Introduction The treatment of intestinal perforation caused by the SBC enters the small intestine in elderly patients is a challenge for urologists. The report is to share our experience of conservative treatment after a 90-year-old male with the suprapubic bladder catheter enters the small intestine. Presentation of case Because of the device was obstructed, a 90-year-old male went to our hospital with his family and requested to replace the SBC. When the fistula tube was replaced, it entered the intestine through the intestinal injury site instead of entering the bladder. During the hospitalization, the patient was given supportive treatments and the SBC was dynamically monitored daily and it was intermittently withdrawn out during this period. After the drainage volume was less than 10 mL for three consecutive days and the intestinal fistula was healing gradually, the catheter was taken out. Discussion According to our experience, the common complications in the process include failure to pull out the SBC, abnormal position of the SBC, and poor drainage of the SBC. However, the drainage tube placing into the small intestine through the original hole of the suprapubic bladder fistula during the replacement process is quite rare. When elderly patients have traumatic small bowel perforation, the diagnosis and treatment of intestinal perforation in elderly patients was particularly important. Conclusion The conservative treatment of intestinal perforation is suitable for elderly patients who are unsuitable or unwilling to undergo a surgical operation. Of course, it should be in accordance with the patient's condition to make the right choice of treatment.

Introduction. Entero-bladder fistula (fistula entero-vesicalis) is a pathological connection between the lumen of the gastrointestinal tract and the bladder. Entero-bladder fistulas are not a common condition. The main reason for the formation of entero- bladder fistulas are intestinal diseases occurring within the intestinal loop adjacent to the bladder resulting in the formation of an abnormal channel, the connection between the above structures Aim. The aim is to present the causes of the fistulas can be divided into congenital and acquired (intestinal infection, cancer, Crohn’s disease, resulting from trauma and iatrogenic). Clinical manifestations of the biliary-bullous fistulae may be from the digestive or urinary tract. The most characteristic ailments are pneumaturia, fecuria, urge to urinate, frequent urination, lower abdominal pain, hematuria, urinary tract infection. Description of the case. The article discusses the case of a patient with Leśniowski-Crohn disease complicated with a bladder- fistula. The treatment of entero-bladder fistulas is primarily surgical, it consists in resection of the fistula together with resection of the affected intestine and bladder wall fragment. Conclusion. The test confirming the presence of an entero-bladder fistula is a test with oral administration of poppies, although it happens that the test result may be negative, especially in the case of a bladder-follicular fistula. Among the tests useful in the diagnosis of entero-bladder fistula include abdominal ultrasound, computed tomography, magnetic resonance imaging, endoscopic tests (colonoscopy or cystoscopy).

Introduction Refractory fistulas of the bladder are not rare, but they can rarely be closed naturally. Bladder fistulas can be treated in various ways. We report the case of an old woman who had a refractory fistula of the bladder that was able to be repaired with transurethral cystoscopic injection of N-butyl-2-cyanoacrylate. Case presentation For decades after being treated for cervical cancer in 1970s, the woman frequently suffered from fevers. A computed tomography scan showed pelvic abscess at the left side of her bladder, and cystography showed urine leakage at the wall. Thus, we diagnosed her with a pelvic abscess due to a bladder fistula after radiation. Then, we treated her with drainage, antibiotic agents, and N-butyl-2-cyanoacrylate. After that, she no longer had fevers, and cystography showed no leakage of urine. Conclusion This result indicates transurethral cystoscopic injection of N-butyl-2-cyanoacrylate may treat bladder fistulas safely, minimally invasively, and quickly.

Background. Radical cystectomy uses laparoscopic and robotic approaches along with the open ones.Objective: to study immediate results of robot-assisted radical cystectomy with intracorporeal orthotopic cystoplasty.Materials and methods. Robot-assisted radical cystectomy with intracorporeal orthotopic cystoplasty was performed in 15 patients (13 male, 2 female), aged 64–76 years. Fourteen patients had bladder cancer, 1 female – a postradiation bladder fistula and microcystis. T2 stage was detected in 8 (57.1 %) patients, T3 – in 6 (42.9 %). After the operation we evaluated operation time, blood loss volume, hospital stay, functional and oncological results.Results. Average operation time was 380 (320–560) minutes, blood loss volume – 80–200 ml, blood transfusion was not performed. Early complications (up to 30 days) were observed in 7 patients (46.7 %), late ones (90‑days) – in 6 (40.0 %). There were no cases of intestinal obstruction. Patients with ureteral-intestinal (n = 2) and reservoir-urethral (n = 1) anastomosis failure underwent percutaneous renal drainage. One patient died of acute myocardial infarction. Daytime continence was 80.0 %, nocturnal – 53.3 %. One patient died of disease progression within 7.6 observation months.Conclusion. Robot-assisted radical cystectomy with intracorporeal urine diversion is a modern and minimally invasive method for patients with muscle-invasive bladder cancer. More experience in this field will allow to reduce surgery time and number of complications.

