ABSTRACT Purpose: We assessed the efficacy and safety of a single injection of three bulking agents over the short- and long-term follow-ups in rabbits. Dermal and preputial matrices were compared with Deflux (DxHA) injection. Material and methods: Twenty-four rabbits were divided into three groups. Group I (n=8) underwent the injection of a lyophilized dermal matrix (LDM) beneath the seromuscular layer of the bladder wall. Rabbits in group II (n=8) were injected with lyophilized preputial matrix (LPM). Rabbits of group III (n=8) were injected with DxHA as the control group. They were followed up for 1 and 6 months after the injection. Subcutaneous injection of all bulking agents was also performed in nude mice. Biopsies were stained with LCA (leukocyte common antibody), CD68, CD31, and CD34. Scanning electron microscopy (SEM) and MTT assay were also performed. Results: Immunohistochemistry staining with CD68 and LCA revealed higher inflammation grade in LDM as compared with LPM and DxHA. Fibrosis grade was also higher in LDM both in short- and long-term follow-ups. However, no significant difference was detected in CD31 and CD34 staining between control and experimental groups. SEM analysis showed that the particle size of LPM was more similar to DxHA. MTT assay revealed that cell proliferation was similar in DxHA, LDM, and LPM. In-vivo assay in nude mice model showed more promising results in LPM as compared with LDM. Conclusion: The long-term results demonstrated that LPM was more similar to Deflux with the least local tissue reaction, inflammation, and fibrosis grade.

ABSTRACT Hypothesis: Endoclip can be used as fiducial marker in urology. Objective: To assess the feasibility, cost effectiveness and reliability of endoclips as novel fiducial markers in precision radiotherapy, as part of a trimodality bladder-preserving treatment (TBPT) of muscle-invasive bladder carcinoma. Materials and Methods: This retrospective study was performed at Weifang People's Hospital (Weifang, China) from January 2015 to June 2018. A total of 15 patients underwent TBPT. Endoclips were applied to healthy edges of the resected bladder wall as novel fiducial markers. Radio-sensitizing chemotherapy and routine precision radiotherapy were given. The number and position of the endoclips during radiotherapy sessions were monitored. Complications and tumor recurrence were analyzed. Results: The mean age (±standard deviation) of the patients was 67±10 years (range 46-79). There were 3 females and 12 males. Forty-nine endoclips were applied in all patients (3.3±0.8). The tumor was completely visibly resected in all patients. The number of endoclips remained the same through the planned last radiotherapy session (3.3±0.8), i.e., none were lost. All endoclips were removed after the last radiotherapy session. The average number of follow-up months was 38.9±13.2 (range 11-52). There were no procedure-related complications at discharge or follow-up. At one-year, overall recurrence-free survival was 93.3%. Two patients had recurrences at 18 months and 10 months after TBPT, respectively, and salvage radical cystectomy was performed with no further recurrences. Another patient died due to metastasis 9 months after the completion of therapy. Conclusions: Endoclips are reliable, safe and cost-effective as novel fiducial markers in precision-radiotherapy post-TBPT.

O acretismo placentário consiste na aderência anormal da placenta na parede uterina. Ao aderir-se diretamente ao miométrio, denomina-se placenta acreta; ao estender-se mais profundamente, placenta increta, e ao invadir a serosa uterina ou órgãos adjacentes, percreta. O fator de risco mais frequente constitui cesarianas anteriores. Paciente 27 anos, G3P1CA1 (cesariana há 8 anos/ parto prematuro 25 sem há 4 anos), IG: 25sem3d; com alteração da vitalidade fetal e placenta prévia com sinais de acretismo (sugerindo placenta percreta). Foi indicada a interrupção da gestação com 27 semanas e 1 dia. No período intraoperatório foi evidenciada, por meio de ultrassom, presença de acretismo placentário com invasão miometrial e invasão de serosa vesical sendo posteriormente realizado a histerectomia subtotal e rafia das lacerações da mucosa vesical. A placenta percreta é mais frequente em grávidas com placenta prévia no local da cicatriz de cesariana e o órgão mais frequentemente acometido é a bexiga; estando associada a maior morbimortalidade materna. O diagnóstico definitivo é anatomopatológico, porém é presumível durante a cirurgia abdominal com a visualização da invasão placentária, devendo ser confirmado por Histopatologia.

