and incontinence in patients with lipomyelomeningocele (LMMC) and evaluate how LMMC affects bladder function prognosis, measured by urodynamic (UD) score. METHODS: This retrospective study analyzed the electronic health records of patients who underwent primary neurosurgical repair for LMMC at a single tertiary referral center between January 2012 and December 2016 and were followed at least 3 years after surgery. Data regarding bladder function were obtained from medical records for multiple time points, including before surgery, after surgery but before hospital discharge, 3 months after surgery, and at outpatient visits during follow-up. RESULTS: This study enrolled 120 patients. At a mean follow-up of 62.6 ± 13.9 months after primary neurosurgical LMMC repair, 22 (18.3%) patients continued to require CIC for bladder emptying, only 7 (31.8%) of whom maintained bladder continence. A multivariate logistic regression model identified age at the time of surgery and the type of LMMC as significant presurgical prognostic risk factors for permanent CIC. In addition, postoperative urinary retention and a UD score greater than or equal to 5 measured 3 months after surgery were identified as significant postsurgical risk factors for permanent CIC and urinary incontinence. A linear mixed model adjusted for age at the time of surgery showed that patients with a transitional or chaotic LMMC type were more likely to experience gradual bladder function decline than patients with other LMMC types. CONCLUSIONS: This study identified both presurgical (age at the time of surgery, LMMC type) and postsurgical (postoperative urinary retention, UD score greater than or equal to 5 at 3 months postsurgery) risk factors for permanent CIC and urinary incontinence. In addition, LMMC type was identified as a prognostic risk factor for bladder function decline. These results will enhance the current understanding of bladder function outcomes in patients who undergo surgical treatment for LMMC.

ABSTRACT
OBJECTIVES: The purpose of this study was to evaluate the correlation between clinical aspects and urethral lesions with reproductive status and age at neutering in obstructed male cats. METHODS: All cats with compatible signs of urethral obstruction (UO) treated at the Veterinary Hospital of the Federal Rural University of Pernambuco from 2019 to 2021 were divided into three groups according to their reproductive status: intact; prepubertal neutered; and post-pubertal neutered. Cats with compatible signs of UO were selected for further analysis. Age, clinical signs, age at neutering and age of the first obstructive event were documented. Cats with recurrent obstructive urinary signs or urethral trauma that made catheterization impossible were referred for perineal urethrostomy. The morphology of the excised penises was assessed by histopathological analysis. RESULTS: Of 84 cats with signs of UO included in this study, 28.6% were classified as intact, 28.6% as prepubertal neutered and 42.8% as post-pubertal neutered. Intact cats had a significantly earlier onset of UO compared with prepubertal and post-pubertal neutered cats, as seen by the age at obstruction (3.6 vs 5.7 and 5.5 years, respectively). Similar clinical signs and histopathological lesions were observed in all groups. The main clinical signs observed were stranguria, hematuria and pollakiuria. All cats had some degree of injury in the penile urethra. The most common lesions were hemorrhage, fibrosis and congestion. CONCLUSIONS AND RELEVANCE: It appears that intact cats had an earlier onset of UO than neutered cats, regardless of age at neutering. Urethral histopathological lesions and clinical signs were similar in both groups. Pediatric neutering represents a useful tool in the control of abandoned and stray animals and the consequent dissemination of zoonoses, thus having a positive impact on public health.

