ABSTRACT Purpose: To evaluate efficacy of urorectal fistula (URF) repair using different approaches and the clinical factor determinant of success, and also the morbidity associated to the procedure and health-related quality of life (HRQoL) in male survivors of pelvic malignancies. Material and Methods: Retrospective evaluation of 39 patients with URF primarily intervened in three institutions using different surgical approaches. Success was defined as effective fistula closure. Variables evaluated included demographics, previous treatments, surgical approach, ancillary surgeries, complications and HRQoL by using a standardized non-validated specific questionnaire. Median follow-up from surgery to interview was 55 months (interquartile range 49, range 4-112). Factors determinant of success were investigated using logistic regression. Safety of the procedure was evaluated by Clavien-Dindo scale. Deterioration of continence and erectile function and other HRQoL issues were evaluated. Results: Prostate cancer treatment was the predominant etiology. The success rate for fistula repair was 89.5%. The surgical approach was not related to failed repair (p=0.35) or complications (p=0.29). Factors associated with failure were complications (p=0.025), radiotherapy (p=0.03), fistula location (p=0.04) and fistula size (p=0.007). Multivariate analysis revealed fistula size was the only independent determinant of failure (OR 6.904, 1.01-47.75). Complications occurred in 46.2% and severe complications in 12.8%. The mortality related to the procedure was 2.6%. Urinary incontinence was present before repair in 26.3% and erectile dysfunction in 89.5%. Fistula repair caused de novo urinary incontinence in 7.9% and deterioration of erectile status in 44.7%. Globally 79% were satisfied after repair and only 7.9% rated HRQoL as unhappy. Trans-sphincteric approach was related to less deterioration of erectile function (p=0.003), and higher perceived satisfaction in QoL (p=0.04). Conclusions: The surgical approach elected to correct URF is not determinant of success nor of complications. Fistula size appears as independent determinant for failure. Transsphincteric approach could be advantageous over other procedures regarding HRQoL issues.

ABSTRACT Purpose: To develop a rabbit experimental study to test the hypothesis that surgical repair of hypospadias with severe ventral curvatures might be completed in one stage, if a graft, such as buccal mucosa, could be placed over the tunica vaginalis flap used in corporoplasty for ventral lengthening, with the addition of an onlay preputial island flap to complete the urethroplasty. Materials and methods: The experimental procedure with rabbits included a tunica vaginalis flap for reconstruction of the corpora after corporotomy, simulating a ventral lengthening operation. A buccal mucosa graft was placed directly on top of the flap, and the urethroplasty was completed with an onlay preputial island flap. Eight rabbits were divided into 4 groups, sacrificed at 2, 4, 8 and 12 weeks postoperatively, and submitted to histological evaluation. Results: We observed a large number of complications, such as fistula (75%), urinary retention (50%) and stenosis (50%). There were two deaths related to the procedure. Histological evaluation demonstrated a severe and persistent inflammatory reaction. No viable tunica vaginalis or buccal mucosa was identified. Conclusions: In this animal model, the association of a buccal mucosa graft over the tunica vaginalis flap was not successful, and resulted in complete loss of both tissues.

ABSTRACTKidney disease presenting with cutaneous fistula is a rare condition. We present a case of a 90-year-old woman with dementia who had no prior urological problems and had a cutaneous fistula in the left lumbar region. A fistulogram and computer tomography examination revealed a large staghorn calculus with signs of xanthogranulomatous pyelonephritis in the left kidney and renal fistulisation to the psoas muscle, skin and bronchi. To our knowledge this is the first report in the literature of coexisting renal fistulisation to the psoas major muscle, skin and bronchi. This report illustrates how computed tomography in combination with fistulography can resolve the diagnostic dilemma that pertains to the complex spread of the disease in cases involving nephrocutaneous fistula. Furthermore, the report shows how a renal calculus, even asymptomatic, can cause a serious medical condition, and highlights the importance of early medical intervention.

