Persistencia de uraco en paciente joven. Reporte de caso / Persistence of urachus in a young patient. Case report

Introducción. Durante el desarrollo embrionario normal, se espera que el denominado uraco o ligamento umbilical mediano se oblitere a las 32 semanas de gestación. Ante una obliteración incompleta surgen las diferentes anomalías, siendo las más frecuentes el quiste y la fístula urinaria umbilical. El objetivo de este artículo fue presentar el caso de una paciente joven, sin comorbilidades, con quiste de uraco. Caso clínico. Mujer indígena de 19 años que consultó por dolor leve en hipogastrio, asociado a síntomas urinarios y distensión abdominal. Se sospechó en primera instancia cólico renal, pero ante hallazgos ecográficos de masa infraumbilical y reactantes de fase aguda elevados, la impresión diagnóstica cambió a sepsis secundaria a absceso intraabdominal. Posterior a tomografía y cistoscopía con calibración uretral se identificó pequeño divertículo en cúpula vesical, que sugirió el diagnóstico de uraco persistente, por lo que la paciente fue llevada a intervención quirúrgica para su resección, con evolución favorable. Discusión. El quiste de uraco es una anormalidad infrecuente, en su mayoría asintomática y generalmente de hallazgo incidental en la población anciana, por lo que se requiere de imágenes y manejo multidisciplinar para su correcto diagnóstico y abordaje. Conclusión. Son pocos los casos de uraco persistente reportados, y mucho menos en el sexo femenino. Dada la posibilidad de complicaciones tardías es importante el seguimiento para su manejo. Este caso se ha controlado de manera ambulatoria por 2 años

Introduction. During normal embryonic development, it is expected that the so-called urachus or median umbilical ligament will be obliterated at 32 weeks of gestation. In the face of incomplete obliteration, the different anomalies of the urachus arise. The most frequent anomaly of the urachus is the cyst followed by the umbilical urinary fistula. The objective of this article was to present the case of a young patient without comorbidities with urachal cyst. Clinical case. A 19-year-old indigenous woman consulted for mild hypogastric pain associated with urinary symptoms and abdominal distension. Renal colic was suspected at first, but due to ultrasound findings of an infraumbilical mass and high acute phase reactants, the diagnostic impression changed to sepsis secondary to an intra-abdominal abscess. After tomography and cystoscopy with urethral calibration, a small diverticulum was identified in the bladder dome, suggesting a diagnosis of persistent urachus, for which the patient was taken to surgery for its resection, with favorable evolution. Discussion. The urachal cyst is a rare abnormality, mostly asymptomatic and usually incidental finding in the elderly population. Imaging and multidisciplinary management are required for its correct diagnosis and approach. Conclusion. There are few reported cases of persistent urachus and much less in females. Given the possibility of late complications, follow-up is important for its management, in this case we have carried out control for 2 years

Dynamic cystoscopy to optimize preoperative assessment of bladder endometriosis

ABSTRACT Purpose Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. Materials and Methods This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. Results We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.

Open surgery for urethral foreign body / Tratamiento quirúrgico convencional de cuerpo extraño uretral

Abstract The introduction of foreign bodies in the urethra are uncommon. Given its rarity, the approach to this condition is not standardized but it is highlighted that minimally invasive procedures should be prioritized depending on its feasibility. In the present study, we report a case of a 60-year-old male patient with bipolar disorder and a foreign body impacted in the bulbar urethra with open surgical resolution after a failed endoscopic treatment. We perform an analysis into the diagnostic and therapeutic methods used, with postopera tive results.

Resumen La introducción de cuerpos extraños uretrales es poco frecuente, razón por la cual, la mayoría de las publicaciones disponibles en la literatura son reportes de casos aislados o pequeñas series con gran heteroge neidad. Existen distintas aproximaciones frente a esta afección, desde métodos menos invasivos hasta cirugías abiertas más complejas. Presentamos un caso de cuerpo extraño impactado en uretra bulbar con el objetivo de analizar métodos diagnósticos empleados y aproximaciones terapéuticas concluyendo en la resolución quirúrgica convencional. Se evaluaron resultados postoperatorios.

