Bilateral obstructive uropathy secondary to giant periureteral diverticulum.

Bladder diverticula are herniations of the mucosa through the fibers of the bladder muscle connected by necks of variable amplitude. They are often asymptomatic, although they may lead to complications that require a surgical therapeutic approach. We report the case of a patient with bilateral obstructive uropathy secondary to a giant periureteral diverticulum that was treated by diverticulectomy and reimplantation of the left ureter in the bladder.

Key areas in the learning curve for robotic urological surgery: a Spanish multicentre survey.

BACKGROUND: The number of robotic-assisted procedures offered in Spain is rapidly increasing despite a lack of consensus criteria for training and credentialling. OBJECTIVE: This national multicentre study was designed to analyze the different areas of the robotic urological surgery learning curve. MATERIAL AND METHODS: A questionnaire was sent to all 13 urology units in Spain with an active robotics programme requesting information on training and problems encountered. RESULTS: In most centres (n = 11, 84.6%), training programmes were animal-based; cadavers were used at only 2 (15.4%). Proctoring in initial procedures was practiced by 12 groups (92.3%). When initiating the robotics programme, the console was shared at 8 units (61.5%). Prior experience in open and/or laparoscopic surgery was reported by 10 of the groups (76.9%), and experience in open surgery only by 2 (15.4%) or robotic surgery alone by 1 (7.7%). The procedure with which the robotics programme was started in all 13 participating units was radical prostatectomy. The number of cases needed to complete the learning curve for this procedure was 20-25 cases according to 8 (61.5%) surgery teams. CONCLUSIONS: Up until March 26, 2010, 1,692 operations, mostly radical prostatectomies, were conducted using the da Vinci robot in our country.

Surgical repair and analysis of penile fracture complications.

BACKGROUND: The objective of this study is to describe and analyze the experience over a period of 10 years at our center through a retrospective study of a series of diagnosed and treated cases of penile fracture. MATERIAL AND METHODS: From 2005 to 2009 the Urology Department of the Hospital Clínico San Carlos of Madrid carried out a retrospective case study of a total of 15 cases of penile fracture. The diagnosis was reached through physical exploration of the patient aided by a penile ultrasound; the immediate treatment performed on the patients was emergency surgical repair. RESULTS: From the total in the series (n = 15), only 1 case was associated with a complete urethral fracture (6.6%). Surgical repair was performed in all cases; the average hospital stay was 2.6 days (range 1-5), and the most frequent long-term complication was erectile dysfunction in 3 of 15 cases (20%). CONCLUSIONS: A penis fracture diagnosis is mostly clinical; complementary tests, such as ultrasound, are helpful but not definitive. Surgical treatment consists of an incision that allows adequate exposure of the corpora cavernosa and urethra to repair the suspected lesions found upon diagnosis. Ambulatory follow-up is essential to diagnose and treat possible complications.

Long-term outcomes after robotic sacrocolpopexy in pelvic organ prolapse: prospective analysis.

OBJECTIVE: To evaluate the feasibility and long-term outcomes of our initial series of robot-assisted laparoscopic sacrocolpopexy. METHODS: We conducted a prospective analysis of our series of robotic sacrocolpopexy. INCLUSION CRITERIA: patients with grades III and IV cystocele and or other symptomatic pelvic organ prolapse. We performed a transperitoneal four-trocar technique with the Da Vinci robotic system using two polypropylene meshes for fixation to the sacral promontory. The primary outcome was recurrence; secondary outcomes included operating room time, blood loss, conversion to open surgery, complications and length of stay. RESULTS: 31 consecutive procedures were included. Mean patient age was 65.2 (50-81) years. Mean operating room time was 186 (150-230) min. We converted 1 case to laparoscopy (3.2%). There were two major complications (1 acute myocardial infarction and 1 reoperation for excess tension with syncopes), two minor complications (1 wound infection and 1 ileus) and no recurrences at a mean follow-up of 24.5 (16-33) months. CONCLUSIONS: Robotic sacrocolpopexy could possibly improve with experience after overcoming the learning curve. There is no doubt it is a reproducible technique, but its safety and efficacy still need to be proven. Our initial series demonstrated good outcomes and no recurrences at 24.5 months of follow-up.

Progression of null or mild lower urinary tract symptoms indicative of benign prostatic hyperplasia after 2 years of follow-up in non-treated men aged 40 years or older.