Placental accretism consists of abnormal placental adherence to the uterine wall. When adhering directly to the myometrium it is called placenta accreta; when extending more deeply, placenta increta; and when invading the uterine serosa or adjacent organs, percrete. The most frequent risk factor is previous cesarean sections. The patient is 27 years old with altered fetal vitality and placenta previa with signs of accreation (suggesting percretal placenta). Pregnancy termination at 27 weeks and one day was indicated. In the intraoperative period, the presence of placental accretion with myometrial invasion and bladder serous invasion was evidenced by ultrasound, with subtotal hysterectomy and raffia of lacerations of the bladder afterwards. The percretal placenta is more frequent in pregnant women with placenta previa at the site of the scar of a cesarean section and the organ most frequently affected is the bladder; being associated with higher maternal morbidity and mortality. The definitive diagnosis is anatomopathological, but it is presumed during abdominal surgery with the visualization of the placental invasion and must be confirmed by Histopathology

OBJECTIVES: Whole genome expression profiles allow the stratification of bladder urothelial carcinoma into basal and luminal subtypes which differ in histological patterns and clinical behavior. Morpho-molecular studies have resulted in the discovery of immunohistochemical markers that might enable discrimination between these two major phenotypes of urothelial carcinoma. METHODS: We used two combinations of immunohistochemical markers, i.e., cytokeratin (CK) 5 with CK20 and CK5 with GATA3, to distinguish subtypes, and investigated their association with clinicopathological features, presence of histological variants, and outcomes. Upon searching for tumor heterogeneity, we compared the findings of primary tumors with their matched lymph node metastases. We collected data from 183 patients who underwent cystectomy for high-grade muscle-invasive urothelial carcinoma, and representative areas from the tumors and from 76 lymph node metastasis were organized in tissue microarrays. RESULTS: Basal immunohistochemical subtype (CK5 positive and CK20 negative, or CK5 positive and GATA3 negative) was associated with the squamous variant. The luminal immunohistochemical subtype (CK5 negative and CK20 positive, or CK5 negative and GATA3 positive) was associated with micropapillary and plasmacytoid variants. Remarkably, only moderate agreement was found between the immunohistochemical subtypes identified in bladder tumors and their lymph node metastasis. No significant difference in survival was observed when using either combination of the markers. CONCLUSION: This study demonstrates that these three routinely used immunohistochemical markers could be used to stratify urothelial carcinomas of the bladder into basal and luminal subtypes, which are associated with several differences in clinicopathological features.

BACKGROUND@#Since 2019, a novel coronavirus named 2019 novel coronavirus (2019-nCoV) has emerged worldwide. Apart from fever and respiratory complications, acute kidney injury has been observed in a few patients with coronavirus disease 2019. Furthermore, according to recent findings, the virus has been detected in urine. Angiotensin-converting enzyme II (ACE2) has been proposed to serve as the receptor for the entry of 2019-nCoV, which is the same as that for the severe acute respiratory syndrome. This study aimed to investigate the possible cause of kidney damage and the potential route of 2019-nCoV infection in the urinary system.@*METHODS@#We used both published kidney and bladder cell atlas data and new independent kidney single-cell RNA sequencing data generated in-house to evaluate ACE2 gene expression in all cell types in healthy kidneys and bladders. The Pearson correlation coefficients between ACE2 and all other genes were first generated. Then, genes with r values larger than 0.1 and P values smaller than 0.01 were deemed significant co-expression genes with ACE2.@*RESULTS@#Our results showed the enriched expression of ACE2 in all subtypes of proximal tubule (PT) cells of the kidney. ACE2 expression was found in 5.12%, 5.80%, and 14.38% of the proximal convoluted tubule cells, PT cells, and proximal straight tubule cells, respectively, in three published kidney cell atlas datasets. In addition, ACE2 expression was also confirmed in 12.05%, 6.80%, and 10.20% of cells of the proximal convoluted tubule, PT, and proximal straight tubule, respectively, in our own two healthy kidney samples. For the analysis of public data from three bladder samples, ACE2 expression was low but detectable in bladder epithelial cells. Only 0.25% and 1.28% of intermediate cells and umbrella cells, respectively, had ACE2 expression.@*CONCLUSION@#This study has provided bioinformatics evidence of the potential route of 2019-nCoV infection in the urinary system.

