[Perineo-transpubic approach to the management of posterior urethral post-traumatic rupture]. / La voie périnéo-trans-symphysaire dans le traitement des ruptures traumatiques de l'urètre postérieur.

OBJECTIVE: To study the place of the perineal-trans-pubic approach in the treatment of the posterior urethral post-traumatic rupture operated late, and to evaluate its results. PATIENTS AND METHODS: Twenty-four patients whose had a total posterior urethral post-traumatic rupture were treated in our department in a stage of urethral strictures. All patients underwent perineal transpubic urethroplasty. In this study we detailed a technique description of the approach and a clinical evaluation of our results. RESULTS: This technique allows having a direct approach of the posterior urethra, to perform a tension free end to end urethral suture. The backward is about 3 years. We assessed 3 cases of recurrent urethral strictures. The cases of erectile dysfunction assessed were mainly related to the initial pelvic trauma. Finally this approach had not orthopaedic squall in all cases. CONCLUSIONS: Comparing to others, the perineal transpubic approach is the best one to manage the posterior urethral injuries treated with late. It gives a satisfactory results with a few disadvantages.

[Giant retroperitoneal liposarcoma: report of a case]. / Le liposarcome rétropéritonéal géant: à propos d'un cas.

Liposarcoma is a rare and primary malignancy developed from mesenchymal tissue. We report the case of a 32-year-old woman who had a complete exeresis of a 15 cm retroperitoneal myxoid liposarcoma. Three months later, a 9 cm local recurrence was excised and radiotherapy was performed. In 2000, a local recurrence and an intestinal localisation of the liposarcoma were observed. The retroperitoneal tumor could not be removed and she had an intestinal resection followed by chemotherapy. With the literature data, we review the pathological, therapeutic and prognostic aspects of this tumor.

[Retroperitoneal schwannoma. Case report]. / Le schwannome rétropéritonéal. A propos d'un cas.

Retroperitoneal schwannoma is a rare tumor originating in the neural sheath. We report the case of a 48 year-old women. She had a ten year history of lumbal pain. The abdominal sonography had revealed a left retroperitoneal tumor that compresses the left renal cavities. The abdominal CT scan visualized a 56 mm, homogenous, well demarcated, retroperitoneal mass with a low attenuation. This mass with multiple enhanced septa is separated from the left adrenal gland. The diagnosis of a cystic lymphangioma is made. We perform surgical exeresis of the tumor by a left lumbal laparotomy. The pathology examination concludes in an altered schwannoma with Antoni B patterns. Retroperitoneal schwannoma is a primary neural benign tumor with a good prognosis. The management is surgical.

[Isolated, spontaneous hematoma of the kidney. Report of 2 cases]. / L'hematome spontane et isole du rein. A propos de 2 cas.

Spontaneous hematoma under the renal capsula is a rare pathology. The authors report two cases with one male and one female aged respectively of 50 and 63 years. The symptomatology is presented by right renal aches associated with repetitive and total hematuria in male and atypical abdominal aches in female. The radiological explorations (IVP, renal sonography and Computered Tomography) had conclude in a renal cancer in the two cases. The diagnosis is made by the pathologic study. Some etiology may be searched such as malignant tumor, an angiomyolipoma, vascular abnormalities and disturbance to the hemostasis. If no etiology is find, a nephrectomy or a simple supervision can be discussed.

[Kidney oncocytoma. Report of 7 cases]. / L'oncocytome du rein. A propos de sept cas.

Renal oncocytoma has some particularities in diagnosis and prognosis. We report a retrospective study performed between 1987 and 1999 at the department of Urology of Charles Nicolle's Hospital. Seven oncocytoma are found out of 120 renal carcinoma. Features at sonography or CT scan or arteriography can not suggest oncocytoma. The diagnosis is made at the pathology examination. Renal oncocytoma is a benign tumor. Conservative surgery will be performed as possible.

[Retroperitoneal ganglioneuroma. Report of a case]. / Le ganglioneurome rétropéritonéal. A propos d'un cas.

Retroperitoneal ganglioneurom is a primitive, rare and benign tumor originating in the neural sheath. We report the case of a 27-years old man. An abdominal sonography had revealed accidentally a 60 mm, well demarcated tumor. The left renal vein was compressed an forced back. This tumor was located in front of and internal to the left kidney. The CT scan confirmed this tumor. A left subcostal laparotomy was done. The tumor was soft and movable. A total exeresis was performed. The pathology examination had conclude in a benign ganglioneuroma. The follow-up was six years and half. Retroperitoneal ganglioneuroma is a benign tumor with a good prognosis. The treatment is surgical.

[Retroperitoneal neuroblastoma in the adult: case report and review of the literature]. / Le neuroblastome rétropéritonéal chez l'adulte: à propos d'un cas et revue de la littérature.

Retroperitoneal neuroblastoma is a rare embryonic tumor of the sympathetic nervous system that is specific to the child. In this study, the case is reported of an infant who underwent median laparotomy at the age of 14 months for a tumor which occupied the left half of the abdomen. The lesion was large, hard, and not very mobile. It was considered to be unresectable, and the histological findings after biopsy showed it to be a neuroblastoma. Radiotherapy was then initiated, which successfully reduced the tumor size. A second investigation at the age of three years detected an unresectable tumor of 5 cm. A further biopsy was performed, and the histological findings showed the lesion to be a partially developed ganglioneuroblastoma. The patient has been followed up regularly by ultrasonography which has shown no increase in tumor size. She is now 20 years old, and is asymptomatic. The last computed tomography scan visualized a 62-mm retroperitoneal mass with no metastases. Surgery was decided against in favor of regular monitoring. This case is particular due to the prolonged survival of the patient, regression of histological stage, and reduction in size of the tumor after radiotherapy. It is remarkable that the diagnosis of neuroblastoma was made when the patient was 14 months old, and that she is still alive at 20 years old.