Complex lower urinary tract injury resulting from hysterectomy is a rare but highly morbid complication. Although intraoperative recognition reduces the risk of serious sequelae, observational studies have shown that most complex lower urinary tract injuries are recognized in the postoperative period. To date, limited research exists describing the timing of diagnosis of complex lower urinary tract injury or risk factors associated with complex lower urinary tract injury diagnosed in the postoperative period.This analysis aimed to describe the time to diagnosis of complex lower urinary tract injury among women undergoing benign hysterectomy. We also aimed to identify the intraoperative risk factors for differences in type and timing of complex lower urinary tract injury in the 30-day postoperative period using a large prospective national surgical database.This was a retrospective analysis using the National Surgical Quality Improvement Program hysterectomy data set from 2014 to 2018. All benign hysterectomies were included. Sociodemographic factors, health status, surgeon type, and other operative characteristics were extracted. A complex lower urinary tract injury was defined as at least 1 ureteral obstruction, ureteral fistula, or bladder fistula diagnosed within the first 30 days following surgery. Bivariate and multivariate logistic regression and cox proportional hazards assessed differences in odds of and time until diagnosis of complex lower urinary tract injury. Proportional hazard assumptions were evaluated with martingale residuals and supremum tests. Significance thresholds were 0.05 for all analyses.In this study, 100,823 women met the inclusion criteria. Median time to diagnosis of complex lower urinary tract injury was 10 days (interquartile range, 3-19) and varied significantly based on type of injury (P.01) with ureteral obstruction (6; interquartile range, 2-16) recognized earlier than ureteral fistula (12; interquartile range, 7-21) and bladder fistula (14; interquartile range, 4-23). In addition, 8.65% of complex lower urinary tract injury were diagnosed on the day of surgery. Total laparoscopic hysterectomy had the lowest rate of complex lower urinary tract injury in unadjusted and adjusted analysis, with abdominal hysterectomy (adjusted odds ratio, 2.02; 95% confidence interval, 1.21-3.36) and vaginal hysterectomy (adjusted odds ratio, 2.05; 95% confidence interval, 1.16-3.62) having greater odds of ureteral obstruction, whereas laparoscopic assisted vaginal hysterectomy had the greatest odds of fistula (adjusted odds ratio, 2.10; 95% confidence interval, 1.26-3.48). Concomitant apical suspension was associated with a 6-day reduction in median time to diagnosis (P=.01), and surgery with a gynecologic oncologist was associated with a 9.5-day increase in median time to diagnosis (P=.01). Cox proportional hazards analysis confirmed these findings when controlling for confounders.Greater than 91% of complex lower urinary tract injury diagnoses in the National Surgical Quality Improvement Program hysterectomy database were diagnosed after the day of surgery. Route of hysterectomy, concomitant apical suspension, and primary surgeon specialty are associated with differences in both type of injury and time until diagnosis. These intraoperative risk factors should be considered when assessing for complex lower urinary tract injury in the 30-day postoperative period.

Purpose: To identify patient- and treatment-related risk factors for fistula, bleeding, cystitis, pain and difficulty in voiding in locally advanced cervical cancer patients treated with radio(chemo)therapy and image-guided adaptive brachytherapy (IGABT). Material and methods: Morbidity within the EMBRACE-I study was prospectively reported for physician-assessed (CTCAE) fistula, bleeding and cystitis and patient-reported (EORTC) pain and difficulty in voiding. Analysis of risk factors was performed in patients without bladder infiltration. Risk factors were tested with Cox regression for grade (G) ≥ 3 cystitis, for G ≥ 2 fistula, bleeding and cystitis, and for EORTC “very much” and “quite a bit” or worse. Results: Of 1416 patients enrolled, 1153 and 884 patients without bladder infiltration were evaluable for the analysis of CTCAE and EORTC items, respectively. Median follow-up was 48[3–120] months. Crude incidence rates for G ≥ 2 fistula, bleeding and cystitis were 0.7%, 2.7% and 8.8%, respectively, and 16% and 14% for ”quite a bit” or worse pain and difficulty in voiding, respectively. Baseline urinary morbidity and overweight/obesity were significant risk factors for most endpoints. Bladder D2cm3 correlated with G ≥ 2 fistula, bleeding and cystitis, while ICRU bladder point dose correlated with EORTC pain “quite a bit” or worse. An increase from 75 Gy to 80 Gy in bladder D2cm3 resulted in an increase from 8% to 13% for 4-year actuarial estimate of G ≥ 2 cystitis. Conclusion: Clinical and treatment-related risk factors for bladder fistula, bleeding and cystitis were identified within a prospective and multi-institutional setting. A dose–effect was established with bladder D2cm3, reinforcing the importance of continued optimization during individualized IGABT planning.

