RESUMO
INTRODUCTION: Improved life expectancy and prenatal screening have changed the demographics of spina bifida (spinal dysraphism) which has presently become a disease of adulthood. Urinary disorders affect almost all patients with spinal dysraphism and are still the leading cause of mortality in these patients. The aim of this work was to establish recommendations for urological management that take into account the specificities of the spina bifida population. MATERIALS AND METHODS: National Diagnosis and Management Guidelines (PNDS) were drafted within the framework of the French Rare Diseases Plan at the initiative of the Centre de Référence Maladies Rares Spina Bifida - Dysraphismes of Rennes University Hospital. It is a collaborative work involving experts from different specialties, mainly urologists and rehabilitation physicians. We conducted a systematic search of the literature in French and English in the various fields covered by these recommendations in the MEDLINE database. In accordance with the methodology recommended by the authorities (Guide_methodologique_pnds.pdf, 2006), proposed recommendations were drafted on the basis of this literature review and then submitted to a review group until a consensus was reached. RESULTS: Bladder dysfunctions induced by spinal dysraphism are multiple and varied and evolve over time. Management must be individually adapted and take into account all the patient's problems, and is therefore necessarily multi-disciplinary. Self-catheterisation is the appropriate micturition method for more than half of the patients and must sometimes be combined with treatments aimed at suppressing any neurogenic detrusor overactivity (NDO) or compliance alteration (anticholinergics, intra-detrusor botulinum toxin). Resort to surgery is sometimes necessary either after failure of non-invasive treatments (e.g. bladder augmentation in case of NDO resistant to pharmacological treatment), or as a first line treatment in the absence of other non-invasive alternatives (e.g. aponeurotic suburethral tape or artificial urinary sphincter for sphincter insufficiency; urinary diversion by ileal conduit if self-catheterisation is impossible). CONCLUSION: Spinal dysraphism is a complex pathology with multiple neurological, orthopedic, gastrointestinal and urological involvement. The management of bladder and bowel dysfunctions must continue throughout the life of these patients and must be integrated into a multidisciplinary context.

PURPOSE: Very few studies have sought prognostic factors after adrenalectomy for metastasis. The aim of this study was to assess prognostic factors for oncological outcomes after adrenalectomy for adrenal metastasis. METHODS: All adrenalectomies for metastases performed in seven centers between 2006 and 2016 were included in a retrospective study. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Prognostic factors for CSS and RFS were sought by Cox regression analyses. RESULTS: 106 patients were included. The primary tumors were mostly renal (47.7%) and pulmonary (32.3%). RFS and CSS estimated rates at 5 years were 20.7% and 63.7%, respectively. In univariate analysis, tumor size (HR 3.83; p = 0.04) and the metastasis timing (synchronous vs. metachronous; HR 0.47; p = 0.02) were associated with RFS. In multivariate analysis, tumor size (HR 8.28; p = 0.01) and metastasis timing (HR 18.60; p = 0.002) were significant factors for RFS. In univariate analysis, the renal origin of the primary tumor (HR 0.1; p < 0.001) and the disease-free interval (DFI; HR 0.12; p = 0.02) were associated with better CSS, positive surgical margins with poorer CSS (HR 3.4; p = 0.01). In multivariate analysis, the renal origin of the primary tumor vs. pulmonary (HR 0.13; p = 0.03) and vs. other origins (HR 0.10; p = 00.4) and the DFI (HR 0.01; p = 0.009) were prognostic factors for CSS. CONCLUSION: In this study, tumor size and synchronous occurrence of the adrenal metastasis were associated with poorer RFS. Renal origin of the primary tumor and longer DFI were associated with better CSS. These prognostic factors might help for treatment decision in the management of adrenal metastasis.

OBJECTIVES: To report our experience of inflating or changing pressure balloon to treat recurrent urinary incontinence after AMS800® implantation instead of changing all the devices. PATIENTS AND METHODS: A retrospective study was conducted in a tertiary reference center between 2005 and 2015. All patients, treated by AMS800® implantation for post-prostatectomy urinary incontinence and whom balloon was subsequently changed or inflated, were included. Main clinical end point was the need for another surgery. Secondary end points were urethral erosion, infection, and efficacy on pad test and pad use. RESULTS: Thirty-one patients were included. All had had a 61-70cm H20 balloon implanted, with a single cuff (13 with transcorporeal placement). Twenty-one patients had their balloon changed for a 71-80cm H20 type, while 10 patients had their balloon refilled (median 3mL [range 2-7]). Median follow-up was 23 months (range 1-129). Overall rate of another subsequent surgery was 48.3% (n=15). Erosion and atrophy occurred more frequently after balloon repressurizing than after balloon replacement (80% vs 33%, P=0.024). At last follow-up, median pad use was higher in repressurizing group (2 vs 1, P=0.033). CONCLUSION: Balloon repressurizing is associated with a higher erosion and reoperation rate than changing pressure balloon. Continence results seem better when PRB is changed. It could be an alternative instead of changing all devices in patients with frail urethra. LEVEL OF EVIDENCE: 4.

