Arterio-Ureteral Fistula: Systematic Review of 445 Patients.

PURPOSE: Arterio-ureteral fistula (AUF) is an uncommon diagnosis, but increasingly reported and potentially lethal. This systematic review comprehensively presents risk factors, pathophysiology, location and clinical presentation of AUF aiming to increase clinical awareness of this rare but life-threatening condition, and to put this entity into a contemporary perspective with modern diagnostic tools and treatment strategies. MATERIALS AND METHODS: This review was performed according to the PRISMA (Preferred Reporting Items for a Systematic Review and Meta-Analysis of Individual Participant Data) guidelines. A literature search in PubMed® and EMBASE™ was conducted. In addition, retrieved articles were cross-referenced. Data parameters included oncologic, vascular and urological history, diagnostics, treatment, and followup, and were collected using a standard template by 2 independent reviewers. RESULTS: A total of 245 articles with 445 patients and 470 AUFs were included. Most patients had chronic indwelling ureteral stents (80%) and history of pelvic oncology (70%). Hematuria was observed in 99% of the patients, of whom 76% presented with massive hematuria with or without previous episodes of (micro)hematuria. For diagnosis, angiography had a sensitivity of 62%. The most predominant location of AUF was at the common iliac artery ureteral crossing. AUF-specific mortality before 2000 vs after 2000 is 19% vs 7%, coinciding with increasing use of endovascular stents. CONCLUSIONS: AUF should be considered in patients with a medical history of vascular surgery, pelvic oncologic surgery, irradiation and/or chronic indwelling ureteral stents presenting with intermittent (micro)hematuria. A multidisciplinary consultation is necessary for diagnosis and treatment. The most sensitive test is angiography and the preferred initial treatment is endovascular.

Impacto en la calidad de vida del tratamiento del cáncer de próstata organoconfinado / Impact of organ confined prostate cancer treatment on quality of life

INTRODUCCIÓN: El cáncer de próstata (CP) es el segundo cáncer más frecuente del mundo y en los varones. Se estima que la incidencia crezca a 1,7 millones de casos nuevos y 499.000 nuevas muertes en 2030. El tratamiento del cáncer de próstata organoconfinado (CPOC) puede afectar a un individuo tanto física como mentalmente, así como sus relaciones cercanas y su trabajo o vocación, lo cual condiciona la calidad de vida (CV) relacionada con la salud. OBJETIVO: Conocer el impacto en la CV atribuible al tratamiento del CPOC. MATERIALES Y MÉTODOS: Es un estudio observacional multicéntrico de carácter prospectivo de 406 pacientes con CPOC tratados desde enero del año 2015 hasta junio del 2018. La muestra se dividió en cuatro grupos de estudio (GA, GB, GC y GD), correspondientes a los distintos métodos de abordaje quirúrgico: prostatectomía radical (PR), radioterapia externa (RTE), braquiterapia (BT) y diferente a monoterapia con alguno de los otros, respectivamente. RESULTADOS: La edad en el GC fue inferior, la media del antígeno prostático específico (PSA, prostatic specific antigen) de todos los pacientes fue 8,13 ng/ml, el grupo de mayor media de PSA fue el GB con 10,43 ng/dL, la media del estadio tumoral (TNM,) fue 3,82, la CV postratamiento en GD fue inferior respecto a los demás grupos. CONCLUSIÓN: El tratamiento del CPOC afecta la CV La monoterapia curativa, concretamente la PR y la BT, afectan menos a la CV que la radioterapia externa u otras alternativas terapéuticas. La incontinencia urinaria y las fístulas secundarias al tratamiento del CPOC son las que producen más deterioro en la CV. El cuestionario SF 36 validado internacionalmente es una medida transversal de la CV, útil para comparar el impacto de los tratamientos del CPOC