Summary Background We present the long-term results and complications of the DETOUR® prosthesis, a permanent subcutaneous pyelovesical bypass for the treatment of ureteral obstruction. Patients and methods Between 2006 et 2018, 34 prosthesis were implanted in 28 patients (mean age 65,8 years) with ureteral obstruction of malignant or benign etiologies. The prosthesis, composed to an inner tube of silicone and an outer tube of expanded polytetrafluoroethylene, is placed subcutaneously between the kidney and the bladder. We are performed infrared spectrophotometry and scanning electron microscopy on two removed prostheses to explore the prosthetic encrustation. Results The average follow-up was 25,8 months (Maximum: 64 months). Stent revision was required for early bladder fistula in three patients. The major long-term complications were infection (46%), obstruction (3 patients) and bladder fistula (7 patients). The most frequently infection are non-severe, but two patients died from septic shock after fungic colonization of the prosthesis. The infrared spectrophotometry and scanning electron microscopy analysis showed that the obstruction was favored by urinary infection and an alkaline medium. The functional prosthesis rate at 1,2 and 3 years was 94%, 71% and 62%, respectively. Conclusion The DETOUR® subcutaneous extra-anatomical urinary bypass is an effective and minimally invasive alternative to permanent percutaneous nephrostomy, for both malignant and benign ureteral obstructions in selected patients. Level of evidence 3.

Highlights • Vesicouterine fistula is pathological communication between the bladder and uterus or cervix. • Symptoms of VUF were secondary amenorrhea and cyclic hematuria with history of previous cesarean section (concluded as Youssef’s syndrome). • Surgical approach is contemplated as definitive management of the VUF following caesarean section. • A group of women was able to have normal period after fistula repair., Vesicouterine fistula (VUF) is an abnormal communication between the bladder and uterus, occurring 1–4% of all urogenital fistulas. Diagnosis is still a challenge because symptoms may appear late or fistula may be missed even after repeated examination. A 37-year old woman who has two children born through caesarean section complained of the absence of menstruation for the past three years. At the same time point, she experienced cyclic haematuria and amenorrhea. The diagnosis was made through ultrasonography, cystoscopy and hysteroscopy. She was then managed with laparoscopic bladder fistula repair continued with total laparoscopic hysterectomy. The VUF can present as an undesirable consequence of caesarean section.

Background: Mitomycin C (MMC) extravasation after transurethral resection of bladder tumor (TURBT) is a rare and highly morbid complication. Management of these cases may require a multidisciplinary approach with strategies ranging from conservative management to surgical intervention. Case Presentation: We present a 48-year-old woman who received a TURBT for a 5 mm bladder tumor. Procedure was uneventful and no bladder perforation was noticed. A single dose of instillation of MMC was performed after surgery resulting in extravasation, consequent ipsilateral pudendal neuralgia, and ureterohydronephrosis. Treatment included a second TURBT, Double-J stent placement, and multiple pain management schemes. After 8 months the patient had complete resolution of pain and ureterohydronephrosis. Conclusion: Perioperative chemotherapy is the standard of care in low-risk bladder cancer. Extravasation of MMC, although rare, can produce severe complications, sometimes irreversible. Other treatment options, such as gemcitabine, are less frequently used despite being less irritant and having similar efficacy. Further studies are needed to compare single-dose instillation regimens.

A bladder to lumbar hardware fistula has never been reported. We report the case of a 67 year old male who presented with a bladder to lumbar spinal hardware fistula approximately four years following an L4-S1 anterior lumbar internal fixation. It was identified through the use of CT cystogram. His case was managed first with cystoscopy and interrogation of the fistula with a Glidewire followed by partial cystectomy and removal of some of the offending spinal hardware.

Spontaneous cystic artery-gallbladder fistula is an extremely rare condition described in the medical literature. We have found two articles in the literature describing fistula formation between the cystic artery and gall bladder. In this report, we present a unique case of a cystic artery-gall bladder fistula that resulted in massive gastrointestinal bleeding through cystic artery erosion and was adequately managed with coil embolization.

Objective Laparoscopic surgery for diverticular colovesical fistula (CVF) is technically challenging, and the incidence of conversion to open surgery (COS) is high. This study aimed to review our experience with laparoscopic surgery for diverticular CVF and identify preoperative risk factors for COS. Results This was a single institution, retrospective, observational study of 11 patients (10 males and 1 female) who underwent laparoscopic sigmoid colon resection with fistula resection for diverticular CVF from 2014 to 2019. Preoperative magnetic resonance imaging (MRI) was performed to evaluate the fistula location in the bladder, patency of the rectovesical pouch (i.e., the destination of dissection procedure between sigmoid colon and bladder) and estimate the contact area between the sigmoid colon and bladder. The relationship between preoperative variables and COS incidence was analyzed between completed laparoscopy and COS groups. The overall incidence of postoperative morbidity (Clavien–Dindo classification Grade II or higher) was 36% (4/11). Severe morbidity, reoperation, and mortality were not observed. The incidence of COS was 27% (3/11). Posterior bladder fistulas were significantly associated with COS. CVFs located on the posterior bladder appears to be a risk factor for COS. Identifying risk factors for COS preoperatively could help guide the intraoperative course.