Virtual Reality as a distraction therapy during cystoscopy: a clinical trial / A Realidade Virtual como terapia de distração durante cistoscopias: um ensaio clínico

ABSTRACT Objectives: to investigate whether virtual reality (VR) experience is associated with decreased pain sensation among patients who undergo rigid cystoscopy under local anesthesia. Methods: we performed a prospective, randomized, controlled study of 159 patients who were aleatorily enrolled into two groups: VR and control. VR experience intervention consisted of using a headset with a smartphone adapted to a virtual reality glasses where an app-video was played during the procedure. Main outcomes analyzed were pain, discomfort, heart rate variability, difficulty and duration of the cystoscopy. Statistical analyses were performed using a Student's t test, Mann-Whitney test and Chi-square test. A P<0.05 was considered to be statistically significant. Results: among 159 patients studied (VR group=80 patients; control group=79 patients), the mean age was 63,6 years and 107 (67,3%) were male. There was no statistically significant difference in baseline characteristics between the 2 groups. VR was significantly associated to decreased heart rate variability (6,29 vs 11,09 bpm, P<0,001) and lower duration of the procedure (5,33 vs 8,65 min, P<0,001). Also, when cystoscopies due to double-J extraction were excluded, VR experience was associated with reduced pain on the visual analog score of pain (3,26 vs 4,33 cm, P=0,023). Conclusions: the use of VR as a distraction therapy while performing outpatient cystoscopies is safe, has no side effects, is associated with less pain and discomfort, and reduces length of procedure.

RESUMO Objetivos: investigar se a experiência de realidade virtual (RV) está associada à diminuição da dor em pacientes submetidos à cistoscopia rígida sob anestesia local. Métodos: foi realizado um estudo prospectivo, randomizado e controlado de 159 pacientes que foram alocados aleatoriamente em dois grupos: RV e controle. A intervenção da experiência de RV consistiu no uso de óculos de realidade virtual com smartphone adaptado e fones de ouvido, onde um vídeo foi reproduzido durante o procedimento. Os principais desfechos analisados foram dor, desconforto, variabilidade da frequência cardíaca, dificuldade e duração da cistoscopia. As análises estatísticas foram realizadas com o teste t de Student, o teste de Mann-Whitney e o teste do qui-quadrado. Um P<0,05 foi considerado como estatisticamente significativo. Resultados: entre os 159 pacientes estudados (grupo RV=80; grupo controle=79), a média de idade foi 63,6 anos e 107 (67,3%) eram do sexo masculino. Não houve diferença estatisticamente significativa nas características basais entre os grupos. A RV foi significativamente associada à menor variabilidade da frequência cardíaca (6,29 vs 11,09 bpm, P<0,001) e menor duração do procedimento (5,33 vs 8,65 min, P<0,001). Além disso, quando cistoscopias devido à extração de duplo J foram excluídas, a RV foi associada à redução da dor na escala visual analógica (3,26 vs 4,33cm, P=0,023). Conclusões: o uso da RV como terapia de distração durante a realização de cistoscopias ambulatoriais é seguro, não tem efeitos colaterais, está associado a menos dor e desconforto e reduz a duração do procedimento.

A prospective multicenter randomized non-inferiority clinical trial study of a domestic disposable digital flexible cystoscope versus a reusable Olympus digital flexible cystoscope / 中华泌尿外科杂志

Objective:To investigate the availability and safety of a domestic disposable digital flexible cystoscope compared with a reusable Olympus digital flexible cystoscope in cystoscopy and removal of double J stent.Methods:From August 2018 to March 2019, patients were enrolled in this prospective, open, multicenter, randomized, parallel positive controlled clinical trial study, which were from department of Urology in Renmin Hospital of Wuhan University, the First Affiliated Hospital of Xiamen University and the First Affiliated Hospital of Guangzhou Medical University. The experimental group and control group were assigned into a 1∶1 ratio by random table method. Inclusion criteria included age≥18 years and have indications for cystoscopy or removal of double J stent. Exclusion criteria included patients having acute genitourinary tract infection, having tuberculous bladder contracture, bladder capacity less than 50ml, having urethrostenosis, female menstrual period, pregnancy and lactation, having difficulty for lithotomy position, having serious cardio-cerebrovascular disease and liver or kidney dysfunction. A domestic disposable digital flexible cystoscope was adopted in the experimental group, whereas a reusable Olympus digital flexible cystoscope was used in the control group. Acceptability of image was defined as primary availability indicator, while success rate of working and performance score were defined as secondary availability indicators and mean operating time was calculated for cystoscopy only and cystoscopy plus removal of double J stent respectively, yet rate of adverse event as well as rate of equipment defects were sorted as safety indicators.Results:A total of 188 cases which were listed in per protocol set completed the clinical trial study successfully. There were 95 cases in the experimental group and 93 cases in the control group. Acceptability of image was 93.68%(89/95) and 96.77%(90/93) respectively in two groups( P=0.52). Success rate of working was 100.00%(95/95) and 98.92%(92/93) respectively in two groups ( P=0.49). Performance score was 14.41±0.93 and 14.56±0.84 respectively in two groups ( P=0.23). Mean operating time (MOT) only for cystoscopy was (15.3±2.6) min and (15.4±3.3)min respectively in two groups ( P=0.93), while MOT for cystoscopy plus removal of double J stent was (21.0±3.2) min and (21.7±3.9) min respectively in two groups ( P=0.69). Rate of adverse event was 8.42%(8/95) and 9.68%(9/93) respectively in two groups( P=0.76). There was no equipment defects in both groups. Conclusions:There is no statistical difference in acceptability of image, success rate of working, performance score, mean operating time for cystoscopy or removal of double J stent, rate of adverse events and rate of equipment defects. A domestic disposable digital flexible cystoscope has shown non-inferiority in the availability and safety compared with a reusable Olympus digital flexible cystoscope.