INTRODUCTION: Prostate cancer (PCa) is the second most common male cancer in the world. Its incidence is estimated to grow to 1.7 million new cases and 499,000 new deaths by 2030. Treatment of OCPC can affect patients physically and mentally, as well as their close relationships and their job or career, which conditions health-related quality of life (QoL). OBJECTIVE: Evaluate the impact on QoL attributable to the treatment for Organ Confined Prostate Cancer (OCPC). MATERIALS AND METHODS: Prospective multicenter observational study of 406 patients with OCPC treated from January 2015 to June 2018. The sample was divided into four study groups, according to the type of treatment: radical prostatectomy (RP) (GA), external radiotherapy (ERT) (GB), brachytherapy (BT) (GC) and other treatments different from monotherapy with RP, ERT or BT (GD). RESULTS: The age in GC was lower, the mean Prostate Specific Antigen (PSA) of all patients was 8.13 ng/ml, the group with the highest mean PSA was GB with a mean of 10.43 ng/dL, the mean Tumor Stage (TNM) was 3.82, and GD had the lowest post treatment quality of life. CONCLUSION: OCPC treatment affects QoL. Curative monotherapies, specifically RP and BT, have less effect on QoL than external radiotherapy or other therapeutic alternatives. Urinary incontinence and fistulas secondary to OCPC have the highest impact on QOL impairment. The internationally validated SF 36 questionnaire is a useful cross-sectional measure of QOL to compare the impact of OCPC treatment modalities

Functional outcome and quality of life evaluation of graciloplasty for the treatment of complex recto-vaginal and recto-urethral fistulas.

Recto-vaginal (RVF) and recto-urethral (RUF) fistulas are infrequent but disabling conditions that severely affect patients' quality of life. Considering the high recurrence rate after conservative approaches, the best surgical treatment is still challenging. The aim of this study was to evaluate the outcome of graciloplasty to treat patients with complex RVF or RUF, and to investigate its effect on the quality of life. Fourteen patients with RVF and RUF who underwent graciloplasty between 2003 and 2017 were retrospectively enrolled. The main outcome was the healing rate of fistulas. Postoperative patients satisfaction was evaluated administering the Clinical Patient Grading Assessment Scale (CPGAS), SF-36 questionnaires and Changes in Sexual Functioning (CSF) questionnaires. The Wexner score was calculated in case of preoperative faecal incontinence. RVF and RUF were iatrogenic in 11 patients and due to Crohn's disease in 3 cases. After 1 year of follow-up (IQR 10-14 months), the success rate of the procedure was 78%. Out of three patients with RVF due to Crohn's disease, two healed after the procedure. Six months after surgery, all eight SF-36 domains significantly improved except for "body pain"; CSF score significantly increased from 35.5 (IQR 31-38.7) to 44 (IQR 37.7-48.5); CPGAS score improved from a median value of 0 (IQR 0-0) to 4 (IQR 3.2-4). The Wexner score was calculated only in 5 patients with preoperative faecal incontinence and it significantly decreased from a median value of 12 (IQR 11-14) to 5 (IQR 4-5). Graciloplasty could be considered as a first option treatment for complex or recurrent RVF and RUF. It shows a good healing rate even in case of unfavourable factors like Crohn's disease.

Transrenal Ureteral Occlusion for Palliation of Refractory Urine Leaks Using Vascular Plugs and Liquid Ethylene Vinyl Alcohol.