OBJECTIVES: After screening men aged 40 years or older for lower urinary tract symptoms (LUTS) indicative of benign prostatic hyperplasia over the years 1999 to 2000, non-treated men with an initial International Prostate Symptoms Score (I-PSS) equal to or lower than 2 were assessed 2 years later for symptom progression. METHODS: A cross-sectional study was conducted in 1999 on 1804 men aged 40 years or older who were living in Madrid. In a telephone interview sociodemographic information was requested and LUTS assessed using the I-PSS. Of 975 men with no LUTS or lower than 2 in this baseline survey, 463 were re-interviewed in 2001. The dependent variable was the change from null/mild to moderate/severe LUTS produced over 2 years. RESULTS: Over the 2-year period, the mean increase in I-PSS score was 2.20 (95% CI, 1.89-2.51). The cumulative incidence of progression from asymptomatic/mild to moderate/severe disease was 9.94% (95% CI, 7.53-13.00). In the multivariate logistic regression model men who lived in a rural setting (OR, 2.70; P = .01) and armed forces, qualified agriculture and fishing workers (OR, 4.11; P = .05) were independently associated with progression. Age and alcohol intake were also found to interact; intake of 0.01-25.99 g/day in men older than 50 years (OR, 0.28; P = .008) was related to a lower frequency of progression than the same alcohol intake in men younger than 50 years (OR, 2.03; P = .380). CONCLUSIONS: After the 2-year period, the incidence of symptom progression was 10% in men aged 40 years or older with an initial I-PSS equal to or lower than 2.

[Correlation of bladder thickness on ultrasound with clinical and urodynamic data in symptomatic benign prostatic hyperplasia]. / Correlación del grosor ecográfico vesical con los datos clínicos y urodinámicos en la hiperplasia benigna de próstata (HBP) sintomática.

OBJECTIVES: Our objective is to verify the diagnostic usefulness of ultrasound measurement of the thickness of the bladder wall, and the correlation with clinical/ urodynamic findings in patients with symptomatic BPH. METHODS: We performed a prospective cross-sectional study (cross-sectional study '') in a series of 74 males (age chi= 72.4 S = 7.1 (56-84 years) with symptomatic BPH. Patients completed the IPSS and determined the plasma level of PSAt (ng / ml). Before performing the urodynamic study, was determined by transabdominal ultrasonography (3.5 MHz transducer): prostate volume (cc) by the ellipsoid formula, and bladder wall thickness (mm) measured on the anterior bladder wall. Statistical analysis was performed using ANOVA, the Pearson correlation, and ROC curve. RESULTS: It was a significant correlation of the sonographic thickness of the bladder wall with the IPSS (p = 0001, r = 0.38) (parameter in turn highly correlated with prostate volume and PSA (p = 0.01, r = 0.62)), as well as the detrusor hyperactivity (p = 0.03, r =0.21), cut off ROC curve: 3.85 mm. Instead, it was not shown a significant correlation between the sonographic thickness of the bladder wall and the urodynamic diagnosis of obstruction (Abrams and number Griffths p = 0223, r = 0.14) or the detrusor contractile power, measured in power at peak flow (Pw) (p = 0642 r =- 0.55), nor with age (p = 0303, r = 0.12). Neither correlation was observed with other non-invasive urodynamic measures (the maximum urinary flow flowmetry (p = 0318, r = 0.12) and percentage postmicturition residual (p = 0696, r = 0.05)). CONCLUSIONS: The ultrasound measurement of bladder wall thickness, although it has not proved useful ness in our series in the diagnosis of the voiding phase (lower urinary tract obstruction and detrusor contractility impairment), on the contrary it can be introduced as a diagnostic technique for non-invasive studies in the alterations of the filling phase, in the form of detrusor hyperactivity in also patients with symptomatic BPH, and present a significant correlation with prostate growth.

Bladder diverticulum robotic surgery: systematic review of case reports.