OBJECTIVES: To report long-term outcomes after I-Stop TOMS™ implantation for PPI. PATIENTS AND METHODS: A retrospective evaluation was conducted in three tertiary reference centers. All consecutive patients implanted with an I-Stop TOMS™ sling between 2007 and 2012 for mild to moderate PPI (24-hour Pad test<400g) without history of pelvic radiation therapy were included. Evaluation had been conducted preoperatively, at one and six months postoperative and yearly thereafter. The main outcome criterion was the number of pads per day. Secondary criteria were International Consultation on Incontinence Questionnaire (ICIQ), SF-36 questionnaire, and complications. RESULTS: A hundred patients were evaluated with a median follow-up of 58months [19-78]. Pad use was significantly reduced and quality of life improved at last follow-up (P<0.0001). The percentage of patients dry and socially continent (0 or 1 pad) were 40% and 77% at 1 year, then dropped to 15% and 22%, respectively after 5years. Twelve patients were treated by artificial urinary sphincter implantation, five by ProACT™ balloons and one by a re-do I-Stop TOMS™. No severe complications were recorded at last follow-up. CONCLUSIONS: I-Stop TOMS™ implantation is a safe and effective option in the short-term for mild to moderate PPI management. However, a significant trend to recurrence of leakage has been established after long-term follow-up. If confirmed by further studies, these results may substantially impact patient information before male sling implantation. LEVEL OF EVIDENCE: 4.

OBJECTIVES: There is no strong evidence for second line therapy after male sling failure for post-prostatectomy urinary incontinence (PPUI). We report the outcomes after periurethral balloons implantation for persistence or recurrence of mild PPI symptoms after male sling implantation. METHODS: All patients implanted of a ProACT™ device (Uromedica, Inc., MN, USA) following I-STOP transobturator male sling (TOMS) failure, in a tertiary reference center between 2009 and 2016, were included. Patients were evaluated by 24-hour pad-test before and after implantation, and after each balloon repressurizing procedure. PGI-I and Likert scale patient satisfaction were estimated during a telephone interview conducted in 2016. Objective and subjective cure of urinary incontinence were defined by a 24-hour pad-test<8g and the use of zero or one pad per day, respectively. RESULTS: Fourteen patients were included. Median follow-up was 34months [4-89]. Objective and subjective cure were 29% (n=4) and 57% (n=8), respectively. Median pad-test decreased from 95g [IQR: 130] to 34g [IQR: 83] (P=0.022). ProACT™ significantly decreased median pad-test by a factor 2.73 [1.19-6.29]. Eighty-eight percent patients were feeling a little better, much better or very much better and 77% were satisfied or very satisfied at the end of follow-up. Reoperation rate was 28% (n=4): 3 balloons were changed for caudally migration (n=2) or deflation (n=1) and 1 had a urinary sphincter implanted for severe UI. CONCLUSIONS: ProACT™ is a safe and efficient treatment that can be used in second line therapy after TOMS failure for PPUI. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To develop a consensus of experts on the use of local estrogens in female urinary incontinence. MATERIAL AND METHOD: Following a formalized consensus method (DELPHI), a questionnaire was produced and sent to a first round and then to a second round of experts. The questionnaire consisted of proposals for recommendations for the use of local estrogens in the context of female urinary incontinence. The Survey Monkey® survey software allowed the questionnaire to be distributed and the answers obtained to be analyzed. RESULTS: Eight experts responded to the first round questionnaire. Seven formulations were deleted, 3 amended and 4 added to the first round questionnaire following expert advice. Twenty-six experts replied to the second round questionnaire, 24 of which were complete. Ten of the 21 proposals were approved at more than 80%, including five with strong agreement regarding the recognized benefit of local estrogens in urinary incontinence due to overactive bladder, the absence of data from the literature to demonstrate over-risk of hormone-dependent cancer under local estrogens and the need for follow-up of patients under this treatment. Six proposals were not the subject of a consensus and concerned the prescription modalities (maximum duration, effective minimum dose, prescription before surgery for incontinence). CONCLUSION: Although local estrogens did not have regulatory approval in urinary incontinence, more than 80% of these experts recognized their benefit in the management of urinary incontinence in women with vulvo-vaginal atrophy, particularly in the case of urinary urge incontinence.