PURPOSE: To describe outcomes of transrenal embolization with vascular plugs and ethylene vinyl alcohol (EVOH) in a case series of patients with refractory urinary leak or fistula. MATERIALS AND METHODS: Fifteen ureteral occlusions performed over 53 months in 9 consecutive patients (56% female; mean age 61 y; range, 45-80 y) were reviewed retrospectively. The main indication was palliation for refractory fistula or leak in the setting of malignancy not responding to urine diversion by percutaneous nephrostomy tube or nephroureteral stent. Transrenal ureteral occlusion was performed using EVOH injected between vascular plugs placed distal and proximal to the leak or fistula. RESULTS: Technical success was 100%. Considerable reduction of urine leak or symptoms (clinical success) was achieved in 64% of ureters after mean follow-up of 105 days (range, 0-632 d). Complete ureteral occlusion on follow-up anterograde nephrostogram (imaging success) was achieved in 60% of ureters after mean follow-up of 139 days (range, 0-643 d). One patient with distal ureterovesical junction-perineal fistula had continued leak despite complete proximal occlusion of ureter owing to retrograde urine reflux from the bladder and was treated with endoscopic injection of intramural calcium hydroxyapatite to the ureteral segment distal to the fistula. Three ureters (33%) in 2 patients with vesicovaginal fistula had recanalization, requiring additional proximal embolization, yielding secondary success rates of 91% (clinical) and 90% (imaging) per ureter. One minor urinary tract infection and no major complications occurred. CONCLUSIONS: Transrenal anterograde ureteral occlusion using EVOH between vascular plugs could be considered a relatively safe and potentially valuable treatment option for refractory ureteral fistulae.

Enhanced recovery after surgery protocol for prostate cancer patients undergoing laparoscopic radical prostatectomy.

OBJECTIVE: To determine the value of an enhanced recovery after surgery (ERAS) protocol for prostate cancer patients undergoing laparoscopic radical prostatectomy (LRP). METHODS: We conducted a retrospective cohort study using clinical data for 288 patients who underwent LRP in our hospital from June 2010 to December 2016. A total of 124 patients underwent ERAS (ERAS group) and the remaining 164 patients were allocated to the control group. ERAS comprised prehabilitation exercise, carbohydrate fluid loading, targeted intraoperative fluid resuscitation and keeping the body warm, avoiding drain use, early mobilization, and early postoperative drinking and eating. RESULTS: The times from LRP to first water intake, first ambulation, first anal exhaust, first defecation, pelvic drainage-tube removal, and length of hospital stay (LOS) were all significantly shorter, and hospitalization costs and the incidence of postoperative complications were significantly lower in the ERAS group compared with the control group. No deaths or reoperations occurred in either group, and there were no readmissions in the ERAS group, within 90 days after surgery. CONCLUSION: ERAS protocols may effectively accelerate patient rehabilitation and reduce LOS and hospitalization costs in patients undergoing LRP.

Identifying Outcomes in Clinical Trials of Fistulizing Crohn's Disease for the Development of a Core Outcome Set.

Fistulizing complications develop in approximately one third of patients with Crohn's disease (CD), resulting in morbidity and impaired quality of life.1 Sites of fistulae most commonly include perianal fistulae, but also enterocutaneous, enteroenteric, enterovesical, and rectovaginal. Its management requires combined medical and surgical strategies to prevent abscess formation and induce healing. Biologic agents have improved the medical treatment of CD-related fistulae, but many patients still require surgical intervention. Hence, there is considerable interest in the development of novel pharmaceutical agents to treat fistulizing CD.

Outcomes and Quality of Life Among Men After Anal Sphincter-Sparing Transperineal Rectourethral Fistula Repair.

OBJECTIVE: To describe long-term quality of life (QOL) outcomes after rectourethral fistula (RUF) repair. RUF is a debilitating diagnosis and complex surgical dilemma with limited data regarding QOL after repair. METHODS: Patients at a tertiary referral center undergoing transperineal RUF repair 1/2009-5/2016 were analyzed. Patients were contacted by telephone to assess QOL following repair. Descriptive analysis performed of short-term surgical data (success and complications) and long-term QOL data (novel questionnaire). RESULTS: Twenty one men underwent RUF surgery with 95% success after initial repair. Fifty two percent had a history of radiation and/or ablation. Four individuals (19%) experienced a Clavien-Dindo complication within 30 days, with 3 of those being grade III+. Fifteen had postoperative urinary incontinence, of whom 73% underwent artificial urinary sphincter placement. Three previously radiated individuals underwent subsequent urethral stricture surgery. At long-term follow-up (mean 45.6 ± 27.1 months), 53% reported perineal pain, 43% reported problems related to the gracilis flap, and 80% reported urinary incontinence (primarily occasional mild leakage). Twenty one percent were unable to do the things they wanted in their daily lives, while 80% reported that surgery positively impacted their life. None would have opted for complete urinary diversion. CONCLUSION: RUF repair leads to patient satisfaction and improved QOL, despite possible residual issues such as perineal pain and urinary incontinence. Definitive RUF repair should be offered to suitable radiated and nonradiated patients.

