Emphysematous cystitis: two cases report / 中华泌尿外科杂志

The 2 patients were both aged females with medical history of diabetes mellitus. The chief complaints were both hyperpyrexia. Laboratory tests presented markedly elevated white blood cells and C-reactive protein, indicating severe systemic infections. Urine culture confirmed the growth of Escherichia coli. CT scan revealed thickened bladder wall with intraluminal and interstitial collections of gas. After the diagnosis of emphysema cystitis was established, conservative treatments including bladder drainage, strict glycemic control and sensitive antibiotics were administered timely. Both of the 2 patients got fully recovery after standard treatment.

Reflections and perspectives on sacral neuromodulation in the treatment of refractory overactive bladder disorder / 国际外科学杂志

Overactive bladder (OAB) is a common urological condition. First-line treatment for OAB includes behavioral therapy as well as pharmacological treatment with M-blockers and β3-adrenoceptor agonists. Patients with OAB who fail behavioral therapy and do not achieve the desired outcome after 6-12 weeks of treatment with M receptor antagonists alone or who cannot tolerate the adverse effects of oral medications are referred to as refractory OAB. patients with refractory OAB can be treated with surgical interventions such as Sacral Neuromodulation (SNM), intravesical Botulinum Toxin type A. BTX-A and Percutaneous Tibial Nerve Stimulation. Compared with other procedures, SNM is highly effective and has a low incidence of adverse effects. The author contemplates that future studies of SNM for refractory OAB could be conducted to address the overall changes in intestinal flora-urinary flora-metabolomics and urinary control-related brain structure-spinal cord functional structure-peripheral pelvic floor nerve structure.

Cistite enfisematosa: um diagnóstico diferencial das infecções de trato urinário / Emphysematous cystitis: a differential diagnosis of urinary tract infection

Cistite enfisematosa (CE) é uma rara complicação de infecções do trato urinário, desenvolvida pela presença na bexiga de bactérias produtoras de gás, como Escherichia coli e Klebsiella pneumoniae. Ocorre mais comumente em mulheres acima de 60 anos e apresenta como principal fator de risco diabetes mellitus descompensado. O diagnóstico só é possível através de exames de imagem, uma vez que os sintomas são muito semelhantes a formas não complicadas de infecção urinária. Instituir precocemente o tratamento antimicrobiano é importante para reduzir as graves complicações que podem vir associadas a essa patologia. Descreve-se um caso clínico típico de paciente feminina, diabética descompensada, apresentando bexiga neurogênica e infecções urinárias de repetição, em que foi encontrado CE em ultrassonografia, sendo possível o tratamento adequado e resolução do quadro.

Emphysematous cystitis (EC) is a rare urinary tract infection, caused by the presence in the bladder of gas-producing bacteria, as Escherichia coli and Klebsiella pneumoniae. It is more common in women over 60 years and presentes as main risk factor decompensated diabetes mellitus. The diagnosis is only possible through imaging tests, since the symptoms are very similar to uncomplicated forms of urinary tract infection. Early antimicrobial treatment is important to reduce the serious complications associated with this pathology. It describes a typical clinical case of a female patient, decompensated diabetic, neurogenic bladder and recurrent urinary tract infection, where EC was found on ultrasonography, being possible the appropriate treatment and resolution of the condition.

New alternatives for the treatment of uncomplicated urinary tract infection, presentation of 2 clinical cases / Nuevas alternativas para el tratamiento de infección urinaria no complicada, presentación de 2 casos clínicos

Abstract The current perspective on the management of infectious diseases is a challenge for clinicians, because while new antibiotics are developed, bacteria improves its resistance system. That is why this study presents CANTHARIS 9 CH as an alternative treatment for urinary tract infection. This drug has an homeopathic use and it has been tested on humans as an urinary prophylactic. In this text, we present two cases of patients who voluntarily accept to receive this new protocol. Both cases show laboratory confirmation of infection, with quinolone resis tance, among others, and negativization post-treatment with CANTHARIS 9 CH. No side effects were reported in this sample.

Resumen La actual perspectiva en el manejo de enfermedades infecciosas es un reto para el clínico, en la medida en que se desarrollan nuevos antibióticos, las bacterias mejoran su sistema de resistencia. Por esto, este estudio presenta una alternativa al tratamiento de infección urinaria con CANTHARIS 9 CH, medicamento de uso homeopático que tiene estudios en humanos como profiláctico urinario. Se presentan dos casos de pacientes que aceptan voluntariamente recibir este nuevo protocolo. En ambos casos se muestra una confirmación microbiológica de la infección, con resistencia a quinolonas, entre otros, y negativización post tratamiento con el medicamento CANTHARIS 9 CH. No se reportaron efectos secundarios en esta muestra.

