Lesión duodeno-ureteral compleja por herida de arma de fuego: diagnóstico y resolución quirúrgica / COMPLEX DUODENAL-URETERAL LESION DUE TO FIREARM INJURY, DIAGNOSIS AND SURGICAL RESOLUTION

Las lesiones traumáticas duodenales son infrecuentes pero producen una tasa de morbi-mortalidad significativa. Se debe tener presente la elevada frecuencia de lesiones asociadas, siendo las de uréter superior las más frecuentes. Masculino de 50 años ingresa por HAF paravertebral derecha. Al ingreso OTE, lucido, vigil, con dolor y defensa abdominal generalizada. En la TC toracobdominal con cte EV y VO se objetiva extravasación de contraste oral a nivel duodenal y en fase excretora renal derecha.Se decide Laparotomía de urgencia objetivando lesión transfixiante de 2da porción de duodeno de < 50% de su circunferencia y sección de uréter derecho proximal. Se realiza rafia en dos planos de duodeno, colocación de pig tail y anastomosis T-T de uréter derecho mas drenaje. Buena evolución postquirúrgica con control tomográfico a las 72 hs sin objetivar fuga. Alta hospitalaria al 6to día. El traumatismo duodenal es una patología rara que se asocia con una tasa considerable de morbimortalidad, su localización retroperitoneal puede hacer que los clásicos signos de peritonismo no estén presentes en el momento de la evaluación, por lo que se recomienda la realización de exámenes clínicos seriados y de estudios complementarios con contraste VO y EV. Las lesiones ureterales asociadas son las más frecuentes. La mayoría tienen una pérdida mínima de tejido, siendo usualmente reparadas mediante desbridación y anastomosis.

Duodenal traumatic injuries are rare but produce a significant morbidity and mortality rate. The high frequency of associated lesions should be kept in mind, with those of the upper ureter being the most frequent. 50-year-old male enters for right paravertebral HAF. At hospital admission, lucid patient and vigil. Thoracoabdominal CT with intravenous and oral contrast show extravasation of oral contrast at the duodenal level and in the right renal excretory phase. Emergency laparotomy is decided by objectifying transfixing lesion of the 2nd portion of the duodenum of <50% of its circumference and proximal right ureter section. Raffia is performed in two planes of the duodenum, placement of pig tail and TT anastomosis of the right ureter plus drainage. Good post-surgical evolution with tomographic control at 72 hours without objectifying leakage. Hospital discharge on the 6th day. Duodenal trauma is a rare pathology that is associated with a considerable morbidity and mortality rate, its retroperitoneal location may make the classic signs of peritonism not present at the time of the evaluation, so clinical exams are recommended series and complementary studies with VO and EV contrast. Associated ureteral lesions are the most frequent, Most have minimal tissue loss, usually repaired by debridement and anastomosis.

Iatrogenic ureteral obstruction during transvaginal ocyte retrieval

ABSTRACT Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can be seen, though rare. In this study, we will present ureteral obstruction that develops secondary to small hematoma, which mimics ovarian cyst torsion or ruptured ovarian cyst.

Management of full-length complete ureteral avulsion

ABSTRACT Introduction Complete ureteral avulsion is one of the most serious complications of ureteroscopy. The aim of this report was to look for a good solution to full-length complete ureteral avulsion. Case presentation A 40-year-old man underwent ureteroscopic management. Full-length complete avulsion of ureter occurred during ureteroscopy. Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis were performed 6 hours after ureteral avulsion. The patient was followed-up during 34 months. Double-J tube was removed at 3 months after operation. Twenty three months after the first operation, the patient developed hydronephrosis because of a new ureter upside stone, then rigid ureteroscopy and holmium laser lithotripsy were used successfully. Conclusion Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis may be a good choice for full-length complete ureteral avulsion.

