[Management of patients with long term indwelling catheter: Survey of Limousin general practitioners]. / Prise en charge des patients avec sonde vesicale à demeure au long cours : enquête auprès des médecins généralistes du Limousin.

OBJECTIVE: To evaluate the management of patients with long-term (>1 month) indwelling catheter by general practitioners (GP). PATIENTS AND METHODS: A self-questionnaire was sent to 603 regional GP, between March and May 2010. It was composed of 12 multiple-choice questions and one open question, about management of their patients with indwelling catheter. RESULTS: Two hundred and twenty-eight self-questionnaires were analyzed: 126 (55%) from urban GP and 102 (45%) from rural GP. On average, each GP managed 1.3 patients with long term indwelling catheter (>1 month). The catheters were changed by the GP, urologists, and nurses in 23.2, 23.7, and 53.1%, respectively. In a majority of cases, catheters were changed every 4 weeks (59%). Nursing cares were prescribed by 64.5% of GP. Prescribed drainage bags were sterile in 42.5%. Most of GP reported to prescribe a daily change of drainage bag (56.1%). Urine analysis as performed only in case of symptomatic urine infection by 58% of respondents. Fifty percent of GP required guidelines for the management of patients with long term indwelling catheter. Rural GP managed significantly more patients with indwelling catheter, prescribed fewer sterile drainage bags, made change the drainage bag less often, and required the help of urologist less frequently. CONCLUSION: Management of long term indwelling catheter was heterogeneous among GP, and varied according to rural or urban practice. Some used significantly differed from available practice guidelines. This survey could be a basis for the preparation of an informative document aimed at GP.

[Preoperative factors of misdiagnosis of renal angiomyolipoma]. / Facteurs associés à l'échec du diagnostic préopératoire des angiomyolipomes rénaux.

OBJECTIVES: To explain the high incidence of misdiagnosis of angiomyolipoma (AML) prior to surgery. MATERIALS AND METHODS: Between 1989 and 2007, 2,657 patients were operated for a renal tumor at Dupuytren hospital in Limoges and at Cochin hospital in Paris. In 85 cases (3.2%), tumors were AMLs on pathology. The group of patients in which the diagnosis was done preoperatively was compared to the one in which the diagnosis was missed. RESULTS: Mean age of patients was 57-years-old and the sex-ratio was five women for one man. The mean size of AMLs was 5.4 cm. The patients were symptomatic in 46% of cases (39/85). The diagnosis of AML was ignored preoperatively in 62 patients (73%). In multivariate analysis, the small size of the AML, low proportion of fat and male sex were significantly associated with misdiagnosis of AML (p<0.001, p<0.018 and p<0.008, respectively). CONCLUSIONS: The incidence of misdiagnosis of AML preoperatively is high. The diagnosis seems particularly difficult when the tumor is small or contains a small proportion of fat. In addition, this study highlights that the diagnosis of AML is frequently ignored in men. The increased resolution of CTscan and the use of preoperative biopsies for tumors less than 4 cm could be helpful to decrease the incidence of useless surgery of AMLs.