A 50-year-old woman presented with a 5-month history of recurrent urinary tract infections. She had no complaints of any intestinal symptoms. She had been treated previously with oral antibiotics. The episodes became more frequent and she started with pain in the lower abdomen and fetid urine. Complete study lead to diagnosis of adenocarcinoma of the appendix with bladder fistula. The lesion was removed by laparoscopic right hemicolectomy and en bloc partial cystectomy. Pathological examination revealed a mucinous adenocarcinoma that had originated in the appendix and extended into the bladder wall. Six years after the operation, the patient remains asymptomatic with no evidence of recurrent or metastatic disease. Appendiceal carcinoma extending to the bladder is extremely rare and approximately 40 cases have been described. Management of recurrent urinary tract infections should not limit to empiric antibiotic therapy before the exclusion of possible organic causes. Appendiceal carcinoma may invade the bladder without intestinal symptoms but with urinary symptoms only, because of its anatomical position. The recommended treatment for non-carcinoid appendiceal tumours is right hemicolectomy and for T4 tumours en bloc resection of the involved structures. Further study is needed to determine adjuvant therapy. A literature review was made.

Background Hysterectomy for placenta accreta spectrum may be associated with urologic morbidity, including intentional or unintentional cystostomy, ureteral injury, and bladder fistula. Although previous retrospective studies have shown an association between placenta accreta spectrum and urologic morbidities, there is still a paucity of literature addressing these urologic complications. Objective We sought to report a systematic description of such morbidity and associated factors. Study Design This was a retrospective study of all histology-proven placenta accreta spectrum deliveries in an academic center between 2011 and 2020. Urologic morbidity was defined as the presence of at least one of the following: cystotomy, ureteral injury, or bladder fistula. Variables were reported as median (interquartile range) or number (percentage). Analyses were made using appropriate parametric and nonparametric tests. Multinomial regression analysis was performed to assess the association of adverse urologic events with the depth of placental invasion. Results In this study, 58 of 292 patients (19.9%) experienced urologic morbidity. Patients with urologic morbidity had a higher rate of placenta percreta (compared with placenta accreta and placenta increta) than those without such injuries. Preoperative ureteral stents were placed in 54 patients (93.1%) with and 146 patients (62.4%) without urologic injury (P=.003). After adjusting for confounding variables, multinomial regression analysis revealed that the odds of having adverse urologic events was 6.5 times higher in patients with placenta percreta than in patients with placenta accreta. Conclusion Greater depth of invasion in placenta accreta spectrum was associated with more frequent and severe adverse urologic events. Whether stent placement confers any protective benefit requires further investigation.

Introduction: Small bowel neoplasms are rare entities, with only 3.2% of gastrointestinal tumors localized in this segment. Adenocarcinoma is the second most common histologic type among small bowel neoplasms. The disease's symptoms are non-specific, with abdominal pain being the most common. Among the complications, fistulas are a far rare condition. Case report: We present the case of an 86-year-old woman, hypertensive, diabetic, and former smoker, with lower abdominal pain, hematuria, fecaluria and fever associated with weight loss. Upon physical examination presented pale mucous membranes. Magnetic resonance imaging of the abdomen showed parietal thickening in the distal ileum segment with an anterior wall bladder fistula. Absence of metastases.Subjected to transurethral endoscopic biopsy of the bladder lesion, which anatomopathological study was compatible with invasive mucinous adenocarcinoma. An enterectomy was performed with primary enteroanastomosis, associated with partial cystectomy by videolaparoscopy. Anatomopathological study of the surgical specimens concluded mucinous adenocarcinoma with signet ring cells located in the small bowel and bladder. Immunohistochemical exam has identified findings compatible with mucinous adenocarcinoma of origin in the small bowel. The patient evolved well, being discharged, and returned to postoperative follow-up without signs of relapse of the disease. Conclusion: The relative inaccessibility of the small bowel and the malignant neoplasms’ non-specific symptoms make an early diagnosis difficult. Discovery of the disease, often only at an advanced stage, results in complications and less effective therapy. The laparoscopic approach might be advantageous and effective in the treatment of advanced small bowel cancer with invasion of adjacent structures. Resumo: Introdução: As neoplasias do intestino delgado são entidades raras com apenas 3,2% dos tumores gastrointestinais localizando-se neste segmento. O adenocarcinoma é o segundo tipo histológico mais comum entre as neoplasias do intestino delgado. Os sintomas da doença são inespecíficos, sendo a dor abdominal o mais comum, dificultando o diagnóstico precoce. Dentre as complicações, as fistulas são de ocorrência ainda mais rara. Relato de caso: Mulher de 86 anos, hipertensa, diabética e ex-tabagista. Quadro de dor em abdome inferior, hematúria, fecalúria, febre eventual e perda ponderal. Ao exame físico pele e mucosas hipocoradas. Ressonância Magnética de abdome evidenciou espessamento parietal em segmento do íleo distal com fístula para a parede vesical anterior. Ausência de metástases. Submetida à biopsia endoscópica transuretral da lesão vesical, cujo estudo anatomopatológico evidenciou adenocarcinoma mucinoso invasivo. Realizada enterectomia com enteroanastomose primária, associada à cistectomia parcial por videolaparoscopia. Estudo anatomopatológico das peças cirúrgicas concluiu adenocarcinoma mucinoso com células em anel de sinete localizado em intestino delgado e bexiga. A Imunohistoquímica identificou achados compatíveis com adenocarcinoma mucinoso de origem em intestino delgado. A paciente evoluiu bem no pós-operatório, recebendo alta e retornando para seguimento pós-operatório sem sinais de recidiva da doença. Conclusão: A relativa inacessibilidade do intestino delgado e os sintomas inespecíficos das neoplasias malignas deste sítio dificulta o diagnóstico precoce. O reconhecimento da doença, muitas vezes somente em estágio avançado, resulta em complicações e sequelas com terapêutica menos eficaz. A abordagem laparoscópica pode ser vantajosa no tratamento do câncer avançado do intestino delgado com invasão de estruturas adjacentes.