Otras lesiones radiológicas del tracto urinario inferior (TUI) en pacientes sometidos a radioterapia pélvica en monoterapia y combinada con cirugía / Other radiological lesions of the Lower Urinary Tract in patients after isolated pelvic radiotherapy and combined with surgery

El estudio cistográfico en pacientes sometidos a radioterapia (RTP) y cirugías pélvicas es infrecuente en la literatura, no descrita en pacientes sin complicaciones, referidas fundamentalmente a fístulas urinarias. OBJETIVO: Estudio cistográfico del TUI, en estos pacientes, con descripción de otros tipos de lesiones radiológicas. MÉTODOS:127 cistografías (88 hombres y 39 mujeres), en pacientes consecutivos sometidos a RTP (monoterapia 48, con cirugía 79), edad media 69,6 años, y tiempo medio desde la radiación 215 meses (17 años) (frente a grupo control), mediante equipo General Electric®, estudiando: comportamiento del cuello vesical en reposo y durante la micción, valoración de reflujo vésico-ureteral (RVU), morfología vesical (MV), estenosis uretrales (EU) y fístulas (F). RESULTADOS: Se observa incompetencia del cuello vesical al llenado (ICV) (37,8%), morfología vesical lisa y uniforme (60,6%), apertura miccional del cuello normal (96,1%), incontinencia urinaria a la tos (IU) (26,4%), cistocele basal (64,7%) y en Valsalva (96,6%) de las mujeres, así como disminución de la luz uretral miccional (41,3%) y RVU (13,2%). 5 casos de ICV al llenado, todos cáncer de próstata (CP) (uno de ellos también cáncer de colon). 6 fístulas (4,14%), 5 mujeres . 42 pacientes (28,96%) disminución de la luz uretral, 35 uretra posterior (83%), 5 (11,90%) anterior aislada (11,90%) y 2 mixtos (5%). El 95 % eran pacientes con CP y sin intervenciones concurrentes (67%). Se encontraron diferencias significativas de hombres vs mujeres (ICV al llenado (p = 0,007), morfología vesical irregular (p = 0,004) y disminución de luz uretral (p < 0,001) más frecuente en hombres, e IU (p = 0,007) en mujeres ) y entre pacientes con/sin intervenciones pélvicas: ICV (p = 0,046), RVU (p = 0,02), IU a la tos (p = 0,03) (más frecuentes en pacientes intervenidos) y disminución de la luz uretral (p < 0,01) (menos frecuente). Los pacientes con RVU presentan mayor tiempo transcurrido desde la radioterapia, no así en otras variables cistográficas. CONCLUSIONES: La RTP se relacionó con incompetencia del cuello, IU de esfuerzo, estenosis uretral anterior y RVU. La cirugía incrementó el factor de riesgo en pacientes intervenidos