To study the mechanism of polysaccharides from seeds of Vaccaria segetalis( PSV) in the treatment of bacterial cystitis through the NLRP3 inflammasome pathway. The rat model of urinary tract infection was used and treated with PSV,and the urine and bladders were collected. The level of interleukin-10( IL-10) in rat urine was detected by enzyme linked immunosorbent assay( ELISA). Western blot and immunofluorescence staining were used to detect the expressions of sonic hedgehog( SHH) and NLRP3 inflammasome [NOD-like receptor thermoprotein domain 3( NLRP3),apoptosis associated speck like protein( ASC) and pro-caspase-1]. The expression of Toll-like receptor pathway was detected by RT-PCR. The death of 5637 cells induced by uropathogenic Escherichia coli( UPEC) and lactate dehydrogenase( LDH) release were evaluated using live/dead staining. The results showed that in the rat bladder,the expressions of SHH,NLRP3 inflammasomes and Toll-like receptors were significantly up-regulated,and NLRP3 inflammasomes were significantly activated by UPEC infection. The administration with PSV could significantly increase the concentration of IL-10 in urine,inhibit the expressions of SHH,NLRP3 inflammasomes and Toll-like receptors in bladder,and inhibit the activation of NLRP3 inflammasomes. A large number of 5637 cells were dead after UPEC infection and caused LDH production. PSV could significantly inhibit the death of 5637 cells and the release of LDH. In conclusion,PSV could inhibit the expression and activation of NLRP3 inflammasomes by inhibiting the Toll-like receptor pathway,thereby mitigating the bladder injury.

Objectives: This study aimed to assess the accuracy of post-void residual (PVR) urine volume measurements in patients with moderate bladder outlet obstruction. Materials and Methods: This prospective observational study was conducted between January and December 2019. The inclusion criteria were male patients with symptoms of moderate bladder outlet obstruction. On the other hand, patients with a history of diabetes, symptoms of urinary tract infection, and positive urine for pyuria, as well as patients using medications, such as diuretics, alpha-blockers, and anticholinergic drugs, were excluded. The patients were asked to drink 1000 mL of water one to two hours before the initial ultrasound scan. Pre-void bladder capacity was measured, followed by a post-void ultrasound for residual urine volume measurement at three intervals: immediately after voiding, 15-20 minutes after the first void, and one week later with an empty bladder. Assessment of per-void capacity was carried out, based on the patient's subjective sensation of bladder fullness (a strong desire to void). Results: A total of 78 male patients, with the mean age of 60 years, were included in this study (27 cases in group I; 37 cases in group II; and 14 cases in group III). The mean PVR volume was 92 mL in the first measurement, 62 mL in the second measurement, and 60 mL in the third measurement. Significant differences were found between the first and second PVR measurements and between the first and third PVR measurements (P<0.05). However, no significant difference was found between the second and third PVR measurements (P=0.107). On the other hand, significant differences were found between groups I and II and between groups I and III (P<0.05) in the three PVR measurements. Nevertheless, there was no significant difference between groups II and III in the three PVR measurements (P=0.204, 0.56, and 0.487 for the first, second, and third PVR measurements, respectively). Conclusion: A bladder ultrasound must be performed and interpreted carefully to avoid further unnecessary medications, investigations, or procedures. We recommend a second PVR measurement in patients with bladder outlet obstruction. Also, it is suggested to conduct similar studies in different conditions to confirm our findings.

Diabetes Mellitus (DM) is a condition marked by hyperglycaemia that causes systemic complications, including urinary vesicle dysfunction due to oxidative stress. Further, antioxidants, as well as alpha lipoic acid (ALA), may be a response to this pathological condition. The present study verified the action of ALA as a supplement in ration on glycemia and urinary vesicle structures of rats induced by streptozotocin. The rats were divided into 4 groups: Control (CG), Alpha Lipoic (ALAG), Diabetic control (DCG), and the Diabetic alpha lipoic (DALAG) group. For induction, the diabetic groups were initially induced with streptozotocin (dose 60 mg/kg). Subsequently, group glycemia was evaluated weekly. After 8 weeks, the rats were euthanized and the bladder was collected. The bladders were histologically processed and the slides were stained with Masson's Trichrome for the histomorphometry of epithelial height, connective and muscular tissue and coloration of PicroSirius Red for further analysis of collagen fibers of the bladder. The data of the glycemia demonstrated an inferior median in DALAG compared to DGC (p<0.01). The epithelial height and percentage of the muscle tissue were greater in DALAG compared to the DGC, but not significant. However, GDAL showed improvement in the organization of collagen fibers. In conclusion, bladder the morphology alterations caused by DM were not alleviated by the administration of ALA in 8 weeks of the experiments.

