[Factors predicting of failure after conservative treatment in III-V grade renal trauma]. / Facteurs prédictifs d'échec du traitement conservateur du traumatisme rénal grade III­V.

INTRODUCTION AND OBJECTIVES: Surgical exploration of renal injury secondary to major trauma often leads to nephrectomy. The aim of this work was to identify the factors associated with the need for surgery in patients with III-V grade renal trauma who were initially managed conservatively. MATERIALS AND METHODS: We retrospectively reviewed data from patients with Grade III-V kidney injury between June 2005 and June 2015. Demographic, clinical and bio-radiological characteristics at admission and follow-up, as well as management and complications, were recorded. Patient data, including conservative treatment, was a success without recourse to nephrectomy, and those patients who needed surgery were analyzed. RESULTS: Seventy three patients were included in this study. Grade III accounted for 45%, Grade IV: 49% and Grade V: 5%. The success rate for conservative treatment was 79%: 31 patients grade III (94%), 26 grade IV (72%) and no grade V patients. hypotension at admission (P=0.04), hematoma size greater than 3.5 centimeters (P=0.002), grade V (P=0.003), anemia (P=0.04), blood transfusion (P=0.01) and worsening of lesions of the control CT lesions (P=0.001), are the factors considered as predictive of failure of conservative treatment. CONCLUSION: Conservative management is the treatment of choice in III-V grade renal trauma, and the prognostic factors found in this study make it possible to better select patients.

[Evaluation of the learning curve of laparoscopic radical cystectomy for cancer: Morbidity and oncological results]. / Évaluation de la courbe d'apprentissage de la cystectomie radicale laparoscopique pour cancer : morbidité et résultats oncologiques.

INTRODUCTION: The objective of this work was to evaluate the impact of the laparoscopic radical cystectomy learning curve on perioperative and oncological outcomes. PATIENT AND METHODS: This is a retrospective and single-center study of all patients who underwent laparoscopic radical cystectomy for bladder cancer from February 2007 to March 2016, (93 patients) Perioperative and oncological data were collected. We used mixed statistical models to predict the number of patients needed in the learning phase. We compared the perioperative parameters of the patients in the learning phase with those of the rest of the patients. Overall survival was estimated using the Kaplan-Meier method. RESULTS: Thirty-six patients are required for the learning phase (P1). The expertise phase begins after the 36th LRC (P2). In both phases, there was no significant difference in age, ASA score, and tumor stage (P=0.237, P=0.577, P=0.998). Mean operative time was 328.3min and 262.4min in P1 and P2 (P=0.0001), mean blood loss was 333.7mL and 194.3mL in P1 and P2 respectively (P=0.0003). The rate of major complications was high in the learning phase (P=0.042). There was no significant difference in lymph node yield, positive surgical margins and overall survival (P=0.068, P=0.194, P=0.703). CONCLUSION: This learning experience was evaluated without compromising oncological results, but with a significantly higher rate of major complications. LEVEL OF EVIDENCE: 3.

[Oncological results of a series of 93 laparoscopic radical cystectomies: 5 years of follow-up]. / Résultats oncologiques d'une série de 93 cystectomies totales laparoscopiques : 5 ans de suivi.

OBJECTIVE: To report oncological results at 5 years after laparoscopic radical cystectomy (LRC) with lymph node dissection for bladder cancer (BC). PATIENTS AND METHODS: This is a retrospective single-center study of all patients who underwent LRC for BC by the same surgeon from February 2007 to March 2016. Demographic, perioperative and oncologic data were collected. We reported overall survival rate (OS), cancer specific (CSS) and recurrence-free survival (SSR), as primary indicators of oncologycal outcomes. These survival rates were estimated according to the Kaplan-Meier method. Log-rank tests were used to explore overall survival according tumor stage, lymph node involvement and surgical margins status. RESULTS: In all, 93 patients (82 men and 11 women) underwent LRC. Mean age was 59 years. Minor complications (Clavien I-II) occurred in 24.7%. Major complications (Clavien IIIa-V) were observed in 8.6%. No patients received neoadjuvant chemotherapy. Median lymph node (LN) yield was 15 and 26.5% patients had positive LN. The positive surgical margins (SMs) rate was 5.3%. Median follow-up for the entire patients was 50 months (19-84 months). Forty-three patients (46.2%) were followed for at least 71 months. Five year RFS, CSS and OS were 67%, 85% and 79%, respectively. Non organ confined desease, positive LN and positive SMs were associated with poorer OS (P<0.039, P<0.016 and P<0.001). CONCLUSION: LRC was associated with acceptable long-term oncologic outcomes, similar to those currently reported after open cystectomy for BC. LEVEL OF EVIDENCE: 3.