Urethral catheterization (UC) is a common procedure done in the Emergency Department of a hospital. The main indications for a UC are relieving acute urinary retention and bladder outlet obstruction. This cross-sectional audit was carried out between July 2019 to February 2020, in the Emergency Department (ED). All male patients aged 18 years and above, in whom UC was performed, were included in the audit. A total of 81 male patients were surveyed. Although, sterilized technique was maintained by using sterile gloves and pyodine but hand hygiene (sterilization or hand wash) was not performed before the procedure 80% of times. CDC hand hygiene guidelines were distributed to promote hand hygiene. What do we already know about this topic ? The Lippincott guidelines are considered gold standard which includes hand hygiene as an important element of urinary catheterization UC. The CDC Center of Disease Control CDC promotes the use of mandatory gloves and generous hand sanitizing before procedures. How does your research contribute to the field For continuous improvement and patient focused practice, we must audit the technique of nursing staff, doctors and health care assistants who are involved in insertion and ordering of catheters to provide quality health care and avoid unnecessary catheterization [1]. The aim of this study was to audit the appropriateness of usage of urinary catheters by the healthcare staff and, their technique of insertion and indications for urinary catheterization. What are your research's implications towards theory, practice, or policy? Hand hygiene is an important element of patient care. If done properly it can prevent several hospital-acquired infections. Heathcare facilities must audit their staff on regular basis and provide refreshers and promote the use of proper hand hygiene before urinary catheterization.
ABSTRACT
BACKGROUND: Distal renal tubular acidosis (dRTA) is the most common type of renal tubular acidosis (RTA) in children. Pediatric dRTA is usually genetic and rarely occurs due to acquired issues such as obstructive uropathies, recurrent urinary tract infections (UTIs), and chronic kidney disease (CKD). Although persistent hypokalemia frequently occurs with dRTA, acute hypokalemic paralysis is not frequently reported, especially in older children. CASE PRESENTATION: An eight-year-old girl presented with an acute first episode of paralysis. A physical examination revealed normal vital signs, short stature consistent with her genetic potential, and decreased muscle strength of her upper and lower extremities. Preexisting conditions included stage 4 CKD due to recurrent UTIs, severe vesicoureteral reflux and bilateral hydronephrosis, neurogenic bladder, and multisegment thoracic syringomyelia. Her laboratory work-up revealed hypokalemic, hyperchloremic metabolic acidosis with a normal anion gap. She also had a urine osmolal gap of 1.9 mOsmol/kg with a high urine pH. Intravenous potassium replacement resulted in a complete resolution of her paralysis. She was diagnosed with dRTA and discharged with oral bicarbonate and slow-release potassium supplementation. CONCLUSIONS: This case report highlights the importance of considering dRTA in the differential diagnosis of hypokalemic acute paralysis in children. Additionally, in children with neurogenic lower urinary tract dysfunction and recurrent UTIs, early diagnosis of spinal cord etiology is crucial to treat promptly, slow the progression of CKD, and prevent long-term complications such as RTA.

PURPOSE: In April 2008, Medicare amended its policy for clean intermittent catheterization, increasing coverage from 4 reused catheters per month to up to 200 single-use catheters. The primary reason for the policy change was an assumed decrease in risk of urinary tract infection with single-use catheters. Given its economic/environmental impact (â¼50-fold increase in cost and plastic waste) and a paucity of supporting evidence, we retrospectively evaluate the policy's effect in a prospective spinal cord injury registry. MATERIALS AND METHODS: We accessed data for the years 1995 to 2020 from the National Spinal Cord Injury Database focusing on 1-year follow-up in those unable to volitionally void after injury. We asked 2 questions: (1) Did hospitalizations for genitourinary reasons decrease after the clean intermittent catheterization policy change?; and (2) Did clean intermittent catheterization adoption and adherence increase after the clean intermittent catheterization policy change? RESULTS: During the study period, 2,657 of the 6,843 (38.8%) participants unable to volitionally void after spinal cord injury were hospitalized during their first follow-up year. Of the cohort performing clean intermittent catheterization, fewer individuals were hospitalized for genitourinary reasons prior to the clean intermittent catheterization policy change compared to after (10.6% vs 14.6%, P < .001), a finding that persisted on multivariate logistic regression (odds radio, 0.67, P < .001). In addition, the number of individuals performing clean intermittent catheterization at 1-year follow-up was less after the policy change compared to prior (57.0% vs 59.1%, P = .044). CONCLUSIONS: Our findings suggest the 2008 policy change shifting clean intermittent catheterization coverage from catheter reuse to single-use did not decrease hospitalizations for urinary tract infection or increase clean intermittent catheterization uptake in individuals with spinal cord injury.