La diabetes mellitus (DM) es una afección marcada por hiperglucemia que causa complicaciones sistémicas, incluida la disfunción de la vejiga urinaria debido al estrés oxidativo. Además, los antioxidantes, así como el ácido alfa lipoico (ALA), pueden ser una respuesta a esta condición patológica. El presente estudio verificó la acción de ALA como suplemento en la ración sobre la glucemia y las estructuras de la vejiga urinaria de ratas inducidas por estreptozotocina. Las ratas se dividieron en 4 grupos: control (CG), alfa lipoico (ALAG), control diabético (DCG) y el grupo diabético alfa lipoico (DALAG). Para la inducción, los grupos diabéticos se aplicó estreptozotocina (dosis 60 mg/kg). Posteriormente, la glucemia grupal se evaluó semanalmente. Después de 8 semanas, las ratas se sacrificaron y se retiró la vejiga urinaria. Las vejigas se procesaron histológicamente y las muestras se tiñeron con tricromo de Masson para la histomorfometría y así evaluar la altura epitelial, el tejido conectivo y muscular. Además se tiñeron cond PicroSirius Red para un análisis posterior de las fibras colágenas de la vejiga urinaria. Los datos de la glucemia demostraron una mediana inferior en DALAG en comparación con DGC (p <0,01). La altura epitelial y el porcentaje de tejido muscular fueron mayores en DALAG en comparación con el DGC, pero no estadísticamente significativos. Sin embargo, GDAL mostró una mejora en la organización de las fibras de colágeno. En conclusión, la morfología de las alteraciones de la vejiga causada por DM no se alivió con la administración de ALA en 8 semanas de estudio.

Objetivo: Avaliar a relação de custo-efetividade de mirabegrona como tratamento de primeira escolha de pacientes adultos com síndrome da bexiga hiperativa (SBH) comparada a antimuscarínicos orais comumente prescritos no manejo dessa condição. Métodos: O modelo de Markov foi utilizado, com ciclos mensais e horizonte temporal de um ano, para analisar a relação de custo-efetividade de mirabegrona em comparação a tolterodina, oxibutinina, darifenacina e solifenacina. Os pacientes iniciaram o modelo em tratamento com mirabegrona ou um dos comparadores, sendo distribuídos em cinco níveis de gravidade da doença, de acordo com a frequência miccional e número de episódios de incontinência, e a cada ciclo mensal poderiam melhorar, piorar ou permanecer no mesmo nível de severidade do ciclo anterior. Os resultados foram apresentados por meio de uma razão de custo-efetividade incremental. Resultados: Considerando a perspectiva do sistema de saúde suplementar, o custo total do tratamento com mirabegrona foi de R$ 2.455,26 e os parâmetros de efetividade em 0,491 e 0,498 (melhora na gravidade da incontinência e frequência miccional, respectivamente), sendo mais efetivo que os comparadores. Com relação à perspectiva pública, foi estimado um custo com o tratamento de R$ 1.396,01, com características similares de efetividade. De maneira geral, o tratamento com mirabegrona foi dominante quando comparado à tolterodina e custo-efetivo na comparação com os demais antimuscarínicos, em ambas as perspectivas analisadas. Conclusão: Mirabegrona demonstrou ser a melhor opção para tratamento de primeira escolha da SBH com potencial de redução de custos ao longo do tempo, tanto para o sistema público quanto para o sistema de saúde suplementar brasileiro.