Detecting Bladder Biomarkers for Closed-Loop Neuromodulation: A Technological Review / 대한배뇨장애요실금학회지

Neuromodulation was introduced for patients with poor outcomes from the existing traditional treatment approaches. It is well-established as an alternative, novel treatment option for voiding dysfunction. The current system of neuromodulation uses an open-loop system that only delivers continuous stimulation without considering the patient’s state changes. Though the conventional open-loop system has shown positive clinical results, it can cause problems such as decreased efficacy over time due to neural habituation, higher risk of tissue damage, and lower battery life. Therefore, there is a need for a closed-loop system to overcome the disadvantages of existing systems. The closed-loop neuromodulation includes a system to monitor and stimulate micturition reflex pathways from the lower urinary tract, as well as the central nervous system. In this paper, we reviewed the current technological status to measure biomarker for closed-loop neuromodulation systems for voiding dysfunction.

Intermittent Self-catheterization in Older Adults: Predictors of Success for Technique Learning / 대한배뇨장애요실금학회지

PURPOSE: The main goal of this retrospective study is to explore the predictors of success in learning clean intermittent self-catheterization (CISC) in patients over 65 years of age. The secondary goal is to assess whether in this population, the risk of failure to perform CISC is greater, compared with patients under 65 with similar pathologies. METHODS: All patients older than 65 consulting between January 2011 and January 2016 for learning CISC were included. A control population younger than 65 matching with sex, body mass index, and pathology was selected. RESULTS: One hundred sixty-nine of the 202 patients (83.7%) over 65 succeeded in learning CISC. Obesity (P < 0.05), low pencil and paper test (PP test) (P < 0.01) and low functional independence measure (FIM) (P < 0.01) scores were risk factors of failure. No significant differences were found with sex or pathology. In multivariate analysis, low PP test perineum access (odds ratio [95% confidence interval], 2.30 [1.32–4.42]), low FIM motor (1.04 [1.01–1.08]), and FIM cognition (1.18 [1.03–1.37]) scores were independent factors of learning failure. Compared to control group, age over 65 was not predictive of failure (P=0.15). CONCLUSIONS: Our study shows that success in learning CISC does not depend on age but on difficulties in mobility, access to perineum and probably cognitive disorders.

It is located inside the bladder mucosa and submucosa. It has been found in patients of all ages, including children. To present the clinical and anatomopathological characteristics of a rare disease and the interest that it may have for in training residents, it was decided to present the case of a 21 year old black male patient, with a history of dysuria, Increased urinary frequency in the day, night and urgency, as well as repeated episodes of macroscopic hematuria, with clinical diagnosis of glandular cystitis confirmed by biopsy.

Long-term Outcomes of Augmentation Enterocystoplasty in Patients With End-Stage Bladder Diseases: A Single-Institute Experience Involving 102 Patients / 대한배뇨장애요실금학회지

PURPOSE: Augmentation enterocystoplasty (AE) has been shown to improve clinical symptoms in patients with end-stage bladder disease (ESBD). Herein, we report the long-term outcomes of a series of patients with different etiologies of ESBD who received AE. METHODS: We retrospectively reviewed 102 patients with ESBD who received AE at the Hualien Tzu Chi General Hospital from 1992 to 2014. ESBD in this study was defined as including neurogenic lower urinary tract dysfunction (NLUTD) due to spinal cord injury (SCI) or myelomeningocele, inflammatory bladder disease (IBD), ESBD occurring after pelvic cancer surgery, and other etiologies. Complications including active lower urinary tract problems and urinary tract infection (UTI), as well as patients’ self-reported satisfaction with the procedure, were evaluated. RESULTS: A total of 102 patients were included in the study. A majority of patients received AE for NLUTD (n=43), followed by IBD (n=38), ESBD after pelvic cancer surgery (n=15), and the other etiologies (n=6). Patients had a mean age of 39.4±18.7 years and were followed for a mean of 78 months. All patients had significantly increased cystometric bladder capacity and compliance at the time of follow-up. Fifty-four patients (52.9%) reported moderate to excellent satisfaction with the outcome, and there were no significant differences among the groups (P=0.430). The most common reason for dissatisfaction was the need for clean intermittent catheterization (CIC; 41.7%), followed by urinary incontinence (25.0%) and recurrent UTI (16.7%). CONCLUSIONS: AE is a safe and effective procedure for patients with ESBD. Postoperative urinary incontinence and UTI as well as the need for CIC may affect quality of life and decrease patient satisfaction.