INTRODUCTION: We report one case of robot-assisted transperitoneal bladder diverticulectomy and perform a systematic review of published experience. PATIENT AND METHODS: Our patient was a 64-year-old male with a history of lower urinary tract symptoms secondary to benign prostatic enlargement for 6 years with recurrent urinary tract infection. Ultrasound and voiding cystourethrogram showed a 7-cm diverticulum in the posterior bladder wall. After bibliographic search in PubMed/Medline, 17 articles on laparoscopic diverticulectomy and 8 on robotic diverticulectomy were selected. RESULTS: Transperitoneal robot-assisted diverticulectomy was performed with the Da Vinci 4-arm system (Intuitive Surgical Inc., Sunnyvale, Calif., USA) without perioperative complications. Operative time was 80 min and blood loss less than 100 ml. Transurethral prostatic resection combined with Greenlight laser vaporization was performed in a second step. CONCLUSIONS: Robot-assisted bladder diverticulectomy is safe, effective, reproducible and minimally invasive. Cost is higher than for laparoscopic surgery and access to this technology is limited.

[High dynamic risk cystoceles]. / Cistoceles de alto riesgo urodinamico.

OBJECTIVES: To assess the bladder compliance in a series of cystoceles referred for urodynamic study. METHODS: Retrospective study of a series of patients with cystocele undergoing medical history, videurodynamic study, pelvic MRI and lower urinary tract, urological ultrasound and cystoscopy. We Excluded cases with neurogenic dysfunction and urinary infection. The terminology followed the criteria of the ICS, if not specified otherwise. The series includes 3333 cases of cystocele 616 of which are grade III cystocele. There were 3 cases with low bladder compliance; this is 0.0009% of total (1:1000) and 0.5% of grade III cystocele (1:200) RESULTS: All cases of cystocele whith low compliance were associated with feeling of a bulk in the vagina and functional symptoms of lower urinary tract(LUTS). No urinary incontinence was related to cough. These patients also showed urodynamic alterations in the voiding phase, type hypo / acontractile detrusor and postvoid residual. The patients were subjected to various techniques of abdominal and transvaginal cystocele repair (with preventive anti-incontinence surgery), getting a vagina bulk disappearance, improvement of symptoms of lower urinary tract function, normalization of bladder compliance and detrusor contractility, with elimination of the postvoid residual. CONCLUSIONS: Although they are not frequent, high-risk cystoceles should be discarded in high-grade cystocele that apart from low bladder accommodation, have a hipo/acontractile detrusor and postvoid residual. Surgical correction of cystocele not only reduces the bulk and LUTS, but normalizes urodynamic alterations.

[Multidisciplinary development of robotic surgery in a University Tertiary Hospital: Organization and outcomes]. / Desarrollo multidisciplinario de la cirugía robótica en un hospital universitario de tercer nivel: organización y resultados.

BACKGROUND: Da Vinci system (Intuitive Surgical) is a surgical telemanipulator providing many technical advantages over conventional laparoscopic approach (3-D vision, ergonomics, highly precise movements, endowrist instrumentation...) and it is currently applied to several specialties throughout the world since 2000. The first Spanish public hospital incorporating this robotic technology was Hospital Clinico San Carlos (HCSC) in Madrid, in July 2006. We present the multidisciplinary organization and clinical, research and training outcomes of the Robotic Surgery Plan developed in the HCSC. MATERIAL AND METHODS: Starting from joint management and joint scrub nurses team, General and Digestive Surgery, Urology and Gynaecology Departments were progressively incorporated into the Robotic Surgery Plan, with several procedures increasing in complexity. A number of intra and extra-hospital teaching and information activities were planned to report on the Robotic Surgery Plan. RESULTS: Between July 2006 and July 2008, 306 patients were operated on: 169 by General Surgery, 107 by Urology and 30 by Gynaecology teams. The outcomes showed feasibility and a short learning curve. The educational plan included residents and staff interested in robotic technology application. CONCLUSION: The structured and gradual incorporation of robotic surgery throughout the PCR-HCSC has made it easier to learn, to share designed infrastructure, to coordinate information activities and multidisciplinary collaboration. This preliminary experience has shown the efficiency of an adequate organization and motivated team.

[Prognostic factors for survival in patients with transitional bladder cancer treated with radical cystectomy]. / Factores pronósticos en la supervivencia de los pacientes con carcinoma transicional de vejiga tratados con cistectomía radical.

