[Renal Trauma]. / Traumatismes du rein.

INTRODUCTION: Renal traumas are common, observed in 10% of patients with abdominal trauma. Most renal traumas are blunt, resulting from a direct hit or from an abrupt deceleration. MATERIAL AND METHODS: We realized a synthesis of renal trauma management for nurses. RESULTS: Clinical presentation often encompasses gross hematuria and lumbar pain. The best diagnostic tool is computed tomography (CT) urogram. Based on CT urogram images, renal traumas are classified according to the American Association for the Surgery of Trauma (AAST) classification in five grades of increasing severity. The management is conservative in the vast majority of cases and has been largely simplified over the past few years, being now mostly based on observation. Radiological interventional and endoscopic procedures are used only in very selected cases and surgical exploration has become extremely rare. CONCLUSION: The prognosis has also considerably improved and renal trauma rarely result in death or loss of the kidney nowadays.

Surgical management of renal cell carcinoma with levels III and IV tumor thrombus using the « flush ¼ technique.

OBJECTIVE: To determinate feasibility and results of the flush technique by hands for the surgical management of renal cell carcinoma (RCC) with levels III and IV inferior vena cava thrombus (VCT). MATERIALS AND METHODS: We conducted a retrospective study for all patients who underwent a surgical treatment for RCC with levels III and IV VCT in our department between June 2010 and July 2017. Sixteen patients were identified. RESULTS: All tumors were resected using a subcostal incision for right RCC and a chevron incision for the left RCC. Vena cava control was performed only on its subhepatic portion. After renal artery ligature, anesthesiologists were asked to generate a positive pressure in the small circulation. Subsequently, the vena cava was incised longitudinally to the orifice of the renal vein and the thrombus dissected and extracted of the upper part of the vena cava. Only once the supra-renal part of the vena cava was free of thrombus, the supra-renal portion of the vena cava could be clamped. We never had to perform neither thoracotomy nor hepatic mobilization. Therefore, support of a hepatic, vascular or cardiac surgeon was not necessary. The mean operative time was 201 min. The mean estimated blood loss was 2040 ml. No patient died during hospitalization, and mean hospitalization stay duration was 16.6 days. CONCLUSION: The flush technique allows a limitation of the dissection extent. It requires neither hepatic mobilization nor thoracotomy. This results in a decrease in the operative time and blood loss.

[Experience of the single scrotal approach for recurrent undescended testis after primary orchiopexy or inguinal surgery]. / Expérience de l'abord scrotal unique dans les abaissements testiculaires après chirurgie inguinale ou échec d'orchidopexie préalable.

OBJECTIVE: To report our experience of the unique scrotal incision for the redo cases of orchiopexy after previous inguinal surgery or orchiopexy for undescended testis with a special attention regarding the place of the single scrotal approach. PATIENTS AND METHODS: Thirty-six patients operated between January 2003 and September 2015 in our surgical unit for secondary orchiopexy after previous inguinal surgery or orchiopexy for undescended testis (UDT) were included in a retrospective study. The secondary surgical procedure was initiated by a scrotal incision (Bianchi). In cases of difficulty by the scrotal incision an inguinal approach by the prior skin inguinal incision was performed. Patients were divided in two groups a group 1 of 10 patients with reascending testis following inguinal hernia repair and a group 2 of 26 patients with reascending testis after previous orchiopexy for UDT. A good result was defined as testis in scrotal position without evidence of atrophy. RESULTS: All the patients of group 1 were treated by a unique scrotal incision. In group 2, seven patients required a complementary inguinal approach. One hematoma complicated a scrotal procedure leading to a testicular atrophy. A good result was achieved in 35/36 patients (97%). CONCLUSION: Single scrotal incision is an efficient and easy way to perform secondary orchiopexy after hernia repair. After surgery for UDT, as for primary cases, it cannot be an exclusive approach, higher testis need a combined or an inguinal approach. LEVEL OF EVIDENCE: 5.

Nephron sparing surgery for De Novo kidney graft tumor: results from a multicenter national study.

Nephron sparing surgery (NSS) results in the transplanted population remain unknown because they are only presented in small series or case reports. Our objective was to study renal sparing surgery for kidney graft renal cell carcinomas (RCC) in a multicenter cohort. Data were collected from 32 French transplantation centers. Cases of renal graft de novo tumors treated as RCC since the beginning of their transplantation activity were included. Seventy-nine allograft kidney de novo tumors were diagnosed. Forty-three patients (54.4%) underwent renal sparing surgery. Mean age of grafted kidneys at the time of diagnosis was 47.5 years old (26.1-72.6). The mean time between transplantation and tumor diagnosis was 142.6 months (12.2-300). Fifteen tumors were clear cell carcinomas (34.9%), and 25 (58.1%) were papillary carcinomas. Respectively, 10 (24.4%), 24 (58.3%) and 8 (19.5%) tumors were Fuhrman grade 1, 2 and 3. Nine patients had postoperative complications (20.9%) including four requiring surgery (Clavien IIIb). At the last follow-up, 41 patients had a functional kidney graft, without dialysis and no long-term complications. NSS is safe and appropriate for all small tumors of transplanted kidneys with good long-term functional and oncological outcomes, which prevent patients from returning to dialysis.