Robotic repair of vesicovaginal fistula - initial experience

ABSTRACT Objective The most common acquired fistula of the urinary tract is Vesicovaginal fistulae (VVF) (1) posing social stigmata for the patient as well as a surgical challenge for the urologist. Here we present our initial experience with Robotic assisted laparoscopic repair of VVF, its safety and efficacy. Materials and Methods Seven out of eight fistulas were post hysterectomy; five had undergone abdominal while two had laparoscopic hysterectomy while one was due to prolonged labour. Two had associated ureteric injury. All underwent robotic assisted laparoscopic trans abdominal extravesical approach. Three 8 mm ports for robotic arms, one 12 mm port for camera and another 12 mm for assistant were used in a fan shaped manner. All had preoperative ureteric catheter placed. Bladder was closed in two layers and vagina in one layer. Omental flap placed in all cases except two where it was not possible. Drain and per urethral catheter placed in all cases. Double J stents were placed in two cases requiring ureteric implantation additionally. Results The mean age of presentation was 39.25 years (26-47 range) with mean BMI being 26.25 kg/m2 (21-32 range). Mean duration between insult and repair was 9.37 months (3-24 months). Only in single case there was history of previous repair attempt. On cystoscopy four had supratrigonal VVF and four were trigonal with mean size of 13.37 mm (7-20 mm). Mean operative time was 117.5 minutes (90-150). There were no intraoperative/postoperative complications or need for open conversion. Mean haemoglobin drop was 1.4 gm/dL (0.3-2 gm). Drain was removed once 24-48 hours output is negligible. One patient had post-operative urinary leak at 2 weeks which ceased with continuation of catheterisation for another 2 weeks. Catheter was removed after voiding cystourethrogram showed no leak at 2-3 weeks postoperatively. Mean duration of drain was 3.75 days (3-5) and per urethral catheterisation (which was removed after voiding cystourethrography) was 15.75 days (9-28). Mean hospital stay was 6.62 days (4-14). Post-operative bladder capacity was 324.28 cc (280-350) on voiding diary. Follow up ranged from 3-9 months. At 3 months of follow-up, these patients continued to void normally and there was no evidence of recurrence of VVF. Conclusion Robotic repair of VVF is safe and feasible and has additional advantages in the form of precise suturing under 3D vision and certainly a more striking and effective option especially in complex VVF repair associated with ureteric injuries (2).

Identificación de trauma ureteral en un hospital de tercer nivel / Ureteral trauma: report of five cases

Introduction: Ureteral trauma can result from various noxas the most frequent iatrogenic. Additional this, external causes: blunt trauma, sharp weapon and gunshot contributing to the overall incidence. Its early diagnosis although great importance to avoid complications is difficult so it is their suspect is essential when confronted with trauma patients. Case reports: We report five patients aged 15 to 46 years with ureteral trauma. Two patients had gross hematuria, one patient acute abdominal pain and two as hypovolemic shock. The lesions were found mainly to the left ureter and in smaller proportion in right ureter. Four patients the diagnosis was surgical exploration and one case was performed by scans. All were operated, had an uneventful postoperative period and are currently asymptomatic.

Introducción: El trauma de uréter puede ser resultado de diferentes noxas siendo la más frecuente la iatrogénica. Adicional a esto, las causas externas de trauma contuso, las causadas con arma cortopunzante y las realizadas por arma de fuego contribuyen a la incidencia global. Su diagnóstico temprano, aunque de gran importancia para evitar complicaciones, resulta difícil por lo que es primordial su sospecha cuando nos enfrentamos a pacientes politraumatizados. Casos clínicos: Se identificaron 5 casos de trauma ureteral en nuestro hospital desde septiembre de 2012 a agosto de 2013. La mediana de edad fue 24,5 años (15-46 años). Se manifestaron como hematuria macroscópica en dos casos, un caso como dolor abdominal agudo y dos como choque hipovolémico. Estas lesiones se encontraron principalmente localizadas hacia uréter izquierdo y en menor proporción en uréter derecho, todas de tipo penetrante, causadas por arma de fuego. En 4 pacientes el diagnóstico fue por exploración quirúrgica y un caso fue realizado a través de escanografía. Los pacientes fueron intervenidos quirúrgicamente, ninguno presentó complicaciones y se encuentran actualmente asintomáticos.