INTRODUCTION: The cystographic study of patients who have undergone radiotherapy (RT) and pelvic surgeries is uncommon in the literature, not described in patients without complications, and mostly related to urinary fistulae. OBJECTIVE: The study of the lower urinary tract (LUT) by cystography in these patients, with a description of some other types of radiation lesions. METHODS: 127 cystographies have been performed (88 and 39 ) in consecutive patients undergoing radiotherapy (RT) (48 monotherapy and 79 cases combined with surgery), with a mean age of 69.6 years, and a mean time from radiation of 215 months (17 years). A General Electric X ray equipment has been used. We studied: behavior of the bladder neck at rest and during micturition, assessment of vesicoureteral reflux (VUR), bladder morphology (BM), urethral strictures (UE) and fistulas (F). RESULTS: We observed: Filling phase bladder neck incompetence (BNI) (37.8%), bladder smooth morphology (60.6%), coughing urinary incontinence (UI) (26.4%), basal cystocele (64.7%) and Valsalva cystocele (96.6%), a normal opening bladder neck (96,1%), reduction of the urethral diameter during voiding (41.3%), and vesicoureteral reflux (VUR) (13.2%). Five cases of filling BNI, were all related to prostate cancer (PC) (one of them with colon cancer as well). There were six cases of fistulae (4.14%), five of them women. Forty two patients (28.96%) had reduced urethral lumen, thirty five of them affecting the posterior urethra (83%), five (11.9%) the anterior and, finally, two cases of mixed lesion (5%). 95% were patients with PC without concurrent interventions (67%). Significant differences were found regarding the gender and the background of pelvic surgery. The filling BNI (p = 0.007), the irregular bladder morphology (p = 0.004) and the reduction of the urethral lumen (p < 0.001) have been found to be more common in male patients, while the coughing UI was more common in women (p = 0.007). The study shows that BNI (p = 0.046), VUR (p = 0.02) and the IU due to cough (p = 0.03) were more frequent in operated patients, while reduced urethral lumen was less common (p < 0.01). Patients with VUR present more time from radiotherapy, but not in other cystography variables. There was a relationship between RT and the BNI, stress urinary incontinence, anterior urethral stricture and VUR. The risk factor was increased by surgery. CONCLUSIONS: Bladder neck incompetence, stress UI, anterior urethral stricture and VUR have been related to radiotherapy. Surgery increased the risk factor in operated patients

Long-term functional outcomes following non-radiated urethrovaginal fistula repair.

OBJECTIVE: To review long-term functional outcomes after urethrovaginal fistula (UVF) repair. MATERIALS AND METHODS: Following IRB approval, women who underwent transvaginal non-irradiated UVF repair with minimum 6-month follow-up were reviewed. Surgical outcomes were assessed by validated questionnaires: UDI-6, IIQ-7, FSFI and visual analogue scale for QoL. Two groups were compared: (1) synthetic sling-related versus (2) non-sling-related UVF. Descriptive statistics were applied with p < 0.05 for significance. RESULTS: From 1996 to 2013, 18 patients underwent UVF repair, with a mean age of 46 years (range 20-66), BMI 29 (range 21-42) and mean follow-up at 52 months (range 9-142). Overall repair success rate was 95%. Prior failed UVF repair was recorded in 11 women (61%). Statistical differences noted for Q4: 1.9 versus 0.8 (p = 0.03) and Q5: 1.3 versus 0 (p = 0.02) and VAS between the two groups, favoring the non-sling group; 1.5 (0.6) versus 5 (4) (p = 0.05). No differences in IIQ-7 were noted between the two groups (p = 0.09). Of the 18 patients, 5 remained sexually active and of those, 2 responded to FSFI (40%) with low scores. Reoperation rate was 33% (6 women) with 3 requiring periurethral-bulking agent for recurrent SUI, 2 transurethral laser for residual urethral sling mesh strands and 1 urethral dilation. CONCLUSION: This large contemporary series of non-radiated UVF indicates a satisfactory outcome in UVF closure repair at a mean 4- to 5-year long-term follow-up, with the synthetic sling-related group performing worse.

Ureteroarterial fistula: A review of the literature.