Objective: To assess the cost-effectiveness of mirabegron as first-choice treatment in adult patients with of overactive bladder (OAB) compared to oral antimuscarinics, usually prescribed for this condition. Methods: A Markov model has been adopted, with monthly cycles and a one-year time horizon, to analyze the cost-effectiveness of mirabegron compared to antimuscarinic agents: tolterodine; oxybutynin; darifenacin; and solifenacin. The model started with patients receiving treatment with mirabegron or one of the comparators and then, they were assigned to five disease severity levels according to micturition frequency and number of incontinence episodes, and within each monthly cycle they could improve, worsen or remain at the same symptom severity level. Results were presented using an incremental cost-effectiveness ratio. Results: Considering the Brazilian private perspective, treatment with mirabegron resulted in a total cost of R$ 2,455.26 and effectiveness parameters at 0.491 and 0.498 (improvement in incontinence severity and micturition, respectively), being more effective than the comparators. Regarding the Brazilian public perspective, treatment with mirabegron resulted in a total cost of R$ 1,396.01 with similar effectiveness estimation. In general, a dominance was observed when mirabegron was compared to tolterodine and a cost-effectiveness profile against the other muscarinic antagonists, considering both health perspectives. Conclusion: Mirabegron has proven to be the best option for OAB first-line treatment with potential cost savings over time for both the public and private health care systems in Brazil.

Introducción: La ectopia renal cruzada fusionada, es una anomalía congénita infrecuente, que acontece durante la migración fisiológica de dichos órganos en la etapa embrionaria. Objetivo: Describir detalles clínicos e imaginológicos de un nuevo caso de ectopia renal cruzada fusionada. Caso clínico: Paciente masculino de 48 años de edad, con antecedentes de hiperplasia prostática, con tratamiento de terazosina. Presentó retención completa de orina por lo cual se le colocó sonda uretral. El ultrasonido abdominal reportó que el riñón izquierdo era de ecoestructura, tamaño y posición normales, pero el derecho no estaba en la localización normal y se sospechó que estaba situado en la región del mesogastrio. La vejiga era normal y la próstata tenía un volumen de 87 cm3. La tomografía axial computarizada abdominal contrastada, confirmó que se trataba de una ectopia renal derecha cruzada fusionada, en el polo inferior del riñón ortotópico, en forma de "J". Se intentó retirar la sonda uretral en dos ocasiones y volvía a obstruirse, por lo cual se decidió la terapéutica quirúrgica definitiva. En el chequeo preoperatorio todos los estudios de la analítica sanguínea fueron normales. Al paciente se le realizó la adenomectomía retropúbica. Evolucionó satisfactoriamente. El estudio histopatológico de la pieza quirúrgica informó hiperplasia prostática. Conclusiones: La ectopia renal cruzada fusionada es infrecuente. El diagnóstico de certeza se obtiene mediante la tomografía axial computarizada abdominal contrastada(AU)

Introduction: Crossed-fused renal ectopia is a rare congenital anomaly, which occurs during the physiological migration of these organs in the embryonic stage. Objective: To describe clinical and imaginological details of a new case of crossed-fused renal ectopia. Case report: 48-year-old male patient, with a history of prostatic hyperplasia, with terazosin treatment. He had complete retention of urine for which urethral catheter was placed. Abdominal ultrasound reported that the left kidney was of normal structure, size and echo, but the right one was not in the normal location and was suspected of being located in the mesogastrium region. The bladder was normal and the prostate had a volume of 87 cm3. Contrast abdominal computed tomography confirmed that it was a fused right renal ectopia, in the lower pole of the orthotopic kidney, in the form of "J". An attempt was made to remove the urethral catheter twice and it became blocked again, so the definitive surgical therapy was decided. In the preoperative check-up, all blood test studies were normal. The patient underwent retropubic adenomectomy. It evolved satisfactorily. Histopathological study of the surgical specimen reported prostatic hyperplasia. Conclusions: Crossed-fused renal ectopia is uncommon. The diagnosis of certainty is obtained by contrasted abdominal computed tomography(AU)