Abdominal hydatidosis resulting in an internal hydatid bladder fistula postoperatively is quite rare and might have serious consequences without timely treatment. A 74-year-old Tibetan woman presented with abdominal distension and was diagnosed with hydatid disease. Cyst contents were removed, and the pericyst was partially resected without contraindication. Furthermore, no internal urinary fistula was found before or during the operation, and the presence of an internal fistula was indicated by methylene blue retrograde injection via urinary catheter after the operation. The use of postoperative methylene blue retrograde injection via urinary catheter is recommended to identify internal hydatid bladder fistula formation.

Objective: To investigate the pharmacological effects of Leonuri Herba alkaloids (LHA) on prostate hyperplasia in older rats and the effect mechanism. Methods: Remove bilateral testes from BPH model rats, and conduct subcutaneous injection of testosterone and estradiol. At the same time, feed corresponding drugs to the rats by gastric perfusion for 30d. In the first 27d, conduct bladder fistula surgery. Three days after feeding, carry out the detection of the urine flow dynamics. Eyeball blood taking, determination of serum E2 levels, and quickly remove the prostate, thymus gland, spleen, kidney, lung, and bladder. 1/3 prostate homogenate, determine the level of PACP, T, DHT. 1/3 prostate was determined by mRNA expression in bFGF. The remaining 1/3 prostate was observed by light microscopy. Results: LHA could significantly decrease the animal prostate index, level of DHT, T, PACP, and elevate levels of E2 in the serum. It could also significantly reduce the maximum voiding pressure, intercontraction interval, and bladder resting pressure. Conclusion: LHA has good therapeutic effect on prostatic hyperplasia model rats induced by male and female hormone.

Aim Patients undergoing resectional surgery for enterovesical fistulas generally have an indwelling urinary catheter postoperatively to prevent a recurrent fistula. The aim of this study was to assess the role of a cystogram as part of the postoperative follow-up of such surgery, when it should be performed and for how long the bladder should be drained after surgery. Method A retrospective single-centre study of all patients undergoing ileocaecal or sigmoid resection for surgery for enterovesical fistula with the primary end-point of recurrent urinary fistula. Results Between 1994 and 2015, 46 patients (23 male; mean age 55.4 ± 18.3 years) underwent surgery [23 (50%) for diverticular disease, 16 (34.8%) for Crohn's disease, five (10.9%) for malignancy and two (4.3%) for previous radiotherapy]. Closure of the bladder fistula was by simple suture in 21 (46%) patients and with an omental pedicle in 16 (36%). Overall median duration of urinary drainage was 10.5 [interquartile range (IQR): 7.3-14.0] days. A postoperative cystogram was performed in 26 (57%) patients after a median of 10.0 (IQR: 8.0-13.0) days. This demonstrated persistent leakage in three patients, of whom two had undergone surgical closure of the bladder. This group required prolonged drainage (7, 19 and 40 days). One patient who had undergone surgery following radiotherapy for urothelial cancer developed a recurrent malignant fistula at 9 months, even though the postoperative cystogram had been negative. Conclusion This study suggests that a routine postoperative cystogram after surgery for enterovesical fistula may not be necessary for all patients if the bladder is drained for 1-2 weeks after bowel resection.