Ureteroarterial fistulas are rare, erosive defects that occur between the distal segments of the ureter and the adjacent blood vessels in individuals with urologic and vascular comorbidities. Characterized by diffuse, pulsatile bleeding into the urinary tract, this condition carries a significant mortality rate in the absence of early recognition. Recent treatment efforts have focused on use of endovascular stenting techniques as an alternative to open surgical closure of the underlying defects in hemodynamically stable patients. We provide a literature review detailing the characteristics, mechanism, and management of ureteroarterial fistulas.

Long-term Artificial Urinary Sphincter Outcomes Following a Prior Rectourethral Fistula Repair.

OBJECTIVE: To determine the long-term outcomes of artificial urinary sphincter (AUS) implantation following a successful rectourethral fistula (RUF) repair. MATERIALS AND METHODS: Between January 1, 2006 and January 1, 2012, a total of 26 patients underwent successful repair of an RUF. Stress urinary incontinence was treated in 6 patients (23%) with implantation of an AUS. Preoperative and postoperative evaluation included demographic variables, voiding diaries, 24-hour pad weight, urodynamic characteristics, operative time, estimated blood loss, complication rates, follow-up time, and cuff selection. RESULTS: All 6 patients underwent successful RUF repair using a perineal approach. Mean age was 64.3 years (range 58-74). Mean follow-up after repair was 51.5 months (range 34-64). RUF etiology included radical prostatectomy (4), brachytherapy + external beam radiotherapy (1), and cryotherapy + external beam radiotherapy (1). The median time between RUF repair and AUS placement was 12 months (range 2-41). No intraoperative complications occurred during AUS implantation. The average operative time was 61.8 minutes with an estimated blood loss of 24 mL. The initial cuff size selected was 4.0 or 4.5 cm, and no patient required transcorporal cuff placement. Pad use was reported as ≤1 pad per day in all 6 patients at the initial 3-month follow-up. Median follow-up after AUS placement was 43.5 months (5-55). No patient required revision or removal for mechanical complications, infection, or erosion. No patient had recurrence of their previously repaired RUF or new-onset fecal incontinence. CONCLUSION: Patients who require placement of an AUS after an RUF repair seem to fare just as well as patients who undergo primary AUS implantation with no increased rate of complications postoperatively.

Ureteroarterial fistula: diagnosis and management.

OBJECTIVE: Ureteroarterial fistula (UAF) is an uncommon condition with only approximately 150 cases reported in the literature. Patients typically present with hematuria in the setting of prolonged ureteral stenting, prior pelvic surgery, malignancy, or radiation. Presentation can vary from intermittent hematuria to life-threatening hemorrhagic shock. CONCLUSION: Recognizing this condition in a prototypical patient is essential for accurate diagnosis and management. Angiography yields the highest diagnostic benefit, and arterial stent-graft placement is the treatment of choice.

Transrenal ureteral occlusion using the Amplatzer vascular plug II: a new interventional treatment option for lower urinary tract fistulas.

PURPOSE: This study was designed to evaluate the results of a novel technique for transrenal ureteral occlusion using an Amplatzer vascular plug (AVP) II in patients with urinary fistulas. METHODS: We retrospectively evaluated the results of transrenal occlusion of 15 ureters in 9 hospitalized patients [8 females, 1 male, mean age 64 (range 52-79) years] suffering from pelvic malignancy (4 cervix-carcinomas, 3 bladder-carcinomas, 1 colorectal carcinoma, and 1 vulva-carcinoma). Seven patients were treated for urinary fistulas (4 ureteroenteral, 3 vesicovaginal); the others showed ileum-conduit-insufficiency and Mainz-pouch incontinence, respectively. From 2008 to 2009, an AVP was used in combination with coils and tissue adhesive (n = 5). Since 2009, ureteral occlusions were performed using a latex-covered AVP (n = 10). All patients had previous nephrostomy with only incomplete clinical improvement. RESULTS: Fourteen of 15 interventions were technically successful. Four of five ureters occluded with a combination of AVP, coils, and tissue adhesive were permanently sealed after a single procedure, whereas one showed slight leakage. After placement of two additional coils 20 days later, permanent occlusion was achieved [mean follow-up 195 (range 30-687) days]. Nine of ten ureters occluded with a latex-covered AVP were completely sealed after a single intervention [mean follow-up 152 (range 10-462) days]. In one case, the latex-cover dislocated during implantation. The AVP alone failed to provide complete dryness. There were no dislocations of the AVP or other major complications. CONCLUSIONS: Transrenal ureteral occlusion using an AVP is a practical, simple, and quick method and can be advantageous in palliative patients suffering from pelvic malignancy.