PURPOSE: To recognize clinical and pathological variables that influence in bladder cancer specific mortality in patients with transitional bladder cancer treated with radical cystectomy. MATERIAL AND METHOD: Retrospective analysis of 333 patients with transitional bladder cancer treated with radical cystectomy. Variables included during pre-cystectomy, peri-cystectomy and post-cystectomy period were analyzed. Four groups were defined based on pathological state: a) Organ-confine bladder cancer without lymph node metastasis (pT0-2, pN0); b) Extravesical desease without lymph node metastasis (pT3-4, pN0); c) Bladder cancer with lymph node metastasis (pT0-4, pN+); d) No data of lymph node affection (pT0-4, pNx). Univariate analysis and two models of multivariate analysis were performed including the risk group as a variable in one the latest. RESULTS: Mean follow up was 52.6 +/- 51 (2-221) months with a median of 31 months. Pathological state pT0 was observed in 7.2% of the patients, 12% were pT1, 26.7% pT2, 34.5% pT3 and 10.5% pT4. Lymph node metastasis was detected in 20.7% of the patients. Lymph node metastasis increased according to pathological state rises. Five and 10 years specific survival was 57% and 54% respectively. CONCLUSIONS: Local pathological state, lymph node status and risk groups were independent predictive factors for bladder cancer specific survival. Risk group association is a reliable method to predict bladder cancer specific survival and to identify the suitable patient group to get benefit from adjuvant therapy.

[Prevalence of lower urinary tract symptoms related with benign prostatic hyperplasia. Study of 1804 men aged 40 or older in Madrid]. / Prevalencia de síntomas del tracto urinario inferior relacionados con la hiperplasia benigna de próstata. Estudio de 1804 hombres de 40 años o más residentes en Madrid durante 1999-2000.

INTRODUCTION: Lower urinary tract symptoms (LUTS) related with benign prostatic hyperplasia (BPH) are present nowadays in approximately 20 to 30% of the Spanish male population from the age of 50 onwards. The purpose of this study was to assess clinical and epidemiological characteristics of patients with LUTS. METHODS: A cross-sectional study was performed, between 1999 and 2000, among 1,804 men aged 40 or older who were living in Madrid. Subjects were interviewed by telephone; socio-demographic information was requested and the presence of LUTS was assessed using the International Prostate Symptoms Score. Informed consent was requested, Association between qualitative variables was evaluated by chi2 or Fisher's test. A logistic regression model was performed to control confusion. RESULTS: Prevalence of moderate/severe LUTS was 16.6% (95%CI: 14.8-18.3). Nearly 90% of the subjects consumed olive oil, 71.5% alcohol, 63.1% did not smoke and 96.9% did not consume drugs. A 27.7% of the subjects had hypertension and 8.8% referred diabetes. Men aged 70 or older had a threefold increased frequency of serious symptoms compared to younger men (OR: 3.31; 95%CI: 2.10-5.22). Low level of studies increased this frequency by a factor of 2.2 (95%CI: 1.42-3.46) and men who consumed only seed oil had twice more serious symptoms than those who consumed olive oil (OR: 1.86; 95%CI: 0.98-3.55). CONCLUSIONS: Family history of urological diseases, age, low level of studies, hypertension, diabetes and seed oil consumption were independently associated with more serious symptoms, while medium alcohol consumption and mild smoking habit were associated with slighter symptoms.

[Urodynamic evaluation in prostate cancer patients with urinary incontinence]. / Valoración urodinámica en el cáncer de próstata con incontinencia.

OBJECTIVES: Update on the urodynamic evaluation in patients with prostate cancer who have incontinence. METHODS: To review the urodynamic studies in prostate cancer patients who suffer from incontinence, irrespective of the treatment carried out. RESULTS: The largest amount of information on urodynamic studies in patients with prostate cancer and incontinence was found in those with post-prostatectomy incontinence. There is much more limited work on irradiated patients, and after medical treatment. CONCLUSION: The urodynamic study in these patients may help clarify the etiopathogenic mechanisms of incontinence, try to predict risk factors before treatment and help the therapeutic decision making. Further studies are needed, especially in patients undergoing radiotherapy, to further assess the mechanisms involved in lower urinary tract abnormalities that occur in these patients.

[Da Vinci robot assisted radical prostatectomy: one year experience at the Hospital Clínico San Carlos]. / Prostatectomía radical asistida por robot Da Vinci: un año de experiencia en el Hospital Clínico San Carlos.