The patients with DM were divided into DM course≥10 years group and DM course0.05). There were no statistical differences in volume leading to first bladder sensation (P>0.05). Conclusions MFR decrease detected with the technology of uroflowmetry specific bladder capacity may be widely used in screening early DCP.

Clinical significance of urodynamic detection in patients with diabetic cystopathy complicated with benign prostatic hyperplasia / 中国医师进修杂志

Objective To obtain reasonable treatment by urodynamic detection and analysis in patients with diabetic cystopathy (DCP) complicated with benign prostatic hyperplasia (BPH).Methods Sixty patients with DCP complicated with BPH were selected,among the total 32 patients (duration of diabetes ＞ 12 years,blood glucose control was not ideal) were recognized as experimental group,and 28 patients (duration of diabetes ≤ 8 years,blood glucose control was stable) were recognized as control group.Using the Laborie UDS-120XLT urodynamic detection instrument,the urodynamic was detected and the international prostate symptom score (IPSS) was evaluate,and the results were compared between the 2 groups.Results There was no statistical difference in residual urine volume between experimental group and control group [(146 ±71) ml vs.(160 ±64) ml,P ＞0.05].The maximum urinary flow-rate in experimental group was significantly lower than that in control group [(5.4 ± 2.0) ml/s vs.(8.0 ± 3.2) ml/s],the symptom total score of IPSS was significantly higher than that in control group [(25.8 ± 4.1) scores vs.(22.6 ±5.0) scores],there were statistical differences (P ＜0.01).The maximum bladder capacity,compliance,incipient micturition desire volume in experimental group were significantly lower than those in control group,there were statistical differences (P ＜ 0.01).Conclusions The influence of DCP on the function of the bladder in BPH patients is significant.Urodynamic detection can provide objective basis for the selection of therapeutic methods,suitable to be operated and forecast the postoperative effect.It has an important reference value in DCP complicated with BPH patients.

Establishment of diabetic cystopathy guinea pig model and its urodynamic evaluation / 中国组织工程研究

BACKGROUND:Diabetic cystopathy is one of the most common chronic diabetic complications. The establishment of animal models of diabetic cystopathy wil provide experimental animal platform for relevant research. OBJECTIVE:To establish a guinea pig model of diabetic cystopathy and to evaluate its urodynamic characteristics. METHODS:Fifty short-hair Britain female guinea pigs were randomly divided into two groups, 42 as the experiment group and the other 8 as the control group. The experiment group was intraperitoneal y injected with streptozotocin to induce diabetes. The control group received injection of blank citric acid buffered solution. Diabetic guinea pigs were detected by urinary dynamics test at 9 and 12 weeks. Diabetic guinea pigs were further assigned into diabetic cystopathy subgroup and compensated subgroup. The urodynamic parameters of three groups were compared. RESULTS AND CONCLUSION:Twenty of 42 guinea pigs were successful y induced diabetes by the injection of streptozotocin. At 9 weeks after the injection, bladder function compensation was present in six diabetic guinea pigs while bladder function was decompensated in another three diabetic guinea pigs. At 12 weeks, bladder function compensation was present in one diabetic guinea pig, while another eight guinea pigs were confirmed with diabetic cystopathy (88.89%). In the diabetic cystopathy subgroup, the residual urine volume was increased (0.72±0.08) mL, maximal detrusor pressure was decreased (0.63±0.05) kPa, maximum bladder capacity was increased (2.01±0.05) mL, and bladder compliance was increased (0.34±0.04) mL/kPa. There were significant differences compared with the compensated subgroup and the control group (P<0.001). Diabetic cystopathy occurs at 12 weeks after diabetic models are successful y established in guinea pigs, and urodynamic changes are mainly the increase of residual urine volume.

Objective To observe the clinical effect of doxazosin combined with diclofenac sodium in the treatment of bladder spasm after transurethral bipolar plasmakinetic prostatectomy (TUPKP).Methods 200 BPH patients undergoing TUPKP were randomly divided into 4 groups according to single-blind randomized controlled trial design:group A,group B,group C,group D (n =50,each).Patients in group A were given diclofenac sodium 100 mg,q12h,in anus after surgery and doxazosin 4 mg/d orally after anesthetic awareness.Patients in group B were given diclofenac sodium in anus 100 mg,q 12h in anus after surgery.Patients in group C were given doxazosin 4 mg/d orally after anesthetic awareness.Patients in group D were not given diclofenac sodium and doxazosin.Drugs were withdrawn 3 days after surgery.Results In group A,the average time of bladder spasm was (0.47±0.18) time,(0.35±0.16) time,(0.30±0.20) time at the 1st,2 nd,3 rd day respectively; the duration of bladder spasm was (3.2±1.5) min,(2.1±1.3) min,(1.4±1.2)min at the 1st,2nd,3th day respectively; the time of bladder perfusion clearance was (1.5± 0.3)days and the time of urethral catheter removal was (4.0±0.5) days.There were significant differences in above observed values between group D and the other groups (all P＜0.05).Conclusions Doxazosin combined with diclofenac sodium therapy is effective in the treatment of bladder spasm after bipolar transurethral plasmakinetic prostatectomy.