Broad Ligament Fibroid: A Case Series.

Fibroids are most common benign tumors of the uterus, mostly situated in the body of the uterus. Rarely, they arise from extra-uterine sites with broad ligament fibroids being uncommon. Although by clinical examination and newer imaging modalities, we can easily know about size, number, and origin of these tumors and any anatomical distortion of surrounding vital organs, but some time it is very difficult to differentiate pre-operatively between large broad ligament leiomyomas and ovarian/adnexal pathology specially if cystic degeneration or necrosis is present in leiomyoma. We report four patients with broad ligament fibroids to emphasize the importance of their location, the diagnostic difficulties, and surgical complications they can pose.

Ureteral Cannulation as a Complication of Urethral Catheterization

Urinary catheterization is a common procedure, particularly among patients with neurogenic bladder secondary to spinal cord injury. Urethral catheterization is associated with the well-recognized complications of catheter-associated urinary tract infections and limited genitourinary trauma. Unintentional ureteral cannulation represents a rare complication of urethral catheterization and has been previously described in only eight cases within the literature. We describe two cases of aberrant ureteral cannulation involving two patients with quadriplegia. These cases along with prior reports identify the spastic, insensate bladder and altered pelvic sensorium found in upper motor neuron syndromes as major risk factors for ureteral cannulation with a urinary catheter.

Sustitución ureteral bilateral con asa ileal / Bilateral ileal ureteral replacement

Introduction: Ureteral replacement by a loop of defunctionalized ileum was described more than 2 centuries ago and continues to be a therapeutic option at present. This series describes the technique of bilateral ureteral replacement with ileum. Aim: To report 4 cases of bilateral ileal ureteral replacement performed at our institution, its indications, the surgical technique, complications, and a review of the literature. Material and Method: We report 4 cases of extensive bilateral ureteral injury of different etiologies, whose treatment with curative intent was to replace the damaged ureter with a isoperistaltic small bowel segment. Results: The surgical technique used was standard in all cases. There were no intraoperative complications and only one patient had hyperchloremic acidosis. No patient has shown loss of renal function in the long-term follow up. Conclusion: Is an effective therapeutic, safe and reproducible technique to replacement of major bilateral ureteral injuries, independent of the original cause.

Introducción: La sustitución ureteral por un asa de íleon desfuncionalizada fue descrita hace más de 2 siglos y continúa siendo una alternativa terapéutica en la actualidad. Esta serie describe la técnica de sustitución ureteral bilateral con íleon. Objetivo: Presentar 4 casos de sustitución ureteral ileal bilateral realizados en nuestro centro, indicaciones de la técnica quirúrgica, complicaciones y revisión de la literatura. Material y Método: Presentamos 4 casos de lesión ureteral bilateral extensa, de etiologías diferentes, cuyo tratamiento con intención curativa fue la sustitución de la lesión ureteral por un segmento intestinal isoperis-táltico. Resultados: La técnica quirúrgica empleada fue estándar en todos los casos. No hubo complicaciones intraoperatorias, y sólo una paciente presentó descompensación metabólica por acidosis hiperclorémica. En ningún paciente se ha demostrado pérdida en la función renal. Conclusión: El segmento intestinal de íleon desfuncionalizado es una alternativa terapéutica eficaz, segura y reproducible, para el reemplazo de importantes lesiones ureterales bilaterales, independiente de la causa original.

Reemplazo ureteral con apéndice cecal / Ureteral replacement with cecal appendix

We report two cases with ureteral lesions. A 34 years male with a residual retroperitoneal mass caused by a testicular cancer, that persisted after chemotherapy. During the surgical excision of the mass, the involvement of the right ureter was discovered. A 43 years old female with a left ureteral lesion secondary to radiation therapy and with a non-functioning contralateral kidney. In both cases a ureteral replacement with the cecal appendix was performed, without surgical complications. After five years of follow up, the urinary tract of the male patient is normal. The female patient required an endoscopic incision of the connection between the appendix and the urinary bladder, eight years after the surgical procedure. Three years after the endoscopic procedure the repaired urinary tract is in good conditions.