Long term outcomes of one-stage augmentation anterior urethroplasty: a systematic review and meta-analysis

ABSTRACT Objective: The objective is to summarize and characterize the long-term success of anterior augmentation urethroplasty in published series. The current literature on AU consists largely of retrospective series reporting intermediate follow-up and incompletely characterize the long term outcomes of AU. Materials and Methods: A systematic literature review was performed consistent with PRISMA guidelines to characterize long-term outcomes of AU with a minimum upper limit follow-up of 100 months. Penile/preputial skin flaps and graft and oral mucosal graft urethroplasties were included. The primary outcome was stricture-free survival for one-stage AU. Secondary analysis evaluated differences in outcomes based on two failure definitions: the need for intervention versus presence of recurrent stricture on cystoscopy or urethrography. Hazard rates were induced from the reported failure rates of one-stage AU and fixed and random effect models were fitted to the data. Additional subset analysis, removing potential confounders (lichen sclerosus, hypospadias and penile skin graft), was performed. Results: Ten studies met inclusion criteria, and two studies reported separate outcomes for grafts and flaps, and thus were included separately in the analysis. The mean hazard rate across all studies was 0.0044, the corresponding survival rates at 1 year 0.948, 5 years 0.766, 10 years 0.587, and 15 years 0.45. Subset analysis of the 4 select and homogeneous studies noted 1, 5, 10, and 15 years survival rates of 0.97, 0.96, 0.74, and 0.63, respectively. Conclusions: The long-term success rates of augmentation urethroplasty are appear to be worse than previously appreciated and patients should be counseled accordingly.

Application of laparoscopy combined with cystoscopy for the treatment of elderly patients with intraperitoneal bladder rupture / 中华老年医学杂志

Objective:To examine the overall benefits of laparoscopy combined with cystoscopy for the treatment of elderly patients with intraperitoneal bladder rupture, in order to provide recommendations for establishing the optimal treatment regimen for elderly patients with intraperitoneal bladder rupture.Methods:A retrospective analysis was conducted, with clinical data of 31 elderly patients with intraperitoneal bladder rupture(Group A)who received laparoscopic repair at our hospital between July 2017 and March 2020.Group B included 32 elderly patients with intraperitoneal bladder rupture who received repair with laparoscopy combined with cystoscopy during the same period at our hospital.Complete medical records, treatment data and examination data of all patients were available for analysis.Results from perioperative indexes, including activities of daily living(ADL)scores before the procedure and after the follow-up and postoperative complications, were compared between the two groups.Results:Compared with Group A, Group B had a shorter total operation time(106.5±10.2)min vs.(123.3±10.4)min and a shorter hospitalization time(6.2±1.4)d vs.(8.7±1.6)d, with statistically significant differences( t=6.444 and 6.583, P<0.001). The amount of bleeding[46.4(46.4~47.5)]ml vs.[45.7(41.3~47.5)ml, U=1.905, P=0.057], time to first passage of flatus[(2.4±1.1)h vs.(2.7±1.1)h, t=0.874, P=0.386]and time to drainage tube removal[(4.2±0.8)d vs.(4.3±0.8)d, t=0.619, P=0.539]showed no statistically significant differences between the two groups.Group B had a preoperative ADL score of 52.3(51.9, 53.3)and a post-follow-up score of 75.9(75.3, 76.4), while Group A had a pre-operative score of 52.2(51.2, 53.2)and a post-follow-up score of 65.6(64.6, 68.8). At the end of the follow-up, ADL scores of both groups were higher than those before the procedure(Group B: Z=6.832, Group A: Z=6.769, P<0.01), but ADL scores in Group B were higher than in Group A, with statistical significance( Z=6.653, P<0.001); The two groups had no statistical difference in total incidence of complications(12.50% vs.16.12%, χ2=0.003, P=0.959). Conclusions:Compared with laparoscopy alone, laparoscopy combined with cystoscopy can shorten the operation time and promote postoperative rehabilitation for the treatment of elderly patients with intraperitoneal bladder rupture and improve activities of daily living of patients, without increasing the risk of complications, indicating good safety.