Transvaginal Cystocele Repair by Purse-String Technique Reinforced with Three Simple Sutures: Surgical Technique and Results / 대한배뇨장애요실금학회지

PURPOSE: Different techniques for cystocele repair including the conventional anterior colporrhaphy and mesh technique are known. Our goal was to evaluate the anatomical success and safety of our method of transvaginal anterior vaginal wall repair by the purse-string technique reinforced with three simple additional sutures in the repair of cystocele over a 4-year follow-up period. METHODS: This was a retrospective review of 69 consecutive patients (grades 2 to 4) who underwent the above operations between 2001 and 2011, including their success rates as assessed by use of the Baden-Walker halfway classification system. RESULTS: Of the patients, 62 patients (98%) were completely cured of cystocele and 1 patient showed grade 2 cystocele recurrence that required no further treatment. Two patients with grade 4 cystocele were completely cured. There was no vaginal erosion related to the cystocele repair. CONCLUSIONS: Transvaginal anterior colporrhaphy by a purse-string technique reinforced with simple additive sutures appears to be a simple, safe, and easily performed approach in cystocele repair. There is no need for other material for reinforcement, even in high-grade cystocele, which is an advantage of our technique.

Vesico-Acetabular Fistula and Urolithiasis in the Hip Joint Cavity due to Persistent Bladder Entrapment after Acetabular Fracture

We report a rare case of vesico-acetabular fistula due to an improperly treated pelvic fracture with urinary stone formation in the joint cavity. This complication was related to an unrecognized mechanism of bladder wall entrapment in the acetabular floor defect during weight bearing. This situation led to several mistreatment decisions in our case and should be always considered by urologists dealing with patients after major pelvic trauma. In this case report, we analyze the publications related to this problem, discuss the main mechanisms of bladder wall damage after acetabular fracture, and propose tips for diagnosis and treatment.

O uso da toxina botulínica na síndrome da bexiga hiperativa / The use of botulinum toxin in the treatment of overactive bladder syndrome

Nos últimos anos, a toxina botulínica (BTX) vem surgindo como uma opção para tratamento de algumas disfunções do trato urinário, como, por exemplo, a síndrome da bexiga hiperativa. Ela foi descrita pela primeira vez por Emile Pierre Marie van Ermengem em 1897 e desde então, vem se tornando uma importante arma terapêutica. Dos sete tipos distintos de BTX, somente os tipos A e B estão disponíveis para uso clínico. Seu mecanismo de ação consiste em causar paralisia flácida ao ser injetada no músculo, inibindo a ação da acetilcolina nas junções colinérgicas pré-sinápticas. Seu efeito é transitório e dose-dependente. A bexiga hiperativa é doença comum, que atinge cerca de 17% da população européia e norteamericana. Geralmente, ela é tratada de forma conservadora, principalmente com drogas antimuscarínicas, que são as drogas de escolha. Realizamos revisão da literatura, por meio do PubMed com o objetivo de verificar as indicações desta medicação, sua posologia, técnica de aplicação, efeitos colaterais, complicações e eficácia nas pacientes portadores de bexiga hiperativa neurogênica e idiopática. Foi concluído que a BTX parece ser uma opção de tratamento segura e eficaz para estas pacientes, porém mais estudos precisam ser realizados, principalmente para os portadores de bexiga hiperativa idiopática refratária aos tratamentos convencionais.

In the past few years, botulinum toxin (BTX) is being recognized as an option for the treatment of the urinary tract dysfunctions like overactive bladder syndrome. It was first isolated by Emile Pierre Marie van Ermengem in 1897 and, since then it is becoming an important treatment option. Of the seven distinct types of the toxin, only types A and B are available for clinical use. When injected into the muscle, the toxin acts by inhibiting acetylcholine release at the presynaptic cholinergic neuromuscular junction. Its effect is transient and dose-related. The overactive bladder is a commun disease that affects about 17% of the population in Europe and in the United States. Usually, the treatment is conservative and the mainstay is anticholinergic drugs. It was reviewed the literature using PubMed with the objective of verifying the indications, posology, technique of administration, side effects, complications and efficacy in patients with neurogenic and idiopathic overativity bladder. It was concluded that BTX seems to be a treatment option, which is safe and effective for these patients, but more studies are needed especially on the idiopathic overactive bladder.