AIM: To summarize available data focused on diagnosis and management of urethral stricture in men with neurogenic lower urinary tract dysfunction by a systematic review of the literature. MATERIALS AND METHODS: A systematic review of the literature was carried out through an extensive electronic database search performed in PubMed/MEDLINE and Scopus databases for full texts, and International Continence Society, American Urology Association, and European Association of Urology abstracts for citations related to urethral structure. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. RESULTS: A total of 316 articles were identified, 48 of which were selected for this review. Different strategies are currently being used for the management of urethral strictures, such as clean intermittent catheterization (CIC) which reduces stricture by up to 68%; direct vision internal urethrotomy which shows lower rates of renarrowing; urethroplasty which shows a success rate up to 70%; urinary diversion is the treatment of choice when reconstruction is not possible. CONCLUSIONS: Further studies are needed in this population because of the heterogeneity of the outcomes and the lack of a standardized definition and classification of this population.

OBJECTIVE: The objective of this work was to anatomically locate the urethral orifice in female minipigs and describe the use of video laryngoscopes in urethral catheterization. METHODS: Urethral catheterization guided by a video laryngoscope was attempted in 16 adult female Bama minipigs. The anatomical location of urethral orifices, operating time and complications (mucosal edema and bleeding in the vaginal vestibule, and the numbers of red blood cells (RBCs) and white blood cells (WBCs) in mid-stream urine samples) were recorded. RESULTS: The anatomical location of the urethral orifice: the depth of the urethral orifice in female Bama minipigs was 4.2 ± 1.2 cm; all the urethral orifices were covered by mucosal folds of the vaginal vestibule. In the supine position, the orifice of the urethra at 9-12 and 1-3 o'clock accounted for 6.25%, 6.25%, 18.75%, 50%, 12.5%, 6.25% and 6.25%, respectively. All animals were successfully catheterized and the operating time was 9.0 (6.0-12.8) min. Complications: no bleeding in the vaginal vestibule was observed; the incidence of mucosal edema was 12.5%, all of which were mild; of urine samples collected 1 h after catheterization, 12.5% were found to contain RBCs and no RBCs were detected 6 h after catheterization; no WBCs were detected 1 h or 6 h after catheterization. CONCLUSIONS: The urethral orifice of female minipigs was located deep in the vagina at variable clock directions and was unexceptionally covered by mucosal folds. Applying a video laryngoscope in urethral catheterization allowed quick and accurate exposure of the urethral orifice and minimal operational injury in female minipigs.