Placenta percreta: a rare presentation of obstetric emergency in second trimester

Incidence of adherent placenta is on the rise nowadays due to various reasons. Placenta percreta is seen in 5-7% of cases with adherent placenta, patients with morbidly adherent placenta are at increased risk for major obstetric hemorrhage, usually in the third trimester. Here we present an unusual case of placenta percreta presenting with obstetric emergency after trauma to abdomen in the second trimester. Emergency exploratory laparotomy was done for abruptio placentae with scar dehiscence at 20 weeks period of gestation. Consent for obstetric hysterectomy, if needed, was also taken. Intraoperatively, the placenta was found to be adherent to posterior wall of bladder. Emergency obstetric hysterectomy with bilateral internal iliac ligation with cystoscopy with detrusorrhaphy was done. Patient had an uneventful recovery. Multidisciplinary management with obstetricians, urologists and intensivist is presented hereed.

Feasibility of minimally invasive management in patients with forgotten double J stent: a single centre experience

Background: aim of the study was to present the experience in managing forgotten/encrusted Double J (DJ) ureteral stents and to review the literature on the subject.Methods: Author retrospectively studied patients presenting to the Outpatient Department from January 2016 to January 2019 with forgotten DJ stent(s) (six or more than six months after the insertion). Data was collected for age, gender, indication for DJ stenting, clinical features at presentation, radiological imaging and surgical procedure performed to extract the DJ stents. The post-operative stay, complications of the procedures and morbidity was also studied.Results: During the study period, a total 32 patients reported to the department with history of forgotten DJ stents. Most common age group involved was 41-60 years. Most common presenting symptoms were lower urinary tract symptoms (LUTS) or dysuria.  Duration of stent in-situ ranged from 6 month to 15 years. Most common sites of encrustations along the forgotten DJ stent were ureter and kidney followed by urinary blabber. Fluoroscopic guided DJ stent removal was done in 8 patients. A combination of Cystolithotripsy, URSL and PCNL was needed to clear the stone and extract the DJ stent in remaining patients.Conclusions: Forgotten/encrusted DJ stent may lead to complications ranging from urinary tract infections to loss of renal function. They can be safely and successfully removed, and the renal function can be preserved. Endo-urological management of forgotten encrusted stents is highly successful and often avoids the need for open surgical techniques.

Obstructive uropathy complicating eosinophilic cystitis

@#Eosinophilic cystitis is a rare clinicopathologic condition characterized by predominance of eosinophils throughout the bladder wall. The exact disease mechanism is still being debated. However, it is highly associated with atopy and other immunologic conditions. Reported here is a case of eosinophilic cystitis that presented with irritative voiding symptoms with right-sided flank pain, peripheral eosinophilia, and unilateral obstructive uropathy on imaging. Diagnosis was confirmed and documented with cystoscopy and bladder biopsy. Obstructive uropathy was managed with urinary diversion using double J stent. Immunologic signs and symptoms were treated with corticosteroid and antihistamine. Additionally, irritative voiding complaint was managed with antimuscarinic drug. Patient’s condition is now on remission with normal eosinophil count and creatinine levels, and normal urinalysis. Resolution of obstructive uropathy and bladder pathology were noted on follow up imaging and cystoscopy, respectively.

Fistulectomía vaginal exitosa en un caso de fístula vesicovaginal obstétrica por embolización de arterias uterinas / Successful vaginal fistulectomy in a case of obstetric vesicovaginal fistula due to uterine artery embolization

Resumen ANTECEDENTES: Las fístulas genitourinarias obstétricas se forman como consecuencia de una complicación de la embolización de las arterias uterinas debida a necrosis del útero o de la vejiga. El tratamiento quirúrgico vaginal es una opción menos invasiva, con tasas de éxito que alcanzan 84.12%. CASO CLÍNICO: Paciente de 40 años, con 35.7 semanas de embarazo y acretismo placentario, tratado con embolización de las arterias uterinas e histerectomía obstétrica posterior a la cesárea. A las 3 semanas tuvo pérdida vaginal de orina. En la exploración física, y con apoyo de la prueba de colorantes, cistoscopia y cistografía retrógrada se diagnosticó fístula vesicovaginal obstétrica. Posterior a la disminución del proceso inflamatorio se efectuó la fistulectomía vaginal, con modificación de la técnica de Latzko. La evolución posoperatoria fue satisfactoria, sin recurrencia de la fístula durante el seguimiento en la consulta externa. CONCLUSIÓN: Éste, es el quinto caso de fístula por necrosis vesical postembolización reportado en la bibliografía. La favorable atención del caso permitió concluir que la fistulectomía vaginal es una alternativa viable y segura de tratamiento quirúrgico de este tipo de fístulas obstétricas.