Purpose To compare retrograde dye injection through an externalized ureteral catheter with direct needle injection of dye into proximal ureter for identification of unrecognized collecting system disruption and integrity of subsequent repair during open partial nephrectomy. Materials and Methods We retrospectively reviewed the records of 259 consecutive patients who underwent open partial nephrectomy. Externalized ureteral catheters were placed preoperatively in 110 patients (Group 1); needle injection of methylene blue directly into proximal ureter was used in 120 patients (Group 2). No assessment of the collecting system was performed in 29 patients (Group 3). We compared intraoperative parameters, tumor characteristics, collecting system entry and incidence of urine leaks among the three groups. Results The mean tumor diameter was 3.1cm in Group 1, 3.6cm in Group 2, and 3.8 cm in Group 3 (p = 0.04); mean EBL 320cc, 351 cc and 376cc (p = 0.5); mean operative time 193.5 minutes, 221 minutes and 290 minutes (p < 0.001). Collecting system entry was recognized in 63%, 76% and 38% of cases in Groups 1, 2 and 3 respectively. (p = 0.07). Postoperative urine leaks requiring some form of management occurred in 11 patients from group 1 and 6 from group 2. (p = 0.2). No patient in Group 3 developed a urinary leak. Conclusions Identification of unrecognized collecting system disruption as well as postoperative urine leak rate in patients undergoing partial nephrectomy were not influenced by the intraoperative technique of identifying unrecognized collecting system entry. Postoperative urine leaks are uncommon despite recognized collecting system disruption in the majority of patients. .

La fístula nefrobronquial es una complicación infrecuente de las infecciones renales, que ocurre habitualmente en pacientes adultos con pielonefritis xantogranulomatosa. Comunicamos el caso de una paciente de 12 años con antecedentes de mielomeningocele operado e infección urinaria recurrente, quien consultó con historia de cuatro semanas de fiebre, tos y disnea. Ingresó en shock séptico y presentó inundación de la vía aérea por pus, que le ocasionó episodio de asistolia. Mediante tomografía computarizada de abdomen, se diagnosticó extensa colección perirrenal izquierda. Se efectuó un drenaje percutáneo, que dio salida a pus y aire. TAC de tórax y abdomen mostró fístula transdiafragmática entre la base pulmonar izquierda y colección intraabdominal. Se realizó nefrectomía total. La paciente mostró mejoría progresiva poscirugía y regresión total de la sintomatología. Este infrecuente caso clínico en niños ilustra la importancia del diagnóstico precoz de infección urinaria en pacientes con patologías asociadas y de presentar un elevado índice de sospecha ante una complicación potencialmente letal

Nephrobronchial fistula is a rare complication of kidney infections, usually occurring in adult patients with xanthogranulomatous pyelonephritis and very occasionally in children. We reported a 12-year-old girl, with a history of myelomeningocele and recurrent urinary tract infection, who presented with a four-week fever, cough and dyspnea, developing septic shock and presenting flood of airway by pus which caused cardiac arrest. A diagnosis of left perirenal extensive collection was established by abdominal computed tomography (CT). The patient first had antibiotic therapy and percutaneous drainage was performed draining pus and air. Thoracic and abdominal CT scan was performed corroborating transdiaphragmatic fistula. Total nephrectomy was performed. The patient showed gradual improvement after surgery and total regression of symptoms. Pathologic examination concluded chronic pyelonephritis. This case report illustrates a rare complication in children, the importance of early diagnosis of urinary tract infection in patients with comorbidities and of exhibiting a high index of suspicion to a potentially lethal complication.

Se presenta el caso de un paciente masculino quien requirió tratamiento por agenesia anorrectal con fístula rectouretral y transposición pene-escrotal con hipospadias perineal, acompañados de una masa perineal. La tumoración perineal se encontró íntimamente adherida y en continuidad al recto, lo que la hace compatible con una duplicación rectal extrofiada. La reconstrucción quirúrgica de la anomalía se realizó en etapas hasta lograr resultados funcionales y estéticos aceptables.

We present the case of a male patient who required treaatment due to anorectal agenesis with recto urethral fistula and penoscrotal transposition with perineal hypospadias, associated with a perineal tumor. The perineal tumor was found strongly adhered and contiguous to the rectum which makes it compatible with an exstrophy of rectal duplication. Surgical reconstruction of the birth defect was performed in stages until acceptable biological function and esthetic results were obtained.