[The local anesthesia for the prostatic biopsies echo-guided: forward-looking randomized study comparing two methods]. / L'anesthésie locale pour les biopsies prostatiques écho-guidées: étude prospective randomisée comparant deux méthodes.

INTRODUCTION: The realization of the prostatic biopsies is a painful act. The objective of our work was to compare the analgesic efficiency of the injection of the lidocaine at the level of periprostatics laterals and apical areas compared with the use of gel of lidocaine intrarectal associated with the taking of oral tramadol. PATIENTS AND METHODS: Between November 2007 and December 2009, 60 patients admitted in the service of urology of the university hospital Mohammed VI of Marrakesh for prostatic biopsies were randomized in two groups. The group 1 (30 patients) received two tablets from tramadol 50mg with 10 mL of gel of lidocaine 2% intrarectal while 30 patients of the group 2 received 10 mL from lidocaine 2% injected at the level of periprostatics laterals and apicales. The pain was estimated by a visual analog scale (AVS) at the introduction of the probe of echography (AVS 1), at the time of the biopsy (AVS 2) and 20 minutes later (AVS 3). RESULTS: There was no significant difference between both groups concerning AVS 1 means. The average score of the pain was significantly lower in the group 2 for the AVS 2 and AVS 3. CONCLUSION: The periprostatics anesthesia assured a better control of the pain at the time of the prostatic biopsy and 20 minutes later, without increase of the complications. We recommend it to decrease the pain and the discomfort related to this technique.

[Perineal-scrotal gangrene: epidemiological and therapeutic aspects. About 45 cases]. / La gangrène périnéoscrotale: profil épidémiologique et aspects thérapeutiques. À propos de 45 cas.

Perineoscrotal gangrene is an acute disease, a rare and severe affection of the perineum, whose evolution is unpredictable and rapidly extensive. The diagnosis is clinical. The paraclinical examinations allow early diagnosis and assessment of anatomical and biological repercussions. We conducted a retrospective study of 45 patients spread over six years, involving a multidisciplinary team consisting of three specialists (urologists, visceral, plastic surgeons). The average age was 52 years. The largely male dominated our series. Fournier gangrene was the most common etiology. We noted five cases of death (11%) in the acute phase, secondary to septic shock (four patients) or multiple organ failure (one patient). The evolution was favorable in 40 other patients in the series, requiring an initial management in intensive care unit, and surgical treatment. The average hospital stay was 17 days. After the acute phase, all patients underwent a surgery for skin coverage, ranging from guided healing (two patients) to musculocutaneous flap of the gracilis (six patients) via the secondary suture (four patients), the burying the testes (18 patients) and half thick skin graft, with a functional and aesthetic result was acceptable, and minimal sequelae. In our series, the most predictive prognostic factors would be the delay of care, sepsis on admission and associated diseases.

Malignant epithelioid renal angiomyolipoma involving the inferior vena cava in a patient with tuberous sclerosis.

Renal angiomyolipomas (AMLs) are mesenchymal tumors that occur either sporadically or are associated with tuberous sclerosis, and are generally considered to be benign. Malignant AML is extremely rare, and most are found to be epithelioid histopathologically. The authors report the case of a patient followed for renal AML. On CT surveillance, this lesion developed features of a malignant tumor involving the renal vein and inferior vena cava. The patient was treated by nephrectomy and tumor thrombectomy with retroperitoneal lymph node dissection. Histological examination demonstrated renal AML with a malignant epithelioid contingent. The various aspects of this histological and radiological variant are discussed.