Urinary tract abnormalities in boys with recurrent urinary tract infections after hypospadias repair.

OBJECTIVE: To examine the development of recurrent urinary tract infections (UTIs) in boys who have undergone hypospadias repair. MATERIALS AND METHODS: We retrospectively reviewed the records of all boys who had recurrent UTIs after primary or redo tubularized incised plate (TIP) or transverse island flap (TVIF) repairs, between 1998 and 2009. Data on age, operating details, postoperative complications and imaging studies were collected. We attempted to identify risk factors for recurrent UTIs after hypospadias repair. RESULTS: During the study period, 43/2249 boys (1.91%) were diagnosed with recurrent UTIs after hypospadias repair. The boys' mean (range) age at repair was 14 (6-24) months and the median (range) follow-up was 6.5 (1.5-11) years. Primary TIP and TVIF were performed in 47% (20/43) and 35% (15/43) of the boys, respectively. Redo surgeries were performed in 18% of the boys (8/43). The initial meatal location was proximal in all TVIF and redo repairs, and in one of the TIP repairs. Postoperative voiding cysto-urethrography, ultrasonography and dimercapto-succinic acid (DMSA) scans were performed in 58% (25/43), 90% (39/43) and 19% (8/43) of the boys, respectively. Abnormalities were noted. Of those boys who underwent a TVIF repair, urethral diverticula were seen in 47% (7/15) and urethral fistulae were also seen in 47% (7/15). Conversely, in those who had a TIP repair, an elevated PVR and vesico-ureteric reflux were more common; they were found in 40% (8/20) and 50% (10/20) of patients, respectively. CONCLUSIONS: The pathophysiology of recurrent UTI is multifactorial, but postoperative complications seem to vary with type of procedure. Recurrent UTIs after hypospadias surgery should prompt a specific assessment for potentially functionally relevant and correctable anatomical abnormalities.

Salvage irrigation-suction in gracilis muscle repair of complex rectovaginal and rectourethral fistulas.

AIM: To evaluate the efficacy of gracilis muscle transposition and postoperative salvage irrigation-suction in the treatment of complex rectovaginal fistulas (RVFs) and rectourethral fistulas (RUFs). METHODS: Between May 2009 and March 2012, 11 female patients with complex RVFs and 8 male patients with RUFs were prospectively enrolled. Gracilis muscle transposition was undertaken in all patients and postoperative wound irrigation-suction was performed in patients with early leakage. Efficacy was assessed in terms of the success rate and surgical complications. SF-36 quality of life (QOL) scores and Wexner fecal incontinence scores were compared before and after surgery. RESULTS: The fistulas healed in 14 patients after gracilis muscle transposition; the initial healing rate was 73.7%. Postoperative leakage occurred and continuous irrigation-suction of wounds was undertaken in 5 patients: 4 healed and 1 failed, and postoperative fecal diversions were performed for the patient whose treatment failed. At a median follow-up of 17 mo, the overall healing rate was 94.7%. Postoperative complications occurred in 4 cases. Significant improvement was observed in the quality outcomes framework scores (P < 0.001) and Wexner fecal incontinence scores (P = 0.002) after the successful healing of complex RVFs or RUFs. There was no significant difference in SF-36 QOL scores between the initial healing group and irrigation-suction-assisted healing group. CONCLUSION: Gracilis muscle transposition and postoperative salvage wound irrigation-suction gained a high success rate in the treatment of complex RVFs and RUFs. QOL and fecal incontinence were significantly improved after the successful healing of RVFs and RUFs.