OBJECTIVE: Study of the learning curve of robot-assisted radical prostatectomy, evaluating intraoperative difficulties and postoperative complications according to Clavien-Dindo classification. PATIENTS AND METHODS: Retrospective study of our first 157 consecutive patients treated with robot-assisted prostatectomy for localized prostate cancer between September 2011 and December 2014. Comparison of learning for each group of 50 procedures and then comparison between patients operated on by a pair of two seniors specially trained for robotic surgery and patients operated on by one mixed pair including a surgeon junior coached by one senior of the first group. RESULTS: Only postoperative complications decreased significantly from the 51st patient (P=0.04). The curves showing the evolution of the operative time decreased with a parallel trend between the two pairs, but with more variability in the mixed pair. There was no significant difference in terms of intraoperative difficulties (P=0.59), nor postoperative complications (P=0.56) mainly of grade 2. The blood loss, transfusion rate, duration of hospitalization and readmission rates did not differ. Lymph node dissection did not affect outcomes. For oncological results, the overall rate of positive surgical margins (R+) was 30.6 % in the initial pair against 24.2 % in the mixed group with no significant difference. Nevertheless, the subpopulation study objectified a R+ rate of 12.86 % for pT2 against 42.85 % for pT3. CONCLUSION: The early involvement of a junior surgeon who did not receive specific training, but benefiting from the guidance of a senior surgeon, did not compromise the results while allowing a faster learning curve with a rate of operative complications close to the one observed by the senior pair.

AIM: Holmium laser enucleation of prostate (HoLEP) is renowned for the difficulty of its learning curve. Our aim was to evaluate the interest of a three-step tutorial in the HoLEP learning curve, in a university center. METHODS: It is a retrospective, monocentric study of the 82 first procedures done consecutively by the same operator with a proctoring in early experience and after 40 procedures. For all patients were noted: enucleation efficiency (g/min), morcellation efficiency (g/min), percentage of enucleated tissue (enucleated tissue/adenome weigth evaluated by ultrasonography. g/g), perioperative morbidity (Clavien), length of hospital stay, length of urinary drainage, functional outcomes at short and middle term (Qmax, post-void residual volume [PVR], QOL scores and IPSS at 3 and 6months). RESULTS: Enucleation and morcellation efficiency were significantly higher after the second proctoring (0.87 vs 0.44g/min; P<0.0001 and 4.2 vs 3.37g/min, P=0.038, respectively) so as the prostatic volume (43.5 vs 68.1mL, P=0.0001). Percentage of enucleated tissue was higher in the second group, however, the difference was not significant (69.5% vs 80.4%, P=0.03). Per- and postoperative complications, hospital length of stay, urinary drainage length and functional results at 3 and 6months were not significantly different. CONCLUSION: The learning curve did not interfere with functional results. The second proctoring was essential to us in order to grasp the technique. These data underlined the necessity of a pedagogic reflexion in order to built a standardized formation technique to the HoLEP. LEVEL OF EVIDENCE: 4.

BACKGROUND: Sacral nerve stimulation (SNS) is an alternative surgical treatment of refractory urge incontinence and/or fecal incontinence. Despite its clinical efficacy, the mechanisms of action of SNS remain poorly understood. The aim of this experimental study was to evaluate the effect of SNS on visceral mechanosensitivity in rats. METHODS: Anesthetized Sprague-Dawley rats were treated with SNS or sham stimulation. SNS was performed by implanting an electrode close to the sacral nerve root S1. Rats were administered either a non-selective opioid receptor antagonist (naloxone) or a nitric oxide synthase inhibitor (L-NAME). Colonic mechanosensitivity was evaluated using the variation of arterial blood pressure as a spino-bulbar reflex in response to graded isobaric colorectal distension (CRD). C-fos immunoreactive neurons were quantified in spinal and supraspinal sites. µ-opioid receptor (MOR) internalization was counted in the sacral spinal cord with sham or effective SNS in response to CRD. KEY RESULTS: SNS reduced visceral mechanosensitivity in response to CRD. This effect was reversed by intrathecal and intraveinous naloxone administration. In both models, CRD induced increased c-fos immunoreactivity in the dorsal horn neurons of the sacral spinal cord and supraspinal areas. This increase was prevented by SNS. MOR internalization was significantly higher in stimulated group. CONCLUSIONS & INFERENCES: SNS impacts on visceral mechanosensitivity by decreasing the spino-bulbar reflex in response to CRD. Spinal opioid receptors are likely involved in this effect.