Lymphoproliferative disorder presenting as a tumor of the renal allograft.

Post-transplant lymphoproliferative diseases (PTLDs) constitute a group of potentially life-threatening complications in solid organ transplantation, occurring in 1-2% of kidney transplant recipients. The absolute number of cases occurring at each transplant center remains small, making it difficult to assess incidence, prognosis, and treatment. We report a case of post-transplant lymphoproliferative disorder that developed in the allograft renal parenchyma 2 years after renal transplantation. This case implies that partial nephrectomy may be a safe and effective treatment protocol for renal lymphoma in allograft kidneys.

Factors influencing adrenal metastasis in renal cell carcinoma.

OBJECTIVES: We determine the incidence and characteristics of adrenal involvement in localized and advanced renal cell carcinoma, and evaluate the role of adrenalectomy as part of radical nephrectomy. MATERIAL AND METHODS: From 1993 to 1999, 210 patients with renal cell carcinoma (RCC), (139 men and 71 women, mean age 60.8 years, range 12-96) underwent radical nephrectomy with associated adrenalectomy. Patients were divided into two subgroups of 106 with localized (stage T1-2 tumor, groupl) and 104 with advanced (stage T3-4N01M01, group2) renal cell carcinoma. A retrospective review of preoperative computerized tomography (CT) of the abdomen was performed. Radiographic findings were subsequently compared to postoperative histopathological results to assess the predictive value of tumor characteristics and imaging in determining adrenal metastasis. RESULTS: Of the 210 patients, 15 (7.1%) had adrenal involvement. Tumor stage correlated with probability of adrenal spread, with T3-4 and T1-2 accounting for 13.4% and 0.9% of cases, respectively (p < 0.001). Upper pole intrarenal RCC most likely to spread was local extension to the adrenal gland, representing 53.3% of adrenal involvement. In contrast, multifocal, lower pole and mid region RCC tumors metastasized hematogenously, representing 21.4%, 7%, and 14% of adrenal metastasis, respectively. The relationship between intrarenal tumor size (mean 7.8 cm, range 4 to 21) and adrenal involvement was not statistically significant. Preoperative CT demonstrated 97.7% specificity, 98.4% negative predictive value, 87% sensitivity and 80% positive value for adrenal involvement by RCC. CONCLUSIONS: Ipsilateral adrenalectomy should only be performed if a lesion is seen preoperatively on CT scan or if gross disease is seen at the time of nephrectomy. The prognosis is poor for RCC with ipsilateral involvement even with complete removal. Because of this poor prognosis we believe that adrenal involvement should constitute a separate stage category.

[Spontaneous subcapsular renal hematoma: diagnosis and treatment. Two case reports]. / Hématomes spontanés de la loge rénale: diagnostic et traitement. A propos de deux cas.

Spontaneous perirenal haematomas essentially raise the problem of the aetiological diagnosis, but can sometimes be inadequate. Arteriography is useful when CT scan is negative or in the case of vascular disease. The therapeutic attitude, nephrectomy or conservative treatment remains controversial, but in view of the frequency of renal neoplastic lesions, the authors recommend nephrectomy at the slightest doubt concerning renal integrity. When no case be found, the assessment must be completed postoperatively with long-term, close surveillance, due to the risk of an undiagnosed neoplastic lesion. The authors report two recent cases and try to propose a diagnostic and therapeutic strategy based on the aetiology.

Follicular carcinoma of the thyroid metastasis to the kidney nine years after resection of the primary tumor.

The authors report a case of renal metastasis from a follicular carcinoma of the thyroid in 62 years-old man, occurring nine years after isthmolobectomy for thyroid carcinoma. Clinical symptoms radiographic results and treatment are discuss after reviewing literature.

[Treatment of inflammatory urethral stenosis with endoscopic urethrotomy]. / Traitement des sténoses inflammatoires de l'urètre par urétrotomie endoscopique.