Bladder fistulas involve an abnormal connection between bladder and either vagina or intestine. In this review chapter, we cover the etiology, clinical presentation, and various surgical approaches to repairing vesicovaginal and enterovesical fistulas. The long-term sequela after surgical repair includes recurrent incontinence, lower urinary tract symptoms, infection, and vaginal stenosis. Strategies to approach fistula repair to minimize these complications are emphasized.

Urinary tract injuries are unfortunate complications of pelvic surgery. With the increasing popularity of minimally invasive surgery, a thorough understanding of electrosurgical instrumentation and their thermal spread is important to reduce patient injuries. The index patient was a 50 year old woman who underwent a supracervical hysterectomy 5 years prior to her presentation with pelvic pain and dysuria. When her symptoms failed to improve despite antibiotic and analgesic therapy, an abdominal CT scan revealed an ovarian cyst and ascites. A subsequent laparoscopy disclosed the presence of a bladder fistula and a diagnosis of urinary ascites was made. The patient then underwent a subsequent bladder fistula repair. Vesicoperitoneal fistulae (VPF) are rare and should be included in the differential diagnosis of the patient with acute onset ascites following gynecologic surgery. This case is the first case report of a VPF occurring 5 years following surgery., Highlights • Vesicoperitoneal fistulas are rare complications following hysterectomy and are easily misdiagnosed. • A normal postoperative cystogram does not exclude the delayed formation of a vesicoperitoneal fistula. • Primary debridement and full-thickness repair following a thermal injury to the bladder is crucial.

Les fistules urinaires sont une complication tardive rare après une radiothérapie pour le cancer de la prostate. Nous décrivons le cas d'un patient âgé de 76 ans, ayant eu quatre ans auparavant une prostatectomie radicale suivie d'une radiothérapie externe pour un cancer de la prostate. Le patient s'est présenté pour une tuméfaction de la cuisse récidivante. L'examen clinique a montré une masse rénitente et indolore au niveau de la partie médiale de la cuisse droite. Le bilan radiologique fait d'une échographie puis d'un scanner a objectivé une grosse collection liquidienne homogène de la face interne de la cuisse exerçant un léger effet de masse sur les vaisseaux fémoraux. Un drainage chirurgical a été réalisé ramenant 900ml de liquide louche dont l'examen bactériologique était négatif. Les suites post opératoires ont été marquées par une diminution brutale de la diurèse, par contre le drain a continué à ramener régulièrement des quantités importantes de liquide clair. Devant ce tableau, nous avons réalisé un test au bleu de méthylène puis une cystographie rétrograde qui ont confirmé qu'il s'agissait d'une fistule provenant de la jonction urétro-vésicale. L'assèchement de la collection a été obtenu grâce à un sondage à demeure pendant plusieurs semaines.

Two types of laparoscopic or robotic-assisted vesicovaginal fistula (VVF) repairs, the traditional transvesical (O'Conor) and extravesical techniques, dominate the literature. The objectives of this study are to compare success rates between laparoscopic or robotic transvesical and extravesical laparoscopic VVF repair techniques and to evaluate the impact of the number of layers in the closure, interposition flaps, and intraoperative testing of the integrity of the bladder repair. Eligible studies, published between 1994 and March 10, 2014, were retrieved through Medline and bibliography searches. All study designs of laparoscopic/robotic VVF repair were included. Open laparotomy and vaginal approaches were excluded. Only 1 retrospective cohort study was included, with the remaining articles consisting of case reports and case series. Ultimately, only 44 studies were included in a systematic review: 9 articles of robotic-assisted approach, 3 laparoscopic single-site surgeries, and 32 conventional laparoscopic approaches. A literature review revealed a balanced number of reports for both transvesical and extravesical approaches. Statistical meta-analysis was not performed because of high heterogeneity. The overall success rate of laparoscopic VVF repair was 80% to 100% with a follow-up period of 1 to 74 months. The success rate of transvesical and extravesical techniques were 95.89% and 98.04% (relative risk, .98; 95% confidence interval, .94-1.02). There was no statistical difference in success rates of VVF repair with different number of layers in the fistula closure or with use of interposition flaps, but there was a small increase in success in the cases that documented intraoperative bladder filling to test the integrity of the bladder closure. In conclusion, transperitoneal extravesical VVF repair has cure rates similar to the traditional transvesical approach. Laparoscopic extravesical VVF repair is a safe, effective, minimally invasive technique with excellent cure rates similar to those of the conventional transvesical approach in experienced surgeons' hands.