Chronic epididymitis with scrotal vasocutaneous urinary fistula.

Chronic Epididymitis is a relatively rare problem in boys and is often enigmatic in its etiology. It is often associated with urinary tract abnormalities in infants and prepubertal children. This report describes a rare and unusual case of a chronic epididymitis with acquired scrotal vasocutaneous urinary fistula in an 8-mo-old boy who was found to have a large prostatic utricular cyst and ectopic vas insertion. The authors discuss embryology, pathophysiology, diagnostic dilemma and different treatment options.

Urethral reconstruction in patients suffering from aphallia: a reconstructive challenge.

OBJECTIVE: To document our experience (at a tertiary health care center) of reconstruction of the urethra in 3 male patients suffering from aphallia and congenital urethrorectal fistula as well as their long-term follow-up. METHODS: Extensive single-stage urethroplasty in 3 patients suffering from aphallia was performed. Prior to that, neophallus reconstruction was done in all 3 patients after puberty. In a single stage, we used oral mucosa and pedicled penile skin onlay for anterior urethra reconstruction and groin-based pedicle (Singapore) flap for posterior urethra substitution surgery. The current follow-up is between 2 and 5 years. During the last follow-up, the patients also answered questions from a validated patient-reported outcome measure and quality of life questionnaire. RESULTS: All the 3 patients are voiding well in the standing position with a mean Q(max) of 14 ml/s. None of them has any problems related to the neourethra as per their last follow-up. All 3 patients were satisfied with the surgical procedures related to the aphallia correction and stated that the surgery did not interfere with the quality of their lives. CONCLUSION: Reconstruction of the urethra from pedicled skin flap combined with buccal mucosa graft urethroplasty gives durable and satisfactory long-term results.

Fístula ureterocutánea tras nefrectomía: aportación de dos casos y revisión de la literatura / Ureterocutaneous fistula after nephrectomy: two cases

Las fístulas ureterales se relacionan con la cirugía ginecológica, cirugía digestiva y cirugía urológica reconstructiva del aparato urinario superior. Están descritas fístulas ureterovaginales, ureteroduodenales, ureterocolónicas, ureteropleurales, ureterovasculares, etc. Sin embargo, las fístulas ureterocutáneas del muñón ureteral tras nefrectomía son una entidad muy inusual. Presentamos dos casos así como su resolución mediante cirugía (AU)

The ureteral fistulas are related to the gynecological surgery, digestive surgery and reconstructive urologic surgery of the upper urinary tract. Fistulas are described ureterovaginal, ureteroduodenal, ureterocolonic, ureteropleural, ureterovascular, etc. However, the ureterocutaneous fistulas of the ureteral stump after nephrectomy are a very unusual entity. We report two cases as well as their resolution by means of surgery (AU)

[Pathophysiology of wound healing and current treatment strategies in a urological context]. / Pathophysiologie der Wundheilung und modernes Wundmanagement im urologischen Kontext.

Acute wound healing is a dynamic, interactive process culminating in the closure of a tissue defect. Chronic wounds result when the healing cascade is impaired. Proteases destroy important growth factors and matrix proteins, inflammation is prolonged, and the normal healing process does not take place within the expected time span. Owing to demographic changes the investigation of age-related pathologies, including treatment-resistant wounds, has become increasingly important. The TIME concept (tissue, infection, moisture imbalance, edge of wound) assesses essential elements in the healing process that can be addressed in the treatment of chronic wounds. Moist wound treatment is standard therapy. Definitive research trials on the level of success that can be achieved with different dressings are still needed. New types of treatment should be selected with due consideration for clinical variables, the patient's quality of life and independence, and cost effectiveness.