Urethral stricture, mainly consisting of cases of inflammatory stricture, is a frequent occurrence in Morocco. Numerous techniques have been proposed to treat these disorders, including internal endoscopic urethrotomy (IEU). Initially described by Otis and Maisonneuve using a blind approach, IEU was then further developed by Saches who carried out direct vision urethrotomy. It rapidly became established as the method of choice for primary treatment of urethral stricture, and classical surgery was limited to those cases in which this method had failed. However, although this technique is relatively simple and appears to be efficient, there is in fact a high relapse rate, necessitating repeated IEU; therefore at present there is a tendency to return to the classical methods of anastomotic resection and urethroplasty after the second or third IEU. Although the relapse rate is low for short, single or bulbar strictures, it is high for penile strictures and for those with accompanying severe periurethral fibrosis. In this study, we have reported the results of a homogeneous series of 149 cases of urethral stricture treated by internal urethrotomy. The aim of this retrospective study was to better define the indications for adopting this technique, and also to determine the reasons for failure. The various alternatives to IEU (resection, plasty) have been examined, as has their respective failure rate.

[Carcinomatous degeneration on augmentation ileocystoplasty for tuberculous bladder]. / Dégénérescence carcinomateuse sur iléocystoplastie d'agrandissement pour vessie tuberculeuse.

The development of cancer on the ileal graft after augmentation ileocystoplasty for benign bladder disease is a little known complication. The authors report a case of squamous cell carcinoma in the ileal bladder occurring 37 years after augmentation ileocystoplasty for tuberculous bladder, in a 68-year old patient. Carcinomatous degeneration is usually occurs more than ten years after cystoplasty. Patients treated by this operation must be submitted to annual cystoscopy combined with guided biopsies at the slightest doubt. This surveillance should be started between the 5th and the 10th postoperative year.

Leiomyosarcoma of the prostate: a study of two cases.

Leiomyosarcoma of the prostate is rare neoplasm that accounts for less than 0.1% of prostate malignancies. A number of treatment approaches have been adopted including radical surgery, radiotherapy and chemotherapy, but in no instance has a successful outcome been obtained. Prostate leiomyosarcoma has a poor prognosis, although survival time can vary. For these reasons, it is important to correctly identify this disease and report its occurrence, type of treatment, and the response to therapy of each patient diagnosed as having leiomyosarcoma of the prostate in an attempt to improve our understanding of the natural history of these lesions.

[Martius' technique in the treatment of complex vesicovaginal fistula]. / Technique de martius dans le traitement des fistules vésiculovaginales complexes.

Sixteen cases of vesicovaginal fistulae (including 14 urethrovaginal fistulae), were treated vaginally using Martius' procedure. The authors describe the technique for the interposition of a labial fat pad, between the bladder and the vagina. The results are good. Thirteen patients have been cured. In one case a second was necessary using Guittes technique. There was two failures.

[Percutaneous nephrostomy: indications, techniques and results. Retrospective study of 81 cases]. / La néphrostomie percutanée de drainage: indications, technique et résultats. A propos d'une série rétrospective de 81 cas.

A retrospective study has been made of 81 cases of percutaneous nephrostomy (PCN) which were treated during the period 1989-1998. The mean patient age was 41 years (age range: 21-66 years). The reasons for the diversion via nephrostomy catheter were oligoanuria (43 cases), pyonephrosis (34 cases), and evaluation of renal function (four cases). The initial disease was found to be malignant in 23.25% of cases of oligoanuria, with six cancers of the cervix, three bladder cancers and one prostate cancer. Lithiasis was the main etiology in subjects with benign disease, and was the causative factor of oligoanuria in 55.8% and pyonephrosis in 67.6% of cases, i.e., a total of 47 cases (58%). PCN catheter placement was successfully carried out in 100% of cases, and resulted in improved renal function, and/or in the treatment of the initial infectious syndrome in the majority of cases. PCN is an excellent technique for upper urinary tract drainage due to its simplicity, efficacy, ease of insertion, low cost and satisfactory results. It is a minimally invasive technique, which necessitates only the use of a local anesthetic, a sound knowledge of the human anatomy involved, a trained operator and a minimum of material.

[Secondary sclerosis of the prostatic compartment after surgical treatment of benign prostatic hypertrophy]. / Sclérose secondaire de la loge prostatique après traitement chirurgical de l'hypertrophie bénigne de la prostate.

