[Partial nephrectomy for renal masses >7cm: Morbidity, oncological and functional outcomes (UroCCR-7 study)]. / Néphrectomie partielle pour tumeur de plus de 7cm : morbidité, résultats oncologiques et fonctionnels (UroCCR-7 study).

OBJECTIVES: To describe the morbidity, mortality, oncological and functional results of Partial nephrectomy (PN) for the treatment of renal tumors of more than 7cm. MATERIAL AND METHODS: Thirty-seven partial nephrectomies for tumors larger than 7cm operated in a single center between 1987 and 2016 were analyzed retrospectively. The pre, per and postoperative clinico-biological data were collected within the UroCCR database. The GFR was assessed at day 5, 1 month and last follow-up. Intraoperative and postoperative surgical complications, the recurrence rate and the overall and specific mortality were collected. RESULTS: The mean age of the patients was 57 years (44-68). The preoperative GFR and the median tumor size were 80mL/min and 8cm, respectively. The indication for surgery was elective in 21 cases (60%) and 19 tumors (54%) were malignant. Postoperative complications occurred in 24,3 cases (24.3%). The median post-operative GFR was respectively 77mL/min, 80mL/min and 77mL/min at day 5, 1month and at last follow-up. With a median follow up of 31 months [1-168], 5 patients (26,3%) had metastatic progression of whom 1 (5.3%) had a concomitant local recurrence and 3 (15.8%) had died from cancer. CONCLUSION: This study confirms the feasibility of PN for large tumors with acceptable morbidity, limited risk of local recurrence and excellent functional results. LEVEL OF EVIDENCE: 4.

Stump infections after major lower-limb amputation: a 10-year retrospective study.

BACKGROUND AND PURPOSE: There is little published data on the diagnostic and therapeutic management of lower-limb stump infections (excluding toe and forefoot amputations). PATIENTS AND METHODS: We made a retrospective observational study of 72 patients having undergone a major lower-limb amputation for a vascular or traumatic reason, complicated by post-surgical stump infection, between January 1, 2000 and December 31, 2009. RESULTS: Stump infection was diagnosed more than 6weeks after amputation in half of the patients. Staphylococcus was the most frequently isolated bacterium. Ultrasonography and CT scan combined with fistulography were useful to confirm the diagnosis and to determine the extension of infection. Thirty-two patients (44%) needed surgical revision in addition to antibiotic treatment. Patients diagnosed with bone infection more frequently required complementary surgery than those with soft tissue infection (P<0.001). CONCLUSION: The optimal management of this type of infection requires obtaining reliable bacteriological documentation (abscess aspiration in case of soft tissue infection or bone biopsy in case of osteomyelitis) to adapt to the antibiotic treatment. The management should be multidisciplinary (orthopedic or vascular surgeons, rehabilitation specialists, and infectious diseases physicians). Most patients may use prosthesis once the infection is treated.