Objective The aim of our study was to assess short and mid-term clinical efficacy of external beam radiation therapy to achieve hemostasis in patients with bladder-cancer related gross hematuria who were unfit for surgery. We also assessed hypofractionation as a possible alternative option for more severe patients. Patients and Methods Thirty-two patients were included for hemostatic radiation therapy, with two schedules based on Eastern Cooperative Oncology Group performance status. The standard treatment was 30 Gy in 10 fractions over 2 weeks. More severe patients underwent a hypofractionated regimen, with 20 Gy in 5 fractions over a one week period. Clinical evaluation was performed at 2 weeks and 6 months. Results At 2 weeks, 69% of patients were hematuria-free. Subgroup analysis showed that 79% of patients undergoing hypofractionated regimen were hematuria-free. A total of 54% were hematuria-free with the standard regimen. Based on tumor stage, hematuria was controlled at 2 weeks for 57% of non-muscle invasive tumors and 72% of muscle-invasive tumors. After 6 months, 69% of patients had relapsed, regardless of tumor stage or therapy schedules. Conclusions Hemostatic radiotherapy is an effective option for palliative-care hematuria related to bladder cancer in patients unfit for surgery. Although it appears to be rapidly effective, its effect is of limited duration. Hypofractionation also seems to be an effective option; however larger cohorts and prospective trials are needed to evaluate its efficacy compared to standard schedules. .

PURPOSE: The aim of this study was to present the results of the 2 year outcome of I-Stop TOMS™ transobturator sling for post-prostatectomy (UIPP) minor to moderate male urinary incontinence treatment. MATERIALS AND METHODS: A prospective, single center study, including 26 patients with minor to moderate IUPP and operated on using a suburethral sling (MS) TOMS™ (four arms) was performed. UIPP assessment was made preoperatively and 1 year postoperatively, using validated questionnaires (SF36 and ICIQ), number of pads daily, and the 24 hours Pad-test (LPT). Telephone follow-up evaluation was performed in 21 patients over a 2 years period following surgery. RESULTS: Radical prostatectomy was performed 48.4 months earlier and average patient age was 67.3 years. Preoperatively, the mean number of pads used daily was 2.3 with an average weight loss of 207.1grams at LPT. At 1 year, ICIQ and SF36 scores significantly improved. Weight loss in the LPT as well as the number of pads significantly decreased (P<0.05). At 1 year, 13 patients were cured, 12 were improved, one reached improvement criteria, and 96.2% using a pad daily maximum. With more than a 2 year follow-up, 10/21 patients were dry, nine improved and two failed, and 90.5% using 0 to 1 pad per day. CONCLUSIONS: The transobturator TOMS™ male sling is a simple and well-tolerated procedure permitting a significant improvement of UIPP, with 50% of patients achieving complete continence at 1 year postoperatively, these good results continued beyond 2 years. LEVEL OF EVIDENCE: 4.

The incidence of post-traumatic syringomyelia (PTS) is estimated according to recent studies at 25 to 30% of patients with traumatic spinal cord injuries in magnetic resonance imaging (MRI), which remains the gold standard exam for syringomyelia diagnosis and monitoring. Syringomyelia is translated by an increased cord signal (similar to CSF) with low-density T1-weighted image and high-density T2-weighted image, which extends beyond site of initial lesion at least to two vertebral segments. Two conditions are required for development of PTS: traumatic spinal cord injury and blocked the flow of CSF epidural. The mean interval from spinal cord injury to diagnosis SPT was 2.8years (range, 3months to 34years). The commonest symptoms are pain and sensory loss. PTS should be suspected if the patient has new neurological symptoms above level of injury, such as dissociated sensory injuries, reflexes abolition, and motor deficit, after the neural function becomes stable for certain time. In urologic practice, new neurological symptoms could be bladder and/or erectile dysfunction. The medical management based on prevention efforts with closed-glottis pushing, which could aggravate the syrinx cavity. In urology, extracorporeal shockwave lithotripsy, and laparoscopic or robotic surgery could extend the syrinx cavity for the same reason (increase abdominal pressure). The indications for surgical intervention and optimal surgical treatment technique for patients with PTS are not consensual. The literature demonstrated that surgery PTS is effective at arresting or improving motor deterioration, but not sensory dysfunction or pain syndromes.