In an 8-year period, 10 patients/1,280 developed bladder neck sclerosis following prostatectomy--an incidence of 0.78%. The mean age is 66 years (range 45-88).clinical signs of the disease are characteristic of infravesical obstruction confirmed by uroflow and X-ray examination. The best results for the treatment of the contracture were obtained after bladder neck incision and transuretral resection of the bladder neck contracture which gave--with mean follow-up of 12 months (range 7-24 months)--0% incidence of recurrence but after bladder neck dilatation it rose 100%.

[Renal cancer in adults. Review of 68 cases]. / Cancer du rein de l'adulte. A propos de 68 cas.

The authors report a series of 68 cases of renal cancer observed over a 9-year period. Patients consisted of 33 women (49%) and 35 men (51%), with a mean age of 53 years (range: 23-85 years). The clinical features were polymorphic, dominated by loin pain (44%), haematuria (37%), a lumbar mass (19%), alteration of the general state (7%). The diagnosis was established by ultrasonography in 59 patients and CT-scan in 63 patients. The mean tumour diameter was 11 cm (4-22 cm) and two cases presented bilateral tumours. The time to diagnosis ranged from 1 month to 7 years. Staging reflected the advanced stage of the cancer. Treatment was surgical for 58 patients (58%). A lumbar incision was performed, in 40% of cases. Radical nephrectomy was performed in 82%, and partial nephrectomy was performed in 3% of patients. Histological examination of the specimen showed renal cell carcinoma in 75% of cases. The lymph nodes removed were invaded in 20% of cases. The mean follow-up was 29 months (6 to 84 months), normal at one year for 44 patients (86%) and at 5 years for 16 patients (31%). Tumour recurrence in the renal compartment was observed in 2 patients (4%). Asynchronous metastases occurred in 11 patients (21.5%) after 21 months. (range: 12-48 months). The overall 5-year survival was 100% T1, 69% T2 and 50% T3.

[Desmoid tumor of the mesentery secondary to colectomy. An exceptional cause of ureteric obstruction]. / Tumeur desmoïde du mésentère secondaire à une colectomie. Une cause exceptionnelle d'obstruction urétérale.

Desmoid tumours are rare lesions with a local invasive potential and a risk of recurrence, considered to be benign due to the absence of metastases. They are classified as fibromatoses and may be associated with Gardner's syndrome. The authors report an unusual case, in a 33-year-old woman, of a desmoid tumour invading the right ureter with upper tract dilatation. Etiologic factors (traumatic, hormonal, auto-immune...) are discussed, together with the treatment of choice to lower the risk of recurrence.

[Arterial embolization in hemorrhagic renal angiomyolipoma]. / L'embolisation artérielle dans les angiomyolipomes rénaux hémorragiques.

OBJECTIVE: Renal angiomyolipoma (AML) is a rare benign tumour (2-3%) comprising variable proportions of an adipose component, which is often the most abundant, a smooth muscle contingent and a vascular contingent. The objective of this study is to demonstrate the value of embolization of bleeding angiomyolipomas. MATERIAL AND METHODS: 2 patient, aged 22 and 62 years, presented with perirenal haematoma secondary to bleeding angiomyolipoma and were treated by selective arterial embolization. RESULTS: In one case, partial nephrectomy was subsequently performed because of the size of the angiomyolipoma (10 cm). In the other case, attempted partial nephrectomy at 3 months failed due to the proximity of the renal hilum and nephrectomy was performed. CONCLUSION: Beyond a diameter of 4 cm, the risk of perirenal haemorrhage is proportional to the size of the tumour. When surgery is required, selective arterial embolization is the first stage of treatment allowing partial nephrectomy in the majority of cases.

Leiomyosarcoma of the renal pelvis.

We report a case of renal leiomyosarcoma arising from the renal pelvis with immunohistochemical confirmation of the diagnosis. In this instance clinical presentation and imaging finding are not helpful in accurately establishing the diagnosis preoperatively. Wide surgical excision would appear to be the treatment of choice.