Abstract BACKGROUND: Obstetric genitourinary fistulas can cause as a complication of uterine artery embolization due to necrosis of the uterus and/or bladder. Vaginal surgical treatment is a less invasive option with success rates of up to 84.12%. CLINICAL CASE: A 40-year-old woman who came with a pregnancy of 35 5/7 weeks and placenta accreta, which was managed with uterine arteries embolization and obstetric hysterectomy after caesarean section. At 3 weeks she had vaginal urine loss; by physical examination and with support of dye test, cystoscopy and retrograde cystography, obstetric vesicovaginal fistula was diagnosed. After the improvement of the inflammatory process, vaginal fistulectomy was performed with modification of the Latzko technique. Its postoperative evolution was satisfactory and without recurrence of the fistula during the follow-up in the outpatient clinic. CONCLUSION: This is the fifth case of post-embolization bladder necrosis reported in the literature. The favorable resolution of this case allows us to conclude that vaginal fistulectomy is a viable and safe alternative in the surgical treatment of this type of obstetric fistulas.

Dehiscencia de cistorrafia en pacientes con embolización de arterias uterinas por acretismo placentario: reporte de dos casos / Cistorraphy dehiscence in patients with uterine arteries embolization due to placentary acretism: report of two cases

Resumen: ANTECEDENTES: La incidencia de percretismo varía de 5-7% y de ésta, 78% corresponde a complicaciones relacionadas con la cirugía. Hasta la fecha existen pocos casos reportados de dehiscencia de cistorrafia posterior a la embolización de arterias uterinas. CASOS CLÍNICOS: Caso 1. Paciente de 34 años, con embarazo de 36 semanas y diagnóstico de acretismo placentario. El tratamiento consistió en embolización de arterias uterinas e histerectomía subtotal, con lesión vesical reparada sin complicaciones. Dos semanas después del alta hospitalaria acudió a consulta por pérdida de orina y fiebre (pielonefritis aguda); se estableció el diagnóstico de dehiscencia de cistorrafia por tomografía y cistografía retrógrada. Se realizó cateterización ureteral bilateral, laparotomía exploradora con traquelectomía, resección de los bordes necróticos vesicales y cistorrafia. Caso 2. Paciente de 30 años, con embarazo de 37 semanas y acretismo placentario; se aplicó tratamiento similar al caso 1, del que devino una lesión vesical reparada sin complicaciones. Durante la hospitalización permaneció en vigilancia por hemorragia obstétrica e infección urinaria con mala evolución; dos semanas después tuvo pérdida de orina, por lo que se efectuaron: cistoscopia, tomografía y cistografía retrógrada. Se estableció el diagnóstico de dehiscencia de cistorrafia. Durante la cirugía se localizó el defecto por cistoscopia e histeroscopia, se cateterizaron los uréteres de ambos lados; posteriormente, mediante acceso laparoscópico, se resecaron los bordes vesicales necróticos y se complementó con cistorrafia. Ambas pacientes evolucionaron sin complicaciones. CONCLUSIÓN: La dehiscencia de cistorrafia en pacientes con embolización de arterias uterinas es una complicación excepcional. La sospecha diagnóstica y el tratamiento oportunos, con resección de los bordes necróticos y cistorrafia, se asocian con mayor tasa de éxito.

Abstract: BACKGROUND: The incidence of percretism is 5-7% with 78% of complications associated with surgical management. There are few reported cases of cystorraphy dehiscence after uterine arteries embolization. CLINICAL CASES: Case 1. A 34 years old patient with a pregnancy of 36 5/7 weeks and acretism; she was treated with uterine artery embolization plus subtotal hysterectomy with bladder injury repaired without complications. She was discharged, and in 2 weeks she consulted for vaginal urine loss and fever (acute pyelonephritis); cystorraphy dehiscence was diagnosed with support of tomography and retrograde cystography. Bilateral ureteral catheterization, laparotomy with trachelectomy plus resection of bladder necrotic edges and cystorraphy were performed. Case 2. A 30 years old patient with a pregnancy of 37 5/7 weeks and acretism; equal treatment of acretism was given with bladder injury repaired without complications. She was hospitalized in surveillance for obstetric haemorrhage and urinary infection with torpid evolution; she referred vaginal urine loss at 2 weeks, so cystoscopy, tomography and retrograde cystography were performed which diagnosed cystorraphy dehiscence. In surgery the bladder defect was located by cystoscopy and hysteroscopy and bilateral ureters were catheterized; subsequently, by laparoscopic approach necrotic bladder edges were resected and cystorraphy was performed. Both patients without complications and with successful postoperative evolution. CONCLUSION: Cystorraphy dehiscence in embolized patients is extremely rare; however, it should be considered as a possible complication. Diagnostic suspicion and timely management with resection of necrosis and new cystorraphy, achieve greater success.