Cervical stump cancer is a rare type of disease as total hysterectomies are performed infrequently. The purpose of this retrospective study was to assess the diagnosis, treatment, follow-up methods and complications of 10 patients with cervical stump carcinoma treated with surgery in Anhui Provincial Hospital affiliated to Anhui Medical University (Hefei, China). From January 2006 to October 2016 a total of 10 patients underwent surgery for carcinoma of the cervical stump. The pathological reports revealed 80% of cases were squamous cell carcinoma and 20% of cases were adenocarcinoma. The FIGO stage distribution was as follows: Carcinoma in situ (10%); IB1 (70%); IIA (20%). The patients received a transvaginal trachelectomy or a radical trachelectomy and pelvic lymphadenectomy (either laparoscopic or laparotomic abdominal); four of the patients were treated with adjuvant chemotherapy, and two with concurrent chemoradiotherapy. The parametrial and resection margin infiltration, lymph node metastasis and lymph vascular space invasion (LVSI) were negative in all patients, and the deep stromal invasion rate was 66.7% (6/9). No incidences of recurrence or mortality were recorded during the follow-up interval of 6–120 months. Compared with the four patients who received laparotomic abdominal surgery, significantly less blood loss was recorded for the five patients who underwent laparoscopic surgery (P0.01) or in the hospital stay duration (P>0.01) for the patients treated with laparotomic abdominal surgery and laparoscopic surgery. One patient experienced bladder fistula due to bladder over-dilation, but recovered quickly after the catheter was reinserted. Surgery for cervical stump cancer at an early-stage is a viable and safer procedure, particularly the laparoscopic approach.

Vesicouterine fistula without vaginal leakage of urine, cyclic hematuria and amenorrhea is a rare condition, identified as Youssef’s syndrome. The most common cause of this syndrome is trauma during a cesarean section. Different therapeutical approaches that include conservative treatment, fulguration, hormonal therapy and open, laparoscopic or robotic surgeries have been mentioned in the literature. Herein a case in a 37-year-old patient is reported. Conservative treatment with urinary drainage was successful because the fistula was recognized in the immediate postoperative period.

In recent years, state-of-the-art multidetector CT and magnetic resonance imaging (MRI) have been increasingly adopted to comprehensively investigate urinary tract infections (UTI) and sepsis, particularly in patients with risk factors for complicated UTI. Based upon our personal experience at a tertiary care hospital focused on treatment of infectious illnesses, this chapter reviews the CT and MRI acquisition techniques (including CT-cystography) and the cross-sectional imaging findings of lower UTIs affecting the urinary bladder, prostate and seminal vesicles, with emphasis on differential diagnoses. The list of presented disorders encompasses acute infectious and emphysematous cystitis, bladder mural abscess, bladder fistulas, acute bacterial prostatitis and prostatic and seminal vesicle abscesses. These uncommon yet potentially severe disorders are often insidious and clinically unsuspected; therefore radiologists require a high index of suspicion and thorough familiarity with their imaging appearances.

Objectives: To evaluate the efficacy and safety of pedal lymphography (PLG) in the localization diagnosis of chyluria. Methods: Cystoscopy was performed in 153 patients and PLG in 121 cases. Unilateral or staged bilateral ligation and stripping of renal lymphatic vessel were performed according to the results of cystoscopy and/or PLG. Results: Unilateral and bilateral urinary excretion of chyle was detected in 123 and 1 case by cystoscopy, respectively. In 121 cases receiving PLG, 100 cases of unilateral fistulous connection between the renal pelvis and the lymphatic system, 18 cases of bilateral fistulas and 1 case of lymphatic bladder fistula were demonstrated. PLG has a higher diagnostic rate for the detection of bilateral lymphatic renal pelvis fistulas than cystoscopy (p < 0.05). 28 cases received renal pedicle lymphatic disconnection only according to the results of cystoscopy, and 3 of them failed (10.1%). While 121 cases had the same operation according to the results of PLG, only 1 case failed the operation (0.8%). Conclusions: PLG was efficient and safe for the localization diagnosis of chyluria, with a higher detection rate of bilateral fistulas than cystoscopy. PLG might benefit the selection of appropriate therapy and improve the surgical effect.