Objetivos:Comparar e avaliar os atributos de dois cateteres vesicais para pessoa em tratamento com resíduo pós-miccional, no cateterismo intermitente limpo (CIL). Método: Estudo quantitativo, observacional e descritivo desenvolvido em ambulatório de referência para 48 municípios, entre setembro e novembro de 2020. Participaram 50 pacientes com resíduo pós-miccional que realizam CIL, com 44,8 anos de idade média, sendo 72% homens. Foram comparados dois cateteres lubrificados, de diferentes tecnologias, ambos com bolsa acoplada, por sete dias, na frequência de seis cateterismos diários, utilizando instrumento validado de percepção da satisfação do cliente. Os dados foram analisados por meio do software Statistical Package for the Social Sciences (SPSS) Statistics 23.0, e para comparação dos cateteres foi usado o teste não paramétrico de Wilcoxon. Resultados: O cateter de policloreto de vinila (PVC) pré-lubrificado com glicerol alcançou maior satisfação entre os participantes nos atributos avaliados (90% versus 86%) em relação ao cateter hidrofílico de poliuretano (PVP) pré-lubrificado, embora sem significância estatística nos escores parciais e totais do instrumento utilizado. Conclusão: O estudo possibilitou comparar os dois cateteres, e a avaliação do escore geral para ambos foi positiva. Algumas avaliações negativas para determinados atributos são passíveis de melhorias, além de ser esse modelo de estudo capaz de discriminar os cateteres, podendo ser reproduzido.
Objectives:To compare and evaluate the aspects of the use of two bladder catheters for the person undergoing treatment with post-void residual, in clean intermittent bladder catheterization (CIL). Method: Quantitative, observational, and descriptive analysis developed in a reference outpatient clinic, for 48 municipalities, from September to November 2020. Fifty patients with post-void residual, who underwent CVIL, took part in the study. Their average age was 44,8 years old, and 72% of them were male. Two lubricated catheters were compared, from different technologies, both with attached bags, for seven days, six catheterizations a day, using a validated instrument of perception of customer satisfaction. Data were analyzed by the software Statistical Package for the Social Sciences (SPSS) Statistics 23.0, and for the comparison of the two catheters it was used the Wilcoxon's non-parametric test. Results: The polyvinyl chloride (PVC) catheter pre-lubricated with glycerol reached greater participant satisfaction in the evaluated attributes (90 versus 86%) in relation to the hydrophilic polyurethane (PVP) pre-lubricated catheter, although there was no statistical significance on the partial or total scores of the instrument used. Conclusion: The study allowed the comparison of two catheters, and the evaluation of the general score for both was positive. Some negative evaluation for certain attributes is possible to be improved. This kind of study is able to discriminate the catheters, and it can be reproduced.
Objetivo:Comparar y evolución los atributos de las sondas vesicales para personas cometidas a tratamiento de residuo posmiccional, en cateterismo intermitente limpio (CIC). Método: estudio cuantitativo, observacional, descriptivo, realizado en un ambulatorio de referencia, para 48 municipios entre septiembre y noviembre de 2020. Participaron 50 pacientes con residuo posmiccional sometidos a CIC, edad media de 44,8 años, de los cuales el 72% eran hombres. Se compararon dos catéteres lubricados de diferentes tecnologías, ambos con bolsa adherida, durante 7 días, con una frecuencia de 6 cateterismos diarios, utilizando un instrumento validado para la percepción de satisfacción del cliente. Los datos se analizaron con el software SPSS Statistics 23.0 y se utilizó la prueba no paramétrica de Wilcoxon para comparar los catéteres. Resultados: El catéter de PVC - Cloruro de Polivinilo prelubricado con glicerol mostró mayor satisfacción de los participantes en los atributos evaluados (90% versus 86%) en relación con el catéter de PVP - catéter de poliuretano hidrofílico prelubricado, aunque sin significación estadística en el puntajes parciales y totales del instrumento utilizado. Conclusión: El estudio permitió comparar los dos catéteres y la evaluación de la puntuación general de los catéteres fue positiva. Algunas valoraciones negativas para determinados atributos son susceptibles de mejora y pueden ser implementadas, además de ser este modelo de estudio capaz de discriminar entre catéteres, y pudiendo ser reproducido.

Assisted reproductive technologies can aid conservation efforts via support of ex situ population management and preservation of genetic material. Data from 38 sperm collection attempts from 17 polar bears (1-5 procedures/bear) were evaluated. Sample collections were attempted via electroejaculation (EEJ; n = 6), urethral catheterization (UC; n = 25), or sperm rescue (SR; n = 7) during the breeding season (Jan. 1-May 21; n = 27) and nonbreeding season (May 22-Dec. 31; n = 11). Sperm retrieval was successful in 1 EEJ (16.7%), 18 UC (72.0%) and 4 SR (57.1%) collections. Initial sperm motility and viability were 50.0% and 77.0% for EEJ, 64.3 ± 7.4% and 80.9 ± 3.8% for UC, and 56.7 ± 8.8% and 80.5 ± 0.5% for SR. UC and SR were more likely to be successful during the breeding season (84.2-100%) than the nonbreeding season (25.0-33.3%). Testicular tumors were observed in four males (57%) during SR. In total, 13 samples were cryopreserved (n = 1 EEJ, 9 UC, and 3 SR) with egg-yolk-based equine extender (EQ) or OptiXcell (OP). For both extenders, post-thaw motility and viability were reduced by 20-60% and 30-65%, respectively. Further efforts to optimize procedures are warranted, but this summary provides data useful for enhancing the success of polar bear sperm collection and cryopreservation.