Los tumores vesicales no músculo-invasivos se definen como lesiones papilares limitadas a la mucosa vesical o que invaden la lámina propia, además de los tumores de morfología plana y alto grado limitados a la mucosa (carcinoma in situ [CIS]). La confirmación diagnóstica se produce tras el análisis histológico de la muestra obtenida en la resección transuretral (RTU) de vejiga, que en los tumores Ta-T1 requiere la resección completa de todas las lesiones, incluyendo parte del músculo detrusor, lo que constituye, también, el método terapéutico. En el caso del CIS, que puede simular inflamación o no ser visible en la cistoscopia, son necesarias múltiples biopsias aleatorias de la vejiga. La perforación iatrogénica de la vejiga es el segundo evento adverso más frecuente del mencionado procedimiento; esta solución de continuidad en la pared puede dar lugar a la migración de grasa hacia el interior de la vejiga, que en las pruebas de imagen se traduce en la formación de un nivel líquido-grasa intravesical, hallazgo infrecuente, que a su vez posee un amplio diagnóstico diferencial, que abarca causas primarias, infecciosas y traumáticas, pero no previamente descrito como una complicación de la RTU. Se presenta el caso de un paciente asintomático con un nivel líquido-grasa intravesical secundario a perforación extraperitoneal de vejiga, tras la resección transuretral de un carcinoma urotelial no músculo-invasivo en la cúpula vesical.

Non-muscle-invasive bladder tumours are defined as papillary lesions limited to the bladder mucosa or invading the lamina propia, in addition to flat morphology and high-grade tumors limited to the mucosa (carcinoma in situ [CIS]). Diagnostic confirmation occurs after histological analysis of the sample obtained in the transurethral resection of the bladder (TURB), which in Ta-T1 tumours requires complete resection of all lesions, including part of the detrusor muscle, being in these cases also the therapeutic method. In the case of CIS, which may simulate inflammation or not be visible in cystoscopy, multiple random bladder biopsies are necessary (2). Iatrogenic bladder perforation is the second most frequent adverse event of this procedure; This solution of continuity in the wall can lead to the migration of fat into the bladder, which in imaging tests results in the formation of an intravesical fat-fluid level, a rare finding, which in turn has a broad differential diagnosis that covers primary, infectious and traumatic causes, but not previously described as a complication of TURB. We report the case of an asymptomatic patient with presence of intravesical fat-fluid, secondary to extra-peritoneal bladder perforation, after transurethral resection of a non-muscleinvasive urothelial carcinoma in the bladder dome.

Introducción. Cerca del 15 % de los pacientes con insuficiencia renal crónica terminal tienen alteraciones de las vías urinarias inferiores. Estas anomalías eran consideradas una contraindicación para el trasplante renal. Por lo anterior, el objetivo del presente trabajo es describir el comportamiento sociodemográfico y clínico de los pacientes trasplantados renales con ureterostomía cutánea como técnica de derivación definitiva de las vías urinarias. Métodos. Se realizó un estudio descriptivo, longitudinal y retrospectivo de los pacientes trasplantados renales con vejiga anormal y ureterostomía cutánea, entre enero de 1973 y octubre de 2012.Resultados. En 4.294 trasplantes renales, se practicaron 24 (0,55 %) ureterostomías, 19 (79,1 %) como técnica inicial y 5 por falla de la ureteroneocistostomía. Diez (41,7 %) ureterostomías fallaron, la mayoría (8 casos) por estenosis. Se presentó infección urinaria en 20 pacientes y la mortalidad fue del 8,3 % (2/24). El 50 % (12/24) de los pacientes con trasplante de riñón estuvieron libres de infección urinaria durante el primer año. La supervivencia del riñón trasplantado fue de 93,8 % (23/24) a los 18 meses, de 85,9 % (20/24) a los 36 meses y de 66,7 % (16/24) a los 50 meses de seguimiento. La supervivencia de los injertos con ureterostomía sin infección fue del 100 % durante el periodo de seguimiento, mientras que la supervivencia de los riñones con infección urinaria fue de 93 % (23/24) a los 18 meses, de 76 % (18/24) a los 36 meses y de 54 % (13/24) a los 50 meses (p=0,235). Conclusiones. La ureterostomía cutánea es una alternativa segura para la derivación urinaria en pacientes tras-plantados renales con alteraciones de la vejiga que no permite su uso o preparación antes del trasplante