Objetivo: Presentar dos casos de reemplazo ureteral con apéndice cecal y revisar la literatura relacionada al tema. Material y Método: Presentamos dos casos de lesión ureteral. Un paciente de 34 años con masa retroperitoneal residual post quimioterapia englobando el uréter derecho, secundaria a un tumor testicular, y una paciente de 43 años monorrena funcional con lesión ureteral izquierda actínica. Resultados: En ambos casos se realizó un reemplazo ureteral, derecho e izquierdo, sin complicaciones intraoperatorias. El seguimiento alejado a 5 y 11 años muestra indemnidad de la vía urinaria. Conclusión: Estos 2 casos, con seguimiento prolongado, apoyan la factibilidad del uso del apéndice cecal como variante para el reemplazo ureteral en lesiones extensas.

Ureteroscopy in patients with coagulopathies is associated with lower stone-free rate and increased risk of clinically significant hematuria

PURPOSE: Patients with coagulopathy are at increased risk of peri-operative hemorrhage. The aim of the present study was to compare ureteroscopy (URS) in these high risk patients to those with normal bleeding profile. MATERIALS AND METHODS: Twelve patients with coagulopathies (Group I) undergoing 17 URS were included in the study [3 for biopsy of ureteral lesions and 9 for Holmium Laser Lithotripsy (HLL)]. A patient had Child B (MELD 11) cirrhosis, 6 patients were on warfarin, 3 patients on ASA, 1 patient on ASA and clopidogrel, and the last patient was on heparin. URS in Group I was performed without correction of coagulopathy. Group II consisted of 32 patients with normal bleeding profile who underwent 34 URS concurrently. RESULTS: Group I included 4 ureteral biopsies in 3 patients with suspicious ureteral lesions and 13 URS for HLL in 9 patients with nephrolithiasis. There were no significant differences between the two groups in terms of patient age, sex, percent of renal stones, median operative and fluoroscopy times. When compared with Group II, Group I had significantly larger median stone size (9.2 vs. 14.0 mm, p = 0.01) and significantly lower stone-free rate after first URS (94.1% vs. 69.2%, p = 0.04). However, after second URS, stone-free rates were comparable in both groups (92.3% vs. 100%, p = 0.9). Two (16.7%) patients with coagulopathy were readmitted due to gross hematuria. There were no post-operative complications in Group II. CONCLUSIONS: Although URS in selected patients with coagulopathies is safe, it is associated with significantly lower stone-free rates and higher readmissions due to gross hematuria.

Extravasación urinaria postraumatismo abdominal cerrado: ¿es posible un diagnóstico precoz?: informe de dos casos / Urinary extravasation post blunt abdominal trauma: is it possible an early diagnosis?: report of two cases

La lesión de la vía urinaria superior con extravasación urinaria ocasionada por un traumatismo abdominal cerrado es infrecuente y, a menudo, no reconocida en una evaluación inicial.Un diagnóstico tardío de esta lesión aumenta significativamente la morbilidad. Se presentan dos casos, uno con avulsión de uréter superior derecho y el otro con laceración parenquimatosay de pelvis renal derecha con diagnóstico tardío y complicacionesgraves postraumatismo abdominal cerrado directo. El conocimiento del mecanismo del traumatismo y la evaluación de signos y síntomas locales son datos de importancia parasospechar una lesión pieloureteral, independientemente de la gravedad del traumatismo. La ausencia de hematuria inicial no es infrecuente y su presencia y grado no guarda relación con lagravedad de la lesión. Una tomografía computada abdominal con contraste endovenoso, evaluada en fase excretora tardía, permite la identificación precoz de una extravasación de orina.