OBJETIVO: analisar complicações, morbidade, mortalidade e sobrevida num grupo de pacientes com câncer de colo uterino com recidiva pélvica central submetidas à exenteração pélvica pós-tratamento primário com radioterapia. MÉTODOS: estudo retrospectivo de uma série de 16 casos de exenteração pélvica pós-tratamento primário com radioterapia. Foi realizada estatística descritiva, curva de sobrevida pelo método de Kaplan-Meier e análise de regressão linear múltipla para avaliar fatores prognósticos. RESULTADOS: dezesseis pacientes foram submetidas à exenteração pélvica. O carcinoma epidermoide, o estádio IIb e o grau indiferenciado foram as condições mais frequentes. A recidiva tumoral pós-operatória ocorreu na metade dos casos. Onze pacientes apresentaram complicações perioperatórias ou pós-operatórias e as mais frequentes foram infecções pélvica e da ferida operatória e fístulas urinárias. A sobrevida global foi de 64,3 por cento, com um seguimento mediano de 11 meses. A análise de regressão linear múltipla não revelou fatores prognósticos significativos na sobrevida das pacientes. CONCLUSÕES: a taxa de sobrevida foi de 64,3 por cento. Nenhum fator associado a pior prognóstico foi encontrado nesta série.

PURPOSE: to analyze complications, morbidity, mortality and survival rate in a group of patients with cervical cancer with central pelvic relapse after primary radiotherapy treatment. METHODS: retrospective study of a series of 16 cases of pelvic exenteration after primary radiotherapy treatment. Descriptive statistics, survival curve through Kaplan-Meier's method, and regression analysis to evaluate prognosis were performed. RESULTS: sixteen patients have undergone pelvic exenteration. Epidermoid carcinoma, IIb stage and undifferentiated grade were the most frequent conditions. Post-operatory tumor relapse occurred in half the cases. Eleven patients presented peri or post-surgical complications, the most frequent being pelvic infection, that of the surgical wound, and urinary fistulae. Global survival rate was 64.3 percent, with average follow-up of 11 months. Regression analysis did not detect any significant prognosis factor for the patient survival. CONCLUSIONS: the survival rate was 64.3 percent. No particular factor associated to poor prognosis has been found in the present series of cases.

OBJETIVO: As fístulas vesicovaginais e ureterovaginais são complicações incomuns, secundárias a doenças ou a cirurgias pélvicas. O sucesso terapêutico dessas fístulas depende de adequada avaliação pré-operatória para o diagnóstico e visualização do seu trajeto. Este trabalho tem o objetivo de demonstrar o potencial da urorressonância no diagnóstico das fístulas urogenitais e na visualização dos seus trajetos. MATERIAIS E MÉTODOS: Foram analisados, retrospectivamente, os prontuários médicos e as imagens radiológicas e de urorressonância magnética de sete pacientes do sexo feminino com diagnóstico de fístula urogenital. Para a urorressonância foram realizadas seqüências 3D-HASTE com saturação de gordura. RESULTADOS: Seis pacientes apresentavam fístula vesicovaginal e uma paciente tinha diagnóstico de fístula ureterovaginal à direita. Com a utilização da urorressonância magnética, foi possível demonstrar o trajeto da fístula em seis das sete pacientes (85,7 por cento), sem a necessidade de cateterização vesical ou da injeção de contraste. CONCLUSÃO: Este estudo demonstra o potencial e a aplicabilidade da urorressonância na avaliação dessas fístulas.

OBJECTIVE: Vesicovaginal and ureterovaginal fistulas are unusual complications secondary to pelvic surgery or pelvic diseases. The therapeutic success in these cases depends on an appropriate preoperative evaluation for diagnosis and visualization of the fistulous tract. The present study is aimed at demonstrating the potential of magnetic resonance urography for the diagnosis of vesicovaginal and ureterovaginal fistulas as well as for defining the fistulous tracts. MATERIALS AND METHODS: Seven female patients clinically diagnosed with vesicovaginal or ureterovaginal fistulas had their medical records, radiological and magnetic resonance images retrospectively reviewed. Magnetic resonance urography included 3D-HASTE sequences with fat saturation. RESULTS: Six patients presented vesicovaginal fistulas and, in one patient, a right-sided ureterovaginal fistula was diagnosed. Magnetic resonance urography allowed the demonstration of the fistulous tract in six (85.7 percent) of the seven patients evaluated in the present study, without the need of bladder catheterization or contrast injection. CONCLUSION: This study demonstrates both the potential and applicability of magnetic resonance urography in the evaluation of these types of fistulas.