Genitourinary involvement in colorectal cancer: pre-operative diagnostic utility of CEA, computed tomography and cystoscopy in predicting surgical involvement

OBJECTIVE@#This study aims to describe the demographics, clinical characteristics of patients, and the sensitivity and specifity of the clinical, laboratory, radiologic, diagnostic parameters in detecting histopathologically-proven urinary tract involvement in primary colorectal cancer patients referred to the urology service in the Philippine General Hospital. @*METHODS@#This was a retrospective, cross-sectional study. The study included patients referred to the Division of Urology from the Division of Colon, Rectal and Anal Surgery January 1, 2018 to December 31, 2018. All patients diagnosed with colorectal malignancy and referred to the Urology service were included in the study, including their cystoscopy, axial tomography, CEA and symptom assessment scores.@*RESULTS@#Fifty-eight patients were included in the study and, 43% were rectal cancers and 33% were sigmoid cancers. Sensitivities and specificities were as follows. Symptoms 40%, 84%, Cystoscopy, 45%, 100%; Axial tomography 75%, 79%. Surgical involvement correlated with histopathologic involvement with a specificity of 52%. CEA did not discriminate between cohorts of positive or negative involvement.@*CONCLUSION@#Cystoscopy, axial tomography and symptom assessment had high positive predictive values. All diagnostics had low negative predictive values when taken in isolation. Surgical assessment correlated with histopathologic findings in half of the population. CEA did not discriminate between those with surgical involvement and those without. A multi-modality assessment strengthens detection of surgical involvement preoperatively.

Clinical study and management of genitourinary tuberculosis

Background: Tuberculosis can affect any organ system of the body, including the genitourinary tract. Genitourinary TB is the most common form of extra pulmonary TB accounting for 27% (14- 41%) worldwide. Aim and objectives: To study distribution of GU TB in relation to age, sex, anatomical site, signs and symptoms and to study various diagnostic modalities, treatment and role of surgery in GU TB. Materials and methods: This study was a cross sectional study done at department of Urology, King George hospital, Visakhapatnam. The study was done over a period of 30 months, which was from September 2014 to February 2017. All the patients reporting to the hospital with proven genitourinary tuberculosis or diagnosed after coming to the hospital were included in the study. Total number of cases was 35. 10 were males and 25 were females. History, physical examination, laboratory and radiological investigations were done on the patients and the primary focus of the disease and organs involved are determined. All the patients received treatment as indicated. Results: Most of the patients (33 out of 35) belonged to low socio-economic status and came from rural settings. Of them 10(28.57%) were males and 25(71.43%) were females. The mean age of patients was 36 years (range 16-60years). 2 patients were <20 years, 11 patients were between 21-30 years, 11 patients were between 31-40 years, 8 patients were between 41-50 years and 3 were above 50 years. In this study, kidney was involved in 19 cases and was the most common organ involved, followed by bladder (14 cases) and ureter(10 cases). Irritative voiding symptoms were the most common symptom seen in 23 cases. Flank pain was noted in 20 cases, sterile pyuria in 22 cases and hematuria in 7 cases. Six(17.14%) out of thirty five patients had renal failure at the time of presentation and diagnosis. Nephrectomy was done in 12 cases. Nephrectomy with augmentation Immadi Chandrasekhar, Pasalapudi Anurag Jose. Clinical study and management of genitourinary tuberculosis. IAIM, 2019; 6(1): 48-57. Page 49 cystoplasty and ureteric reimplantation was done in another 6 cases. Ileal conduit was done in 6 cases. Ureteric reimplantation with psoas hitch was done in 3 cases. Conclusion: Genitourinary tuberculosis is often silent and has nonspecific clinical features. Irritative voiding symptoms are the common presentation. Kidney is the most commonly affected organ in GU TB. GU TB is a disease of young adults, with majority affected in the 3rd and 4th decades. CT scan is replacing IVU as an imaging modality of choice in GU TB. Diagnosis of GU TB can be baffling, compelling a high index of suspicion owing to paucibacillary load in the biological specimens and the difficulty to isolate or grow TB bacilli. Hence a strong clinical suspicion is necessary for correct diagnosis. Anti-tubercular therapy is the mainstay of treatment. Genitourinary tuberculosis results in sequel which may require major organ removing and reconstructive surgeries

Intrauterine contraceptive device embedded in bladder wall with calculus formation removed successfully with open surgery

@#An Intrauterine contraceptive devices (IUCD) is commonly inserted by the primary health care physician. It can migrate into pelvic or abdominal organs. When a pregnancy occurs following an insertion of an IUCD, there should be a high suspicion of uterine perforation or possible migration. A radiograph can be done in the primary health care clinic to search for a missing IUCD. Early referral to the urology service is warranted when a patient presents with recurrent urinary tract infections. Removal of an intravesical IUCD can be managed with cystoscopy, laparoscopy or open surgery. Herein, we report a case of IUCD migration into the bladder. This case will highlight the importance of proper technique, careful insertion and the role of ultrasound.