An injury to the upper urinary tract with urinary extravasation caused by blunt abdominal trauma is uncommon and often unrecognized in an initial evaluation. A late diagnosis of this injury significantly increases morbidity. Two cases are discussed, one with avulsion of right upper ureter and the other one with parenchymal and right renal pelvis laceration with delayed diagnosis and severe complications subsequent to a direct blunt abdominal trauma. Knowledge of the mechanismof trauma and the assessment of local signs and symptoms are important data for suspecting ureteropelvic injury regardless of the trauma severity. The absence of initial hematuria is notuncommon and their presence and degree is unrelated to the severity of the injury. An abdominal computed tomography with IV contrast evaluated in delayed excretory phase allows an early detection of extravasation of urine.

Reparación de lesiones ureterales distales con el Flap de Boari laparoscópico: experiencia en 13 casos / Distal ureteral reconstruction using laparoscopic Boari Flap: experience in 13 cases

Introducción: El flap de pared vesical tubularizado para el reemplazo del uréter distal (Boari) constituye una excelente alternativa para la reparación quirúrgica de diferentes patologías que involucran la pérdida de parte del uréter distal, facilitando una reconstrucción relativamente simple y sin tensión en las líneas de sutura. En el año 2000 comenzamos una experiencia realizando esta técnica por vía laparoscópica, que detallamos a continuación. Material y Método: Se consideraron candidatos para la técnica a pacientes con patología que condicionara estenosis del uréter distal, con vejiga de capacidad adecuada y con función renal ipsilateral normal. Se incluyeron además pacientes con lesión ureteral en el curso de laparoscopia ginecológica. La técnica es básicamente la misma que se utiliza en cirugía abierta, que incluye la resección del uréter patológico y la construcción de un flap de pared vesical que se tubulariza y se anastomosa sin tensión al cabo distal del uréter remanente. Resultados: En un período de 6 años se operaron 13 pacientes con una edad promedio de 39,5 años (rango de 9 a 71), 7 mujeres y 6 hombres. En 9 casos el diagnóstico previo era estenosis por enfermedad benigna, entre los cuales hubo 2 casos de neoimplante previo con estenosis posterior y dos casos de litiasis ureteral. En 2 casos el diagnóstico fue compatible con lesión actínica del uréter luego de radioterapia por cáncer cervicouterino. En 2 casos el diagnóstico fue tumor ureteral, uno de ellos tumor de células transicionales superficial y de bajo grado y en el otro un papiloma invertido. Hubo dos pacientes operadas por lesión por cirugía ginecológica, una ligadura de uréter inadvertida y una sección de uréter que se reparó en forma inmediata. Hubo un caso de estenosis ureteral por endometriosis. Todos los pacientes han sido controlados con pielografía de eliminación. Hasta el momento no ha habido pérdida de unidades renales ni necesidad de reoperación en ningún paciente...

Background: Tubularized bladder wall flap (Boari flap) is an excellent surgical replacement technique for diseases involving the distal ureter. It allows a simple reconstruction and voids tension in suture lines. Since 2000 we are performing this operation by laparoscopy. Aim: To report the experience with laparoscopic Boari Flap. Material and methods: Retrospective review of patients subjected to a laparoscopic Boari flap. Patients with a distal ureter stricture, with a urinary bladder of adequate capacity and with a normal ipsilateral renal function, were considered eligible for the operation. Patients with ureteral lesions occurring during gynecologic laparoscopy were also included. The technique consists in the excision of the diseased ureter and construction of a bladder wall flap that is tubularized and anastomosed to the distal part of the remaining ureter. Results: Thirteen patients aged 9 to 71 years, (seven females) were operated in a lapse of six years. Nine had a benign ureteral stricture. Among these, two had a previous neo-implant with subsequent stenosis, two had ureteral stones, two had a radiation injury secondary to radiotherapy for cervical cancer, two had ureteral tumors (a transitional cell tumor and an inverted papilloma), two patients had iatrogenic ureteral lesions during gynecological surgery (an inadvertent ureteral ligation and an ureteral sectioning that was repaired and two patients had ureteral stenosis secondary to endometriosis. All patients were followed with intravenous pyelograms. After a mean follow up of 25 months, no patient has lost a kidney or required a new operation. Conclusions: Boari flap is an excellent laparoscopic alternative to replace the distal ureter.