OBJECTIVES: Hospital Clínico San Carlos in Madrid is the first Spanish public centre using the latest surgical technology: the Da Vinci robot. First operation was carried out in our department in October 9th 2006. Since then, numerous changes have happened which enabled us to overcome difficulties, to complete the learning curve. METHODS: Between October 9th 2006 and November 30th 2007 we performed 30 radical prostatectomies with the Da Vinci robot. Mean patient age was 63 years (47-70 years) with an ASA (American society of anesthesia) risk below III in all cases, a Gleason score between 2 and 8 and a PSA < or = 15 (3.5-15). Mean prostatic volume measured by transrectal ultrasound was 36 cc (16-90 cc). RESULTS/CONCLUSIONS: Six trocars and a 15 mm Hg pneumoperitoneum were employed. Mean operative room occupation time was 5.9 hours (4-14 hours). Two cases were converted to open surgery and one to laparoscopy. No major intraoperative complications have happened. In the immediate post-operative period, 2 patients presented plexopathy and arthralgia, 1 infection at the site of one trocar, and 2 haematomas at the site of trocar insertion. Sixteen patients required transfusion (mean 1 red blood cells unit (0-4)). Bladder catheter was retrieved between 5th and 21st post-operative days (mean 11 days). Regarding continence: 10 patients were completely continent or present mild incontinence (0-1 pad) and 5 had moderate incontinence (2-5 pads). Three patients preserve sexual potency, the rest show different grades of dysfunction.

[Video urodynamic update of the vesicoureteral reflux classification in children]. / Actualización videourodinámica de la clasificación del reflujo vesicoureteral en el niño.

OBJECTIVES: To update the classification of vesicoureteral reflux in children. METHODS: Videourodynamics. RESULTS: We categorize the different types of vesicoureteral reflux in children. CONCLUSIONS: The usefulness of the classification is demonstrated, with the introduction of some modifications necessary for its continuous updating.

[The usefulness of laser in the treatment of urethral stenosis]. / Utilidad del láser en el tratamiento de las estenosis uretrales.

INTRODUCTION: Optical urethrotomy was introduced by Sachse in 1973 and it has a registered long-term recurrence rate of 75-80%. This stimulated the search for new therapies with less recurrences. Several types of laser were tried: Nd:YAG, KTP, Argon, Ho:YAG, diode,... Since the end of the '70s various types of laser are being used for the treatment of ureteral stenosis. OBJECTIVES: To describe the usefulness of the laser energy in the treatment of ureteral stenosis, mainly recurrent stenosis and to analyze the current experience with various types of laser (diode, nd:yag, holmium, argon,...) METHODS: We performed the systematic review of the bibliography, based on a medline search, and a detailed analysis of the selected articles. CONCLUSIONS: 1) The use of laser in the treatment of urethral stenosis is on the a valid, effective, and safe alternative option to optical urethrotomy, at least in the mid term; nevertheless, it has not demonstrated to date being better than that. 2) The election of treatment is surgeon dependent and, and no single technique has demonstrated to be clearly better than the others. 3) Prospective long-term studies with larger numbers of patients and longer follow-up are necessary. 4) Laser technology is extensive and it is not available in all centers.

[Urodynamic test with self reduction of the cystocele in the diagnosis of lower urinary tract obstruction]. / Test urodinámico de autoreducción del cistocele en el diagnóstico de obstrucción del tracto urinario inferior.

OBJECTIVES: The association of cystocele and urodynamic lower urinary tract obstruction is frequent, occasionally not being possible to rule out intrinsic obstruction of bladder neck and urethra. With the aim to confirm the obstructive character of the cystocele we performed at test consisting in manual reduction of the cystocele by the patient herself, to check if by this simple manoeuvre the urodynamic parameters of obstruction disappear or diminish. METHODS: 24 patients consulting for sensation of vaginal bulge, with a mean age of 66 years, participated in the study. The initial diagnosis of lower urinary tract obstruction and cystocele was obtained after video-urodynamic tests. The urodynamic test with self reduction of the cystocele was based on cystomanometry and voiding pressure-flow tests. The parameters of the study included presence, amplitude and bladder capacity during detrusor involuntary contractions in the cystomanometry; in the voiding pressure/flow test the parameters of the study were the URA as a urethra resistance parameter, the type of obstruction with the Chess classification, and Wmax and W80-W20 as parameters of detrusor contractility. RESULTS: A higher frequency of severe (58.3%) than moderate (41.6%) cystocele was demonstrated. No significant relation with age was demonstrated. The URA significantly diminished (p<0.01) with self reduction: from a median value of 30.5 before to 15.5 H2O cm after reduction. Although it was observed in all grades of cystocele, this reduction was greater in the severe ones. The most frequent type of obstruction was the constrictive (62.5%), over compressive (4.2%), mixed (12.5%) and unobstructed (4.2%). The constrictive obstruction significantly disappeared or diminished after reduction (p < 0.05) to a 45.8% of the cases, the compressive to 0%, the mixed to 4.2% and the nonobstructive to 50%. No significant relationship between these data and grade of cystocele was demonstrated. On the other hand, no significant differences were demonstrated with cystocele self reduction in the other urodynamic parameters (detrusor hyperactivity and contractility, Wmax and W80-W20), neither in their relationship with the grade of cystocele. CONCLUSIONS: This test could be very useful in the diagnosis of lower urinary tract obstruction for its validity and significance, apart from being an easy to perform and reproducible test.