Spiral thermo-expandable prostatic stent implantation for benign prostatic hyperplasia: Clinical analysis of 26 cases / 中华男科学杂志

Objective@#To investigate the surgical techniques and clinical effect of Memokath transurethral spiral thermo-expandable prostatic stent (STEPS) implantation in the treatment of BPH.@*METHODS@#From January 2017 to January 2018, 26 BPH patients underwent Memokath transurethral STEPS implantation, 9 under the flexible cystoscope and the other 17 under the rigid cystoscope. The patients were aged 62－91 years old, with a prostate volume of 32－78 ml, postvoid residual urine volume (PVR) of (67.3 ± 11.2) ml, maximum urinary flow rate (Qmax) of (6.3 ± 1.8) ml/s, and IPSS score of 26.7 ± 5.7. Eight of the patients had preoperative urinary retention, of whom, 6 received catheterization and 2 had undergone cystostomy for bladder fistula before STEPS implantation.@*RESULTS@#The operations lasted 15－30 minutes and were successfully completed in 24 cases while stent-shedding occurred in the other 2. Twenty-two of the patients achieved spontaneous urination immediately after surgery and 2 experienced bladder clot embolism. At 3 month after surgery, 24 of the patients showed significant improvement in PVR (［21.4 ± 7.7］ ml), Qmax (［18.3 ± 4.7］ ml/s) and IPSS (8.3 ± 2.1), and 13 exhibited no statistically significant difference from the baseline in the IIEF-5 score (14.1 ± 1.1 vs 14.3 ± 1.0, P > 0.05). At 12 months, all the patients were found with markedly improved urination but no adverse events except recurrent urinary tract infection in 2 cases.@*CONCLUSIONS@#Memokath STEPS implantation, with its advantages of simple operation, high safety, definite effectiveness, non-influence on sexual function, is a new effective surgical option for the treatment of BPH.

Application of oral acetaminophen combined with urethral surface anesthesia in local anesthesia cystoscopy / 国际外科学杂志

Objective To investigate the application efficacy of oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy.Methods From January 2016 to June 2017,180 male patients aged from 60 to 86 years old,whose average age was 71 years old and treated by local anesthesia cystoscopy were collected in this study in the department of Urology of Xuzhou Medical University Affiliated hospital.They were divided into two groups according to the time sequence of visiting doctor.The patients in the research group were treated with oral acetaminophen stapler with compound lidocaine cream and lidocaine injection urethral infusion anesthesia before the examination.The control group was using lidocaine injection urethral infusion anesthesia.To compare the successful rate of operation,operating time and the visual analogue score (VAS) before and after the operation,the patients'limb twist and the tension were observed and recorded.The software of SPSS 16.0 was used for statistical analysis.Results The successful rate of operation in research group and control group was 97.78％ and 91.11％.The VAS score before the operation was (3.2 ± 1.8) and (6.8 ± 2.2).The incidence of complications after treatment was 5.55％ (5/90) and 27.78％ (25/90).The PSS score of 1 h after treatment was (1.1 ± 1.7) and (3.1 ± 1.2).The satisfaction rate was 90.0％ (81/90) and 57.8％(52/90).The differences between the two groups were statistically significant(P ＜ 0.05).However,the opertion time between the two groups was (6.2 ± 1.7) and (6.9 ± 2.1) min.One hour after the opertion,the VAS score was (1.2±0.7) and (1.5±1.1).The score of PSS before the opertionwas (3.4±1.5) and (3.8±1.1).There were no significant differences between the two groups (P ＞ 0.05).Conclusions Taking oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy could obviously reduce urethral pain and the anxiety in the opertion of local anesthesia cystoscopy,which obviously superior to use lidocaine injection urethral infusion anesthesia only.The efficacy and safety were definitely and had got better clinical outcomes.

Comparison of three different endoscopic approaches in the treatment of bladder calculi / 영남의대학술지