AIMS: To evaluate the feasibility, the efficiency, the results of continent cystostomy in adult population. MATERIAL AND METHODS: Retrospective study of patients who underwent a continent cystostomy between 1987 and 2011. RESULTS: Forty-three patients underwent a continent cystostomy (13 men and 30 women). The mean age at surgery was 53.4±14.6years. The mean BMI was 25kg/m(2). No death in relation with the cystostomy was reported. Thirty-two patients had a neurological pathology (74.4%), 11 a pathology other than neurological (25.6%). A retention bladder was reported for 12 patients (27.9%), 17 (39.5%) were incontinent, and 14 (32.6%) had a mixed symptomatology. All patients had urodynamics and an evaluation of the urinary tract. Nineteen appendicovesicostomy were made, 15 double Monti-procedure, six simple Monti-procedure, three channels were made of an association of ileon and appendix. Seventeen patients underwent an augmentation cystoplasty in combination with the continent catheterizable conduit. The mean follow-up was 47.6±29months. Continence was achieved in 37 patients (86%), two patients underwent a Bricker. Stomal stenosis occurred in eight patients (18.6%), with a median time of 16.1±20.4 months. Leakage occurred after bladder neck closure for two patients (4.6%). Clean intermittent catheterization were performed by 30 patients, catheterization by a care giver for four patients, seven did not use their stomy because of the evolution of their causal pathology, or because of an intercurrent pathology. No difference between the channels (Mitrofanoff versus Monti) was reported. CONCLUSION: Continent catherizable cystostomy were a feasible method of continent urinary diversion in an adult population. This study demonstrated their feasibility in an adult population and their long-term efficiency with a mean follow-up of 47.6months and 127months for one of them. With a rate of continence upper than 80%, it was an effective technique of urinary diversion associated with intermittent catheterization.

Leiomyoma is a frequently uterine tumour. Its location on the urinary tract is rare, making its iconographic diagnosis difficult. The ablation is often realized, allowing the histological confirmation. Renal leiomyoma have good prognosis. In our patient, the CT scan discovered a spontaneously hyperattenuating renal mass, raising after injection of contrast, at a 48-year-old patient. MRI revealed in particular a hyposignal T2. Because of its capsular location, the possibility of a renal leiomyoma had been envisaged without being able to eliminate a malignant lesion. The histological exam confirms this benign hypothesis. So leiomyoma is a rarely renal tumour, of excellent prognosis. The progress of the imaging allows the characterization of these hurts today and could, can be, in a near future, be an alternative at surgery.

PURPOSE: Clinical study among men suffering from postprostatectomy urinary incontinence comparing the short term Pad-Test to urinary symptom questionnaires. PATIENTS AND METHODS: From June 2006 to November 2008, 16 patients presenting a urinary incontinence after prostatectomy have been operated by I-Stop® TOMS male sling. The incontinence has been evaluated by analyzing data from the short Pad-Test, ICIQ and SF36 questionnaires. This evaluation has been done before surgery (Day 0) and 90 days after (Day 90). The short term Pad-Test was recommended by the International Continence Society. The analysis between the values has been appreciated by Kendall ratio with a significant value, for the independence test, if smaller than 0.05. RESULT: We can't demonstrate any significant evolutive correlation of the short term Pad-Test and ICIQ or SF36 questionnaires results between Day 0 and Day 90. At Day 0, there is no significant link between short-term Pad-Test and ICIQ or SF36 questionnaires results. CONCLUSION: The absence of correlation between the two evaluations before surgery confirms the interest of a double evaluation, objective and subjective. The short-term Pad-Test is easy to perform but presents a limited variability of the measure and a lack of precision in leakage detection. Nevertheless, there is a bias of selection in the recruited population who suffered from a minor or moderated urinary incontinence after prostatectomy, according to Stamey standards. The authors propose to prefer 24 hours Pad-Test which evaluate the leakage on a larger period of time.