Goal: Determine correlation between complications and stage of the disease and their impact on quality of life in patients with different types of ileal urinary derivation after radical cystectomy, and upon estimation of acquired results, to suggest the most acceptable type of urinary diversion. Patients and methods: In five year period a prospective clinical study was performed on 106 patients, to whom a radical cystectomy was performed due to bladder cancer. Patients were divided into two groups, 66 patients with ileal conduit derivation and 40 patients with orthotopic derivation, whereby in each group a comparison between reflux and anti-reflux technique of orthotopic bladder was made. All patients from both groups filled the Sickness Impact Profile score six months after the operation. All patients had CT urography or Intravenous urography performed, as well as standard laboratory, vitamin B12 blood values, in order to evaluate early (ileus or subileus, wound dehiscence, bladder fistula, rupture of orthotopic bladder, urine extravazation) and late complications (VUR, urethral stricture, ureter stenosis, metabolic acidosis, mineral dis-balance, hypovitaminosis of vitamin B12, increased resorption of bone calcium, urinary infection, kidney damage, relapse of primary disease), so as disease stage and it’s impact on quality of life. Results: From gained results we observe that each category of SIP score correlates with different rate of correlation with the type of operation, group, T, N, and R grade, except work category. Average value of SIP score rises depending on the type of operation and T stage. It is notable that there is no difference in T1 stage, no matter the type of operation. So the average value of SIP score in T1 stage for conduit was 20.3, for Abol-Enein and Ghoneim 17.25 and Hautmann 18.75 respectively. Average value of SIP score in T2 stage for conduit was 31, for Abol-Enein and Ghoneim 19.1 and Hautmann 17.8. Average value of SIP score in T3 stage for conduit was 38.03, for Abol-Enein and Ghoneim 18.75 and Hautmann 19.5. SIP score for T4 was present only in patients with conduit performed and average value od SIP score was 40.42. There is a high level of correlation of late complications and psychosocial and physical dimension with their parameters, while for an independent dimension of correlation is not significant. Early complications have insignificant correlation in all categories of SIP score. Conclusion: Upon analyzing quality of life and morbidity, significant advantage is given to orthotopic derivations, especially Hautmann derivation with Chimney modification, unless there are no absolute contraindications for performing this type of operation. Factors which mostly influence quality of life are cancer stage, type of derivation, late complications and patient age. SIP score, as a well validated questionnaire, are applicable in this kind of research.

The occurrence of a peritoneal bladder fistula as a result of radiation cystitis following radiotherapy for cervical cancer is extremely rare and, to the best of our knowledge, has not been reported previously. The present study reports the case of a 50-year-old woman who was diagnosed with cervical cancer 20 years previously and was treated with radiotherapy. The patient was diagnosed with radiation cystitis 10 years ago, which was treated with Chinese medicine, and began experiencing sudden abdominal pain and bowel difficulties following urination 3 years ago. B-ultrasound examination at The People's Hospital of Tongchuan (Tongchuan, China) detected the presence of abdominal pelvic fluid. Following antibiotic (levofloxacin for 5 days) and ascites extraction treatment, symptoms were relieved without recurrence. However, 5 days prior to admission to the First Affiliated Hospital of Xi'an Jiatong University (Xi'an, China) on June 25, 2014, the patient experienced difficulty when urinating, abdominal pain and bloating, but did not experience frequent urination, hematuria or fever. Cystoscopic examination revealed a visible fistula on the bladder wall measuring 1×1 cm in diameter. Cytoscopic examination 1 month after catheterization and ascites extraction revealed no evidence of the fistula. The patient was followed up every 3 months for a year and a half, and is currently alive and well. In conclusion, the occurrence of peritoneal bladder fistula following radiation therapy is rare and cystoscopy is the preferred method of examination and diagnosis. Early detection and treatment may significantly improve the prognosis of patients.

The operation logbook was reviewed to identify all new cases of obstetric fistula presenting from 2011 to 2015. New cases of urinary fistula were classified by fistula type (high or low), age, and parity of the woman.Results: In total, 2,593 new cases of urinary fistulae were identified in the study period. The number of new cases fell by 20% per year over the 4 years (P

Background: Patients suffering local recurrence of colorectal cancer which cannot be surgically removed are troubled with severe pain and poor quality of life. The aim of this study is to evaluate the efficacy and safety of computed tomography (CT)-guided microwave ablation (MWA) as palliative treatment for recurrent unresectable colorectal cancer. Materials and Methods: Thirty-one patients were suffering locally recurrent colorectal cancer underwent MWA with CT guidance. The MWA power was set at 60–80 W, 6–8 min. Effectiveness was evaluated by visual analog scale (VAS) with a follow-up of 6-month. Complications were also recorded. Results: Technical success was achieved in all patients. Mean VAS preprocedure was 7.10. Mean VAS postprocedure were as follows: 1 week, 2.65 (P < 0.001); 1 month, 0.81 (P < 0.001); 3 months 0.45 (P < 0.001); and 6 months 0.19 (P < 0.001). No serious complications were observed including intestinal fistulas, bladder fistulas, or peripheral vascular or nerve injury. Conclusions: CT-guided MWA as treatment of recurrent colorectal cancer can quickly and effectively relieve pain. It is a minimally invasive, safe, and efficient palliative treatment of recurrent colorectal cancer.

The authors report a case of bladder fistula associated with a medial thigh cutaneous fistula and chronic osteomyelitis of the pubic bone 11 years after surgery for a pelvic bone fracture and bladder rupture. In the presenting case, despite the clinical suspicion, none of the diagnostic tools demonstrated the bladder fistula preoperatively. This case suggests that bladder repair should be prepared, even if the bladder fistula cannot be confirmed by imaging studies because the amount of urine leakage can be minimal or the fistula can close spontaneously.