To determine incidence of different types of urogenital fistulae, their frequency and success rate of different methods of repair. This descriptive study was conducted at Armed Forces Institute of Urology and Department of Obstetrics and Gynecology, Military Hospital Rawalpindi from January 1997 to January 1998. A total of 44 patients were included in the study. Diagnosis was made by taking comprehensive history, detailed examination and appropriate investigations. Data regarding aetiological and risk factors was gathered. The incidence was 0.26%. Obstetric trauma, mostly prolonged and obstructed labour, was responsible for 53.3% cases and 40% were result of surgical trauma and miscellaneous causes. Forty percent of fistulae were vesico vaginal and same number was simple in type. Nearly 55% were repaired by abdominal route and 75% were successful in 1[st] attempt. Obstetric trauma was the commonest cause of urogenital fistulae. Majority were repaired by abdominal route and 75% were successful in first attempt. Improvement in maternity care in rural areas, easy approach to specialist care and better training of staff in instrumental deliveries may help to decrease the incidence of these fistule

A ruptura ou fistulização de vasos linfáticos para o interior do sistema excretor urinário dá origem à quilúria, que tem na bancroftose a sua principal etiologia. Pode ser, raramente, também causada por neoplasia, malformação linfática, traumatismo abdominal, assim como outras doenças infecciosas como a tuberculose. Os autores propõem as diretrizes gerais para a condução do portador de "urina leitosa" em áreas endêmicas e não endêmicas de filariose bancroftiana. Ressaltam a importância dos exames de triagem e de outros mais sofisticados para uma investigação etiológica a partir da realização de anamnese e de exame físico criteriosos. Enfatizam a necessidade de que a doença deve ser conduzida através de uma abordagem mais abrangente, que compreenda, além da médica, a assistência social e a nutricional. Na grande maioria dos casos, o controle da quilúria está basicamente fundamentado na educação e na adequação do paciente a uma dieta hipolipídica/hiperprotéica e rica em líquidos.

The rupture or fistulization of lymph vessels into the urinary system, known as chyluria (milky urine), is caused mainly by bancroftian filariasis. On rare occasions chyluria may also be caused by neoplasia, lymphatic malformation, abdominal trauma, as well as other infectious diseases such as tuberculosis. The authors proposed general guidelines to manage patients suffering from milky urine in Bancroftian filariasis endemic and non-endemic areas. They emphasized the importance of a careful diagnostic process accomplished using screening procedures, evaluating a detailed history of illness and performing a careful physical examination, targeting on the most suitable diagnostic tools for each case. In addition, they emphasized the need to manage the patient from a broader perspective, which goes beyond the medical aspect, involving also social and nutritional contexts. In the great majority of cases, controlling chyluria is fundamentally based on patient education and adjustment to a low lipid, high protein diet in addition to increased fluid intake.

OBJECTIVE: Recto-urethral fistula formation following radical prostatectomy is an uncommon but potentially devastating event. There is no consensus in the literature regarding the treatment of these fistulas. We present here our experiences treating recto-urethral fistulas. MATERIAL AND METHODS: We analyzed 8 cases of rectourethral fistula treated at our institution in the last seven years. Seven of the patients underwent repair of the fistula using the modified York-Mason procedure. RESULTS: The causes of the fistula were radical retropubic prostatectomy in five patients, perineal debridement of Fournier's gangrene in one, transvesical prostatectomy in one and transurethral resection of the prostate in the other patient. The most common clinical manifestation was fecaluria, present in 87.5 percent of the cases. The mean time elapsed between diagnosis and correction of the fistula was 29.6 (7-63) months. One spontaneous closure occurred after five months of delayed catheterization. Urinary and retrograde urethrocystography indicated the site of the fistula in 71.4 percent of the cases. No patient presented recurrence of the fistula after its correction with the modified York-Mason procedure. CONCLUSION: The performance of routine colostomy and cystostomy is unnecessary. The technique described by York-Mason permits easy access, reduces surgical and hospitalization times and presents low complication and morbidity rates when surgically correcting recto-urethral fistulas.