[Lower urinary trauma complicating gyneacological and obstetrical surgery]

The trauma of the lower urinary tract in gynecologic and obstetrics surgery is rare. Discover the circumstances of their happening, their symptoms, and their methods of diagnostic and their treatment. Authors report 24 cases observed over a 12 years period. These lesions consisted on 20 bladder lesions and 4 ureteric lesions. The frequency of these urological complications was 0.21% among the 12000 surgical operations performed between 1992 and 2003. The most causal operation was caesarean and abdominal hysterectomy. Urinary trauma was more frequent in patients with history of abdominal surgery. Post operative course was uneventful in most cases. Trauma of the lower urinary tract in gynecologic and obstetrics surgery is rare but their ignorance may seriously affect the functional urinary prognostics

Percutaneous Management of Ureteral Injuries that are Diagnosed Late After Cesarean Section

OBJECTIVE: We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). MATERIALS AND METHODS: Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for making the diagnosis was 21 +/- 50.1 days. The injury site was the distal ureter in all cases (the left ureter: 13, the right ureter: 7 and bilateral: 2). Fifteen complete ureteral obstructions were detected in 13 cases. Ureteral leakage due to partial (n = 4) or complete (n = 3) rupture was noted in seven cases. Two cases had ureterovaginal fistula. All the cases were initially confirmed with antegrade pyelography and afterwards they underwent percutaneous nephrostomy. Balloon dilatation was needed in three cases. Antegrade DJ stents were placed in 10 cases, including the three cases with balloon dilatation. Repetititon of percutaneous nephrostomy with balloon dilatation and DJ stent placement was needed in one case with complete obstruction. All the cases were followed-up with US in their first week and then monthly thereafter for up to two years. RESULTS: Eighteen ureters (75%) were managed by percutaneous procedures alone. A total of six ureter injuries had to undergo surgery (25%). CONCLUSION: Percutaneous management is a good alternative for the treatment of post-CS ureteral injuries that are diagnosed late after CS. Percutaneous management is at least preparatory for a quarter of the cases where surgery is unavoidable.

Penetrating ureteral trauma

OBJECTIVE: The purpose of this series is to report our experience in managing ureteral trauma, focusing on the importance of early diagnosis, correct treatment, and the impact of associated injuries on the management and morbid-mortality. MATERIALS AND METHODS: From January 1994 to December 2002, 1487 laparotomies for abdominal trauma were performed and 20 patients with ureteral lesions were identified, all of them secondary to penetrating injury. Medical charts were analyzed as well as information about trauma mechanisms, diagnostic routine, treatment and outcome. RESULTS: All patients were men. Mean age was 27 years. The mechanisms of injury were gunshot wounds in 18 cases (90 percent) and stab wounds in two (10 percent). All penetrating abdominal injuries had primary indication of laparotomy, and neither excretory urography nor computed tomography were used in any case before surgery. The diagnosis of ureteric injury was made intra-operatively in 17 cases (85 percent). Two ureteral injuries (10 percent) were initially missed. All patients had associated injuries. The treatment was dictated by the location, extension and time necessary to identify the injury. The overall incidence of complications was 55 percent. The presence of shock on admission, delayed diagnosis, Abdominal Trauma Index > 25, Injury Severity Score > 25 and colon injuries were associated to a high complication rate, however, there was no statistically significant difference. There were no mortalities in this group. CONCLUSIONS: A high index of suspicion is required for diagnosis of ureteral injuries. A thorough exploration of all retroperitoneal hematoma after penetrating trauma should be an accurate method of diagnosis; even though it failed in 10 percent of our cases.

Lesiones ureterales en la cirugía ginecológica / Ureteral lesions in gynecological surgery

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. Las otras soluciones fueron cateterismo, anastomosis término terminal y uretero anastomosis con conducto ileal en una paciente irradiada y con cistitis actínica. Los resultados fueron buenos con todas las medidas usadas, excepto la exclusión de un riñón en la Boari Cassatti bilateral y 2 leves ureterectasias, sin síntomas, al año de control, también con la técnica de reimplante con colgajo vesical.