BACKGROUND: This study compared the following three endoscopic techniques used to treat bladder stones: transurethral cystoscope used with a pneumatic lithoclast or nephroscope used with a pneumatic lithoclast and nephroscope used with an ultrasonic lithoclast.METHODS: Between January 2013 and May 2016, 107 patients with bladder stones underwent endoscopic treatment. Patients were classified into three groups based on the endoscopic techniques and energy modalities used in each group as: group 1 (transurethral stone removal using a cystoscope with pneumatic lithoclast), group 2 (transurethral stone removal using a nephroscope with pneumatic lithoclast), and group 3 (transurethral stone removal using a nephroscope with ultrasonic lithoclast). Baseline and perioperative data were retrospectively com-pared between three groups.RESULTS: No statistically significant intergroup differences were observed in age, sex ratio, and stone size. A statistically significant intergroup difference was observed in the operation time—group 1, 71.3±46.6 min; group 2, 33.0±13.7 min; and group 3, 24.6±8.0 min. All patients showed complete stone clearance. The number of urethral entries was higher in group 1 than in the other groups. Significant complications did not occur in any patient.CONCLUSION: Nephroscopy scores over cystoscopy for the removal of bladder stones with respect to operation time. Ultrasonic lithoclast is a safe and efficacious modality that scores over a pneumatic lithoclast with respect to the operation time.

Confocal laser endomicroscopy for diagnosing malignant bladder tumour: a pilot study / 中华泌尿外科杂志

Objective To perform an exploratory investigation on confocal laser endomicroscopy (CLE) in the diagnosis of malignant bladder tumour.Methods From June 10 to July 11,2017,6 male bladder cancer patients underwent white light cystoscopy (WLC) + CLE examination,aging 64-86 years (median 72 years).All patients received TURBT on suspected lesions.WLC and CLE imaging results were recorded and validated by pathologic specimens.Results Lesions confirmed by histopathology were 3 low grade non-invasive papillary urothelial carcinomas,1 high grade non-invasive papillary urothelial carcinoma,1 low grade invasive urothelial carcinoma,1 high grade invasive urothelial carcinoma,1 carcinoma in situ (CIS),1 high grade dysplasia,1 cystitis glandularis,1 chronic inflammation,and 1 scar tissue.For CLE images in the normal urothelium,three layers of cells with different presentation were observed,namely,the superficial umbrella cells,the intermediate cells smaller in size and uniformly shaped,and the capillary network in the lamina propria.For non-invasive urothelial carcinoma,tumour cells appeared as papillary lesions growing from fibrovascular cores,with low grade cells appearing monomorphic and more cohesively arranged,and high grade cells relatively pleomorphic,more disorganised and with tortuous blood vessels in the fibrovascular core.For invasive urothelial carcinoma,tumour cells invaded the lamina propria,with uniform appearances,poor cohesion and indistinct cellular borders,and high grade ones were more pleomorphic.CIS and inflammation both appeared as erythematous patch-like flat lesions under WLC and sometimes difficult to differentiate.Under CLE,the former appeared as dysplastic and disorganised cells with indistinct cellular borders,with intact lamina propria,and inflammatory cells were discovered as infiltrative clusters in the lamina propria that were uniformly shaped and loosely connected.Dysplasia appeared somewhat similar compared with CIS under WLC,but with lower cellular irregularity as confirmed with pathology.Cellular appearance and structure in scar tissue was similar to that in the normal urothelium,but superficial umbrella cells were more likely absent,with thinner cell layers,and inflammatory infiltration was sometimes discovered in the lamina propria.Conclusions CLE provides real-time cellular imaging of the urothelium,and shows promising potential for clinical diagnosis,especially in differentiating fiat urothelial lesions.Large prospective studies are required for further validation.

The diagnostic value of narrow-band imaging for fiat bladder lesions / 中华泌尿外科杂志

Objective To investigate the diagnostic value of narrow-band imaging for flat bladder lesions.Methods Forty-nine patients with flat bladder lesions diagnosed by white light cystoscopy + narrow-band imaging followed by transurethral resection were included.The diagnostic value of narrow-band imaging was evaluated based on postoperative pathological results.Results A total of 59 flat lesions were identified,in which 8 were normal urothelium,3 were chronic inflammation,1 was papillary urothelial neoplasm of low malignant potential,1 were mild dysplasia,1 was moderate dysplasia,1 were severe dysplasia,3 were carcinoma in situ,16 were low-grade papillary urothelial carcinoma,16 were high-grade papillary urothelial carcinoma,and 8 were invasive papillary urothelial carcinoma.For narrow-band imaging,the sensitivity was 86.7 ％ (39/45),specificity was 57.1％ (8/14),diagnostic accuracy was 79.7 ％ (47/ 59),false-positive rate was 42.9％ (6/14),positive predictive value was 86.7％ (39/45),negative predictive value was 57.1％ (8/14),area under ROC curve was 0.719.Among these lesions,the sensitivity and specificity for postoperative recurrent lesions were 100％ (3/3) and 40％ (2/5),respectively,and those for erythematous patch-like lesions were 90％ (9/10) and 100％ (4/4),respectively.Conclusion Narrow-band imaging can improve the detection rate for flat bladder tumor lesions,and reduce the risk for missed diagnosis under white light cystoscopy,especially for otherwise indistinguishable erythematous patch-like lesions.