Introduction. About 15% of patients with end-stage chronic renal failure have lower urinary tract abnormalities. These abnormalities were considered a contraindication for kidney transplantation. Therefore, the objective of the present work is to describe the sociodemographic and clinical behavior of renal transplant patients with skin ureterostomy as a definitive urinary tract bypass technique.Methods. A descriptive, longitudinal and retrospective study of renal transplant patients with abnormal bladder and skin ureterostomy was conducted between January 1973 and October 2012.Results. We performed 24 (0.55%) ureterostomies in 4.294 kidney transplants. Nineteen (79.1%) were used as first and definitive urinary diversion, and five were ureteroneocystostomies that failed and required ureterostomy as alternative diversion. Ten (41.7%) ureterostomies failed, most (eight cases) from stenosis. Urinary tract infection (UTI) were present in 20 patients and mortality was 8.3% (2/24); 50% (12/24) of kidney transplants were free of urinary tract infection during the first year. The survival of the transplanted kidney was 93.8% (23/24) at 18 months, 85.9% (20/24) at 36 months, and 66.8% (16/24) at 50 months of follow up. The survival of grafts with ureterostomy without urinary tract infection were 100% during the follow-up period, while the survival of the kidneys with UTI was 93% (23/24) at 18 months, 76% (18/24) at 36 months, and 54% (13/24) at 50 months (p=0.235).Conclusions. Cutaneous ureterostomy is a safe alternative for urinary diversion in transplanted renal patients with bladder abnormalities that cannot be prepared or used for a routine diversion before transplantation

OBJECTIVE@#To explore the preventive effect of acupuncture at Ciliao (BL 32) on postpartum urinary retention as well as the time and volume of the first urination after delivery in elderly parturient women undergoing vaginal delivery.@*METHODS@#A total of 180 elderly parturient women (≥35 years old) undergoing vaginal delivery were randomly divided into a blank control group, a conditional control group and an observation group, 60 cases in each group. The patients in the blank control group were treated with routine nursing plan; based on the treatment of the blank control group, the patients in the conditional control group were treated with additional intervention measures such as applying hot towel on the bladder and fingers pressing to stimulate urination; based on the treatment of the blank control group, the patients in the observation group were treated with acupuncture at bilateral Ciliao (BL 32) one hour after delivery for 20 min (the acupuncture was given only once). The incidence rate of postpartum urinary retention as well as the time and volume of the first urination among the women without urinary retention were observed; the satisfaction rate of the 3 groups was recorded.@*RESULTS@#The incidence rate of postpartum urinary retention in the observation group was 5.0% (3/60), which was significantly lower than 26.7% (16/60) in the blank control group (<0.01) and 16.7% (10/60) in the conditional control group (<0.05); the incidence rate of postpartum urinary retention in the conditional control group was significantly lower than that in the blank control group [16.7% (10/60) vs 26.7%(16/60), <0.05]. In the elderly women without urinary retention, the first urination time in the observation group was significantly earlier than that in the blank control group and conditional control group (<0.01), and the first urination time in the conditional control group was earlier than that in the blank control group (<0.01). The volume of first urination in the observation group was higher than that in the blank control group and the conditional control group (<0.05, <0.01). The satisfaction rates in the observation group and conditional control group were higher than that in the blank control group (<0.01).@*CONCLUSION@#Acupuncture at Ciliao (BL 32) could effectively prevent the postpartum urinary retention, improve the time and volume of the first urination in elderly parturient women undergoing vaginal delivery.

OBJECTIVE@#To reconstruct a three-dimensional model of female urinary system based on magnetic resonance imaging (MRI) and tomography angiography (CTA) data.@*METHODS@#MRI and CTA datasets were collected from 20 patients in our department in 2018 for reconstructing 3D models of the bladder urethra in resting state using Mimics19.0 software combined with engineering software. The metric parameters of the bladder urethra were analyzed in the reconstructed 3D model.@*RESULTS@#The bladder and urethra were successfully reconstructed using 10 MRI datasets, and the kidney, ureter and bladder were reconstructed using 10 CTA datasets. Using engineering software, we measured a number of cysto-urethral geometric parameters, including the cysto-urethral posterior angle (151.1±17.9°), beta angle (137.3±14.0°), urethral pubic angle (47.8± 12.1°), urethral tilt angle (21.5±7.3°), alpha angle (83.8±13.8°), the posterior pubic space (15.3±3.0 mm), and the urethral striated muscle thickness (2.6±0.6 mm).@*CONCLUSIONS@#Three-dimensional reconstruction of the anatomical model of the human urinary system provides a platform for studying the fine anatomy of the female urinary system and allows measurement of multiple parameters to better understand the functional differences of the bladder and urethra in different populations.