[Robotic assisted laparoscopic colposacropexy in the treatment of pelvic organ prolapse]. / Colposacropexia laparoscópica asistida por robot como tratamiento del prolapso urogenital.

Laparoscopic colposacropexy has become a substitute for open surgery in the treatment of pelvic organ prolapse. In the same way, robotic assisted surgery is a new step in the evolution of the procedure. In this paper we intend to show our surgical technique and preliminary results. From November 2006 to date, 10 patients have undergone this procedure at the Hospital Clinico San Carlos. The main indication for the operation was existence of symptomatic pelvic prolapse. Both patients with or without hysterectomy have been operated, without making significant differences between them. Preoperative evaluation workout included: cystogram, urinary tract ultrasound and urodynamics in all cases; urinary tract MRI was performed only in selected cases. All patients underwent surgery under general anesthesia, with at least three robotic trocars (8 mm) and one conventional trocar for the assistant; 2 accessory trocars were necessary in some cases, mainly at the beginning of the series. Most procedures in our series were associated with a transobturator suburethral sling for the treatment of stress urinary incontinence or prevention of its appearance after prolapse repair. Our results are comparable to those reported in other larger series in terms of operative time, hospital stay and early or late complications. Pending an evaluation on the long term with larger series, we can include robot assisted colposacropexy among the therapeutic options for symptomatic pelvic floor prolapse repair.

[Nephron sparing surgery for the treatment of renal carcinoma in a functioning graft: case report]. / Cirugia conservadora de cancer renal en injerto funcionante: a proposito de un caso.

OBJECTIVE: We present nephron sparing renal surgery as a therapeutic option for the conservative treatment of renal cancer by reporting one case of de novo renal cell carcinoma (RCC) presenting in a functioning renal graft. METHODS/RESULTS: We describe one case of de novo RCC presenting in a functioning renal graft 51 months after transplantation. Tumorectomy was carried out with a margin of normal parenchyma and the base was free of tumor. Definitive pathologic study showed type I papillary renal cell carcinoma, Fuhrman grade 2, pathological stage I with free margins. There were not post operative complications and immunosuppression therapy was not modified. After almost three years of follow-up there is no evidence of tumor recurrence and an adequate renal function. CONCLUSIONS: Renal graft RCC is rare. Conservative surgery in selected patients may be a safe and effective technique when the tumor appears in a functioning graft, because it offers good oncological control and preserves renal function, avoiding transplant nephrectomy and the need of haemodialysis.

[En bloc transplantation of pediatric donor kidneys to adult receptors]. / Trasplante en bloque de riñones procedentes de donantes pediatricos en receptores adultos.

OBJECTIVES: Analysis of all pediatric donor en bloc transplants to adult receptors performed in our department. METHODS: Retrospective analysis of 73 en bloc kidney transplants and 497 adult transplants performed in our centre from 1990 to 2004. Mean follow-up was 50.23 months (10.18-89.05 months). All patients received the same immunosuppression, although it evolved with time. RESULTS: There were significant differences in terms of nonfunctioning kidneys and delayed graft function, more frequent in pediatric en bloc and adult transplants, respectively. Pediatric kidneys provided better renal function and less proteinuria. Patient and graft survivals were similar in both groups. One and five-year graft survivals were 83.56% and 8 1.47% for pediatric donor kidneys, and 91.50% and 86.99% for adult donor kidneys. Vascular complications were the most frequent cause of graft loss for the en bloc transplants. CONCLUSIONS: Pediatric donor en bloc transplants have an excellent survival and function in the middle and long-term. Vascular complications are the main cause of pediatric donor graft loss. The adoption of a pediatric donor en bloc transplant program increases the transplant activity.