OBJETIVO: As fístulas reto-uretrais são de acesso difícil e por vezes complexo, sendo seu fechamento espontâneo raro. Com o diagnóstico precoce e aumento do número de intervenções, principalmente a cirurgia por adenocarcinoma da próstata localizado, sua incidência apesar de rara vem crescendo. Nós demonstramos a nossa experiência dos casos de fístulas reto-uretrais entre 2000 a 2006 com uma serie de oito pacientes, sendo que sete realizaram correção da fístula pela Técnica de York Mason modificada. MATERIAL E MÉTODO: Nos retrospectivamente analisamos os prontuários de todos os casos de fístulas reto-uretrais tratados no nosso serviço no período de 2000 a 2006. Sete de oito pacientes realizaram reparo da fístula através do procedimento de York Mason modificado. RESULTADOS: Cinco pacientes tiveram a fístula como conseqüência da Prostatectomia Radical Retropúbica, sendo os outros três após debridamento devido a Fasceíte de Fournier, Prostatectomia Transvesical e Ressecção Transuretral da Próstata. A fecalúria foi o quadro clínico prevalente em 87,5 por cento dos casos, o tempo médio entre o diagnóstico e a correção da fístula foi de 29,6 (7-63 meses) ocorreu um fechamento espontâneo após cinco meses de sondagem vesical de demora, a Uretrocistografia Retrograda e Miccional demonstrou a localização da fístula em 71,4 por cento. Nenhum paciente apresentou recidiva da fístula após correção pela técnica de York Mason modificada. A colostomia foi realizada em 50 por cento dos casos e não ocorreram casos de incontinência fecal ou estenose anal. CONCLUÇÃO: Após identificação de fístula reto-uretral, não é necessário à realização de colostomia e cistostomia de rotina. Sua correção pela técnica descrita por York Mason modificada nos propicia fácil acesso a sua localização, diminui o tempo cirúrgico e de internação, com baixos índices de complicações e morbidade.

OBJECTIVES: urinary fistula is a morbid complication after renal transplantation leading to graft losses and patient death. We review and update our data on urinary fistula after renal transplantation and the outcome after surgical and conservative management. MATERIALS AND METHODS: the charts of 1046 renal transplants were reviewed. Transplants were performed through an extended inguinotomy; vascular anastomoses to the iliac vessels and urinary reconstruction accomplished through the Gregoir technique. Fistulae were diagnosed by urinary leaks through the incision or by the occurrence of a collection in the iliac fossa. Patient was treated surgically or conservatively according to the characteristics of the fistula and patient clinical status. RESULTS: Thirty one fistulae were diagnosed (2.9 percent). Twenty nine leaks due to ureteral necrosis and 2 due to reimplantation fault. The incidence of leaks among cadaver and live donor transplants was 3.22 percent and 2.63 percent, respectively (p = 0.73). Among diabetic and non diabetic patients the incidence of urinary leaks was 6.4 percent and 2.6 percent, respectively (p = 0.049). Treatment consisted in anastomosis of the graft ureter or pelvis with the ureter of the recipient in 17 cases with success in 13 (76.5 percent). Prolonged bladder drainage was employed in 7 cases and the fistula healed in 4 (57 percent). Ureteral reimplantation was performed in 3 cases and did not work in any of them. Ureteral ligature plus nephrostomy was employed in two cases and worked in one (50 percent). Percutaneous nephrostomy and ureteral stenting with double J catheter were employed in one case each and worked in both. CONCLUSIONS: The anastomosis of the graft ureter with the ureter of the recipient is a good method for treating urinary fistulae after renal transplantation when local and systemic conditions are good. Ureteral ligature associated to nephrostomy should be applied in cases of unfavorable local conditions or clinically unstable patients.

Se presentan 58 pacientes entre 24 y 65 años, con una edad media de 44,5 años, las que sufrieron lesiones ureterales, en cirugías ginecológicas. Presentaron fístulas ureterovaginales 50 pacientes, lo que significó el 86,2 por ciento. Hubo dos pacientes con fístulas bilaterales, 4 ligaduras de uréteres y 2 fístulas a cavidad. La etiología predominante fue histerectomía simple en casi 69 por ciento e histerectomía ampliada en 24 por ciento. No hubo por causas obstétricas. La soluciones se implementaron inmediatamente de hecho el diagnóstico y sin nefrostomías previas, salvo excepciones, en pacientes en mal estado general, derivadas de otros centros. Se realizó 28 ureteroneocistostomías con técnica de Leadbetter-Politano. A 24 pacientes se les hizo colgajo vesical con técnica de Boari Cassatti y además en un caso fue bilateral.