PURPOSE: We evaluate the efficacy of hyaluronate acid instillation for treatment of interstitial cystitis (IC). PATIENTS AND METHODS: From March 2008 to May 2009, a prospective study included 31 patients. We used the new definition of IC established by the ICS in 2002. Patients have a urinalysis, a cystoscopy, a hydrodistension test and bladder biopsies. The urodynamic evaluation was not systematic. Patients received weekly six instillations of 40mg (50ml) intravesical hyaluronate acid. We evaluated the efficacy and safety of treatment with two specific questionnaires of interstitial cystitis filled before and after 6 weeks of treatment: the O'Leary-Sant and Pelvic pain and Urgency/Frequency (PUF). RESULTS: Four groups were defined: good response, partial response, poor response and no response. They were composed by 14 patients (45%), two (7%), seven (22%) and eight patients (26%). We obtained 52% positive response (good response and partial response) after 6 weeks of treatment. Patients with cystoscopy and histology abnormal had a response rate of 60%. No serious side effects were observed. CONCLUSIONS: Hyaluronate acid has a place in the treatment of interstitial cystitis with an efficiency comparable to other treatments and good tolerance. The response rate to treatment can be improved by better selection of patients, particularly those having a cystoscopy and histology abnormal.

The incidence of vesicoureteral reflux (VUR) varies between 10% and 80% of transplanted kidneys. In cases of failure of endoscopic treatment or recurrent urinary tract infections, surgical correction is proposed by ureteral reimplantation or pyeloureteral anastomosis using the native ureter. The aim of this study was to assess the results of a technique that increases the submucosal length of the ureter without a ureterovesical reimplantation. We treated 12 patients with VUR in the transplanted kidney by open surgery. Retrograde cystography showed resolution of reflux in all the patients. Our technique has the advantage of avoiding ureteral dissection thereby avoiding its devascularization and no invasion of the bladder mucosa.

CONTEXT: In aging males, there is an increased prevalence of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) whose affect significantly their quality of life. LUTS would represent for ED an independent risk factor. Some treatment of LUTS have undesirable effects on the erectile function. The phosphodiesterase type 5 inhibitors (IPDE 5) revolutionized the treatment of ED. Several recent clinical studies evaluated the effect daily treatment by IPDE 5 on the LUTS secondary to BPH among patients with or without ED. MATERIALS AND METHODS: we searched Medline for the peer-reviewed articles in English published, pertaining to findings of potential interest supporting a role of IPDE5 in LUTS due to BHP. The keywords used were: benign prostatic hyperplasia; cyclic nucleotide phosphodiesterase type 5; lower urinary tract symptoms; erectile dysfunction. RESULTS: Generally, daily treatment with IPDE 5 improves the LUTS secondary to BPH as well as in both the storage and voiding domains of the international prostate symptom score (IPPS) and in quality of life questionnaire. It was not observed adverse events. CONCLUSION: The first results of the use of IPDE 5 in the LUTS treatment secondary to the HBP seem promising. However, a direct comparison of efficacy of IPDE 5 and alpha-blockers or 5-alpha-reductase inhibitors is not yet available. The mechanism(s) of action(s) of these compounds in this indication remain difficult to affirm even if new hypotheses can be formulated.

INTRODUCTION: The aim of this study was to evaluate frequency and management of vascular complications in renal allograft. PATIENTS AND METHODS: We performed retrospective analysis of patients who underwent renal allograft from 2001 to 2006 at our university hospital center. In order to access peri- and postoperative vascular complications, data were also obtained from donors and receivers, as well as organ procurement and renal transplant procedure. RESULTS: One hundred and seventy-nine files were analyzed with a median follow-up of 40 months, mean age of donors was 40.4+/-11.2 years and 46.01+/-10.6 years for receivers. Seventy-two allograft patients had at least one vascular complication, with 32 cases of renal arterial stenosis, 28 cases of hematoma with surgical exploration required in seven cases, four cases of arterial thrombosis, two cases of venous thrombosis and one arterial dissection. Our series underlines that tobacco abuse in donors is a risk factor for vascular complication (p=0.043), as well as glomerular nephropathy (p=0.0185), coagulopathy (p=0.0165) and hemodialysis (p=0.02) are risk factors for receivers. Multiple arteries in renal allograft (p=0.03) and calcification on aortic patch (p=0.0274) would present a greater risk of postoperative complications. Our results demonstrate that the following parameters i.e., postoperative transfusion (p=0.011), heparin therapy (p=0.0085), immunosuppression (p=0.0478), and peri-operative aminovasopressive drugs (p=0.086) could also be implicated in vascular complication occurrence. CONCLUSION: A careful selection of donors remains a major factor for renal allograft quality, however arterial evaluation and coagulopathy detection in receivers must also be performed prior to transplantation procedure. A multidisciplinary approach (nephrologist, urologist, anesthesist) will optimize vascular ischemia delay and also reduce early and late vascular complications, which could have possible consequences on renal allograft and patient survival.
